  • Patent number: 5245512
    Abstract: A polarizable material that includes a nonisotropic solution useful for making electrical devices. In one embodiment, the polarizable material is comprised of commercially available solid bar soap, neat soap or a polymorphic solid solution and employed as the dielectric in a capacitor or an electrolyte in a supercapacitor. In another embodiment the nonisotropic solution is employed as an electrolyte in an electrochemical battery.
    Type: Grant

    Assignee: Colgate-Palmolive Company
    Inventor: Rhyta S. Rounds
  • Patent number: 5232621
    Abstract: Automatic dishwasher detergent composition is formulated as a linear viscoelastic, pseudoplastic, gel-like aqueous product of exceptionally good physical stability, low bottle residue, low cup leakage, and improved cleaning performance, Linear viscoelasticity and pseudoplastic behavior is attributed by incorporation of cross-linked high molecular weight polyacrylic acid type thickener. Potassium to sodium weight ratios of at least 1/1 minimize amount of undissolved solid particles to further contribute to stability and pourability. Control of incorporated air bubbles functions to provide the product with a bulk density of about 1.28 to 1.40 g/cc which roughly corresponds to the density of the liquid phase. Stearic acid or other fatty acid or salt further improve physical stability.
