Abstract

A fabric and home care product comprising a surfactant of formula Iwherein Ar represents an aryl group;R1 is H or a group of formula OR wherein R is H or SO3X wherein X is an alkali metal, alkali-earth metal or ammonium of general formula R′R″R′″R″″N wherein R′, R″, R′″ and R″″ are independently chosen from hydrogen or a hydrocarbyl group which can be optionally substituted and/or interrupted by one or more heteroatom containing groups; R2 is H or SO3X wherein X is an alkali metal, alkali-earth metal or ammonium of general formula R′R″R′″R″″N wherein R′, R″, R′″ and R″″ are independently chosen from hydrogen or a hydrocarbyl group which can be optionally substituted and/or interrupted by one or more heteroatom containing groups; with the proviso that R1 and R2 are different groups when R2 is SO3X, R1 is H or OR with R is H when R2 is H, R1 is OR with R is SO3X R3 is a C6-C16 aliphatic group.

First claim

What is claimed is:

1 . A fabric and home care product comprising a surfactant of formula I

wherein Ar represents an aryl group;
R 1 is H or a group of formula OR wherein R is H or SO 3 X wherein X is an alkali metal, alkali-earth metal or ammonium of general formula R′R″R′″R″″N wherein R′, R″, R′″ and R″″ are independently chosen from hydrogen or a hydrocarbyl group which can be optionally substituted and/or interrupted by one or more heteroatom containing groups;
R 2 is H or SO 3 X wherein X is an alkali metal, alkali-earth metal or ammonium of general formula R′R″R′″R″″N wherein R′, R″, ′″ and R″″ are independently chosen from hydrogen or a hydrocarbyl group which can be optionally substituted and/or interrupted by one or more heteroatom containing groups;
with the provisio that
R 1 and R 2 are different groups
when R 2 is SO 3 X, R 1 is H or OR with R is H
when R 2 is H, R 1 is OR with R is SO 3 X
R 3 is a C 6 -C 16 aliphatic group.

2 . The fabric and home care product of claim 1 , wherein Ar is a phenyl group.

3 . The fabric and home care product of claim 2 , wherein X is sodium.

4 . The fabric and home care product of claim 1 , wherein
R 1 is OSO 3 X and R 2 is H.

5 . The fabric and home care product of claim 1 , wherein
R 1 is OH R 2 is SO 3 X.

6 . The fabric and home care product of claim 1 , wherein
R 1 is H and R 2 is SO 3 X.

7 . The fabric and home care product of claim 1 , wherein
R 3 is a C 10 -C 16 aliphatic group.

8 . The fabric and home care product of claim 1 , wherein
R 3 is a C 14 -C 16 aliphatic group.

9 . The fabric and home care product of claim 1 , wherein the product is hard surface cleaner, a laundry detergent, air freshener, dish washing detergent, fabric conditioner, hard surface cleaner, laundry additive, rinse additive, or a combination thereof.

10 . The fabric and home care product of claim 1 , wherein the product comprises from about 5% to about 65% by weight of the product, of the surfactant.
