Abstract
A novel group of surface active agents is revealed. These surface active agents are the condensation product of an aldehyde or ketone of from 9 to 20 carbon atoms with a polyoxyalkyleneamine which is an amine terminated block copolymer of oxyethylene and oxypropylene groups. The Schiff bases of the present invention are characterized by the general formula: ##STR1## In this general formula, R.sub.1 and R.sub.2 can either be hydrogen or an alkyl radical such that the sum of carbon atoms in the radical R.sub.1 --C--R.sub.2 is from 9 to 20.
