Sodium Acryloyldimethyltaurate Copolymer
What is Sodium Acryloyldimethyltaurate Copolymer?
Sodium Acryloyldimethyltaurate Copolymer is a high-molecular-weight, synthetic polymer created through polymerization of acryloyldimethyltaurate sodium salt with acrylic monomers. Originating from petrochemical sources, it serves primarily as a rheology modifier in aqueous cosmetic systems like gels, lotions, and serums. In formulations, it rapidly absorbs water, swells, and forms a three-dimensional gel network that increases viscosity, suspends particles, and stabilizes emulsions against separation. This enables lightweight, spreadable textures that feel non-greasy on skin. Its large size limits absorption through the skin barrier, supporting use in diverse products from cleansers to sunscreens while maintaining formula integrity over time.
Benefits
Creates smooth, lightweight textures for easy application
