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 for treating biofilms without inducing antimicrobial resistance.

Claims (10)

1 . A composition comprising:

an aqueous solution;

acetic acid (HAc) at an HAc concentration from about 2% to about 5% in the aqueous solution;

hypochlorous acid (HOCl) at an HOCl concentration from about 5 ppm to about 2500 ppm in the aqueous solution; and

a nanoparticle contained in the aqueous solution, wherein the acetic acid is encapsulated within the nanoparticle.

2 . The composition of claim 1 , wherein the HOCl concentration is approximately 25 ppm.

3 . The composition of claim 1 , wherein the HAc concentration is within the range of about 2% to about 4%, inclusive.

4 . The composition of claim 3 , wherein the HOCl concentration is within the range of about 200 ppm to about 500 ppm, inclusive.

5 . The composition of claim 1 , wherein the composition is formulated in a gel, cream, ointment, or oil.

6 . A method for treating a bacterial infection in tissue, the method comprising providing to the tissue the composition of any one of the preceding claims .
