What is NeutroPhase, and how do I use it?

NeutroPhase is an FDA-cleared 510(k) skin and wound cleanser. For more information on how to use NeutroPhase, please read the Indications for Use.

What is the composition of NeutroPhase?

NeutroPhase is 0.03% pure hypochlorous acid in saline.


What is hypochlorous acid?

  • HOCl is produced daily by the body’s immune system in a complex series of events. Neutrophils release hypochlorous acid upon encountering pathogens, destroying those pathogens in the process.
  • HOCl does not create resistance and possesses rapid kill times.
  • Hypochlorous acid has been described as being 80-100 times more potent as a germicide than the hypochlorite anion (OCl; Dakin’s solution).
  • HOCl is effective against molds, fungi, yeasts, bacteria and viruses.

Why is NeutroPhase unique?

  • Only pure HOCl product available
  • Only HOCl product available with a 36 month shelf-life (others are 12 months or less indicating innate instability)
  • Only HOCl product made by a sophisticated compounding process (others made by electrolysis – “electrolyzed water”)
  • Pure, stable HOCl exists only in the narrow pH range that NeutroPhase occupies.
  • Patent covers the stable pH range for HOCl. Any other product manufactured with our process cannot be produced in this range.
  • Electrolysis products are not well pH controlled, leading to instability and short shelf life.
  • Packaged in medical-grade glass to prevent oxidation. Competitors’ products are packaged in PET plastics which begin to oxidize and destabilize immediately.
  • Unlike sodium hypochlorite anion (bleach) found in Dakins solution and other impure HOCl solutions, NeutroPhase is non-cytotoxic to granulating tissue.
  • No longer must clinicians face the unpleasant choice of either cleansing the wound of microorganisms or protecting fragile new tissue. Now both can be accomplished concurrently.
