  • Patent number: 5658867
    Abstract: Cleaning compositions comprise a builder material which has substantially improved performance and is significantly less expensive than previous builders. The builder material has improved performance in that it unexpectedly has a high calcium ion exchange capacity and rate, and is easy to handle, process and disperse in washing solutions. The cleaning compositions contain a builder material having at least one crystalline microstructure including a carbonate anion, calcium cation and at least one water-soluble cation, wherein the builder has a particle size diameter within selected ranges for optimal performance. The microstructure should have a sufficient number of anions and cations so as to be "balanced" or "neutral" in charge.

  • 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.
