The present invention provides a solution for peritoneal dialysis, consisting of at least two single solutions which are combined after a heat sterilization and are administered to a patient, the first single solution containing an osmotic and the second single solution containing a buffer, and one of these single solutions or another single solution containing electrolyte salts. Glucose-like degradation and hydrolysis is avoided during sterilization and storage, while maintenance of a neutral mixture pH is achieved by the osmotic comprising a glucose polymer and/or glucose polymer derivative, and the pH of the first single solution being between 3.5 and 5.0. The present invention further discloses a twin-chambered pouch consisting of a plastic pouch with at least one first chamber and a second chamber, the first single solution being included in the first chamber and the second single solution being included in the second chamber.
