Benzyl Alcohol

  • Aromatic solvents
  • CAS 100-51-0
  • IUPAC: phenylmethanol

Benzyl Alcohol (CAS 100-51-0) appears in 1 of the 1,812 car-care products CarCareTruth tracks (as of June 2026). It is classified as a VOC.

Benzyl alcohol carries H302 (harmful if swallowed) and H332 (harmful if inhaled) at concentrated levels. At typical cleaning product concentrations (usually under 1%) these risks are very low. H319 (eye irritation) can occur at higher concentrations. Not a skin sensitizer at typical concentrations, though it is listed as a potential EU fragrance allergen at higher doses. Not on California's Prop 65 list. Biodegrades readily in aerobic conditions.

Benzyl alcohol is an aromatic alcohol used as a co-solvent, mild preservative, and fragrance ingredient in cleaning products. It is biodegradable and generally considered lower hazard than chlorinated solvents or glycol ethers at typical use concentrations. At high concentrations (workplace exposure levels) it can cause headache and CNS effects via inhalation; at consumer product dilutions this risk is minimal. Listed as a potential EU fragrance allergen at concentrations above 0.001% in leave-on products and 0.01% in rinse-off products.

Regulatory status

  • Not CA Prop 65 listed
  • EU CLP: H302, H332 at concentrate; H319 possible at higher concentrations
  • EU fragrance allergen disclosure required above threshold concentrations
