Abstract

Foaming alcohol compositions with selected dimethicone surfactants are disclosed. The dimethicone surfactants are PEG-8 to PEG-12 linear dimethicone surfactants and in particular PEG-10 linear dimethicone surfactant. The compositions are useful as antimicrobial products and in particular handcare or skincare products.

Claims

1. A non-aerosol foaming antimicrobial composition comprising:

a) a foaming agent comprising a PEG-8 to PEG-12 linear dimethicone surfactant having an average foam height of greater than 20 mm;

b) an alcohol; and

c) water

wherein there is less than about 5 wt. % of an additional surfactant.

2. The composition of claim 1 wherein said alcohol is a lower chain alcohol.

3. The composition of claim 1 wherein said lower chain alcohol is in an amount of from about 50 to about 90 wt. % of said composition.

4. The antimicrobial composition of claim 1, further comprising from about 0.01 to about 20 wt. % of a skin conditioner.

5. The antimicrobial composition of claim 1, wherein the foam agent is a PEG-10 linear dimethicone surfactant.

6. The antimicrobial composition of claim 1, wherein the composition is free of an additional surfactant.

7. The antimicrobial composition of claim 1, further comprising from about 0.005 to about 5 wt. % of a terpenoid.

8. The antimicrobial composition of claim 4, wherein said skin conditioner is selected from the group consisting of ethylhexylglycerin, hydroxyethylurea, urea, panthenol, glycerin, isopropyl myristate, propylene glycol, tocopheryl acetate, polyquaternium-11 and mixtures thereof.

18. The antimicrobial composition of claim 1, further comprising from about 0.005 to about 5 wt. % of a terpenoid.

9. An alcohol containing antimicrobial foaming composition comprising a PEG-8 to PEG-12 linear silicone surfactant foaming agent having an average foam height of greater than 20 mm;

and further having less than about 5 wt. % additional surfactant.

10. The antimicrobial composition of claim 9, wherein said composition is a liquid emulsion.

11. The antimicrobial composition of claim 9, wherein said composition is a ready to use composition.

12. The antimicrobial composition of claim 9, wherein said composition is a structured liquid composition.

13. The antimicrobial composition of claim 9, wherein said composition is a water thin liquid composition.

14. A foaming antimicrobial composition comprising:

a) from about 0.5 to 1 grams of foaming agent surfactant having an average foam height of greater than 20 mm;

b) from about 50 to about 90 wt. % of at a C₂ to C₄ alcohol;

c) water;

wherein there is less than about 5 wt. % of an additional surfactant.

15. The antimicrobial composition of claim 14, further comprising from about 0.01 to about 20 wt. % of a skin conditioner.

16. The antimicrobial composition of claim 14, wherein the foam agent is a PEG-8 to PEG-12 linear dimethicone surfactant.

17. The antimicrobial composition of claim 14, wherein the composition is free of an additional surfactant.

19. The antimicrobial composition of claim 15, wherein said skin conditioner is selected from the group consisting of ethylhexylglycerin, hydroxyethylurea, urea, panthenol, glycerin, isopropyl myristate, propylene glycol, tocopheryl acetate, polyquatemium-11 and mixtures thereof.

20. A foaming antimicrobial composition comprising:

a) from about 0.5 to about 1 gram of foaming agent surfactant having an average foam height of greater than 20 mm;

b) from about 50 to about 90 wt. % of at a lower chain alcohol;

c) water;

wherein there is less than about 5 wt. % of an additional surfactant.

21. The composition of claim 20 wherein said alcohol is a C₂ to C₄ alcohol.

22. The composition of claim 20 wherein said alcohol is in an amount of from about 50 to about 90 wt. % of said composition.

23. The antimicrobial composition of claim 20, further comprising from about 0.01 to about 20 wt. % of a skin conditioner.

24. The antimicrobial composition of claim 20, wherein the foam agent is a PEG-8 to PEG-12 linear dimethicone surfactant.

25. The antimicrobial composition of claim 20, wherein the composition is free of an additional surfactant.

26. The antimicrobial composition of claim 20, further comprising from about 0.005 to about 5 wt. % of a terpenoid.

27. The antimicrobial composition of claim 23, wherein said skin conditioner is selected from the group consisting of ethylhexylglycerin, hydroxyethylurea, urea, panthenol, glycerin, isopropyl myristate, propylene glycol, tocopheryl acetate, polyquatemium-11 and mixtures thereof.

28. A method of for reducing microorganisms on a target surface comprising:

applying to said target surface a non-aerosol foaming antimicrobial composition comprising;

a) a foaming agent comprising a PEG-8 to PEG-12 linear dimethicone surfactant having an average foam height of greater than 20 mm;

b) an alcohol; and

c) water

wherein there is less than about 5 wt. % of an additional surfactant.

29. The method of claim 28 wherein said surface is a skin surface.

30. The method of claim 28 wherein said skin surface is a facial skin surface.

31. The method of claim 28 wherein said skin surface is a hand skin surface.
