hydrochlorides and the quaternary ammonium compounds with varying chain lengths (C8–C14) were synthesised. The physicochemical and biological properties were determined in both single and sodium dodecyl sulphate (SDS) mixed systems with a view of enhancing the properties of the individual surfactants as potential ingredients in detergent formulations. The mode of action of the proline surfactants were
合成了一系列由l脯氨酸,游离胺酯,盐酸盐酯和链长不同(C 8 –C 14)的季铵化合物衍生的表面活性剂。为了增强洗涤剂配方中作为潜在成分的单个表面活性剂的性能,在单十二烷基硫酸钠和十二烷基硫酸钠(SDS)混合系统中都确定了其理化和生物学特性。通过脯氨酸表面活性剂与磷脂1,2-二肉豆蔻酰基形成混合胶束的能力研究了脯氨酸表面活性剂的作用方式甘油3磷脂酰胆碱(DMPC)。发现季铵部分的存在和烷基链长度的增加增强了脯氨酸QUAT衍生物的抗菌活性。SDS-C 14 QUAT混合系统在摩尔分数αQUAT: 0.4和0.6时显示出良好的抗菌活性和最佳活性。发现混合体系的抗菌活性是由单体而不是胶束控制的。SDS-C 14 QUAT混合系统还显示出中等刺激性,使其成为去污剂的潜在候选者。
