Abstract

This invention relates to a laundry care composition comprising a laundry care ingredient and a polymeric thiophene hueing agent.

First claim

We claim:

1. A laundry care composition comprising: (1) a laundry care ingredient comprising a carrier; (2) from 0.0001 wt % to 1.0 wt % of a polymeric thiophene hueing agent having the structure of Formula III:

and
(3) from 0.0001 wt % to 1.0 wt % of a polymeric thiophene hueing agent having the structure of Formula Y:

wherein the polymeric thiophene hueing agent of Formula III and the polymeric thiophene agent of Formula Y are present in a ratio from 1:3 to 3:1.

2. The laundry care composition of claim 1 , wherein the composition further comprises at least one of the following structures:

of salts thereof.

3. The laundry care composition of claim 1 , wherein each polymeric thiophene hueing agent is independently present in an amount in the range from 1 ppm to 500 ppm.

4. The laundry care composition of claim 1 , wherein the composition is present in powder form.

5. The laundry care composition of claim 1 , wherein the composition is present in liquid form.

6. The laundry care composition of claim 1 , wherein the composition is present in unit dose form.

7. The laundry care composition of claim 1 , wherein the composition is present in a multi-compartment unit dose form.

8. The laundry care composition of claim 1 , wherein the laundry care ingredient further comprises cationic polymers, surfactants, builders, chelating agents, dye transfer inhibiting agents, dispersants, enzymes, enzyme stabilizers, catalytic materials, bleach activators, hydrogen peroxide, sources of hydrogen peroxide, preformed peracids, polymeric dispersing agents, clay soil removal/anti-redeposition agents, brighteners, suds suppressors, dyes, pigments, coloring agents, perfumes, perfume delivery systems, structure elasticizing agents, fabric softeners, hydrotropes, and/or processing aids.

9. A method of treating a textile article comprising the steps of
(i) treating the textile article with the laundry care composition of claim 1 ,
and (ii) rinsing and drying the treated textile article.

10. The method of claim 9 , wherein the textile article is comprised of cellulose-containing fiber.

11. The method of claim 9 , wherein the step of treating the textile article is bleach-free.
