Sodium polystyrene sulfonates (inci)

"Sodium" means the element sodium; polymer or copolymer based on styrene (vinylbenzene) and possibly other monomers. Sulfonates are salts or esters of sulfonic acids (alkanesulfonic acids, alkylsulfuric acids).

Sodium polystyrene sulfonates are substances which are used in cosmetic preparations where they act as emulsion stabilizer (supports emulsion formation and improves product stability), surfactant (washing-active substance), viscosity regulator (increases or decreases the viscosity of cosmetic products) and film former (forms a film on skin, hair or nails).
