Hydroxyethyl chitosan is a substance used in cosmetic formulations. Chitosan (from the Greek chiton = undergarment, cover, armour) also called poly-D-glucosamine or polyglucosamine, is a naturally occurring polyaminosaccharide (can also be produced industrially) which is derived from chitin. Hydroxethyl chitosan acts as a film former (forms a film on skin, hair or nails when applied) and viscosity regulator (increases or decreases the viscosity of cosmetic products).
