MICRO-PARTICULATE ORGANIC UV ABSORBER COMPOSITION |
摘要 |
Disclosed is a topically applicable water-in-oil (w/o) or water-in-silicone (w/Si) formulation comprising: (a) at least one aqueous phase; (b) at least one fatty phase; (c) an effective UV-photoprotecting composition comprising (c<SUB>1</SUB>) 20% to 99% of at least one insoluble micronized organic UV-screening active with a mean particle size ranging from 0,01µm to 2 µm.; and (c<SUB>2</SUB>) 0.5% to 80% of at least one primary C<SUB>6</SUB>-C<SUB>28</SUB> fatty alcohol. The combination of a micronized organic UV absorber and a specific fatty alcohol allows a maximum of miscibility of micronized organic particles within the continuous oil phase of w/o emulsion wherein the micronized particles are stabilized in the oil phase of the composition. Simultaneously the crystal growth of micronized organic UV absorbers within W/O emulsions is limited or even eliminated. |
