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 hydroxyethyl cellulose.
  • Emulsions are generally understood to mean heterogeneous systems which consist of two liquids which are immiscible or only to a limited extent miscible with one another, which are usually referred to as phases, and in which one of the two liquids is in the form of very fine droplets in the other
  • Liquid is dispersed. Viewed externally and with the naked eye, emulsions appear homogeneous.
  • An essential task of skin care products is to moisten the skin over a longer period of time or to keep it moist.
  • Skin moisturizer is glycerin.
  • glycerin has the disadvantage of being effective skin moisturizing only in higher amounts, but to act very sticky at higher use concentrations. It was therefore the object of the present invention to develop an alternative skin care agent that is less sticky.
  • a relatively new product form for skincare is the hydrodispersions used in the shower, which are applied to the wet skin after a first showering process, wherein subsequently in a second showering process excess, not fixed on the skin preparation is rinsed off (so-called in-shower products, the analog as shower gels are applied, in contrast to these, however, do not clean, but apply the care product on the skin).
  • in-shower products the analog as shower gels are applied, in contrast to these, however, do not clean, but apply the care product on the skin.
  • a disadvantage of the conventional in-shower products is not least 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.
