Abstract

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

First claim

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

wherein R is selected from a saturated or unsaturated, linear or branched, C 8 -C 20 alkyl group, 0≦n≦10, and the average value of n is about 1, wherein less than about 7% by weight of the alcohol ethoxylate are ethoxylates having n≧3 and less than about 35% by weight of the alcohol ethoxylate are ethoxylates having n=0.

2 . The composition of claim 1 , wherein said alcohol ethoxylate is sulfated.

3 . A composition comprising 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 0≦n≦10, and where the average value of n is about 2, where from about 9% to about 13% by weight of the alcohol ethoxylate are ethoxylates having n≧4 and from about 9% to about 13% by weight of the alcohol ethoxylate are ethoxylates having n=0.

4 . The composition of claim 3 , wherein said alcohol ethoxylate is sulfated.

5 . A composition comprising alcohol ethoxylate of formula (I):

where R is selected from a saturated or unsaturated, linear or branched, C 8 -C 20 alkyl group, where 0≦n≦10, and where the average value of n is about 3, where about 1% to about 5% by weight of the alcohol ethoxylate are ethoxylates having n=0.

6 . The composition of claim 5 , wherein said alcohol ethoxylate is sulfated.

7 . The composition of claim 1 comprising from about 1% to about 10% by weight of the composition of a C1-14 sulfonic acid.

8 . The composition of claim 3 comprising from about 1% to about 10% by weight of the composition of a C1-14 sulfonic acid.

9 . The composition of claim 5 comprising from about 1% to about 10% by weight of the composition of a C1-14 sulfonic acid.

10 . The composition of claim 1 comprising from about 1% to about 2% by weight of the composition of methane sulfonic acid and from about 0.1% to about 2% by weight of the composition of an alkyl ether.

11 . The composition of claim 1 comprising from about 2% to about 6% by weight of the composition of dodecyl benzene sulfonic acid and from about 0.1% to about 4% by weight of the composition of an impurity selected from the group consisting of alkyl ethers, glycols, and ethoxylated sulfonates.

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

13 . 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.

14 . A concentrated composition comprising from about 1% to about 10% by weight of the composition of a C1-14 sulfonic acid and from about 50% to about 99% by weight of a narrow range alcohol ethoxylate having an average degree of ethoxylation ranging from about 1 to about 10.

15 . A concentrated composition comprising from about 1% to about 10% by weight of the composition of a C1-14 sulfonic acid and from about 10% to about 85% by weight of a narrow range alcohol ethoxy sulfate having an average degree of ethoxylation ranging from about 1 to about 10.

16 . A composition comprising an alcohol ethoxylate of formula (I):

wherein R is a C 14 or C 15 alkyl group, 0≦n≦10, and the average value of n is about 2.5, wherein less than about 6% by weight of the alcohol ethoxylate are ethoxylates having n≧6 and less than about 6% by weight of the alcohol ethoxylate are ethoxylates having n=0.

17 . The composition of claim 16 , wherein said alcohol ethoxylate is sulfated.
