Patent number: 8956652Abstract: Effervescent tablets, powders and granules are provided which may be dissolved in water to produce an effervescent rehydrating beverage. The effervescent tablet, powder and granule compositions of the invention deliver electrolytes and carbohydrates at levels that provide hypotonic, isotonic or slightly hypertonic solution when dissolved in water, with acceptable taste.Type: GrantFiled: September 15, 2005Date of Patent: February 17, 2015Assignee: Tower Laboratories, Ltd.Inventor: Allen H. Rau

Patent number: 8206686Abstract: This invention provides a tablet that effervesces and significantly warms the water that it is dissolved in. The effervescence acts to break up the tablet allowing an exothermic material to rapidly dissolve releasing its heat of solution. The invention is unique in that no organic acid is required to form a conventional effervescent couple.Type: GrantFiled: April 17, 2009Date of Patent: June 26, 2012Assignee: Tower Laboratories, Ltd.Inventor: Allen H. Rau

Patent number: 8192724Abstract: A water soluble, non-abrasive, effervescent, pharmaceutically acceptable, oral care tablet for use in the oral cavity. The tablet includes a carbon dioxide source, a acid source and a tablet forming material admixed to form a chewable tablet having less than 0.2% water. The carbonate to acid ratio ranges from about 2.33:1 to about 3.33:1, the percent by weight of tablet forming material ranges from about 10% to about 70% of the total tablet weight, and the pH of the tablet when dissolved in water to form a 1.0% by weight aqueous solution ranges from about 5.0 to about 7.0. Also included is a flavor imparting flavor agent in an amount sufficient to mask taste sensations derived from the carbon dioxide source, acid source and binder to provide an abrasive-free texture to the tongue in the oral cavity. Other additives are contemplated.Type: GrantFiled: November 2, 2005Date of Patent: June 5, 2012Assignee: Tower Laboratories, Ltd.Inventor: Allen H. Rau

Patent number: 8007842Abstract: A composition for providing aromatherapy, and in particular, symptomatic relief of nasal and sinus congestion is provided in unit dosage format. The composition includes a penetrating aromatic vapor whose release from a preparation of warm water is augmented by an effervescent component which reacts in the warm water to promote release of the aromatic fragrance, or sustained over time by tableting or gelatin encapsulation. As the fragrance is inhaled, symptomatic relief is obtained. The composition of matter may be rendered ingestible, so that the warm water containing the composition is consumed following inhalation. In preferred embodiments, the release of the penetrating aromatic fragrance persists over time.Type: GrantFiled: April 13, 2007Date of Patent: August 30, 2011Assignee: Tower Laboratories, Ltd.Inventor: Allen H Rau

Patent number: 6310014Abstract: Personal and household care compositions that deliver an audible crackling or popping sound during use. The sound is created by the release of pressurized carbon dioxide that has been encapsulated in a water-soluble structure. The carbon dioxide gas is released as the encapsulating material dissolves or when it is ruptured by mechanical action. The popping or crackling sound helps create consumer interest by signaling the presence and continued action of the product.Type: GrantFiled: October 5, 1999Date of Patent: October 30, 2001Assignee: Phyzz Inc.Inventor: Allen H. Rau

Patent number: 6218347Abstract: A non-soap cleansing bar of superior lathering, feel and aesthetic characteristics is prepared with a quaternary ammonium surfactant, an anionic surfactant, a waxy binder, a filler and water. The balance of components is maintained so that the mixture can be formed on conventional plodding equipment. Optional elements, such as fragrances, preservatives, colorants, emollients and the like can be added.Type: GrantFiled: March 7, 2000Date of Patent: April 17, 2001Assignee: The Andrew Jergens CompanyInventors: Allen H. Rau, Vincent J. Fischer, Gregory A. Freeman, Mary A. Schwartz

Patent number: 6121215Abstract: A foaming effervescent bath composition is comprised of an effervescent base together with an anhydrous surfactant. The effervescent base may be sodium carbonate and an organic acid, or similar variations. The base is selected so as to provide a composition which has a high dissolution rate, of at least 0.4 g/sec. The product is designed so as to have a low density, not greater than about 1.0 g/cc. Surfactants that exhibit a high viscosity in the presence of low concentrations of salt give particularly good foaming performance. Other agents, such as a colorant, fragrance, humectant, or emollient, may be added.Type: GrantFiled: August 27, 1999Date of Patent: September 19, 2000Assignee: PHYZZ, Inc.Inventor: Allen H. Rau

Patent number: 5756438Abstract: A non-soap cleansing bar is provided which exhibits excellent foaming or lathering characteristics, resistance to cracking on drying, and good textural or "feel" characteristics, which employs a surfactant, filler and waxy binder as essential components. Skin-treatment components, colorants, fragrances and the like may be added as optional components. The bar is produced by a tableting operation that involves melting the waxy binder to obtain excellent wear characteristics and feel.Type: GrantFiled: March 26, 1996Date of Patent: May 26, 1998Assignee: The Andrew Jergens CompanyInventors: Allen H.

Patent number: 5110603Abstract: A bath preparation comprises a composition which, when dissolved in water, generates carbon dioxide, the composition being physically bound together as a tablet, with a colloidal material. The effervescence produced by dissolving the tablet improves dispersion of the colloidal material, and maintaining said colloidal material in dispersed form in the water for a longer period of time. The colloidal material is selected so as to provide relief from skin irritation. An acid, carbonate salt, and a colloidal material such as colloidal oatmeal may be tableted to provide an effective, easily stored and handled product.Type: GrantFiled: January 31, 1991Date of Patent: May 5, 1992Assignees: Kao Corporation, The Andrew Jergens CompanyInventor: Allen H.
