Publication number: 20060263236Abstract: Air freshener products and methods for freshening air are disclosed. In some embodiments, the air freshening product may include a container for storing an air freshening composition that may contain a perfume composition or may contain a perfume composition in conjunction with a malodor counteractant. The container may contain a propellant such as a compressed gas, and a dispenser; and the air freshening composition. The method of freshening air, in certain embodiments, delivers a consistent perfume release profile. If malodor counteractants are used, the method may also provide a reduction in malodors.Type: ApplicationFiled: July 25, 2006Publication date: November 23, 2006Inventors: Ricky Woo, Robert Dykstra, Carl Kaiser, Heather Schaeffer, Steven Diersing, Joshua Joseph, Zaiyou Liu

Publication number: 20050148544Abstract: A stable composition for removing unwanted molecules from a surface comprises functionally-available cyclodextrin, cyclodextrin-compatible surfactant, and cyclodextrin-incompatible surfactant. The compositions are suitable for capturing unwanted molecules from inanimate surfaces, including fabrics, including carpets, and hard surfaces including countertops, dishes, floors, garbage cans, ceilings, walls, carpet padding, air filters, and the like, and from animate surfaces, including skin, hair, and the like. The compositions can further comprise other cyclodextrin-compatible and -incompatible materials and other optional ingredients.Type: ApplicationFiled: March 8, 2005Publication date: July 7, 2005Inventors: Hirotaka Uchiyama, Ricky Woo, Dean DuVal, Steven Reece

Patent number: 5612308Abstract: Detergent compositions comprising a surfactant system that is either (1) a mixture nonionic and zwitterionic detergent surfactants; (2) a mixture of nonionic and amphoteric (non-zwitterionic) detergent surfactants; or (3) short chain nonionic detergent surfactant, the nonionic detergent surfactants preferably being short chain and/or having peaked distribution; optional hydrophobic cleaning solvent; and polycarboxylate, especially dicarboxylate, detergent builder provide superior cleaning of all of the soils commonly found in the bathroom. The compositions have a pH of from about 1 to about 5.5, preferably from about 2 to about 4 when the dicarboxylate builder is used. The compositions are in the form of aqueous liquids. Short chain peaked distribution nonionic detergent surfactants provide surprisingly superior sudsing characteristics.Type: GrantFiled: June 6, 1995Date of Patent: March 18, 1997Assignee: The Procter & Gamble CompanyInventors: Ricky A. Woo, Michel J. Carrie, William A. Cilley, Ronald A. Masters, Daniel W. Michael, Eddy Vos

Patent number: 5607913Abstract: Detergent compositions comprising a surfactant system that is either (1) a mixture of zwitterionic detergent surfactant and/or amphoteric (non-zwitterionic) detergent surfactant with nonionic detergent surfactant; or (2) short chain nonionic detergent surfactant; a suds reducing amount of a suds controlling alkoxylated material of the formula: C.sub.n (PO).sub.x (EO).sub.y (PO).sub.z in which C.sub.n is a hydrocarbon group containing n carbon atoms, n is a number from about 6 to about 12, x is a number from about 1 to about 6, y is a number from about 4 to about 15, and z is a number from about 4 to about 25; optional, but preferred, hydrophobic cleaning solvent; and polycarboxylate, especially dicarboxylate, detergent builder, provide superior cleaning of all of the soils commonly found in the bathroom while maintaining a desirable low suds profile and good rinsing properties. The compositions have a pH of from about 1 to about 5.5, preferably from about 2 to about 4 when the dicarboxylate builder is used.Type: GrantFiled: November 21, 1994Date of Patent: March 4, 1997Assignee: The Procter & Gamble CompanyInventors: Ricky A. Woo, James E. Gray

Patent number: 5562850Abstract: Toilet bowl detergent compositions, preferably blocks of the "in-tank" or "rim-block" types, contain a cleaning system comprising: detergent surfactant of the amphoteric type, preferably zwitterionic, more preferably one that contains a carboxylate group and a cationic group, and even more preferably a fatty acid amidoalkylene betainc, and polycarboxylate chelating agent, preferably, citric acid, or similar polycarboxylic acid, are combined with some means of creating the desired concentration of the cleaning system in the toilet bowl water, preferably by means of blocks with a dissolution retarding system, preferably with the dissolution retarding system comprising a combination of water soluble cellulosic polymer, more preferably hydroxyethyl cellulose or hydroxypropyl cellulose and, polyethylene glycol containing polymer, any perfume present being selected to be mostly hydrophobic. The compositions have a pH, in use, of from about 4 to about 9 and the blocks are preferably extremely homogeneous.Type: GrantFiled: July 26, 1995Date of Patent: October 8, 1996Assignee: The Procter & Gamble CompanyInventors: Ricky A. Woo, Daniel S. Cobb, Jeffrey L. Flora

Patent number: 4456626Abstract: A shortening for preparing moist, light and tender cakes is disclosed. The shortening comprises a fat or oil and an emulsifier which consists essentially of from about 10% to about 20% of propylene glycol mono-fatty acid esters and from about 3% to about 20% of hydrophilic polyglycerol ester (percentages are based on the weight in the shortening). The ratio of polyglycerol ester to propylene glycol monoester is about from about 2:1 to 7:1. This shortening system can be used in preparing baking mixes. Surprisingly, even in an add-oil preparation the cake is moist yet light and tender.Type: GrantFiled: October 25, 1982Date of Patent: June 26, 1984Assignee: The Procter & Gamble CompanyInventors: Kenneth W.
