About

Methanol is a cosmetic ingredient. Exercise caution due to limited available safety data.

Methanol is restricted under EU Annex III as a constituent of other substances or in mixtures at concentrations ≥0.1% by weight. It carries extensive hazard classifications including H225 (highly flammable), H301/H311/H331 (acute toxicity multiple routes), H370 (organ toxicity - optic nerve), H351 (carcinogenicity concern), H360 (reproductive toxicity), and H302/H319/H336. The specific restriction limits methanol in cosmetics to 5% calculated as a percentage of ethanol and isopropyl alcohol content.

Known concerns

  • Systemic toxicity (optic nerve - H370)
  • Acute toxicity multiple routes (H301, H311, H331)
  • Highly flammable (H225)
  • Reproductive toxicity concern (H360)
  • EU Annex III restriction (5% max relative to ethanol/isopropanol)
