Abstract
Abstract A method of thickening an aqueous solution containing from 5 to 50 wt% of a surfactant is disclosed comprising the addition of from about 0.1 to 10 wt% to the solution of a polyether amide derivative having the general formula: wherein R = C₉-C₂₃ and a = 1 to about 5 and b = 1 to 500.
