The present investigation was undertaken to compare the antimicrobial characteristics of amphoteric surface active agent (polyoctylpolyaminoethyglycine, Fu) with that of quaternary ammonium compound (Os) in use as a sanitizer in food plants and in other fields.The antimicrobial activity of Fu against some typical microorganisms seemed to be inferior to Os as shown in Table 1 a) and b).Temperature coefficients (Q_<10>) of microbicidal action of these drugs in a lower temperature range (0°〜20℃) were comparatively larger than the typical chemosterilizer such as halogen compounds and alkylating agents as shown in Table 2 and 3. Concentration exponents (n), computed by the equation, k=AC^n, in which k and C are disinfection constant and drug concentration, resp., were also large ranging from 2.5 to 3.0.From a consideration of the effect of pH and organic matters on the antimicrobial action and other factors such as low-toxicity, wetting ability, deodorising ability, it seems most reasonable to conclude that Fu would be a usefull sanitizer in food plants and in other fields.
