  • Patent number: 5112520
    Abstract: A detergent composition and method may have the soil anti-redeposition properties significantly and unexpectedly improved by incorporating into the detergent composition an effective amount of an anti-redeposition agent. The anti-redeposition agent is a modified vegetable protein material such as a soy protein isolate which has been modified with an ionic monomer. Ionic monomers which have been found to be especially effective at improving the anti-redeposition properties of washing detergent compositions are cationic epoxide monomers, cationic acrylate monomers and cationic chlorohydrin monomers. Anionic or carboxylated soy protein derivatives have also been shown to be effective anti-redeposition agents.

  • Patent number: 5104567
    Abstract: An environmentally acceptable cleaning liquid for use in the graphic industry consisting of 90-99% of a vegetable oil, in particular soy oil, and 1-10% of a surfactant emulsifier. The liquid is suitable for removing ink from printing machines where it is capable of replacing the traditional cleaning liquids based on petroleum spirit and aromatic solvents. As the liquid does not contain any health hazardous components it is completely safe to work with, and due to its bio-decomposable character it is disposable without problems. Because of its excellent penetration properties the liquid is also suitable for cleaning off machine parts which otherwise are difficult to clean, e.g. rubber sheets.

  • Patent number: 5064553
    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 1.35 to 1.40 g/cc which roughly corresponds to the density of the liquid phase. Stearic acid or other fatty acid or salt further improves physical stability.
