In general, ... altering the orientation of reactants so that more collisions are effective, reducing intramolecular bonding within reactant molecules, or donating electron density to the reactants. The main attribute of alcohol in increasing the antimicrobial activity is their aptness … Then use it a second time to sanitize. Selectivity of the sanitizer - certain sanitizers are non-selective in their ability to destroy a wide variety of microorganisms while others demonstrate a degree of selectivity. To ensure a sanitizer/disinfectant efficacy, understanding the parameters that affect activity is important but often overlooked by manufacturer. PAA is an effective sanitizer that is active against many microorganisms and their spores. 13. Pesticide behavior is important because all pesticides are poisons deliberately introduced into the environment. Sanitizers are dramatically affected by the pH of the solution.
