Docosyltrimethylammonium Methyl Sulphate (BTMS) -CAS 81646-13-1
Docosyltrimethylammonium Methyl Sulphate (BTMS) is a high-efficiency mild cationic conditioning surfactant, specially developed for gentle daily chemical care formulas. Different from traditional strong-irritation quaternary ammonium salts, BTMS has ultra-low skin and hair irritation, no cumulative irritation, and excellent antistatic, softening and emulsifying properties. It can effectively smooth hair frizz, improve dry and rough hair texture, and form a protective moisturizing film on hair and skin surface. With stable formula adaptability, it will not cause product yellowing or formula instability. It is a core mild conditioning raw material for high-end salon-grade hair care and sensitive-friendly daily chemical products.
Key Benefits
