A phosphate-containing synthetic hydrotalcite of the following empirical formula: xMgO.Al2O3.yPO4.zH2O wherein, x, y and z are integers indicating the number of moles present of MgO, PO4 and H2O, respectively. The phosphate-containing hydrotalcite being prepared by the addition of sufficient phosphoric acid to the reaction mixture to liberate carbon dioxide. The phosphate-containing hydrotalcite improves the flame retardant characteristics by providing char promotion to the system.
