  • Patent number: 8664173
    Abstract: The present invention is directed to a premoistened, disposable, cleaning substrate to improve dirt pick-up and to retard redeposition of the dirt back onto the cleaned leather surface. The said substrate is incorporated therein with a cleaning composition to improve cleaning and impart protection and/or preservation of the leather surface or article. The said substrate is further incorporated therein with UV absorbers to further protect the leather surface, improve appearance and durability. The impregnated substrate can be employed to clean leather surfaces such as furniture, clothing, shoes, belts, automobile upholstery and the like. In addition, a method of preserving a leather surface or article by contacting said surface with said substrate is disclosed.
    Type: Grant

  • Patent number: 8093199
    Abstract: The present invention is based in part on the discovery that impregnating a cleaning substrate with a nonionic, linear polymer unexpectedly improves the cleaning efficacy of the article and prevents redeposition of soil and dirt onto the cleaned hard or soft surface. The nonionic, linear polymer is, for example, polyacrylamide. In addition, a method of incorporation of a cleaning composition into said substrate is disclosed.

  • Patent number: 6972274
    Abstract: The present invention generally relates to a method and a composition useful in restoring the permeability of a porous underground petroleum containing formation. Restoring permeability to the formation enhances the injectivity thereby accelerating petroleum recovery. The method of the invention comprises treating said formation with a composition which comprises a combination of at least one nonionic compound, preferably an alkoxylated alcohol, with at least one cationic compound, preferably a quaternary ammonium compound, in an amount effective to improve the permeability of the formation. The composition may also optionally contain an alkyl glycoside.

  • Patent number: 6462014
    Abstract: The present invention generally relates to low foaming and/or defoaming cleaning formulations which, comprises a synergistic combination of one or more hydrotropic alkoxylated quaternary ammonium compounds and at least one nonionic surfactant based on branched alcohols. The nonionic surfactant may be selected from structures having 3 to 12 moles of ethoxylation, but preferably have an average of 3-6 moles of ethoxylation with either narrow or broad range distribution.
