Title
(EN) FLUIDIZED BED LOW DENSITY GRANULE
(FR) GRANULE DE FAIBLE DENSITE SUR LIT FLUIDISE
Abstract
(EN)
The present invention provides low-density enzyme-carrying granules that are low-dusting and/or storage-stable, and especially suitable for use in liquid detergents and cleaners, such as non-aqueous liquid laundry detergents. Preferred granules of the invention include a relatively high content of one or more low-density fillers, such as perlite or starch, to provide a desired product density. In one embodiment, the granules have a true density within a range of from about 1 to about 1,4 g/cm3. The granules can be economically produced in commercial quantities using fluidized bed technology.
(FR)
L'invention concerne des granules porteurs d'enzymes de faible densité et à faible taux de poussières/ou stables au stockage, qui sont destinés à être utilisés en particulier dans des détergents et des agents de surface liquides, tels que des détergents à lessive liquides non aqueux. Les granules de l'invention contiennent de préférence une concentration relativement élevée d'une ou de plusieurs charges de faible densité, par exemple, la perlite ou l'amidon, afin d'obtenir la densité désirée du produit. Selon un mode de réalisation particulier, les granules ont une masse volumétrique absolue comprise entre environ 1 et environ 1,4 g/cm3. Les granules peuvent être produits de façon économique en quantités marchandes au moyen de la technologie du lit fluidisé.
