Cocodimonium Hydroxypropyl Hydrolyzed Keratin

What is Cocodimonium Hydroxypropyl Hydrolyzed Keratin?

Cocodimonium Hydroxypropyl Hydrolyzed Keratin is a chemically modified protein derived from hydrolyzed keratin, typically sourced from animal wool or feathers. The keratin undergoes hydrolysis to break it into smaller peptides, then hydroxypropyl groups are added for solubility, and cocodimonium moieties—quaternary ammonium compounds linked to coconut-derived fatty chains—impart a positive charge. This cationic structure enables strong adhesion to the negatively charged surface of hair and skin. Primarily featured in hair care formulations like conditioners, shampoos, and styling aids, it forms a protective, lubricating film on hair shafts to minimize friction and environmental damage. In skin products, it supports a smooth texture. Its amphoteric nature balances conditioning without excessive buildup in rinse-off applications, enhancing overall product performance through improved substantivity and mildness.
