ABSTRACT OF THE DISCLOSURE A stable and clear aqueous solution of zinc salt useful as a mouthrinse and a gel dentifrice. In a preferred embodiment the aqueous solution comprises zinc chloride codissolved with a complexing agent of sodium gluconate, in a naturally derived anionic polymer of sodium carboxymethyl- cellulose. This solution is advantageous because it maintains clarity and chemical stability in temperatures of from about 4 to about 50°C and may be alcohol-free. The anionic polymer acts as a buffer to provide a solution with a pH in a desirable range of from about 5.7 to about 6.5, which limits astringency and tartness. JDC-181
