Specifies a volumetric method for the determination of the cloud point index of non-ionic surface active agents. The method is applicable to weakly alkoxylated non-ionic surface active agents (1 to 5 oxyethylene groups) the hydrophobic group of which is provided by an alcohol, an alkylphenol or a fatty acid (provided that the last has a melting point lower than 30 °C), subject to the product being soluble ni propan-1-ol to the extent of 1 g in 10 ml at 30 ° C. It is equally appliacable to lipophilic bases derived from alcohols, alkylphenols and fatty acids.
