Abstract
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.
Claims17
An oral care composition comprising:
- a. a gel network phase comprising a cold dispersible fatty amphiphile;
- b. potassium nitrate;
- c. an abrasive;
- and
- d. a fluoride ion source selected from the group consisting of stannous fluoride, sodium fluoride, potassium fluoride, amine fluoride, sodium monofluorophosphate, indium fluoride, amine fluoride, and combinations thereof;
- wherein the oral care composition comprises from about 3% to about 17% fatty amphiphile;
- wherein phase separation is not visually perceptible as determined by the phase separation method.
4 more elements
An oral care composition comprising:
- a. a gel network phase comprising a cold dispersible fatty amphiphile;
- b. from about 0.01% to about 3% thickening material selected from the group consisting of carboxyvinyl polymers, carrageenan, hydroxyethyl cellulose, water soluble salts of cellulose ethers, gum karaya, xanthan gum, gum arabic, gum tragacanth, magnesium aluminum silicate, finely divided silica, and combinations thereof;
- c. potassium nitrate;
- d. an abrasive;
- and
- e. a fluoride ion source selected from the group consisting of stannous fluoride, sodium fluoride, potassium fluoride, amine fluoride, sodium monofluorophosphate, indium fluoride, amine fluorides, and combinations thereof;
- wherein the oral care composition comprises less than about 10% fatty amphiphile;
- and
- wherein phase separation is not visually perceptible as determined by the phase separation method.
6 more elements
A method for making an oral care composition comprising the steps of:
- a. combining water and a cold dispersible fatty amphiphile;
- b. adding a fluoride ion source and/or an abrasive and/or potassium nitrate;
- c. adding a secondary surfactant;
- d. mixing until the composition is substantially homogeneous;
- e. deaerating until the composition is substantially free of air;
- wherein a gel network is formed and wherein the composition is not heated above 30° C.
