PPT-Chapter 44 Antiseptics and Disinfectants

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.

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. .

Despite the efficacy of sanitizers and disinfectants in preventing disease transmission, the practice of using them has still not improved among the public. Therefore, in this survey, we analyzed the usages of hand sanitizers and disinfectants in the people of the Kingdom of Saudi Arabia. .
