Abstract

A foaming antimicrobial composition, which includes a cationic antimicrobial, a combination of surfactants, skin conditioning agent(s), humectant(s), and water, is provided. The composition has excellent antimicrobial properties, while still maintaining skin hydration and mildness. Commonly, the foaming antimicrobial composition is triclosan-free.

Claims (19)

1. An aqueous antimicrobial composition comprising

a. about 0.3 to 1.0 wt. % benzalkonium antimicrobial;

b. about 0.5 to 3 wt. % of a tertiary amine oxide surfactant, which comprises lauryl amine oxide, soyamidopropyl amine oxide, and cocamidopropyl amine oxide;

c. about 0.5 to 2 wt. % of a PEG-based nonionic surfactant;

d. about 0.1 to 2 wt. % of a C 10 -C 12 alkyl glycoside nonionic surfactant;

e. about 0.05 to 0.3 wt. % of a quaternary ammonium phospholipid zwitterionic surfactant comprising cocamidopropyl dimonium chloride phosphate;

f. about 0.1 to 0.3 wt. % of a C 10 -C 16 fatty acid isopropanolamide;

g. about 0.5 to 2 wt. % of a water-soluble silicone polymer;

h. about 0.1 to 2 wt. % of a cellulose derivative comprising cetyl cellulose and/or hydroxypropyl methylcellulose;

i. about 0.05 to 0.3 wt. % of a cationic acrylamide-based polymer;

j. about 0.1 to 2 wt. % of a humectant comprising hexylene glycol, glycerin, and/or sorbitol; and

at least about 85 wt % water;

wherein the combined amounts of the tertiary amine oxide surfactant, the isopropanolamide, the zwitterionic surfactant and the nonionic surfactants constitute no more than about 1.7 wt. % of the composition; and the composition has a pH of about 6 to 7.

2. The antimicrobial composition of claim 1 , wherein the C 10 -C 16 fatty acid isopropanolamide comprises cocamide monoisopropanolamide.

3. The antimicrobial composition of claim 1 , wherein the water-soluble silicone polymer comprises polyethyleneglycol dimethicone.

4. The antimicrobial composition of claim 1 , wherein the alkyl glycoside nonionic surfactant comprises decyl glucoside and/or lauryl glucoside.

5. The antimicrobial composition of claim 1 , wherein the composition further comprises one or more of the following: after-feel component, additional antimicrobial, solvent, viscosity modifying agent, preservative, perfume, dye, and buffer.

6. The antimicrobial composition of claim 1 , wherein the PEG-based nonionic surfactant comprises polyethyleneglycol fatty acid diester.

7. The aqueous antimicrobial composition of claim 1 , wherein the C 10 -C 16 fatty acid isopropanolamide comprises cocamide monoisopropanolamide; the water-soluble silicone polymer comprises polyethyleneglycol dimethicone; the C 10 -C 12 alkyl glycoside nonionic surfactant comprises decyl glucoside and/or lauryl glucoside; and the PEG-based nonionic surfactant comprises polyethyleneglycol sorbitan fatty acid ester and/or polyethyleneglycol fatty acid diester.
