Acrylic acid homopolymer-sodium salt
Acrylic acid homopolymer-sodium salt, or sodium polyacrylate, is a common ingredient in detergent formulations, where it functions as a dispersant and chelating agent. It prevents the redeposition of dirt and the buildup of inorganic precipitates, such as limescale, by binding to metal ions like calcium and dispersing solid particles, thus improving washing efficiency, especially in phosphate-free detergents.
