Patent number: 5854198Abstract: In order to enhance the stability of sodium percarbonate bleach in particulate detergent compositions, crystalline aluminosilicate and a water-soluble alkali metal silicate in an amount of from 1-20% by weight based on the aluminosilicate are included in the non-spray dried base powder. In order to obtain the stabilizing effect, the crystalline aluminosilicate comprises zeolite MAP or the alkali metal silicate is homogeneously dispersed with respect to the aluminosilicate.Type: GrantFiled: March 14, 1997Date of Patent: December 29, 1998Assignee: Lever Brothers Company, Division of Conopco, Inc.Inventors: Peter Willem Appel, Theodorus Johannes Arts, Jelles Vincent Boskamp, Andrew Paul Chapple, Fredericus Cornelis Dobbe, Christophe Michel Joyeux, Carolyn Angela Lanceley, Edwin Leo Lempers, Theo Jan Osinga

Patent number: 5792738Abstract: There is provided a granular, silicate-built, phosphate free laundry detergent composition comprising fine alkali metal percarbonate particles having mean particle diameter below 450 .mu.m, preferably below 400 .mu.m, wherein no more than 20%, preferably no more than 10%, of the particles have a diameter above 710 .mu.m, said particles having a coating comprising one or more soluble inorganic salts. The salts may be selected from alkali or alkaline earth metal carbonates, sulphates, chlorides and nitrates. The coated percarbonate particles have improved stability to storage and are capable of dissolving quickly in wash liquor.Type: GrantFiled: January 16, 1996Date of Patent: August 11, 1998Assignee: The Procter & Gamble CompanyInventors: Gerard Marcel Baillely, Anthony Dovey, Graham Alexander Sorrie, David William York
