The title compositions exhibit superior efficacy as conditioners in the flotation of coal. These compositions are prepared by condensing diethanolamine with a C.sub.10 -C.sub.24 fatty acid in a molar ratio of 1:2 and then introducing one-half the equimolar amount, relative to the condensate, of C.sub.1 -C.sub.4 alkanoic acid.
