Abstract

Cleaning compositions including a non-ionic surfactant and a glycol ether are disclosed. These cleaning compositions are useful as liquid cleaners or de-greasers for animate surfaces, such as skin. The cleaning compositions provide improved cleaning and removal of soils without the use of certain VOCs.

Claims (20)

1. A skin cleaning composition comprising a hydrolyzed plant protein and a synergistic combination of a non-ionic surfactant and a glycol ether, wherein the composition comprises from about 2% to about 5% of the non-ionic surfactant and from about 2% to about 4% of the glycol ether, and wherein the composition has a surface cleaning index of about 1.

2. The skin cleaning composition of claim 1 wherein the composition has a pH of from about 3 to about 8.

3. The skin cleaning composition of claim 1 wherein the non-ionic surfactant has an HLB value of from about 6 to about 13.

4. The skin cleaning composition of claim 1 wherein the glycol ether is selected from the group consisting of propylene glycol methyl ether, dipropylene glycol methyl ether, tripropylene glycol methyl ether, propylene glycol methyl ether acetate, dipropylene glycol methyl ether acetate, propylene glycol n-butyl ether, dipropylene glycol n-butyl ether, tripropylene glycol n-butyl ether, ethylene glycol phenyl ether, ethylene glycol n-butyl ether, diethylene glycol n-butyl ether, trimethylene glycol n-butyl ether, diethylene glycol methyl ether, trimethylene glycol methyl enantiomer, and combinations thereof.

5. The skin cleaning composition of claim 1 wherein the glycol ether is dipropylene glycol n-butyl ether.

6. The skin cleaning composition of claim 1 wherein the non-ionic surfactant is an alcohol ethoxylate.

7. The skin cleaning composition of claim 1 wherein the composition is substantially free of d-limonene.

8. A cleaning composition comprising a non-ionic surfactant, a glycol ether, and a hydrolyzed plant protein, wherein the non-ionic surfactant is present in an amount of less than 6% by weight of the composition, and wherein the composition has a surface cleaning index of about 1 and a pH of from about 3 to about 8.

9. The cleaning composition of claim 8 wherein the glycol ether is selected from the group consisting of propylene glycol methyl ether, dipropylene glycol methyl ether, tripropylene glycol methyl ether, propylene glycol methyl ether acetate, dipropylene glycol methyl ether acetate, propylene glycol n-butyl ether, dipropylene glycol n-butyl ether, tripropylene glycol n-butyl ether, ethylene glycol phenyl ether, ethylene glycol n-butyl ether, diethylene glycol n-butyl ether, trimethylene glycol n-butyl ether, diethylene glycol methyl ether, trimethylene glycol methyl enantiomer, and combinations thereof.

10. The cleaning composition of claim 8 wherein the non-ionic surfactant is an alcohol ethoxylate.

11. The cleaning composition of claim 8 wherein the composition is substantially free of d-limonene.

12. A wipe comprising a fibrous substrate and a skin cleaning composition, wherein the composition comprises a hydrolyzed plant protein and a synergistic combination of a non-ionic surfactant and a glycol ether, wherein the composition comprises from about 2% to about 5% of the non-ionic surfactant and from about 2% to about 4% of the glycol ether, and wherein the composition has a surface cleaning index of about 1.

13. The wipe of claim 12 wherein the glycol ether is selected from the group consisting of propylene glycol methyl ether, dipropylene glycol methyl ether, tripropylene glycol methyl ether, propylene glycol methyl ether acetate, dipropylene glycol methyl ether acetate, propylene glycol n-butyl ether, dipropylene glycol n-butyl ether, tripropylene glycol n-butyl ether, ethylene glycol phenyl ether, ethylene glycol n-butyl ether, diethylene glycol n-butyl ether, trimethylene glycol n-butyl ether, diethylene glycol methyl ether, trimethylene glycol methyl enantiomer, and combinations thereof.

14. The wipe of claim 12 wherein the non-ionic surfactant is an alcohol ethoxylate.

15. The wipe of claim 12 wherein the composition is substantially free of d-limonene.

16. The skin cleaning composition of claim 1 further comprising a skin conditioning agent.

17. The skin cleaning composition of claim 1 further comprising a thickener.

18. The skin cleaning composition of claim 17 wherein the thickener is selected from group consisting of acrylates, gums, cellulosics, starches, polyethylene glycols, and combinations thereof.

19. The skin cleaning composition of claim 1 wherein the composition comprises about 3% of the non-ionic surfactant and about 3% of the glycol ether.

20. The wipe of claim 12 wherein the composition comprises about 3% of the non-ionic surfactant and about 3% of the glycol ether.
