在30摄氏度的温度下，向表面活性剂的丙醇溶液中加入蒸馏水，直到出现浑浊。浊点指数的测定提供了一种表征弱烷氧基化衍生物及其碳氢疏水基团的方法。这种简单而快速的测量对于检查用于磺化等非离子衍生物的烷氧基化水平是一种有价值的方法。

The determination is carried out by adding, at 30 degree Celsius, of distilled water to a propanol solution to the surface active agent until the appearance of cloudiness. The determination of the cloud point index provided a way of characterizing weakly alkoxylated derivates and their hydrocarbon hydrophobic groups. This simple and rapid measurement is a valuable means for checking the level of alkoxylation of non-ionic derivatives intended, for example, for sulphonation.
