Summary Polyethenoxy alkanoates of varying ethenoxy chain length were prepared, and comparative detergency values were obtained on these substances. It was noted that approximately two‐thirds of one ethenoxy group for each carbon atom in the hydrophobic portion of the molecule was essential for optimum detergency values. The nonionic esters prepared from lauric and myristic acids possessed substantially greater detergency than pelgargonic and stearic acids. 12‐Hydroxystearic acid was likewise condensed with ethylene oxide, and curiously enough no ethenoxy groups were found attached to the secondary hydroxyl group. A partial explanation for this behavior based on the addition of ethylene oxide to the hydroxyl group of greatest acidity is presented.
