Sodium Polyacrylate Starch



Sodium Polyacrylate Starch description

Sodium polyacrylate start is a mixture of a natural starch combined with a synthetic acrylate polymer. As with most starches, it works in cosmetics as a texture enhancer, thickening agent, stabilizer, and absorbent, the latter benefit occurring when higher amounts are used. Sodium polyacrylate starch is considered safe as used in cosmetics; its size does not allow penetration past skin’s surface. In its raw form, it is a white powder.
