Sodium 2-acrylamido-2-methylpropanesulfonate-sodium acrylate polymer

Sodium 2-acrylamido-2-methylpropanesulfonate-sodium acrylate polymer (CAS 37350-42-8) is an anionic copolymer for rheology control. Also marketed as sodium acrylate/sodium acryloyldimethyl taurate (ATBS) copolymer.

Where is Sodium 2-acrylamido-2-methylpropanesulfonate-sodium acrylate polymer used?

• Water treatment: flocculant and dispersant improving solids separation in municipal and industrial effluent
• Personal care: builds viscosity and stabilizes emulsions in creams, lotions and sunscreens without high shear mixing
• Home care and industrial cleaning: suspends particles and maintains formula stability over a wide pH range
• Textile and paper processing: retention and drainage aid improving fiber binding and reducing raw material loss
• It is an aqueous dispersion or oil-in-water emulsion, with mineral oil and trideceth-6 pre-blended for cosmetic use.

Good to know: Purity and active content specifications vary by grade; cosmetic-grade material typically conforms to standards. Technical and industrial grades serve water treatment and process industries.
