  • Aliphatic solvents
  • CAS 110-54-3
  • IUPAC: n-Hexane

Hexane (n-Hexane) (CAS 110-54-3) appears in 7 of the 2,039 car-care products CarCareTruth tracks (as of July 2026), 7 of which carry a DANGER signal word on their published Safety Data Sheet. It is listed on California's Proposition 65 and classified as a VOC.

GHS H361 (reproductive toxicity Cat 2 — suspected of damaging fertility or the unborn child). California Prop 65 listed for male reproductive harm. Chronic inhalation can cause peripheral neuropathy. Very low flash point (−22°C) — extremely flammable. Use with adequate ventilation.

n-Hexane is a light aliphatic hydrocarbon solvent (C6) used in aerosol degreasers and cleaning products for its fast evaporation and low residue. It is a component of naphtha and petroleum distillate fractions. The primary health concern is chronic peripheral neuropathy from repeated inhalation and its reproductive toxicity classification (H361, Prop 65 listed). Flash point of −22°C makes it highly flammable.
