About
A sodium salt of a naturally occurring mucopolysaccharide (heparosan) that acts as a humectant and skin-protecting ingredient similar to hyaluronic acid in function.
Sodium Heparosan is the sodium salt of heparosan, a naturally occurring mucopolysaccharide composed of repeating β-D-glucuronic acid and N-acetyl-α-D-glucosamine units — the same disaccharide backbone found in heparan sulfate, a component of the extracellular matrix. It is produced biotechnologically and is not derived from animal sources. Heparosan is not listed in EU Annex II or III under Regulation 1223/2009 and has no established restrictions. As a high-molecular-weight polymer, it does not penetrate the skin barrier but forms a protective hydrating film on the surface.
Function
Skin benefits
- Excellent humectant properties: can bind and retain water at the skin surface
- Film-forming skin-protecting action helps reinforce the skin barrier
Known concerns
- High molecular weight limits skin penetration; primarily surface-acting
- Batch-to-batch variability in molecular weight from fermentation processes (quality control consideration)
