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 composition comprising from about 1% to about 10% by weight of the composition of a C 1-14 sulfonic acid and 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 1, 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 free alcohol.

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

3. A detergent composition comprising the composition of claim 2 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 dishwashing detergent, a hard surface cleaner, a fabric softener composition, and mixtures thereof.

4. 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.

5. 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.

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

7. 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 dishwashing detergent, a hard surface cleaner, a fabric softener composition, and mixtures thereof.
