CDC Guidelines on Hypochlorous Acid HOCl

From the CDC

Chlorine and Chlorine Compounds
Overview.

Hypochlorites, the most widely used of the chlorine disinfectants, are available as liquid (e.g., sodium hypochlorite) or solid (e.g., calcium hypochlorite). The most prevalent chlorine products in the United States are aqueous solutions of 5.25%–6.15% sodium hypochlorite (see glossary), usually called household bleach. They have a broad spectrum of antimicrobial activity, do not leave toxic residues, are unaffected by water hardness, are inexpensive and fast acting 328, remove dried or fixed organisms and biofilms from surfaces465, and have a low incidence of serious toxicity 515-517. Sodium hypochlorite at the concentration used in household bleach (5.25-6.15%) can produce ocular irritation or oropharyngeal, esophageal, and gastric burns 318, 518-522. Other disadvantages of hypochlorites include corrosiveness to metals in high concentrations (>500 ppm), inactivation by organic matter, discoloring or “bleaching” of fabrics, release of toxic chlorine gas when mixed with ammonia or acid (e.g., household cleaning agents) 523-525, and relative stability 327. The microbicidal activity of chlorine is attributed largely to undissociated hypochlorous acid (HOCl). The dissociation of HOCI to the less microbicidal form (hypochlorite ion OCl‑) depends on pH. The disinfecting efficacy of chlorine decreases with an increase in pH that parallels the conversion of undissociated HOCI to OCl‑ 329, 526. A potential hazard is production of the carcinogen bis(chloromethyl) ether when hypochlorite solutions contact formaldehyde 527 and the production of the animal carcinogen trihalomethane when hot water is hyperchlorinated 528. After reviewing environmental fate and ecologic data, EPA has determined the currently registered uses of hypochlorites will not result in unreasonable adverse effects to the environment 529.

Hypochlorous Acid: The IDEAL Sanitizer and Disinfectant

Hypochlorous Acid (HOCl) is becoming on of the best solutions to fight against COVID and other diseases. According to the US National Library of Medicine, Hypochlorous Acid is an excellent choice for a wide range of applications. From cleaning air, to mouthwash, and a general cleaner, HOCl is rapidly becoming the choice of medical professionals. From the website: “a disinfectant agent changes the protective protein coat, which loses its structure and aggregates, forming clumps of proteins with other viruses. Currently, the US Environmental Protection Agency has recommended numerous disinfectants against COVID-19 including hypochlorous acid (HOCl).”

The main, traditional drawback to HOCl is stability and shelf life. Typically, the shelf life expected is 18-24 months. Since we produce HOCl in-house, we have the ability to deliver the best quality HOCl, quickly.

Can Air Conditioning Spread the Coronavirus? Why Experts Are Concerned About Public Spaces

Federal officials are exploring the role of the upcoming summer season on the spread of the novel coronavirus in the United States, debating experts’ arguments that humidity, temperatures, and direct sunshine won’t have a direct impact on the virality of COVID-19. But a new piece of evidence published in the journal Emerging Infectious Diseases, shared by the Centers for Disease Control and Prevention, suggests that a more pressing concern might be the role that air conditioners will play in keeping communities safe throughout the warmer months.

The newly published study found that nine people were infected with COVID-19 simply by sitting near an air-conditioning vent in a restaurant in Wuhan, China, where the coronavirus was first identified. The study examined how one asymptomatic diner managed to impact diners around their vicinity as infectious droplets were circulated by the air conditioning system. The person in question sat at a table that was located in front of an AC unit. Four people at the person’s table later tested positive for COVID-19, as well as five people at neighboring tables.
