Why is hocl an acid

Hypochlorous acid HOCl or hypo is not a new substance or chemistry. In fact, it has been around for decades — often used to clean wounds on the battlefield, to disinfect drinking water and as a surface disinfectant.

Historically, HOCl has also been commonly used in agriculture and dairy farming. For example, dairy farmers often use it as a teat dip, a post-milking technique that helps control the spread of mastitis organisms during the milking process.

Hypochlorous acid can also be found inside the human body. It naturally resides in white blood cells, helping the immune system keep people healthy. In recent years, HOCl has gained traction in the cleaning industry, too. Efficacy of neutral electrolyzed water for inactivation of human norovirus.

The current unavailability of an effective antiviral drug or approved vaccine means that the implementation of effective preventive measures is necessary to counteract COVID Oral-maxillofacial surgeons are high-risk providers providing needed care to patients. As more OMS and surgical offices open during reopening in the United States and elsewhere in the world, the need to reduce the risk of transmission of COVID between patients and providers is necessary.

It is widely believed that with proper screening and discretion, along with adequate personal protective equipment, there is a low probability of becoming infected. The goal of this article is to provide information regarding disinfection in the clinical office setting using HOCl, a relatively inexpensive, nontoxic, noncorrosive, and well-studied compound. HOCl has uses in many industries from farming and restaurants, regarding food, to health care applications, including chronic wound care and disinfection.

Additionally, the COVID virus can be present on some surfaces for days, and the disinfection of all surfaces of an operatory is important to reduce transmission. Although the shelf life of HOCl is relatively short, it is effective for up to 2 weeks under ideal conditions.

A gallon of HOCl can be purchased from manufacturers but it is far more economical for an oral-maxillofacial surgeon to produce the solution on-site in the office. These wipes may only last a day or two depending the size of the office and area to clean. Shortages of these products can occur, making sourcing them difficult as well. In addition to using HOCl in the form of wipes for disinfecting, using HOCl vapors through a fogging machine is an economical way to disinfect a large operating room or suite in which aerosols were produced during surgery.

Foggers or misting machines are handheld machines and can be purchased for a reasonable cost. It is important to note that the fogging process can alter the physical and chemical properties of the disinfectant, making it more dilute and basic.

The fine mist can be left in the empty surgical room without thought regarding harmful chemical effects; the surfaces are then wiped clean and dry after a few minutes and, for a more dilute solution, after 10 minutes. HOCl is one disinfectant that, when combined with adequate personal protective equipment, screening and social-distancing techniques, hand washing, and high-volume evacuation suction, may help reduce the transmission of COVID in the outpatient OMS setting.

It comprises many of the desired effects of the ideal disinfectant: It is easy to use, is inexpensive, has a good safety profile, and can be used to disinfect large areas quickly and with a broad range of bactericidal and virucidal effects.

Use of Disinfectants On contact with the virus, a disinfectant agent changes the protective protein coat, which loses its structure and aggregates, forming clumps of proteins with other viruses.

Hypochlorous Acid An ideal disinfectant and sanitizer must be nontoxic to surface contact, noncorrosive, effective in various forms, and relatively inexpensive. Stability of Solution Rossi-Fedele et al 35 investigated the shelf life of HOCl by being either exposed to or protected from sunlight. Concentration Related to Time Needed for Virucidal Action HOCl has been shown to inactivate a variety of viruses including coronaviruses in less than 1 minute.

Recommendations for Office Use Importance of Aerosol Size to Disinfection and Application Individuals working in the dental and medical field using surgical and high-speed handpieces are at risk from aerosolization.

Mouth Rinse If HOCl is used as a mouth rinse, one must assume that a portion of the rinse will be swallowed. Other Clinical Applications Ophthalmology HOCl is used in the treatment of blepharitis by reducing the bacterial load on the surface of the periocular skin. Biofilm HOCl may be effective for cleaning biofilm-contaminated implant surfaces. Wound Care In a clinical study on intraperitoneal wound care, patients underwent lavage of the peritoneal cavity with ppm HOCl and washing of the wound with ppm.
