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.
L'invention concerne des compositions à usage buccal de type acide, mais attaquant moins les dents, en particulier des boissons acides, telles que des jus de fruits concentrés ou des produits pour hygiène buccale, telles que des collutoires. Pour préparer ces compositions, on ajoute un composé du calcium à la composition acide de manière à ce que le rapport molaire calcium sur acide soit de 0,3 à 0,8 et que le pH de la composition soit, si nécessaire après un ajustement avec un alcali, entre 3,5 et 4,5.
