USE OF AMPHIPHILIC COPOLYMERS TO STABILIZE DISPERSION OF INSOLUBLE ORGANIC COMPOUNDS FOR SCREENING OUT UV RADIATION, DISPERSIONS STABILIZED WITH THESE COPOLYMERS AND COSMETIC COMPOSITIONS CONTAINING THEM

摘要

PROBLEM TO BE SOLVED: To provide dispersions stabilized with an amphiphilic copolymer and of insoluble organic compounds comprising at least one group absorbing UV radiation, which is in the form of particles with a mean size of between 10 nm and 5 μm, to provide cosmetics containing them, and to provide a process for preparing the dispersions.;SOLUTION: To stabilize the dispersion of an insoluble organic composition comprising at least one group that absorbs UV radiation, which is in the form of particles with a mean size of between 10 nm and 5 μm, at least one amphiphilic copolymer comprising at least one hydrophilic block and at least one hydrophobic block is used. And also dispersions stabilized with the amphiphilic copolymers and cosmetic compositions containing them and for topical application, in particular antisum compositions, are provided.;COPYRIGHT: (C)2007,JPO&INPIT
