What it is
Sodium Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer is a synthetic crosslinked acrylic polymer supplied as a pre-neutralized powder or liquid dispersion. It thickens water phases and stabilizes oil-in-water emulsions, producing a fresh, fast-absorbing gel feel that is popular in serums and light sunscreens. It works across a broad pH range and can be cold-processed, which makes it convenient in modern formulations.
Safety & warnings
As a high-molecular-weight polymer it is not absorbed into skin and is generally considered non-irritating and non-sensitizing at use levels.
Origin & sourcing
Synthetic; manufactured by polymerizing acrylic monomers and supplying the polymer in neutralized salt form.
