Abstract: The invention concerns granules obtainable by drying an inverse emulsion, dispersed in an external aqueous phase: a) the inverse emulsion comprising an internal aqueous phase, including a hydrophilic active material, dispersed in an internal organic phase, said inverse emulsion including at least a non-ionic surfactant and/or at least an amphiphilic block polymer, and/or at least a cationic surfactant; b) the external aqueous phase including: at least a polyalkylated non-ionic surfactant and/or at least a polalkylated amphiphilic non-ionic polymer; at least a water soluble or water dispersible polymer in solid form in the presence of a water content of not more than 10 wt. % relative to the weight of said polymer and whereof the glass transition temperature is higher than 25° C., preferably higher than 50° C. The granules, once dispersed, enable to obtain a multiple emulsion.

Abstract: A solid composition containing at least one surfactant with a low melting point and at least one polymer obtained from the following: (i) an unsaturated sulphonic or carboxylic acid and/or unsaturated carboxylic polyoxyalkylenated ester and an optionally unsaturated monomer, optionally comprising the functions of an ester, an amide or an aromatic nucleus; (ii) an unsaturated sulphonic or carboxylic acid, whereby the polymer comprises hydrophobic grafts; (iii) a monomer which is unsaturated and includes hydroxyl groups or hydroxyl precursors, whereby the polymer includes hydrophobic grafts; (iv) polypeptides comprising hydrophobic grafts; (v) polysaccharides which are highly depolymerized and comprise hydrophobic grafts. A method for the production of the composition involves drying an aqueous solution containing the surfactant and the polymer. The composition is useful as a constitutive element of phytosanitary formulations.
