Abstract
A cationic compatible metal oxide and oral care compositions containing the metal oxide are disclosed. Preferably, the oral care compositions contain a cationic compatible metal oxide and a cationic ingredient, such as for example, a cationic antibacterial agent such as cetyl pyridinium chloride (“CPC”). The cationic compatible metal oxide, e.g. silica, comprise metal oxide particles having a substantially negative surface charge and a vitamin deposited onto or reacted with the surface of the metal oxide particles in an amount sufficient to provide a substantially positive surface charge on the metal oxide particle. Processes for making and using the vitamin modified metal oxide in oral care compositions are also disclosed.
