Abstract

Fabric conditioning compositions comprising a fabric care active and a hueing dye, wherein the hueing dye exhibits a hueing efficiency of at least about 20 according to the Hueing Efficiency Test method; and a Wash Removal Value from about 50% to about 98%, are useful in mitigating the discoloration of white and other light colored fabrics.

Claims (15)

1. A fabric conditioning composition comprising:

(a) a fabric care active;

(b) a hueing dye, wherein the hueing dye has:

(i) a hueing efficiency value greater than about 20, and

(ii) a wash removal value from about 50% to about 98%;

(c) a brightener;

(d) a Stain Reducing Agent having a staining index less than about 90 , said Stain Reducing Agent comprising an ethoxylated monoalkyl quaternary surfactant.

2. The composition of claim 1 , wherein the brightener is chosen from at least one of the following: Disodium 4,4′-bis-(2-sulfostyryl) biphenyl; Benzenesulfonic acid, 2,2′-(1,2-ethenediyl)bis[5-[4-[(2-hydroxyethyl)methylamino]-6-(phenylamino)-1,3,5-triazin-2-y]amino]-, disodium salt; Disodium 4,4′-bis {[4anilino-6-[bis(2-hydroxyethyl)amino-s-triazin-2yl]-amino}-2,2′-stilbenedisulfonate; Disodium 4,4′-bis[(4-anilino-6-(N-2-hydroxyethyl-N-methylamino)-s-triazine-2-yl)amino]2,2′-stilbenedisulfonate; Disodium 4,4′-bis{[4-anilino-6methylamino-s-triazin-2-yl]amino}-2,2′-stilbenedisulfonate; Disodium 4,4″-bis[4,6-di-anilino-s-triazin-2-yl]-2,2′-stilbenedisulfonate; Disodium 4,4′-bis{[4-anilino-6-morpholino-s-triazin-2-yl}-amino}-2,2′-stilbenedisulfonate.

3. The composition of claim 1 , wherein the brightener is Disodium 4,4′-bis-(2-sulfostyryl) biphenyl and wherein the Stain Reducing Agent is an ethoxylated monoalkyl quaternary compound.

4. The composition of claim 3 , wherein the composition has a Reflectance K/S Value of from about 560 nm to about 620 nm.

5. The composition of claim 4 , wherein the hueing dye level is from about 0.00001% to about 1% by weight of the composition.

6. The composition of claim 5 , wherein the brightener level is from about 0.01% to about 5% by weight of the composition.

7. The composition of claim 6 , further comprising a cationic polymer.

8. The composition of claim 7 , wherein the cationic polymer is a cationic polysaccharide.

9. The composition of claim 8 , wherein the cationic polysaccharide is a cationic starch.
