Sodium Polyacryloyldimethyl Taurate

What is Sodium Polyacryloyldimethyl Taurate?

Sodium Polyacryloyldimethyl Taurate is a cross-linked, anionic synthetic copolymer primarily composed of acryloyldimethyltaurate sodium salt monomers. Developed for personal care formulations, it belongs to the class of polyacrylate thickeners used in oil-in-water emulsions, gels, and serums. Upon hydration, it quickly forms a three-dimensional gel matrix that increases viscosity without adding tackiness, enabling precise control over product consistency from thin fluids to rich creams. It reinforces emulsion structures by adsorbing at oil-water interfaces, hindering droplet merging and maintaining homogeneity during storage and application. This results in formulations that dispense evenly, spread effortlessly, and deliver active ingredients uniformly across the skin.
