Abstract

Abstract This application relates to novel compositions of matter generally classified as alkanolaminofunctional siloxanes. These compositions have a structure selected from the group consisting of: ##STR1## wherein x represents an integer of from 1 to 100; y represents an integer of from 1 to 10; R 1 represents a lower alkyl group; and M is an alkanolamino group selected from the group consisting of: --(CH.sub.2).sub.a N(R.sup.2)--(CH.sub.2).sub.b OR.sup.3 ; (c) and --(CH.sub.2).sub.a N.sup.+ (R.sup.2)(R.sup.4)--(CH.sub.2).sub.b OR.sup.3 Z -1 (d) Compositions of this invention exhibit utility in altering the surface activity of water.
