Definitions

  • the present invention is a barium sulfate-containing preparation, a process for their preparation and the use of this preparation.
  • the present invention is a barium sulfate-containing topically applicable preparation, preferably a cosmetic or dermatological formulation, a process for their preparation and the use of this preparation, preferably as an anti-wrinkle cream.
  • barium sulfate is available inexpensively, on the other hand it can easily be incorporated into care products.
  • the barium sulfate used in the above preparations has a particle size below 100 nm, preferably below 50 nm (WO-A-0192157), or an average particle size below 100 nm, preferably between 5 and 50 nm, in particular between 15 and 30 nm (EP-A-14371 17, EP-A-136941 1, DE-A-10063433).
  • barium sulfate with an average particle size of 100 nm has only a low relative scattering power for visible light, for example 0.01 in the case of light having a wavelength of 550 nm. For smaller particle sizes, the scattering power with light of this wavelength is even lower.
  • the use of barium sulfate of these particle sizes therefore requires further, mostly expensive active ingredients and add additives to the formulations to reduce, smoothen, or visually conceal wrinkles.
  • the object of the present invention is to overcome the disadvantages of the prior art.
  • it is an object of the present invention to provide a cosmetic preparation which contains barium sulfate and which is suitable for reducing, smoothing or visually concealing wrinkles.
  • a further object of the invention is to provide a cosmetic preparation which contains barium sulfate and is also suitable without expensive active ingredients and additives for reducing, smoothing or visually concealing wrinkles.
  • Another object of the invention is to provide a cosmetic preparation containing barium sulfate which is suitable over the entire spectrum of visible light for reducing, smoothening or visually concealing wrinkles.
  • barium sulfate both synthetic and natural
  • barium sulfate is capable of scattering, reflecting and refracting light. Wrinkles appear darker than the surrounding skin surface due to limited diffuse light scattering. In particular, by the scattering power of barium sulfate these wrinkles are perceived optically less.
  • the relative scattering power of barium sulfate particles is strongly dependent on the mean grain size.
  • the relative scattering power with visible light of a wavelength of 550 nm at 0.1 microns is only 0.01, at 0.2 microns already 0.04, then reaches at a mean grain size of about 1 micron, the maximum of 0.14, to drop to 0.06 at 10 nm and to approximately 0.035 at 20 nm.
  • Corresponding dependencies are found for other areas of visible light, with shorter wavy light scattering more on smaller and longer wavy light on larger particles.
  • the object is achieved by the use of barium sulfate having a particle size of 1 to 30 ⁇ m.
  • the barium sulfate particles can be both aftertreated and untreated. Furthermore, it has surprisingly been found that the problem is solved by the use of barium sulfate of a particle size of 0.1 to 8 microns.
