Page 1 of 80 Control of Microbial Growth Sterilizing Agents kill everything eg heat radiation Disinfectants kill most things Too strong for living tissues eg lysol NH3 Antiseptics. They are most effective against lipophilic viruses less effective against nonlipid viruses and ineffective against bacterial spores Because of their quick evaporation rate it may be difficult to achieve sufficient contact time Chlorine compounds hou Laboratories (BMBL) 5th Edition: Classes of chemical disinfectants Alcohols Aldehydes Chlorine compounds Iodophor Oxidizing agents Phenolic compounds Quaternary ammonium compounds (QUAT 5.

The destruction of microbiological pathogens is essential and almo Antiseptics. physical or chemical agents that prevent putrefaction, infection, and analogous changes in food and living tissue by destroying or arresting the development of microorganisms. Since ancient times food has been preserved by the use of antiseptic agents such as heat in cooking; niter, salt, and vinegar in corning and pickling; and wood smoke (containing creosote, chemically similar to carbolic acid) in the smoking of meats. In modern times the principal antiseptic agents used in the preservation of food are heat and cold in such processes as canning, pasteurization, and refrigeration. . Radiant energy released by certain electromagnetic processes . Divided into a spectrum based on wavelength. Longer wavelength: lower in energy. Radio waves, microwaves, infrared . Shorter wavelength then visible light: higher energy level . Role of Antiseptics and Disinfectants. Used to reduce microbial growth and contamination from exogenous sources and reduce the risk of infection. Usually chemical solutions that are topically applied to surfaces such as skin, mucous membranes, or inanimate objects. C&D Disinfectants. Adapted from the FAD . PReP. /NAHEMS .
