CA 2290424

A detergent composition having a bulk density of at least 550 kg/m3 comprises a mixture of: (a) a granulate, preferably a mechanically mixed granulate, of bulk density 450 kg/m3 to 1300 kg/m3, comprising surfactant and inorganic material, and (b) a spray-dried adjunct comprising inorganic material, preferably sodium sesquicarbonate or Burkeite, component (a) being present in an amount of from 35 % to 85 % by weight of the total granular product. The adjunct allows the bulk density of the final composition to be adjusted to any chosen value without detriment to other properties, thus providing flexibility to formulate at a range of bulk densities.

Composition détergente ayant une masse volumique en vrac d'au moins 550 kg/m<3>, qui comprend un mélange: (a) d'un granulat, de préférence un granulat mélangé mécaniquement, ayant une masse volumique en vrac de 450 kg/m<3> à 1 300 kg/m<3>, comprenant un tensioactif et une matière inorganique, et (b) un auxiliaire séché par atomisation comprenant une matière inorganique, de préférence de la burkéite ou du sesquicarbonate de sodium, le composant (a) étant présent à raison de 35 à 85 % en poids du produit granulaire intégral. L'auxiliaire permet l'ajustement de la masse volumique en vrac de la composition finale à n'importe quelle valeur, sans que cela nuise aux autres propriétés, ce qui donne de la souplesse de formulation dans une certaine plage de masses volumiques en vrac.
