Ingredient review
Dimethyl Phenethyl Butyrate
INCI: DIMETHYL PHENETHYL BUTYRATE
A synthetic fragrance ester that adds a pleasant scent but offers no skincare benefits; generally safe at low concentrations.
In plain English
Dimethyl Phenethyl Butyrate is a man-made chemical that smells nice—often described as sweet, floral, or fruity. It is added to products like lotions and perfumes just for the scent. It does not moisturize, treat skin issues, or improve skin health. Because it is a fragrance ingredient, it can sometimes cause irritation or allergic reactions in sensitive individuals, but at the tiny amounts used in cosmetics, it is considered safe for most people.
