Highly hydrolyzed polyvinyl alcohol is preferred.Type: GrantFiled: December 23, 1997Date of Patent: February 27, 2001Assignee: Quest International B.V.Inventors: Jeremy Nicholas Ness, Pamela Virginia Irving, Marcus James Goodall

Patent number: 6177397Abstract: A free-flowing agglomerated powder detergent process and the resulting composition includes from about 5% to about 80% of an alkali metal carbonate; from about 5% to about 50% of a detergent surfactant, and, up to about 25% of an alkali metal salt of a carboxylic acid, wherein the carboxylic acid is selected from the group of carboxylic acids that, below a first temperature, have a greater water solubility than the water solubility of its corresponding alkali-metal salt. The alkali metal salt is preferably provided solely by the reaction of (a) a premix comprising the alkali metal carbonate coated with the surfactant (b) a carboxylic acid selected from the group consisting of citric acid, malic acid, and mixtures thereof, and (c) water.Type: GrantFiled: December 17, 1998Date of Patent: January 23, 2001Assignee: Amway CorporationInventor: David Scott Staley

Patent number: 6165968Abstract: This invention relates to a particulate foam control agent comprising from 1 to 30 parts by weight of a silicone antifoam, from 70 to 99 parts by weight of a zeolite carrier for the antifoam, from 1 to 60% by weight of the silicone antifoam of a surface active agent which has been deposited on the zeolite carrier not later than the silicone antifoam and from 1 to 40 parts by weight of a polycarboxylate-type binder or encapsulant, whereby the polycarboxylate-type binder has a pH of 3 or less when dissolved in water. The invention also relates to a detergent composition comprising the particulate foam control agent and a method for the preparation of the foam control agent.Type: GrantFiled: October 20, 1999Date of Patent: December 26, 2000Assignee: Dow Corning S. A.Inventor: Bertrand Lenoble

Patent number: 6162781Abstract: Foam control granules, for use in particulate laundry detergent compositions, comprise a mobile hydrophobic foam control agent, preferably silicone oil in admixture with hydrophobic silica, optionally combined with a mixture of a hydrocarbon such as petroleum jelly and an alkylphosphoric acid salt, sorbed onto a porous absorbent inorganic carrier comprising or consisting of anhydrous sodium carbonate, preferably light soda ash. When such granules are prepared by mixing and granulating in a high shear mixer/granulator, the addition of from 1 to 10 wt % water after mixing and granulation results in granules having improved flow properties.Type: GrantFiled: August 12, 1999Date of Patent: December 19, 2000Assignee: Lever Brothers Company, div. of Conopco Inc.Inventors: Marinela Buscan, Francois Delwel, Angela Di-Pietro

Patent number: 6159920Abstract: A detergent composition comprises detergent particles, each particle having a substantially anhydrous coating comprising a fluorescent whitening agent and a nonionic surfactant. A process for the preparation of the said detergent composition comprises spraying base detergent particles with a substantially anhydrous mixture comprising the fluorescent whitening agent and the nonionic surfactant.Type: GrantFiled: November 9, 1999Date of Patent: December 12, 2000Assignee: The Proctor & Gamble CompanyInventor: Mark William Ridyard
