Title (EN) COATED SODIUM PERCARBONATE PARTICLES
(FR) PARTICULES DE PERCARBONATE DE SODIUM ENROBÉES
Abstract:
(EN) The coated sodium percarbonate particles of the invention comprise a core which comprises at least 50% by weight of sodium percarbonate, an inner coating layer, which comprises at least 50% by weight of sodium sulphate in the form of thenardite or burkeite, a middle coating layer, which comprises at least 50% by weight of alkali metal silicate, and an outer coating layer, which comprises sodium sulphate and/or sodium carbonate in a fraction of at least 50% by weight.
(FR) L'invention concerne des particules de percarbonate de sodium enrobées comprenant un noyau constitué d'au moins 50 % en poids de percarbonate de sodium, une couche d'enrobage intérieure constituée d'au moins 50 % en poids de sulfate de sodium sous la forme de thénardite ou de burkéite, une couche d'enrobage intermédiaire constituée d'au moins 50 % en poids d'un silicate de métal alcalin, et une couche d'enrobage extérieure constituée de sulfate de sodium et/ou de carbonate de sodium dans une proportion d'au moins 50 % en poids.
