Skin Benefits
Improves longevity and smudge resistance of cosmetics while improving glide, and leaves a silky, lightweight finish that can lessen tackiness.

Comedogenic Rating
This ingredient is not typically evaluated for comedogenicity, and no standardized rating is available.

Is C12-18 Alkanoyl Glycerin/Sebacic Acid Copolymer a Good Ingredient?
It reliably boosts wear and slip through a flexible film and is generally low-irritating and stable in formulas, which earns a Good rating; it lacks strong evidence for direct skin improvements beyond texture optimization, which keeps it short of Great.
