Abstract
The invention relates to a process for preparing polysaccharide-based microparticles with improved mechanical properties and hydrolytic stability. The spherical particles are useful as exfoliating agents in cosmetic formulations, in replacement of the newly banned plastic microbeads. The method comprises the preparation of hydrogel particles, drying of the particles, and a solid-state reaction that results in the covalent stabilization of the material. The invention also encompasses microparticles made using the method.
