Fragrance material review on ω-pentadecalactone

A toxicologic and dermatologic review of ω-pentadecalactone when used as a fragrance ingredient is presented. ω-Pentadecalactone is a member of the fragrance structural group macrocyclic lactone and lactide derivatives. The fragrance ingredient described herein is one of 12 structurally diverse C14, C15, and C16 compounds that include (7) saturated mono-and (2) saturated di-ester lactones and (3) unsaturated lactones. For the latter, the double bond is not adjacent to (in conjugation with) the ester group. This review contains a detailed summary of all available toxicology and dermatology papers that are related to ω-pentadecalactone and is not intended as a stand-alone document. Available data were evaluated, then summarized, and includes: physical properties; acute toxicity; skin irritation; mucous membrane (eye) irritation; skin sensitization; elicitation; phototoxicity; repeated dose; and genotoxicity data. A safety assessment of macrocyclic lactone and lactide derivatives will be published simultaneously with this document. Please refer to Belsito et al. (2011) for an overall assessment of the safe use of this material and all macrocyclic lactone and lactide derivatives in fragrances.
