Abstract

Compositions, such as laundry detergent compositions, that include detersive surfactant and C4-C10 alkyl branched alcohol.

First claim

What is claimed is:

1. A laundry detergent composition comprising:
a) from about 10 wt % to about 50 wt % of a detersive surfactant, wherein the detersive surfactant comprises a combination of anionic and nonionic surfactant;
b) solvent comprising 2-ethylhexanol; 3,5,5-trimethyl-1-hexanol; 2-propylheptanol; or a mixture thereof; and
wherein the composition has a pH of from about 6.0 to about 8.9 and is free of bleach.

2. The laundry detergent composition according to claim 1 , wherein the solvent comprises 2-propyl heptanol.

3. The laundry detergent composition according to claim 1 , wherein the composition comprises solvent at a level of from about 0.1 wt % to about 10 wt %.

4. The laundry detergent composition according to claim 3 , wherein the composition comprises solvent at a level of from about 0.3 wt % to about 7.5 wt %.

5. The laundry detergent composition according to claim 4 , wherein the composition comprises solvent at a level of from about 0.5 wt % to about 5 wt %.

6. The laundry detergent composition according to claim 1 , wherein the detersive surfactant consists essentially of anionic surfactant, non-ionic surfactant, or mixtures thereof.

7. The laundry detergent composition according to claim 1 , wherein the anionic surfactant comprises linear alkyl benzene sulfonate and alkyl alkoxylated sulfate and the ratio of linear alkyl benzene sulfonate surfactant to alkyl alkoxylated sulphate surfactant is from about 0.1 to about 5.

8. The laundry detergent composition according to claim 7 , wherein the laundry composition comprises detersive surfactant at a level of from about 15 wt % to about 35 wt %.

9. The laundry detergent composition according to claim 1 , wherein the liquid laundry detergent composition comprises an external structurant or thickener selected from the group consisting of: non-polymeric crystalline, hydroxyl functional structurants; microfibrillated cellulose; uncharged hydroxyethyl cellulose; uncharged hydrophobically modified hydroxyethyl cellulose; hydrophobically modified ethoxylated urethanes; polyacrylates; hydrophobically modified non-ionic polyols; and mixtures thereof.

10. The laundry detergent composition according to claim 6 , wherein the laundry composition further comprises particles, selected from the group consisting of: beads, pearlescent agents, microcapsules, and mixtures thereof.

11. The laundry detergent composition according to claim 10 , wherein the laundry composition further comprises microcapsules.

12. The laundry detergent composition according to claim 1 , wherein the laundry composition comprises enzymes, chelants, additional non-aminofunctional organic solvents, or a mixture thereof.

13. A laundry detergent composition comprising:
from about 5% to about 25% by weight of the composition of anionic surfactant;
from about 2% to about 10% by weight of the composition of nonionic surfactant;
from about 0.5% to about 5% by weight of the composition of a solvent comprising 2-ethylhexanol, 3,5,5-trimethyl-1-hexanol, 2-propylheptanol, or a mixture thereof; wherein the composition is free of bleach.

14. The laundry detergent of claim 13 , wherein the anionic surfactant comprises an alkyl ethoxy sulfate surfactant, linear alkyl benzene sulfonate, or a combination thereof.

15. The laundry detergent of claim 14 , wherein the nonionic surfactant comprises a C12-C18 alkyl ethoxylate.

16. The laundry detergent of claim 15 , wherein the ratio by weight of linear alkyl benzene sulfonate to alkyl ethoxy sulfate surfactant is from about 0.6 to about 1.1.

17. The laundry detergent of claim 15 , further comprising citric acid and a fatty acid.

18. The laundry detergent of claim 17 , wherein the detergent comprises from about 6% to about 11%, by weigh of the detergent, of the anionic surfactant and from about 2% to about 5%, by weight of the detergent, of the nonionic surfactant.
