Particulate detergent, bleaching or cleaning compositions containing moisture-sensitive ingredients, for example bleach ingredients, and also containing crystalline aluminosilicate (zeolite), show significantly enhanced stability of moisture-sensitive ingredients, especially sodium percarbonate or certain bleach catalysts, if the exchangeable cations of the crystalline aluminosilicate include cations of a weak monoacidic, for example, ammonium, lithium or hydrogen ions.
Des compositions nettoyantes, détersives ou de blanchiment particulaires contenant des ingrédients sensibles à l'humidité, par exemple des ingrédients de blanchiment, ainsi que de l'aluminosilicate cristallin (du zéolite), peuvent présenter un accroissement notable de la stabilité desdits ingrédients sensibles à l'humidité, en particulier du percarbonate de sodium ou de certains catalyseurs de blanchiment, dans la mesure où les cations échangeables de l'aluminosilicate cristallin comprennent des cations d'une base monoacide faible tels que des ions d'ammonium, de lithium ou d'hydrogène.
