This record confirms an official common ingredient name for EU cosmetic product labelling. It does not by itself confirm that the substance is permitted, unrestricted or safe.
Global evidence snapshot
The resolved identity has matching regulatory evidence in 9 of 13 indexed market datasets: 8 country records and 1 EU Annex records. Every result and evidence gap is listed below.
A missing local match is not permission, approval or proof of safety. It means no strong identity match was resolved in that indexed dataset.

- Health Effects: Hexane mainly affects the nervous system. It causes degeneration of the peripheral nervous system (and eventually the central nervous system), starting with damage to the nerve axons.

- Toxicity Summary: IDENTIFICATION: n-Hexane is a straight chain saturated hydrocarbon obtained from certain petroleum fractions after various thermal or catalytic cracking steps. Commercial hexane may contain from 20%-85& n-Hexane and various amounts of hexane isomer, 2-methylpentane, 3-methylpentane, 2-3-dimethylbutene, cyclopentane, cyclohexane and small quantities of pentane and heptane isomers, acetone, methyl ethyl ketone, dichloromethane and trichloroethylene. Trace amounts of benzene may be present. N-Hexane is a colorless liquid and solubility in water is low. It is miscible with alcohol, chloroform and ether. Main uses are: rubber and adhesive solvent in shoe factories; extraction of soybean oil, callous seed oil and flaxseed oil. It is used in the pharmaceutical and cosmetic industries and is a cleaning agent for textiles, furniture and leather products. N-Hexane is also used for: determination of the refractive index of minerals, filling for thermometers and denaturant. HUMAN EXPOSURE: The target organs are: central nervous system and peripheral nervous system, respiratory system, heart, skin and eyes. Chemical pneumonia can occur after ingestion and and aspiration to the lungs. CNS depres Source: Hazardous Substances Data Bank (HSDB)
- Toxicity Summary: Hexane's toxicity is caused by it neurotoxic metabolite, 2,5-hexanedione. It damages the central and peripheral nervous system by causing axonal swelling and degeneration. 2,5-Hexanedione also reacts with lysine side-chain amino groups in axonal cytoskeletal proteins to form pyrroles. This results in neurofilament cross-linking and loss of function. (L175) Source: Toxin and Toxin Target Database (T3DB)
- Environmental Bioconcentration: An estimated BCF of 170 was calculated in fish for n-hexane(SRC), using a log Kow of 3.90(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC), provided the compound is not metabolized by the organism(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 130(SRC), determined from a structure estimation method(2), indicates that n-hexane is expected to have high mobility in soil(SRC). Volatilization of n-hexane from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.80 atm-cu m/mole(SRC), based upon its vapor pressure, 153 mm Hg(3), and water solubility, 9.5 mg/L(4). n-Hexane is expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(3). Utilizing the Japanese MITI test, 100% of the Theoretical BOD was reached in 4 weeks(5) suggesting that biodegradation is an important environmental fate process in soil(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 130(SRC), determined from a structure estimation method(2), indicates that n-hexane is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 1.80 atm-cu m/mole(SRC), derived from its vapor pressure, 153 mm Hg(4), and water solubility, 9.6 mg/L(5). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 2.7 hours and 3.7 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 170(SRC), from its log Kow of 3.90(7) and a regression-derived equation(8), suggests the potential for bioconcentration in aquatic organisms is high, provided the compound is not metabolized by the organism(SRC). Utilizing the Japanese MITI test, 100% of the Theoretical BOD was reached in 4 weeks(9) suggesting that biodegradation is an important environmental fate process in water(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), n-hexane, which has a vapor pressure of 153 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase n-hexane is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 24 hours(SRC), calculated from its rate constant of 5.61X10-12 cu cm/molecule-sec at 25 °C(3). n-Hexane does not contain chromophores that absorb at wavelengths >290 nm(4) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC).

- Uses: Pure n-hexane is used in laboratories. Most of the n-hexane used in industry is mixed with similar chemicals called solvents. The major use for solvents containing n-hexane is to extract vegetable oils from crops such as soybeans. These solvents are also used as cleaning agents in the printing, textile, furniture, and shoemaking industries. Certain kinds of special glues used in the roofing and shoe and leather industries also contain n-hexane. Several consumer products contain n-hexane, such as gasoline, quick-drying glues used in various hobbies, and rubber cement. (L175) Source: Toxin and Toxin Target Database (T3DB)

1. Confirm identity
Match the supplier specification, CAS/EC identifiers and composition to this official label name. Similar wording is not proof of chemical equivalence.
2. Review restrictions
Check every exact Annex record shown above, plus CMR, nanomaterial, SCCS and later-amendment requirements that may apply.
3. Verify the formula
Evaluate concentration, product type, purity, warnings, claims and each target market before making a compliance decision.
