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 linear dimethicone surfactant;

b) a C₂ to C₄ alcohol; and

c) water.

2. The composition of claim 1 wherein said C₂ to C₄ alcohol is in an amount of from about 50 wt. % to about 90 wt. % of said composition.

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

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

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

6. 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.

7. A non-aerosol foaming antimicrobial composition comprising:

a) a foaming agent comprising a PEG-10 linear dimethicone surfactant;

b) a C₂ to C₄ alcohol; and

C) water.

8. The composition of claim 7 wherein said C₂ to C₄ alcohol is in an amount of from about 50 wt. % to about 90 wt. % of said composition.

9. The antimicrobial composition of claim 7, further comprising from about 0.01 to about 20 wt. % of a skin conditioner.

10. The antimicrobial composition of claim 7, wherein the composition is free of an additional surfactant.

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

12. The antimicrobial composition of claim 11, 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.

13. An alcohol containing antimicrobial foaming composition comprising a PEG-8 or PEG-10 linear silicone surfactant foaming agent.

14. The antimicrobial composition of claim 13, wherein said composition is a liquid emulsion.

15. The antimicrobial composition of claim 13, wherein said composition is a ready to use composition.

16. The antimicrobial composition of claim 13, wherein said composition is a structured liquid composition.

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