  • Patent number: 8080509
    Abstract: The present invention relates to a solid laundry detergent composition having a bulk density of from 100 g/l to 500 g/l, wherein the composition comprises: (a) from 1 wt % to 70 wt % anionic detersive surfactant; (b) from 0 wt % to 10 wt % zeolite builder; and (c) from 0 wt % to 10 wt % phosphate builder; wherein the composition comprises: (I) from 61 wt % to 90 wt % low-density particulate component, wherein the low-density particulate component has a bulk density of from 100 g/l to 426 g/l, and wherein the low-density particulate component comprises inorganic material and organic material; and (II) from 10 wt % to 39 wt % high-density particulate component, wherein the high-density particulate component has a bulk density of greater than 426 g/l; wherein the ratio of (i) the weight ratio of the inorganic material to the organic material comprised in the low-density particulate component (I) to (ii) the weight ratio of the inorganic material to the organic material comprised in the solid laundry detergent co

  • Publication number: 20110241235
    Abstract: The present invention relates to a process of making spray-dried detergent particles comprising the steps: (a) contacting magnesium sulphate with sodium salt of ethylenediamine disuccinic acid to form a premix comprising magnesium salt of ethylenediamine disuccinic acid; (b) contacting said premix with an aqueous slurry comprising detersive surfactant, sodium silicate, and optionally polymer; and (c) spray drying said aqueous slurry to form said spray-dried detergent particles.

  • Patent number: 7947642
    Abstract: The present invention relates to a spray-drying process for the preparation of a spray-dried detergent powder having a bulk density of 426 g/l or less, wherein the spray-dried detergent powder comprises an anionic detersive surfactant and from 0 wt % to 10 wt % zeolite builder and from 0 wt % to 10 wt % phosphate builder, and wherein the process comprises the step of: (a) preparing an aqueous slurry suitable for spray-drying comprising from 30 wt % to 60 wt % water and from 40 wt % to 70 wt % non-aqueous material, wherein the non-aqueous material comprises an inorganic component and an organic component, wherein the weight ratio of the inorganic component to organic component is in the range of from 0.3:1 to 5:1; and (b) spraying the slurry into a spray-drying tower, wherein the temperature of the slurry as it enters the spray-drying tower is in the range of from 65° C. to 140° C., and wherein the outlet air temperature of the spray-drying tower is in the range of from 70° C. to 120° C.

  • Publication number: 20090227486
    Abstract: The present invention relates to a method for making starch encapsulated ingredients where a mixture of starch, water, acid and ingredient for encapsulation is prepared. The mixture is atomised and dried to provide encapsulates that can retain high levels of encapsulated ingredient. When the encapsulated ingredient comprises oil, the invention reduces the levels of free oil on the outside of the encapsulates and surprisingly reduces explosivity of fines produced during the manufacturing process. The preferred acid is citric acid.
