Patent number: 7815960Abstract: Green tea formulations and methods for the preparation thereof are shown and described. Generally speaking, the method of preparation includes the mixing of fresh tea leaves in an amount of cold water, followed by pulverization of the leaves to release their intracellular material from the cells of the green tea leaves into the water and form an aqueous extract component. The remaining cellular material forms a leaf residue component which is removed from the mixture. Once the leaf residue is removed, the aqueous extract component is collected and may be dried or further processed to produce a final tea extract that has good natural color, robust natural flavor, and pleasant organoleptic properties, which also is high in polyphenol content, and may be used for various purposes such as the creation of a green tea beverage.Type: GrantFiled: June 18, 2007Date of Patent: October 19, 2010Inventors: Danyi Quan, Wade W. Xiong

Patent number: 6730318Abstract: The adhesive capability of matrix-type transdermal devices for the delivery of drugs, cosmetics, emollients and the like is altered by incorporating into the pressure-sensitive adhesive an effective amount of a polydiorganosiloxane polymer fluid adhesion adjusting agent. The properties of the pressure-sensitive adhesive are modified to enable a matrix-type patch to adhere temporarily to the skin for a period sufficient to accomplish its desired delivery purpose and then be removed without causing skin damage or irritation and without leaving substantial adhesive residue on the skin. Polydimethylsiloxanes (dimethicones) are preferred adhesion adjusting agents and acrylic-based polymers are preferred pressure-sensitive adhesives. Matrix-type patches containing anti-wrinkle agents formulated with dimethicones in the adhesive for application to areas on the face and particularly around the eyes are especially useful.Type: GrantFiled: August 8, 2001Date of Patent: May 4, 2004Assignee: Watson Pharmaceuticals, Inc.Inventors: Danyi Quan, Srinivasan Venkateshwaran, Charles D.

Patent number: 6727401Abstract: A device for treating antifungal infections of toenails and fingernails is made up of an occlusive backing layer and a pressure sensitive adhesive matrix layer in which is uniformly dispersed an effective amount of an antifungal agent and, optionally, a chemical enhancer. The matrix layer has a first surface adhering to the backing layer and a second surface adapted to be in diffusional contact with the infected nail and surrounding skin area. The device is configured, when applied, to cover and adhere to the nail and surrounding skin areas for an extended period of time without causing irritation to the skin or inhibiting normal physical activity while providing a continuous delivery of antifungal agent to the infected area.Type: GrantFiled: February 12, 1998Date of Patent: April 27, 2004Assignee: Watson Pharmaceuticals, Inc.Inventors: Srinivasan Venkateshwaran, Danyi Quan

Patent number: 6299925Abstract: A solid state water soluble formulation in granular or tablet form is provided. The formulation is a natural products formulation containing a green tea plant extract in combination with other ingredients which create an effervescent liquid composition upon dispensing the formulation in a liquid. The liquid form of administration, as well as the effervescent properties of the dissolved formulation increase bioavailability of the advantageous components of the green tea plants such as Polyphenols, by increasing absorption speed and amount in the human body. The formulation may include additional components such as, other plant extracts, vitamins, ionic minerals, and other substances purported to be of a health benefit.Type: GrantFiled: June 29, 1999Date of Patent: October 9, 2001Assignee: XEL Herbaceuticals, Inc.Inventors: Weihong Xiong, Danyi Quan, Dinesh C.

Patent number: 6180133Abstract: An anti-wrinkle skin treating composition comprises a pressure sensitive matrix patch having dissolved in the adhesive a mixture of antioxidants in the form of a Vitamins C ester and Vitamin E. Also preferably dissolved in the adhesive are glycerine and a polydiorganosiloxane adhesion-adjusting agent. Optionally dissolved in the adhesive is also one or more members selected from the group consisting of moisturizing agents, skin collagen synthesis promoting agents and exfoliating agents. When applied to a wrinkled skin area the composition acts to diminish fine wrinkles and improves the overall thickness, elasticity, firmness and smoothness of the skin. The modified adhesive properties of the patch are sufficient to maintain the patch in place on the skin for the recommended treatment period while allowing the patch to be readily removed without causing skin irritation or leaving adhesive residue on the skin.Type: GrantFiled: November 24, 1998Date of Patent: January 30, 2001Assignee: Watson Pharmaceuticals, Inc.Inventors: Danyi Quan, Srinivasan Venkateshwaran, Charles D.
