Abstract: A mouthrinse containing chitosan or pharmaceutically acceptable acid addition salt thereof with fluoride ions, for use against erosive tooth demineralization, and kits containing chitosan or pharmaceutically acceptable acid addition salt thereof with fluoride ions, wherein one of the two active agents is comprised in a mouthrinse, are described. The mouthrinse may furthermore comprise dissolved tin, in particular stannous ions. Mouthrinses containing chitosan or pharmaceutically acceptable acid addition salt thereof with fluoride ions are tested in the treatment or prevention of erosive tooth demineralization caused by citric acid.

Abstract: Described herein are stable aqueous stannous ion containing compositions and methods of preparing and using the same.

Abstract: An oral care composition is provided. The composition comprises (a) a first component comprising an amine fluoride; and (b) a second component comprising an acidic polymer; wherein the amine fluoride and acidic polymer have respective first and second reactive groups which are arranged to react together to form a cross-linked copolymer of the amine fluoride and acidic polymer when the composition is applied to an oral cavity.

Abstract: The present application provides a packaged aqueous oral care composition comprising a container and a composition wherein the composition comprises at least one water-soluble source of Sn2+ ions and the container comprises an inner surface being at least partially formed from a linear polymer, wherein the linear polymer is a homopolymer or a copolymer of monomers having the structure: wherein R1 and R2 are the same or different and are independently selected from a hydrogen atom, an alkyl group, an alkenyl group, a halogen atom and a nitrile group.

Abstract: Disclosed herein are processes for oxidising Sn2+ dissolved in an aqueous solution to stannic compounds using NO2 and optionally O2 as oxidants, wherein the aqueous solution is kept at a pH in the range of 0 to 7, wherein a salt Sn2+(Xn?)2/n and the oxidants are used according to the reaction scheme a Sn2+(Xn?)2/n +b O2+c NO2??stannic compounds in which scheme a, b and c are mole numbers; with the proviso that when b is essentially zero, then the aqueous solution is essentially free of Cl?, HSO4? and SO42?.

Abstract: An oral care composition comprising a) an aqueous phase; b) stannous ions solvated in the aqueous phase; c) nitrates solvated in the aqueous phase; wherein the total content of said nitrates is such that the molar amount of nitrogen in the aqueous phase, measurable as nitrate, is less than 2 times the molar amount of solvated stannous ions; and d) a flavor substance, which is preferably solvated, dispersed or emulgated in the aqueous phase. Disclosed are also containers containing the composition; and processes and uses for stabilizing stannous ions against oxidation, using nitrates.
