Claim 0:
1. A laundry care composition comprising a laundry care ingredient and a whitening agent,
wherein the whitening agent possesses a dispersion component value of the Hansen Solubility parameter of less than or equal to about 17 MPa0.5 
said whitening agent comprising:
(a) at least one chromophore component that comprises a thiophene colorant, and
(b) at least one polymeric component;

wherein the whitening agent is characterized by the following structure:, wherein R1 and R2 can independently be selected from:
a) [(CH2CR′HO)x(CH2CR″HO)yH]
wherein R′ is selected from the group consisting of H, CH3, CH2O(CH2CH2O)zH, and mixtures thereof; wherein R″ is selected from the group consisting of H, CH2O(CH2CH2O)zH, and mixtures thereof; wherein x+y≤5; wherein y≥1; and wherein z=0 to 5;

b) R1=alkyl, aryl or aryl alkyl and R2═[(CH2CR′HO)x(CH2CR″HO)yH]
wherein R′ is selected from the group consisting of H, CH3, CH2O(CH2CH2O)zH, and mixtures thereof; wherein R″ is selected from the group consisting of H, CH2O(CH2CH2O)zH, and mixtures thereof; wherein x+y≤10; wherein y≥1; and wherein z=0 to 5;

c) R1═[CH2CH2(OR3)CH2OR4] and R2═[CH2CH2(OR3)CH2OR4]
wherein R3 is selected from the group consisting of H, (CH2CH2O)zH, and mixtures thereof; and wherein z=0 to 10;
wherein R4 is selected from the group consisting of (C1-C16)alkyl, aryl groups, and mixtures thereof; and

d) wherein R1 and R2 can independently be selected from the amino addition product of styrene oxide, glycidyl methyl ether, isobutyl glycidyl ether, isopropylglycidyl ether, t-butyl glycidyl ether, 2-ethylhexylgycidyl ether, and glycidylhexadecyl ether, followed by the addition of from 1 to 10 alkylene oxide units.
