The physical and surface‐active properties of alkylolamides prepared from methyl‐9,10‐epoxystearate are discussed. These materials are prepared by reacting methyl‐9,10‐epoxystearate with a polyoxyethylene alcohol to produce the methyl ester of the hydroxyalkoxypolyoxyether substituted carboxylic acid which is subsequently subjected to aminolysis with diethanolamine. The properties of the derivatives as a function of the molecular weight of the polyoxyethylene alcohol are explored and appear to exhibit critical changes at a value of about 500. All the materials thus prepared exhibit higher water solubility than corresponding N,N‐di(2‐hydroxyethyl) amides and foam somewhat less. Possible applications for materials such as these include formulation of low‐foam, heavyduty cleaning compounds, both of a liquid and dry type. This would, of course, be especially important in the growing field of automatic liquid dishwater formulations. A need for such materials also exists in heavy‐duty metal cleaning, floor washing, and other heavy‐duty cleaning applications.
