A mouthrinse preparation comprising between about 0.25% and about 0.65% hydrogen peroxide, between about 0.005% and about 0.1% zinc chloride, at least about 0.012% sodium citrate, at least about 0.03% sodium lauryl sulfate, at least about 0.006% citric acid and between about 2% and about 3.5% ethanol, said mouthrinse preparation remaining stable upon continuous exposure to a temperature of 37.degree. C. at atmospheric pressure for at least 30 days.
A mouthrinse preparation consisting of between about 0.25% and about 0.65% hydrogen peroxide, between about 0.005% and about 0.1% zinc chloride, at least about 0.012% sodium citrate, the sodium citrate content being such that the ratio of sodium citrate to zinc chloride is in the range of from about 1 to 1 to about 2 to 1, at least about 0.03% sodium lauryl sulfate, the sodium lauryl sulfate content being such that the ratio of sodium lauryl sulfate to zinc chloride is in the range of from about 2 to 1 to about 8 to 1, at least about 0.006% citric acid, between about 2% and about 3.5% ethanol, less than about 0.1% denaturing agent or combination of denaturing agents, between about 1.8% and about 9.0% glycerin, between about 0.022% and about 0.1% disodium EDTA, less than about 1.0% solubilizer, less than about 1.0% sweetening agent or combination of sweetening agents, and the balance of deionized water, said mouthrinse preparation having a shelf life of greater than about 2 years.
A mouthrinse preparation consisting essentially of between about 0.25% and about 0.65% hydrogen peroxide, between about 0.005% and about 0.1% zinc chloride, at least about 0.012% sodium citrate, the sodium citrate content being such that the ratio of sodium citrate to zinc chloride is in the range of from about 1 to 1 to about 2 to 1 on a weight percent basis, at least about 0.03% sodium lauryl sulfate, the sodium lauryl sulfate content being such that the ratio of sodium lauryl sulfate to zinc chloride is in the range of from about 2 to 1 to about 8 to 1 on a weight percent basis, at least about 0.006% citric acid, between about 2% and about 3.5% ethanol, less than about 0.1% denaturing agent or combination of denaturing agents, between about 1.8% and about 9.0% glycerin, between about 0.022% and about 0.1% disodium EDTA, less than about 1.0% solubilizer, less than about 1.0% sweetening agent or combination of sweetening agents, and the balance of deionized water, said mouthrinse preparation having a shelf life of greater than about 2 years.
A method for preparing a mouthrinse preparation comprising the steps of:
- providing an alcohol solution containing alcohol;
- preparing a zinc chloride solution by dissolving zinc chloride in deionized water and allowing the zinc chloride solution to cool;
- adding sodium lauryl sulfate, citric acid and sodium citrate to the zinc chloride solution, mixing the zinc chloride solution, and allowing the zinc chloride solution to cool;
- mixing the alcohol solution with the zinc chloride solution and allowing a resulting solution to cool;
- and
- adding a hydrogen peroxide solution to the resulting solution and mixing to provide said mouthrinse.
