US 2025/0049021 A1 · STABLE SUSPOEMULSIONS

Abstract

The present application is directed to a suspoemulsion composition comprising (i) a continuous liquid aqueous phase; (ii) a liquid organic phase emulsified in the continuous aqueous phase, the liquid organic phase comprising a water-insoluble organic solvent and a First Active Ingredient that is solubilized in the organic phase; (iii) a Second Active Ingredient that is solid and is suspended in the continuous aqueous phase, and is at least partially soluble in the organic phase; (iv) a polymeric surfactant in a concentration of more than 0.5 w/w %, with respect to the total weight of the suspoemulsion; and (v) between 0.1 and 15 w/w %, with respect to the total weight of the suspoemulsion, of a polyanionic block copolymer surfactant comprising a hydrophobic moiety and a hydrophilic moiety, wherein at least 60 w/w % of the hydrophilic moiety comprises charged monomers and wherein the weight percentage of the charged monomers is at least 35 w/w % with respect to the total weight of the polyanionic block copolymer surfactant.
