PULVERFÖRMIGE ZUSAMMENSETZUNG
A pulverulent and mineral oil-free composition which is present as binary system and contains as main constituents a) from 5 to 40% by weight of at least one fatty acid derivative and/or fatty alcohol derivative, b) from 0.5 to 10% by weight of at least one silicone oil and c) from 20 to 85% by weight of at least one support material, with the components a) and b) having been applied to the support material c), is proposed. Suitable components a) are, in particular, fatty alcohol alkoxylates comprising ethylene oxide units and propylene oxide units. Polydimethylsiloxanes are particularly suitable representatives of silicone oils b). The support material c) is selected from the group consisting of chalk, dolomite, shell limestone and silica. The composition has a bimodal particle size distribution in the range from 10 to 120 μm. Such compositions are used, in particular, as antifoams for dry mortar applications.
