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) from about 50 to about 90 wt. % of a C₂-C₄ alcohol; and

c) water

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

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

3. The antimicrobial composition of claim 2, wherein the 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.

4. The antimicrobial composition of claim 1, further comprising an additional ingredient selected from the group consisting of skin feel improvers, antioxidants, fragrances, dyes, and mixtures thereof.

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. A foaming antimicrobial composition comprising:

a) a foaming agent comprising a PEG-10 linear silicone surfactant having an average foam height of greater than 20 mm;

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

c) water

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

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

9. The antimicrobial composition of claim 7, further comprising an additional ingredient selected from the group consisting of skin feel improvers, antioxidants, fragrances, dyes, and mixtures thereof.

10. The antimicrobial composition of claim 7, wherein the composition is substantially free of a foam stabilizer.

11. The antimicrobial composition of claim 7, wherein the composition is substantially free of an additional silicone material.

12. The antimicrobial composition of claim 7, further comprising a skin conditioner selected from the group consisting of ethylhexylglycerin, hydroxyethylurea, urea, panthenol, glycerin, isopropyl myristate, propylene glycol, tocopheryl acetate, polyquaternium-11 and mixtures thereof.

13. A 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) from about 60 to about 80 wt. % of a C₂-C₄ alcohol;

c) from about 0. 1 to about 10 wt. % of a skin conditioner selected from the group consisting of glycerin, ethylhexyl glycerin, hydroxyethyl urea, urea, panthenol, and mixtures thereof, and

d) water.

14. The antimicrobial composition of claim 13, further comprising from about 0.005 to about 5 wt. % of a terpenoid.

15. The antimicrobial composition of claim 13, further comprising an additional ingredient selected from the group consisting of skin feel improvers, antioxidants, fragrances, dyes, and mixtures thereof.

16. The antimicrobial composition of claim 13, wherein the composition is substantially free of a foam stabilizer.

17. The antimicrobial composition of claim 13, wherein the composition is substantially free of an additional silicone material.

18. The antimicrobial composition of claim 13, wherein the foaming agent is PEG-10 linear dimethicone.

19. A foaming antimicrobial composition consisting essentially of:

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) from about 54 to about 85 wt. % of at least two C₂-C₄ alcohols;

c) from about 0.01 to about 20 wt. % of a chelating agent;

d) from about 0.01 to about 20 wt. % of a skin conditioner selected from the group consisting of glycerin, isopropyl myristate, propylene glycol, tocopheryl acetate, polyquaternium-11, and mixtures thereof;

f) from about 0 to about 3 wt. % of a paraben; and

g) water.

20. The antimicrobial composition of claim 19, further comprising an additional ingredient selected from the group consisting of skin feel improvers, antioxidants, fragrance, dye, and mixtures thereof.

21. The antimicrobial composition of claim 19, wherein the foam agent is a PEG-10 linear dimethicone surfactant.
