Disclosed herein is a process for the preparation of a composition, comprising the following steps: a) adding at least one base to an aqueous solution containing at least one salt selected from iron(III) sulfate and iron(III) nitrate to form a precipitate of iron hydroxide, b) optionally washing the resulting precipitate one or more times with water, yielding an aqueous suspension of the iron hydroxide, c) adding at least one further constituent that inhibits ageing of the precipitate of iron hydroxide obtained in step b), d) drying the composition obtained in step c). Also disclosed are various uses of the compositions obtained, including medical uses. |
