395. The influence of alkalinity on the germicidal action of hypochlorites

Abstract

Survivor curves show that, under conditions likely to be found in practice, hypochlorite solutions of low alkalinity disinfect milk films on surfaces more rapidly than those of greater alkalinity.Dehydration of the milk film results in slower disinfection rates by both neutral and alkaline solutions.Increasing the milk content in the film reduces the rate of disinfection and reduces the effect of the neutral solution to a greater extent than the alkaline.
