  • Publication number: 20120189986
    Abstract: A method of cleaning teeth by providing a device for generating a chemical agent in situ on an as-needed basis via the application of an electrical potential across a pair of conductors in communication with an electrolyte. The chemical agents may include ozone, hydrogen peroxide, peroxide, chlorine and/or hypochlorite. The device may include a voltage source and a first set of electrodes for applying an electrical potential to the electrolyte. The device may also include a second set of electrodes disposed about an anode of the first set of electrodes. The first and second sets of anodes cooperate to produce ions, peroxides, ozone and/or other chemical agents via the application of electrical potential to the electrolyte.

  • Patent number: 8156602
    Abstract: A device for generating a chemical agent in situ on an as-needed basis via the application of an electrical potential across a pair of conductors in communication with an electrolyte. The device may be a toothbrush that generates chemical agents in a user's mouth by applying an electrical potential to an electrolyte such as saliva and/or a dentifrice located therein. The chemical agents may include ozone, hydrogen peroxide, peroxide, chlorine and/or hypochlorite. The toothbrush may include a voltage source and a first set of electrodes for applying an electrical potential to the electrolyte. The toothbrush may also include a second set of electrodes disposed about an anode of the first set of electrodes. The first and second sets of anodes cooperate to produce ions, peroxides, ozone and/or other chemical agents via the application of electrical potential to the electrolyte.

  • Publication number: 20120077146
    Abstract: An oral care instrument includes at least one oral care agent. In one embodiment, the oral care agent can be provided on one or more surfaces of the oral care instrument or included within cavities within the head or in one or more surfaces of a head. In other embodiment, the oral care agent can be provided in or on a thin slab subsequently bonded onto a surface, or applied as a stable coating. The oral care instrument can also be provided with a wear indicator. The oral care agents can be released during one use, during multiple uses, or throughout the life of the instrument. Water, oral secretions and/or chemicals within the mouth can activate the oral care agents.

  • Publication number: 20120045493
    Abstract: A water soluble cosmetic or pharmaceutical or pharmaceutical actives in an electrolyte solution which, when impregnated with one or more retentive fillers (such as, for example, silica or hydrophobically modified silica, lamellar filler, crosspolymer, cellulosic, resins, or silicone elastomers) can form stable solid compositions with structurants. Such solid compositions do not require a higher buffer pH or leave residues upon application to the skin. Solid compositions according to the present invention are suitable for cosmetic and pharmaceutical purposes such as antiperspirants, deodorants, lip products, and other topical applications.
