BEHENOYL PG-TRIMONIUM CHLORIDE.

Valuable CAS 69537-38-8 / ANTISTATIC, HAIR CONDITIONING

A high-performance cationic conditioning agent that bridges the gap between hair care and advanced skin barrier support. It is particularly valued for its ability to create sophisticated lamellar structures that lock moisture into the skin surface while providing a silky, non-greasy finish.

Conditioning agent Emulsion stabilizer Antistatic Surfactant

Science

This quaternary ammonium compound carries a positive charge that naturally gravitates toward the negatively charged surfaces of damaged skin and hair. Upon contact, it forms a substantive, uniform film that smooths texture and reduces static, while simultaneously organizing into liquid crystal structures that stabilize emulsions and prevent transepidermal water loss.
