Disclosed is a method for producing composite materials by reactive spray drying, wherein a liquid phase A, which contains inorganic cations, and a liquid phase B, which contains anions that form a salt which is insoluble in the mixture of the fluid phases in conjunction with the inorganic cations, are jointly sprayed with at least one multi-material nozzle, and wherein at least one hydrophobic active ingredient is present in dissolved form in at least one liquid spraying phase, and wherein the salt formed from the cations of phase A and the anions of phase B has a solubility of less than 0.02 mol/l in the neutral aqueous milieu. |
