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. An aqueous laundry care composition comprising:
(a) a laundry care ingredient;
(b) from 0.0001 wt % to 1.0 wt % of a polymeric thiophene hueing agent having the structure of Formula III:

(c) water in an amount in the range from 25% to 75% based on total laundry care composition weight.

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

or salts thereof.

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

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

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

6. The aqueous laundry care composition of claim 1 , wherein the laundry care ingredient is selected from the group consisting of cationic polymers, surfactants, builders, chelating agents, dye transfer inhibiting agents, dispersants, enzymes, and 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, carriers, hydrotropes, and processing aids.

7. The aqueous laundry care composition of claim 1 , wherein the composition imparts a desired hue to a textile article with a relative hue angle >270.

8. The aqueous laundry care composition of claim 1 , wherein the composition imparts a desired hue to a textile article with a relative hue angle in the range from 270 to 310.

9. The aqueous laundry care composition of claim 1 , wherein the composition imparts a desired hue to a textile article with a relative hue angle in the range from 290 to 310.

10. A method of treating a textile article to improve the visual appearance of the article comprising the steps of (1) providing a textile article, and (2) exposing the textile article to the aqueous laundry care composition of claim 1 .

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

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