| abstract |
The invention relates to a powder or paste preparation which forms a stable dispersion in the aqueous medium and in which the particles of the water-insoluble or sparingly soluble component or components are coated with water-soluble polymer or a polymer mixture. Furthermore, the invention relates to a method for improving the beating capacity of the solid particles dispersed in aqueous medium, in which the water-insoluble or sparingly soluble particles are coated with a water-soluble polymer or polymer mixture before being dispersed. The process according to the invention can be used, for example, in the pharmaceutical industry, in the preparation of crop protection agents, in the cosmetic or in the dyestuff industry for the production of aqueous suspensions which are distinguished by a high stability. |
