The invention relates to a method for producing a formulation which is solid up to a temperature of at least 60 °C, characterised in that (a) at least one non-ionic surfactant is prepared of general formula (I) R 1 -CH(OH)-CH 2 -(AO) x -R 2 (I) in which the variables are defined as follows: R 1 is selected from C 4 -C 20 -alkyl, R 2 is selected from C 8 -C 20 -alkyl, AO are respectively the same or different and selected from C 2 -C 4 -alkylene, x is in the range from 5 to 100, (b) mixed in the molten state with at least one second material, selected from polyethylene glycol and non-ionic surfactants, which are different from the surfactants of formula (I), mixed and ground in a mill in the solid-state with (c) silicic acid or silicate and (d) at least one additive, selected from alkali metal citrate, alkali metal carbonate or at least one chelate forming agent, selective from compounds of general formula (II) R 3 -CH(COOM 1 )-N(CH 2 COOM 1 ) 2 (II) in which the variables are defined as follows: R 3 is selected from C 1 -C 4 -alkyl, phenyl, benzyl, CH 2 OH and CH 2 CH 2 COOM 1 , M 1 is an alkali metal or a combination of at least two alkali metals. The invention also relates to granulates and the use thereof. |
