    摘要: An electrical device such as an electric toothbrush that comprises a handle and a head portion. The head portion comprises a bristle bearing portion and an optional neck portion. The handle includes a housing having a housing exterior. First and second conductive contacts are located on the exterior of the housing. The first and second conductive contacts form part of a high impedance touch sensitive circuit configured to operate a motor to drive the bristle bearing portion when the handle is gripped by a user.

    摘要: A dentifrice for inhibiting calculus formation, comprising sodium bicarbonate, one or more alkali metal pyrophosphate salts, a soluble fluoride ion source and other adjuvants, in admixture with a buffering agent selected from among an alkali metal orthophosphate, o-phosphoric acid, an alkali metal glycerophosphate, tri(hydroxymethyl)aminomethane, tartaric acid or citric acid. The buffering agent is incorporated in the dentifrice in an amount of from about 0.1 to 2.5% by weight, sufficient to buffer the pH of the dentifrice to a value within the range of from about pH 8.2 to 8.9. The thus buffered dentifrice is subject to decreased risk of irritation of the oral mucosa or desquamation, as compared with dentifrices excluding such a buffering agent.

    摘要: This invention provides a single-phase aqueous solution of a zinc-polyamine complex which is stable and has a clear transparency. The aqueous solution can be incorporated as a component of an oral care product such as a mouthwash or toothpaste. The zinc-polyamine complex enhances the control of oral malodor, plaque, calculus and gingivitis in dental applications, and decreases the astringency and metallic taste which is characteristic of zinc ions in an oral cavity.
