1. Moisture masks containing different molecular weights and/or concentrations of
water-soluble chitosans are pseudoplastic fluids.
2. The apparent viscosity of moisture masks increased with the increasing molecular
weight and/or concentration of water-soluble chitosans used in the formula.This will
improve the stability of the moisture mask,enhance skin hydration,shorten film formation time, and improve skin compatibility. Thus moisture masks containing
water-soluble chitosans will be useful in a wide range of applications.
3. These beneficial effects may be attributed to the good water-holding capacity ,thickening,
and film-formation properties of water-soluble chitosans
