Abstract

Process for the preparation of a powdery mixture which contains at least alkali metal silicates with a molar ratio SiO 2 : M 2 O, M = sodium and / or potassium, in the range from 1.8 to 4.0 and nonionic surfactants, characterized in that
  • a) drying an aqueous solution which contains the alkali metal silicates to give a solid product,
  • b) pulverizing the solid product obtained in sub-step a), if it is not already in the form of a powder, and isolating the fraction with a particle size in the range from 0.2 to 0.6 mm, unless the powder already consists exclusively of this fraction, and
  • c) the nonionic surfactants are applied to the powder with a particle size in the range from 0.2 to 0.6 mm in such an amount that the weight ratio of nonionic surfactants: the solid product obtained in sub-step a) is greater than 0.5. Use of the powdery mixture in washing, auxiliary washing or cleaning agents; Process for the preparation of such agents by mixing the powdery mixture with other components.
