Definitions

  • the present invention relates to a process for the production of a detergent composition.
  • the invention is concerned with a process for the production of a detergent composition having a medium bulk density without the use of a spray-drying step involving a high shear mixing step and a very low shear mixing step and to detergent compositions thereby produced.
  • detergent compositions have been produced by a spray-drying process in which the components of the composition are mixed with water to form an aqueous crutcher slurry which is then sprayed into a spray-drying tower and contacted with hot air to remove water whereby detergent particles, often referred to as a "base" powder are obtained.
  • the particles so obtained have a high porosity.
  • powders produced by this method typically have a bull- density of 300 to 550 g/1 or even up to 650 g/1.
  • Spray-dried powders generally provide good powder delivery characteristics such as dispensing and dissolution. However, the capital and operating costs of the spray-drying process are high. Nevertheless there remains a significant consumer demand for such low density powders.
  • detergent powders having a high bulk density have been produced by mechanical mixing processes. Bulk densities of 700 to 900 g/1 and even higher have been obtained. Typically such powders are produced by densifying a spray-dried base powder in one or more mechanical mixers, optionally with the addition of further components, or by mixing the components of the composition in a continuous or batch mixing process without the use of a spray-drying step.
  • EP 367 339 discloses a process for the production of a detergent composition having a high bulk density in which a particulate starting material is treated in a high speed mixer, a moderate speed mixer wherein the material is brought into or maintained in a deformable state, and then dried and/or cooled.
  • the starting material may be a spray-dried base powder or the components of the composition may be employed without a prior spray-drying step in the detergent production process.
  • Powders having a high bulk density have a low packing volume which is advantageous for storage and distribution operations and also for the consumer. Furthermore, if a spray-drying step is not employed, the capital and operating costs are typically much lower and the process uses less energy and so provides an environmental benefit. The avoidance of a spray-drying step in the detergent production process is therefore desirable.
  • EP 544 365 (Unilever) is concerned with the production of a high bulk density detergent composition and refers to the bulk density of a detergent powder being dependent upon the bulk density of the starting materials in the case of a mixing process.
  • Treating a porous spray-dried material in a mechanical mixing process typically leads to an increase in bulk density as the powder porosity is reduced.
  • a powder having a surprisingly low bulk density for example less than 700 g/1, may be obtained by a process in which a spray-drying step is not employed, involving a high shear mixing step and a very low shear mixing step if a component having a low bulk density is incorporated in the very low shear mixing step. Further, such a powder exhibits good powder properties.
  • a first aspect of the invention provides a process for the production of a detergent composition or component having a bulk density of less than 700 g/1 which does not comprise a spray-drying step and which process comprises mixing a particulate starting material with a liquid binder in a mixer granulator, preferably having both a stirring and a cutting action, to form granules wherein the starting material and/or binder comprises a non-soap detergent active or a precursor thereof, feeding the said granules to a very low shear mixing zone and contacting the granules with a particulate material having a bulk density of not more than 700g/l to produce a detergent composition or component having a bulk density of less than 700 g/1.
  • a second aspect of the invention provides a detergent composition or component having a bulk density of less than 700 g/1 obtainable by a process which does not comprise a spray-drying step and which comprises mixing a particulate starting material with a liquid binder in a mixer/granulator, preferably having both a stirring and cutting action, to form granules and feeding the said granules to a very low shear mixing zone and contacting the granules with a particulate material having a bulk density of not more than 700g/l.
  • % figures are on a weight basis and based on the total weight of the detergent composition or component prior to the optional addition of post-dosed ingredients .
  • the detergent composition has a bulk density of 400 to 680 g/1, preferably 450 to 680 g/1 and more preferably 500 to less than 650 g/1. It is further preferred that the detergent composition has a particle porosity of at least 0.2 and more preferably at least 0.25. The porosity may be determined by a mercury porosimetry method.
  • the component incorporated in the very low shear zone has a bulk density of not more than 700 g/1, and suitably has a bulk density of 200 to 600 g/1, preferably 250 to 550 g/1 and especially 350 to 500 g/1.
  • This low bulk density component is desirably an aluminosilicate, for example zeolite 4A or zeolite A24 or a salt, preferably an inorganic salt. Salts, preferably sodium, of phosphates, for example tripolyphosphate, carbonate, bicarbonate and sulphate are especially suitable. Desirably the low bulk density component constitutes the detergency builder, or part thereof in the composition. If desired, this component may be a non-builder material, in which case the particulate starting material will suitably comprise a builder.
  • the low bulk density component comprises sodium tripolyphosphate having a bulk density of 380 to 500 g/1. This compares to a typical bulk density of 800 to 1000 g/1 for tripolyphosphate conventionally employed in detergent compositions.
  • the level of the low bulk density component is selected according to the desired density of the detergent composition. Preferably it is present at a level of 5 to 65 wt %, preferably 10 to 40 wt % and optimally 10 to 30 wt % of the composition.
  • part of the low bulk density component may be introduced into the high speed mixer/granulator.
  • the level of this component in the very low shear mixing zone is at least 10% by ' weight based on the detergent composition and additionally up to 80% of the total amount of the low bulk density component may be dosed into the high speed mixer/granulator although it is preferred that up to 60%, more preferably 5 to 50%, especially 20 to 45% of the low density material (as a percentage of the total amount of this material) be dosed into the high speed mixer granulator.
  • the process may be continuous but is preferably batch- wise.
  • a preferred type of mixer/granulator for use in the process of the invention is bowl-shaped and preferably has a substantially vertical stirrer axis.
  • mixers of the Fukae (Trade Mark) FS-G series manufactured by Fukae Powtech Kogyo Co. , Japan are essentially in the form of a bowl-shaped vessel accessible via a top port, provided near its base with a stirrer having a substantially vertical axis, and a cutter positioned on a side wall.
  • the stirrer and cutter may be operated independently of one another, and at separately variable speeds.
  • Another mixer found to be suitable for use in the process of the invention is the L ⁇ dige (Trade Mark) FM series batch mixer ex Morton Machine Co. Ltd., Scotland. This differs from the mixers mentioned above in that its stirrer has a horizontal axis.
  • Granulation is preferably effected by running the mixer using both stirrer and cutter; a relatively short residence time (for example, 5-8 minutes for a 35 kg batch) is generally sufficient.
  • the final bulk density can be controlled by choice of residence time.
  • the stirrer is operated at a rate of 25 to 80 rpm, preferably 30 to 75 rpm.
  • the cutter is suitably operated at a rate of 200 to 2500 rpm, preferably 300 to 2200 rpm.
  • a batch process typically involves pre- mixing of solid components, addition of liquids, granulation, optional addition of a layering material suitable for controlling the granulation end-point, and product discharge.
  • the rate of stirring and/or cutting is suitably adjusted according to the stage of the process.
  • the binder comprises one or more of the following: liquid detergent-active compound(s) , precursors thereof, water, solutions, non-aqueous or aqueous, of other ingredients or mixtures thereof.

  • the mixing step is preferably carried out at a controlled temperature somewhat above ambient, preferably above 30°C.
  • the temperature is within the range 30 to 55°C although higher temperatures may be suitable, for example, where heat of reaction is generated by in situ neutralisation.

  • the fluid bed is suitably operated at a temperature of 30 to 90°C and at a superficial air velocity of about 0.25 to 1.2 ms "1 .
  • Suitable fluid beds are available from, for example NIRO.
  • the air flow in the fluid bed may be adjusted according to the desired level of shear and agitation of the low bulk density component.
  • the low bulk density component is dosed into the bed and gently agitated using a small air flow which is then increased prior to feeding in the granules from the high speed mixer/granulator.
  • the detergent composition suitably comprises anionic detergent active.
  • anionic detergent active This may be incorporated as a pre- neutralised material, desirably as a component of the particulate starting material, or may be neutralised in situ.
