Embodiment 1
[0030] 1. An additive composition containing lysozyme, the formula of which is any one of formulas 1-10 in Table 1.
[0031] 2. With reference to QB2738-2012 Evaluation Method for Antibacterial and Antibacterial Effects of Daily Chemical Products, determine the inhibitory effects of the compositions of formulas 1 to 10 in Table 1 on Streptococcus mutans, Porphyromonas gingivalis, Staphylococcus aureus, and Escherichia coli . And the antibacterial effect of the corresponding content of lysozyme was tested synchronously.
[0032] 3. Experimental results
[0033] (1) As can be seen from the results in Table 1 and Table 2, the additive composition of the present invention can significantly improve the antibacterial effect of lysozyme.
[0034] In addition, the bacteriostatic rate (see Table 2) when only zinc citrate was added, and the lysozyme activity and bacteriostatic rate (see Table 3) when zinc citrate and lysozyme were added simultaneously were also measured. From the resul...
Embodiment 2
[0053] 1. A toothpaste containing lysozyme, the specific formula of the toothpaste is shown in Table 6 Application Examples 1-10. The preparation process is as follows:
[0054] (1) Water-soluble ingredients such as polyethylene glycol, tetrasodium pyrophosphate, sodium saccharin, and pigments are added to container 1, deionized water is added and stirred to dissolve; after dissolution, sorbitol is added;
[0055] (2) Add propylene glycol or glycerin and binder into container 2, stir and disperse evenly, add the dispersed rubber powder into container 1, stir and disperse;
[0056] (3) Add hydrated silica and other powders to the above dispersed system, and mix at high speed under vacuum for 15 to 20 minutes;
[0057] (4) Add essence and foaming agent, fully mix and disperse under vacuum for about 20 minutes;
[0058] (5) Dissolve lysozyme in deionized water, add it to the above dispersed system, fully mix and disperse under vacuum for about 10 minutes. The toothpaste produc...
Embodiment 3
[0064] 1. A toothpaste containing lysozyme, the specific formula of the toothpaste is shown in Table 7 Application Examples 11-15. The preparation process is the same as in Example 2.
[0065] 2. Refer to the evaluation method of QB2738-2012 antibacterial and antibacterial effects of daily chemical products, and determine the inhibitory effects of the toothpastes corresponding to Application Examples 11 to 15 on Streptococcus mutans, Porphyromonas gingivalis, Staphylococcus aureus, and Escherichia coli. Put the toothpaste of application examples 11-15 at a high temperature of 45°C for 3 months before doing the antibacterial test. The measurement results are shown in Table 7.
