Abstract
The present disclosure provides improved dye transfer inhibition in the washing of textiles by the use of urea derivatives comprising sulfonic or carboxylic acid groups.
Claims15
Detergent comprising:
- a dye transfer inhibitor in the form of a urea derivative of the general formula I,
- R—B—C(O)—NH—Ar(A)l-NH[—C(O)—NH-L(A)m-NH—C(O)—NH—Ar(A)n-NH]o—C(O)—B—R (I)
- in which
- R denotes a linear or branched alkyl group with 1 to 20 carbon atoms, or a cycloalkyl group with 3 to 20 carbon atoms,
- B denotes 0 or NH,
- Ar denotes an aromatic group, a stilbene group, or a linear, branched, or cyclic, saturated or once or several times ethylenically unsaturated hydrocarbon group with 1 to 22 carbon atoms, optionally substituted by up to 3 alkyl substituents with 1 to 4 carbon atoms each,
- L denotes an arylene or stilbene group, optionally substituted by up to 3 alkyl sub stituents with 1 to 5 carbon atoms each, or denotes an alkylene group with 2 to 4 carbon atoms,
- A denotes —SO3M or —CO2M,
- M denotes H or an alkali metal atom,
- l, m and n irrespective of each other denote 0, 1, 2 or 3, and l+m+n≧1
- o denotes a number of from 1 to 6, and
- conventional constituents compatible with the urea derivative.

Urea derivatives of the general formula I,
- R—B—C(O)—NH—Ar(A)l-NH[—C(O)—NH-L(A)m-NH—C(O)—NH—Ar(A)n-NH]o—C(O)—B—R (I)
- in which
- R denotes a linear or branched alkyl group with 1 to 20 carbon atoms, or a cycloalkyl group with 3 to 10 carbon atoms,
- B denotes 0 or NH,
- Ar denotes an aromatic group, a stilbene group, or a linear, branched, or cyclic, saturated or once or several times ethylenically unsaturated hydrocarbon group with 1 to 22 carbon atoms, optionally substituted by up to 3 alkyl substituents with 1 to 4 carbon atoms each,
- L denotes an arylene or stilbene group, optionally substituted by up to 3 alkyl sub stituents with 1 to 5 carbon atoms each, or denotes an alkylene group with 2 to 4 carbon atoms,
- A denotes —SO3M or —CO2M,
- M denotes H or an alkali metal atom,
- l, m and n irrespective of each other denote 0, 1, 2 or 3, and l+m+n≧1
- o denotes a number of from 1 to 6,
- wherein the urea derivatives are utilized for avoiding the transfer of textile dyes from dyed textiles onto undyed or differently coloured textiles when they are jointly washed in aqueous solutions and/or for avoiding the modification of the colour appearance of dyed textiles when they are washed in aqueous solutions.
