Ammonium Polyacryldimethyltauramide

What is Ammonium Polyacryldimethyltauramide?

Ammonium Polyacryldimethyltauramide is a synthetic, high-molecular-weight copolymer produced from acrylic acid derivatives and tauramide units, neutralized with ammonium hydroxide. It falls under rheology modifiers in cosmetic formulations. This ingredient works by creating a flexible, three-dimensional hydrogel network in water-based systems, boosting viscosity and providing shear-thinning properties for easy spreading. It excels in challenging environments with high electrolyte levels, such as those containing salts or surfactants, maintaining clarity and preventing syneresis or phase separation. Commonly found in serums, gels, and lightweight creams, it delivers a silky, non-tacky skin feel while supporting suspension of particles and actives for uniform distribution. Its mild film-forming action enhances product performance without heaviness.
