About

4-methylen-2,6-epoxydecane is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

This compound is a decane-derived cyclic terpene containing both an exocyclic methylene double bond and an internal epoxide. Such bifunctional terpenes can be reactive (Michael acceptor potential from the methylene group, epoxide reactivity). It is not specifically listed in EU cosmetics annexes, but the IFRA guidelines and EU fragrance allergen framework may apply. Requires further safety data evaluation.
