Abstract

Disinfecting compositions containing hypochlorous acid and acetic acid are useful for treating biofilms in or on tissue, including biofilms related to wounds or other skin trauma. The compositions are useful for treating a variety of types of tissue, both on the surface on beneath the surface of tissue. Compositions are provided having various concentrations for different tissue types and infection levels. Compositions may be provided in gel form, and may include nanoparticle encapsulated molecules for controlled release.

Claims (11)

1. A method for treating tissue trauma, the method comprising:

administering a composition to a tissue subject to a trauma, the composition comprising an air-free solution of hypochlorous acid and acetic acid, the hypochlorous acid having a concentration of approximately 200 ppm and the acetic acid having a concentration of approximately 2.0 wt %.

2. The method of claim 1 , further comprising making a surgical incision in the tissue, wherein the tissue is within a surgical operating field.

3. The method of claim 2 , wherein the composition is administered to the tissue before making the surgical incision.

4. The method of claim 2 , wherein the composition is administered to the tissue after making the surgical incision.

5. The method of claim 1 , further comprising debriding the tissue with the composition.

6. The method of claim 1 , wherein the tissue comprises skin.

7. The method of claim 1 , wherein the composition is buffered and has a pH approximately equal to a pKa of acetic acid.

8. The method of claim 1 , wherein the composition comprises a liquid, powder, lotion, cream, gel, oil, ointment, gel, solid, semi-solid, or aerosol spray.

9. The method of claim 1 , wherein the administering step comprises spraying a mist onto the tissue, contacting the tissue with a wipe comprising the composition, contacting the tissue with a cream or lotion comprising the composition, soaking the tissue in the composition, submerging the tissue in the composition, or washing the tissue with the composition.

10. The method of claim 1 , wherein the concentration of hypochlorous further provides an analgesic effect to the surrounding tissue.
