  • Patent number: 6420333
    Abstract: A process for encapsulating a benefit agent and/or colorant for personal care or detergent compositions, the process comprising immersing an emulsion or a dispersion containing the benefit agent and/or colorant into an aqueous curing solution containing a high HLB surfactant and/or a super-wetting agent. The preferred process further includes increasing the density of the droplets, to allow for easier penetration into the curing solution.

  • Publication number: 20020083615
    Abstract: A new dispenser for laundry products, particularly for fabric softener products to be used in the dryer. The dispenser comprises a hollow ball having a plurality of product dispensing openings and a further product ingress opening for placing product in the ball. A measuring cup to hold product is accessed from the product ingress opening. In accordance with one preferred embodiment, the measuring cup includes only a single opening in its side wall for releasing product from the cup and into the hollow sphere. One or more closures are associated with the dispenser. After travelling through the small hole in the cup, the product is dispensed to the exterior of the hollow ball through the product dispensing openings and thus onto product. The hollow ball is preferably a manually squeezable plastic such as polyurethane. In another embodiment, the cup includes more than the single hole in the cup walls.

  • Publication number: 20020086806
    Abstract: A new pouch for laundry products and the combination of pouch and laundry product. The pouch includes a tearing notch or a length of weakness, which may comprise a tear tape, permitting manual opening of the pouch prior to tossing the pouch into the washing machine. By tearing open the pouch it is possible to direct liquid or gelled detergent onto clothes for pretreating stains. The remainder of the product, in a second chamber, e.g. liquid, gel or solid, eg, a powder, is retained in the pouch until release during wash. In this respect, it is preferred that at least part of the pouch is a water soluble film to promote release of product during washing in the washing machine and to minimize residue left from the pouch at the conclusion of the wash. The pouch of the invention preferably comprises at least two chambers, one of the chambers being openable by manual tearing along a tearing notch or a line of weakness.

  • Patent number: 5750489
    Abstract: The present invention relates to liquid detergent compositions comprising substantially linear, water soluble, highly salt-tolerant non-adsorbing, ionic polymers of MW 10,000 to 1,000,000 Daltons which, when added in defined minimum levels to structured heavy duty liquids, make the liquids highly shear thinning without decreasing pour viscosity of the composition or increasing it to a point where it is too thick. The compositions are also stable.
