1. An oral care composition comprising particulate calcium carbonate in a form of microparticles a major abrasive cleaning agent, and a fluorine-providing compound as anti-caries agent, wherein the composition has a pH of above 8.5 and further comprises a fully neutralized polyacrylic acid having a molecular weight between 1000 and 250,000. 2. A composition according to Claim 1, wherein the molecular weight of polyacrylic acid is between 2500 and 100,000. 3. A composition according to Claim 2, wherein the molecular weight of polyacrylic acid is between 40000 and 70,000. 4. A composition according to Claim 1 to 3, wherein the polyacrylic acid is fully neutralized with an alkalimetal, ammonium, or (alkylol) amine comprising compound. 5. A composition according to Claim 4, wherein the fully neutrlized polyacrylic acid is sodium polyacrylate. 6. A composition according to any of Claim 1 to 5, wherein the fully neutralized polyacrylic acid is present in the composition in an amount of from 0.05-5% by weight of the composition. 7. A composition according to Claim 6, wherein the amount of neutralized polyacrylic acid is from 0.1-3% by weight of the composition. 8. The use of the fully neutralized polyacrylic acid having a molecular weight between 1000 and 250,000 as and additive which diminishes loss of active fluorine when the oral care composition is produced. |
