ABSTRACT
Suspoemulsions or suspension emulsions are formed via the addition of an emulsified phase containing one or more active ingredients with a bulk phase (typically water) that also contains one or more active materials as suspended solids. Perhaps the greatest challenge in the preparation of suspoemulsions is the physical stabilization of the system. This stability can be imparted through careful choice of surfactants, dispersants, rheological builders and stabilizers, and process control parameters. Besides handling and inventorying advantages, suspoemulsions of biologically complementary active ingredients offer a unique formulation alternative for fitting into integrated pest management (IPM) and resistance strategies.
