Surface active agents - Foaming power and antifoaming power - Turbine stirring method
Preview
Summary
This European Standard specifies a method for measuring the foaming power of a surface active agent and the antifoaming power of a defoamer with regard to a foaming solution.
The method is applicable to all surface active agents and particularly to low foaming products and antifoaming surface active agents.
However, measurement of the foaming power of solutions of readily hydrolyzable agents does not give valid results, as the hydrolysis products gather in the films of liquid and affect the persistence of the foam.
