Abstract: A novel emulsion comprising a material which is stabilized by a polymer resin precursor having interface active molecules incorporated therein by reaction from poorly or non-surface active materials is disclosed. The process for producing such emulsions is likewise disclosed.

Abstract: A formulation e.g., a pesticidal formulation in the form of a dispersion comprising a continuous aqueous phase, and a discontinuous phase comprising a non-aaueous material capable of transport through the aqueous phase to cause Ostwald ripening of the dispersion, wherein there is contained within the discontinuous phase a pesticidal material, which may or may not be the said non-aqueous material,wherein the discontinuous phase comprises a stabiliser in an amount sufficient to depress migration of the non-aqueous material through the aqueous phase, and thereby diminish or prevent Ostwald ripening of the dispersion, characterised in that the stabiliser has a molecular weight of not more than 10,000, and is soluble in the discontinuous phase, but insoluble in and not transportable through the aqueous phase. The production of the formulation can be carried out in a metered in-line mixing plant, since the thermodynamics of the mixing process is such that the particle size tends to a predictable value.

Abstract: Microencapsulated compositions, useful, for example, as pesticidal formulations, were prepared a process in which the microcapsules containing the encapsulated material are formed in an interfacial polycondensation reaction carried out in the presence of one polyvinylalcohol, a different polyvinylalcohol is added, and the resulting mixture is spray dried.
