Highly-substituted Succinylated Chitosan: A New Natural Polysaccharide Cosmetic Raw Material for Moisturizing & Skin Barrier Repair

Recently, highlysubstituted succinylated chitosan, a new natural polysaccharide cosmetic raw material, has attracted wide attention in skincare formulation field. Modified from marinesourced chitosan via succinylation, this material achieves greatly improved watersolubility with high degree of substitution, and features excellent biocompatibility, filmforming property as well as moisturizing and repairing performance.

Rich in hydrophilic carboxyl and hydroxyl groups, highlysubstituted succinylated chitosan binds water molecules firmly. It forms a thin, breathable protective film on skin surface to reduce transepidermal water loss, delivers longlasting moisturization, relieves external irritation and helps repair skin barrier. It also shows conditioning and thickening effects, compatible with toners, serums, moisturizing creams, facial masks and other skincare formulations.

As a biodegradable green raw material, highlysubstituted succinylated chitosan provides an alternative to hyaluronic acid for cosmetics industry, boosts innovation of naturalderived functional ingredients and enjoys broad market prospects.
