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.

Abstract: A free flowing phosphate-free high bulk density particulate heavy duty nonionic laundry detergent is comprised of particles of spray dried base beads containing ion exchanging zeolite and sodium carbonate with which is mixed a particulate water soluble sodium silicate and into which is absorbed a nonionic detergent. The product is made by spray drying an aqueous mixture or slurry of the zeolite and carbonate, mixing with the beads produced a water soluble silicate powder such as hydrous sodium silicate of Na.sub.2 O:SiO.sub.2 ratio of about 1:2 and mixing nonionic detergent in liquid form with the mixture of spray dried base beads and silicate powder and absorbing the nonionic detergent into said mixture.

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.

Abstract: A multi-colored particulate detergent with over 80% of the particles in the 6 to 200 mesh range and consisting essentially of 5 to 30% detergent, 10 to 50% builder and 2 to 13% water and from 0.1 to 20% of the composition of a colored particulate component in the 6 to 140 mesh range and consisting essentially of a builder salt provided with azo dye coating including a polymeric material.
