Efficacy Test of Hypochlorous Acid from Thai Rock Salt

Abstract

HOCl is an antiseptic solution for wounds produced from pure salt, with a concentrated free chlorine of 0.05%, pH 6-7 and ORP of 800-950 mV. Traditional Thai medicine uses salt to heal wounds and prevent rotting, giving rise to the idea of developing HOCl from Thai salt, sea salt, rock salt, and pink Himalayan salt to replace high-cost imported HOCl such as Envirolyte™, the purpose of which is to test the composition and physical properties of sea salt, Thai rock salt from 3 sources, and pink Himalayan rock salt from Pakistan compared to pure salt. Salt that has been tested for physical properties and contaminants is produced into Thai HOCl and tested for components. Physical Properties and Performance Compared to the standards of the Centers for Disease Control and Prevention (CDC) and the U.S. Environmental Protection Agency (EPA). Methods A review of the benefits of salt in Thai traditional medicine recipes. Sea salt, rock salt, pink Himalayan rock salt, refined salt, Faraday's Law of Electrolysis, HOCl, Envirolyte^TM. Results HOCl produced from Thai salt had an initial pH of 8.25 and an ORP of 1,100 mV. Efficacy tests showed that 100% concentration reduced germ content (Colony-forming unit (CFU) reduced pathogens up to 0 CFU log 6 in 3 minutes, 15 minutes, 30 minutes, and 60 minutes, concentration of 10% reduced pathogens up to 0 CFU log 6 in 3 minutes, 15 minutes, 30 minutes and 60 minutes, 10% concentration reduced pathogens up to 50 CFU log 5 in 3 minutes, 4 CFU log 5 in 15 minutes, 0 CFU log 5 in 30 minutes, and 0 CFU log 6 in 60 minutes. Thai HOCl was able to reduce the number of bacteria to an undetectable basis throughout the study period. In summary, each salt source has a different amount of sodium chloride and impurities. Rock salt from the South Salt Pond, Bo Klea District, Nan Province is of the best quality, suitable for the production of Thai HOCl, which has properties and efficacy similar to Envirolyte™ and meets CDC/EPA standards. Thai HOCl can be effectively used in general sanitation, food sanitation, and food contact surfaces. Thai HOCl is highly effective against various pathogens at a more affordable price than foreign HOCl with the same standard.
