Chitosan Succinamide

What is Chitosan Succinamide?

Chitosan Succinamide is a derivative of chitosan, a polysaccharide obtained from chitin in crustacean exoskeletons such as shrimp shells. Through succinamide modification, it gains improved water solubility while retaining beneficial properties. Commonly found in hair styling products, sunscreens, and makeup, it serves as a film former. In formulations, it deposits a thin, continuous layer on skin or hair, enhancing adhesion and creating barriers against moisture and friction. This cationic polymer interacts with negatively charged hair proteins or skin surfaces, promoting even coverage and durability without heaviness. Its role supports product functionality across cosmetics categories focused on protection and longevity.
