Ethyl Ferulate
What is Ethyl Ferulate?
Ethyl ferulate is the ethyl ester of ferulic acid, a phenolic antioxidant abundant in plant sources like rice bran, oats, and wheat bran. Chemically known as ethyl 4-hydroxy-3-methoxycinnamate, it is a lipophilic compound soluble in oils and emollients. In cosmetics, it belongs to the antioxidant category and is commonly incorporated into oil-based products such as serums, creams, and lotions. It functions by neutralizing free radicals through hydrogen donation and metal chelation, which inhibits lipid peroxidation and oxidative degradation of ingredients like unsaturated oils and sensitive actives. This mechanism helps preserve product color, scent, and efficacy throughout storage and application, while also contributing to microbial stability in formulations.
