Compositions and methods for treating transient biofilms
Disinfecting compositions containing hypochlorous acid and acetic acid are useful for treating transient biofilms in or on tissue without harming the natural flora of the tissue. The compositions are useful for treating a variety of types of tissue. Compositions are useful for treating and preventing orally-associated biofilm. Compositions may be provided in mouthwash form, spray form, gel form, cream form, dentifrice form, and may include nanoparticle encapsulated molecules for controlled release.
1. An antimicrobial composition for treating and/or preventing pathogenic bacterial biofilms on a tissue surface without harming natural biofilm of the tissue, the composition comprising a mixture of acetic acid (HAc) and hypochlorous acid (HOCl) having concentrations optimized so as to achieve a synergistic effect resulting in the composition being capable of reducing the presence of transient bacteria on the tissue surface at a greater rate than the presence of natural bacteria on the tissue surface, the HAc having a concentration of 0.13 wt % and the HOCl having a concentration of 0.03 wt %.
2. The composition of claim 1 , wherein the tissue is skin tissue.
3. The composition of claim 2 , wherein the skin tissue is epidermal tissue.
4. The composition of claim 2 , where in the tissue is vaginal tissue.
5. The composition of claim 1 , wherein the composition is formulated in a spray, gel, cream, ointment, or oil.
6. The composition of claim 1 , wherein the acetic acid is encapsulated in a nanoparticle.
