Common Name(s): Sodium heparosan,sodium heparosan,heparin precursor polysaccharide,non-anticoagulant gag humectant

CAS Number: N/a

DESCRIPTION

What It Does: Provides ha-equivalent 1,000× water retention and dermal matrix conditioning from the glcua-glcnac gag backbone, delivers anti-inflammatory activity from gag-growth factor binding modulation, and offers the safety advantages of non-anticoagulant heparin precursor versus sulfated heparin.

Why It's Used: Heparosan provides the cosmetic benefits of heparin (wound healing, anti-inflammatory, moisture retention) without anticoagulant risk — the sulfation-free backbone retaining the gag's skin conditioning while eliminating the bleeding risk of medical heparin.

How It Works: Heparosan (glcua-α1,4-glcnac-β1,4 disaccharide repeat) is structurally analogous to hyaluronic acid with n-acetylglucosamine instead of n-acetylgalactosamine. the polyanionic carboxylate backbone provides 1,000× water retention (donnan osmotic pressure). produced by e. coli k5 fermentation providing consistent high-mw polymer (50-500 kda).
