两性表面活性剂（七）：两性表面活性剂的应用

介绍了两性表面活性剂在许多领域，如个人洗护用品、民用洗涤剂、工业洗涤剂及其他工业中的应用。指出两性表面性剂在个人洗护用品及民用洗涤剂中应用的最大意义可能体现在对其他表面活性剂，特别是阴离子表面活性剂的解毒性，同时指出两性表面活性剂的任何应用都与协合效应或复配效应有很大关系。所有洗涤剂配方都是在成本要求与对表面活性剂及被洗涤对象的应用限制条件之间平取平衡的结果，因此，可以预期在两种情形下会使用两性表面活性剂：一是在不考虑成本的前提下，二是在特殊应用条件下如极端pH等情形。

Amphoteric Surfactants (

Applications of amphoteric surfactants in various fields were introduced such as personal care and toiletries,domestic and industrial detergents and other industrial cases.It was pointed out that the most important significance of applying amphoteric surfactants in personal care products,toiletries and domestic detergents was probably of the detoxification of amphoteric surfactants to the other surfactants,especially the anionic surfactants.It can be say that any application of amphoteric surfactants is related closely to the synergistic effects of amphoteric surfactant with other surfactants.Because all the formulations of detergents are the result of balance between the cost of formula and the tolerance of used surfactants and washed materials to the practical cleaning conditions,it can be forecasted that amphoteric surfactant could be mostly applied in two cases:firstly the expernse being out of considering,secondly being utilized in some special conditions such as extreme pH.
