Oral care compositions containing a gel network phase

Silica particles having a d50 median particle size from 8 to 20 μm, a sphericity factor (S) of at least 0.9, a BET surface area from 0.1 to 8 m/g, a total mercury intrusion pore volume from 0.35 to 0.8 cc/g, and a loss on ignition from 3 to 7 wt. %, are disclosed, as well as methods for making these silica particles, and dentifrice compositions containing the silica particles.

Spherical stannous compatible silica particles for reduced RDA

Silica particles having a BET surface area from 0.1 to 7 m/g, a pack density from 35 to 55 lb/ft, an Einlehner abrasion value from 8 to 25 mg lost/100,000 revolutions, a total mercury intrusion pore volume from 0.7 to 1.2 cc/g, and a stannous compatibility from 70 to 99%, are disclosed, as well as methods for making these silica particles.

Stannous compatible silica

An oral care composition containing a gel phase, an abrasive, and a fluoride source. The gel network phase contains a cold dispersible fatty amphiphile and phase separation is not visually perceptible in the oral care composition.

Oral care compositions with silica particles and stannous fluoride with an improved tin compatibility are disclosed. Oral care compositions with silica particles and stannous fluoride with a low level of an additional tin compound are disclosed. Oral care compositions with substantially spherical silica particles are disclosed.

Oral care compositions with improved tin compatability

Dentifrice containing silica particles having a d50 median particle size from 4 to 25 &#x3bc;m, a BET surface area of less than 10 m/g, and a total mercury intrusion pore volume from 0.2 to 1.5 cc/g, are disclosed.

Dentifrice formulations having spherical stannous compatible silica particles for reduced RDA

An oral care composition containing at least 4% fatty amphiphile and from about 0.4% to about 5%, by weight of the composition, total flavor components. The flavor components contain at least 14%, by weight of the flavor components, of one or more high displaying flavor components.

Oral care compositions with an effective flavor display

An oral care composition containing a gel phase, potassium nitrate, a peroxide source, an abrasive, and a fluoride source. Phase separation is not visually perceptible in the oral care composition.

Oral care compositions containing potassium nitrate and peroxide

An oral care composition containing a gel phase, potassium nitrate, an abrasive, and a fluoride source. The gel network phase contains a cold dispersible fatty amphiphile and phase separation is not visually perceptible in the oral care composition.

Oral care compositions containing a gel network phase and potassium nitrate

A dentifrice composition containing an abrasive and a stannous ion source. The abrasive can contain precipitated silica particles where the extractable stannous ions after 30 days at 40&#xb0; C. is greater than about 75% of the initial extractable stannous ion concentration.

Dentifice compositions containing stannous compatible silica particles

An oral care composition containing a gel network phase, potassium nitrate, an abrasive and a fluoride ion source. The gel network phase contains a fatty amphiphile and a secondary surfactant. The oral care composition contains at least about 12% fatty amphiphile and phase separation is not visually perceptible.
