  • Further compositions A',B' were prepared in the same way as compositions A,B respectively but using detergent composition II of Table I which contains clay flocculating agent.
  • composition one wash cycle four wash cycles 1.
  • compositions a,b,a',b' respectively as in example I were prepared except for using 5g of polysiloxane, i.e. 1% of the weight of the clay.
  • the polysiloxane used in this example II was Silwet ® L720 from Union Carbide. Result comparison of composition one wash cycle four wash cycles 3. a to b - 0.2 0.1 4. a' to b' 0.3 0.6
  • detergent compositions can be used together with the clay-siloxane agglomerates and flocculating agent.
  • Alternative granular detergent compositions are listed in Table II.
  • the fabric treatment composition as aqueous dispersion the following composition showed excellent softening performance when added in an appropriate amount to the last rinse of the wash : 80g of smectite clay are dispersed in 1 kg of water. 8g of siloxane as described in example I or II are added under strong agitation. The flocculating agent and this mixture are added together to the last rinse of the wash.
  • a stabilized aqueous dispersion of the fabric treatment composition is prepared by using a propeller mixer at rotation of 100 to 1000 per second and combining liquid carrier, softening clay, siloxane and an antisettling agent in said propeller mixer for about 30 minutes.
  • the resulting mixture is then passed 4 to 10 times through a colloid mill (e.g. model SD-40, distributed by Tekmor R Corporation) providing a shear of 10-40x103 per second at a temperature of 20-40°C. Then the flocculating agent is added slowly using said propeller mixer for an additional 5 minutes.
  • a colloid mill e.g. model SD-40, distributed by Tekmor R Corporation
  • the resulting mixture is stable, i.e. shows now phase separation or settling of the clay, for several weeks at ambient conditions.
