Abstract:
PCT No. PCT/EP94/00576 Sec. 371 Date Oct. 2, 1995 Sec. 102(e) Date Oct. 2, 1995 PCT Filed Feb. 28, 1994 PCT Pub. No. WO94/24044 PCT Pub. Date Oct. 27, 1994Sodium percarbonate is often used in the form of coated particles to increase its storage stability in detergents. Sodium percarbonate particles coated in accordance with the invention have a coating containing reaction products from the reaction of a dialkali metal tetraborate or alkali metal pentaborate with aqueous hydrogen peroxide. Preferred coating components are: perborax with the formula Na2B4O7xH2O2, where n =2 or 4. The coated sodium percarbonate particles are produced by coating the percarbonate particles using a solution containing the reaction products mentioned above. Detergent, bleaching and cleaning compositions containing sodium percarbonate particles coated in accordance with the invention are distinguished by very high stability in storage.
