1. A granular laundry presoaking/washing composition comprising:
- (A) from about 3% to 20% by weight of a granular fabric treatment mixture, the granules within said mixture comprising(i) water-insoluble, friable microcapsules varying in size from about 5 to 500 microns, each microcapsule consisting essentially of(a) a liquid core containing fabric conditioning agent; and
(b) a solid thin polymeric shell completely surrounding said core;
said shell having an average thickness ranging between about 0.1 and 50 microns; and
(ii) a substantially water-insoluble, fabric substantive capsule transfer agent having a melting point between about 40°
C. and 150°
C.;
said capsule transfer agent surrounding each microcapsule;
the weight ratio of microcapsules to capsule transfer agent within each granule of the fabric treatment mixture between about 0.002;
1 and 2000;
1; and
(B) from about 5% to 90% by weight of a presoaking/washing adjuvant selected from the group consisting of water-soluble detersive surfactants, detergency builders and mixtures of water-soluble detersive surfactants and detergency builders.
