POLYCAPROLACTONE-POLYURETHANE MICROPARTICLES COATED WITH INORGANIC METAL OXIDES AND METHODS FOR THE PREPARATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/075773
Kind Code:
A1
Abstract:
Provided are compositions and methods that are useful for personal care compositions. The compositions comprise polycaprolactone-polyurethane microparticles coated with inorganic metal oxide particles, wherein the weight ratio of inorganic metal oxide to polycaprolactone-polyurethane is in a range of from 5:95 to 2:8, and the polycaprolactone-polyurethane microparticles have an average particle size of 0.1 to 50 microns. Also provided are methods of preparation of such compositions, as well as methods for lightening skin tone comprising topically administering such compositions to the skin, and methods for improving visible light scattering of a composition including a pigment grade inorganic metal oxide particle comprising adding to such composition a voided latex particle.
