Definitions

  • the present invention relates to a cosmetic preparation comprising an acrylate copolymer having a glass transition temperature of -5 to -15 ° C, measured by means of DSC and water-soluble UV filters.
  • UV radiation causes a pigmentation in the sense of melanin formation.
  • the ultraviolet radiation of sunlight also has a damaging effect on the skin.
  • long-term damage such as an increased risk of developing skin cancer occurs due to excessive exposure to light from the UVB range (wavelength: 280-320 nm).
  • the excessive action of the UVB and UVA radiation also leads to a weakening of the elastic and collagen fibers of the connective tissue. This leads to numerous phototoxic and photoallergic reactions and leads to premature skin aging.
  • UVA and UVB filters are in the form of positive lists in most industrialized countries such as Appendix 7 of the
  • a relatively new product form for skin care are the hydrodispersions used under the shower, which are applied to the wet skin after a first showering process, with excess being left over in a second showering session, not on the skin Skin fixed preparation is rinsed off (so-called in-shower products, which are analogous to shower gel used, in contrast to these, however, do not cleanse, but apply the care product to the skin).
  • a disadvantage of the conventional in-shower products is the fact that they can hardly be effectively applied with UV light protection filters for the UV protection of the skin. Most of the UV filters are rinsed more or less completely from the skin during the second showering process, so that virtually no UV protection can occur.
