Abstract
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.
Claims18
An oral care composition comprising:
- a. a gel network phase comprising at least about 14% fatty amphiphile fatty amphiphile and a secondary surfactant;
- b. from about 1% to about 8%, by weight of the composition, potassium nitrate;
- c. from about 2% to about 25%, by weight of the composition, 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 fluoride ion source provides a fluoride ion concentration from about 0.005% to about 2.0%, by weight of the composition;
- and wherein phase separation is not visually perceptible as determined by the phase separation method.

3 more elements
A method for making an oral care composition comprising the steps of:
- a. combining water and a fatty amphiphile;
- b. heating the water and the fatty amphiphile until the fatty amphiphile melts and a solution is formed;
- c. cooling the solution;
- d. adding a fluoride ion source and/or an abrasive and/or a peroxide;
- e. adding a secondary surfactant;
- f. mixing until the composition is substantially homogeneous;
- g. deaerating until the composition is substantially free of air;
- wherein a gel network is formed.
