Abstract
A calcium phosphate-based core-shell structured material, a method for preparing the same, and an oral care composition using the same are provided. The calcium phosphate-based core-shell structured material includes an amorphous calcium phosphate (ACP) core and a β-tricalcium phosphate (β-TCP) shell covering the core. The method includes a first sintering step and a second sintering step. The first sintering step is to sinter an ACP material at between 700° C. and 800° C. to obtain an α-TCP shell. The second sintering step allows the α-TCP shell to form into the β-TCP shell by sintering at between 800° C. and 900° C. The oral care composition includes a calcium phosphate mixture and an orally receivable carrier. The calcium phosphate mixture includes a powder of the calcium phosphate-based core-shell structured material and a tricalcium phosphate powder mixed in a weight ratio from 3:5 to 3:7.
