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.

Foam regulators suitable for use in detergents and cleaning preparations

A laundry pretreatment composition comprising an invertmicellar ternary mixed phase containing from 5 to 15% by weight of at least one anionic surfactant or from 25 to 45% by weight of at least one nonionic surfactant, and from 50 to 55% by weight of at least one cosurfactant in the presence of an anionic surfactant or from 35 to 50% by weight of at least one cosurfactant in the absence of anionic surfactant, and from 45 to 30% by weight of water in the presence of anionic surfactant and from 40 to 5% by weight of water in the absence of anionic surfactant.
