Definitions

  • the present invention relates to detergents which, in addition to conventional constituents, contain a dye-transfer-inhibiting active ingredient in the form of a hyperbranched polyesteramide.

  • auxiliaries also include substances which are intended to prevent dyed textiles from causing a changed color impression after washing. This color impression change washed, i. cleaner, textiles can be based on the one hand on the fact that dye components are removed by the washing process from the textile ("fading"), on the other hand may be deposited by differently colored textiles dyes on the textile ("discoloration").
  • the discoloration aspect may also play a role in undyed laundry items when washed together with colored laundry items.
