Expert Verdict

Generally regarded as safe in typical formulation concentrations. As an anionic polymer, low irritation potential. Residual monomer content (especially AMPS monomer) should be controlled. Clear to slightly opaque, colorless, odorless viscous liquid. In skin care, it reduces tack and wetness, improves spreadability, and increases slipperiness. In cleansing products, it enhances lather thickness. Dual anionic charge (carboxylate + sulfonate) provides excellent humidity resistance in hair styling
