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

Described herein are oral care compositions comprising metal silicates (e.g. sodium silicate); along with methods of making and using same.

Oral care composition

This application provides, among other things, novel aqueous oral care compositions useful for combining and delivering poorly compatible ingredients, in particular, chlorhexidine and polyphosphate salts, by formulating the composition with a surfactant.

Oral care compositions

Described herein are oral care compositions comprising metal silicates (e.g. potassium silicate); along with methods of making and using same.

An oral care composition and methods for whitening teeth are disclosed herein. The whitening composition may include an orally acceptable vehicle and one or more abrasives. The one or more abrasives may include at least one plant-based abrasive. The method for whitening teeth may include contacting the oral care composition with surfaces of the teeth at least twice a day for at least nine days.

Oral care compositions including plant-based abrasives and methods for the same

Methods for preparing high loading core shell silica (CSS) particles, or CSS particles having a relatively greater amount of surface active silicate groups than CSS particles prepared according to conventional methods is provided. The method may include contacting silica particles with a base having a first metal ion to produce core shell silica particles. Each of the core shell silica particles may include a silica core and a silicate of the first metal ion etched on a surface of the silica core. The method may also include contacting each of the core shell silica particles having the silicate of the first metal ion with an acidic aqueous solution including a metal salt having a second metal ion to produce core shell silica particles including the silica core and a silicate of the second metal ion on the surface of the silica core.
