A kind of surface modified sodium hyaluronate pearl pigment and its preparation method and application

Abstract

The application discloses a kind of surface layer modified sodium hyaluronate pearlescent pigments and its preparation method and application, by containing epoxy group silane as bridging material, biologic macromolecule sodium hyaluronate is chemically modified on the surface of pearlescent pigment to form polymer brush, and then improve the water permeability and air permeability of the interface of pearlescent pigment and skin, reduce the interference to skin microenvironment;Meanwhile, there is hydrogen bond and ionic interaction between sodium hyaluronate polymer brush and skin, can be quickly eluted under high water content, so it also has good elution property.In addition, the process of the application also does not need to introduce carboxyl activator, no byproduct is generated, and the post-treatment process is simple, safe and environmentally friendly.
