AbstractThe foaming of mixed polymer/surfactant solutions was investigated as a function of surfactant chain length for the system consisting of the cationic cellulose ether Polymer JR400 and a series of sodium alkyl sulfates (CnH2n+1SO4Na, n=8, 10 and 12) and sodium decane sulfonate. Foam enhancement by the polymer was observed with all of these surfactants, but the largest effect and best foaming results were found with the shorter chain length surfactants/Polymer JR400 systems, especially the sodium octyl sulfate/Polymer JR400 system. The foaming results correlated with surface viscoelasticity measurements and also with film drainage observations on selected systems.
