Hexadecalactone is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.

Hexadecalactone (also called omega-hexadecalactone or 16-hexadecalactone) is a macrocyclic lactone with 16 carbon atoms in the ring. It occurs naturally in some plant species and is used in perfumery and cosmetics as a fragrance ingredient, contributing a sweet, coconut-like odor. It is listed in the EU Cosmetics Ingredient Database (Cosing) and is not subject to specific restrictions under Annex III of EU Regulation 1223/2009. Like many lactones, it may cause mild skin sensitization in susceptible individuals at high concentrations.
