Title
(DE) VERBUNDPARTIKEL MIT ZELLULOSE UND EINER ANORGANISCHEN VERBINDUNG
(EN) COMPOSITE PARTICLES WHICH CONTAIN BOTH CELLULOSE AND INORGANIC COMPOUND
(FR) PARTICULES COMPOSITES QUI CONTIENNENT À LA FOIS DE LA CELLULOSE ET UN COMPOSÉ INORGANIQUE
Abstract
(EN)
Provided are composite particles which exhibit excellent fluidity and high liquid retentivity and which exhibit high fluidity even in a liquid-holding sate. Also provided are composite particles which permit direct compressing in an open feed manner and which suffer from little compressing trouble and exhibit high shapability. When shaped together with an active ingredient, the composite particles provide shaped bodies which have uniform weight, uniform active ingredient content, and high hardness and which suffer from less galling.

(FR)
L'invention concerne des particules composites qui montrent une excellente fluidité et une capacité de rétention de liquide élevée et qui montrent une fluidité élevée même dans un état de rétention de liquide. L'invention concerne aussi des particules composites qui permettent la compression directe dans une sorte d'alimentation ouverte et qui souffrent de peu de problèmes de compression et montrent une capacité de façonnage élevée. Quand elles sont façonnées conjointement avec un ingrédient actif, les particules composites fournissent des corps façonnés qui ont un poids uniforme, une teneur uniforme en ingrédient actif, et une dureté élevée et qui souffrent de moins d'éraillures.
