Patent number: 6784146Abstract: The present invention is a deinking method and composition that uses at least 50% by weight based on the total weight of surfactants of non-ionic, C16 to C25 aliphatic, monohydric alcohol alkoxylates having 14 to 40 moles of ethylene oxide per mole of alcohol and 0 to 10 moles of propylene oxide per mole of alcohol. Using deinking compositions to deink wastepaper pulp wherein the surfactants primarily include the C16 to C18 aliphatic alcohol alkoxylates of the invention produces paper having excellent brightness and low effective residual ink concentrations. In addition, a low amount of sizing agents is used to produce paper having acceptable levels of water repellency.Type: GrantFiled: October 27, 2000Date of Patent: August 31, 2004Assignee: Kemira Chemicals, Inc.Inventors: Jing Luo, David D. Dreisbach, Michael Lease Hemenway

Patent number: 6759380Abstract: A built laundry detergent composition contains a combination of anionic, nonionic and cationic surfactants which includes a highly ethoxylated nonionic surfactant which is a C8-C16 alcohol ethoxylated with an average of from 20 to 50 ethylene oxide groups. The cationic surfactant may advantageously be an ethoxylated quaternary ammonium compound. The composition exhibits improved oily soil detergency.Type: GrantFiled: September 12, 2003Date of Patent: July 6, 2004Assignee: Unilever Home & Personal Care USA division of Conopco, Inc.Inventors: Amrat Paul Singh, David Christopher Thorley

Patent number: 6756351Abstract: Cleaning packets containing laundry detergents are comprised of a water-soluble container or a water-insoluble container comprising a compound of the formula (I) wherein R1 is a linear or branched alkyl radical having from 2 to 18 carbon atoms, R2 is hydrogen or a linear or branched alkyl radical having from 2 to 18 carbon atoms, R3 is hydrogen or methyl, R4 is a linear or branched, alkyl and/or alkenyl radical having from 1 to 22 carbon atoms and n is a number from 1 to 50, with the proviso that the sum of the carbon atoms in the radicals R1 and R2 is at least 6. The cleaning packets exhibit improved washing performance.Type: GrantFiled: October 17, 2002Date of Patent: June 29, 2004Assignee: Cognis Deutschland GmbH & Co. KGInventor: Manfred Weuthen

Patent number: 6753306Abstract: A germicide and disinfectant composition contains detergent and at least two enzymes adapted to cause lysis in glycoprotein in infectious agents. These germicidal and disinfectant compositions are used in conjunction with prepackaged wipes and kits that allows the user to remove liquid or dried contaminated material without coming into direct contact with the contaminated material.Type: GrantFiled: June 3, 2002Date of Patent: June 22, 2004Inventor: Joseph J. Simpson

Patent number: 6746997Abstract: A process for the preparation of mixed ethoxylated alkyl phenol/alkyl phenol ethoxy sulfate surfactants, such surfactants, and detergent formulations incorporating the same. The mixed surfactants are more tolerant of sodium carbonate, allowing greater amounts of sodium carbonate to be used so that the amount of surfactant can be reduced resulting in overall cost savings in the resultant laundry product.Type: GrantFiled: September 3, 2002Date of Patent: June 8, 2004Assignee: Church & Dwight Co., Inc.Inventors: Charles D. Carr, Archana Gupta
