Abstract: Various liquid or low melting pesticide and herbicide formulations, previously formulated with organic solvents, are combined with a polymer in solution and co-precipitated to form a polymer complex which captures the pesticide or herbicide yet exists as a solid at ambient conditions. By preparing the pesticide or herbicide formulation as a solid complex, storage and handling of the formulation is possible without the potential for organic solvent emission. When the solid polymer complex is placed in water, a stable aqueous dispersion of the pesticide or herbicide is achieved as the polymer inhibits flocculation, with approximately 100% recovery of the pesticide or herbicide.

Abstract: Stable, water-based formulations containing high levels of water insoluble UV protectants/insecticides are provided herein as sprayable microemulsions containing a film-forming polymer, e.g. Agrimer.RTM. VEMA ES 425 [poly(methyl vinyl ether-maleic acid monobutyl ester)]. The polymers are solubilized either by partial neutralization with a base, or by emulsification with appropriate emulsifiers. These formulations produce single phase, micro- or mini-emulsions (particle size<1 micron) on dilution with water. The formulations are useful as UV protectants in veterinary use, for protection of UV-labile insecticides, and for "pour on" applications.
