Zusammenfassung:	The invention relates to a process of encapsulating a compound having a solubility in water of at most 10 g/l at 20°C, comprising the steps of a) Providing a silicon alkoxide based prepolymer modified with a polyalkylene oxide compound, b) Dissolving the compound having a solubility in water of at most 10 g/l at 20°C in a silicon alkoxide having an average of at least two alkoxide groups per molecule to form a non-aqueous solution of the compound,c) Combining an aqueous liquid with the modified prepolymer provided in step a) and the non-aqueous solution prepared in step b) to form an aqueous dispersion, and d) Stirring the aqueous dispersion formed in step c) to form an aqueous dispersion of capsules.
