<p>Process for the production of coated sodium percarbonate particles having a dissolution time in water such that less than 50% of the particles are dissolved after 5 minutes in stirred water at 15°C, in which core particles comprising sodium percarbonate are heated and coated with a coating liquid comprising melted carboxylic acid and/or aliphatic alcohols having a melting temperature above 40°C, and the coated particles are then cooled at a temperature below the melting temperature of the carboxylic acid and/or aliphatic alcohols.</p> |
