Research Regarding HOCL (hypochlorous acid)

Quick Summaries

Some General Information About HOCL

It Is Made By The Body

• ^UPH1Hypochlorous acid (HOCl) is a naturally occurring oxidant that is produced by white blood cells within the human body; it acts as the main ingredient used by our immune systems (phagocytesA cell that can incorporate and store or break down solid particles (bacteria, other cells, foreign material, etc.); esp. a neutrophil or macrophage ^OED1) to destroy disease-forming pathogens. Due to the antimicrobial properties and safety aspects of HOCl it can be adapted to almost any industry in solving challenges.
• Characteristics:

   Epub 2014 Nov 24. Evaluation of sprayed hypochlorous acid solutions for their virucidal activity against avian influenza virus through in vitro experiments

   • Hypochlorous acid (HOCl) solutions were evaluated for their virucidal ability against a low pathogenic avian influenza virus (AIVInfluenza A viruses have different subtypes and different lineages. Wild aquatic birds, are considered reservoirs (hosts) for avian influenza A viruses. ^CDC1), H7N1A subtype of the Avian Influenza Type A Viruses ^NIH1.
   • Under plain diluent conditions (without FBSFetal Bovine Serum used as a 5% solution during this study. ^TFS1), harvested solutions of HOCl after spraying could decrease the AIV titerThe strength of a solution or the concentration of a substance in solution as determined by titration ^MWD1 by more than 1,000 times, to an undetectable level (< 2.5 log10TCID50/ml) within 5 sec.
   • When HOCl solutions were sprayed directly on the virus on rayon sheets for 10 sec, the solutions of 100 and 200 ppm could inactivate AIV immediately after spraying
   • In the indirect spray form, after 10 sec of spraying, the lids of the dishes were opened to expose the virus on rayon sheets to HOCl. In this form, the 200 ppm solution inactivated AIV within 10 min of contact, while 50 and 100 ppm could not inactivate it.
   • These data suggest that HOCl can be used in spray form to inactivate AIV at the farm level.

   JPub 2022 Sep 14. Hypochlorous Acid Chemistry in Mammalian Cells—Influence on Infection and Role in Various Pathologies

   • This review discusses the formation of hypochlorous acid HOCl and the role of reactive chlorinated species (RCS)Reactive chlorine species (RCS) are powerful oxidants that are important for public health and disinfection:.^JBC1, which are catalysed by the enzyme myeloperoxidase MPO, mainly located in leukocytes and which in turn contribute to cellular oxidative stress.
   • The reactions of RCS with various organic molecules such as amines, amino acids, proteins, lipids, carbohydrates, nucleic acids, and DNA are described, and an attempt is made to explain the chemical mechanisms of the formation of the various chlorinated derivatives and the data available so far on the effects of MPO, RCS and halogenative stress.
   • Among the most widespread reactive agents are reactive oxygen species (ROS), such as superoxide anion, hydrogen peroxide and hydroxyl radical, as well as reactive chlorine species (RCS), such as hypochlorous acid ^PMC1

   Biotechnol Bioeng . 2022 Oct 7 Activity of a hypochlorous acid‐producing electrochemical bandage as assessed with a porcine explant biofilm model

   • Hypochlorous acid‐producing electrochemical bandage (e‐bandage) in preventing methicillin‐resistant Staphylococcus aureus infection (MRSA) infection
   • HOCl concentrations in infected and uninfected explant tissue varied between 30 and 80 µM, decreasing with increasing distance from the e‐bandage
   • Eukaryotic cell viability was reduced by an average of 71% and 65% in fresh and day 3‐old explants, respectively, when compared to explants exposed to nonpolarized e‐bandages
   • An estimated 2% of the United States population struggles with chronic wounds, a significant burden for affected patients and an over $50 billion per year cost to the healthcare system
   • The presence of pathogenic biofilms in the wound‐beds hinders the normal process of wound recovery
   • Biofilms are aggregates of microorganisms that express extracellular polymeric substance (EPS) which acts as a protective barrier against hazards to the cells within
   • Microorganisms within biofilms alter the wound bed environment by secreting toxins and/or enzymes, creating alkaline conditions, or reducing oxygen concentration in the wound bed
   • Hypochlorous acid (HOCl), a common biocide, is active against MRSA

   2019 Nov. 20; Wonder Spray (HOCL) Kills the Bacteria that Cause Strep Throat and Pneumonia

   • The bacteria that is the cause of strep throat is Streptococcus pyogenes and one cause of pneumonia is infection with Streptococcus pneumoniae.
   • Wonder sprayI was unable to determine the concentration used in testing. There are, as of Dec. 08, 2024, two concertrations of Dr. Burd's product; 180 ppm, and 0.02% (which is 200 ppm) is a new product with an active ingredient of Hypochlorous acid (HOCL) that has been FDA cleared for use in wound healing.
   • We performed a kill time study to determine if HOCL was effective in killing Streptococcus pyogenes and Streptococcus pneumoniae. We discovered that HOCL kills these bacteria with a 6-log reductionA 6-log reduction is a 99.9999% reduction. in less than 15 seconds.

   Epub 2020 Jan 6. Topical stabilized hypochlorous acid: The future gold standard for wound care and scar management in dermatologic and plastic surgery procedures

   • HOCl is active against biofilm and increases oxygenation of the wound site to improve healing. Natural HOCl is unstable; through technology, it can be stabilized into an effective topical antiseptic agent.
   • This paper focuses on the use of topical stabilized HOCl in wound and scar management for pre-, peri-, and postprocedures-including its ability to reduce the occurrence hypertrophic scars and keloids.
   • For wound care and scar management, topical stabilized HOCl conveys powerful microbicidal and antibiofilm properties, in addition to potency as a topical wound healing agent. It may offer physicians an alternative to other less desirable wound care measures.

   2023 Nov 30; Candida albicans resistance to hypochlorous acid

   • Innate immune cells, especially neutrophils, play key roles in protecting against infection by Candida albicans and other fungal pathogens.
   • A distinct aspect of neutrophils compared to other phagocytes is that they make much higher levels of myeloperoxidase, which converts H2O2 generated during the oxidative burst into highly reactive hypochlorous acid (HOCl).
   • Hypochlorous acid (HOCl), commonly known as bleach, is generated during the respiratory burst by phagocytes and is a key weapon used to attack Candida albicans and other microbial pathogens.
   • HOCl kills C. albicans more effectively than H2O2 and results in disruption of the plasma membrane.
   • myeloperoxidase deficiency is associated with a greater risk of infection by C. albicans in patients with other underlying diseases such as diabetes

    2024 May 29;The HOCl dry fog–is it safe for human cells?

    • This study aims to investigate if high-concentration HOCl fogging disinfection causes cytotoxicity and genotoxicity to cultured primary human skin fibroblasts.
    • The cells were exposed to a dry fog of HOCl produced from solutions with a concentration of 300 ppm (5.72 mM) or 500 ppm (9.53 mM).
    • After four times when fibroblasts were exposed to aerosolized HOCl at a concentration of 500 ppm for 9 minutes, significant cytotoxicity and genotoxicity effects were observed.
    • No analogous damages were found when the cells were exposed to aerosolized HOCl generated from a 300-ppm solution for 3 minutes, whether once or four times.
    • We have concluded that aerosolized HOCl in dry fog, with a concentration exceeding 300 ppm, can cause cytotoxic and genotoxic effects on human skin fibroblasts.
