ABSTRACT:
Polyglycerol esters have been found to be effective antifoam agents in aqueous systems employed in paper processing. Adjunct antifoam agents are not required. Best results are obtained with polyglycerol esters having a degree of glycerine polymerization in the range of 3 to 6 and an esterification range of 15 to 85%.
