The laundry additive particle comprises a porous carrier core material; a first encapsulating material coated on the core material to form an intermediate layer, the first encapsulating material comprising a glassy material derived from one or more at least partially water-soluble hydroxylic compounds having an anhydrous, nonplasticized, glass transition temperature, T.sub.g, of at least about 0.degree. C.; and a second encapsulating material coated on the intermediate layer to form an outer layer, the second encapsulating material comprising a carbohydrate material having an anhydrous, nonplasticized, glass transition temperature, T.sub.g, of at least about 130.degree.0 C.; and the laundry additive particle has a hygroscopicity value of less than about 80%. Preferably, a laundry or cleaning agent such as a perfume is supported on or contained in the porous carrier.Type: GrantFiled: September 18, 1998Date of Patent: February 15, 2000Assignee: Procter & Gamble CompanyInventors: Athanasios Surutzidis, Michael J.

Patent number: 5955412Abstract: A powder blend of 95% Sodium metasilicate anhydrous and 5% sodium lauroyl sarcosinate which is hygroscopic. The mixture is formulated for effective use when 11.25 ounces are dissolved in one gallon of water or diluted up to six gallons of water. The constituent powders are added to the drum at their mixture ratio of 95% sodium metasilicate and 5% sodium lauroyl sarcosinate which will form the blend. The drum is resealed with the processing lid trapping only low moisture air inside. The drum is relocated to the blending machine which rolls and tilts the drum for blending for 30 minutes at 16 rpm, which ensures complete and uniform blending of the 2 constituent powders. Next, the drum is removed from the blending machine, and the processing drum lid is removed in the process room ensuring low moisture exposure. A filling lid is installed which includes an auger feed, and the drum is rotated and placed in the filling stand. An air motor is attached to the auger.Type: GrantFiled: November 21, 1997Date of Patent: September 21, 1999Inventors: Sarah E. Post, Donald J. Ashby, Benny Surratt
