Detergent compositions in the form of tablets for fabric washing or regions of such tablets contain 30 to 65% by weight of particles which contain 20-5-% of non-soap surfactant and also contain water-insoluble detergency builder. The non-soap surfactant is a mixture of anionic and nonionic surfactants where the amount of anionic surfactant is from 1.5 to 5 times the amount of nonionic surfactant. These particles are accompanied by at least 15% of materials which is other than soap or organic surfactant and which promotes rapid disintegration of the tablet in water. The preferred material is a highly water-soluble salt. The particles form a network which gives both strength and elasticity to the tablet prior to use, while the water soluble material accompanying the particles, promotes rapid dissolution and disintegration at the time of use, thus giving an improved combination of strength when handled, resistance to breakage in transit, and speed of disintegration.
