EO nature
Ethylene oxide, also known as ethylene oxide, molecular formula C2H4O. Boiling point 10.4 ℃, soluble in water, in the air, the explosion limit of 3% to 100% (volume). Ethylene oxide is a highly volatile, explosive, flammable and toxic substance, volatile with ether odor, carcinogenic to humans, is a spectral sterilizer.
EO Sterilization Principle
Ethylene oxide can effectively kill a variety of microorganisms, including bacterial propagules, spores, viruses and fungal spores, and is a broad-spectrum and highly efficient sterilizing agent. Ethylene oxide molecule can alkylate with the carboxyl group (-COOH), amino group (-NH2), dehydrogen group (-SH) and hydroxyl group (-OH) on the gene protein necessary for metabolism in the bacterial cell, replacing the unstable hydrogen atoms on the above mentioned bases and constituting a compound with a hydroxyl ethyl root (-CH2CH2OH), which can affect the reaction base necessary for the metabolism of bacteria by destroying the important metabolism reaction of microorganisms, thus affecting the bacterial reaction. Because this compound destroys the necessary reaction groups in the important metabolic reactions of microorganisms, it affects the action of bacterial enzymes and kills the microorganisms.
