Definitions

  • the present invention relates to a cosmetic preparation containing ethanol and a precursor for 4- (tert-butyl) -4'-methoxydibenzoylmethane.
  • UV-A filter 4- (tert-butyl) -4'-methoxydibenzoylmethane is usually used as the UV-A filter.
  • this UV filter has the known disadvantage, not alone To be photostable, but slowly decompose especially under UV-B radiation.
  • 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
  • the preparations according to the invention are distinguished by a significantly faster and more complete conversion of the precursor under UV light into 4- (tert-butyl) -4'-methoxydibenzoylmethane than is the case in the preparations of the prior art.
  • the preparations according to the invention have the surprising advantage that they have a significantly lower yellowing before application (ie before the skin creamed with the preparation is exposed to sunlight) than is the case with preparations which contain an equivalent amount of (tert-butyl) -4'-methoxydibenzoylmethane included.
