摘要：
A topical formulation that inhibits the growth of microorganisms comprises an effective amount of an insecticide dissolved in an oil phase comprising a water-miscible or water-soluble surface active agent, a suspending agent, and a non-ionic surfactant, and an aqueous phase comprising one or more preservatives, where the aqueous phase is buffered to a specific pH. The overall antimicrobial efficacy in an emulsion formulation can be enhanced by buffering the aqueous phase of the emulsion to a pH at which the preservative system inhibits growth for a wider variety of microorganism types in the formulation relative to the equivalent formulation in which the aqueous phase is not buffered.一種抑制微生物生長之局部製劑包括有效量之殺蟲劑溶解於油相中及水相,所述油相包括水混溶性或水溶性表面活性劑、懸浮劑及非離子界面活性劑,且所述水相包括一或多種防腐劑,其中所述水相經緩衝至特定pH值。可以藉由將乳劑的水相緩衝至一定pH值,在所述pH值下,保存系統抑制所述製劑中生長之微生物的類型比水相未經緩衝之等效製劑中多,來使所述乳劑之總體抗微生物功效增強。
