About

A bridged tricyclic sesquiterpene acetate fragrance ingredient classified as a skin sensitiser (H317) under EU GHS — IFRA restrictions apply.

Trimethytricyclododecanyl Acetate (or 1,3,3-trimethyl-2-norbornanyl acetate) is a sesquiterpene acetate derived from the reaction of trimethyltricyclodecanol with acetic anhydride. Its H317 classification (may cause allergic skin reaction) reflects the norbornane sesquiterpene scaffold, which has been associated with contact allergy in fragrance sensitisation studies. Listed in EU CosIng, IFRA restrictions apply, limiting its concentration in consumer products. At the restricted use levels, the risk of sensitisation is acceptable.
