Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
161 words
A stable mouthwash product having a pH of about 8.0 to about 9.3 and comprising approximately by weight 3 to 9% of sodium bicarbonate, 0.005 to 0.002% of a dye selected from the group consisting of F.D. & C. Blue #1, Red #4, Green #3, Red #40, Yellow #5, D.&C. Red #3, Red #19 and Red #33, 5 to 15% of ethanol or isopropanol, 0.05 to 0.4% of a herbal, medicinal or mint flavor oil, 0.01 to 4.0% of at least one member of the group consisting of nonionic and anionic emulsifiers for the flavor oil, and the balance deionized water, said product being prepared by solubilizing the sodium bicarbonate in deionized water, mixing the resulting solution with a solution of the remaining components in the ethanol or isopropanol, and filtering the sodium bicarbonate solution through a 0.1-1.0 micron filter at least about 12 hours after the formation thereof whereby said product has a bacterial concentration of less than 10 counts/mol.
