Abstract: Coated sodium percarbonate particles having a mean particle size of from 300 to 1600 ?m containing a sodium percarbonate core surrounded by at least one coating layer, the coating layer comprising at least one coating agent and small sodium percarbonate particles of a mean particle size smaller than 100 ?m. Process for the production of these particles by coating sodium percarbonate core particles with at least one coating agent and with small sodium percarbonate particles of a size smaller than 100 ?m. Use of these particles as bleaching agent in detergent compositions and detergent compositions containing them.

Abstract: The stabilization of solid peroxo and peroxy compounds, in particular of sodium percarbonate and acetyl peroxyborate compounds is described, which can be achieved by coating the peroxo and peroxy compounds with a coating material which is a mixture of essentially a) a fatty acid or preferably an alkali metal or alkaline earth metal salt thereof and b) an anionic surfactant from the group of longer chain substituted sulphonates and sulphates.

Abstract: The use of lactobionic acid, lactobionic acid salts and/or lactobionic acid derivatives as covering material is disclosed for coating alkali metal peroxy salts, in particular for coating sodium percarbonate. In an advantageous alternative of the invention, alkali metal peroxy salts are provided with a covering layer that contains as covering materials lactobionic acid and/or lactobionic acid salt mixed with boric acid and/or a boric acid salt as additional covering material. This coating stabilizes the alkali metal peroxy salts and protects them against humidity and decomposition. In another advantageous alternative, lactobionic acid, lactobionic acid salts and/or lactobionic acid derivatives are used in combination with or in particular mixed with an inorganic mineral salt mixture of alkali metal sulphate and alkali metal chloride as additional covering material for coating alkali metal peroxy salts, in particular for coating sodium percarbonate.

Abstract: Particulate alkali metal peroxy salts are stabilized by coating with a crystallized mineral salt mixture of alkali metal sulfate and alkali metal chloride which optionally may additionally contain alkali metal silicate. Particularly suitable alkali metal peroxy salts include peroxypyrophosphate, peroxytripolyphosphate, peroxymonosulfate and peroxycarbonate. The coated peroxy salts are incorporated in bleaching and detergent compositions.

Abstract: Sodium percarbonate particles stabilized by being coated with a solid coating material which contains a mixture of sodium carbonate and sodium chloride, optionally together with one or more auxiliary agents used in the manufacture of sodium percarbonate.
