Abstract

The disclosure provides a liquid hand soap or body wash, comprising (i) a surfactant system comprising C 8-18 alkyl-ether sulfate, cocamidopropyl betaine (CAPB), and N-(2 hydroxyethyl) fatty acid amide; (ii) a polyethylene oxide-polypropylene oxide block copolymer; and (iii) one or more polyalkoxylated mono- or di-fatty acid esters or amides, the composition allowing reduced surfactant levels, while still having good rheological properties.

First claim

1 . A composition that is a liquid hand soap or body wash, comprising
a. surfactant system comprising C 8-18 alkyl-ether sulfate, cocamidopropyl betaine, and N-(2-hydroxyethyl) fatty acid amide; b. a polyethylene oxide-polypropylene oxide block copolymer; and c. one or more polyalkoxylated mono- or di-fatty acid esters or amides.

2 . The composition of claim 1 , wherein the C 8-18 alkyl-ether sulfate comprises a compound of formula CH 3 (CH 2 ) m CH 2 (OCH 2 CH 2 ) n OSO 3 X, wherein m is 6-16; n is 1-6; and X is Na or K.

3 . The composition of claim 1 , wherein the N-(2-hydroxyethyl) fatty acid amide comprises cocamide monoethanolamine.

4 . The composition of claim 1 , wherein the polyethylene oxide-polypropylene oxide block copolymer has a formula (EO)x(PO)y(EO)z with x=8-14, z=8-14 and y=16-26.

5 . The composition of claim 1 , wherein the one or more polyalkoxylated mono- or di-fatty acid esters or amides are selected from the group consisting of (C 2 -C 4 )alkoxylated mono(C 2 -C 3 )alkanol isostearamide, polyethoxylated glyceryl fatty acid esters, polyethoxylated esters of fatty acids and saccharides, and combinations thereof.

6 . The composition of claim 5 , wherein the wherein the one or more polyalkoxylated mono- or di-fatty acid esters or amides are selected from the group consisting of PPG-2 hydroxyethyl coco/isostearamide, PEG-18 glyceryl oleate/cocoate, PEG-7 glyceryl cocoate, PEG-120 methyl glucose dioleate, and combinations thereof.

7 . The composition of claim 6 , wherein the one or more polyalkoxylated mono- or di-fatty acid esters or amides comprise PEG-120 methyl glucose dioleate.

8 . The composition of claim 1 , wherein the surfactant system comprises sodium lauryl ether sulfate, cocamidopropyl betaine and cocamide monoethanolamine.

9 . The composition of claim 1 , wherein:
the surfactant system comprises sodium lauryl ether sulfate, cocamidopropyl betaine and cocamide monoethanolamine; the polyethylene oxide-polypropylene oxide block copolymer is (EO)x(PO)y(EO)z with x=8-14, z=8-14 and y=16-26; and the one or more polyalkoxylated mono- or di-fatty acid esters or amides are selected from the group consisting of PPG-2 hydroxyethyl coco/isostearamide, PEG-18 glyceryl oleate/cocoate, PEG-7 glyceryl cocoate, PEG-120 methyl glucose dioleate, and combinations thereof.

10 . The composition of claim 1 , further comprising a polyquaternium compound.

11 . The composition of claim 1 , further comprising at least 70 weight % water.

12 . The composition of claim 1 , wherein the total amount of surfactant is 5 to 9 weight %.

13 . The composition of claim 1 , wherein the amount of the C 8-18 alkyl-ether sulfate is 5.5 to 6.5 weight %.

14 . The composition of claim 1 , wherein the amount of the cocamidopropyl betaine is 1.5 to 2.4 weight %.

15 . The composition of claim 1 , wherein the amount of the N-(2-hydroxyethyl) fatty acid amide is 0.2 to 0.5 weight %.

16 . The composition of claim 1 , wherein the amount of the polyethylene oxide-polypropylene oxide block copolymer is 0.01 to 0.15 weight %.

7 . The composition of claim 1 , wherein the composition does not include an alkylpolyglucoside surfactant.

18 . The composition of claim 1 , wherein the zero-shear viscosity of the composition is 3,000-4,000 mPas.

19 . The composition of claim 1 , wherein the micelle relaxation time of the composition is less than 0.06 seconds.

70 . The composition of claim 1 , wherein the composition is a clear liquid hand soap.
