This application relates to novel aqueous oral care compositions useful for combining and delivering incompatible stannous fluoride or stannous chloride and potassium salts in a high-water composition, for example, to provide effective caries prevention, protection against dental erosion, and relief from dental hypersensitivity. The compositions comprise stannous fluoride or stannous chloride, nitric acid or a water-soluble nitrate salt, a water-soluble alkali metal polyphosphate and more than 10% water, by weight of the composition.

Oral care compositions and methods

An oral care composition including a hydrophobic phase and a hydrophilic phase is disclosed. The hydrophobic phase may include a source of hydrogen peroxide and an acyl donor, and the hydrophilic phase may include an enzyme having perhydrolytic activity that catalyzes the generation of peracetic acid between the source of hydrogen peroxide and the acyl donor.

Oral care compositions and methods for increasing the stability of the same

An electrolysis device may include a housing having a cavity that is configured to receive a precursor solution. The precursor solution may include chloride. An electrolysis circuit may be located in the cavity of the housing. The electrolysis circuit may include a power source, a first electrode and a second electrode electrically coupled to the power source, and a control circuit electrically coupled to the power source and the first and second electrodes. Upon the control circuit being activated while the precursor liquid operably couples the first and second electrodes together, the electrolysis circuit may be configured to generate a hypochlorite solution from the precursor solution.

Electrolysis device

Described herein are oral care compositions, comprising a peroxydone complex, a dispersant, and a polyvinylpyrrolidone copolymer structure-building agent.

Oral care compositions

A powered toothbrush includes a handle, a power source disposed in the handle, a head including a cavity disposed at a distal end of the handle, an electrically conducting element disposed in the cavity and electrically connected to the power source, and a movable cleaning element connected to the head and movable relative to the cavity. The movable cleaning element includes a tooth cleaning support member, a tooth cleaning element mounted on the support member, and a ferromagnetic member. Application of an electrical current to the electrically conducting element generates a magnetic field at the electrically conducting element. The magnetic field selectively at least one of attracts and repels the ferromagnetic member to move the movable cleaning element relative to the electrically conducting element.

Powered oral care implement

An electrolysis device may include: a housing comprising a container having an open end, the container configured to contain a liquid when the container is oriented in an upright position; and an electrolysis circuit comprising: a power source; a plurality of electrodes disposed within the container and electrically coupled to the power source; an orientation switch electrically coupled to the power source, coupled to the housing, and oriented to switch when the container is oriented in the upright position; and a control circuit electrically coupled to the power source, the electrodes, and the orientation switch, wherein the electrolysis circuit is configured to operate when the electrodes pass an electric current above a predetermined current threshold and the container is oriented in the upright position.

An oral care composition and methods for preparing the oral care composition are disclosed. The oral care composition may include a carrier and a structure-building agent. The carrier may be present in an amount of from about 0.01 wt % to about 99 wt %. The structure-building agent may include a polyvinyl capralactam-polyvinyl acetate-polyethylene glycol graft copolymers (PCA-PVA-PEG), and may be present in an amount of from about 0.01 wt % to about 60 wt %, based on a total weight of the oral care composition.

Oral care compositions and methods for the same

A two-phase oral care whitening composition including a hydrophobic phase and a hydrophilic phase, and methods for oral care whitening teeth with the same are provided. The hydrophobic phase may include a source of hydrogen peroxide and an acyl donor. The hydrophilic phase may include an enzyme that catalyzes the generation of peracetic acid between the source of hydrogen peroxide and the acyl donor. At least one of the hydrophobic phase and the hydrophilic phase may further include at least one surfactant.

Two-phase oral care whitening compositions

Disclosed herein are improved methods for the synthesis of stannous pyrophosphate, as well as improved methods for the manufacture of oral care compositions comprising stannous pyrophosphate.

Methods for synthesizing stannous pyrophosphate

A whitening composition and methods for whitening teeth and generating a whitening agent with the same are provided. The whitening composition may include an orally acceptable vehicle, a source of hydrogen peroxide that provides hydrogen peroxide, and a cyclic anhydride that generates a whitening agent with the hydrogen peroxided provided by the source of hydrogen peroxide. The whitening agent may be a peracid, such as a succinic peracid.

Oral care compositions including cyclic anhydrides

An oral care composition, including a non-aqueous dispersant and an amphiphilic copolymer structure-building agent.

Oral care composition

An oral care composition, including a non-aqueous dispersant and a fatty acid structure-building agent.
