About

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

Phenylisohexanol (also known as 3-methyl-5-phenylpentanol or 4-phenyl-2-butanol depending on isomer) is a synthetic aromatic alcohol used as a fragrance ingredient and perfumery fixative. It is listed in the IFRA Standards and the EU cosmetics fragrance database. No major GHS hazard statements are listed in the source data, though like many aromatic alcohols it carries a theoretical sensitisation risk at high concentrations. It is not restricted in EU Annexes and is considered safe at normal fragrance use levels. It must be identified in the INCI list as a fragrance compound under EU labelling requirements.

Skin benefits

  • Functions as a fragrance fixative enhancing product substantivity
  • Contributes to pleasant aromatic profile of cosmetic products

Known concerns

  • Theoretical skin sensitisation potential at high concentrations
  • Fragrance allergen — declarable on INCI label under EU Regulation 1223/2009
  • IFRA guidelines apply to maximum use concentration
