Detailed explanation-1: -Which of the following is the characteristics of a sanitizer? Explanation: Sanitizer is an agent that reduces the microbial population to safe levels as prescribed by public health requirements. Usually it is a chemical agent that kills 99.9% of the growing bacteria and are generally applied to inanimate objects.
Detailed explanation-2: -Several physical and chemical factors also influence disinfectant procedures: temperature, pH, relative humidity, and water hardness.
Detailed explanation-3: -Thermal or chemical destruction of pathogenic and other types of microorganisms. Disinfection is less lethal than sterilization because it destroys most recognized pathogenic microorganisms but not necessarily all microbial forms (e.g., bacterial spores).
Detailed explanation-4: -Disinfectants can effectively control infectious diseases by inhibiting or destroying the pathogenic growth, including bacteria and viruses in the transmission medium (Chaturvedi et al., 2021).
Detailed explanation-5: -• Disinfection: Removal of pathogens. • Antisepsis: Removal of pathogens from living tissue. • Degerming: Removal of microbes from a limited area. • Sanitization: Lower microbial counts to safe level. • Biocide/Germicide: Kills microbes.
