A method for storing a water-soluble undissolved silica-based material, optionally with an incorporated functional agent. The method includes immersing the material in an aqueous liquid phase which is initially saturated with a water-soluble silica-based material which is the same or different than the undissolved silica-based material, such that the undissolved silica-based material does not essentially dissolve into the liquid phase during storage, or the proportion of the amount of the initially undissolved silica-based material to the amount of the liquid phase is such that the liquid phase will be saturated or essentially saturated by a dissolved portion of the water-soluble undissolved silica-based material during storage, which dissolved portion of said water soluble undissolved silica-based material is less than 20%. Also disclosed is a storage package which may preferably be used to store functional agents, delivery devices or implants. |
