Patent number: 6080711Abstract: A powdered laundry detergent is provided with (a) a powder laundry detergent base that includes an inorganic carrier and a surfactant and (b) post-added acidulant and discrete whitening agent particles to provide a detergent having improved cool water solubility with bulk color deterioration caused by whitening agents being minimized. The detergent includes from about 5% to about 80% of an inorganic carrier, from about 1% to about 90% of a detergent surfactant, from about 0.1% up to about 15% of an acidulant and from about 0.1% up to about 30% of the discrete whitening agent particles. The acidulant is selected from the group of acids that in an acid form are soluble in water in an amount not greater than about 8%, preferably not greater than about 0.7% by weight at 25.degree. C. and in a salt form are soluble in water at least in an amount of about 15% by weight at 25.degree. C. The whitening agent particles include a whitening agent and a surfactant.Type: GrantFiled: March 10, 1998Date of Patent: June 27, 2000Assignee: Amway CorporationInventors: Steven J. Brouwer, Michael J. Wint

Patent number: 6077820Abstract: A process for producing a detergent powder or a composition therefore involving partial granulation in a high or low shear granulator followed by granulation in a very low shear mixer, for example a fluid bed is disclosed. The process allows powders to be produced over a wide range of bulk densities without the use of a spray-drying step.Type: GrantFiled: March 4, 1999Date of Patent: June 20, 2000Assignee: Lever Brothers Company Division of Conopco, Inc.Inventors: Vinodkumar Ramniranjan Dhanuka, Fakhruddin Esmail Pacha
