The use of harmful alcohol-based disinfectants and sanitizers was a major concern throughout the CoVID-19 era. Frequent use of alcohol-based sanitizer can dry up the skin, and the effect is worsening for individuals with sensitive skin. Alcohol-based disinfectants are flammable and can ignite if used near a flame, spark, or other source of ignition. Using the electrolysis of sodium chloride (NaCl) aqueous solution method, this study aims to make Hypochlorous Acid (HOCl), a safe disinfectant and sanitizer. Two critical parameters were tested on the electrolysis effect of producing HOCl. The first is the amount of sodium chloride (NaCl) present, while the second is the type of electrode used, which are carbon, graphite, and titanium. The results showed that 10 grams of NaCl produces 50-200 ppm of HOCl, which is good for sanitizing purposes, and 30 grams of NaCl produces 500-800 ppm of HOCl, which is good for disinfecting purposes. The graphite electrode was also demonstrated to be capable of producing a clean HOCl solution. Using a UV-vis spectrophotometer, the effectiveness of the HOCl produced was determined, and it was discovered that HOCl is capable of killing bacteria. As a result, HOCl can be applied as a safe disinfectant and sanitizer in the fight against COVID-19. 1. Introduction More than a year has passed since the World Health Organization (WHO) declared coronavirus disease 2019 as a pandemic. The need for disinfectants and sanitizers has increased globally, particularly in the medical and health care sectors, as well as in other industries and for personal usage. Sanitizing reduces the numbers of germs, whereas disinfection eliminates germs by applying an EPA-registered microorganism-killing solution [1]. One of the most serious problems is the use of hazardous alcohol- based disinfectants and sanitizers. Frequent use of alcohol-based sanitizers can dry up the skin, and the effect is worsening for individuals with sensitive skin. Alcohol-based disinfectants are flammable and can ignite if used near a flame, spark, or other source of ignition. It is important to find safe and effective disinfectants and sanitizers like Hypochlorous Acid (HOCl) to combat COVID-19. EW is an oxyacid of chlorine containing monovalent chlorine that serves as an oxidizing or reducing agent. Hypochlorous acid, commonly known as electrolyzed water, is an oxyacid of chlorine containing monovalent chlorine that acts as an oxidizing or reducing agent. It's a weak acid that can only exist in solution because it's exceedingly unstable. In oxidation-reduction reactions, where electrons are transported from one molecule to another, the molecules are electron–accepting. EW is a product generated by electrolysis of a dilute NaCl solution in an electrolysis cell with a semi-permeable membrane that physically separates the anode and cathode while allowing specific ions to pass through Content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence.
