Nitrogen-pressurised aqueous ethanol/DPnP room-fragrance aerosol manufacture

1. Scope and Applicability

This PCR covers one narrower physical manufacturing route: blend separately received water, ethanol feed, dipropylene glycol n-propyl ether (DPnP) and purchased fragrance oil blend without separately added surfactant or corrosion inhibitor; fill printed tinplate aerosol cans, fit conventional crimped valves, charge purchased gaseous nitrogen, fit PP actuators/overcaps and shipping cartons, and release the qualified finished aerosol. The representative route uses purchased DI water, electric services and onsite compressed-air generation. Actual recipe, sequence, mixing conditions, gas purity/pressure, test method and can compatibility must be independently evidenced; no patent percentages, equipment capacity, cycle consumption or example operating conditions become default LCI values. [ep3481439-aerosol; zigler-nitrogen-filling]

The independent method need is the retained gas plus pressure-container manufacture/filling boundary and the actual DPnP co-solvent route, not the room-use label. Bulk fragrance concentrate is an upstream input, not the finished preparation. Hydroalcoholic body perfume with an otherwise identical supported physical route may be conditionally reused or revised under one identity after independent boundary review; dual-use labelling alone never justifies a duplicate PCR. This method does not claim the entire CPC35331 leaf. Exclude pump-only perfume, gels, impregnated substrates, candles/incense, adsorbent blocks, BOV, LPG/DME propellants, other co-solvents, onsite fragrance/ethanol/N2 synthesis and standalone air-cleaning/disinfection services. Different actual ingredients or operations need explicit atomic additions and boundary review, rather than suppression to fit this representative route. [un-cpc3-2025]

What	Supply a qualified room-fragrance aerosol preparation
How much	1 kg
How well	Actual accepted composition and pressure-container specification; no assumed disinfectant efficacy, odour removal equivalence or purification service
How long or cycle	One first production-quality-release event; no default service life, room area, dose or shelf life

Missing required qualifiers make the concrete dataset reference incomplete. The manufactured-at-plant generic native reference establishes physical identity only; its complete limits are retained on finished_aerosol. Packaging is outside the reference mass but inside the production burden.

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	Q is the unique positive net contents mass first newly quality-released in the matched production period/cohort, including retained propellant and carrier water, excluding all container/packaging tare. Q is not dispatch mass.
single_basis	all inventory denominators	Mass	kg	Convert complete attributable raw numerators to their own units, then normalize once to positive Q; retain energy and emission units. Integrated gas/liquid volume receives no additional time multiplier.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Purchased complete ingredients, supplied gaseous nitrogen, finished empty pressure packaging and their carried opening inventory burdens at the formulation/filling site
starting_condition_role	Receiving and physical formulation/filling, not upstream manufacture as an omitted free input
product_classification_scope	CPC 3.0 35331; narrower
recursive_input_rule	A purchased room-fragrance premix is one whole commercial input with full upstream formulation burdens, not an unburdened same-category shortcut. It changes the selected separately charged route and needs an explicit boundary revision, without duplicate constituent procurement.
upstream_dataset_requirement	Match actual complete supplied form, concentration, grade, route, gas state, geography and delivery; retain upstream chemical synthesis, gas separation/compression, packaging fabrication/coating/printing and transport burdens
disclosure	Declare production-release gate separately from warehouse/dispatch, physical cohort, actual packaging/tests/cleaning, shared utilities, storage/handling, exclusions, allocation and complete opening/closing WIP/stock burdens

rule_id	applies_to	rule	source_ids
boundary_production	aerosol	Include receiving/storage, blending, transfer, can filling, valve crimping, nitrogen charging, actual pressure/leak/quality tests, packing and first release, cleaning, failed runs and all upstream burdens. Retain actual heat/fuel/refrigerant/laboratory consumables with separate atomic exchanges if present; this representative electric route never licenses their omission.	ep3481439-aerosol; zigler-nitrogen-filling
boundary_cohort	aerosol	Finished warehouse/handling/dispatch is a separate raw ledger for the same released cohort when included. Eliminate its internal receipt from production on consolidation, retain its actual attributable burdens, and never add closing finished goods of Q as another production output. No automatic equivalence of released and delivered kg.
boundary_use	reference product	Use-stage spraying, room exposure, device power, lifetime, area, deodorization/disinfection/air-cleaning function and end-of-life are outside this production inventory and need separate evidence and boundaries. Do not move real manufacturing test sprays or packaging into the excluded use stage.

Inputs

Product flows

Purchased ethanol feed (ethanol)

Native Product/Mass identity is ethanol CAS64-17-5, production mix at plant, with no specified concentration, grade, route or geography. The native class35499 is a classification debt, not evidence for a different molecule or a residual-only chemical identity. Use one complete purchased ethanol supply, including actual water and denaturants when present, with verified composition/provider reconciliation; do not silently bind a pure-ethanol provider to a hydrous or denatured formulation. Water and denaturants in that supply are non-additive constituent subledgers. Other purchased denaturants need separate cards. The generic ethanol molecular candidate is not bound to this whole commercial solution pending complete supply-state identity; this auxiliary gap does not change the finished reference. No native coefficient is a density.

DPnP co-solvent charge (dpnp)

Record the complete supplied DPnP grade with actual isomer distribution, assay, carrier and impurities. DPM (methyl ether), DPG (unetherified glycol), ethylene glycol ethers and propylene-glycol n-propyl ether are different identities and cannot substitute. The patent identifies DPnP but establishes no supplier grade, density or actual charge. UUID remains unbound.

Purchased fragrance oil blend (fragrance)

Native Product/Mass, generic at plant, purchased fragrance oil blend, with no CAS, fixed composition, grade, geographic location or quantitative properties beyond reference Mass factor1. This is one purchased whole mixture, not duplicate procurement of its individual constituents. Obtain complete supplier composition and carrier basis for upstream matching, mass/element balances and actual emitted-species identification. A scent name does not supply these data.

Separately added formulation water (formulation_water)

Native Product/Mass, CAS7732-18-5, production mix at plant; name-route specifies ion exchange or reverse osmosis, pure substance. Comment additionally mentions distillation and production/consumption supply; no numerical quality standard or geography is specified. Restrict this binding to actually matched purchased ion-exchange/RO deionised water. Distilled-only water or onsite treatment requires its own verified identity and complete treatment inventory. Exclude water already inside purchased ethanol/fragrance from this separate procurement row.

Gaseous nitrogen propellant supply (nitrogen)

Measure actual supplied gas mass, purity, pressure, temperature, delivery and production route; include line charging, purge, failed filling and retained propellant. The native air-separation N2 candidate has reference Mass coefficient1.25 without a volume property or stated density conditions; it is not adopted and never used as density. A bottling inerting make-up/vented gas is not this retained propellant supply. No liquid-N2/vaporization route, gas charge, pressure or gas-to-liquid volume ratio is presumed.

Purchased aerosol dispensing valve (valve)

One actually supplied valve assembly including its dip tube, mounting cup and seals when supplied together; describe its metal/polymer/elastomer bill of materials and upstream assembly. Do not count constituent procurement a second time. This conventional valve is not a bag-on-valve; a bag requires a distinct material and pressure-boundary review.

• Selected flow: Aerosol dispensing valve assembly
• Flow property / unit: Mass 93a60a56-a3c8-11da-a746-0800200b9a66 / kg

Purchased spray actuator (actuator)

Record this separately purchased moulded actuator with actual resin/additives, mass and manufacture. It is not included in valve mass for this route. A different polymer or inseparable supplied article requires a corrected identity and procurement ledger.

• Selected flow: Polypropylene aerosol actuator

One separately supplied moulded PP cap, actual mass/composition and upstream manufacture. Record rejects and inventory movement; no assumed piece mass or shared resin procurement.

• Selected flow: Polypropylene aerosol overcap
• Flow property / unit: Mass 93a60a56-a3c8-11da-a746-0800200b9a66 / kg

Corrugated shipping carton (carton)

Actual single shipping carton, including integral printing and closure supplied as part of that article; match fibre composition and converting burden. Separately purchased tape, pallet, label or stretch film needs its own atomic card when used; never hide them in carton mass.

• Selected flow: Printed corrugated fibreboard shipping carton
• Flow property / unit: Mass 93a60a56-a3c8-11da-a746-0800200b9a66 / kg

Use separately metered purchased ion-exchange/RO DI water only, subject to the complete native limitations stated in formulation_water: Product/Mass, CAS7732-18-5, plant production mix, no fixed quality standard/geography; comment also mentions distillation and consumer supply. Include actual washing and pressure/leak-test water makeup and losses; internal recirculation is not another purchase. A different actual water quality needs a separate corrected exchange.

Site electricity (electricity)

Meter blending, pumping, ventilation, compressed-air generation, pressure/testing, cleaning, laboratory, holding and handling with reconciled shared services. Native <1kV grid-average consumption candidate explicitly has locationOfSupply CN; leave this row unbound for an unspecified actual location/voltage/mix rather than imposing those conditions. Compressor electricity is counted here when compressed air is generated onsite, not again as purchased compressed air.

Outputs

Product flows

First quality-released filled aerosol contents (finished_aerosol)

Native Product/Mass, manufactured finished product, production mix at plant; no CAS, recipe, phase, grade, geography or locationOfSupply is specified and reference Mass factor is1. The binding is conditional identity for this measured finished aerosol, not a recipe, provider, pressure rating or deodorization performance. Q includes all net formulation and retained nitrogen at first quality release and excludes every packaging tare. Packaging burdens remain included. The generic UUID also does not make a bulk intermediate a second terminal reference.

Waste flows

Rejected bulk liquid removed for treatment (liquid_residue)

One actual segregated bulk liquid waste stream, net whole-mixture mass, complete composition and receiving treatment interface. Exclude internal rework until it actually leaves; whole waste mass and separately assayed constituent contents are not additive waste exchanges.

Collected washing effluent (wash_effluent)

Actual separately collected wash/test drainage sent to offsite treatment, with carrier water, dissolved chemicals and solids characterized. Do not also claim the same contained species as direct water emissions. Onsite treatment requires a complete added treatment inventory and separately measured final species/medium.

Rejected intact aerosol can transferred to treatment (rejected_filled_can)

One intact discarded physical article, including its measured retained contents and container, only where transferred intact. Keep tare/content/component subledgers. If onsite de-gassing or separation occurs, replace this intact handover with actual separately released gas, liquid and separated scrap streams and burdens; never record both whole article and its contained mass again.

Segregated carton rejects (carton_scrap)

Actual carton scrap separately weighed and transferred to its documented recipient. Recovery is not an automatic avoided-production credit; alternative separated packaging scrap requires additional actual atomic cards.

• Selected flow: Waste corrugated fibreboard carton
• Flow property / unit: Mass 93a60a56-a3c8-11da-a746-0800200b9a66 / kg

Elementary flows

Actual ethanol released to air (ethanol_air)

Record independently measured ethanol mass released after actual capture, including fugitive transfer and rejected/testing sprays. Identify actual air subcompartment and fossil/biogenic origin if the characterization requires it. Total VOC, COD and closure residual do not identify ethanol. Do not count captured liquid here.

• Selected flow: Ethanol, air emission

Actual DPnP released to air (dpnp_air)

Use independently supported DPnP species mass and air medium; no DPM/DPG surrogate or residual allocation. Actual perfume constituents released to air each require an additional chemically specific card after supplier/species identification; a generic fragrance-emission bundle is prohibited. No absence of those species is inferred from this representative list.

Actual nitrogen vented to air (nitrogen_air)

Measure actual nitrogen-only purge/charging/test losses with independent gas composition and conditions; retained propellant remains in Q. Ambient air passed through onsite pneumatics is not all nitrogen propellant loss; disclose its separately metered physical passage and treat any actual lubricant aerosol as its own species. A product-N2 UUID is not an elementary-air UUID.

7. Allocation and Co-product Handling

rule_id	applies_to	rule	source_ids
allocation_direct	all inventory rows	Use direct cohort/batch metering first. Allocate only genuinely shared burdens by measured causal drivers, with totals, driver units and reconciliation disclosed. No default economic or mass percentage is provided.
allocation_returns	aerosol	Failed and zero-output runs, rework and returns retain their actual burdens. Internal recovery is not external co-production; reaccepting an already released lot creates no new Q. Waste recovery has no automatic avoided-product credit. Document any real co-product separately with its actual physical mass, fate and allocation.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
period_normalization	all inventory rows	Convert and attribute the complete raw-period numerator of each exchange; divide once by positive Q defined only by first production-quality release in cp_release. Carry opening WIP burdens in and documented closing unreleased WIP burdens out. Retain failures, zero-output runs, all rework/returns and matched actual testing, packaging, storage, handling/dispatch burdens. Q is not deliveries; closing released finished goods of Q are not another production output or another closing production-WIP subtraction. A separate warehouse ledger cancels internal handover on consolidation and retains matching burdens without renormalizing already normalized factors. Q=0 preserves the full raw/burden pool without a normalized result.	cp_material; cp_packaging; cp_services; cp_release; cp_losses	Exchange amount per 1 kg reference flow
raw_conversion	all inventory rows	Use calibrated mass or independently evidenced volume times density at matched composition and conditions; convert pieces using actual measured article mass. Integrate rate times actual duration only for rate records. An integrated gas/liquid volume receives concentration or justified density conversion, no extra time factor. No native factor1.25 or secondary coefficient is a measured density.	cp_material; cp_packaging; cp_services; cp_losses	Converted raw quantities before normalization
mixture_subledger	ethanol; fragrance; dpnp; nitrogen	Constituent mass equals complete supplied commercial input mass times its compatible independently assayed mass fraction. Carrier water, solvents and impurities reconcile within that input, not another purchase. Do not treat v/v as w/w. Retained nitrogen is part of net product contents; total gas charged also includes measured losses.	cp_material; cp_release	Non-additive constituent ledger
physical_balance	all inventory rows	Maintain separate formulation/propellant, packaging and utility/ambient-air physical ledgers and independent elemental/water subledgers. Production charges plus opening unreleased WIP equal Q plus closing unreleased WIP, actual wastes/emissions and documented net transfers; net contents exclude packaging, so reconcile packaging to accepted-product tare and actual scrap separately. For an intact rejected filled can, only its separately measured contents enter the formulation/propellant ledger and its tare enters the packaging ledger; neither is added again beside the whole waste exchange. Internal recirculation cancels. Finished-stock warehouse balance is separate and must not add Q closing stock twice. Physical mixing/gas dissolution establishes no reaction yield or reaction water. Any actual chemistry or species/water formation/consumption needs independent evidence, never COD or fitting two unknown outlets to one residual.	cp_material; cp_packaging; cp_services; cp_release; cp_losses	Independent physical elemental water and species ledgers

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
identity	all inventory rows	Retain complete native names, route/grade/form, geography and property/unit restrictions in actual dataset matching. Ordinary auxiliary UUID/provider gaps require later verified binding, not surrogate chemicals or zero burdens.	Full native records; supplier certificates; provider applicability
period	all inventory rows	Complete matched periods and positive unique Q; trace failed batches, returns, opening/closing WIP and every carried burden. Distinguish first release from actual net delivery and do not discard real warehouse/dispatch burdens.	Cohort genealogy; full raw ledgers; warehouse reconciliation
actual_product	reference product	Qualify actual formula, phase stability, can/valve compatibility, net contents and actual pressure/leak/release criteria using responsible laboratory/quality owners. Patent or equipment examples do not establish a real site recipe, certified safety or fragrance/disinfection function.	Actual validated tests; composition; container specifications

9. Validation Rules

rule_id	applies_to	rule	source_ids
validate_reference	finished_aerosol	Require the unique terminal Product output finished_aerosol to match reference UUID, Mass/kg and net contents at first quality release in both languages. An intermediate sharing a generic UUID remains visible and cannot be renamed or hidden to evade selection.
validate_full_period	all inventory rows	Check complete raw attribution, WIP/finished-stock distinction, carried burdens, failure/rework and one normalization; check physical/element/water balances independently from species. Unknown emissions or missing operations remain findings, never fitted residuals or assumed zero.
validate_scope	reference product	Confirm actual nitrogen conventional-pressure route and packaging. No area, lifetime, dose, disinfectant efficacy, purification service, recipe/operating default or universal full-leaf mapping follows from kg production.	ep3481439-aerosol; zigler-nitrogen-filling

This selected nitrogen/tinplate route is a bounded synthesis of those choices, not a reported factory recipe or demonstrated site. No percentages, pressure, volume ratio, particle size, duration, yield, energy, corrosion inhibitor dose, performance or legal approval is adopted. The optional inhibitor is not presumed; actual use requires its specific extra exchange.

CO2/BOV compatibility is not adopted as the selected product. No capacity, fill pressure, air consumption, temperature or supply specification becomes an LCI default; actual onsite air-compression and test loads require measurement.
