Nephropathy in the Wiskott-Aldrich Syndrome

The invention relates to anti-fouling agents capable of decreasing the fouling of equipment in contact with a hydrocarbon charge. These agents comprise at least one compound selected from the group consisting of substances having the formula: where R and R' are linear or branched alkyl radicals having between 4 and 12 carbon atoms and where M is a metal atom of Groups IA and IIA of the Periodic Table, with n=1, when the metal M is a metal of Group 1A, and n=2, when the metal M is a metal of Group IIA. An example of such an agent is sodium di-2-ethylhexylsulfosuccinate.
