About

Beta-glucan/chitosan is a hybrid biopolymer combining two natural polysaccharides with synergistic skin-barrier and wound-healing properties, widely used in cosmetic formulations for moisturization.

Beta-Glucan/Chitosan is a combination of two naturally derived polysaccharides — beta-glucan from Antrodia camphorata fruiting body and chitosan from crustacean shells. Both are listed in the EU CosIng database. Beta-glucan is listed without restriction; chitosan is also listed but requires purity standards (deacetylation degree >75%). No EU maximum concentration limit is specified. The ingredient is not listed in any restricted annex, but crustacean-derived chitosan requires allergy labeling.

Skin benefits

  • Beta-glucan provides excellent moisturization and skin-barrier support
  • Chitosan has antimicrobial and film-forming properties
  • Synergistic wound-healing effects documented

Known concerns

  • Chitosan is derived from crustaceans — must be labeled for shellfish allergy
  • May form a film on skin causing a tight sensation
  • Very rare reports of mild irritation
