    Abstract: 1. A process for the preparation of surface active compositions by phosphatation by phosphoric anhydride of at least one polyoxyalkylenated derivative R1 -OR-OH (formula (V)), in which formula : O-R represents a succession of identical or different C2 -C4 oxyalkylenated units, in which the number of units can range from 1 to 80, R1 is a C8 -C20 straight or branched chain alkyl or alkenyl radical or an aryl radical of formula (III) see diagramm : EP0252824,P16,F1 in which : m is an integer of 1, 2 or 3 p is an integer of 1 or 2 R3 is a hydrogen atom or a C1 -C4 alkyl radical, and R2 is a C4 -C12 alkyl radical or a radical of the following formula : see diagramm : EP0252824,P16,F2 wherein : R4 represents a hydrogen atom or a C1 -C4 alkyl or phenyl radical ; and optionally neutralisation of the acid functions, the process being characterised in that the phosphatation operation is carried out in two steps : a phosphatation step in the true sense which is effected by continuously introducing phosphoric anhydride into a medium which is subjected to turbulent agitation conditions, the medium being formed by said polyoxyalkylenated derivative containing water in a sufficient amount to initiate the phosphatation reaction, at a temperature of the order of 35 to 40 degrees C at the beginning of the reaction, said temperature being maintained at a temperature lower than or equal to 45 degrees C until the end of the operation of introducing the phosphoric anhydride, the total amount of phosphoric anhydride used corresponding to a polyoxyalkylenated derivative/P2 O5 molar ratio equal to 3 +- 0.3, followed by a step for maturing of the reaction medium obtained, said step being carried out under turbulent agitation conditions at a temperature of between 40 and 60 degrees C.
