Aluminum starch octenylsuccinate is a modified starch derived from corn or other botanical sources and combined with aluminum salts. It is commonly used in skincare and cosmetic formulations for its ability to absorb excess oil, reduce shine, and improve the texture of products. This versatile ingredient helps create lightweight, non-greasy formulations while providing a silky, smooth finish.
Breaking Down the Term
Aluminum: Refers to the aluminum salts used to modify the starch for enhanced stability and performance.
Starch: A carbohydrate derived from natural sources, typically corn, that acts as an absorbent and texturizer.
Octenylsuccinate: A chemical group that improves the ingredient’s ability to disperse in formulations and resist breakdown over time.
