Ingredient review
Methyl Benzodioxepinone
INCI: METHYL BENZODIOXEPINONE
A synthetic fragrance ingredient that adds a pleasant scent but offers no skincare benefits; safe for most but may cause sensitivity in some.
In plain English
Methyl benzodioxepinone is a lab-made chemical used to give cosmetics a sweet, floral smell. It doesn't moisturize, treat, or improve your skin—it's purely for scent. While generally considered safe at low levels, it can be a potential irritant for people with very sensitive skin or fragrance allergies.

What it is
A synthetic organic compound belonging to the benzodioxepinone family, used exclusively as a fragrance ingredient in cosmetics and personal care products.
