Abstract
Acidic oral compositions having reduced tooth erosion characteristics, especially acid beverages such as fruit juice drink concentrates, or oral healthcare products such as mouthwashes, are prepared by adding a calcium compound to the acid composition so that the mol ratio of calcium to acid ranges from 0.3 to 0.8, and the pH of the composition, if necessary after adjustment with an alkali, is from 3.5 to 4.5.
Claims22
A liquid composition for oral use containing a calcium compound and an acidulant characterised in that calcium is present in the range of 0.3 to 0.55 mol per mol of acid and that the proportion of calcium and acidulant in the composition is selected so that the ph of the composition is from 3.5 to 4.5:
Use of calcium as a tooth erosion inhibitor in an acidic liquid composition for oral use by adding a calcium compound to the composition so that calcium is present in the range of 0.3 to 0.55 mol per mol of acid, the amount of calcium and acidulant in the composition being selected so that the pH of the composition is from 3.5 to 4.5.
A method of reducing-the tooth erosion properties of an acidic oral composition which comprises adding a calcium compound to the acidic liquid oral composition so that calcium is present in the range of 0.3 to 0.55 mol per mol of acid, and if necessary or desired adjusting the pH by addition of an alkali so that the pH of the composition is from 3.5 to 4.5.
