The process further includes the step of adding a flow aid to the particulate detergent composition in a range of from about 0.1% to about 25% by weight of the particulate detergent composition. The process then includes the step of compacting the particulate detergent composition having the flow aid by applying a pressure in an amount sufficient to form the water-dispersible non-particulate detergent product having a density of at least about 1000 g/l. This process enables the manufacture of a rapidly dispersing non-particulate detergent composition that sinks in water.Type: GrantFiled: October 25, 2000Date of Patent: December 17, 2002Assignee: The Procter & Gamble CompanyInventors: Adrian John Waynforth Angell, Les Charles Zorb

Patent number: 6495511Abstract: A process for treating a bentonite having a montmorillonite content of at least 85% which, when activated with sodium ions dried and ground, does not swell more than about 2.5-fold when gradually added to deionised water at room temperature and when crushed dried and calcined to an LoI of less than 4% at 190° C. absorbs 16 to 22% by weight of water in a controlled environment at 25° C. and a relative humidity of 40% by weight, which process comprises the following steps in the following order: i) drying to a moisture content from 25 to 35% by weight; ii) conditioning by crushing, mixing and/or extruding; iii) addition of water to form an extrudable paste having a moisture content of 25 to 40% by weight; iv) extrusion through a die preferably from 4 to 10 mm in diameter; v) drying to a moisture content from 10 to 14% by weight; vi) calcining at 120 to 250° C. to an LoI of less than 4% at 190° C.; and vii) reduction to particles.Type: GrantFiled: January 16, 2001Date of Patent: December 17, 2002Assignee: Colin Stewart Minchem, Ltd.Inventor: Peter Jeffrey Kitching

Publication number: 20020172773Abstract: Rinse aid materials for coating, coating compositions, methods and articles of manufacture for use in automatic dishwashing appliances comprising a nanoparticle system or employing the same to impart surface modifying benefits for all types of dishware surfaces are disclosed. In some embodiments, dispersement of nanoparticles in a suitable carrier medium allows for the creation of rinse aid surface coating compositions, methods and articles of manufacture that create multi-use benefits to modified dishware surfaces. These surface modifications can produce long lasting or semi-permanent multi-use benefits that include at least one of the following improved surface properties: wetting and sheeting, uniform drying, anti-spotting, anti-staining, anti-filming, self cleaning, and durability benefits, relative to dishware surfaces unmodified with such nanoparticle systems.Type: ApplicationFiled: December 13, 2001Publication date: November 21, 2002Applicant: The Procter & Gamble CompanyInventors: Chanchal Kumar Ghosh, William Michael Scheper, Robert Henry Rohrbaugh, Michael Ray McDonald, John David Carter, Eugene Paul Gosselink

Publication number: 20020169090Abstract: A hard-surface cleaning composition for removing cooked-, baked-, or burnt-on food soil from cookware and tableware, the composition comprising a soil swelling agent and a thickening system comprising synthetic smectite type clay thickening agent having an average platelet size of less than about 100 nm. The composition has shear thinning properties and can be used as pre-treatment prior to the dishwashing process. The composition provides excellent removal of polymerized grease from metal and glass substrates.Type: ApplicationFiled: July 19, 2001Publication date: November 14, 2002Inventors: Peter Robert Foley, Howard David Hutton
