A method for sterilizing an aqueous antiseptic solution, the method comprising providing a container containing the aqueous antiseptic solution, the aqueous antiseptic solution comprising a bis-(dihydropyridinyl)-decane derivative or a biguanide, heating the aqueous antiseptic solution to a predeter
A method for sterilizing an aqueous antiseptic solution, the method comprising providing a container containing the aqueous antiseptic solution, the aqueous antiseptic solution comprising a bis-(dihydropyridinyl)-decane derivative or a biguanide, heating the aqueous antiseptic solution to a predetermined temperature, maintaining the aqueous antiseptic solution at the predetermined temperature for a predetermined time, and terminating the heating of the aqueous antiseptic solution when the predetermined time expires. The predetermined temperature and the predetermined time are selected such that after terminating the heating, the aqueous antiseptic solution is sterile.

1. A method for sterilizing an aqueous antiseptic solution, the method comprising: providing a container containing the aqueous antiseptic solution, the aqueous antiseptic solution comprising about 2.0% w/v chlorhexidine gluconate;heating the aqueous antiseptic solution to a predetermined temperature, wherein the predetermined temperature is from about 100° C. to about 140° C.;maintaining the aqueous antiseptic solution at the predetermined temperature for a predetermined time; andterminating the heating of the aqueous antiseptic solution when the predetermined time expires,wherein the predetermined temperature and the predetermined time are selected such that after terminating the heating, the aqueous antiseptic solution is sterile. 2. The method of claim 1, wherein prior to heating, the aqueous antiseptic solution has an initial purity,wherein after terminating the heating, the aqueous antiseptic solution has a post-sterilization purity, andwherein the predetermined temperature and the predetermined time are selected such that the post-sterilization purity is at least about 90% and a percentage point change in purity from the initial purity to the post-sterilization purity of at most about 8%. 3. The method of claim 2, where the post-sterilization purity is at least about 93% and a percentage point change in purity from the initial purity to the post-sterilization purity of at most about 5%. 4. The method of claim 2, where the post-sterilization purity is at least about 95% and a percentage point change in purity from the initial purity to the post-sterilization purity of at most about 3%. 5. The method of claim 1, wherein the predetermined temperature is from about 110° C. to about 130° C. 6. The method of claim 1, wherein the predetermined temperature is from about 115° C. to about 125° C. 7. The method of claim 1, wherein the predetermined time is from about 20 minutes to about 33 hours. 8. The method of claim 1, wherein the predetermined time is from about 6 minutes to about 11 hours. 9. The method of claim 1, wherein the predetermined time is from about 1 minute to about 2 hours. 10. The method of claim 1, wherein the aqueous antiseptic solution comprises at least 50% v/v water. 11. The method of claim 1, wherein the aqueous antiseptic solution comprises at least 90% v/v water. 12. The method of claim 1, wherein after terminating the heating, the aqueous antiseptic solution is completely free of microbes. 13. The method of claim 1, wherein the aqueous antiseptic solution comprises from about 50% to about 100% v/v water. 14. The method of claim 1, wherein the aqueous antiseptic solution comprises about 100% v/v water. 15. The method of claim 1, wherein the aqueous antiseptic solution consists essentially of: chlorhexidine gluconatefrom about 50% to about 100% v/v water. 16. The method of claim 1, wherein the aqueous antiseptic solution consists essentially of: from about 65% to about 100% v/v water;chlorhexidine gluconate. 17. The method of claim 1, wherein the aqueous antiseptic solution consists essentially of: about 100% v/v water;chlorhexidine gluconate. 18. The method of claim 1, wherein the aqueous antiseptic solution consists of: about 75% to about 100% v/v water;chlorhexidine gluconate; andthe remainder volume alcohol. 19. The method of claim 1, wherein the aqueous antiseptic solution comprises a non-active ingredient. 20. The method of claim 19, wherein the non-active ingredient is selected from the group consisting of a moisturizing agent, skin smoothing agent, a visualization agent, a solubility agent, a stability agent, a viscosity agent, and a wetting agent. 21. A sterile aqueous antiseptic solution prepared according to the method of claim 1.
