Abstract: Disclosed is an inorganic composition which is useful as a base for pharmaceuticals and has excellent stability, and a method for producing the inorganic composition. The inorganic composition contains at least one compound selected from the group consisting of zinc sulfate, zinc chloride, zinc carbonate, zinc hydroxide, and zinc oxide, and has a pH of 7.2 or higher but lower than 8.3. After a dissolution test of the inorganic composition performed by a stirring method, the amount of Zn2* ions released therefrom is 0.1 pg/m2 or larger. This inorganic composition has the excellent property of gradually releasing zinc ions which makes the inorganic composition usable as a base for pharmaceuticals.
