AC ACTIVE OXIDANT - CIO2 SUPERIOR PERFORMANCE INDUSTRIAL DISINFECTANT

 

Introduction :

In China, life is gradually returning back to normal as corona virus (COVID-19) outbreak has slowed down. Highly effective CIO2 Disinfectant (Active Oxidant) was/is being used to protect all sectors like airports, public transport, aircraft, clinics and medical centers, child care facilities, schools, hotel rooms, health clubs, spas, commercial centers as well as home and offices. It’s to safely and effectively eliminate all microorganisms and provide a long term sanitized environment for working and living. Agex Pharma is also a S Epichlorohydrin (67843-74-7) manufacturer India. 

Formulation/Chemistry

It is a Chlorine dioxide-based , using precursor Sodium Chlorite, alongwith weak food-grade acid solution like Citric Acid. It produces short-lived acidified sodium chlorite (ASC) intermediate which has potent decontaminating properties for hard surfaces by forming Chlorine dioxide as an active oxidant. Chlorine Dioxide is also one of the most effective oxidizing biocide and industrial disinfectant.

CIO₂ gas is a U.S.EPA recognized sterilizer that has been applied for decontamination in the federal buildings. CIO₂   gas has a green-yellowish color and irritating odor and is a volatile and strong molecule. This type of gas is unstable and when photo-oxidized by sunlight it generates the Chloride (CI-), chlorite (CIO-) and chlorate (CIO₃-). In 1814, CIO₂  was  discovered by Sir Humphrey Davy, who produced the gas from the reaction between sulfuric acid (H₂ SO₄) and potassium chlorate (KCIO₃), followed by replacing the H₂SO₄ with hypochlorous acid (HOCI) and the KCIO₃ with sodium chlorate (Na CIO₃). CIO₂ gas has been used for small spaces in patient care rooms due to its penetrating ability. However, some research has argued that gaseous or aqueous CIO₂ performed non-efficient decontamination in the healthcare environment because CIO₂ would break down under ambient conditions to limit its penetrating ability. CIO₂ can also be applied for the disinfection of drinking water by controlling the chemical reaction. The concerning organisms in drinking water are disease causing viruses and pathogens. Bacterial spores in drinking water treatment processes have been investigated using CIO₂ for disinfection. The generated CIO₂ gas is dissolved into the drinking water for further treatment with the desired dose of chemical agent by adjusting the gas flow rate. The application of CIO₂ shows superior inactivation of microorganisms as compared to chlorine (CI₂) , especially in the disinfection of drinking water. The target waterborne pathogens could be eliminated via oxidation of CIO₂.

 Chlorine Dioxide Gas Used in Disinfection and Sterilization

Medical Biocide

To control indoor bio-aerosols and viruses in hospitals and for medical equipment, many aerobiological technologies (i.e., ventilation, filtration, ultraviolet germicidal irradiation, photocatalytic oxidation, ionization and thermal sterilization) and medical biocides such as disinfectors have been developed.

Apart from ozonation, gaseous CIO₂ is another option that is used as an oxidizer or disinfectant in the medical area. CIO₂ can be used in liquid or gas form and is applied effectively against pathogenic microorganisms such as fungi, bacteria, viruses, spore-forming bacteria and bio film.

Key Benefits

AC Active Oxidant shall be sprayed in outside environment, to mop the floors, and wipe the handles, etc. It has similar effectiveness as Ethanol/ Propanol in killing the corona virus (COVID-19). However , the advantage of this product is it can be used in all environament , whereas alcohol cannot be used in flammable area, Petrochemical environment & Kitchen etc.

AC Active Oxidant is more effective than conventional chlorine solution, one of the most commonly used surface disinfectants worldwide. Other chemistries such as alcohols or quaternary ammonium compounds (QACs) can provide  reasonable efficacy against bacteria and fungi, but they are far less effective against viruses and mycobacteria plus have no credible efficacy against bacterial spores in acceptable contact times.

Chlorine dioxide (CIO₂) is  as such used as both a disinfectant and an oxidant in drinking water treatment. It has several distinct chemical advantages, which complement the traditional use of chlorine in potable water treatment.

Chlorine dioxide is highly effective in controlling waterborne pathogens while minimizing halogenated disinfection by-products. Chlorine dioxide is a broad spectrum micro biocide as effective as chlorine against viruses, bacteria and fungi, and more effective than chlorine for the inactivation of the encysted parasites Giardia and Cryptosporidium. Chlorine Dioxide is also an effective control strategy for taste, odor, color, iron and manganese removal.

In hospitals and other healthcare environments , chlorine dioxide helps to sterilize medical and laboratory equipment, surfaces, rooms and tools. It is typically chosen for medical devices disinfection due to their speed and broadspectrum efficacy.

Gaseous ClO₂ has been implemented as a disinfector, sterilizer and oxidizer in different fields. The principle of ClO₂ gas production is the reaction between sodium chlorite and hydrochloric acid. Due to the unstable and easy to decompose characteristics of ClO₂ gas, in-situ production technology needs to be developed. ClO₂ gas can be used for antimicrobial decontamination in the medical area, food processing and odor mitigation because of its high penetration and oxidation ability. In addition, the oxidation of air pollutants such as NO_x, SO_x, Hg, and VOCs using ClO₂ gas has been successfully demonstrated in recent research. Consequently, this mini review provided an overall introduction of ClO₂ gas application. To enhance the ClO₂ processing and treatment efficiency, future priority research directions include development of substantial and reliable ClO₂ gas release systems, combination of for innovative robotic technology for ClO₂ sterilization of epidemic prevention, and evaluation of the effects of ClO₂ dosages on indoor air quality in hospital.

Field Application Details:

1.      Dilute AC Active Oxidant 20 times with water, i.e., add 20 liters of water for every 1 liter of AC Active Oxidant solution

2.      Cleaning staff should wear PPE like protective cover all, surgical mask, protective eyewear and gloves.

3.      Diluted solution can be sparayed / aerosolized for environment disinfection.

4.      After disinfection, cleaning staff should wash their hands thoroughly & discard all PPE.
