A surface active compound is supplied into contact with an oilfield production fluid that comprises a mixture of water and oil including water soluble organics. The surface active compound comprises at least one alkoxylate chain and at least one end group attached to each of the at least one alkoxylate chain. The surface active compound is supplied into the oilfield production fluid at a dosage rate that is effective to self-associate at interfaces between the water and oil and inhibit the water soluble organics in the oil from entering the water when the oilfield production fluid is depressurized.
