Identify the methods of action and preferred uses of chemical disinfectants.
Phenol- disruption of plasma membrane, denaturation of enzymes//rarely used except as a standard of comparison; seldom used as a disinfectant or antiseptic bc of its irritating qualities and disagreeable odor
Phenolics-disruption of plasma membrane, denaturation of enzymes//environmental surfaces, instruments, skin surfaces, and mucous membranes; derivatives of phenol that are reactive even in the presence of organic material
Bisphenols-probably disruption of plasma membrane//disinfectant hand soaps and skin lotions; triclosan is an esp common ex. of a bisphenol. broad spectrum but most effective against gram-pos
biguanides (Chlorhexidine)-disruption of plasma membrane//skin disinfection, esp for surgical scrubs; bactericidal to gram-pos and gram-negs; nontoxic, persistent
