Ingredient review
Cyclohexylethyl Crotonate
INCI: Cyclohexylethyl Crotonate
A synthetic fragrance ingredient that adds a pleasant scent but offers no skincare benefits; safe at low levels but may cause sensitivity in some individuals.
In plain English
Cyclohexylethyl Crotonate is a man-made chemical used to give products a nice smell. It doesn't moisturize, treat, or improve your skin—it's purely there for fragrance. Because it's used in tiny amounts, it's generally considered safe, but if you have very sensitive skin or a fragrance allergy, it could cause irritation.

What it is
A synthetic ester derived from crotonic acid and cyclohexylethanol, used exclusively as a fragrance ingredient in cosmetics.
