Title (EN) MODIFIED SODIUM CARBONATE CARRIER MATERIAL
(FR) MATERIAU SUPPORT AU CARBONATE DE SODIUM MODIFIE
Abstract: front page image
(EN)A process for preparing a modified sodium carbonate carrier material, the process comprising the steps of: (i) preparing an aqueous solution of sodium carbonate; an effective amount of a crystal growth modifier selected from the group comprising polyacrylates, polyaspartates and polyaspartic acids; and optionally one or more anionic and/or nonionic detergent-active compounds, one or more detergency builders and/or one or more further heat-insensitive detergent components; whereby crystal growth-modified sodium carbonate is formed; (ii) drying the solution to form a dry solid carrier material; (iii) optionally incorporating into the dried solid carrier material one or more detergent components in liquid form and/or mixing the dried solid material with one or more solid detergent components. Also, a modified sodium carbonate carrier material comprising: dry inorganic solids consisting of habit modified sodium carbonate; and polyaspartic acid, or a sodium salt of polyaspartic acid, wherein the weight ratio of polyaspartic acid to the dry inorganic solids is in the ratio from 0.5:100 to 10:100.
(FR)L'invention concerne un procédé de préparation d'un matériau support au carbonate de sodium modifié, lequel procédé comprend les étapes consistant à : (i) préparer une solution aqueuse contenant du carbonate de sodium ; une quantité efficace d'un modificateur de la croissance cristalline choisi dans le groupe formé par les polyacrylates, polyaspartates et acides polyaspartiques ; et éventuellement un ou plusieurs composés anioniques et/ou non ioniques à activité détergente, un ou plusieurs adjuvants de détergence et/ou un ou plusieurs autres composants détergents insensibles à la chaleur ; un carbonate de sodium à croissance cristalline modifiée étant ainsi formé; (ii) sécher la solution pour former un matériau support solide sec ; (iii) éventuellement incorporer dans le matériau support solide séché un ou plusieurs composants détergents sous forme liquide et/ou mélanger ledit matériau avec un ou plusieurs composants détergents solides. L'invention concerne également un matériau support au carbonate de sodium modifié comprenant des solides inorganiques secs, consistant en du carbonate de sodium à l'aspect modifié, et de l'acide polyaspartique ou un de ses sels de sodium, le rapport massique de l'acide polyaspartique par rapport aux solides secs inorganiques variant de 0,5:100 à 10:100.
