Abstract
Etheramine alkoxylates are described which have the formula: ##STR1## where R.sup.1 is a straight or branched alkyl, aryl or alkylaryl group of 6 to 22 carbon atoms; R.sup.3 are independently hydrogen or C.sub.1 to C.sub.3 alkyl; m averages from about 1 to about 20; and x and y each independently average from about 0 to 30, where x+y averages from about 2 to about 60. These etheramine alkoxylates have surfactant properties. Further, they may be quaternized to make other compounds which will have useful surfactant properties.
