  • Patent number: 6784151
    Abstract: A multi-step process for making a granular detergent composition. The processing steps include adding to a mixer a first feed stream selected from a first powder, a first liquid, and mixtures thereof, to form a second feed stream. The second feed stream is added to a fluid bed dryer to form the granular detergent composition, and optionally, a third feed stream selected from a second powder, a second liquid, and mixtures thereof can be added to the fluid bed dryer. The granular detergent composition contains at least about 50% by weight of particles having a geometric mean particle diameter of from about 500 microns to about 1500 microns with a geometric standard deviation of from about 1 to about 2. Further, at least a portion of the particles contain a detersive surfactant or a detergent builder.

  • Patent number: 6635610
    Abstract: A detergent granule and tablets which comprises an anionic surfactant system which comprises an anionic sulphate surfactant and/or an anionic sulphonate surfactant and other detergent active ingredients, the granule comprising at least a first and a second particulate component and optionally a binding agent, characterised in that the ratio of anionic sulphate surfactant to anionic sulphonate surfactant in the particulate components and in the optional binding agent is less than 1:4 or more than 4:1, preferably even less than 1:5 or more than 5:1. The invention also relates to specific granules comprising restricted degree of mixing of anionic sulphonate surfactant and zeolite, anionic sulphate surfactant and carbonate salts and/or restricted degree of mixing of polymeric builder and anionic surfactant, in particular sulphate surfactants.

  • Patent number: 6608021
    Abstract: A detergent composition which has improved solubility or dissolution in laundering solutions, especially in solutions kept at cold temperatures (i.e., less than about 30° C.), is disclosed. The granular detergent composition is aesthetically pleasing to consumers and has improved flowability. The granular detergent composition has optimally selected level of particles having a judiciously selected median particle size diameter with a selected standard deviation. The granular detergent composition also has carefully tailored physical properties such as uniformity parameter, whiteness, circularity and aspect ratio.

  • Patent number: 6555514
    Abstract: A multi-step process for making a granular detergent composition. The processing steps include adding to a first fluid bed dryer a first feed stream selected from a first powder, a first liquid, and mixtures thereof, to form a second feed stream. The second feed stream is added to a mixer to form a fourth feed stream, and optionally, a third feed stream selected from a second powder, a second liquid, and mixtures thereof can be added to the mixer. The fourth feed stream is added to a second fluid bed dryer to form the granular detergent composition. The granular detergent composition contains at least about 50% by weight of particles having a geometric mean particle diameter of from about 500 microns to about 1500 microns with a geometric standard deviation of from about 1 to about 2. Further, at least a portion of the particles contain a detersive surfactant or a detergent builder.

  • Publication number: 20030024997
    Abstract: An air freshening composition including porous carrier particles having a perfume composition entrapped therein, and a second component selected from an inert filer, hygroscopic agent, binder, coating material, moisture providing agent, and mixtures thereof. The composition may further comprise various optional components such as free perfumes, colorants, disintegrants, water swelling agents, porosity modifiers and mixtures thereof. A method for processing the compositions into a solid article includes the steps of entrapping a perfume in the porous carrier particles, heating and incorporating a carrier or binder material. The compositions may be further processed by optionally incorporating a powder inert filler and forming articles from the mixture. The articles may be formed from the compositions through prilling, extrusion, or compaction amongst other techniques.

  • Patent number: 5891838
    Abstract: A bleach-containing detergent composition which contains a peroxygen bleaching compound and a bleach activator is disclosed. The bleach activator is in the form of particles having a mean particle diameter of 200 microns to 2000 microns. Also disclosed are bleach activator particles in the form of substantially cylindrically-shaped extrudates having a mean extrudate length of from about 500 microns to about 3500 microns and a mean extrudate diameter of from about 450 microns to about 850 microns.
