Abstract

The present invention relates generally to narrow range alcohol alkoxylates and derivatives thereof, such as alkyl ether sulfates.

First claim

What is claimed is:

1. A detergent composition comprising:
a. an alcohol ethoxylate of formula (I):

where R is selected from a saturated or unsaturated, linear or branched, C 8 -C 20 alkyl group, where greater than 90% of n is 0≤n≤15, and where the average value of n is between about 4 and about 14, wherein the alcohol ethoxylate of formula (I) comprises between 10% and about 20% by weight of the alcohol ethoxylate of ethoxylates having n=8; and
b. an additional surfactant;
wherein the total amount of surfactant is from about 5% to about 60%, by weight of the detergent composition.

2. The composition of claim 1 , wherein the alcohol ethoxylate of formula (I) comprises an average value of n between about 5 and about 12.

3. The composition of claim 1 , wherein the alcohol ethoxylate of formula (I) comprises an average value of n between about 8 and about 11.

4. The composition of claim 1 , wherein the alcohol ethoxylate of formula (I) comprises less than about 10% by weight of the alcohol ethoxylate of ethoxylates having n<7.

5. The composition of claim 1 , wherein the alcohol ethoxylate of formula (I) comprises between about 30% by weight and about 55% by weight of the alcohol ethoxylates of ethoxylates having n=9-10.

6. The composition of claim 1 , wherein the alcohol ethoxylate of formula (I) comprises greater than 80% by weight of the alcohol ethoxylate of ethoxylates having n>7.

7. The composition of claim 1 , wherein the composition comprises between about 35% by weight and about 75% by weight of the alcohol ethoxylates of ethoxylates having n=8-11.

8. The composition of claim 1 , wherein said alcohol ethoxylate is derived from a natural alcohol, a synthetic alcohol, or a mixture thereof.

9. A detergent composition comprising the composition of claim 1 , wherein said detergent composition is a form selected from the group consisting of a granular detergent, a bar-form detergent, a liquid laundry detergent, a gel detergent, a single-phase or multi-phase unit dose detergent, a detergent contained in a single-phase or multi-phase or multi-compartment water soluble pouch, a liquid hand dishwashing composition, a laundry pretreat product, a detergent contained on or in a porous substrate or nonwoven sheet, a automatic dish-washing detergent, a hard surface cleaner, a fabric softener composition, and mixtures thereof.

10. A detergent composition comprising:
a. an alcohol ethoxylate of formula (I):

where R is selected from a saturated or unsaturated, linear or branched, C 8 -C 20 alkyl group, where greater than 90% of n is 0≤n≤15, and where the average value of n is between about 8 and about 11; wherein about 30% to about 55%, by weight of the alcohol ethoxylate have an n from about 9 to about 10 and less than 10% by weight of the alcohol ethoxylate have an n<7; and
b. an additional surfactant;
wherein the total amount of surfactant is from about 5% to about 60%, by weight of the detergent composition.

11. The composition of claim 10 , wherein the alcohol ethoxylate of formula (I) comprises about 10% to about 20% by weight of the alcohol ethoxylate where n=8.

12. A detergent composition comprising:
a. an alcohol ethoxylate of formula (I):

where R is selected from a saturated or unsaturated, linear or branched, C 8 -C 20 alkyl group, where greater than 90% of n is 0≤n≤15, and where the average value of n is between about 4 and about 14, wherein less than about 20% by weight of the alcohol ethoxylate are ethoxylates having n<8 and the composition comprises between about 35% by weight and about 75% by weight of the alcohol ethoxylates of ethoxylates having n=8-11; and
b. an additional surfactant;
wherein the total amount of surfactant is from about 5% to about 60%, by weight of the detergent composition.

13. The composition of claim 12 , wherein the alcohol ethoxylate of formula (I) comprises between 10% and about 20% by weight of the alcohol ethoxylate of ethoxylates having n=8.

14. The composition of claim 12 , wherein the alcohol ethoxylate of formula (I) comprises an average value of n between about 5 and about 12.

15. The composition of claim 12 , wherein the alcohol ethoxylate of formula (I) comprises an average value of n between about 8 and about 11.

16. The composition of claim 12 , wherein the alcohol ethoxylate of formula (I) comprises less than about 10% by weight of the alcohol ethoxylate of ethoxylates having n<7.

17. The composition of claim 12 , wherein the alcohol ethoxylate of formula (I) comprises between about 30% by weight and about 55% by weight of the alcohol ethoxylates of ethoxylates having n=9-10.

18. The composition of claim 12 , wherein the alcohol ethoxylate of formula (I) comprises greater than 80% by weight of the alcohol ethoxylate of ethoxylates having n>7.
