Abstract:
The invention relates to preparations of active substances of low solubility in water, made of carrier particles having coatings containing active substances, wherein the active substances of low solubility are embedded in coatings made of amphiphilic copolymers.
Abstract:
The invention relates to formulations comprising preparations of active substances of low solubility in water in a polymer matrix of polyether copolymers, wherein the polyether copolymers are obtained by radically initiated polymerization of a mixture of 30 to 80% by weight of N-vinyl lactam, 10 to 50% by weight of vinyl acetate, and 10 to 50% by weight of a polyether, and of at least one surfactant in which the active substance of low solubility in water is amorphously present in the polymer matrix.
