Abstract:
1. Water-redispersible granules obtained by carrying out the steps of: a) preparing an emulsion, in water, of at least one active substance, at least one nonionic surfactant, and at least one water-soluble or water-dispersible compound, and b) drying the emulsion obtained in step a) to obtain the granules, the active substance being in the form of a hydrophobic liquid, the nonionic surfactant being a polyoxyalkylenated derivative, and the water-soluble or water-dispersible compound being: (i) a polymer obtained by polymerizing at least one monomer (I), at least one monomer (III) and optionally at least one monomer (II), or at least one monomer (I) and at least one monomer (II′), wherein monomer (I) is an ethylenically unsaturated, linear or branched, aliphatic, cyclic or aromatic monocarboxylic or polycarboxylic acid, or anhydride, monomer (II′) is an ethylenically unsaturated, linear or branched hydrocarbon, monomer (II′) has the following formula (R (ii) a polymer obtained by the polymerization of at least one ethylenically unsaturated, linear or branched, aliphatic, cyclic or aromatic, monocarboxylic or polycarboxylic acid, or anhydride monomer (I) and at least one saturated or unsaturated, aromatic or nonaromatic, hydrophobic C (iii) a polypeptide of natural or synthetic origin, comprising at least one saturated or unsaturated, aromatic or nonaromatic, hydrophobic C (iv) a highly depolymerized polysaccharide comprising at least one saturated or unsaturated, aromatic or nonaromatic, hydrophobic C
