Patent number: 6797686Abstract: Coated solid bodies comprising a core of an active composition and having a water-soluble or dispersible micro-porous or net-coating. The coating improves the mechanical characteristics of the solid body and allows for good dissolution. The coated solid bodies preferably take the form of detergent tablets.Type: GrantFiled: August 23, 2002Date of Patent: September 28, 2004Assignee: The Procter & Gamble CompanyInventors: Angelina Rena Romero, Lionel Bernard Michel Genix, Christian Gossens

Patent number: 6794354Abstract: A continuous process for preparing granular detergent composition including a first step of dry neutralizing an acid precursor of an anionic surfactant with a particulate water-soluble alkaline material in a high speed mixer for a mean residence time of about 0.2 to about 50 seconds, thereby partly or totally neutralizing the acid precursor and producing a dry neutralized material containing the anionic surfactant, in the form of a free-flowing powder; and a second stop of agglomerating the free-flowing powder into a detergent agglomerate using an agglomeration binder. The agglomeration binder is preferably a viscous surfactant paste binder. The resulting agglomerates are dry, free-flowing, and have a substantially more narrow particle size distribution, compared to the free-flowing powder, with reduced fine particles and over-sized particles that generally are recycled.Type: GrantFiled: March 12, 2001Date of Patent: September 21, 2004Assignee: The Procter & Gamble CompanyInventors: Paul R Mort, III, Millard Edward Sullivan

Patent number: 6790821Abstract: A process for preparing coated detergent granules in a fluidized bed is provided. The fluidized bed is operated at a flux number of at least about 3.5 and/or a Stokes Number of greater than 1.0. Upon drying, the resultant detergent particles have improved appearance and flow properties and may be packaged and sold as a detergent material or mixed with various other detergent ingredients to provide a fully formulated detergent composition.Type: GrantFiled: November 30, 2001Date of Patent: September 14, 2004Assignee: The Procter & Gamble CompanyInventors: Matthew Israel Wasserman, Mark William Ridyard, Scott William Capeci, Wayne Edward Beimesch, Paul R Mort, III
