Ammonium Acryloyldimethyltaurate/Steareth-25 Methacrylate Crosspolymer
What is Ammonium Acryloyldimethyltaurate/Steareth-25 Methacrylate Crosspolymer?
Ammonium Acryloyldimethyltaurate/Steareth-25 Methacrylate Crosspolymer is a synthetic, high-molecular-weight polymer created through crosslinking of hydrophilic ammonium acryloyldimethyltaurate monomers with hydrophobic steareth-25 methacrylate units. This dual nature allows it to form soft, clear gels when hydrated. Primarily used in leave-on skincare products like creams, lotions, and serums within the emulsion and gel categories, it functions by absorbing water to swell and create a three-dimensional network that controls viscosity. It strengthens the interface between oil and water phases, preventing separation and enhancing product spreadability while maintaining stability over time without altering pH significantly.
