Dicalcium phosphate dihydrate having improved stability and a method for preparing it |
| abstract |
Dicalcium phosphate dihydrate containing a sufficient amount of trimagnesium phosphate and/or tetrasodium pyrophosphate to inhibit spontaneous hydrolysis and/or decomposition of the dicalcium phosphate dihydrate is widely used as a dental polishing agent with and without added fluoride. Now it has been found that dicalcium phosphate dihydrate containing a sufficient amount of pyrophosphate to provide hydrolytic stability to the dicalcium phosphate can have improved fluoride stability when about 0.1 weight percent to about 5 weight percent of trimagnesium phosphate, and about 0.1 weight percent to about 3 weight percent of at least one pharmaceutically acceptable condensed phosphate salt is added to the formulation. In the preferred embodiment less than 2 percent sodium tripolyphosphate provides satisfactory results. |
