Abstract

L'invention concerne un activateur de blanchiment comprenant un composé alkyloxy, son procédé de fabrication et une composition de blanchiment renfermant cet activateur. L'activateur de blanchiment alkyloxy se compose de particules granuleuses formées par liaison de plusieurs poudre fines constituées d'un composé alkyloxy aux fins de l'activation de blanchiment au moyen d'un liant soluble dans l'eau, d'une couche de revêtement formées desdites particules granuleuses. Etant donné que la couche de revêtement empêche l'activateur de blanchiment de venir en contact avec des peroxydes inorganiques et l'humidité dans l'air, l'activateur de blanchiment alkyloxy présente une excellente stabilité en stockage par température et humidité élevées lorsqu'il est mélangé dans une composition de blanchiment à l'oxygène renfermant un peroxyde inorganique.
