Starch Octenylsuccinate
What is Starch Octenylsuccinate?
Starch octenylsuccinate is a chemically modified form of natural starch, typically sourced from corn or potatoes, esterified with octenylsuccinic anhydride to enhance its hydrophobic properties. This alteration allows it to effectively absorb oils and sebum while maintaining stability in formulations. Commonly found in powder-based cosmetics like dry shampoos, face powders, and foundations, it functions as an absorbent to control shine and a viscosity controller to improve texture. In emulsions and creams, it stabilizes mixtures by preventing separation and provides a smooth application. Its structure enables swelling in water or binding to lipids, making it versatile for oil-control products without clogging pores.
