Abstract: A method of manufacturing a dosage form is described wherein a liquid solution of a biologically compatible polymer containing a suspension of particulate material that is insoluble in the polymer is supplied to a liquid supply tube (2) having an outlet (2a) and an electrical field is established between the outlet (2a) and a surface (19) spaced from the outlet (2a) to cause liquid issuing from the outlet to form a jet which dries to form a polymer fibre containing particles of the particulate material and which deposits onto the surface (19) to form a dosage which consists of said particulate containing fibre which fibre dissolves or disintegrates in a wet environment such as the mouth.

Abstract: The present invention provides a manufacturing process for quick dissolving products having active ingredients directed to agrochemical applications, such as plant applications and animal and animal health applications. Electrohydrodynamic (EHD) spraying is used to form a product form preferably comprised of fibers that contains a desired agrochemical compound formulated to quickly disintegrate on contact with a solvent such as water. The dispersed chemical is then provided as a sprayable solution. Because the product form contains little or no liquid, significant size and weight savings are gained, higher active ingredient loadings may be placed in a smaller amount of material, and manufacturing, packaging and transportation costs are thereby reduced without impacting user-friendliness. In addition, the EHD manufacturing method of the present invention also permits combining active ingredients previously not capable of effective use together in a single product.
