Acrylamide/Sodium Acryloyldimethyltaurate Copolymer

What is Acrylamide/Sodium Acryloyldimethyltaurate Copolymer?

Acrylamide/Sodium Acryloyldimethyltaurate Copolymer is a lab-synthesized polymer formed by linking acrylamide and sodium acryloyldimethyltaurate monomers. This creates a hydrophilic structure capable of absorbing water to form clear, high-viscosity gels. In cosmetics, it belongs to rheology modifiers, commonly found in creams, lotions, serums, and sunscreens. It functions by self-assembling into a three-dimensional network that traps water and oils, providing shear-thinning properties—thinning under pressure for easy spreading then recovering thickness. This enhances emulsion stability by preventing ingredient separation and improves sensory feel, making products luxurious without greasiness. Its versatility suits both aqueous and emulsified systems, contributing to long-term formula integrity across pH ranges.
