Abstract

An antiseptic cleaning agent, generally, comprising chlorhexidine acetate and a solvent, such as an alcohol and/or water. The chlorhexidine acetate acts as a highly effective biocide. Additionally, the chlorhexidine acetate allows the cleaning agent to dry without leaving a tacky residue. Where the cleaning agent comprises one or more alcohols, the alcohols may comprise any suitable alcohols, including lower alcohols having from 1 to 6 carbon atoms, such as ethanol and isopropanol. Where the ratio of ethanol to isopropanol may be from between about 1:1000 to about 1000:1. In addition to chlorhexidine acetate, the cleaning agent optionally comprises another non-alcohol biocide, such as triclosan. The cleaning agent can be used in any suitable manner. For instance, the cleaning agent may be impregnated in an absorbent material, such as a towelette, swabstick, or gauze. Additionally, the absorbent material may comprise a positively charged or a non-ionic substance, such as polypropylene or polyester.

Claims (27)

1. An antiseptic cleaning agent for dermal use, comprising:

a first non-alcohol, biocidal agent comprising chlorhexidine acetate, wherein the chlorhexidine acetate comprises about 0.01% to about 10% of the cleaning agent, by weight; and

more than about 90% of the cleaning agent by weight of an alcohol comprising isopropanol and ethanol, wherein a ratio of the isopropanol to ethanol is from about 1:1000 to 1000:1, and wherein the cleaning agent does not leave a tacky residue when it dries.

2. The cleaning agent of claim 1 , wherein the ratio of the isopropanol to ethanol is from about 1:500 to 500:1.

3. The cleaning agent of claim 1 , wherein the ratio of the isopropanol to ethanol is from about 1:100 to 100:1.

4. The cleaning agent of claim 1 , wherein the ratio of the isopropanol to ethanol is from about 1:10 to 1:1.

5. The cleaning agent of claim 1 , further comprising water.

6. The cleaning agent of claim 1 , wherein the chlorhexidine acetate comprises about 0.5% to about 2% of the cleaning agent, by weight.

7. The cleaning agent of claim 1 , further comprising a second non-alcohol, biocidal agent that comprises from about 0.01% to about 10% of the cleaning agent, by weight.

8. An antiseptic cleaning agent for dermal use, comprising:

a first non-alcohol, biocidal agent comprising chlorhexidine acetate, wherein the chlorhexidine acetate comprises about 0.01% to about 10% of the cleaning agent, by weight; and

an alcohol comprising isopropanol and ethanol, wherein a ratio of the isopropanol to ethanol is from about 1:1000 to about 1000:1, wherein the cleaning agent does not leave a tacky residue when it dries.

9. The cleaning agent of claim 8 , wherein the ratio of isopropanol to ethanol is between about 500:1 and about 1:500.

10. The cleaning agent of claim 8 , wherein the ratio of isopropanol to ethanol is between about 100:1 and about 1:100.

11. The cleaning agent of claim 8 , wherein the ratio of isopropanol to ethanol is between about 10:1 and about 1:10.

12. An antiseptic cleaning agent for dermal use, comprising:

chlorhexidine acetate;

a solvent capable of dissolving the chlorhexidine acetate, wherein the solvent comprises isopropanol and ethanol and a ratio between the isopropanol and ethanol is from about 1:1000 to about 1000:1; and

an absorbent material, wherein the absorbent material is impregnated with the cleaning agent, and wherein the cleaning agent does not leave a tacky residue when it dries.

13. The cleaning agent of claim 12 , wherein the solvent comprises alcohol, which accounts for more than 90% of the cleaning agent, by weight.

14. The cleaning agent of claim 12 , wherein the solvent comprises water, which comprises more than about 90.1% of the cleaning agent, by weight.

15. An antiseptic cleaning agent consisting essentially of:

a first non-alcohol, biocidal agent comprising chlorhexidine acetate, wherein the chlorhexidine acetate comprises about 0.01% to about 10% of the cleaning agent, by weight; and

more than about 90% of the cleaning agent by weight of an alcohol comprising isopropanol and ethanol, wherein a ratio of the isopropanol to ethanol is from about 1:1000 to 1000:1, and wherein the cleaning agent does not leave a tacky residue when it dries.

16. The cleaning agent of claim 15 , wherein the chlorhexidine acetate comprises about 0.5% to about 2% of the cleaning agent, by weight.

17. The cleaning agent of claim 15 , further comprising a second non-alcohol, biocidal agent that comprises from about 0.01% to about 10% of the cleaning agent, by weight.

18. The cleaning agent of claim 15 , further comprising water.
