CEN/TC 276 Surface active agents
Pre Standard
71.100.40 Surface active agents
This European Prestandard specifies the determination of the water number of ethoxylated products up to about 70% ethylene oxide. EO/PO block polymers with water numbers higher than about 23 become hard to interpret. NOTE: The values obtained by this method are not completely identical with the water number obtained in dioxane, in particular water numbers higher than 23.
