AMP-ISOSTEAROYL GELATIN/KERATIN AMINO ACIDS/LYSINE HYDROXYPROPYLTRIMONIUM CHLORIDE.

Valuable CAS 156715-41-2 / ANTISTATIC, HAIR CONDITIONING, SKIN CONDITIONING, SURFACTANT - CLEANSING

A sophisticated quaternized protein complex that combines keratin amino acids with lysine derivatives to create a multifunctional conditioning agent. This cationic compound demonstrates remarkable efficacy in strengthening damaged hair fibers while providing gentle conditioning benefits to skin through its amino acid-rich composition.

antistatic hair conditioning skin conditioning surfactant cleansing

Science

Functions as a targeted repair complex by utilizing its positive charge to electrostatically attract and bind to negatively charged damaged areas on skin and hair cuticles. Forms a breathable protective film that enhances moisture retention, smooths surface texture, and delivers antistatic benefits through its tri-protein amino acid matrix.
