Characteristics of Ethylene Oxide Sterilization for veterinary paste syringe

Jun. 24, 2021

The veterinary paste syringe is a new type of packaging with both drug storage and drug delivery functions. It is widely used in pet nutrition creams and dairy cow mastitis drugs. In order to ensure the sterility of the drug, the veterinary syringe must undergo a special sterilization treatment after the production is completed. Ethylene oxide sterilization is one of its more commonly used sterilization methods.

Ethylene oxide, also known as ethylene oxide, is a colorless liquid at low temperatures with an aromatic ether smell. It has a boiling point of 10.8°C, an odor threshold of 760 mg/m~1064 mg/m, and a density of 1.52; ethylene oxide is flammable and easy to use. Explosion, its minimum combustion concentration is 3%. When ethylene oxide acts, its ring structure is broken, and after hydroxylation, it alkylates with amino, carboxyl, hydroxyl and other active groups on the protein in the bacterial body, causing obstacles to the enzymatic metabolism process, thereby destroying the bacterial body. Metabolism causes the death of microorganisms and achieves the purpose of sterilization.

Ethylene oxide sterilization is a chemical sterilizing agent with good sterilization effect, which can kill all microorganisms including bacterial spores. It has strong penetrability and can be used to sterilize various parts that are difficult to penetrate: For example, some thin and long catheters are difficult to achieve sterilization effect with other low-temperature sterilization methods, and only ethylene oxide can be used Or irradiation. Since ethylene oxide kills microorganisms by using the principle of alkylation rather than oxidation, the damage to the veterinary paste syringe is very small, and it has a very wide range of uses for the sterilization of heat-labile precision instruments.
Generally speaking, ethylene oxide sterilization is a sterilization method with longer application time and strong penetrating power, which is very suitable for tubular items such as veterinary paste horse  syringes. It should be noted that ethylene oxide is flammable and explosive, and cannot leak during storage and sterilization. A safe sterilizer must be selected for safe operation and storage.
