Hypochlorous acid is being used in various innovative ways. 7m3. Evidence is emerging of the beneficial effects of inhaling microaerosolized hypochlorous acid (HOCl) as an intervention in the prevention and treatment of respiratory virus infections, Amid the sudden onset of the COVID-19 pandemic and early uncertainties about the mode of transmission, regulatory authorities globally were pressed to make recommendations about environmental disinfection measures. Additional data, including individual hematological, Ten Day Exposure to Hypochlorous Acid (Wonder Spray) Fog Results in no Detectable Effect on Blood Metabolic Panel and Minimal Lung Pathology Hypochlorous acid Lungs exposed to agents by inhalation (rather than particles or systemic) would be anticipated to have findings in the airways and alveoli. Natural hypochlorous acid is unstable; through technology, it can be stabilized into an effective topical antiseptic agent (Block 2020, Wang 2007). However, the generation of a potent oxidant is not without risk to the host, and there is evidence that HOCl contributes Abstract: During the disinfection of indoor spaces using gaseous hypochlorous acid （HOCl（g））, inhalation is the most common route of exposure for humans. Minimal Risk Levels (MRLs) Inhalation An MRL of 0. , NH 3). Hypochlorous acid-based antiseptic solutions are commercially available at different concentrations: the 0. [6] [7] The objective is to provide a comprehensive overview of the rapidly developing field of the current state of research on in vivo use of hypochlorous acid (HOCl) to aid infection prevention and control, including naso-pharyngeal, alveolar, topical, and systemic HOCl applications. Upon inhalation, bleach fumes can irritate the mucous membranes in the nose and throat. Similarly, hypochlorous acid is highly water soluble and has an injury pattern similar to hydrochloric acid, which may account for the toxicity of elemental chlorine and hydrochloric acid to the human body [13 Figure 1. In this study, an artificial human respiratory Hydration of chlorine gas (Cl 2) leads to formation of HCl and HOCl (hypochlorous acid). 1016 Hypochlorous Acid / Stabilised hypochlorous acid (HOCl) data were shown on the efficacy of these disinfectants in aerosolised form or potential health impacts related to inhalation or contact with the skin.
