FIELD OF THE INVENTION The present invention relates to a preservative-free, liquid storage period for a liquid acid-binding composition having a stable pH of substantially 2 to 40% w / v calcium carbonate, b) one or more pH-adjusting agents capable of maintaining the pH of the acid-binding composition. 9.0 and c) optionally contains one or more pharmaceutically acceptable excipients in an aqueous vehicle, wherein the pH of the aqueous acid binding composition is above 9.0. The pH-adjusting composition of the present invention has a pH-resistance of 9.0, preferably 9.5, against microorganism contamination, furthermore, the composition has a very good taste compared to the known compositions. The pH of the compositions according to the invention remains stable throughout their storage time. |
