Definitions

  • the present invention relates to moldings which, in addition to a cosmetically acceptable carrier, contain at least one cosmetic active ingredient, at least one pearlescent pigment and at least one dissolution accelerator, and a process for treating keratin fibers with these moldings.
  • the pearlescent pigments that can be used for this purpose impart the desired optical effect to a shaped body, but it has been found that shaped bodies with pearlescent pigments have a slowed down dissolution rate. Moldings with pearlescent pigments continue to tend to form small clumps during dissolution, which in turn impair the rheology of the application mixture. Consequently, both the solution behavior of the pearlescent pigment-containing moldings, in particular in viscous media such as creams, and the rheology of the application mixture pose a problem.
  • the object was therefore to provide moldings which satisfy both the dissolving behavior of the molded body and the rheology of the resulting application mixture and at the same time enable the cosmetic active ingredients to have an optimal effect.
  • a first subject of the present invention is therefore molded articles containing, in addition to a cosmetically acceptable carrier, at least one cosmetic active ingredient, and
