Is Beta-Propiolactone used for sterilization?
Propiolactone is a disinfectant used for the sterilization of blood plasma, vaccines, tissue grafts, surgical instruments, and enzymes. It has been used against bacteria, fungi, and virus. It is currently FDA approved for its use as an indirect additive used in food contact substances.
What does beta-Propiolactone do?
beta-Propiolactone is used for vaccines, tissue grafts, surgical instruments, and enzymes, as a sterilant of blood plasma, water, milk, and nutrient broth, and as a vapor-phase disinfectant in enclosed spaces.
How does formaldehyde bring sterilization?
Low-temperature steam with formaldehyde is used as a low-temperature sterilization method in many countries, particularly in Scandinavia, Germany, and the United Kingdom. The process involves the use of formalin, which is vaporized into a formaldehyde gas that is admitted into the sterilization chamber.
What chemical agents are used for sterilization?
Chemical sterilization involves the utilization of certain chemicals so as to cause microbial termination. For this, the most used materials are chlorine, formaldehyde, glutaraldehyde, quaternary ammonium salts, and ETO.
Is glutaraldehyde a disinfectant?
Glutaraldehyde is used as a cold sterilant to disinfect and clean heat-sensitive equipment such as dialysis instruments, surgical instruments, suction bottles, bronchoscopes, endoscopes, and ear, nose, and throat instruments.

How does BPL inactivate virus?
BPL modifies the structure of nucleic acids after reaction mainly with purine residues (notably guanine). It induces nicks in DNA, cross-linking between DNA and proteins as well as between the DNA strands in the double helix. Consequently, BPL is widely used for the inactivation of viruses (DNA and RNA viruses).
How long does it take glutaraldehyde to sterilize?
Contact times of at least 20 minutes (at or above 20°C) are effective for high-level disinfection. Sterilization requires a 10-hour contact time and higher concentrations of glutaraldehyde (e.g., Cidex Plus, which contains 3.4% glutaraldehyde), or formulations that combine glutaraldehyde with another disinfectant.
