| titleOfInvention | Preparation of zinc citrate and oral care compositions containing zinc citrate |
| abstract | The present invention provides a method of making an oral care composition comprising zinc citrate, the method comprising: (a) adding zinc oxide to a citric acid solution in a solvent to form a suspension; (b) agitating the suspension until a clear solution is obtained; and (c) adding additional oral care ingredients to the solution obtained in (b). In addition, the present invention provides a method of making an oral care composition comprising zinc citrate, the method comprising: (a) adding citric acid to a suspension of zinc oxide in a solvent; (b) agitating the suspension until a clear solution is obtained; and (c) adding additional oral care ingredients to the solution obtained in (b). In both processes, steps (a) and (b) are carried out at a temperature of from 10 ℃ to 50 ℃ and the molar ratio of zinc oxide to citric acid in step (a) is about 3: 2. |
