Sodium Acrylate/Sodium Acrylamidomethylpropane Sulfonate Copolymer
What is Sodium Acrylate/Sodium Acrylamidomethylpropane Sulfonate Copolymer?
Sodium Acrylate/Sodium Acrylamidomethylpropane Sulfonate Copolymer is a synthetic polymer created by copolymerizing sodium acrylate and sodium 2-acrylamido-2-methylpropane sulfonate. Widely used in cosmetics like lotions, creams, gels, and hair products, it acts as a viscosity controlling agent. In formulations, it builds a flexible gel network in water-based systems, raising thickness while maintaining clarity and light feel. This structure tolerates salts and other actives well, preventing thinning or separation. It aids even spreading, holds particles in place, and refines sensory qualities, suiting diverse product types from thin serums to rich emulsions for everyday use.
