A foam regulator consisting essentially of a mixture, applied to a particulate support material, of (a) 5 to 60% of a paraffin wax, (b) 20 to 90% of a microcrystalline paraffin wax which shows defined melting behavior as a function of temperature and (c) 5% to 20% of a diamide derived from C.sub.2 -C.sub.7 diamines and C.sub.12 -C.sub.22 fatty acids which is present in the paraffin mixture in very finely divided form. The mixture is preferably prepared by reaction of the diamines with the fatty acids in a molten mixture of components (a) and (b) in the presence of an acidic catalyst.
