Patent number: 7037883Abstract: A process of making a liquid laundry detergent composition comprising a polyanionic ammonium surfactant, the process comprising: forming the polyanionic ammonium surfactant by mixing a liquid carrier with: (a1) from about 0.03% to about 85%, by weight of the composition, of a conjugate acid of an anionic surfactant; and (a2) from about 10% to about 50%, based on the molar equivalent of the amount of the conjugate acid, of a polyamine; (a3) wherein the mixing of (a1) and (a2) is carried out in the substantial absence of bases other than the polyamine. Also included is a process wherein the monoanionic surfactant is formed along with the polyanionic ammonium surfactant, in which case a base other than the polyamine may be present but than the amount of such base should be no greater than the required stoichiometric amount of the base to form the monoanionic surfactant.Type: GrantFiled: September 17, 2003Date of Patent: May 2, 2006Assignee: Unilever Home & Personal Care USA Division of Conopco, Inc.Inventors: Feng-Lung Gordon Hsu, Yun Peng Zhu

Publication number: 20040232032Abstract: The present invention is directed to a device for dispensing a unit dose water-soluble pouch containing a laundry additive during the spin cycle of a washing machine process having a spinning wash drum. The device is attached to the vertical center post of a washing machine and holds a water-soluble pouch above the high water level. During the spin cycle, the spinning center post will create sufficient centrifugal force so that the water-soluble pouch is released from the device. The water-soluble pouch will then fall into the laundry where the water-soluble pouch will dissolve when rinse water fills the machine thereby releasing the laundry additive to treat the washed articles.Type: ApplicationFiled: May 21, 2003Publication date: November 25, 2004Applicant: Unilever Home & Personal Care USA, Division of Conopco, Inc.Inventors: Feng-Lung Gordon Hsu, Daniel Joseph Fox, Edward John Giblin, Ronald Frederick Vogel, Gary Hsu, Mohammad Hosseini-Nejad

Patent number: 6815409Abstract: Gel detergent compositions which pile-up on a surface, upon dispensing, to minimize the spreading of the gel to a substantially larger area. The gels that can pile up are less messy to use and provide better stain removal, since more detergent is concentrated on the desired area of fabric (e.g., the spot). The composition comprises from about 10% to about 35% of a surfactant, from about 0.1 to about 5% of a non-neutralized fatty acid; from about 50 to about 85% of water; with the total of anionic surfactants selected from soap, linear alkyl benzene sulfonic acid, primary and secondary alkyl sulfates being more than 50% of total surfactant level.Type: GrantFiled: September 20, 2002Date of Patent: November 9, 2004Assignee: Unilever Home & Personal Care USA division of Conopco, Inc.Inventors: Feng-Lung Gordon Hsu, Yun-Peng Zhu, Ronald Frederick Vogel, Agnes Boudou, Charles Ebert, Kwang H Lee

Publication number: 20040102345Abstract: A laundry detergent product produced by a spray-on process and method of laundering clothes is disclosed which relates to the inclusion of one or more wrinkle reducing ingredients in the laundry detergent product. The spray-on process produces a freely flowable powder or granular laundry products that incorporate effective amounts of hydrophilic wrinkle reducing ingredients. The benefits are delivered to the laundered item during the cleaning step and, therefore, reduces the need for further wrinkle reducing steps when the items are taken from the dryer or after hang drying.Type: ApplicationFiled: November 22, 2002Publication date: May 27, 2004Applicant: Unilever Home and Personal Care USA, Division of Conopco, Inc.Inventors: Michael Orchowski, Dennis Stephen Murphy, Feng-Lung Gordon Hsu, Daniel Joseph Fox, John Brockett, David Alan Binder
