Abstract
a. L'invention concerne la fabrication de percarbonate de sodium sous forme de particules résistant à l'humidité b. Les particules sont constituées d'un noyau de percarbonate et d'un enrobage d'un mélange de perborate de sodium déshydraté en poudre, de silicate de sodium et de substances chimiquement neutres vis-à-vis des sels précédents. c. Ces particules sont plus solubles aux basses températures de lavage que le perborate et sont en conséquence préférables dans les lessives utilisées à la température ambiante pour les travaux ménagers.
