About

An unsaturated acyclic monoterpene acetate with a fresh, fruity, citrus-green fragrance; not EU restricted but the double bond raises theoretical oxidation and sensitization concerns.

Methyloctenyl acetate (specific isomer not fully defined in CosIng) is an unsaturated acyclic acetate ester providing a fresh, fruity, green fragrance profile. The presence of a carbon-carbon double bond creates a theoretical risk of autoxidation, forming skin-sensitizing oxidation products upon air exposure. While not listed in EU regulatory annexes with restrictions, IFRA guidelines for related unsaturated acetate esters recommend antioxidant protection and concentration limits.

Skin benefits

  • Fresh fruity citrus-green fragrance note

Known concerns

  • Unsaturated structure – theoretical oxidation/sensitization risk
  • Limited specific toxicological data
