Toothpaste bacteriostasis test
Taking a clean pollution-free filter paper sheet, beating the filter paper sheet into a filter paper sheet with the diameter of 4mm by using a puncher, loading the filter paper sheet into a test tube, carrying out autoclave at 121 ℃ for 15min, taking out the filter paper sheet, and placing the filter paper sheet in a drying box at 80 ℃ for drying; then, 50mg of toothpaste was added to each filter paper sheet, and the mixture was naturally dried in a constant temperature oven (37 ℃) for 5min for use.
Uniformly smearing and inoculating activated staphylococcus aureus, escherichia coli, candida albicans, porphyromonas gingivalis and klebsiella pneumoniae on a nutrient agar culture dish plate, and then pasting toothpaste filter paper sheets of different test groups on the inoculated nutrient agar culture dish plate, wherein the distance between the centers of the toothpaste filter paper sheets is not less than 20mm, and the distance between the centers of the toothpaste filter paper sheets and the periphery of the culture medium plate is not less than 15 mm. The culture medium is divided into two groups, one group is as follows: each medium was separately applied with 1 negative control of distilled water, 5 filter paper sheets of the toothpastes of examples 1-5; the two groups are: each culture medium was separately pasted with 1 negative control of distilled water, 5 filter paper sheets of the toothpastes of example 5 and comparative examples 1-4; three replicates per set. The culture plate is covered and placed in a constant temperature incubator at 37 ℃, and the result can be observed after the culture is carried out for 24 hours. And (3) placing the nutrient agar culture dish inoculated with the porphyromonas gingivalis in an anaerobic bag at 37 ℃ to grow and observe the result. The size of the zone of inhibition was measured to include the diameter and size of the negative patch. See table 1.
TABLE 1
As can be seen from Table 1, examples 1-5 have better bacteriostatic effects on Staphylococcus aureus, Escherichia coli, Candida albicans, Porphyromonas gingivalis and Klebsiella pneumoniae than the distilled water control group, especially have stronger bacteriostatic effects on Porphyromonas gingivalis and Klebsiella pneumoniae, and the size of the bacteriostatic ring is 12.9-16.3 mm. Therefore, the agilawood toothpaste has antibacterial property on common oral bacteria and fungi, and also has strong antibacterial property on porphyromonas gingivalis and klebsiella pneumoniae contained in the oral cavity of smokers. In addition, the antibacterial activity of the agilawood toothpaste prepared in examples 4-5 on porphyromonas gingivalis and klebsiella pneumoniae is obviously superior to that of examples 1-3, which shows that after the anti-allergen material is added, the antibacterial activity of the agilawood toothpaste on porphyromonas gingivalis and klebsiella pneumoniae is enhanced; the antibacterial activity of the anti-allergen material in the comparative example 1 to porphyromonas gingivalis and klebsiella pneumoniae is not much different from that in the example 5 because the amelogenin extract is not added, which indicates that the amelogenin extract in the anti-allergen material plays a main role in the antibacterial activity to porphyromonas gingivalis and klebsiella pneumoniae.
As can be seen from comparison between example 5 and comparative examples 2-3, the antibacterial activity of the agilawood toothpaste is affected due to different addition sequences of the components in the preparation of the agilawood toothpaste, specifically, in comparative example 2, the humectant and the thickener are mixed, except for glycerin which is insoluble in water, the other humectants cannot well disperse the thickener uniformly, so that the adsorption of the functional thickener on the functional agent is directly affected, and the antibacterial activity of the toothpaste is further affected; mixing all ingredients of the toothpaste together in comparative example 3 also affected the better formation of the network structure colloid by the thickener and the uniform adsorption of other ingredients on the colloid. The silicon dioxide used as the abrasive in example 5 is insoluble in water, and is firstly mixed with the thickening agent, the thickening agent is uniformly dispersed, and finally the foaming agent is added to enable the silicon dioxide to be adsorbed on the surface of the toothpaste more, so that the foaming effect is improved.
It can be seen from example 5 and comparative example 4 that, the toothpaste has a certain bacteriostatic action only on escherichia coli and candida albicans without adding the agilawood pollen, and therefore, the agilawood pollen in the toothpaste mainly has a bacteriostatic action on staphylococcus aureus, escherichia coli, candida albicans, porphyromonas gingivalis and klebsiella pneumoniae, while the comparative example 4 has a certain bacteriostatic action only on escherichia coli and candida albicans and possibly has a bacteriostatic action on the weak alkalinity of sodium bicarbonate in the toothpaste.
Toothpaste stability test
The shelf life of the toothpaste is generally three years, so that the toothpaste is subjected to an accelerated aging test, the condition in the shelf life is simulated, and the stability of the toothpaste is judged.
The prepared toothpaste is stored in a constant temperature oven (the aging of the paste is accelerated by the temperature of 45 ℃) at the temperature of 45 ℃, the toothpaste is taken out at the time of 3 months, the change of appearance, fragrance, p H value and the like is observed, and the stability within the shelf life of 3 years is judged according to the result. Three replicates were run per group.
TABLE 2
As can be seen from Table 2, compared with example 5, comparative example 4 has no agilawood powder, the toothpaste has a fine appearance, is moderate in thickness and fragrance, and has a reduced pH value, so that the agilawood powder directly influences the stability of the toothpaste; while the toothpaste of examples 1-4 and comparative examples 1-3 has normal appearance, stable fragrance and stable pH value, it can be seen that the addition of the eaglewood leaves and the agilawood flower extract or the eaglewood leaves and the agilawood pollen can keep the stability of the toothpaste, and the main reason is that the oxidation resistance of the compounds in the eaglewood leaves and the agilawood flower extract or the eaglewood leaves and the agilawood pollen maintains the stability of the toothpaste body.
In addition, the comparative examples 2-3 have a finer appearance or contain excessively hard particles, compared to example 5, mainly due to the order of addition of the agilawood components in the preparation process of the agilawood toothpaste.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
