In order to protect a fabric rebuild polymer which undergoes, during a laundry treatment process, a chemical change by which the affinity of the rebuild agent for the fabric is increased, from hydrolysis on storage, the fabric rebuild agent is in the form of a granule comprising fabric rebuild agent, acidic binder, neutral filler and optionally acidic filler. The granule can be post-dosed to a powder detergent composition.
