Performance testing
1. Stability test:
The safety in use of the stick of example 1 was tested according to cosmetic safety Specification (2015). The results show that the total number of colonies, the total number of moulds and yeasts, the pseudomonas aeruginosa, staphylococcus aureus, heat-resistant coliform bacteria, mercury, arsenic, lead, cadmium and dioxane are qualified.
The essence bar of example 1 was tested for diethylene glycol and phenol according to QB/T5411-2019.
The bars of examples 1-3 were placed in a (45.+ -.1) °C environment and maintained for 24 hours, and observed for significant differences in properties after room temperature recovery from the pre-experiment. The test results are shown in FIG. 1, and example 2, example 3 and example 1 are shown in the order from left to right. The stability of the stick of example 2in a high temperature environment was poor, the stick was soft, the spread paste was prone to chipping, and the test paste was slightly melted at 45 ℃. Examples 1,3 the bars were stable.
The bars of examples 1-3 were placed in a (-8.+ -. 2) °C environment and maintained for 24 hours, and observed for significant differences in properties after room temperature recovery from the pre-experiment. The bar-shaped cream of the essence of the embodiment 3 is harder in low-temperature environment, unsmooth in skin feel, moist and high in smearing resistance. Examples 1,2 the bars were stable.
2. In-vitro weighing method, bionic material is used as sample carrier, the application process of cosmetics is simulated by directly applying on the carrier, the carrier coated with sample to be tested is placed under constant temperature and humidity (temperature: 18-27 ℃ and relative humidity: 30-70% RH) for a certain time, the mass of the sample before and after placement is weighed, and the moisture retention rate is calculated according to the formula. The moisture retention rate of the moisturizing cosmetic is measured by a weight method, and the testing principle is based on the fact that the acting forces of different moisturizing molecules in the cosmetic on water molecules are different, and the capacities of absorbing moisture and keeping moisture are slightly different. Positive control, 0.5mg/mL HA, blank control, pure water.
M 0 is the initial weight after the vehicle is smeared, and M t is the mass after the vehicle is smeared for a certain time.
Moisture retention = M t/M0 x 100%.
The test results are shown in Table 2 below. The bar graph of the test results is shown in fig. 3.
TABLE 2
Conclusion the moisture retention at various times in example 1 is shown in the above table, and it is clear that the moisture retention of both the sample group and the control group (blank, positive) gradually decreases with time. FIG. 3 is a histogram of the moisture retention of the samples at various times, showing that the moisture retention of the test sample group at various time points (30 min/1h/2h/4h/8h/24 h) is better than that of the blank group, and that there is a statistical difference in P < 0.05. In summary, example 1 has moisturizing effect.
3. Skin softening tightening anti-wrinkle test anti-wrinkle and tightening efficacy is mainly characterized by evaluating the inhibition rate of elastase by the test sample. Elastase is mainly synthesized and secreted by fibroblasts and can degrade elastin in skin to cause skin aging. The experimental principle of inhibiting elastase is that porcine pancreatic elastase and enzyme substrate are subjected to catalytic reaction, the absorbance is changed after adding active substances, and the inhibition rate of the elastase inhibitor is reflected by the change of the absorbance. Reference GDQT-SOP-163 elastase inhibition test assay. The test flow chart is shown in fig. 5. (temperature: 18-27 ℃, relative humidity: 30-70% RH) blank group: pure water. A t absorbance after reaction, absorbance before reaction of A 0.
Elastase inhibition = (a t-A0)/A0 x 100%.
The test results are shown in Table 3 below. The bar graph of the test results is shown in fig. 4.
TABLE 3 Table 3
Conclusion anti-wrinkle and tightening efficacy was primarily characterized by assessing the inhibition of elastase by the test samples. The higher the elastase inhibition rate value, the stronger the anti-wrinkle and tightening effects of the sample are indicated. The test results of example 1 are shown in Table 3/FIG. 4, the elastase inhibition rate was 48.33% when the sample was stock solution, and the elastase inhibition rate was superior to that of the blank group, the statistical difference P value was 0.000, and there was a significant difference (P < 0.05). In summary, example 1 has anti-wrinkle tightening effect.
