  • Use of polyphosphate as a tooth erosion inhibitors in acidic compositions
    Patent number: 7279152
    Abstract: The use of polyphosphate in acidic oral compositions, especially acid beverages with a pH between 2.2 and 5.5, to alleviate or prevent the tooth damage associated with the consumption of acid. The invention may be practiced using polyphosphate alone or in combination with calcium and/or viscosity modifying polymers.

  • Oral compositions comprising a viscosity modifier for reduction of tooth erosion
    Patent number: 7276229
    Abstract: The use of viscosity modifying polymer materials, commonly used as stabilisers, thickeners and emulsifiers, as tooth erosion inhibitors in acidic compositions for oral administration, especially in acidic beverages such as fruit drinks and oral healthcare products such as mouthwashes, in which the effective pH of the composition is less than or equal to 4.5.

  • Liquid oral compositions comprising a calcium compound and an acidulant
    Patent number: 6908909
    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.
