Abstract

Une composition de blanchiment comprend du percarbonate de métal alcalin comme composé libérateur d'oxygène et des particules de carbonate ou de bicarbonate de métal alcalin d'une grosseur définie (grosseur particulaire moyenne de 250 mum ou supérieure), de préférence moins de 20 % des particules ont une grosseur inférieure à 250 mum, et moins de 5 % des particules ont une grosseur inférieure à 150 mum. La composition de blanchiment particulaire peut être un composant d'une composition pour machine à laver la vaisselle, une composition renforçant le blanchiment ou notamment une composition détergente pour blanchisserie. Le percarbonate a une stabilité à la conservation accrue dans les compositions de l'invention.
