MAKON EO/PO Block and Reverse Block Copolymers exhibit low foaming characteristics. Traditionally, the Ross-Miles Method (ASTM D1173-53, 2001) has been used to show the foam profile of surfactants. However, it is hard to differentiate the products with this method due to their low levels of foam from a lack of shear. The Blender Foam
