Polyacrylate Anti-Redeposition Polymer
CAS Number: 9003-04-7
Polyacrylate anti-redeposition polymer is a low-molecular-weight polyacrylic acid salt used in detergent formulations to prevent soil and calcium carbonate from redepositing on washed fabrics and surfaces. It also acts as a scale inhibitor and crystal growth modifier, keeping minerals in suspension for easier rinsing. It is an essential co-builder in modern phosphate-free detergent systems.
