Abstract

Foaming formulations including a quaternary ammonium compound and a foam stabilizer are disclosed. These foaming formulations are useful as leave-on liquid hand and surface sanitizers. The foaming formulations provide improved aesthetic properties and foaming appearance, while maintaining high antimicrobial capacity.

Claims

1. A foaming formulation comprising no less than 95 wt % water, a quaternary ammonium compound, and a foam stabilizer, wherein the foaming formulation is substantially free of C₁-C₆ alcohols.

2. The foaming formulation of claim 1 wherein the quaternary ammonium compound is selected from the group consisting of benzalkonium chloride, stearalkonium chloride, benzethonium chloride, and combinations thereof.

3. The foaming formulation of claim 1 wherein the quaternary ammonium compound is present in an amount of from about 0.08 wt % to about 0.25 wt %.

4. The foaming formulation of claim 3 wherein the quaternary ammonium compound is present in an amount of from about 0.10 wt % to about 0.15 wt %.

5. The foaming formulation of claim 1 wherein the foam stabilizer is selected from the group consisting of polyethylene oxide, cationic guar gum, cationic cellulose, polyquaternium-2, polyquaternium-4, polyquaternium-6, polyquaternium-7, polyquaternium-10, polyquaternium-11, polyquaternium-15, polyquaternium-16, polyquaternium-22, polyquaternium-42, and combinations thereof.

6. The foaming formulation of claim 1 wherein the foam stabilizer is present in an amount of from about 0.01 wt % to about 1.00 wt %.

7. The foaming formulation of claim 1 further comprising a preservative.

8. The foaming formulation of claim 1 further comprising a foam builder.

9. The foaming formulation of claim 8 wherein the foam builder is selected from the group consisting of cocamidopropyl PG-dimonium chloride phosphate, lauramidopropyl PG-dimonium chloride, meadowfoamamidopropyl PG-dimonium chloride, myristamidopropyl PG-dimonium chloride phosphate, palmitamidopropyltrimonium chloride, sodium cocoamphoacetate, disodium cocoamphodiacetate, and combinations thereof.

10. The foaming formulation of claim 1 further comprising a pH modifier.

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

12. The foaming formulation of claim 1 having at least a 4 log reduction of S. aureus ATCC 6538, E. coli ATCC 11229, S. aureus ATCC 33591, B. cepacia ATCC 35416, P. aeruginosa ATCC 15442, and C. albicans ATCC 10231 within 15 seconds after contact.

13. The foaming formulation of claim 1 comprising at least 98 wt % water.

14. A foaming formulation comprising no less than 95 wt % water, benzalkonium chloride, and a foam stabilizer, wherein the foaming formulation is substantially free of C₁-C₆ alcohols.

15. The foaming formulation of claim 14 wherein the benzalkonium chloride is present in an amount of from about 0.08 wt % to about 0.25 wt %.

16. The foaming formulation of claim 14 wherein the foam stabilizer is selected from the group consisting of polyethylene oxide, cationic guar gum, cationic cellulose, polyquaternium-2, polyquaternium-4, polyquaternium-6, polyquaternium-7, polyquaternium-10, polyquaternium-11, polyquaternium-15, polyquaternium-16, polyquaternium-22, polyquaternium-42, and combinations thereof.

17. The foaming formulation of claim 14 wherein the foam stabilizer is present in an amount of from about 0.01 wt % to about 1.00 wt %.

18. A cleaning product comprising a dispenser and a foaming formulation, the foaming formulation comprising no less than 95 wt % water, a quaternary ammonium compound, and a foam stabilizer, wherein the foaming formulation is substantially free of C₁-C₆ alcohols.

19. The cleansing product of claim 18 wherein the dispenser is selected from the group consisting of non-aerosol pump, aerosol spray, and bottle.

20. The cleansing product of claim 18 wherein the quaternary ammonium compound is selected from the group consisting of benzalkonium chloride, stearalkonium chloride, benzethonium chloride, and combinations thereof.
