The invention pertains to a shaped body suitable for use as acid-releasing body in toilets, which comprises 10-95% of a lactic acid oligomer with an average degree of polymerization between 1.8 and 4. The use of lactic acid oligomers of this type results in the controlled release of lactic acid, which serves to reduce or prevent to the formation of calcium and magnesium deposits in the toilet, contributes to soap scum removal, and has a sanitising and disinfecting effect. The shaped bodies may be used in-bowl or in-cistern. A process for manufacturing the shaped bodies, their use in a toilet, a process for ensuring delayed release of lactic acid, and a toilet provided with the block are also claimed.
