Start nowTechnical hexane / n-hexane · CAS 110-54-3
Technical hexane helps pull oil from crushed seeds. Heat then recovers most of the solvent for reuse.
The unresolved question is what remains in food and how much reaches consumers.
Traces have been detected, and EU law sets maximum residues for oils, cocoa butter and some defatted ingredients. EFSA has also modelled potential dietary exposure using legal maximum residue limits. Some high-percentile estimates for infants, toddlers and other children exceeded the exposure previously assumed by the SCF. Representative occurrence data are still needed to estimate what consumers are actually exposed to.
EFSA's Food Contact Materials, Enzymes and Processing Aids Panel — the FCM Panel — is reassessing technical hexane. Meanwhile, ECHA added n-hexane to the Candidate List. The Candidate List is REACH's list of substances of very high concern that can trigger supply-chain duties. A French bill proposes warnings, testing and substitution measures, while a General Court case challenges the Candidate List decision. EFSA's mandate deadline is 22 November 2027.
01Identity
Technical hexane is the commercial solvent mixture used in extraction. EU food rules define it mainly by a 64–70°C distillation range and set limits for residues left in particular foods. n-Hexane is one component of that mixture. REACH identifies it as a defined substance because of its intrinsic hazard — what the substance can do — after repeated exposure. The five acyclic C6H14 isomers in the hero illustrate the molecular family; commercial grades can also contain other hydrocarbons and impurities.
Commercial mixture · distillation range · permitted uses · food residues
CAS 110-54-3 · repeated-exposure hazard · supply-chain duties
The legal definition uses a distillation range and leaves component percentages unspecified.
Candidate List status applies to n-hexane as a defined substance. Food-residue safety follows a separate legal and evidence framework.
EFSA is seeking batch composition, impurities and information on fresh and recycled solvent because food legislation leaves the mixture’s component fractions unspecified.
Commercial grades
One commercial grade; European supply remains unsurveyed.
One supplier grade; composition ranges vary across suppliers and batches.
02Routes
An exposure route is the path a substance takes from its source to a person. One extraction process creates three different routes, and the evidence for one route cannot answer the others.
Four retail oils in one 2021 Malaysian method study. The results provide a method signal; a European market estimate requires representative sampling.
Signals too low to measure reliably were more frequent after the hexane-meal diet in a six-cow analytical subset. This is preliminary evidence; transfer magnitude and consumer exposure cannot be estimated.
NIOSH eight-hour recommended limit. Repeated inhalation can cause peripheral neuropathy.
Industry-level estimates in a parliamentary report; recovery varies by plant and process.
Four individual products from one Malaysian market, analysed chiefly to validate a method. Product provenance and refining history were not reported; low-level validation and ambient or procedural contamination controls limit interpretation. The values are illustrative analytical observations, not prevalence estimates. European exposure requires representative occurrence and consumption data.
One pooled milk sample per cow in a six-cow analytical subset of the extreme diets. The study reported no quantified milk concentrations and does not quantify transfer magnitude or consumer exposure. Trace-level method and contamination controls were limited, and health significance remains unresolved.
A dietary-residue threshold requires route-specific oral-exposure evidence.
03Evidence
Evidence at a glance
| Question | What the evidence shows | What remains unknown |
|---|---|---|
| What remains in food? | Small studies have detected residues in individual oils. EU law sets food-specific maximum residue levels. | Representative public European occurrence data — measurements across enough foods, places and times to estimate consumer exposure. |
| Can residues move from feed to milk? | A six-cow analytical subset — the smaller group whose samples were analysed — produced preliminary signals below the quantification limit, the level above which the method can report a reliable amount. | A quantified transfer rate, representative occurrence, consumer exposure or health significance. |
| What is established for workers? | Repeated inhalation of n-hexane in workplace air can damage peripheral nerves, and occupational air limits exist. | This evidence does not answer the separate question of dietary exposure from residues in food. |
| What mixture enters the plant? | Supplier records show that the n-hexane fraction varies between commercial grades. | A representative European picture of fresh and recycled technical-hexane composition and impurities. |
EFSA’s data calls closed on 30 June 2026; publication of submitted records and the final assessment remains pending.

Four retail oils · Malaysia · 2021
Four individual products from one Malaysian market, analysed chiefly to validate a method. Product provenance and refining history were not reported; low-level validation and ambient or procedural contamination controls limit interpretation. The values are illustrative analytical observations, not prevalence estimates. European exposure requires representative occurrence and consumption data.
Method sensitivity is part of the finding and limits comparison across studies.
Older national retail sampling provides historical context. Current European occurrence requires new representative data.
EFSA's submission window closed on 30 June. Validation and acceptance for the broader ChemMon collection closes on 31 August. The resulting hexane records and an occurrence-based exposure assessment remain unpublished.
Upper scenarios use maximum-residue assumptions and model dietary intake.
The submission window is closed; publication of the resulting dataset and conclusion remains pending.
This date closes data processing for the annual occurrence call. The opinion and publication follow separate timetables.
Repeated occupational inhalation can cause peripheral neuropathy. NIOSH names numb extremities and muscle weakness.
Workplace air limits
EFSA has modelled potential exposure from legal maximum residues. Estimating actual dietary exposure still needs representative occurrence, consumption and dose evidence for the relevant mixture.
A dietary-residue threshold requires route-specific oral-exposure evidence.
These limits govern workplace air. Food safety uses separate residue and dietary-exposure evidence.
04Regulation
Current EU food law
Directive 2009/32/EC sets maximum hexane residues of 1 mg/kg in extracted fats, oils and cocoa butter; 10 mg/kg in food containing defatted protein products or flour; 30 mg/kg in defatted soya sold to consumers; and 5 mg/kg in defatted cereal germs.
Five regulatory files
| File | What it sees | Status | Decision ahead |
|---|---|---|---|
| Extraction Solvents Directive | Technical mixture + food residue | Binding | Retain, revise or narrow uses and limits |
| EFSA reassessment | FCM Panel · composition + hazard + diet | Under review | Can current uses be supported? |
| REACH Candidate List | n-Hexane’s repeated-exposure hazard | Binding | Supply-chain duties; possible later authorisation |
| French bill no. 3023 | Disclosure + testing + substitution | Proposed | Will warnings and records become law? |
| Occupational safety | Worker inhalation | Established | Control vapour and reduce exposure |
EFSA reassessment
Composition records describe what enters the plant. Occurrence data are measurements of what remains in foods across a defined sample. Consumption data then connect those measurements to consumer exposure — the amount people may take in through what they eat.
These inputs are needed to connect the material used in plants to consumer exposure.
Safety demonstration
The reassessment needs a defensible toxicological reference point for the material used, followed by representative occurrence and consumption data to test consumer exposure against it. Codex says the supplier or user should demonstrate processing-aid safety. EU food law makes operators responsible for ensuring and verifying that food under their control is safe and compliant.
The regulation establishes safety and operator-responsibility duties. It does not prescribe a universal processing-aid dossier or place an exclusive burden on the solvent supplier.
Codex is an international guideline. Its supplier-or-user wording does not create an exclusive EU-law burden on one party.
Each system answers permission, residue and disclosure differently. Population exposure still requires occurrence, consumption and dose evidence.
Federal rules expressly cover some uses, including spice oleoresins, hops and specified defatted cottonseed flour. EPA also regulates hexane-based oilseed extraction as an air-emissions source; that environmental rule does not authorise food use.
Hexane is listed for vegetable fats, oils and oilseed meals at 10 ppm, with separate limits for hops and natural extracts.
Hexanes may be used in all foods at 20 mg/kg. Ingredient statements may omit a compliant processing aid.
The use standard permits extraction during edible-fat and oil manufacture and requires removal before the final food is completed.
This narrow permission covers spice oleoresins and hops extract. The official-source review left the legal basis for routine oilseed extraction unresolved.
This permission is specific to the cottonseed products and specifications in 21 CFR 172.894. It is not a general authorisation for every oilseed or food use.
This EPA rule establishes an environmental emissions boundary and evidence of industrial practice. It does not authorise a food use or establish food safety.
The list also specifies different limits for hop extracts, pre-isomerised hop extract, natural extractives and spice extracts.
This broad all-food ceiling is a different regulatory architecture from the EU product-specific table.
The exemption covers ingredient declaration. Permission and residue compliance remain separate questions.
The official English standard states a removal condition and leaves a numerical general residue ceiling unspecified. A Japanese food-law specialist should check the translation and current legal application before publication.
JECFA supplies an international scientific benchmark; national law controls market permission. The official sources reviewed leave the next review undated as of 10 August 2026.
United States
Not automatically. It would not amend US law or invalidate a GRAS conclusion. The question is whether EFSA's underlying hazard and exposure evidence weakens the scientific basis or specifications for a particular US use. That question matters because EPA's IRIS assessment has no oral reference dose, while ATSDR's 2025 profile derived an intermediate oral screening value and found no chronic oral studies from which to derive one.
The standard applies to the particular substance, specifications and intended conditions of use. It is not a blanket FDA approval of technical hexane extraction.
The absence of an IRIS oral reference dose is an assessment gap, not evidence that a particular authorised food use is unsafe.
An ATSDR minimal risk level is a screening value for public-health assessment. It is not a food-law limit or an automatic finding on a GRAS conclusion.
French bill no. 3023
EU food-information law excludes residues from the ingredient definition and can permit substances used like processing aids to be omitted when the legal conditions are met.
French proposalMay contain hexane residues
Bill no. 3023 would add warnings, testing and records across food and feed pathways, backed by a proposed €75,000 penalty. Introduced on 7 July 2026, it remains before committee.
Application depends on the finished product and the legal role of the substance.
Introduced on 7 July 2026 and referred to committee; the text remains a proposal.
05Decision
Fixed dates, conditional dates and unscheduled decisions require different action. The first item is already due; the later rows are the forward watch.
The six-month article-notification point has passed. Companies should check the relevant 0.1% article threshold, one-tonne annual total, supply-chain communication, safety-data-sheet and SCIP conditions; not every duty applies to every product.
This closes validation for the broader 2026 ChemMon collection, which includes submitted hexane records. It is not a hexane opinion deadline.
The bill remains with the Social Affairs Committee. Rapporteur, hearing, debate and vote dates have not been announced.
Only the Article 2 contribution carries this proposed date, and only if Parliament enacts the bill. The date does not apply to every measure in the proposal.
The challenge seeks annulment of ECHA's SVHC decision and removal of n-hexane from the Candidate List. Hearing and judgment dates have not been announced.
The mandate covers technical-hexane composition, consumer exposure through food, toxicology and current residue limits. Adoption and publication can follow later.
The Commission can consider changes to permitted uses or residue limits after the scientific opinion. No response timetable has been announced.
Companies must check the applicable article concentration, annual tonnage, communication, safety-data-sheet and SCIP conditions. The duties do not apply identically to every company, mixture or article.
This date closes data processing for the annual occurrence call. The opinion and publication follow separate timetables.
The proposed 1 January 2027 commencement becomes operative only if Parliament enacts the bill.
The date applies only to the Article 2 contribution. It is not a commencement date for the bill's other proposed disclosure, testing or feed-information measures.
The case is pending; publication of a hearing or judgment date remains outstanding as of 10 August 2026.
The mandate deadline sets the timetable for the work. Adoption and publication may follow later.
The scientific opinion informs, but does not predetermine, any later decision on permitted uses or residue limits.
Industrial trials and organic production show that other routes exist. Neither establishes an easy, universal or €1 million conversion for conventional commodity plants.
EcoXtract partners reported 2-methyloxolane campaigns in an existing Crown hexane unit in 2021 and 2022. The public abstract confirms further modifications, but not their detailed scope, duration or cost.
EU organic rules list authorised processing aids. They specify ethanol for defined extraction uses but not technical hexane. That excludes deliberate hexane use in the relevant certified processes; it does not prove retrofit economics.
The project record establishes the participant, location and project period. It does not disclose a plant-conversion cost or detailed engineering scope.
This is an industry-authored conference abstract. It does not provide the detailed modifications, conversion duration or capital cost, and it is not independent proof of retrofit economics.
This is an organic-production boundary. It does not prohibit technical hexane across conventional EU food production.
The list supports the organic process restriction. It does not show that conventional commodity plants can convert easily or economically.
Substitution options
Removing hexane can shift yield, energy demand, capital cost and operating risk. The trade-offs vary by oilseed and plant. There is no simple switch that fits every crop, product and factory.
Avoids extraction-solvent residues and can suit premium or smaller-volume oils.
Recovery depends on the crop and press. More oil remains in the meal, so commodity-scale yield and economics can be weaker.
Performance varies by oilseed, pretreatment, press design and product specification.
Can work with several oilseeds and may recover polar compounds; renewable supply is possible.
Water management and solvent recovery can raise energy use and cost. Existing plants need process and safety changes.
Process-model estimates; values vary by plant, oilseed and operating conditions.
EU-authorised, bio-based production is possible, and some studies report yields close to hexane.
Full-scale commodity use remains limited. Cost, flammability, peroxide control, crop performance and higher modelled heat demand matter.
Driven by the modelled solvent-removal system, retention and water presence; operating values vary by plant and process.
Non-flammable and removed by depressurisation; useful where selective extraction can justify the process.
High-pressure equipment, capital cost and throughput can make it unsuitable for high-volume commodity oilseeds.
Commercial suitability depends on feedstock, required yield, co-products, throughput and capital cost.
Most of the solvent is recovered in the factory. The evidence still has to follow what remains through food, feed and workplace air.

Method sensitivity is part of the finding and limits comparison across studies.A 2005 Korean survey detected residual hexane in nine of 87 vegetable-oil samples bought on the local market.
Older national retail sampling provides historical context. Current European occurrence requires new representative data.Greenpeace France reported 0.04–0.08 mg/kg in selected refined oils and higher concentrations in selected oilseed meals.
Advocacy-commissioned, non-representative testing; industry challenged laboratory accreditation and interpretation.Controlled dairy-cow research reported n-hexane signals below the 10 ng/g quantification limit in five of six milk samples after the hexane-meal diet and one of six after the 2-methyloxolane-meal diet.
One pooled milk sample per cow in a six-cow analytical subset of the extreme diets. The study reported no quantified milk concentrations and does not quantify transfer magnitude or consumer exposure. Trace-level method and contamination controls were limited, and health significance remains unresolved.A representative public European dataset connecting commercial-solvent composition, food occurrence and consumer exposure is still missing.
EFSA’s data calls closed on 30 June 2026; publication of submitted records and the final assessment remains pending.EFSA’s screening scenarios estimated high-percentile exposure using foods at their legal maximum residue limits.
Upper scenarios use maximum-residue assumptions and model dietary intake.EFSA’s dedicated composition call and 2026 occurrence-data window closed on 30 June 2026.
The submission window is closed; publication of the resulting dataset and conclusion remains pending.Repeated occupational inhalation of n-hexane can cause peripheral neuropathy, including numb extremities and muscle weakness.
A dietary-residue threshold requires route-specific oral-exposure evidence.NIOSH recommends an eight-hour limit of 50 ppm; the current US federal OSHA limit shown by NIOSH is 500 ppm.
These limits govern workplace air. Food safety uses separate residue and dietary-exposure evidence.Directive 2009/32/EC sets maximum hexane residues of 1 mg/kg in extracted fats, oils and cocoa butter; 10 mg/kg in food containing defatted protein products or flour; 30 mg/kg in defatted soya sold to consumers; and 5 mg/kg in defatted cereal germs.
EU food-information law excludes residues from the ingredient definition and permits omission of substances used like processing aids where the Article 20 conditions are met.
Application depends on the finished product and the legal role of the substance.EU General Food Law requires food business operators to ensure and verify that food under their control meets the food-safety requirements relevant to their activities.
The regulation establishes safety and operator-responsibility duties. It does not prescribe a universal processing-aid dossier or place an exclusive burden on the solvent supplier.Codex says the supplier or user should demonstrate the safety of a processing aid, including unavoidable residues under good manufacturing practice.
Codex is an international guideline. Its supplier-or-user wording does not create an exclusive EU-law burden on one party.The reviewed US direct-food rule permits hexane residues from extracting spice oleoresins at no more than 25 ppm and hops extract at no more than 2.2% by weight.
This narrow permission covers spice oleoresins and hops extract. The official-source review left the legal basis for routine oilseed extraction unresolved.US food-additive rules permit n-hexane in the manufacture of specified defatted cottonseed flour, subject to composition requirements and a maximum residue of 60 ppm.
This permission is specific to the cottonseed products and specifications in 21 CFR 172.894. It is not a general authorisation for every oilseed or food use.US air-emissions rules recognise commercial hexane grades in solvent-extraction plants processing major oilseeds, including soybean, canola, sunflower and safflower.
This EPA rule establishes an environmental emissions boundary and evidence of industrial practice. It does not authorise a food use or establish food safety.A US GRAS conclusion based on scientific procedures requires general recognition among qualified experts and evidence of the same quantity and quality required for food-additive approval.
The standard applies to the particular substance, specifications and intended conditions of use. It is not a blanket FDA approval of technical hexane extraction.EPA's IRIS assessment for n-hexane does not provide an oral reference dose.
The absence of an IRIS oral reference dose is an assessment gap, not evidence that a particular authorised food use is unsafe.ATSDR's 2025 profile derived an intermediate-duration oral minimal risk level of 0.1 mg/kg/day and no chronic oral minimal risk level because it located no chronic oral studies.
An ATSDR minimal risk level is a screening value for public-health assessment. It is not a food-law limit or an automatic finding on a GRAS conclusion.Canada lists hexane as an extraction solvent for vegetable fats and oils and vegetable oilseed meals, with a maximum residue of 10 ppm, alongside separate permissions for hops and natural extracts.
The list also specifies different limits for hop extracts, pre-isomerised hop extract, natural extractives and spice extracts.Australia and New Zealand permit hexanes as an extraction-solvent processing aid in all foods at a maximum permitted level of 20 mg/kg.
This broad all-food ceiling is a different regulatory architecture from the EU product-specific table.Australia and New Zealand permit the ingredient statement to omit a substance used as a processing aid in accordance with Standard 1.3.3.
The exemption covers ingredient declaration. Permission and residue compliance remain separate questions.Japan's use standard permits hexane for extracting fats and oils during the manufacture of edible fats and oils and requires its removal before the final food is completed.
The official English standard states a removal condition and leaves a numerical general residue ceiling unspecified. A Japanese food-law specialist should check the translation and current legal application before publication.JECFA recommended re-evaluating hexanes because commercial composition and resulting residues might differ from the material covered by its earlier assessment.
