Abstract: Detergent compositions contain as the active ingredient a polyether ester formed by reacting an alkylene oxide having 2 to 4 carbon atoms with (a) one or more active hydrogen organic compounds and (b) one or more fatty acid esters of fatty acids containing 6 to 30 carbon atoms esterified with one or more mono- or poly-hydric aliphatic alcohols having 1 to 18 carbon atoms, in the presence of an alkaline catalyst. The materials are compatible with the usual additives for detergents, e.g. phosphates, silicates, borates, carbonates, sulphates, alkaline chlorides and sodium carboxymethyl cellulose.ALSO:Surface-active materials are prepared by reacting alkylene oxides having 2 to 4 carbon atoms with (a) one or more active hydrogen organic compounds and (b) one or more fatty acid esters, comprising fatty acids having 6 to 30 carbon atoms esterified with one or more mono- or poly-hydrin aliphatic alcohols having 1 to 18 carbon atoms, at a temperature of from 70 DEG  to 200 DEG  C., and in the presence of an alkaline catalyst.  The substances containing active hydrogen may be primary and/or secondary aliphatic and aromatic amines and their derivatives with one or more amine groups, amine-amides, aromatic and aliphatic amides and sulphonamides and their derivatives with one or more amide groups, aliphatic and aromatic amino-alcohols and their derivatives possessing one or more amine and alcohol groups, amino-phenols, aliphatic and aromatic carboxylic acids and the derivatives with one or more carboxyl groups, e.g. lauric, myristic, oleic and stearic acids, tall-oil (with components fatty acids, resinic acids), fatty acids from tall-oil with or without other resinic acids, fatty acids from mercaptans with one or more thiol groups, phenols and alkyl phenols possessing one or more hydroxyl groups and amino acids and their derivatives with one or more amino and carboxyl groups.  Fatty acid esters include natural and/or synthetic fats and oils, such as mono-, di- and tristearin and mono-, di- and tripalmitin, methyl stearate and palmitate.  In the examples, tallow and ethylene oxide are reacted with the following active hydrogen compounds: oleylamine, ethylenediamine, oleylamide, p-toluenesulphonamide, ethanolamine, diethanolamine, tall oil (containing 25% by weight of resinic acid), oleic acid, n-dodecyl mercaptan, phenol and b -alanine.ALSO:Surface-active materials are prepared by reacting alkylene oxides having 2 to 4 carbon atoms with (a) one or more active hydrogen organic compounds, and (b) one or more fatty acid esters, comprising fatty acids having 6 to 30 carbon atoms esterified with one or more mono- or poly-hydric aliphatic alcohols having 1 to 18 carbon atoms, at a temperature of from 70 DEG  to 200 DEG  C., and in the presence of an alkaline catalyst.
