Whitening toothpaste

The invention relates to whitening toothpaste. The whitening toothpaste comprises activated carbon stably attached with ozone. The preparation method of the activated carbon stably attached with ozone comprises the following steps: mixing activated carbon with sodium carbonate, injecting ozone with saturated vapor pressure in an environment of 400-900 DEG C, and carrying out oxidation activation; and vacuumizing, injecting inert gas, and cooling to obtain the product. According to the whitening toothpaste provided by the invention, the ozone is used as a whitening functional component, and the activated carbon is selected as a carrier of the ozone, so that the ozone can stably exist in the whitening toothpaste and does not lose activity. 本发明涉及一种美白牙膏。所述美白牙膏包括稳定附着臭氧活性炭。稳定附着臭氧活性炭的制备方法包括将活性炭与碳酸钠混合，在400-900℃的环境中注入饱和蒸气压的臭氧，进行氧化活化；抽真空后注入惰性气体，冷却，得到。本发明提供的美白牙膏以臭氧作为美白功效成分，选用活性炭作为臭氧的载体，可以保证臭氧在其中稳定存在并且不失活性。
