摘要:
Disclosed is the use of amines and amides for the stabilization of a cosmetic composition comprising: (a) an organic micronized UV absorber selected from a benzophenone derivative and (b) a dibenzoylmethane derivative. The use of the amines and amides results in the stabilization of the end-product formulations.
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 the use of an insoluble or sparingly soluble micronized substance class which is not a cosmetic UV absorber and which is dispersed in the oil- or water-phase of a cosmetic or dermatological composition for the enhancement of light protecting action of this cosmetic or dermatological composition comprising at least one cosmetic UV filter which is soluble in the water- or oil-phase. The cosmetic preparation according to the invention shows a remarkable increase in SPF.
