Abstract

Disclosed herein are compositions and methods to treat microbial infections and heal wounds. In some embodiments, the microbial infection may be a microbial biofilm. In some embodiments, the composition of the invention may include at least one surface active agent. The surface active agents may be anionic, cationic or non-ionic, or any combination thereof.

Claims (41)

1. A composition for treating a microbial infection consisting essentially of:

a poloxamer at a concentration ranging from about 45 to about 55% w/w, the poloxamer consisting essentially of poloxamer 127, poloxamer 188, poloxamer 237, poloxamer 335, poloxamer 407 and combinations thereof,

glycerin at a concentration ranging from about 1 to about 3% w/w,

a preservative at a concentration ranging from about 0.1 to about 2% w/w,

a pH adjuster, and

water.

2. The composition according to claim 1 , the preservative is phenoxyethanol.

3. The composition according to claim 2 , the pH adjuster having at least one of citric acid and sodium phosphate dibasic.

4. The composition according to claim 3 , the pH adjuster having citric acid and sodium phosphate dibasic.

5. The composition according to claim 2 , the poloxamer is poloxamer 188.

6. The composition according to claim 5 , the preservative is phenoxyethanol.

7. The composition according to claim 6 , the pH adjuster having at least one of citric acid and sodium phosphate dibasic.

8. The composition according to claim 7 , the pH adjuster having citric acid and sodium phosphate dibasic.

9. A composition for treating a microbial infection consisting essentially of:

a poloxamer at a concentration ranging from about 45 to about 55% w/w, the poloxamer consisting essentially of poloxamer 127, poloxamer 188, poloxamer 237, poloxamer 335, poloxamer 407 and combinations thereof,

a preservative at a concentration ranging from about 0.1 to about 2% w/w,

a pH adjuster, and

water.

10. The composition according to claim 9 , the preservative is phenoxyethanol.

11. The composition according to claim 9 , the pH adjuster having at least one of citric acid and sodium phosphate dibasic.

12. The composition according to claim 11 , the pH adjuster having citric acid and sodium phosphate dibasic.

13. The composition according to claim 9 , the poloxamer is poloxamer 188.

14. The composition according to claim 13 , the preservative is phenoxyethanol.

15. The composition according to claim 14 , the pH adjuster having at least one of citric acid and sodium phosphate dibasic.

16. The composition according to claim 15 , the pH adjuster having citric acid and sodium phosphate dibasic.

17. A composition for treating a microbial infection consisting essentially of:

a poloxamer at a concentration ranging from about 45 to about 55% w/w, the poloxamer consisting essentially of poloxamer 127, poloxamer 188, poloxamer 237, poloxamer 335, poloxamer 407 and combinations thereof,

glycerin at a concentration ranging from about 1 to about 3% w/w,

a preservative;

a pH adjuster;

a saccharide; and

water.

18. The composition according to claim 17 , the preservative is phenoxyethanol.

19. The composition according to claim 17 , the pH adjuster having at least one of citric acid and sodium phosphate dibasic.

20. The composition according to claim 19 , the pH adjuster having citric acid and sodium phosphate dibasic.

21. The composition according to claim 17 , the poloxamer is poloxamer 188.

22. The composition according to claim 21 , the preservative is phenoxyethanol.

23. The composition according to claim 22 , the pH adjuster having at least one of citric acid and sodium phosphate dibasic.

24. The composition according to claim 23 , the pH adjuster having citric acid and sodium phosphate dibasic.
