新洁尔灭为N-烷基-N,N-二甲基苄基溴化铵的混合物。常温下为黄色胶状体,属阴离子表面活性剂。本品稀溶液具有强力的浸润和渗透作用。刺激性小,配制简单,使用方便,是较佳的杀菌消毒剂。经使用发现,温度低于18℃时新洁尔灭溶液出现混浊,并随温度的降低混浊加重,与文献报道一致。混浊的新洁尔灭液直接影响杀菌效力。为保持0.1％新洁尔灭溶液在18℃以下不产生混浊,提高杀菌效力。笔者通过对不同配方的探讨,选出较为满意的配方,结果如下: 一、取药用1％新洁尔灭100ml加新鲜蒸 Bromogeramine is a mixture of N-alkyl-N, N-dimethylbenzyl ammonium bromide. Room temperature yellow colloid, is an anionic surfactant. This product dilute solution has a strong infiltration and infiltration. Small irritation, preparation is simple, easy to use, is a better disinfectant. It was found that when the temperature was lower than 18 ℃ Bromogeramine solution appeared turbid, and with the temperature decreased turbidity increased, consistent with the literature. Turbidity benzalkonium bromide directly affects the bactericidal efficacy. To maintain 0.1% benzalkonium bromide solution does not produce turbidity below 18 ℃, improve bactericidal efficacy. The author through the discussion of different formulations, choose a more satisfactory formula, the results are as follows: First, take medicine 1% benzalkonium bromide 100ml plus fresh steamed
