Steam-distilled Lavandula angustifolia flowering-top essential oil

1. Scope and Applicability

This method covers one identified Lavandula angustifolia Mill. flowering-top essential oil obtained by contact with separately generated steam, condensation, oil/water phase separation and physical filtration, followed by actual quality release and in-scope packing/handling/storage. The foreground starts with weighed harvested flowering tops and delivered steam at the distiller; cultivation, feedstock transport and steam generation retain their compatible upstream burdens. The material is the whole separated essential oil, not isolated linalool, linalyl acetate or a constructed constituent mixture. Species, cultivar, flower/leaf/stem proportions, fresh/wilted/frozen state and moisture must be declared. No plant-part substitution, industrial yield, therapeutic action, fragrance efficacy or scent duration is assumed.

Exclude lavandin and spike lavender, isolated leaf/corolla/calyx oils, citrus expression, immersed-plant hydrodistillation, solvent extraction, resinoids/absolutes, downstream ethanol ultrasound extraction of residue, rectification/deterpenation and its terpene fractions, blending, diluted fragrance formulations and consumer perfume. An actual different route requires separate evidence and applicability assessment; CPC labels cannot merge it into this method.

Reference product flow	Terpenic oil 57b62a9e-51b2-4ea5-a51b-fc30d8cce064
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	species and cultivar; flower leaf stem proportions and harvested state; route and steam boundary; actual whole-oil identity and chromatographic test; actual residual water and solvent specifications; net mass tare and volume conversion temperature; first-release gate and unique Q; site and complete period; failed runs returns rework and samples; raw WIP finished stocks and carried exchange burdens; hydrolat leachate residue destinations and allocation; actual packaging warehouse handling dispatch scope; native classification debt and provider compatibility

The selected Product identity is Terpenic oil, Production mix, at plant. Its route and name-property components are empty; CAS, formula, species, grade, medium and geography/locationOfSupply are unspecified. The comment describes plant-derived terpene-rich essential oil. Only primary Mass, meanValue 1.0, is declared; this is not density, purity, yield, a supplier quantity or an LCI provider. Use this broad identity only with the actual whole-oil botanical/route/release qualifiers. It does not identify an isolated pure chemical or a deterpenation by-product. The native CPC35499 residual classification conflicts with the explicit essential-oil physical description and proposed35410 context; retain this classification debt for source-owner clarification. No explicit native route, fixed grade, CAS or geographic restriction contradicts this qualified oil. Do not infer approval or repair the native class silently.

Q is the positive net mass of uniquely identified whole oil first accepted and newly quality-released in the actual reporting cohort, excluding packaging tare and separately separated aqueous phase. It includes measured residual water retained within the accepted oil specification; do not substitute dry constituents, biomass, all condensate, sales or actual deliveries. A released lot returned, filtered and reaccepted is not newly produced Q. Keep its further burdens with its original cohort. Production outputs already include Q; do not add that same released closing finished stock as another output. Keep a separate finished-store/dispatch mass and burden ledger: opening finished stock plus production release and traced physical returns equals dispatch plus closing stock and actual loss, with return reversals linked. Cancel internal release handover when consolidating. Retain real packing, warehouse, handling/dispatch and rework burdens assigned to the same cohort; do not presume release equals delivery.

Declare every required qualifier in the concrete dataset or equivalent records; absence makes applicability incomplete.

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	1 kg net accepted whole oil at the first new quality-release gate; Q has the same scope as cp_acceptance and cp_stock, never all plant mass or all distillate.
liquid_conversion	liquid and steam ledgers	Mass	kg	Use calibrated net weighing or integrated volume times independently supported actual density at measured composition and temperature; steam mass conversion also requires its actual state. No volume/dry-weight yield as mass yield.
normalize_once	all inventory rows	Actual row property	row unit per 1 kg reference flow	Every collection protocol retains undivided actual-period measurements, including failed/zero-output runs, cleaning, returns/rework and raw-material/WIP/finished stock masses and their carried exchange burdens. Assign by genealogy and physical subdivision before allocation. For each exchange, A_i is the attributable converted numerator after opening-WIP carried burden and closing-WIP deferral, co-product attribution and matched in-scope finished-cohort burdens. Do not apply a WIP correction twice or subtract released finished stock from production Q. calc_normalize is the sole reporting division: A_i / Q. Its appearance on a card and in aggregation_rule denotes that same operation, never sequential division. A zero-output campaign has no stand-alone per-kg result; carry its burdens to the causally matched accepted cohort or disclose unresolved attribution.
water_and_species	phase ledgers	Mass	kg	Maintain separate physical total, water and actual species ledgers; no assumed reaction water from phase change. Oil density, GC relative area, COD and native meanValue are not substitutes for independent species mass evidence.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Weighed harvested Lavandula angustifolia flowering tops and delivered steam received at distiller; actual other inputs and upstream burdens retained
starting_condition_role	foreground_input
product_classification_scope	Qualified flowering-top whole-oil subset of CPC3.0:35410, proposed narrower scope; classification acceptance separate
recursive_input_rule	Purchased same-category oil carries its supplied mass and prior burdens; do not treat rebottling, return or reacceptance as new extraction. Any actually blended purchased oil changes this route and requires evidence reassessment.
upstream_dataset_requirement	Match actual harvested species/state/moisture, cultivation/transport, steam and packaging provider reference amounts, grade, geography and time. Generic identity does not establish provider compatibility.
disclosure	Disclose botanical and release gate, site/period, exact steam boundary, complete stocks/carried burdens, all water phases, secondary destinations, allocation and included storage/dispatch.

rule_id	applies_to	rule	source_ids
b_route	oil_production	Include receiving, any actual pre-distillation holding, steam contact, condenser cooling, separator operation, filtration, release tests, cleaning, pollution controls, actual packing/onsite storage/handling and in-scope dispatch activities, rejects and rework. Delivered steam generation is upstream; if generated onsite, expand the generator as a separate measured unit, replace the internal steam purchase, cancel internal steam transfer and include actual feedwater, fuel/electricity, blowdown and emissions once. No equipment setting or laboratory scale is a factory default.	wilson-lavender-2021
b_phases	water and oil ledgers	Separate direct-contact steam mass/enthalpy, inherent plant water, cooling-circuit makeup/return, cleaning water, gross condensed distillate, separated oil, hydrolat, bottom leachate, wet spent biomass, vapour and actual releases. Condensed steam is water transferred internally, not new oil or new purchased water. Closed cooling circulation is not fresh abstraction. Internal recycled hydrolat/condensate cancels when consolidated; record makeup, purge and real losses. Distinguish oil dissolved/dispersed in each aqueous stream from accepted oil.	turrini-lavender-2021
b_stock	all inventory rows	Q is the positive net mass of uniquely identified whole oil first accepted and newly quality-released in the actual reporting cohort, excluding packaging tare and separately separated aqueous phase. It includes measured residual water retained within the accepted oil specification; do not substitute dry constituents, biomass, all condensate, sales or actual deliveries. A released lot returned, filtered and reaccepted is not newly produced Q. Keep its further burdens with its original cohort. Production outputs already include Q; do not add that same released closing finished stock as another output. Keep a separate finished-store/dispatch mass and burden ledger: opening finished stock plus production release and traced physical returns equals dispatch plus closing stock and actual loss, with return reversals linked. Cancel internal release handover when consolidating. Retain real packing, warehouse, handling/dispatch and rework burdens assigned to the same cohort; do not presume release equals delivery.
b_complete	all inventory rows	Whole purchased formulations, including their carrier water/solvent, enter procurement once; constituent assays are subledgers. This route uses actual plant material and steam, not a synthetic reconstruction from pure aromatic chemicals. Listed cards are not an exclusion list: add a separate atomic card for every actual extra cleaning chemical, fuel, refrigerant, package component, transport service, waste or elementary species/medium. No actual burden may be removed to fit the example. Distribution after the disclosed scope, consumer use and end of life remain separate stages.

7. Allocation and Co-product Handling

rule_id	applies_to	rule	source_ids
a_subdivide	oil and secondary outlets	Separate directly attributable filtration/packing/storage/testing burdens from joint distillation burdens first. Record hydrolat and spent biomass with their true destination and specification: sale as a qualified coproduct versus discarded waste are disjoint physical portions, never both the same mass. Residue ethanol extraction is a separate downstream process; no automatic credit for potential use.	turrini-lavender-2021
a_joint	joint burdens	Use a documented demonstrable causal physical relationship where it exists. Otherwise use actual contemporaneous net revenue shares of qualified oil and genuinely sold coproducts for residual joint burdens, with prices, quantities, time basis and sensitivity disclosed. No default coefficient, automatic hydrolat-water mass allocation or credit for disposal. Apply allocation only to burdens, not to the independent physical mass/species balance. If evidence cannot justify attribution, the concrete dataset remains incomplete.
a_once	all inventory rows	Every collection protocol retains undivided actual-period measurements, including failed/zero-output runs, cleaning, returns/rework and raw-material/WIP/finished stock masses and their carried exchange burdens. Assign by genealogy and physical subdivision before allocation. For each exchange, A_i is the attributable converted numerator after opening-WIP carried burden and closing-WIP deferral, co-product attribution and matched in-scope finished-cohort burdens. Do not apply a WIP correction twice or subtract released finished stock from production Q. calc_normalize is the sole reporting division: A_i / Q. Its appearance on a card and in aggregation_rule denotes that same operation, never sequential division. A zero-output campaign has no stand-alone per-kg result; carry its burdens to the causally matched accepted cohort or disclose unresolved attribution.

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
calc_convert	all inventory rows	Convert raw measurements to their actual numerator unit before attribution. Liquid mass = integrated volume times actual composition/temperature-matched density. Integrate rate over actual duration only when it is a rate. Preserve steam state/enthalpy and independently measured phase/species amounts; no default yield or second duration multiplier.	cp_material; cp_utility; cp_water; cp_residual	converted raw ledger
calc_attribute	all inventory rows	For each exchange, construct A_i from complete converted matched-period burdens plus attributable opening-WIP carried burdens minus closing-WIP deferred burdens, with physical subdivision and justified residual joint allocation, and actual in-scope finished-cohort packing/storage/handling burdens. Track old released returns/rework with the original cohort; reconcile separate finished mass/burden ledger and cancel internal transfers. Do not add released closing finished stock as production output. Physical outlet A_i retains its actual matched mass; burden allocation does not reduce or duplicate that physical outlet ledger.	cp_stock; cp_material; cp_utility; cp_water; cp_finishing; cp_residual	A_i
calc_normalize	all inventory rows	Report the attributable exchange amount per 1 kg reference flow as A_i / Q exactly once; Q is cp_acceptance unique positive newly released whole-oil net kg for the same cohort. The reference row is 1 kg. Card formulas and protocol aggregation point to this one operation, not repeated division.	A_i; Q; cp_acceptance; cp_stock	exchange amount per 1 kg reference flow
calc_physical	oil_production	Reconcile complete physical input mass plus opening process stock and real inward returns against actual outward oil/aqueous/solid/waste/emission masses plus closing process stock, preserving internal transfer cancellation and disjoint destinations. Newly released Q is a subset of unique accepted oil, not every oil re-transfer. Separately reconcile water and independently supported actual species/elements. No unknown reaction-water residual fitting.	cp_material; cp_water; cp_acceptance; cp_residual; cp_stock	independent physical water and species balance

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
q_identity	released_oil	Verify real species/part/cultivar and supplied oil state, actual test methods, residual water and solvent limits, grade and batch identity; no source default or molecular substitute.	cp_material; cp_acceptance
q_complete	all inventory rows	No missing failed runs, zero-output burdens, samples, WIP/stock carry or actual included warehouse/packaging/handling/rework. Keep uncertainty and unresolved attribution explicit.	cp_stock; cp_finishing
q_source	source applicability	Use the two studies for their verified botanical/physical route and stream distinction only. Utah frozen laboratory material and Italian Rosa residue work do not establish present industrial quantities or geography. Wilson Table2 mass ratio and printed inverted sentence conflict; no yield default is taken.	wilson-lavender-2021; turrini-lavender-2021
q_provider	unbound auxiliaries	Resolve each actual auxiliary and elementary species/medium before dataset finalization; retain blank UUID rather than adopting a contrary route/grade. Native broad identity is not a provider LCI amount.	supplier and environmental primary records

9. Validation Rules

rule_id	applies_to	rule	source_ids
v_identity	released_oil	Require exact species/part/route/state and full actual oil identity and acceptance records; verify generic Product UUID compatibility separately from provider quantities, grade and geography. The unique reference_flow_link must select released_oil in both languages with the same UUID. Auxiliary UUID/provider gaps require disclosure and later binding, not fabricated identities.
v_cohort	all inventory rows	Q must be positive unique first-release whole-oil net mass of the matched cohort. Include all failed runs, rework, WIP carry and real storage/packing/handling loads; trace zero-output burdens. Production and warehouse balances must reconcile without counting released closing finished stock twice or a return as new production. Any unavailable actual required record leaves the concrete dataset incomplete.
v_physical	physical and species ledgers	Close total physical mass with measured inputs, water phases, oil, all outputs and stock changes before allocation; independently verify actual molecular species and supported elemental balances. Steam condensation, evaporation and water redistribution are phase changes, not net reaction-water production. Do not infer a reaction-water term, missing VOC or second unknown outlet from the same closure residual; disclose uncertainty and investigated losses. No oil amount from COD, GC-area conversion, assumed extraction yield or biomass remainder.
v_dimension	all inventory rows	Normalize only once using calc_normalize after raw conversions, attribution and stock burdens. Volumes require actual independently supported composition/temperature-matched density; a native secondary coefficient is not density. Hydrolat, leachate, oil and cooling return remain separate. Each waste transfer, direct release and coproduct portion must have one physical destination and no duplicate mass.
