COMPOSITIONS FOR ORAL CARE, CONTAINING ZINC COMPLEX WITH AMINO ACID AND HALOGENIDE Russian patent published in 2017 - IPC A61K8/27 A61K8/44 A61K8/20 A61Q11/00 

FIELD: pharmacology.

SUBSTANCE: oral care composition in the form of a toothpaste containing a zinc-lysine-HCl complex, as well as zinc-lysine-HCl complex application for preparation of such a composition in the form of a toothpaste and a method for treatment or reduction of tooth enamel erosion, caries and cavities formation inhibition and/or dentin sensitivity reduction, comprising application the above-mentioned toothpaste composition to the teeth. A composition for reduction of tooth enamel acid erosion, caries and cavities formation inhibition, and/or reduction of the increased dentin sensitivity, comprising a zinc-lysine-HCl complex that has the chemical structure of [Zn(C₆H₁₄N₂O₂)₂Cl]⁺Cl^- and can either be in a solution as a cation ([Zn(C₆H₁₄N₂O₂)₂Cl]⁺) and chloride anion, or in the form of a solid salt.

EFFECT: application of the zinc-lysine-HCl complex provides an effective concentration of zinc ions for the teeth enamel and formation of a deposit that can close the dentinal tubules during composition application, which is achieved by high solubility of the zinc-lysine-HCl complex in combination with the zinc compound precipitation when diluted with water.
