Definitions

  • the present invention relates to the use of carboxylated triazine derivatives as dye transfer inhibiting agents in the washing of textiles and detergents containing such compounds.
  • Detergents contain in addition to the indispensable for the washing process ingredients such as surfactants and builders usually other ingredients that can be summarized under the term washing aids and the so different drug groups such as foam regulators, graying inhibitors, bleach, bleach activators and enzymes include.
  • 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.
  • detergents In order to avoid these undesirable side effects of removing dirt from textiles by treatment with usually surfactant-containing aqueous systems, detergents, especially when they are provided as so-called color or colored laundry detergents for colored textiles, contain active ingredients which prevent the detachment of dyes from the textile or At least the deposition of detached, located in the wash liquor to avoid dyes on textiles.
  • Many of the commonly used polymers have such a high affinity for dyes that they draw them more from the dyed fiber, resulting in increased color losses.
  • Another object of the invention is a color-protective detergent, comprising a color transfer inhibitor in the form of a Triaziriderivates the above-defined general formula II in addition to conventional ingredients compatible with this ingredient.
