Abstract

Claims (32)

1. An antibacterial cleansing composition comprising:

a) from about 0.01% to about 1% of chloroxylenol by weight of the composition;

b) from about 5% to about 15% of sodium lauryl sulfate by weight of the composition;

c) from about 1% to about 5% of a co-surfactant by weight of the composition, wherein the co-surfactant is chosen from zwitterionic surfactant, amphoteric surfactant, nonionic surfactant, or mixtures thereof;

d) wherein the weight ratio of sodium lauryl sulfate to the co-surfactant ranges from about 3:1 to about 5:1; and

wherein the composition comprises a pH of from about 2 to about 5.

2. The antibacterial cleansing composition of claim 1 , comprising from about 0.10% to about 0.75% of chloroxylenol by weight of the composition.

3. The antibacterial cleansing composition of claim 2 , comprising from about 0.40% to about 0.60% of chloroxylenol by weight of the composition.

4. The antibacterial cleansing composition of claim 1 , comprising from about 0.005% to about 5% of pyrrolidone carboxylic acid by weight of the composition.

5. The antibacterial cleansing composition of claim 1 , wherein the composition comprises from about 7% to about 9% of sodium lauryl sulfate and wherein the antibacterial cleansing composition is a liquid hand wash composition.

6. The antibacterial cleansing composition of claim 1 , wherein the composition comprises from about 1.4% to about 3.0% of a co-surfactant by weight of the composition.

7. The antibacterial cleansing composition of claim 6 , wherein the co-surfactant comprises cocamidopropyl betaine.

8. The antibacterial cleansing composition of claim 7 , wherein the antibacterial cleansing composition has a weight ratio of sodium lauryl sulfate to cocamidopropyl betaine ranging from about 3:1 to about 5:1.

9. The antibacterial cleansing composition of claim 1 , wherein the pH is from about 3 to about 3.5.

10. The antibacterial cleansing composition of claim 1 , having a viscosity from about 2,750 cps to about 30,000 cps.

11. The antibacterial cleansing composition of claim 1 , wherein the viscosity is from about 5000 cps to about 10,000 cps.

12. A method of washing hands and washing away about 99% of bacteria comprising the following steps in that order:

a) providing a container adapted to contain the antibacterial cleansing composition of claim 1 ;

b) dispensing the antibacterial cleansing composition into palms of a user's hands;

c) lather by rubbing palms together;

d) spread the antibacterial cleansing composition across the palms, back of hands, between fingers, and/or under nails;

e) rinse hands;

f) dry;

g) wherein the antibacterial cleansing composition washes away about 99% of bacteria.

13. The method of claim 12 , wherein the container is a pump dispenser or a pump foam dispenser.

14. A liquid hand wash composition comprising:

a) from about 7% to about 9% of sodium lauryl sulfate by weight of the composition;

b) from about 1.75% to about 3% of cocamidopropyl betaine by weight of the composition;

c) wherein the weight ratio of sodium lauryl sulfate to cocamidopropyl betaine ranges from about 7.5:2.5 to about 8:2;

d) from about 0.40% to about 0.60% of chloroxylenol by weight of the composition; and

wherein the composition comprises a pH of from about 4 to about 5 and a viscosity of from about 3,000 cps to about 25,000 cps.

15. The liquid hand wash composition of claim 14 , wherein the liquid hand wash composition comprises about 8% sodium lauryl sulfate, about 2% cocamidopropyl betaine, and about 0.05% of chloroxylenol.
