Abstract: Oral care compositions containing a stannous salt and sodium tripolyphosphate are provided where stannous tripolyphosphate ionic intermediates comprise less than about 1% of the compositions. Tetrasodium pyrophosphate, a methylvinyl ether-maleic anhydride copolymer and/or a silica oral polishing agent may be added for further efficacy. In a single phase blend, the oral care composition may be effectively limited to comprise less than about 10% water. In a dual-phase blend, a mixture having the stannous salt in a first phase and the sodium tripolyphosphate in a second phase may be generated from a dual chamber storage tube (with each phase provided from a separate chamber) immediately prior to dental care usage.

Abstract: Disclosed herein is a dual component oral care composition comprising a first component comprising a solid composition comprising at least one whitening agent chosen from chloride isocyanurate and metal salts of hypochlorite; and a second component comprising an aqueous mouthwash composition comprising at least one effervescent acid. Further disclosed herein is a kit comprising the solid composition and the aqueous mouthwash composition, as well as methods of whitening teeth and/or producing antibacterial effects in the oral cavity comprising mixing the solid composition with the aqueous mouthwash composition until the solid composition disintegrates to create a mouthwash comprising hypochlorite; and contacting teeth with the mouthwash comprising hypochlorite.
