Patent ID: 6869914

Claim:
A process for the preparation of an aqueous suspension comprising from 1-25% by weight of one or more water-insoluble solid agrochemical active ingredient(s) having a melting point of <80°C., from 1-40% by weight of a silica-based carrier, from 1-40% by weight of anionic dispersant, and from 40-97% by weight of water, wherein the weight percentages amount to a total of 100%, which process comprises a) providing a melt (i) of the active ingredient(s), b) providing a suspension (ii) of the 1-40% by weight of the carrier, the 40 to 97% by weight of the water, and the 1-40% by weight of the anionic dispersant, and heating the suspension to a temperature above the temperature of the melt (i), and c) adding, with stirring, 1-25% by weight of the melt (i) to the heated suspension (ii).
