Oligo(β-amino ester)s, obtainable by aza-Michael addition of primary monoamines or primary or secondary diamines to diesters from monoethylenically unsaturated monocarboxylic acids and diols, is included in a surfactant-containing aqueous detergent solutions in order to prevent the transfer of textile dyes from colored textiles to uncolored textiles or textiles of other colors when washing textiles in the detergent solutions.
Claims8
A method for washing white or colored textiles comprising:
- a step of contacting the textiles with a surfactant-containing aqueous liquor,
- wherein the surfactant-containing aqueous liquor contains an oligo(β-amino ester) obtainable by aza-Michael addition of primary monoamines or primary or secondary diamines to diesters from monoethylenically unsaturated dicarboxylic acids and diols.
A detergent composition comprising;
- a surfactant, and a dye transfer inhibitor in a dye transfer inhibiting amount;
- wherein the dye transfer inhibitor comprises an oligo(β-amino ester), obtainable by aza-Michael addition of primary monoamines or primary or secondary diamines to oligoesters from monoethylenically unsaturated dicarboxylic acids and diols.
