Abstract (en)
[origin: WO9115423A1] The invention provides a process to coat dry particles comprising sodium carbonate perhydrate to provide a stable dry particulate solid which releases hydrogen peroxide when contacted with an aqueous solution. The coated particles are readily soluble in water and/or stable when formulated into a solid detergent.
Abstract (fr)
L'invention a trait à un procédé de revêtement de particules sèches comprenant un perhydrate de carbonate de sodium permettant d'obtenir un matière particulaire solide sèche et stable libérant du peroxyde d'hydrogène au contact d'une solution aqueuse. Les particules enrobées sont immédiatement solubles dans l'eau et/ou stables lorsqu'elles entrent dans la composition d'un détergent solide.
