The present invention relates to a laundry care composition comprising from 0.00001 wt% to 0.5 wt% mono-azo carboxylate dye having the structure of Formula IV: wherein D1 is an aromatic heterocyclic group; wherein D2 is a heteraromatic group; wherein R1 is independently selected from the group consisting of: (a) unsubstituted or substituted C1 to C12 alkyl chains, optionally the alkyl chains comprising ether (C-O-C), ester and/or amide links, optionally, the alkyl chains are substituted with -Cl, -Br, -CN, -NO2, -SO2CH3, -OH and mixtures thereof; and (b) (CH2CH2O)y'((CH2)wNH)z'Q'; wherein R2 is (CH2CH2O)y'((CH2)w'NH)z'Q'; wherein y and y' are independently selected integers from 0 to 39; wherein the sum of y + y' is in the range of from 3 to 30, preferably from 3 to 20, preferably from 3 to 10, preferably from 3 to 5; wherein w and w' are independently selected from 2 and 3; wherein z and z' are independently selected from 0 and 1; wherein z is 1 when y is 0; wherein z' is 1 when y' is 0; wherein Q and Q' are independently selected from the group consisting of H and Y; wherein at least one Q or Q' group is Y, preferably both Q and Q' are Y; wherein Y is an organic radical represented by Formula V wherein independently for each Y group: M is H or a charge balancing cation; m is 0 to 5, preferably 0, 1, 2 or 3, more preferably 0 or 1; n is 0 to 5, preferably 0, 1, 2 or 3, more preferably 0 or 1; the sum of m + n is 1 to 10, preferably 1, 2 or 3, more preferably 1 or 2; each R4 is independently selected from the group consisting of H, C3-18 or C4-C18 linear or branched alkyl, C3-18 or C4-C18 linear or branched alkenyl, and mixtures thereof, at least one R12 group is not H, and preferably the sum of carbon atoms in all the R12 groups is in the range of from 0.4(y + y') to 3.0(y + y'), preferably from 0.6(y + y') to 1.6(y + y'). |
