Definitions
- silicates with a higher ratio generally have a lower solubility and frequently they are used in combination with a soluble salt such as an alkali metal carbonate.
- the lower solubility of high ratio silicates is generally observed as both a slow rate of dissolution and as a higher proportion of insoluble material.
- a low rate of dissolution of the silicate adversely affects the bleach stability of a detergent composition.
- Some silicates have a tendency to cake on storage and/or cause caking in a detergent containing them. It is therefore desirable that useful silicates have a low tendency to cause caking either alone or when incorporated into a detergent composition.
- the spray dried material or powdery material dried in a drum with rotating arms, as described hereinbefore can, in general, be compacted to form granules by any suitable means, but a preferred method for compacting the material is to subject said material to a roller compacting process. In this process the material is compressed between rollers.
- Suitable roller compactors include the Alexanderwerk compactors manufactured by Alexanderwerk AG, Remscheid, Germany, the Chilsonator compactors available from Fitzpatrick Company, Elmshurst, Illinois, USA and a roller compactor from Hosokawa Bepex of Minneapolis, USA.
- a roller pressure setting is selected according to the strength of granule desired, higher pressures leading to stronger granules. Generally, roller pressure is between 4 and 25 MPa. If desired, the compacted material from the compactor is fed into a granulator, which forms part of the machine, and forced through a mesh.
- the water content of the compacted granules can be adjusted by adding some water before the material is compacted on the roller compactor. Typically, up to 4 per cent water by weight with respect to spray-dried material can be added. Preferably, the amount is up to 2 per cent by weight of the material. Surprisingly, the addition of water within these limits at this stage of the process has been found to desirably increase the friability of the granules produced.
- the test is based on the fact that while the silicate granules are dissolving the conductivity of the solution will increase.
- the time needed to reach a constant conductivity value is used as a measure of rate of dissolution of the silicate granule at 20° C.
- the bulk density was determined using a two-part bulk density cylinder with a known capacity which was filled with sample.
- the Bulk Density was obtained by dividing the sample weight by the volume of the lower part of the bulk density cylinder.

Abstract
L'invention concerne une composition destinée à être utilisée comme adjuvant dans des compositions détergentes. Cette composition comprend une matière granulaire contenant un silicate de métal alcalin et un carbonate de métal alcalin. Le silicate de métal alcalin présente un rapport molaire SiO2/M2O, M étant un métal alcalin, compris entre 2,4: 1 et 3,0: 1, la quantité de silicate dans les granules, calculée en tant que SiO2, représente au moins 30 % en poids, la quantité de carbonate de métal alcalin dans les granules, exprimée en tant que matière anhydre, est inférieure à 35 % en poids et la quantité d'eau dans les granules est inférieure à 25 % en poids. Un procédé préféré de fabrication de ces compositions consiste à (a) préparer un mélange aqueux d'un silicate de métal alcalin et d'un carbonate de métal alcalin, (b) sécher par pulvérisation ce mélange aqueux et (c) compacter la poudre séchée par pulvérisation ainsi produite de façon à former des granules de cette composition. Dans une variante de ce procédé, le mélange aqueux de silicate et de carbonate est séché et éventuellement granulé dans un tambour contenant une pluralité de bras rotatifs et dans lequel un gaz chauffé est introduit.
