    • A free flowing particulate heavy duty laundry detergent containing no more than 8.7% of phosphorus (from phosphate) is comprised of sodium tripolyphosphate particles having nonionic detergent in the interior and on the surface thereof, which adheres a coating of smaller particles of ion-exchanging zeolite to the phosphate. Also within the invention is a method of making such a product by pre-mixing spray dried sodium tripolyphosphate particles and smaller zeolite particles and admixing with them, as by spraying, in liquid form, onto moving particles, a normally liquid or pasty nonionic detergent, such as a higher fatty alcohol polyethylene oxide condensation product, which penetrates the sodium tripolyphosphate particles and adheres zeolite particles to the surfaces thereof.
