Laundry detergents and laundry treatment compositions comprising dye-transfer-inhibiting dye fixatives
The following dye-transfer-inhibiting dye fixatives are used in laundry detergents which comprise nonionic surfactants: Reaction products of a) amines with epichlorohydrin or b) cyanamide with amines and aldehydes.
1. A laundry detergent for inhibiting dye-transfer in washing dyed textiles, said detergent consisting of a cellulase enzyme, a nonionic surfactant, a dye-transfer-inhibiting dye fixative, where this dye-transfer-inhibiting dye fixative is obtained by reacting dicyanodiamide with ethylenediamine and formaldehyde, and at least one component selected form the group consisting of detergent builder anionic surfactants, cationic surfactants, amphoteric surfactants, zwitterionic surfactants, soil release polymer, dye transfer inhibitor, bleach, fabric softening component, perfume, emulsifier, electrolyte, filler, optical brightener, disinfectant, alkali, hydrotropic compound, antioxidant, solvent, solubilizer, dye, and mixtures thereof.
2. The laundry detergent as claimed in claim 1 , wherein the at least one component is an anionic surfactant and said laundry detergent consists of no detergent builder.
3. The laundry detergent as claimed in claim 1 , wherein the at least one component is detergent builder and said laundry detergent consists of no anionic surfactants.
4. The laundry detergent as claimed in claim 1 , wherein the at least one component is a cationic surfactant.
5. The laundry detergent as claimed in claim 1 , wherein the at least one component is a dye transfer inhibitor.
6. The laundry detergent as claimed in claim 1 , wherein the at least one component is a soil release polymer.
7. The laundry detergent as claimed in claim 1 , wherein the at least one component is bleach.
