Abstract

Foaming formulations including silicone polyesters are disclosed. These foaming formulations are useful as cleansing formulations such as used in hand sanitizers. The foaming formulations provide improved aesthetic properties and foaming appearance, while maintaining high antimicrobial capacity.

Claims

1. A foaming formulation comprising water, an alcohol, and a silicone polyester, wherein the silicone polyester comprises the following structure:

2. The foaming formulation of claim 1 comprising from about 5.0% by weight to about 45% by weight water, from 50% by weight to about 90% by weight alcohol, and from about 0.1% by weight to about 10% by weight silicone polyester.

3. The foaming formulation of claim 1 comprising from about 10% by weight to about 40% by weight water.

4. The foaming formulation of claim 1 comprising from about 20% by weight to about 30% by weight water.

5. The foaming formulation of claim 1, wherein the alcohol is selected from the group consisting of methanol, ethanol, n-propanol, isopropanol, n-butanol, tert-butanol, 2-butanol, pentanol, hexanol, and combinations thereof.

6. The foaming formulation of claim 1 comprising from about 60% by weight to about 80% by weight alcohol.

7. The foaming formulation of claim 1 comprising from about 65% by weight to about 75% by weight alcohol.

8. The foaming formulation of claim 1 comprising from about 0.25% by weight to about 5% by weight silicone polyester.

9. The foaming formulation of claim 1 comprising from about 0.5% by weight to about 4% by weight silicone polyester.

10. The foaming formulation of claim 1 further comprising at least one agent selected from the group consisting of emollients, humectants, moisturizers, botanicals, foam stabilizers, vitamins, disinfectants, non-aqueous solvents, preservatives, pH modifiers, sequestrants, antimicrobials, antioxidants, anti-reddening agents, astringents, deodorants, external analgesics, film formers, fragrances, hydrotropes, opacifiers, skin conditioning agents, skin exfoliating agents, skin protectants, sunscreens, and thickeners.

11. A process of preparing a foaming formulation, the process comprising mixing water, an alcohol, and a silicone polyester, wherein the silicone polyester comprises the following structure:

12. The process of claim 11, wherein from about 5% by weight to about 45% by weight of water, from 50% by weight to about 90% by weight of the alcohol, and from about 0.1% by weight to about 10% by weight of the silicone polyester are mixed.

13. The process of claim 11, wherein from about 10% by weight to about 40% by weight of water, from about 60% by weight to about 80% by weight of the alcohol, and from about 0.25% by weight to about 5% by weight of the silicone polyester are mixed.

14. The process of claim 11, wherein from about 20% by weight to about 30% by weight of water, from about 65% by weight to about 75% by weight of the alcohol, and from about 0.5% by weight to about 4% by weight of the silicone polyester are mixed.

15. The process of claim 11, wherein the alcohol is selected from the group consisting of methanol, ethanol, n-propanol, isopropanol, n-butanol, tert-butanol, 2-butanol, pentanol, hexanol, and combinations thereof.

16. A method for bodily cleansing comprising topically applying to skin a foaming formulation comprising water, an alcohol, and a silicone polyester, wherein the silicone polyester comprises the following structure:

17. The method of claim 16, wherein the foaming formulation comprises from about 5.0% by weight to about 45% by weight water, from 50% by weight to about 90% by weight alcohol, and from about 0.1% by weight to about 10% by weight silicone polyester.

18. The method of claim 16, wherein the alcohol is selected from the group consisting of methanol, ethanol, n-propanol, isopropanol, n-butanol, tert-butanol, 2-butanol, pentanol, hexanol, and combinations thereof.

19. The method of claim 16, wherein the foaming formulation comprises from about 0.25% by weight to about 5% by weight silicone polyester.

20. The method of claim 16, wherein the foaming formulation comprises from about 0.5% by weight to about 4% by weight silicone polyester.
