Definitions

  • Liquid detergents are known in the art and have become increasingly popular with consumers in recent years as they offer a number of advantages over solid detergents.

Especially for the washing of colored textiles, they have gained more and more popularity since their market launch.

  • Suitable polymers include polyvinylpyrrolidone (PVP), polyvinylimidazole (PVI), copolymers of vinylpyrrolidone and vinylimidazole (PVP / PVI), polyvinylpyridine-N-oxide, poly-N-carboxymethyl-4-vinylpyridium chloride and mixtures thereof.
  • Particular preference is given to using polyvinylpyrrolidone (PVP), polyvinylimidazole (PVI) or copolymers of vinylpyrrolidone and vinylimidazole (PVP / PVI) as color transfer inhibitor.
  • hydrotropes may be used in addition to the surfactant systems described herein.
  • the term "hydrotrope" as used in the context of the present invention refers to additives or solvents which cause the water solubility of poorly soluble (hydrophobic) organic compounds to increase, whereby a second component (ie the hydrotrope) is added to the sparingly soluble substance
  • hydrotropes have hydrophilic and hydrophobic structural units (such as surfactants) but without the tendency to form aggregates in water (as opposed to surfactants) .
