1. A method for making an oral care composition comprising the steps of:
a. combining water and a cold dispersible fatty amphiphile, wherein the cold dispersible fatty amphiphile comprises:
(i) about 40%, by weight of the cold dispersible fatty amphiphile, of cetyl alcohol;
(ii) about 40%, by weight of the cold dispersible fatty amphiphile, of stearyl alcohol;
(iii) about 10%, by weight of the cold dispersible fatty amphiphile, of an anionic surfactant; and
(iv) about 10%, by weight of the cold dispersible fatty amphiphile, of a sodium acrylate/sodium acryloyl dimethyl taurate co-polymer;
b. adding a fluoride ion source, an abrasive, a metal salt, a peroxide source, or combinations thereof;
c. adding a secondary surfactant;
d. mixing until the composition is homogeneous; and
e. deaerating until the composition is free of air;
wherein a gel network is formed and the composition is not heated above 30° C. during any portion of the method.
