Abstract
Described herein are oral care compositions comprising metal silicates (e.g. sodium silicate); along with methods of making and using same.
Claims17
An oral care composition comprising:
- a first metal silicate comprising sodium silicate;
- an orally acceptable carrier;
- a core shell silica particle comprising:
- a second metal silicate;
- and
- a silica particle comprising a core having a surface,
- wherein the surface of the silica core is etched with the second metal silicate, and the second metal silicate comprises a silicate of a monovalent, or multivalent metal ion, wherein the first metal silicate is not bound to the silica, and
- wherein the total amount of the first metal silicate and the second metal silicate is from about 0.5 to about 1.5 wt. %, and the oral care composition has a pH of 7.8 to 8.7.
