Process for the production of a pourable phosphate-free foam-inhibiting

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

Free-flowing, particulate foam inhibitor concentrates, which suffer no loss of activity in admixture with surfactants or strong alkalis, are prepared by compacting a mixture of from 1 to 20% by weight of the foam inhibitor with 80 to 99% by weight of a water-soluble salt or salt mixture optionally containing blending aids and having a pH value in the form of a 1% aqueous solution of from 6 to 9.5 under elevated pressure and subsequently size-reducing the compactate to an average particle size of from 0.1 to 2 mm. The presssure applied to the mixture should not significantly exceed the pressure limit at which no further compaction occurs. In addition, the particle porosity, as measured by mercury porosimetry, should be below 10%. The foam inhibitors used are preferably paraffin hydrocarbons, organopolysiloxanes and mixtures thereof with finely-divided hydrophobic solids, particularly finely-divided silica.

Process for the production of free-flowing, stable foam inhibitor

Foam regulators particularly suitable for use in surfactant-containing compositions, comprising a mixture of paraffin hydrocarbons and hydrophobic silica, preferably admixed with a carrier.
