(FR) COMPOSITIONS DE FAIBLE DENSITE ET MATIERES PARTICULAIRES COMPRENANT LESDITES COMPOSITIONS
Abstract
(EN)
The present invention provides low-density compositions, as well as particulates formed, at least in part, from such compositions. Preferred low-density materials include, for example, hollowspheres, low-density minerals, and low-density wood materials (e.g., sawdust). The low-density compositions of the invention can be formed as particulates, or cores, suitable for use in forming enzyme granules, e.g., marums, layered granules, prills, drum granules, agglomerated granules, or the like. Granules are disclosed having advantageous properties, e.g., low dusting, storage stable, fast enzyme-release profile, low true density, etc. The granules of the invention are especially useful, for example, in liquid detergents and cleaners, such as predominantly aqueous, liquid laundry detergents. In one embodiment, granules are provided having a true, or volumetric, density within a range of from about 0.95 to about 1.4 g/cm3. The granules can be economically produced in commercial quantities by way of a marumerization, drum granulation, fluid-bed spray-coating, pan-coating, or other suitable process.
(FR)
La présente invention concerne des compositions de faible densité, ainsi que des matières particulaires formées, au moins en partie, à partir de ces compositions. Les matériaux de faible densité préférés comprennent, par exemple, des sphères creuses, des minéraux de faible densité, et des matériaux à base de bois et de faible densité (de la sciure, par ex.). Les compositions de faible densité selon l'invention peuvent être utilisées pour former des matières particulaires ou des noyaux, que l'on peut utiliser dans la fabrication de granules enzymatiques, par exemple de marums, de granules stratifiés, de sphérules, de granules de tambour, de granules agglomérés, ou de composants semblables. Les granules sont décrits comme présentant des propriétés avantageuses, comme par exemple un faible empoussiérage, une stabilité à la conservation, un profil de libération enzymatique rapide, une faible densité absolue, etc. Les granules selon l'invention sont plus particulièrement utilisés, par exemple, dans des détergents et nettoyants liquides, tels que les détergents liquides de blanchisserie à prédominance aqueuse. Dans un mode de réalisation, les granules présentent une densité absolue ou volumétrique allant d'environ 0,95 à environ 1,4 g/cm3. On peut fabriquer les granules, de façon économique, dans des quantités commerciales, par marumérisation, par granulation en tambour, par revêtement par pulvérisation en lit fluidisé, par enrobage en cuve, ou par d'autres procédés adaptés.
