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 handcare/skincare product comprising:

a) a foaming agent comprising a PEG-8 linear dimethicone surfactant;

b) a mixture of two or more C₂ to C₄ alcohols;

c) a skin conditioner; and

d) water;

wherein said product is a non-aerosol foaming antimicrobial product.

2. The handcare/skincare product 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 handcare/skincare product of claim 1, further comprising from about 0.01 to about 20 wt. % of a skin conditioner.

4. The handcare/skincare product of claim 1, wherein the composition is free of an additional surfactant.

5. The handcare/skincare product of claim 1, further comprising from about 0.005 to about 5 wt. % of a terpenoid.

6. The handcare/skincare product 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 handcare/skincare product comprising:

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

b) a mixture of two or more C₂ to C₄ alcohols;

c) a skin conditioner; and

c) water;

wherein said product is a non-aerosol foaming antimicrobial product.

8. The handcare/skincare product 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 handcare/skincare product of claim 7, further comprising from about 0.01 to about 20 wt. % of a skin conditioner.

10. The handcare/skincare product of claim 7, wherein the composition is free of an additional surfactant.

11. The handcare/skincare product of claim 7, further comprising from about 0.005 to about 5 wt. % of a terpenoid.

12. The handcare/skincare product 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. The handcare/skincare product of claim 11, wherein said composition is a ready to use composition.

14. The handcare/skincare product of claim 11, wherein said composition is a structured liquid composition.

15. The handcare/skincare product of claim 11, wherein said composition is a water thin liquid composition.

17. The method of claim 13 wherein said skin is hand skin.

18. The method of claim 13 wherein said skin is facial skin.

16. A method of reducing microorganisms on skin comprising:

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

a) a foaming agent comprising a PEG-8 and/or PEG-10 linear dimethicone surfactant;

b) a mixture of two or more C₂ to C₄ alcohols;

c) a skin conditioner; and

d) water.

19. The method of claim 16 wherein said composition further comprises a skin conditioning agent.

20. The method of claim 16 wherein said skin conditioning agent is selected from the group comprising:

ethylhexylglycerin, hydroxyethylurea, urea, panthenol, glycerin, isopropyl myristate, propylene glycol, tocopheryl acetate, polyquaternium-11 and mixtures thereof.
