Corn Starch/Maltodextrin Crosspolymer

What is Corn Starch/Maltodextrin Crosspolymer?

Corn Starch/Maltodextrin Crosspolymer is a synthetic polymer created by crosslinking corn starch, a natural polysaccharide extracted from corn kernels, with maltodextrin, a starch derivative produced through hydrolysis. This process yields a highly porous, sponge-like structure capable of absorbing large amounts of liquids. In cosmetics, it belongs to the absorbent and texture-modifying category, appearing in powders, masks, creams, and dry shampoos. It functions by swelling upon contact with sebum or water, trapping oils and moisture to deliver a dry, matte finish. Additionally, it improves product spreadability, provides a silky powdery feel, and acts as a bulking agent to stabilize formulations without adding greasiness.
