Granulates, method for the production and use thereof

A process for producing a formulation that is solid at up to a temperature of at least 60° C., the process comprising:

• mixing in a molten state
• (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, and
• x is in a range from 5 to 100,
• with
• (b) at least one second substance selected from polyethylene glycol and nonionic surfactants which are different from surfactants of the formula (I),
• confectioning the mixture;
• and
• mixing and grinding the mixture in a mill in a 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, and
• M1 is an alkali metal or a combination of at least two alkali metals,
• wherein the components are present in the formulation in quantitative ratios as follows:
• (a) in a range from 15 to 25% by weight of the at least one nonionic surfactant of the general formula (I),
• (b) in a total range from 5 to 40% by weight of the at least one second substance,
• (c) in a total range from 1 to 5% by weight of silica or silicate, and
• (d) in a total range from 40 to 70% by weight of the at least one auxiliary, and
• wherein a fraction of component (b) in the formulation is at least as high as a fraction of component (a).
