ABSTRACT OF THE DISCLOSURE Phosphorus-containing surfanctant agents having the sturcture Image wherein Hal is halogen; A is selected from OM, and OY Hal; B is selected from H, OM', and OY Hal; with the proviso that M' is an organic radical; Y may be alkylene, optionally interrupted by up to 3 oxygen atoms, of up to 12 carbon atoms, which alkylene chain may optionally be substitiuted with lower alkyl, alkoxy, hydroxy or hydroxyalkyl, e.g., of not more than 10 carbon atoms each; R is a primary, secondary or tertiary amine habing more than six carbon atomsl M and M' are individually selected from the following: (a) hydrogen, (b) an organic radical selected from alkyl or hydroxyalkyl of up to 6 carbon atoms, polyhydroxyalkyl of up to 10 carbon atoms, glyceryl, cycloalkyl or up to 6 carbon atoms, aryl or arylalkyl of up to 10 carbon atoms, or (c) a salt radi- cal selected from alkali metals (e.g., sodium or potassium), alkaline earth matals (e.g., magnesium or caldium), and mono-, di-, or triethanolamine. Preparation of these agents by react- ing a phosphorus ester reactant selected from phosphate di- and tri-esters and phosphite di-esters, having either a labile halogen or a cyclic structure susceptible to nucleophilic attack, with an amine having at least 6 carbon atoms, to produce said surface active agents. These agents quite unexpectedly exhibit good foam volume and superior foam stability in comparison to commerically available amphoteric and zwitterionic surfact- ants.
