An improved process for the manufacture of alkaline bleaching compositions, especially liquid and/or gel compositions of high solubility and low abrasiveness, useful to the consumer, especially as products for hard surface cleaning, bleaching or disinfectancy. The products are made by a three-stage process and comprise particular chlorine and bromine bleach sources and particular aminofunctional materials such as low-impurity sulfamate. The process has mixing sequences and starting ingredient selections which provide unexpectedly improved product.
On décrit un procédé amélioré de fabrication de compositions alcalines de blanchiment, notamment des compositions liquides et/ou sous forme de gel présentant une grande solubilité et un faible pouvoir abrasif, destinées au consommateur, particulièrement en tant que produits de nettoyage de surfaces dures, de blanchiment ou de désinfection. Ces produits, fabriqués selon un procédé en trois étapes, comprennent des sources particulaires de blanchiment à base de chlore et de brome, ainsi que des matériaux particulaires aminofonctionnels tels qu'un sulfamate à faible teneur en impuretés. Ce procédé comporte des séquences de mélange et des sélections d'ingrédients de départ permettant d'obtenir un produit étonnamment amélioré.
