    摘要: Disclosed is the use of an aqueous dispersion comprising (a) a micronized sparingly soluble organic benzophenone derivative of formula (1), selected from the crystal modifications (B) and (C), wherein the crystal modification (B) is characterized by a peak in the X-ray diffraction pattern at a d-spacing of about 7.70; and wherein the crystal modification (C) is characterized by a peak in the X-ray diffraction pattern at a d-spacing of about 7.06; and (b) a dispersing agent selected from anionic, non-ionic and amphoteric surfactants; for protecting the human skin from browning and skin aging. The new crystal modification (C) represents a thermodynamically stable compound of formula (1) at 25° C. This modification is therefore suitable in dispersions comprising micro-fine particles.

    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 (c1) 20% to 99% of at least one insoluble micronized organic UV-screening active with a mean particle size ranging from 0.01 μm to 2 μm; and (c2) 0.5% to 80% of at least one primary C6-C28 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.
