About

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

Cyclopentadecenone is a macrocyclic ketone with a 15-carbon ring containing one double bond, providing a musky, slightly ambrette and animalic fragrance. The macrocyclic ketone structure is one of the safer fragrance families with minimal sensitization and phototoxicity concerns. The natural product Exaltone (from deer musk) has the same carbon skeleton. The double bond introduces slight polarity.

Skin benefits

Known concerns

  • Limited specific toxicological data publicly available for this compound
  • Environmental persistence of some macrocyclic musks is a regulatory concern in the EU
