Adrian J. W. Angell has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5656584
    Abstract: A process for producing a particulate laundry additive composition produces a particulate laundry additive for perfume delivery in laundry detergent compositions, especially those in the form of granules or agglomerates. The process includes mixing a porous carrier material, typically containing perfume, and an encapsulating material, typically a carbohydrate material, and then compacting the mixture to form agglomerates. The agglomerates which include the porous carrier particles enrobed with the encapsulating material are then sized into particles for incorporation into a detergent product. The process may be employed to produce particulate additive compositions which may be used in fabric softening and dishwashing as well as laundry detergent compositions.
    Type: Grant
    Filed: February 6, 1996
    Date of Patent: August 12, 1997

The process includes mixing a porous carrier material, typically containing perfume, and an encapsulating material, typically a carbohydrate material, to form agglomerates or an extrudate which is then sized into particles for incorporation into a detergent product. The process may be employed to produce particulate additive compositions which may be used in fabric softening and dishwashing as well as laundry detergent compositions.

  • Patent number: 5486303
    Abstract: A process for preparing high density detergent agglomerates having a density of at least 650 g/l is provided. The process comprises the steps of: (a) charging a viscous surfactant paste into a mixer/densifier wherein the surfactant paste has a viscosity of from about 5,000 cps to about 100,000 cps and contains at least about 5% water; (b) adding from about 1% to about 70% of an anhydrous material into the surfactant paste just prior to entrance into the mixer/densifier to absorb at least a minor amount of the water from the surfactant paste; and (c) agglomerating the surfactant paste and the anhydrous material in the mixer/densifier so as to form detergent agglomerates having a density of at least about 650 g/l. The detergent agglomerates have high surfactant levels.
