GRANULAR COMPOSITIONS

A granular composition, especially for incorporation in washing powder formulations, comprises at least 40 % by weight of an amorphous silica and typically at least 30 % by weight of a functional ingredient such as a perfume, the amorphous silica having a surface area of at least 550 m /g, a pore vo...

Beschreibung
Zusammenfassung:	A granular composition, especially for incorporation in washing powder formulations, comprises at least 40 % by weight of an amorphous silica and typically at least 30 % by weight of a functional ingredient such as a perfume, the amorphous silica having a surface area of at least 550 m /g, a pore volume from about 1.0 to about 2.5 ml/g and a particle size of no more than 50 microns, the granules of said composition having a particle size from about 200 to about 2000 microns. L'invention se rapporte à une composition granulaire, notamment une composition destinée à être incorporée à des formulations de poudre à laver. Cette composition comporte au moins 40 % en poids d'une silice amorphe et généralement au moins 30 % en poids d'un ingrédient fonctionnel tel qu'un parfum, la silice amorphe ayant une aire de surface d'au moins 550 m /g, un volume de pores compris entre 1,0 et 2,5 ml/g et une taille de particule inférieure ou égale à 50 microns, les granules de ladite composition ayant un calibre variant approximativement de 200 microns à 2000 microns.
