Hydrolyzed Corn Starch Octenylsuccinate

What is Hydrolyzed Corn Starch Octenylsuccinate?

Hydrolyzed Corn Starch Octenylsuccinate is a chemically modified derivative of corn starch, where the starch undergoes hydrolysis to reduce molecular size and octenylsuccinate modification to enhance hydrophobicity and stability. Derived from natural corn, this polysaccharide acts primarily in powder-based and emulsion cosmetics like foundations, dry shampoos, and sunscreens. It functions by swelling in water to thicken formulations, adhering to skin to control shine through sebum absorption, and creating a sheer, flexible barrier that improves product longevity and sensory feel. Its amphiphilic nature allows it to stabilize emulsions and pressed powders, preventing separation while delivering a soft-focus effect without heaviness.
