Abstract

Fabric and home care products including sulfatized esteramines obtainable by a process comprising step a), wherein at least one alcohol containing at least two hydroxy groups (compound (A)) is reacted with at least one lactam (compound (B)) and with sulfuric acid (compound (C)).

First claim

What is claimed is:

1 . A fabric and home care product comprising a surfactant system and a sulfatized esteramine obtainable by a process comprising step a):
a) reacting at least one compound (A) comprising an alcohol containing at least two hydroxy groups, compound B comprising at least one lactam; and compound (C) comprising sulfuric acid; wherein the sulfatized esteramine has a structure according to Formula (I) and salts thereof,

wherein independently from each other
n being an integer from about 1 to about 12,
m being an integer for each repetition unit n independently selected from about 0 to about 12;
p being an integer from about 0 to about 12,
o being an integer for each repetition unit p independently selected from about 0 to about 12;
r being an integer from about 0 to about 12,
q being an integer for each repetition unit r independently selected from about 0 to about 12;
s, t, u and v being an integer from about 0 to about 100;
A 1 , A 2 , A 3 , and A 4 are independently from each other and independently for each repetition unit s, t, u, or v, selected from the list consisting of alkyleneoxy group, such A-units stem from the reaction of one alcohol with at least two hydroxy groups with C 2 -C 22 alkylene oxides,
wherein for s, t, u, and/or v equal to 1 the oxygen atom of the A 1 , A 2 , A 3 , and A 4 group is bound to the B group and the following A 1 , A 2 , A 3 , and A 4 groups are always bound via the oxygen atom to the previous A 1 , A 2 , A 3 , and A 4 group,
B 1 , B 2 , B 3 , and B 4 are independently from each other selected from the group consisting of a bond, linear C 1 to C 12 alkanediyl groups, and branched C 1 to C 12 alkanediyl groups,
such B-units are given by the molecular structure of one alcohol with at least two hydroxy groups,
R 1 , R 2 , R 3 R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , R 11 and R 12 being independently for each repetition unit selected from the group consisting of H, linear alkyl, branched alkyl, and cycloalkyl; such R-units are given by the molecular structure of one alcohol with at least two hydroxy groups,
Z 1 , and/or Z 2 , and/or Z 3 , and/or Z 4 , independently for each repetition unit n, p, and r, are selected from the group consisting of OH, and OSO 3 − , and —OSO 3 H and a compound according to Formula (II), wherein said compound according to Formula (II) connects to the compound according to Formula (I) via the bond labeled with *, such Z-units stem from the reaction of one alcohol with at least two hydroxy groups with at least one lactam and with sulfuric acid,
with the proviso that at least about 10 mol % to about 50 mol % of the substituents Z 1 , and/or Z 2 , and/or Z 3 , and/or Z 4 , are a compound according to Formula (II), and at least about 10 mol % to about 50 mol % of the substituents Z 1 , and/or Z 2 , and/or Z 3 , and/or Z 4 , are a group consisting of OSO 3 − , or —OSO 3 H, and about 0 mol % to about 80 mol % of the substituents Z 1 , and/or Z 2 , and/or Z 3 , and/or Z 4 , are OH,

with independently from each other
w being an integer from about 0 to about 12,
R 13 , R 14 R 15 , R 16 , R 17 , and R 18 independently being selected from the group consisting of H, linear alkyl, branched alkyl, and cycloalkyl; such R-units stem from the lactam.

2 . The fabric and home care product according to claim 1 , wherein the product comprises from about 1% to about 70%, by weight of the product, of the surfactant system.

3 . The fabric and home care product according to claim 1 , wherein the surfactant system is selected from the group consisting of anionic surfactants, nonionic surfactants, cationic surfactants, zwitterionic surfactants, amphoteric surfactants, and mixtures thereof.

4 . The fabric and home care product according to claim 1 , wherein the product comprises from about 0.1% to about 5%, by weight of the product, of the sulfatized esteramine.

5 . The fabric and home care product according to claim 1 , wherein the product is a laundry detergent composition or a dishwashing detergent composition.
