  • Patent number: 4406808
    Abstract: A free flowing, phosphate free high bulk density particulate heavy duty laundry detergent is prepared by spray-drying an aqueous slurry of ion-exchanging detergent building zeolite particles, sodium carbonate and sodium silicate which has been sheared to reduce the viscosity thereof, followed by mixing nonionic detergent in liquid form with the spray-dried base beads to absorb the detergent into the beads.

  • Patent number: 4399048
    Abstract: A free flowing phosphate-free high bulk density particulate heavy duty laundry detergent is comprised of particles of spray dried base beads containing ion exchanging zeolite, sodium carbonate and sodium bicarbonate into which is absorbed a nonionic detergent. The product is made by spray drying an aqueous mixture of the zeolite, carbonate and bicarbonate, optionally with soluble silicate present too, decomposing some of the bicarbonate to carbonate during the drying operation and mixing nonionic detergent in liquid form with the spray dried base beads produced and absorbing such detergent into such beads.

  • Patent number: 4347152
    Abstract: A free flowing phosphate-free particulate heavy duty laundry detergent is comprised of particles of a mixture of sodium carbonate and sodium bicarbonate having nonionic detergent in the interior and on the surface thereof, to which is adhered a coating of smaller particles of ion exchanging zeolite. The product made is exceptionally free flowing and, although the particles are relatively large, is also of high bulk density (over 0.6 g./cc.). Also within the invention is a method of making such products by contacting the particles of mixed sodium carbonate and sodium bicarbonate with a normally liquid or pasty nonionic detergent in the liquid state so that the detergent is largely absorbed by the particles and coats the surfaces thereof, which are then coated with powdered zeolite which adheres to the surface nonionic of the particles and makes them free flowing.

  • Patent number: 4339335
    Abstract: A free flowing, particulate detergent-softener of high bulk density is comprised of nucleus particles of builder salt, preferably a mixture of sodium carbonate and sodium bicarbonate, having nonionic detergent in the interior and on the surface thereof, to which is adhered a coating of smaller particles of ion exchanging zeolite, and quaternary ammonium halide fabric softening compound. In a preferred embodiment of the invention the quaternary ammonium halide is "insulated" from immediate contact with laundry when the detergent-softener is added to the wash water by being added to the nucleus particles with the nonionic detergent, after which the resulting particles are coated with the zeolite powder. In another embodiment of the invention the product described is further coated with nonionic detergent and zeolite.
