About

Propyl Alcohol is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

1-Propanol (propyl alcohol) is listed in EU Annex III of Regulation EC 1223/2009 with a maximum concentration limit, as it is a skin and eye irritant and has inhalation toxicity concerns in cosmetic aerosol formulations. It is restricted to 5% in cosmetic products (as denaturant) and must not be used in aerosol sprays. Its moderate score reflects both its irritancy and the EU concentration cap.

Skin benefits

  • Acts as an effective solvent for active ingredients
  • Reduces viscosity in formulations
  • Has antimicrobial preservation support properties

Known concerns

  • Skin and eye irritant at high concentrations
  • Restricted in aerosol cosmetic formulations in the EU
  • Can cause dryness with repeated topical use
