About this ingredient

Diacetyl is a naturally occurring organic compound (2,3-butanedione) used in cosmetics and flavoring applications. In cosmetic formulations, it functions as a fragrance component and flavoring agent, contributing buttery or creamy aromatic notes. It has been historically used in personal care products but has faced regulatory scrutiny due to respiratory health concerns.
