Also known as
Simulgel NS Simulgel EG HEA/Sodium AMPS Copolymer Sodium Acryloyldimethyl Taurate/Hydroxyethyl Acrylate Copolymer
Compatibility
Works well with:
Glycerin Niacinamide Hyaluronic Acid Panthenol Phenoxyethanol Silicones
Use caution with:
high concentrations of cationic surfactants high electrolyte concentrations
This polymer is anionic and can lose viscosity or precipitate in the presence of high concentrations of cationic actives or very high salt loads; moderate electrolytes are generally tolerated. It is compatible with a wide range of nonionic and anionic ingredients and pairs well with silicones to create elegant skin feel. Adjust pH to the 4.5–7.0 range for optimal viscosity development.
Formulation notes
Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer is a synthetic, water-swellable polymer used primarily to thicken and stabilize aqueous and oil-in-water emulsion systems without the need for high shear or neutralization steps. It imparts a light, non-sticky gel texture and contributes to the suspension of insoluble particles and the stabilization of emulsions at low use levels. It is considered safe at cosmetic use concentrations, though the residual monomer content should be within regulatory limits as specified by supplier.
