Patent Images
1. A method of reducing tooth erosion caused by acid in orally administered compositions comprising(i) providing a first acidic orally administrable composition;
- (ii) adding to said first acidic orally administrable composition;
(a) a calcium compound present in an amount of 0.01 to 0.75 mol per mole of acid;
(b) a viscosity modulating polymer material which is a polysaccharide selected from the group consisting of an alginate, locust bean gum, gellan gum, guar gum, gum arabic, tragacanth, carrageenin, acacia gum, xanthan gum, pectin, cellulose gum, or a combination or mixture thereof; and
(c) controlling or adjusting the effective pH of the resulting composition to less than or equal to 4.5, and(iii) thereby providing a second acidic orally administrable composition which has a lower tooth erosion potential than said first acidic orally administrable composition; and
(iv) orally administering said second acidic orally administrable composition to a mammal.

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.
