Embodiment 1
[0033] 1. Take 8g hyaluronic acid (the mass ratio of hyaluronic acid with different molecular weights is: 2000kDa:700kDa:5kDa=1:3:4), 2g sorbitol, 4g food grade baking soda, 0.2g sodium pyrophosphate, 0.05g Maltitol, added to deionized water, mixed evenly to obtain the first mixed solution;
[0034] 2. Take 1g of sodium N-lauroyl sarcosinate, 5g of hydroxyapatite, and 10g of aluminum hydroxide, and mix them evenly to obtain a mixed powder;
[0035] 3. Add the mixed powder of the above step 2 into the first mixed solution, and mix evenly to obtain a paste;
[0036] 4. Add 0.01g of potassium sorbate to 0.5mL of peppermint oil, heat in a water bath until mixed evenly, and obtain the second mixed solution;
[0037] 5. Add the second mixed solution into the above paste, and stir for 25 minutes under a vacuum condition greater than 0.94Mpa to obtain a hyaluronic acid-containing baking soda whitening toothpaste with uniform texture.
Embodiment 2
[0039] 1. Take 8g hyaluronic acid (the mass ratio of hyaluronic acid with different molecular weights is: 2000kDa:700kDa:5kDa=1:3:4), 3g sorbitol, 8g food grade baking soda, 0.5g sodium pyrophosphate, 0.3g Maltitol, added to deionized water, mixed evenly to obtain the first mixed solution;
[0040] 2. Take 1.5g of sodium N-lauroyl sarcosinate, 7g of hydroxyapatite, and 18g of aluminum hydroxide, and mix them evenly to obtain a mixed powder;
[0041] 3. Add the above mixed powder into the first mixed solution to obtain a paste;
[0042] 4. Add 0.15g potassium sorbate to 0.7mL peppermint oil, heat in a water bath until mixed evenly, and obtain the second mixed solution;
[0043] 5. Add the second mixed solution into the paste, and stir for 25 minutes under a vacuum condition greater than 0.94Mp to obtain a hyaluronic acid-containing baking soda whitening toothpaste with a uniform texture.
Embodiment 3
[0045] 1. Take 8g hyaluronic acid (the mass ratio of hyaluronic acid with different molecular weights is: 2000kDa:700kDa:5kDa=1:3:4), 5g sorbitol, 13g food grade baking soda, 0.8g sodium pyrophosphate, 0.5 g maltitol, added to deionized water, mixed uniformly to obtain the first mixed solution;
[0046] 2. Take 2.5g of sodium N-lauroyl sarcosinate, 9g of hydroxyapatite, and 25g of aluminum hydroxide, and mix them evenly to obtain a mixed powder;
[0047] 3. Add the above mixed powder into the first mixed solution to obtain a paste;
[0048] 4. Add 0.25g of potassium sorbate to 1mL of peppermint oil, heat in a water bath until mixed evenly, and obtain the second mixed solution;
[0049] 5. Add the second mixed solution into the paste, and stir for 25 minutes under a vacuum condition greater than 0.94Mp to obtain a hyaluronic acid-containing baking soda whitening toothpaste with a uniform texture.
