Abstract

A detergent composition can include a cleaning composition including: (a) linear alkyl benzene sulphonate surfactant; (b) alkyl ethoxylated sulphate surfactant; and (c) alkoxylated polymer.

First claim

What is claimed is:

1. A cleaning composition comprising:
(a) linear alkyl benzene sulphonate surfactant;
(b) alkyl ethoxylated sulphate surfactant;
(c) alkoxylated polymer comprising a core structure selected from:
(i) linear oligoamine represented by structure below

wherein each L is independently —(C m H 2m )—, wherein the index m is an integer from about 2 to about 6; and wherein the index n is an integer of from about 0 to about 10; and
(ii) cyclic amine represented by structure below:

wherein R 1 -R 6 are independently selected from H, —NH 2 , —(C 1 -C 4 )NH 2 , linear or branched alkyl or alkenyl having from about 1 to about 10 carbon atoms, wherein at least two of R 1 -R 6 are selected from —NH 2 and —(C 1 -C 4 )NH 2 or combination, and wherein the index n is an integer of from about 1 to about 3;

wherein at least one of the active H in —NH— and/or —NH 2 moieties of the polymer core is modified with an alkylene oxide moiety selected from ethylene oxide (EO), propylene oxide (PO), butylene oxide (BO) and mixtures thereof,
wherein EO/PO/BO alkylene oxide moiety substituents are arranged randomly or in block configuration, and wherein the average number of EO (x), average number of PO (y), and average number of BO (z) per active H in —NH— and/or —NH 2 moieties of the polymer core structure are determined by the following:
(a) when the polymer core structure is linear oligoamine according to formula (i),then y+z is more than about 2, and the ratio of (y+z)/x is from about 70:30 to about 100:0; and
(b) when the polymer core structure is a cyclic amine according to formula (iii), then y is from about 4 to about 50, and x and z are from about 0 to about 50.

2. A cleaning composition according to claim 1 , wherein the composition comprises a non-ionic surfactant.

3. A cleaning composition according to claim 2 , wherein the non-ionic surfactant is an alkyl ethoxylated alcohol having an average degree of ethoxylation of from about 1 to about 10.

4. A cleaning composition according to claim 1 , wherein the alkyl ethoxylated sulphate surfactant has an average degree of ethoxylation of from about 0.1 to about 5.

5. A composition according to claim 1 , wherein the weight ratio of linear alkyl benzene sulphonate surfactant to alkyl ethoxylated sulphate surfactant is greater than about 2.0:1.
