Abstract
For the improvement of foaming properties of surfactants, the effect of the addition of alkylolamides has been investigated.
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.
