  • the change in viscosity as a function of time, in particular the storage time of the composition is particularly problematic. Such a change in the viscosity of the composition over time is undesirable since it is perceived by the consumer as a negative quality characteristic of the composition.
  • the compositions according to the invention made it possible to achieve stabilization of the viscosity values over time in an advantageous manner.
