Abstract

Provided herein are solid textile treating compositions; compositions containing colorants stabilized with one or more colorant stabilizers; compositions containing colorants that do not need to be stabilized by one or more colorant stabilizers; solid wash cycle conditioning agents; liquid textile treating compositions; cleaning agent compositions containing these; methods of making these; methods of treating textiles with these; textiles treated by these; containers containing the compositions; and methods of visually designating when a composition has reached or passed its pull date.

First claim

What is claimed is:

1. A unit dose solid textile-treating article, comprising:
a water-soluble single-chamber container; and
at least one solid textile-treating composition, which comprises:
(a) a water-soluble core comprising a water-soluble carrier;
wherein the water-soluble core is in particle form having an average particle size from about 0.1 mm to about 50 mm;

(b) a coating that at least partially covers the water-soluble core, the coating comprising:
(i) a water-soluble polymer;
(ii) a colorant; and
(iii) a colorant stabilizer that is an acid having a molecular weight of 1000 daltons or less;
wherein the colorant stabilizer is formic acid, an acetic acid, a propanoic acid, a butanoic acid, a pentanoic acid, a hexanoic acid, a heptanoic acid, a octanoic acid, a nonanoic acid, a decanoic acid, a cyclopropyl carboxylic acid, a cyclobutyl carboxylic acid, a cyclopentyl carboxylic acid, a cyclohexyl carboxylic acid, a cycloheptyl carboxylic acid, a cyclooctyl carboxylic acid, a cyclononylcarboxylic acid, a cyclodecanoyl carboxylic acid, a lactic acid, a pyruvic acid, a phenol, or a combination thereof; and

(c) a flow aid mixed into the coating such that the flow aid is partially or fully exposed on an outer surface of the coating;
wherein the at least one solid textile-treating composition does not contain a polysaccharide;

wherein the water-soluble single-chamber container contains the at least one solid textile-treating composition.

2. The unit dose solid textile-treating article of claim 1 , wherein said single-chamber container is a formed, sealed pouch produced from a water-soluble polymer or film.

3. The unit dose solid textile-treating article of claim 1 , wherein the coating further comprises a perfume.

4. The unit dose solid textile-treating article of claim 3 , wherein said water-soluble carrier comprises solar salt with yellow prussiate of soda.

5. The unit dose solid textile-treating article of claim 3 , wherein the unit dose solid textile-treating article further comprises water.

6. The unit dose solid textile-treating article of claim 3 , wherein at least some of the perfume is encapsulated.

7. The unit dose solid textile-treating article of claim 6 , wherein at least some of the encapsulated perfume is encapsulated in a microcapsule.

8. The unit dose solid textile-treating article of claim 1 , wherein the coating does not comprise a perfume.

9. The unit dose solid textile-treating article of claim 1 , wherein the flow aid comprises a fabric softener.

10. The unit dose solid textile-treating article of claim 9 , wherein the fabric softener is a polysiloxane, a textile-softening clay, a cationic polymer, or any combination thereof.

11. The unit dose solid textile-treating article of claim 1 , wherein the water-soluble carrier is sodium chloride, potassium chloride, calcium chloride, magnesium chloride, sodium sulfate, potassium sulfate, magnesium sulfate, sodium carbonate, potassium carbonate, sodium hydrogen carbonate, potassium hydrogen carbonate, sodium acetate, potassium acetate, sodium citrate, potassium citrate, sodium tartrate, potassium tartrate, potassium sodium tartrate, calcium lactate, water glass, sodium silicate, potassium silicate, dextrose, fructose, galactose, isoglucose, glucose, sucrose, raffinose, isomalt, xylitol, candy sugar, coarse sugar, or any combination thereof.

12. The unit dose solid textile-treating article of claim 1 , wherein the coating completely surrounds the water-soluble core.

13. The unit dose of solid textile-treating article of claim 1 , wherein the water-soluble polymer is a polyalkylene glycol, a polyethylene glycol, a polyethylene terephthalate, a polyvinyl alcohol, or any mixture thereof.

14. The unit dose solid textile-treating article of claim 1 , wherein the colorant in the composition changes hue or becomes substantially colorless in the absence of the colorant stabilizer after a time period ranging from about 2 weeks to about 3 months.

15. A unit dose solid textile-treating article, comprising:
a water-soluble single-chamber container; and
at least one solid textile-treating composition, which comprises:
(a) a water-soluble core comprising a water-soluble carrier;
wherein the water-soluble core is in particle form having an average particle size from about 0.1 mm to about 50 mm;

(b) a coating that at least partially covers the water-soluble core, the coating comprising:
(i) a water-soluble polymer;
(ii) a colorant; and
(iii) a colorant stabilizer having a molecular weight of 1000 daltons or less;

(c) a flow aid mixed into the coating such that the flow aid is partially or fully exposed on an outer surface of the coating;
wherein the colorant stabilizer is an alkyl carboxylic acid, a cycloalkyl carboxylic acid, heterocycloalkyl carboxylic acid, an aryl carboxylic acid, heteroaryl carboxylic acid, a cycloalkyl alkyl carboxylic acid, an aryl alkyl carboxylic acid, a heterocycloalkyl alkyl carboxylic acid, a heteroaryl alkyl carboxylic acid, or any combination thereof;

wherein the at least one solid textile-treating composition does not contain a polysaccharide;

wherein the water-soluble single-chamber container contains the at least one solid textile-treating composition.

16. The unit dose solid textile-treating article of claim 1 , wherein the flow aid comprises an inorganic alkali metal salt, an inorganic alkaline earth metal salt, a silicate, an aluminosilicate, an amorphous silica, or any combination thereof.

17. A method of delivering a fragrance to a fabric, comprising contacting said fabric with the unit dose textile-treating article of claim 3 in a wash cycle, and drying said fabric.
