Patent number: 6884765Abstract: A process for cleaning textile fabric without the need for conventional detergent systems comprising agitating the fabric in a composition comprising at least two immiscible liquids, for example, perchloroethylene or petroleum ether and water, having at least one liquid-liquid interface with an interfacial tension of at least 5 mN/m, preferably at least 10 mN/m, and where the concentration of the most polar liquid in the composition is from 10 to 90% by volume.Type: GrantFiled: May 18, 2001Date of Patent: April 26, 2005Assignee: Unilever Home & Personal Care USA division of Conopco, Inc.Inventor: Vijaya Milind Bargaje

Patent number: 6727218Abstract: The present invention relates to a cleaning composition comprising an immiscible liquid system having at least one liquid-liquid interface with an interfacial tension greater than 5 mN/m. The less polar solvent in the system has a carbon chain length of at least 4, or is a silicone with more than 3 SiO units. The composition furthermore comprises from 0.001-20% by weight of a benefit agent such as a fluorescer, a dye transfer inhibitor, a fabric softening agent or an anti redeposition agent. The compositions provide for an improved delivery and efficacy of the benefit agents in e.g. a fabric cleaning process.Type: GrantFiled: October 10, 2002Date of Patent: April 27, 2004Assignee: Unilever Home & Personal Care USA, division of Conopco, Inc.Inventors: Vijaya Milind Bargaje, Kavitha Dhandapani, Glyn Roberts

Patent number: 6706678Abstract: The invention relates to a cleaning composition comprising an immiscible liquid system having at least one liquid—liquid interface with an interfacial tension greater than 5 mN/m. The less polar solvent in the system has a carbon chain length of at least 4, preferably greater than 6, or is a silicone with more than 3 SiO units. Typical examples of suitable less polar solvents are hydrocarbons, fluoroethers, polydimethylsiloxanes and fatty acid methyl esters. The more polar liquid in the system is preferably water. The composition is particularly suitable for cleaning soiled fabric, especially to remove particulate soil therefrom.Type: GrantFiled: October 10, 2002Date of Patent: March 16, 2004Assignee: Unilever Home & Personal Care USA, division of Conopco, Inc.Inventors: Vijaya Milind Bargaje, Vidur Behal, Kavitha Dhandapani, Glyn Roberts

Publication number: 20030135934Abstract: The present invention relates to a washing machine in which a composition is used comprising at least one liquid-liquid interface, with an interfacial tension of at least 5 mN/m. The washing machine comprises a heatable wash drum, means for storing dispensing and mixing the liquids, means for introducing the liquids into the drum, and means for filtering, separating, distilling and condensing the wash liquor and vapours and recovering the solvents. Use of the machine enables discharge of waste water with only low levels of solvent, and facilities recovering of the solvents.Type: ApplicationFiled: November 19, 2002Publication date: July 24, 2003Applicant: Unilever Home & Personal Care USA, Division of Conopco, Inc.Inventors: Rahul Banerjee, Vijaya Milind Bargaje, Kavitha Dhandapani, Glyn Roberts
