Patent number: 7235187Abstract: Reaction mixtures that include exothermic generating particles having a water soluble coating encasing a portion of the particles, a volatile component and, optionally an aqueous solution, and a buffer. The reaction mixtures are especially suited to generate heat in a controllable manner. In one such controlled reaction, the reaction components are mixed together and the mixture increases in temperature to a Set Temperature within a predetermined time, and the mixture remains at the Set Temperature for a longer period of time. In this manner, volatile components can be controllably released to the surrounding environment. The volatile components can be, for example, a perfume, a fragrance, an insect repellent, a fumigant, a disinfectant, a bactericide, an insecticide, a pesticide, a germicide, an acaricide, a sterilizer, a deodorizer, a fogging agent and mixtures of these. Apparatuses and methods that use these reaction mixtures are also disclosed.Type: GrantFiled: January 13, 2003Date of Patent: June 26, 2007Assignee: The Procter & Gamble CompanyInventors: Yu-jun Li, Mark Hsiang-Kuen Mao, Haruo Tamura

Patent number: 7129311Abstract: An organohydrosiloxane composition comprising: a) one or more organohydrosiloxane compounds, each having at least one [—HSiR—O—] unit, wherein R?C1–C18 linear, branched, or cyclic alkyl, C1–C18 linear, branched, or cyclic alkoxy, or substituted or unsubstituted aryl, and b) an antioxidant compound shown in Formula (1) ?wherein the antioxidant compound is a phenolic compound and is present in a concentration from about 1 ppm to about 5,000 ppm and wherein R1 through R5 can each independently be H, OH, C1–C18 linear, branched, or cyclic alkyl, C1–C18 linear, branched, or cyclic alkoxy or substituted or unsubstituted aryl. The compositions of present invention exhibit stability and significantly extend the shelf life of organohydrosiloxane products and allow greater flexibility in handling these products in chemical processes or semiconductor manufacturing. The resulting stabilization of siloxanes prevents the possibility of complete polymerization (i.e.Type: GrantFiled: September 18, 2003Date of Patent: October 31, 2006Assignee: Arch Specialty Chemicals, Inc.Inventors: Daniel J.

Patent number: RE41109Abstract: A composition of matter and the method of making that provides a low pH acidic composition that is useful for destroying microorganisms that are undesirable and useful for destroying or reducing melanomas on human skin. The composition and method include sulfuric acid combined with distilled water and ammonium sulfate under at least 15 psi pressure in a pressurized container, all of which is heated to approximately 800° F. or more for at least 3 hours. The final cooled mixture is stabilized with 10 percent of the original mixture. The resultant composition is useful for preserving food, such as fresh fish, and for skin treatment of melanoma and as bactericides, fungicides, or viricides.Type: GrantFiled: June 3, 2003Date of Patent: February 9, 2010Assignee: Phitex, L.L.L.P.Inventor: Barry W.
