Abstract
Stable and flowable aqueous dispersions of at least one water-insoluble material are formulated by dispersing such water-insoluble material, e.g., solid particulates of a plant protection compound, into a homogeneous, stable and flowable aqueous composition that includes (1) at least one water-soluble derivative of a plant protection active agent bearing at least one ionizable functional group and at least one hydrophilic functional group, (2) at least one nonionic surface-active agent and/or at least one aliphatic, cycloaliphatic or arylaliphatic alcohol having from 4 to 15 carbon atoms, and (3) water, this composition exhibiting optical birefringence and a yield point of at least 0.1 pascal.
