METHOD FOR STORING SILICA-BASED MATERIAL, PACKAGE PRODUCED WITH THE METHOD AND USE OF PACKAGE FOR PACKAGING OF SILICA-BASED PRODUCTS

摘要

The present invention relates to a method for storing a water-soluble undissolved silica-based material, optionally with a functional agent incorporated therein, to preserve desired property or properties of the undissolved silica-based material and optionally of the functional agent incorporated therein. The undissolved silica-based material is stored by immersing said material in a liquid phase media comprising water wherein the liquid phase is initially saturated with a water-soluble silica-based material, which is the same or different than the undissolved silica-based material, to such an extent that the undissolved silica based material does not at all or 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 said dissolved portion of said water soluble undissolved silica-based material is less than 20%. The present invention also relates to a package for storage according to the method of the invention and to uses of the package preferably for storing functional agents, delivery devices or implants.
