Detergent compositions comprising bleach catalysts are disclosed. In particular, components comprising the bleach catalysts are disclosed. In particular, the bleach catalysts are formed into stable particles having low moisture content and low moisture pick-up. Particles are also described having low surface area. Particles containing bleach catalysts are also described comprising a protective agent which reacts with water to form non-water reaction products, particularly preferred protective agents being bleach activators.
La présente invention concerne des compositions détergentes comprenant des catalyseurs de blanchiment ou des parfums. L'invention concerne plus particulièrement des composants comprenant ces catalyseurs de blanchiment ou parfums. En l'occurrence, les catalyseurs de blanchiment se présentent sous forme de particules stables à faible teneur en eau et faible absorption d'eau. L'invention concerne également des particules à faible superficie. L'invention concerne enfin des particules contenant des catalyseurs de blanchiment ou des parfums, comprenant un agent protecteur qui réagit avec l'eau pour former des produits sans réaction à l'eau, les agents protecteurs particulièrement préférés étant des activateurs de blanchiment.
