Abstract: Process for producing a formulation that is solid at up to a temperature of at least 60° C., wherein (a) at least one nonionic surfactant of the general formula (I) R1—CH(OH)—CH2-(AO)x—R2 (I) in which the variables are defined as follows: R1 is selected from C4-C20-alkyl, R2 is selected from C8-C20-alkyl, AO are in each case identical or different and selected from C2-C4-alkylene, x is in the range from 5 to 100, is mixed in the molten state (b) with at least one second substance selected from polyethylene glycol and nonionic surfactants which are different from surfactants of the formula (I), confectioned, mixed and ground in a mill in the solid state with (c) silica or silicate and (d) at least one auxiliary selected from alkali metal citrate, alkali metal carbonate or at least one chelating agent selected from compounds of the general formula (II) R3—CH(COOM1)-N(CH2COOM1)2 (II) in which the variables are defined as follows: R3 is selected from C1-C4-alkyl, phenyl, benzyl, CH2OH and CH2CH2COOM1, M1 is an alkali metal or a combination of at least two alkali metals. Furthermore granules and their use.
