A designation for a mixture of quaternary ammonium compounds used as effective antistatic and conditioning agents in hair and skin care formulations.
Quaternium-30 is a Cosmetics Directive INCI designation for a mixture of quaternary ammonium salts. The exact composition varies by manufacturer but typically includes alkyl trimethyl ammonium chlorides. Quaternary ammonium compounds in this class are widely used and generally considered safe at permitted concentrations (typically ≤5% in rinse-off products). EU CosIng does not list Quaternium-30 as a whole in Annex II or III, but individual components may be subject to review. Overall safety depends on the specific mixture composition.
