Microbicidal agents are sterilants. 2020-03-26 · Some chemical microbicidal agents are the poisonous gas ethylene oxide, chlorine, alcohols and formaldehyde. Microbiostatic agents include food additives that are used for food preservation. Heat is often used as a microbicidal agent, while cold is sometimes a microbicidal agent but is commonly more of a microbiostatic agent. Sterilization refers to any process that removes, kills, or deactivates all forms of life (in particular referring to microorganisms such as fungi, bacteria, spores, unicellular eukaryotic organisms such as Plasmodium, etc.) and other biological agents like prions present in a specific surface, object or fluid, for example food or biological culture media.

Regulatory Framework for Disinfectants and Sterilants . DISINFECTANTS, ANTISEPTICS, & STERILANTS. Disinfectants are strong chemical agents that inhibit or kill micro-organisms (Table 50–1). Antiseptics are disinfecting agents with sufficiently low toxicity for host cells that they can be used directly on skin, mucous membranes, or wounds. Se hela listan på hospitalmanagement.net Microbicidal agents are described which contain, as active substances, toxicologically acceptable odourless or faint-smelling organic acids as well as alkylsulphonates and/or alkyl sulphates. While the individual components have no microbicidal action when used at the application concentrations, their combinations surprisingly show a bactericidal, fungicidal and also virucidal activity.

Antisepsis - Reduction of most microbial life on living tissue. Disinfection - Reduction of most microbial life on inanimate surfaces The solutions of the microbicidal agents were contaminated with heparinized blood up to a concentration of 4% immediately before starting the disinfection and 24 hours before, respectively. After a period of action lasting 1 hour at 20 degrees C, the relative number of test germs capable of multiplying (N/N0) was determined. Objective: Several kinds of functional water are used in the fields of food hygiene and medicine.
