ABSTRACT:
The invention concerns water re-dispersible granules obtainable by drying an emulsion comprising an active matter in the form of a hydrophobic, a non-ionic surfactant selected among polyoxyalkylene derivatives, and a water soluble or water dispersible compound selected among polymers: (i) obtained by polymerising an ethylenically unsaturated carboxylic acid, or anhydride monomer (I), and an ethylenically unsaturated carboxylic acid polyoxyalkylene ester (III), and optionally an ethylenically unsaturated linear or branched hydrocarbon monomer (II); or obtained by polymerising said monomer (I), and a vinyl type monomer (II′), comprising at least a C2-C10linear or branched, or cyclic aliphatic radical; (ii) obtained by polymerising at least a monomer of formula (I) comprising a hydrophobic graft; (iii) polypeptides of natural or synthetic origin; (iv) highly depolymerised polysaccharides comprising at least a hydrophobic graft.
