Definitions

  • the present invention relates to cosmetic and / or dermatological preparations containing a) a lipophilic phase in a concentration of 20 to 70% by weight, b) an aqueous phase in a concentration of 20 to 40% by weight, c) Pickering pigments made of titanium dioxide with a particle diameter of 10 to 100 nm and / or iron oxides with a particle diameter of 100 to 800 nm in one
  • Lipstick is one of the most used decorative cosmetics. More than 50% of women in Germany use it. In addition to emphasizing the color of the lips, it is usually also used for lip care. In addition to the classic lipstick, lip gloss and contour pencils are also used. Lip-Gloss gives the lips a strong decorative shine, contour pencils are used to emphasize the lip edges.
  • the skin of the lips consists of a thin layer of horn. The leather skin underneath pushes well-perfused papillae right up to the lip surface. Hence the natural look of the lips.
  • Lipsticks usually consist of a wax matrix in which liquid and semi-solid oils as well as pigments and fillers are incorporated. So far, these water-free systems have not allowed water-soluble components to be incorporated into the preparations. In order to remedy this disadvantage of the prior art, there have been a number of attempts to formulate pen-shaped W / O emulsions. As a rule, larger amounts of emulsifier must be used in these cases in order to obtain both a stable emulsion and pigment dispersion (e.g. EP 1 018 332, EP 1 064 908).
  • the object is achieved by cosmetic and / or dermatological preparations containing a) a lipophilic phase in a concentration of 20 to 70% by weight, b) an aqueous phase in a concentration of 20 to 40% by weight, c) Pickering pigments from titanium dioxide with a particle diameter of 10 to 100 nm and / or iron oxides with a particle diameter of 100 to 800 nm in an amount of 1 to 6% by weight, d) coated titanium dioxide pigments with a particle diameter of 100 to 2000 nm in an amount from 0.1 to 10% by weight, e) further color pigments with an amount of 0.1 to 20% by weight, in each case based on the total weight of the formulation, in addition to any other cosmetic and / or dermatological active ingredients, auxiliaries and additives.
  • the solid substance (the Pickering pigment) accumulates at the oil / water phase boundary in the form of a layer, which prevents the disperse phases from flowing together.
  • the surface properties of the solid particles which should show both hydrophilic and lipophilic properties.
  • EP 0686 391 also describes emulsions with surface-active pigments as surface-active agents, this document could not point the way to the present invention, since polyalkylsilsesquioxane particles are used as Pickering pigments in it.

  • the documents DE 197 12 483, DE 198 26 118, 198 42 730 and 198 42 732 describe pickering emulsions with microfine surface-active particles which are quite emulsifier-free in general. In some cases, however, metal oxides with a particle size of less than 200 nm are expressly disclosed.
  • DE 43 03 983 describes light protection formulations but no decorative lipsticks.
  • the formulations disclosed in this document contain no color pigments and have no consistency typical of lipsticks, so that this disclosure could not point the way to the present invention.
  • DE 198 42 730 and DE 198 42 732 basically disclose Pickering emulsions, which can also be used as make-up and / or lip care products, but these writings do not take into account the specifics of lipsticks.
