Benefits of HOCl

Stabilized Hypochlorous acid (HOCl) helps reduce itch, inflammation and pain. It is also a powerful antimicrobial that kills skin pathogens associated with atopic dermatitis.1-4

What are the Key Clinical Benefits of HOCl?

  • Potent antimicrobial1
  • Reduction of pain and itch2,3
  • Reduction of inflammation4
  • Increased oxygenation of wound site5
  • Breaks down biofilm formed by S. aureus6
  • Helps with wound healing6

Reduction in Pain and Itch

Study 1: Open-Label Study2

Study Design

  • Open-label, single-arm study over 7 days


  • HOCl rapidly reduces pruritus in mild-to- moderate atopic dermatitis (AD)
    • 50% of patients experienced a reduction by Day 1
    • 85% of patients experienced a reduction by Day 3

Study 2: Randomized, Blinded, Controlled Study3

Study Design

  • 72-hour study
  • Treated group (n=19): HOCl BID
  • Untreated group (n=10): No treatment


  • Mean pruritus VAS scores between treated and
    untreated group were significantly different between
    baseline and 72 hours post application

Anti-Inflammatory Activity4

HOCl for Inhibition of Mast Cell Degranulation

  • Prevents allergen and calcium-induced mast cell degranulation for up to 8 hours after a single exposure in vitro
  • Reduces wound inflammation that inhibits healing
  • Stabilizes the mast cell membrane to inhibit the cell machinery for granule secretion, while not altering the signal transduction pathways or calcium mobilization
  • Inhibits degranulation stimulated by antigen or calcium ionophore



*A23187 + PMA is a calcium ionophore; †b-hexosaminidase is a marker of IgE-antigen-induced mast cell degranulation.

Increases Oxygenation5

  • Provides higher levels of oxygen at a wound site after application
  • Elevated blood and oxygen flow increases wound-healing nutrients

Breaks Down Bacterial Biofilm6

Biofilm formation is recognized as a serious problem in chronic wound infections. Biofilm characteristics include:

  • Complex structure of microorganisms that generate a protective shell, allowing bacteria to collect and proliferate
  • Most microorganisms that form biofilms found growing in microbial infection
  • Adheres to chronic wounds, makes phagocytosis difficult, and increases resistance to antibiotics

HOCl has antibiofilm activity and actively breaks down biofilm and kills microorganisms within the biofilm.



  • Corresponding microbicidal activity: 1/64 and lower dilutions of HOCl demonstrated zero colony-forming units of S. aureus

Assists Wound Healing6

Wound healing involves a complex sequence of events. Fibroblasts are the primary synthetic cells in the repair process of most structural proteins used during tissue reconstruction.

At lower concentrations, the percentage of fibroblast migration exceeded that of the control at 24 hours.

Effect of HOCl on Skin Fibroblast Cell Migration in a Wound Healing Assay



Although fibroblasts have a critical role in wound healing, their proliferation highly relates to keratinocyte proliferation and mediators secreted from keratinocytes.

  • Similar results were obtained for keratinocyte migration: At lower HOCl concentrations, the percentage of keratinocyte migration exceeded that of the control at 24 hours
