Title:
POLYMER COMPOSITE PARTICLES CONTAINING LARGE AMOUNT OF ORGANIC UV BLOCKING AGENT AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2017/171138
Kind Code:
A1
Abstract:
The present invention relates to polymer composite particles containing a large amount of an organic UV blocking agent and a method for preparing same, and more particularly, to spherical polymer composite particles in which a solid phase organic UV blocking agent is inserted between polymer matrices at 40 to 50 wt%. The polymer composite particles of the present invention include a significantly large amount of the organic UV blocking agent when compared to polymer composite particles, has excellent light stability, despite including the large amount of the organic UV blocking agent, has superior UV blocking ability with respect to a UV-B region as well as a UV-A region, provides highly favorable skin stability and texture when applied to cosmetics, and can improve the UV blocking ability significantly.
