Definitions

  • the present invention relates to a cosmetic preparation containing dialkyl adipates and a precursor for 4- (tert-butyl) -4'-methoxydibenzoylmethane.
  • UVA and UVB filters are summarized in most industrialized countries in the form of positive lists such as Appendix 7 of the Cosmetics Regulation.
  • sunscreens 4- (tert-butyl) -4'-methoxydibenzoylmethane is usually used as UV filter.
  • this UV filter has the known disadvantage of not being particularly photostable on its own, but slowly decomposing under UV-B radiation in particular.
  • 4- (tert-butyl) -4'-methoxydibenzoylmethane has the likewise known disadvantage of not being particularly soluble in cosmetic preparations, but rather of crystallizing out of the preparation relatively quickly. This also affects the durability and shelf life of the sunscreen, in particular their storage and temperature stability.
  • a relatively new approach to solving these problems of 4- (tert-butyl) -4'-methoxydibenzoylmethane in cosmetic preparations is to use precursors of 4- (tert-butyl) -4'-methoxydibenzoylmethane to be used in the preparations. These are then used, since they transform under sunlight into the 4- (tert-butyl) -4'-methoxydibenzoylmethane, as the starting material for a resulting in the application of UV-A protection.
  • the object is achieved by containing a cosmetic preparation
