Summary:This invention relates to a solid composition and to a process for preparing a solid composition and in particular to a process for preparing a solid, water-soluble or water-dispersible composition containing a water-soluble material which is not film-forming and a film-forming water soluble material. The invention provides processes for producing solid, water-soluble or water-dispersible compositions comprising non film-forming materials, such as water-soluble agrochemical electrolytes, supported by film-forming polymers. The water-soluble agrochemical electrolytes can be salts of glyphosate. The processes comprise (i) preparing film-forming aqueous media containing (a) film-forming polymers; (b) water-soluble materials which are non film-forming; (c) water-miscible solvents in which the film-forming polymers are soluble and, optionally, (d) solid fillers, and thereafter (ii) drying the film-forming aqueous media to form the solid compositions. The invention also provides compositions produced by these processes.
