Definitions

  • the present invention relates to a process for the continuous preparation of a granular detergent composition or component having a high bulk density and good flow properties.
  • crystalline Zeolite A which is a water-insoluble, crystalline material well-known in the detergent art as a builder which is particularly suited to removing cations such as calcium and magnesium from hard water.
  • Crystalline Zeolite A is a very finely divided powder. It has been common practice to process the finely divided powder into the form of larger granules (typically 400 to 1000 micrometers) before incorporation into finished products, especially finished detergent compositions. Various granulation processes are known including spray drying and agglomeration. Conventional agglomeration processes in which Zeolite A is used as one of the components have long been known in the prior art :
  • GB2005715 published on 25th April 1979 describes an agglomeration process based upon Zeolite A.
  • the Zeolite A is agglomerated along with carbonate/bicarbonate to make nonionic surfactant agglomerates.
  • the Zeolite A is agglomerated with a high active, neutralised surfactant paste in a high speed mixer and a moderate speed mixer/agglomerator to make anionic surfactant agglomerates.
  • EP521635 published on 7th January 1993, discloses granular detergents made using from ' 10% to 100% of Zeolite MAP.
  • Zeolite MAP has a different chemical composition to Zeolite A.
  • the oil absorbing capacity of Zeolite MAP is 41.6 ml/lOOg, and that this is higher than measured samples of Zeolite A for which it is 26 to 35.5 ml/lOOg.
  • modifying the chemical structure of conventional crystalline Zeolite A i.e. modifying the stoichiometric ratios of Si, Al, Na, 0, H is not always desirable because other properties and characteristics cf the Zeolite are necessarily affected.
  • the object of the invention is to provide a granulation process for making granular detergents which incorporates highly absorbent crystalline Zeolite into granular agglomerates, without losing any of the builder capabilities, especially calcium exchange capacity and calcium exchange rate.
  • this object is achieved by using a modified crystalline Zeolite A having higher oil absorption capacities in a process as specified in claim 1.
  • the Zeolite A has modified physical characteristics (i.e. crystallinity, surface area characteristics, moisture level etc.) rather than a modified chemical structure in order to achieve an oil absorbing capacity of at least 40 ml/lOOg. In this way the excellent builder properties of Zeolite A may still be utilised.
  • a process for the preparation of a granular detergent composition or component having a bulk density greater than 650 g/1 comprises the step of dispersing a liquid binder throughout a powder stream in a high speed mixer to form granular agglomerates, wherein the powder stream comprises crystalline zeolite A having an oil absorbing capacity of at least 40 ml/lOOg, preferably at least 45 ml/lOOg and most preferably at least 50 ml/lOOg.
  • the granular agglomerates are formed by mixing in the high speed mixer for a residence time of from about 2 seconds to about 30 seconds, followed by the step of further mixing in a moderate speed mixer/agglomerator for a residence time through the moderate speed mixer of less than about 5 minutes, preferably less than about 2 minutes, in which, optionally, a finely divided powder may be added.
  • the liquid binder is a surfactant paste, an organic polymer or silicone oil.
  • Surfactant paste may comprise anionic, nonionic, cationic, amphoteric, zwitterionic surfactants, and mixtures thereof; anionic and/or nonionic surfactants being most preferred.
  • Granulation in the context of the present invention is defined as a process of making a granulated product which is an agglomerate of particles that itself behaves as a particle (according to S.A. Kuti, "Agglomeration - The Practical Alternative", published in Journal American Oil Chemists' Society, Volume 55, January 1978).
  • the granular agglomerate is defined herein as the product of such a granulation process.
  • Kuti goes on to state that "the agglomerate is usually formed by blending solids with liquids that serve as adhesive agents. But a lump-free liquid-solids blend is often a difficult task to produce.”
  • the "solids” referred to by Kuti will comprise crystalline Zeolite A having certain physical characteristics to be defined in more detail below. It has now been found that this choice of “solids” contributes greatly to fulfilling the task of producing a lump-free liquid-solids blend.

  • the Zeolite A materials herein are still further characterized by their calcium ion exchange rate which is at least about 2 grains Ca ++ /gallon/minute/gram/gallon (0.13g Ca ++ /litre/minute/gram/litre) of aluminosilicate (anhydrous basis) , and generally lies within the range of from about 2 grains/gallon/minute/gram/gallon(0.13g Ca ++ /litre/minute/gram/litre) to about 6 grains/gallon/minute/gram/gallon (0.39g Ca ++ /litre/minute/gram/litre) , based on calcium ion hardness.
