About

An aromatic fatty alcohol used as a fragrance ingredient and solvent in cosmetic formulations. Generally regarded as safe in low concentrations but may act as a mild skin sensitiser at high doses.

Phenylpentanol (also known as 5-phenyl-1-pentanol) is an aromatic alcohol that functions as a fragrance raw material and solvent in cosmetic products. It is not subject to specific EU restriction under Annex III or IV of Regulation 1223/2009, but like all fragrance substances it is covered by the general requirement that products must be safe. The IFRA standards recommend limits on its use due to mild sensitisation potential at high concentrations.

Skin benefits

  • Acts as an effective solvent for fragrance oils and active ingredients
  • Contributes to the sensory profile of cosmetic products

Known concerns

  • Mild skin sensitisation potential at elevated concentrations
  • Fragrance allergen labelling may apply under EU Cosmetics Regulation
