Description

For the improvement of foaming properties of surfactants, the effect of the addition of alkylolamides has been investigated.<BR>The foaming power and foam stability of sodium alkylarylsulfonate, sodium sperm alcohol sulfate, PEG-nonylphenylethers (P=12, 18) and PEG-laurylether (P=17) have been remarkably improved by adding more than 30% by wt. of lauric diethanolamide or coco-fatty diethanolamide.
