Abstract

Des compositions de détergents granulaires pour lessives comprennent un percarbonate de blanchiment et des ingrédients sensibles à l'oxydation, tels que des agents avivant les couleurs, des enzymes, des parfums et analogues. La stabilité au stockage de ces compositions est améliorée par la présence de silicate. Par exemple, la tendance des agents avivant les couleurs, du type stilbène, à produire un jaunissement indésirable en présence du percarbonate est réduite par l'incorporation de silicates dans les granules.
