Abstract

A process for the removal of a water-insoluble organic compound from a surface and for the recovery of the same by forming an emulsion of the water-insoluble organic compound in water by means of a surface active compound, breaking the emulsion into an organic phase and an aqueous phase and separating the organic phase from the aqueous phase. The process is characterized in that the surface active compound added is an ether phosphate of the general formula <IMAGE> wherein R is a hydrocarbon group containing 8-30 carbon atoms, each A is a group derived from an alkylene oxide containing 2-3 carbon atoms, n is an integer from 1 to 30 inclusive and R1 is hydrogen or the group R-(A)n, wherein A, R and n are as defined above, and that the emulsion is broken by adjusting the pH thereof to pH 7-10. <IMAGE>
