Abstract

The present disclosure relates to detergent compositions that comprise renewable components and exhibit good performance, as compared to both traditional detergent formulations that contain non-renewable ingredients and known detergent formulations that contain renewable components.

First claim

What is claimed is:

1. A laundry detergent composition comprising: from about 1% to about 20% by weight of alkyl ether sulfate of the formula R 1 —(OCH 2 CH 2 ) x —O—SO 3 M, wherein R 1 is a non-petroleum derived, linear or branched fatty alcohol consisting of even numbered carbon chain lengths of from about C 8 to about C 20 , and wherein x is from about 0.5 to about 8, and where M is an alkali metal or ammonium cation; from about 1% to about 15% by weight of fatty alcohol ethoxylate of formula R 2 —(OCH 2 CH 2 ) y —OH, wherein R 2 is a non-petroleum derived, linear or branched fatty alcohol consisting of even numbered carbon chain lengths of from about C 10 to about C 18 , and wherein y is from about 0.5 to about 15; from about 0.1% to about 5% by weight of amine oxide; from about 0.1% to about 5% of a cleaning polymer, from about 1% to about 15% by weight of a solvent comprising 1,2-propanediol; and water; wherein the composition is substantially free of dye and brightener; and wherein the laundry detergent composition comprises a polyhydric alcohol selected from the group consisting of 2,3-butanediol, 2,3-pentanediol, 2,4-pentanediol, 1,2-butanediol, 2,3-hexandiol, 1,5-pentanediol, and mixtures thereof.

2. The laundry detergent composition of claim 1 wherein the composition comprises from about 0.01% to about 0.1% of the polyhydric alcohol.

3. The laundry detergent composition of claim 1 wherein the composition is substantially free of linear or branched alkyl benzene sulfonates.

4. The laundry detergent composition of claim 1 wherein the composition is substantially free of monoethanolamine.

5. The laundry detergent composition of claim 1 wherein the composition comprises an enzyme selected from the group consisting of lipase, cellulase, protease, amylase, and mixtures thereof.

6. The laundry detergent composition of claim 1 wherein the cleaning polymer is selected from the group consisting of modified or unmodified cellulosic polymer, polycarboxylates, polyamines, oligoamines, triamines, diamines, pentamines, tetraamines, alkoxylated polyalkyleneimines, soil release polymers, and mixtures thereof.

7. The laundry detergent composition of claim 1 wherein the cleaning polymer comprises one or more alkoxylated polyalkyleneimines.

8. The laundry detergent composition of claim 1 wherein the composition comprises an adjunct.

9. The laundry detergent composition of claim 1 wherein the composition comprises an adjunct selected from the group consisting of a structurant, a builder, a fabric softening agent a polymer or an oligomer, an enzyme, an enzyme stabilizer, a bleach system, a brightener, a hueing agent, a chelating agent, a suds suppressor, a conditioning agent, a humectant, a perfume, a perfume microcapsule, a filler or carrier, an alkalinity system, a pH control system, a buffer, an alkanolamine, a solvent, and mixtures thereof.

10. The laundry detergent composition of claim 1 wherein the composition comprises an adjunct selected from one or perfume delivery systems.

11. The laundry detergent composition of claim 1 wherein the composition comprises a perfume delivery system selected from the group consisting of perfume microcapsule (PMC), amine-assisted perfume delivery system (AAD), polyacrylate capsule, and sulfur-containing pro-perfume compound, and mixtures thereof.

12. The laundry detergent composition of claim 1 wherein the composition comprises an adjunct selected from thiodamascone.

13. A transparent or translucent liquid laundry detergent composition in a transparent bottle, wherein the composition comprises from about 1% to about 20% by weight of alkyl ether sulfate of the formula R 1 —(OCH 2 CH 2 ) x —O—SO 3 M, wherein R 1 is a non-petroleum derived, linear or branched fatty alcohol consisting of even numbered carbon chain lengths of from about C 8 to about C 20 , and wherein x is from about 0.5 to about 8, and wherein M is an alkali metal or ammonium cation; from about 1% to about 15% by weight of fatty alcohol ethoxylate of formula R 2 —(OCH 2 CH 2 ) y —OH, wherein R 2 is a non-petroleum derived, linear or branched fatty alcohol consisting of even numbered carbon chain lengths of from about C 10 to about C 18 , and wherein y is from about 0.5 to about 15; from about 0.1% to about 5% by weight of amine oxide; from about 0.1% to about 5% of a cleaning polymer; from about 1% to about 15% by weight of a solvent comprising 1,2-propanediol; and water; where the transparent or translucent composition has about 50% transmittance or greater of light using 1 cm cuvette at wavelength of 410-800 nanometers; and where the transparent bottle has light transmittance of greater than 25% at wavelength of about 410-800 nm.

14. The transparent or translucent liquid laundry detergent composition in the transparent bottle of claim 13 wherein the composition is substantially free of dye and brightener.

15. The transparent or translucent liquid laundry detergent composition in the transparent bottle of claim 13 wherein the composition is substantially free of monoethanolamine.

16. The transparent or translucent liquid laundry detergent composition in the transparent bottle of claim 13 wherein the composition is substantially free of linear or branched alkyl benzene sulfonates.

17. A method of laundering colored fabric which comprises the steps of: providing a detergent composition where the composition comprises from about 1% to about 20% by weight of alkyl ether sulfate of the formula R 1 —(OCH 2 CH 2 ) x —O—SO 3 M, wherein R 1 is a non-petroleum derived, linear or branched fatty alcohol consisting of even numbered carbon chain lengths of from about C 8 to about C 20 , and wherein x is from about 0.5 to about 8, and wherein M is an alkali metal or ammonium cation; from about 1% to about 15% by weight of fatty alcohol ethoxylate of formula R 2 —(OCH 2 CH 2 ) y —OH, wherein R 2 is a non-petroleum derived, linear or branched fatty alcohol consisting of even numbered carbon chain lengths of from about C 10 to about C 18 , and wherein y is from about 0.5 to about 15; from about 0.1% to about 5% by weight of amine oxide; from about 0.1% to about 5% of a cleaning polymer; from about 1% to about 15% by weight of a solvent comprising 1,2-propanediol; a polyhydric alcohol selected from the group consisting of 2,3-butanediol, 2,3-pentanediol, 2,4-pentanediol, 1,2-butanediol, 2,3-hexandiol, 1,5-pentanediol, and mixtures thereof; and water, where the composition is substantially free of brightener and monoethanolamine; diluting a dose of the detergent composition in water by a factor of greater than 500 to obtain a wash liquor which comprises 0.8 to 0.035 g/L of surfactant; washing the colored fabric with the wash liquor so formed, where the chlorine scavenging efficiency is at least about 90% at an initial free chlorine concentration of 2.4 ppm.

18. The method of claim 17 wherein the composition is substantially free of dye.

19. A laundry detergent composition comprising:
from about 1% to about 20% by weight of alkyl ether sulfate of the formula R 1 —(OCH 2 CH 2 ) x —O—SO 3 M, wherein R 1 is a non-petroleum derived, linear or branched fatty alcohol consisting of even numbered carbon chain lengths of from about C 8 to about C 20 , and wherein x is from about 0.5 to about 8, and where M is an alkali metal or ammonium cation;
