Patent number: 6602846Abstract: The present invention relates to a process for preparing uni-core detergent particles having a degree of particle growth of 1.5 or less and a bulk density of 500 g/L or more, comprising the steps of (A-I) mixing base particles for supporting a surfactant which have an average particle size of from 150 to 500 &mgr;m and a bulk density of 400 g/L or more [Component (a)] with a surfactant composition [Component (c)]; (A-II) mixing a mixture obtained in Step (A-I) with a powdery builder [Component (b)] of which primary average particle size is from 3 to 30 &mgr;m; and (A-III) mixing a mixture obtained in Step (A-II) with a fine powder [Component (d)] of which primary average particle size is smaller than that of Component (b). By using the process of the present invention, the uni-core detergent particles which are excellent in the dissolubility and the flowability properties can be prepared.Type: GrantFiled: February 14, 2001Date of Patent: August 5, 2003Assignee: Kao CorporationInventors: Teruo Kubota, Hitoshi Takaya, Motomitsu Hasumi, Hiroyuki Yamashita

Patent number: 6589931Abstract: A granular detergent composition comprising from about 0.01% to about 50% by weight of an anionic sulphonate surfactant, from about 0.01% to about 45% by weight of a hydrotrope, and from about 0.5% to about 5% by weight of a cationic surfactant. The granular detergent composition is substantially free from anionic sulphate surfactant.Type: GrantFiled: July 12, 2001Date of Patent: July 8, 2003Assignee: The Procter & Gamble CompanyInventors: Ganapathysundaram Venkata Ramanan, Noe Hidalgo, Eric S.

Patent number: 6579838Abstract: A laundry composition, preferably to be used in addition to a laundry detergent, comprises an acidic peroxidic liquid, and particles suspended in the liquid. The particles comprise a protective coating around a core which includes at least one active ingredient selected from a chelating agent, a dye-transfer inhibitor, an anti-fading agent, an anti-bacterial agent, a fabric softener, a transition metal compound and an optical brightener. The particles are stable in the acidic peroxidic liquid but dissolve or disperse under alkaline washing conditions. Surprisingly incorporation of active ingredient(s) into particles appears to give better washing results than the dissolution of such active ingredients in such a liquid.Type: GrantFiled: December 21, 2000Date of Patent: June 17, 2003Assignee: Reckitt Benckiser N.V.Inventors: Chris E. Housmekerides, Daniele Fregonese, Luca Zambelli, Dora Zamuner
