  • Patent number: 7159834
    Abstract: A stress-release mold is described for casting thermosetting compositions especially compositions designed for consumer use. At least one wall of the mold includes a stress-releasing-element characterized by having a more flexible region or regions than the remaining wall or walls of the mold and wherein the stress-releasing-element includes a region of lower curvature at least partially surrounded by a region of higher curvature. The stress-release mold greatly reduces or eliminates surface defects caused by shrinkage of thermosetting compositions as they cools. A system is also described that includes the inventive mold containing a thermosetting composition wherein the mold also serves as all or part of the package for the composition.

  • Patent number: 5981451
    Abstract: Novel compositions are prepared in a non-molten process. In particular, compositions comprise optional fillers with both soap and high levels of synthetic surfactants. When high levels of soap and surfactant are normally used in such process, there is a significant "grittiness" problem. Pre-processing the surfactant containing chip (e.g., "DEFI" chip) has been unexpectedly found to remedy this problem.

  • Patent number: 5900395
    Abstract: A solid detergent composition useful for machine dishwashing is described. The product contains a first layer having an oxygen bleach system, a buffering system, a builder, and an enzyme. The first layer dissolves to deliver a pH of about 8.5 to about 11 in the wash water. A second layer includes an effective amount of an acidity agent and a continuous medium having a melting point in the range of from about 35.degree. C. to about 50.degree. C. The material may be a paraffin wax, a natural wax, a polyvinyl ether, fatty acids and mixtures thereof. The second layer dissolves in wash water to deliver a pH of from about 6.5 to about 9. The release order of the functional ingredients allows for a high level of peracid species generation in the initial wash stages followed by optimum bleaching throughout the wash.
