A laundry treatment product, in the form of a sachet containing a particulate bleaching detergent composition containing sodium percarbonate, has at least two compartments to enable the sodium percarbonate to be segregated from certain other ingredients, particularly zeolites. The sachet product exhibits improved bleach stability on storage. Sachets of water-soluble polyvinyl alcohol film are not insolubilised in the wash liquor since no sodium perborate is present to generate insolubilising borate ions.
