1. Scope and Applicability

This PCR covers one nonsoap organic surfactant: straight-chain C12, non-ethoxylated sodium dodecyl sulfate (SDS, CAS151-21-3) supplied as dry powder including its measured moisture and incidental salts. The selected route is air-diluted film sulfation of n-dodecanol using purchased liquid SO3, purchased aqueous-NaOH neutralization, vacuum/film drying, actual packaging, finished storage and net factory-gate delivery. This is a narrower manufacturing method within CPC35310, not coverage of the entire surfactant class. Chemithon supports industrial unit operations; Thermo A11183.18 establishes a powder supply form, not that vendor’s manufacturing route. The actual site must independently substantiate the complete route and every operation needed to meet its declared grade.

Exclude SLES, mixed-chain SLS with different EO/alkyl distributions, other counterions, paste/aqueous-solution supply, soap, finished detergent/disinfectant formulations and downstream dilution/formulation/washing, as well as chlorosulfonic-acid, sulfuric-acid/oleum, sulfamic-acid and onsite sulfur-burning routes. The selected drying route is not presumed to be spray drying; different drying routes need new evidence. No supplier recipe, temperature, yield, energy, purity threshold or zero emission is a default. The catalogue heading99% dry basis differs from the actual supplier-CofA minimum98.5% dry basis; US loss-on-drying and non-US Karl Fischer water limits are not interchangeable or general acceptance thresholds.

market_state	Whole dry powder at actual net factory-gate delivery; net powder excludes packaging, not active kg or fixed moisture

3. Reference Flow

Field	Value
What	Supply C12 sodium dodecyl sulfate powder meeting the declared grade
How much	1 kg net actually delivered whole powder
How well	Proven actual identity, alkyl/EO profile, assay, moisture, salt and quality acceptance; not washing-service equivalence
How long or cycle	One complete actual period and matched cohorts at factory delivery; no default shelf life
reference_flow_link	delivered_powder

Field	Value
Reference amount	1
Reference product flow	Sodium dodecyl sulfate `e15fed31-c5b7-4582-a841-abd0e9b68bea`
Reference flow property	Mass `93a60a56-a3c8-11da-a746-0800200b9a66`
Reference unit group	Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66`
Reference unit	kg
Required qualifiers	actual C12 identity and CAS; alkyl and EO distributions; sodium salt; powder form and grade; water/assay/salt methods and dry/as-supplied bases; complete manufacturing and drying route; delivery gate and cohorts; returns/rework genealogy; opening/closing WIP and finished stocks with carried burdens; packaging; site and period; upstream supply and provider basis; actual G/R and original-reference-state D_rev net-delivery bridge; steam-water and external condensate masses T/P/quality/enthalpy and single upstream owner; air species in/out and gross H2O source/phase non-additive views

This reference points only to terminal row delivered_powder; its complete native limitations are retained in that card. All required qualifiers must be declared in the data package. Q is unique physical powder mass actually net delivered and accepted for the declared cohorts and complete period; it is not newly released production P. Unique lot/delivery/return genealogy deducts final returns and distinguishes first from repeat handovers; reacceptance or reshipment creates no new production, and the same finally supplied material is counted once. Undelivered closing finished stock is excluded from Q.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	reference product	Mass `93a60a56-a3c8-11da-a746-0800200b9a66`	kg	Use actual delivered net whole-powder mass, excluding drum/liner/pallet; distinguish as-supplied, dry, active and pure-C12 mass bases.
one_normalization	all inventory rows	Native extensive property	kg; kWh; MJ as declared	Convert complete raw-period numerators and retain matched carried stock burdens; only normalize_delivery divides once. Collection never divides by Q. An integrated volume receives no further time multiplier; native secondary factors are not density.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Actual purchased n-dodecanol, liquid SO3, aqueous NaOH and water received at plant, with opening stocks and carried burdens
starting_condition_role	Upstream manufactured chemical inputs; foreground begins with sulfation, not downstream detergent formulation
product_classification_scope	CPC35310 subset: C12 non-ethoxylated sodium salt dry powder
recursive_input_rule	If SDS solution/powder is purchased, record its whole procurement and background; do not also claim the same upstream synthesis occurred onsite. Reassess the boundary; constituent decomposition never creates duplicate procurement.
upstream_dataset_requirement	Match whole supplied material, assay/water/salt, route, grade, geography/year, transport interface and supplier quantity basis; a broad UUID does not prove background quantities.
disclosure	Disclose actual foreground operations, packaging and storage/handling/loading, utilities, controls, testing, cleaning and waste treatment; external transport interfaces and cut-offs. No assumed zero burdens.

rule_id	applies_to	rule	source_ids
boundary_units	sds	Include receipt/storage, SO3 vaporization, air treatment, film sulfation/cooling, prompt neutralization, vacuum/film drying, actual powder finishing, testing, packing, finished storage and factory loading; retain start-up/shutdown, failed runs, rework, cleaning and controls.	`chemithon-sulfation-1997`
boundary_interfaces	sds	Retain real upstream chemical and steam backgrounds. Model external inbound/outbound transport at declared interfaces separately; process simplification never removes actually included burdens. Downstream formulation, dilution and washing services need separate data.	`chemithon-sulfation-1997`
boundary_stocks	sds	The production ledger retains opening raw material/WIP, real material issues/returns, new release P, closing raw material/WIP and every real waste/species outlet, cancelling internal transfers. FG physical ledger: opening FG/rework WIP + P + measured gross physical returns R + other actual inward transfers + actual added materials/water = disjoint closing FG/rework WIP + measured gross physical dispatch G + other real outward transfers/returns + actual rejects, effluents and species outlets. Independently measure each handover mass, composition and moisture; real rework need not be isomass. Each addition/removal has an atomic row before data use. Cancel P on consolidation. gross_physical_dispatch and physical_return are non-additive custody views of G and R, not new production/purchase/background or quantities added to delivered_powder Q. Q remains unique net delivered accepted powder at the declared reference state; reverse the ORIGINAL accepted delivery quantity D_rev, not blindly the current returned mass R. Only proven matching state, acceptance, cohort and timing permit Q=G-D_rev; only separately proven unchanged mass/state permits D_rev=R. Rework or outside moisture change requires measured physical bridge terms, not renaming R as D_rev. Late returns correct their original delivery/report or an explicit separate adjustment, never an unrelated current Q. Trace reshipment once without creating new production or imposing first release P as denominator.
boundary_packaging	sds	For each complete drum or liner separately: opening empty + attached-to-WIP/FG + reusable stocks + actual new external acquisitions + actual external returns received = disjoint corresponding closing stocks + packages accompanying gross physical dispatch + separate external returns sent + actual waste. Measure full physical quantities; net powder Q, economic attribution and reuse cycles never shrink gross packaging movement. Internal reuse is not another purchase or credit. Returned packages incur new manufacture only for a real new acquisition; retain existing history and actual cleaning separately without duplication, checking supplier-included production once. Packaging is neither powder composition nor net powder delivery, and empty/attached/reusable states must not overlap.
boundary_nonwip	sds	Keep raw materials, WIP/FG, cooling-loop water, steam/condensate, heat-transfer fluids, oil/refrigerant charges and actual abatement consumables in separate physical opening/closing quantity, composition/state and per-exchange inherited-vector accounts; equipment hold-up is not WIP again. Instantiate specific substance accounts only when present. Declare whether raw records are receipts, actual issues or consumption already corrected for stocks; never add opening minus closing again to an already corrected consumption record. For an uncorrected ledger, derive real attribution released/carried from independent stock genealogy and include it in B_i once; installed charge and internal circulation are not new period consumption. Missing history remains a quantitative-package gap, not zero. Reconcile gross steam received, external condensate return, leakage and each water loop independently; charge thermal-service upstream burden once under the provider convention.
boundary_air_steam	sds	Steam-water supply and external condensate return are distinct gross Mass exchanges. steam_heat is the single owner of the matched upstream supplier water/energy convention; their physical cards do not add repeated boiler/treatment backgrounds or automatic return credit. Record real grade, T/P/phase/enthalpy, stock changes, flash/leaks and each receiver, never assume supply=return. Ambient air has no extra additive bulk exchange: measure the aggregate only as a non-additive raw check and record each actual N2/O2/Ar/atmospheric CO2/H2O Resource input and each real gaseous outlet separately. No fixed air recipe, purchased compressed-air default or fossil/biogenic attribution. Actual different supplies, droplet/aerosol/condensate phases and receivers require their own atomic rows before data use.	`chemithon-sulfation-1997`

Process: C12 powder manufacture and net delivery (`sds`)

This consolidated process retains internal unit and finished-warehouse ledgers and cancels their handovers. Report quantities for the emission/packaging cards where actually present; evidenced absence must be stated, and unmeasured never means zero. Add each actual extra reagent, packaging component, fuel, adsorbent, sludge or emitted species as an independent atomic row.

Inputs

Product flows

n-Dodecanol feed (`dodecanol`)

Separately acquired C12 straight-chain primary alcohol, CAS112-53-8, with actual assay, water and homolog profile. Mixed C12/14 alcohol, ethoxylated alcohol and a rheology-additive hit do not establish this feed. Purchased wet alcohol is recorded whole; constituents remain non-additive subledgers.

Purchased liquid sulfur trioxide (`so3`)

Whole actual liquid SO3 supply, CAS7446-11-9, including evidenced stabilizer/impurity fractions; vaporization and dry-air dilution occur onsite. Oleum, sulfuric acid, SO2 and SOx control products are different exchanges. Onsite sulfur combustion is outside this selected route; using it requires a separately evidenced process and all fuel, catalyst and species exchanges.

Purchased aqueous sodium hydroxide (`naoh_solution`)

Record actual supplied solution once with supplier assay and grade. NaOH active mass and carrier water are subledgers. Do not substitute a fixed30% solution,95–98% solid or0.2N reagent for an unverified actual strength. The equipment supplier example of50wt% is not a default.

Separately acquired deionised water (`water`)

Native Product flow, CAS7732-18-5, production mix at plant, has no geography or numeric quality standard; name-route says ion exchange or reverse osmosis, pure substance. The comment additionally mentions distillation, possible production/consumption mixes and plant/consumer supply. Restrict this choice to actual ion-exchange/RO DI water at its documented supply interface; distillation, actual conductivity, delivery and provider burdens require separate confirmation. The sole property is reference Mass factor1; there is no volume/density property. Count only separately acquired water, including actual DI cleaning/cooling make-up if used; exclude carrier water already in reagents and internal recirculation. Other actual water grades require their own rows.

Purchased electricity (`electricity`)

Meter mixing, pumping, SO3 vaporization auxiliaries, air compression/drying, cooling, vacuum, drying auxiliaries, milling if present, cleaning, laboratory, packaging, warehouse and electric loading. Keep failed runs and all genuine rework. Require actual voltage, grid/site/year and provider basis; no generic kWh/kg default.

Purchased steam heat (`steam_heat`)

Actual useful heat at the declared steam import gate from independently measured inlet, external-return and other outlet enthalpy flows with actual stock/loss terms under the supplier convention, covering the dryer, liquid-SO3 vaporizer and any air-dryer regeneration actually using that steam. Do not assume equal inlet/return mass or apply one return state to the whole inlet. Do not count only dryer duty while omitting vaporization heat; other actual heat sources require their own exchanges, and regeneration is not presumed to use steam. Retain line losses and actual start-up/standby allocation. Keep steam mass, condensate and leakage in a separate utility-water ledger. Do not add a duplicate boiler fuel burden when the steam provider already supplies it; onsite fuel combustion requires individual fuel and emission rows.

Steam water supplied to site (`steam_water_supply`)

Actual gross water mass entering as externally supplied steam, separate from steam_heat MJ. Record meter, actual dryness/quality, temperature, pressure, phase and specific enthalpy, supplier interface, opening/closing line hold-up and real leaks/losses. No fixed pressure, equal supply/return mass or water purity is assumed. Match the actual steam grade before binding its UUID; a pressure-specific steam identity is not universal. steam_heat owns the ONE upstream steam-generation/treatment/delivery burden under the declared supplier water/heat convention; this kg card is the physical utility-water ledger and does not buy a second steam background. Separately acquired process water excludes this same steam water.

HDPE shipping drum (`drum`)

One actual complete HDPE drum article including its integral closure; weigh it separately from net powder. Its actual composition, supplier, capacity, reuse/loss and cleaning determine the burden. Resin or generic plastic packaging is not a verified complete drum provider. Additional separately acquired closures or labels get their own rows.

Actual external return received of this usable HDPE drum; reconcile any contained powder separately without duplication. This is not new acquisition; retain ownership and history.

Sodium dodecyl sulfate (`physical_return`)

A normal commercial product return remains a Product flow with its delivered-product identity, not waste merely because it is returned. Any portion actually declared waste is separately recorded in solid_reject or another state- and destination-specific waste row; its passage through this custody view is not an additional purchase, production or disposal. Non-additive custody physical view: actual gross returned powder R received and weighed at its current state; retain original delivery quantity D_rev, original moisture/composition and actual additions/removals of material/water. Never assume R equals D_rev. Rewashing/redrying/screening and waste retain their true atomic directions. This is neither new purchase nor production; attach no repeated manufacturing background and do not add this view to net Q. Reverse the original delivered quantity at its original reference state; late returns do not reduce unrelated current Q. The same complete native identity restrictions as delivered_powder follow. Native identity explicitly describes the12-carbon sodium organosulfate CH3(CH2)11OSO3Na, an anionic amphiphile with a hydrocarbon tail and polar head used in cleaning/hygiene. The native name declares Production mix, at plant, with no grade or route; no geography/locationOfSupply or CAS field. The sole property is reference Mass factor1. Native class35499 is a classification defect relative to this specific surfactant identity, retained for upstream correction; it is not chemical exclusion evidence. This UUID conditionally locates the whole C12 powder with measured moisture and incidental salts, not pure-active kg, SLES, mixed-chain SLS, a supplier process, guaranteed assay or density. Confirm actual lot identity, alkyl distribution, non-ethoxylation, form, assay/water/salt fractions, manufacturing route and delivery/provider basis. The catalogue powder specification proves a market form, not the vendor’s route.

Sodium dodecyl sulfate (`gross_physical_dispatch`)

Retain each handover net powder mass, composition/moisture, acceptance, cohort and original delivery ID including reshipments; unaccepted or off-state G remains separate, never automatically Q. Do not reduce actual G by stock-burden corrections or economic allocation and never add it to net Q. The same complete native identity restrictions as delivered_powder follow. Native identity explicitly describes the12-carbon sodium organosulfate CH3(CH2)11OSO3Na, an anionic amphiphile with a hydrocarbon tail and polar head used in cleaning/hygiene. The native name declares Production mix, at plant, with no grade or route; no geography/locationOfSupply or CAS field. The sole property is reference Mass factor1. Native class35499 is a classification defect relative to this specific surfactant identity, retained for upstream correction; it is not chemical exclusion evidence. This UUID conditionally locates the whole C12 powder with measured moisture and incidental salts, not pure-active kg, SLES, mixed-chain SLS, a supplier process, guaranteed assay or density. Confirm actual lot identity, alkyl distribution, non-ethoxylation, form, assay/water/salt fractions, manufacturing route and delivery/provider basis. The catalogue powder specification proves a market form, not the vendor’s route.

Steam condensate returned to external supplier (`external_condensate_return`)

Actual gross liquid steam-condensate return crossing the external supplier interface, Product return rather than wastewater or atmospheric H2O. Record independent return mass, actual temperature/pressure/phase/enthalpy, water quality/contamination, receiver/ownership and stocks/losses. Do not force its mass or quality equal to supplied steam; distinguish internally reused condensate, actual exported waste and flash vapour, each on its real phase/destination. This mass return carries only the documented supplier return convention; it is not a second heat purchase, generic avoided-production credit or a duplicate water background. The steam_heat owner accounts the supplier energy/water burden once.

Waste flows

Exported manufacturing wastewater (`wastewater`)

One actual wastewater stream sent across the treatment boundary, with water, sulfate, sodium, SDS and other actual constituents assayed as subledgers. Include actual scrubber purge, cleaning and condensate only where they physically join this stream. Condensate reused internally is not exported again. A treatment-service mass is not an elementary discharge; if treatment is onsite, model its actual inputs, sludge and individual final species instead without duplicating this transfer.

dinitrogen (`n2_out`)

Independently measure actual gas/species mass at the actual inlet or outlet from calibrated dry/wet flow, temperature, pressure, humidity and species analysis; no fixed atmospheric composition, process quantity or assumed inlet/outlet equality. Record source/state and actual transformations/hold-up; add every other observed species separately. Actual gross gaseous outlet including unchanged carrier gas. Native Elementary/Mass reference index0 factor1, CAS7727-37-9, Emissions to air, unspecified. A known more-specific actual compartment requires its own verified identity, never downgrade. Resource-input identities cannot be used as Emission outputs. Retain gross inlet/outlet and net change for each species instead of dropping unchanged carrier mass while retaining pollutants.

SDS emitted to air (`sds_air`)

Actual post-control/fugitive SDS mass supported by measured dust and independent composition. Native SLES or ammonium dodecyl sulfate hits are different chemicals. Do not add the same chemical dust mass again as total particulate matter; any alternative particulate characterization must be explicitly reconciled with non-overlapping particle-size fractions.

Native Elementary flow CAS151-21-3, reference Mass index0 factor1, with no fixed geography, grade, manufacturing route, particle size or emission amount. The receiving compartment is strictly Emissions to air, unspecified. Use only when that compartment matches the actual study inventory; real indoor, urban, stack-height or long-term evidence requires a separately verified matching flow instead of downgrading to unspecified air. Broad synonyms mentioning ether sulfate or sulfonate do not change this CAS151-21-3 sodium sulfate-ester identity; never bind SLES, ammonium salt or total uncharacterised dust.

Water vapour emitted to air (`water_air`)

Measure the complete actual gross gaseous H2O at each external outlet after condensate separation, including uncondensed carrier humidity and process-source water vapour. Retain non-additive source subledgers for atmospheric humidity, reagent water, independently proven reaction water, actual steam leaks and other real sources. Net increment E is only a reconciliation view derived from the same gross inlet/outlet and other real water outlets/stocks; never add another copy of H2O emission for E. Gaseous H2O excludes droplets, aerosol-carried water, condensate and internal reuse; each follows its actual phase and receiver in separate atomic rows. Drying is physical transfer, not proof of reaction water; retain actual free/bound/hydration state and do not treat loss-on-drying as pure water.

7. Allocation and Co-product Handling

rule_id	applies_to	rule	source_ids
allocation_subdivide	sds	First subdivide by actual cohort and unit meters; retain shared-unit start-up and failed burdens. Use evidenced causal drivers such as runtime/throughput for shared services, disclosing driver, values and uncertainty; no default sales-value allocation.
allocation_recycle	sds	No co-product is presumed. Internal acid/paste/powder/condensate recycling and handover P create no extra purchase, production or credit. An actually saleable by-product requires proven quality/function and independent export plus allocation review; wastewater, sludge and salt impurities are not automatically co-products.	`chemithon-sulfation-1997`
asset_manufacture_conservation	existing capital/reusable manufacture attribution	Within the applicable allocation decision context, original manufacture burden attributed across uses of actual capital equipment or reusable articles already included in foreground production, packaging or observed services uses one persistent same-asset ledger across all crops, products, cohorts, manufacturing/postrelease services, owners and observation periods. D is its supported whole installed service: all realized historical service plus supported remaining service in the same units as actual beneficiary use u; D must be finite and positive. Period capacity, remaining-only capacity, the physical asset/article mass alone, or current-period product Q alone is not D; supported whole-service throughput in mass units may be used when it demonstrates the causal service and matches u. This does not amortize the manufactured reference product over downstream life or change its declared reference gate/Q. The fractions u/D and all previously assigned manufacture shares together must never exceed 1. Changes of window, custody, provider or repair never restart the original manufacture balance. Replacements have distinct identities and only their real new manufacture vectors; actual repair and treatment increments remain separately accounted. Revised capacity evidence requires transparent reconciliation of prior shares and sensitivity, not a fresh ledger. Keep full physical mass and stock movements independent of burden shares. Unknown D, prior shares or beneficiary coverage requires review and no final manufacture-attributed amount; no assumed lifetime, utilization, zero or arbitrary division is permitted. For each existing collection protocol that attributes manufacture of included production, packaging or observed-service assets across uses in this route (excluding amortization of the manufactured reference product itself), additionally retain a durable asset identity, its measured full physical mass and acquisition/installation/retirement stock history, original manufacture burden vector, all historical and current beneficiaries, matched-unit service readings, the evidenced whole installed-service denominator D, supported remaining-service basis and uncertainty, prior assigned shares and remaining original manufacture balance. Carry the ledger across reporting windows and custody/provider changes. Collect actual repair, replacement, recovery and treatment separately; these records do not normalize physical movements or create an additional asset purchase. These are added fields and conservation obligations for the existing applicable protocols, not a new assumed capital inventory.

8. Foreground Data Collection, Calculation, and Quality Rules

Each protocol has a distinct owner. Physical event m_i and inherited/attributed burden B_i are separate ledgers; never modify event mass by a burden correction. Gross custody G/R, net reference Q, air bulk/species and water source/E views have explicit non-additivity. collection_method retains raw-period numerators, stocks and carried burdens without division by Q. aggregation_rule declares only the final reporting basis; it neither performs A/Q during collection nor divides again after a card formula. Only normalize_delivery owns normalization.

Data Collection Protocols

For each existing collection protocol that attributes manufacture of included production, packaging or observed-service assets across uses in this route (excluding amortization of the manufactured reference product itself), additionally retain a durable asset identity, its measured full physical mass and acquisition/installation/retirement stock history, original manufacture burden vector, all historical and current beneficiaries, matched-unit service readings, the evidenced whole installed-service denominator D, supported remaining-service basis and uncertainty, prior assigned shares and remaining original manufacture balance. Carry the ledger across reporting windows and custody/provider changes. Collect actual repair, replacement, recovery and treatment separately; these records do not normalize physical movements or create an additional asset purchase. These are added fields and conservation obligations for the existing applicable protocols, not a new assumed capital inventory.

Determine eligible net Q only by delivery_mass_bridge and unique genealogy, not assumed G-R or first-release P. Record all actual rework additions/removals and identify late original-report adjustments. G/R cards are non-additive custody observations and delivered_powder is the net reporting reference; retain raw amounts without stock-burden/economic shrinkage or repeated procurement.

Do not correct again when material consumption already uses real issues/returns/stock changes; include WIP/FG and non-WIP history released to the attributable B_i once. Link returned old deliveries to original delivery and complete history before adding real incremental rework; preserve historical normalization bases for interpretation/reversal, while this report denominator still matches declared net delivery Q.

Retain bulk air/gas totals only as non-additive checks against independently measured species sums; no bulk air_in Resource/Emission row is added to species. Distinguish gas H2O, droplets/aerosol water, collected condensate, actual offsite waste and internal reuse. New actual phase/receiver/formulation requires its own atomic row before data use. Physical raw movements stay gross, without burden-vector corrections, allocation or collection division; no residual fits multiple unknowns.	kg; m3; h; degC; Pa	continuous/each lot outlet and waste handover	complete actual period including control start-up and failed runs	actual outlets and treatment boundary	per 1 kg reference flow	calibrated meters, waste manifests, water/composition and treatment evidence

N2/O2/Ar/atmospheric CO2 and humidity have real Resource inputs and gross gas outlets; no fixed atmosphere fractions, equal pass-through or fossil/biogenic default. Report water_air as gross gaseous H2O with non-additive atmospheric/process origins; net E is only a check. Separately collect phase water and actual reaction extent/acid-base assays, interferences, detection limits and uncertainties. Never solve several species or reaction water from COD/one residual; retain unnormalized quantities, no physical allocation or stock-burden reduction.	kg; mol; mg/m3; m3; mass fraction	each batch and outlet monitoring representative of the complete period	same cohorts and complete period including abnormal and rework activity	actual reaction stages and post-control/fugitive outlets	per 1 kg reference flow	independent assay/species reports, volume/concentration bases, reaction evidence and uncertainty

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
normalize_delivery	all inventory rows	Keep TWO linked ledgers. Physical directional events retain their measured gross raw quantities m_i after unit conversion; report m_i/Q once where a unit view is needed. Do not subtract inherited burdens or apply economic allocation to physical mass. In particular G, R, steam-water supply/condensate return, each gas species and packaging directions retain actual event quantities; the G/R custody views and net reference Q are alternatives, never additive production/purchase. Separately, delivery-cohort BURDEN numerator B_i equals matched opening raw-material/WIP/FG/non-WIP inherited exchange vectors plus complete actual-period attributable exchanges minus only documented vectors retained in closing/undelivered stock or transferred to independent cohorts. Preserve failed/zero-output runs, losses, actual rework, packaging, storage/loading and original-delivery reversals; use genealogy and causal allocation once. Already stock-corrected consumption is not corrected again. No glass/powder stock scalar substitutes for every exchange vector. Divide each completed B_i/Q exactly once after conversion/attribution; it is the burden result, not a correction of physical m_i. A physical view never buys the same background again: steam_heat owns the steam supplier water/energy convention once and G/R carries existing SDS history without another procurement. Cards and aggregation only reference these same single reporting operations. Q from delivery_mass_bridge stays the declared net-delivery gate, never P or an unrelated historical Q. For Q<=0 retain raw physical/burden records without a unit result and resolve eligibility/adjustments before dataset completion.	cp_material; cp_energy; cp_pack; cp_delivery; cp_stocks; cp_outlet; cp_species	Exchange amount per 1 kg reference flow
delivery_mass_bridge	delivered_powder; gross_physical_dispatch; physical_return	From original accepted delivery/return genealogy, Q is the sum of eligible accepted delivery entries at their actually weighed declared reference state minus D_rev, the sum of original accepted-entry quantities reversed. G is all physical dispatch; R is the actual physical returned quantity at its current mass/composition/moisture. D_rev uses the ORIGINAL accepted quantity/state and is not inferred from R. Q=G-D_rev is permitted only where all G has matching acceptance/reference state, cohort, reporting interval and unique-event evidence. G-R is not a net-delivery shortcut when moisture, composition, screening/rework or timing changed. Reconcile each measured addition/removal and distinct original versus returned state; no assumed isomass. Reshipments count only as actual eligible events after original reversal, never as new production or duplicated final supply; late old-cohort returns update the original report or an explicit separate adjustment. delivered_powder=1kg is the net reference view, while G/Q and R/Q are non-additive custody observations, not a third powder output or another supplier purchase. Preserve actual first release P internally and retained/failed/zero-Q burdens; no unmeasured bridge term is zero.	cp_delivery; cp_stocks; cp_species	Measured G/R and original-state reversals linked to net Q
raw_conversions	all inventory rows	Use calibrated mass or actual volume times independent substance-specific density with composition/temperature/pressure and phase bases retained. Rate integrates only over its true measured interval; integrated gas/liquid volume receives no second time multiplier. Gas species use measured concentration/composition and matched dry/wet gas quantity; do not substitute bulk-air volume for water volume or fix atmospheric fractions. For the declared steam boundary use actual entering enthalpy flow minus independently measured returning/exported enthalpy flows and the actual stock/other-outlet terms under the supplier convention; do not assume equal steam/condensate mass or quality and do not apply one return enthalpy to all supplied steam. Retain line losses and actual leakage destinations; utility-water kg and heat MJ reconcile separately. kWh and MJ remain explicit.	cp_material; cp_energy; cp_outlet; cp_species	Converted raw numerators before normalization
constituent_ledger	dodecanol; so3; naoh_solution; delivered_powder; wastewater	Each constituent mass equals whole actual supply/outlet mass times independently assayed mass fraction on a compatible basis. Converting dry assay to as-supplied needs actual same-lot water; loss-on-drying is not automatically water. Active titration equivalents, C12 profile and EO are distinct. Count a purchased formulation/solution once; constituent/carrier-water subledgers never duplicate procurement. Onsite blending instead records actual separately acquired constituents and real blending energy/loss.	cp_material; cp_delivery; cp_species	Non-additive constituent/carrier-water subledgers	`thermo-sds-a11183-2026`
mass_elements_water	all inventory rows	Use ACTUAL G and R in physical manufacture/FG and consolidated gates, not Q as a substitute for gross movement. External physical inputs including steam-water and each ambient species + opening disjoint raw/WIP/FG/non-WIP stocks = G + external condensate return + every actual gas/liquid/solid outlet + closing stocks + other independently identified outward transfers; cancel P and internal recirculation. R is an external physical input at its measured return state; original delivery reversal D_rev belongs to the reporting bridge, not an extra physical outlet. Q is a non-additive net reference view. Reconcile complete mass and C/H/O/Na/S, plus relevant N/Ar and every actual species, independently. Bulk wet-air/gas observations are non-additive checks against species sums, never extra Resource/Emission alongside contained species. Gaseous H2O includes all uncondensed carrier and process-source water; source fractions and net increment E are non-additive subledgers, not more H2O outputs. Droplets, condensate, aerosol-carried water and other real phases have separate atomic receiver-specific flows. Independently distinguish reagent/carrier water, incoming humidity, steam water/leaks, free/bound/structural water, reaction extent and actual water outlets. One residual cannot solve several unknown species or water terms. Close steam and other non-WIP loops with actual hold-up/losses; physical steam kg is not MJ. Preserve the complete per-article packaging equation and all gross directions; neither burden allocation nor stock-vector attribution shrinks physical events.	cp_material; cp_delivery; cp_stocks; cp_outlet; cp_species	Independent physical, element and stage-water balances
reaction_species	sds	Stoichiometric checks only: C12H25OH+SO3→C12H25OSO3H forms no net water; C12H25OSO3H+NaOH→C12H25OSO3Na+H2O. Actual reaction water needs independent acid-base assay, reaction extent and side-reaction evidence, never complete conversion presumed from delivered powder kg. Actual SO3 hydration, free-sulfuric-acid neutralization and organosulfate hydrolysis need separately supported extents and water consumption/formation. Never import water/HCl from sulfuric-acid/oleum or chlorosulfonic routes. Outlet species require independent concentration/volume/medium evidence; COD, total sulfur and closure residuals neither identify species nor fit unknown reaction water and another unknown outlet together.	cp_material; cp_species; cp_outlet	Independent reaction-extent and actual species/reaction-water records	`chemithon-sulfation-1997`
asset_manufacture_share	existing capital/reusable manufacture attribution	For each included original asset manufacture vector B, f_current = u_current / D only after the persistent ledger verifies the supported whole installed-service denominator, all beneficiaries and prior assigned shares. Attribute f_current * B once to the actual beneficiary before the existing single reference normalization. Check prior_shares + all current/new beneficiary shares <= 1; carry the remaining original balance. Capacity revisions reconcile the historical ledger. Full physical asset/packaging mass and actual gross stocks/returns never receive f_current. Unknown D or history leaves the final attributed result unavailable, without suppressing actual repair/replacement/service burdens.	asset_id; original_B; u_current; D; historical_beneficiaries; prior_shares; capacity_evidence	conserved attributed manufacture vector

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
identity_quality	reference and inputs	Independently verify C12/EO/sodium/form/grade/route; distinguish whole supply from active/water/salt subledgers. All native name, comment, geography, medium and property limits apply; classification labels or similar names do not replace chemical identity.	`thermo-sds-a11183-2026`
cohort_quality	all inventory rows	Trace complete actual periods/cohorts, failed zero-output runs, rework and historical stock burdens; separate release P from actual net delivery Q. Never delete actually included storage, packaging and loading burdens.	cp_stocks; cp_delivery; cp_energy; cp_pack
species_quality	water and outlets	Independently calibrate mass/volume, assay and species analysis; retain detection limits, wet/dry gas, temperature/pressure and uncertainty. Physical/element balances and reaction-water evidence stand separately; no residual or COD fitting.	cp_outlet; cp_species
transferability	dataset	Thermo specifies no manufacturing route; Chemithon1997 is equipment technical guidance covering broad alcohol/ether sulfates and other chemical routes, not this product’s factory inventory. Adopt applicable unit principles only; no example recipe, conditions, yield, heat/electricity, moisture or active level becomes a general default.	`chemithon-sulfation-1997`; `thermo-sds-a11183-2026`

9. Validation Rules

rule_id	applies_to	rule	source_ids
validate_identity	delivered_powder	Reference must select one unique terminal Product row with the same UUID and physical row in both languages; never rename/hide intermediate acid/paste or a real co-product to evade checks. The package must substantiate every reference qualifier and actual route; SLES/other chain distributions/salts/supply concentrations are not interchangeable.	`thermo-sds-a11183-2026`
validate_gate	all inventory rows	Check Q from actual accepted reference-state delivery entries and original D_rev with complete event/custody genealogy. Independently verify G and R physical masses and rework/moisture changes; never equate R to D_rev without matching-state evidence or substitute net Q for G in a physical balance. P is internal, undelivered FG not Q, and G/R custody views add no production or procurement to the net reference. Normalize physical event quantities and separately attributed burden vectors once only; Q<=0 retains raw records without a unit result.
validate_balance	all inventory rows	Validate actual steam input and external condensate output in Mass with T/P/phase/quality/enthalpy and independently measured stocks/losses; one supplier burden owner prevents double steam-water/heat background. Require separate actual Resource air-species inputs and gross gaseous species outputs with true compartments; bulk air, source-water fractions and net E are non-additive views. Never use an Emission as Resource or assume atmospheric CO2 fossil/biogenic origin. Independently close all physical/species/element/phase-water gates using G/R and actual additions/outlets, not Q. No duplicate whole supply and constituents; no extra time for integrated volume; no COD or shared residual fitting of multiple species/reaction-water unknowns.
validate_completeness	dataset	Each row requires raw evidence, protocol owner, actual quantity basis and compatible flow/property/medium. Disclose unmatched auxiliary UUIDs/backgrounds without invented defaults or deleted real burdens. Format validation does not establish scientific methodology approval.
validate_asset_manufacture_conservation	existing capital/reusable manufacture attribution	For every included capital/reusable manufacture attribution verify same-asset continuity, whole installed service in matched units, all historical/current beneficiaries, prior assigned manufacture shares and cumulative share <= 1. Reject a reset by period, cohort, provider, owner or repair. Check distinct real replacement and incremental repair/treatment vectors separately and preserve gross physical mass. A missing denominator, unexplained previous allocation or incomplete beneficiary ledger requires explicit review and an unavailable final attributed amount; structural inspection cannot claim empirical completeness.

System boundary rules · 6

Rule ID	Applies to	Rule	Source IDs
`boundary_units`	sds	Include receipt/storage, SO3 vaporization, air treatment, film sulfation/cooling, prompt neutralization, vacuum/film drying, actual powder finishing, testing, packing, finished storage and factory loading; retain start-up/shutdown, failed runs, rework, cleaning and controls.	chemithon-sulfation-1997
`boundary_interfaces`	sds	Retain real upstream chemical and steam backgrounds. Model external inbound/outbound transport at declared interfaces separately; process simplification never removes actually included burdens. Downstream formulation, dilution and washing services need separate data.	chemithon-sulfation-1997
`boundary_stocks`	sds	The production ledger retains opening raw material/WIP, real material issues/returns, new release P, closing raw material/WIP and every real waste/species outlet, cancelling internal transfers. FG physical ledger: opening FG/rework WIP + P + measured gross physical returns R + other actual inward transfers + actual added materials/water = disjoint closing FG/rework WIP + measured gross physical dispatch G + other real outward transfers/returns + actual rejects, effluents and species outlets. Independently measure each handover mass, composition and moisture; real rework need not be isomass. Each addition/removal has an atomic row before data use. Cancel P on consolidation. gross_physical_dispatch and physical_return are non-additive custody views of G and R, not new production/purchase/background or quantities added to delivered_powder Q. Q remains unique net delivered accepted powder at the declared reference state; reverse the ORIGINAL accepted delivery quantity D_rev, not blindly the current returned mass R. Only proven matching state, acceptance, cohort and timing permit Q=G-D_rev; only separately proven unchanged mass/state permits D_rev=R. Rework or outside moisture change requires measured physical bridge terms, not renaming R as D_rev. Late returns correct their original delivery/report or an explicit separate adjustment, never an unrelated current Q. Trace reshipment once without creating new production or imposing first release P as denominator.
`boundary_packaging`	sds	For each complete drum or liner separately: opening empty + attached-to-WIP/FG + reusable stocks + actual new external acquisitions + actual external returns received = disjoint corresponding closing stocks + packages accompanying gross physical dispatch + separate external returns sent + actual waste. Measure full physical quantities; net powder Q, economic attribution and reuse cycles never shrink gross packaging movement. Internal reuse is not another purchase or credit. Returned packages incur new manufacture only for a real new acquisition; retain existing history and actual cleaning separately without duplication, checking supplier-included production once. Packaging is neither powder composition nor net powder delivery, and empty/attached/reusable states must not overlap.
`boundary_nonwip`	sds	Keep raw materials, WIP/FG, cooling-loop water, steam/condensate, heat-transfer fluids, oil/refrigerant charges and actual abatement consumables in separate physical opening/closing quantity, composition/state and per-exchange inherited-vector accounts; equipment hold-up is not WIP again. Instantiate specific substance accounts only when present. Declare whether raw records are receipts, actual issues or consumption already corrected for stocks; never add opening minus closing again to an already corrected consumption record. For an uncorrected ledger, derive real attribution released/carried from independent stock genealogy and include it in B_i once; installed charge and internal circulation are not new period consumption. Missing history remains a quantitative-package gap, not zero. Reconcile gross steam received, external condensate return, leakage and each water loop independently; charge thermal-service upstream burden once under the provider convention.
`boundary_air_steam`	sds	Steam-water supply and external condensate return are distinct gross Mass exchanges. steam_heat is the single owner of the matched upstream supplier water/energy convention; their physical cards do not add repeated boiler/treatment backgrounds or automatic return credit. Record real grade, T/P/phase/enthalpy, stock changes, flash/leaks and each receiver, never assume supply=return. Ambient air has no extra additive bulk exchange: measure the aggregate only as a non-additive raw check and record each actual N2/O2/Ar/atmospheric CO2/H2O Resource input and each real gaseous outlet separately. No fixed air recipe, purchased compressed-air default or fossil/biogenic attribution. Actual different supplies, droplet/aerosol/condensate phases and receivers require their own atomic rows before data use.	chemithon-sulfation-1997

Allocation rules · 3

Rule ID	Applies to	Rule	Source IDs
`allocation_subdivide`	sds	First subdivide by actual cohort and unit meters; retain shared-unit start-up and failed burdens. Use evidenced causal drivers such as runtime/throughput for shared services, disclosing driver, values and uncertainty; no default sales-value allocation.
`allocation_recycle`	sds	No co-product is presumed. Internal acid/paste/powder/condensate recycling and handover P create no extra purchase, production or credit. An actually saleable by-product requires proven quality/function and independent export plus allocation review; wastewater, sludge and salt impurities are not automatically co-products.	chemithon-sulfation-1997
`asset_manufacture_conservation`	existing capital/reusable manufacture attribution	Within the applicable allocation decision context, original manufacture burden attributed across uses of actual capital equipment or reusable articles already included in foreground production, packaging or observed services uses one persistent same-asset ledger across all crops, products, cohorts, manufacturing/postrelease services, owners and observation periods. D is its supported whole installed service: all realized historical service plus supported remaining service in the same units as actual beneficiary use u; D must be finite and positive. Period capacity, remaining-only capacity, the physical asset/article mass alone, or current-period product Q alone is not D; supported whole-service throughput in mass units may be used when it demonstrates the causal service and matches u. This does not amortize the manufactured reference product over downstream life or change its declared reference gate/Q. The fractions u/D and all previously assigned manufacture shares together must never exceed 1. Changes of window, custody, provider or repair never restart the original manufacture balance. Replacements have distinct identities and only their real new manufacture vectors; actual repair and treatment increments remain separately accounted. Revised capacity evidence requires transparent reconciliation of prior shares and sensitivity, not a fresh ledger. Keep full physical mass and stock movements independent of burden shares. Unknown D, prior shares or beneficiary coverage requires review and no final manufacture-attributed amount; no assumed lifetime, utilization, zero or arbitrary division is permitted. For each existing collection protocol that attributes manufacture of included production, packaging or observed-service assets across uses in this route (excluding amortization of the manufactured reference product itself), additionally retain a durable asset identity, its measured full physical mass and acquisition/installation/retirement stock history, original manufacture burden vector, all historical and current beneficiaries, matched-unit service readings, the evidenced whole installed-service denominator D, supported remaining-service basis and uncertainty, prior assigned shares and remaining original manufacture balance. Carry the ledger across reporting windows and custody/provider changes. Collect actual repair, replacement, recovery and treatment separately; these records do not normalize physical movements or create an additional asset purchase. These are added fields and conservation obligations for the existing applicable protocols, not a new assumed capital inventory.

`validate_gate`	all inventory rows	Check Q from actual accepted reference-state delivery entries and original D_rev with complete event/custody genealogy. Independently verify G and R physical masses and rework/moisture changes; never equate R to D_rev without matching-state evidence or substitute net Q for G in a physical balance. P is internal, undelivered FG not Q, and G/R custody views add no production or procurement to the net reference. Normalize physical event quantities and separately attributed burden vectors once only; Q<=0 retains raw records without a unit result.
`validate_balance`	all inventory rows	Validate actual steam input and external condensate output in Mass with T/P/phase/quality/enthalpy and independently measured stocks/losses; one supplier burden owner prevents double steam-water/heat background. Require separate actual Resource air-species inputs and gross gaseous species outputs with true compartments; bulk air, source-water fractions and net E are non-additive views. Never use an Emission as Resource or assume atmospheric CO2 fossil/biogenic origin. Independently close all physical/species/element/phase-water gates using G/R and actual additions/outlets, not Q. No duplicate whole supply and constituents; no extra time for integrated volume; no COD or shared residual fitting of multiple species/reaction-water unknowns.
`validate_completeness`	dataset	Each row requires raw evidence, protocol owner, actual quantity basis and compatible flow/property/medium. Disclose unmatched auxiliary UUIDs/backgrounds without invented defaults or deleted real burdens. Format validation does not establish scientific methodology approval.

Reject a reset by period, cohort, provider, owner or repair. Check distinct real replacement and incremental repair/treatment vectors separately and preserve gross physical mass. A missing denominator, unexplained previous allocation or incomplete beneficiary ledger requires explicit review and an unavailable final attributed amount; structural inspection cannot claim empirical completeness.
