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.
