Patent number: 8865192Abstract: The present invention relates to flavor oils including mint-, fruit- and spice-type flavors that are specially processed to substantially eliminate low-molecular weight sulfur compounds, in particular dimethyl sulfoxide (DMSO), which has been found to be the main precursor of malodorous species such as dimethyl sulfide and methyl mercaptan. These malodorous species are produced via oxidation-reduction reactions involving such sulfur-containing compounds present in flavor oils. A preferred processing method is an aqueous-washing process, which has advantages of being simple, inexpensive and easy to implement while importantly avoiding the problems of typical processes including non-selective removal of desirable components and subjecting the flavor oils to extreme conditions that may destroy other components and result in undesirable changes in flavor or odor character.Type: GrantFiled: July 5, 2007Date of Patent: October 21, 2014Assignee: The Procter & Gamble CoInventors: Robert Leslie Swaine, Jr., Marc Hester, Steve Hoke, Denise McClenathan, Niranjan Ramji, Gerhard Norbert Zehentbauer

Patent number: 8691190Abstract: The present invention is directed to improved sweetener compositions and oral care compositions, especially those in the form of a toothpaste or oral/dental rinse, comprising the same. The sweetener composition comprises a combination of saccharin, sucralose and a rebaudioside, or sweeteners of similar sucrose equivalence and type, preferably in a ratio of about 1:about 1: about 2. The sweetener composition of the invention was found to significantly improve the taste profile, long lasting freshness and clean feel of oral care compositions and to deliver an in-use sweetness that was more natural and pleasant than artificial sweeteners alone.Type: GrantFiled: September 29, 2011Date of Patent: April 8, 2014Assignee: The Procter & Gamble CompanyInventors: John Christian Haught, Eva Schneiderman, Lowell Alan Sanker, Robert Leslie Swaine, Jr.

Patent number: 8007771Abstract: The present invention relates to oral care compositions comprising stannous ions, a mint-type flavor oil, a protectant component that prevents generation of off odor and off taste in the composition, and orally acceptable carriers. The mint-type oils include peppermint, spearmint and corn mint. Suitable protectant components include copper salts and carbonyl compounds such as ascorbic acid; cis-jasmone; 2,5-dimethyl-4-hydroxy-3(2H)-furanone; 5-ethyl-3-hydroxy-4-methyl-2(5H)-furanone; vanillin; ethyl vanillin; anisaldehyde; 3,4-methylenedioxybenzaldehyde; 3,4-dimethoxybenzaldehyde; 4-hydroxybenzaldehyde; 2-methyoxybenzaldehyde; 4-methoxybenzaldehyde; benzaldehyde; cinnamaldehyde (3-phenyl-2-propenal); hexyl cinnamaldehyde; ?-methyl cinnamaldehyde; ortho-methoxy cinnamaldehyde; ?-amyl cinnamaldehyde; and combinations thereof. The oral care composition may be a dentifrice.Type: GrantFiled: July 5, 2007Date of Patent: August 30, 2011Assignee: The Procter & Gamble CompanyInventors: Niranjan Ramji, Marc Hester, Steve Hoke, Robert Leslie Swaine, Jr., Gerhard Norbert Zehentbauer

Patent number: 7214400Abstract: Disclosed are flavor enhancing oils comprising at least one edible liquid oil and at least one water soluble flavor enhancer. The water soluble flavor enhancer is uniformly dispersed throughout the edible liquid oil. Delivery of water soluble flavor enhancers via a stable fat or oil base allows higher temperatures to be obtained during cooking, leading to the formation of enhanced flavors.Type: GrantFiled: April 25, 2000Date of Patent: May 8, 2007Assignee: Smucker Fruit Processing CompanyInventors: David Vincent Zyzak, Robert Leslie Swaine, Jr.
