The step of preparing the small molecular cluster multi-effect plant water composition in the preparation method uses a freezing operation, and the small molecule water is obtained by the method of generating crystals and then melting during the freezing process. During the preparation process, the small molecule water is frozen uniformly at a specific rate so that the small molecule water is initially frozen, and the water molecules are rearranged at low temperatures to form a stable clustered small molecule water structure.

[0069] Comparative Example 5

[0070] Compared with Example 3, the only difference is that, during the preparation of the small molecular cluster multi-effect plant water composition, the plant water after being heated to room temperature is not subjected to cyclic freezing treatment, and the rest is the same as Example 3.

[0071] Comparative Example 6

[0075] The compositions prepared in Examples 1 to 5 and Comparative Examples 1 to 7 were tested as follows:

[0076] Test Example 1 Test particle size

[0077] In order to verify the particle size of water molecule clusters made of small molecular water in the composition, the half width of nuclear magnetic oxygen spectrum of the composition prepared in Examples 1 to 5 was detected by nuclear magnetic resonance instrument. The results are shown in Table 1.

[0078] Table 1

[0079]

[0080] It can be seen from Table 1 that the small molecular cluster multi-effect plant water compositions prepared in Examples 1 to 5 have a half-width below 70 Hz and can pass through the cell water channel.

[0081] Test Example 2 Testing the soothing and repairing effect

[0082] 1. Experimental Materials

[0083] 1.1 Sample information

[0084] Tested samples: Compositions prepared in Examples 1 to 5 and Comparative Examples 1 to 7

[0085] Processing of test samples: Filter the test samples with a 0.22um filter and collect the filtrate as the test sample mother liquor.

[0086] 1.2 Cells used in the experiment:

[0087] Human immortalized epidermal cells: HaCaT cells

[0088] 2. Experimental testing methods:

[0089] HaCaT cells with good growth status were plated on 96-well plates and cultured for 7 hours. After replacing serum-free basal medium and culturing for 16 hours, the old medium was discarded and the medium containing 25% of the sample was added. After 48 hours, the OD was detected by CCK8 method. 450 nm and OD 630 nm, and the effects of the tested samples on the proliferation of HaCaT cells were analyzed by t-test. The obtained HaCaT cell survival rates are shown in Table 2.

[0090] Table 2

[0091]

[0092] It can be seen from Table 2 that the survival rates of HaCaT cells in the small molecular cluster multi-effect plant water compositions prepared in Examples 1 to 5 and Comparative Example 5 are all greater than 105%, which shows that they have a certain promoting effect on the proliferation of HaCaT cells. The HaCaT cell line is a human immortalized keratinocyte cell line, and promoting its proliferation has a positive effect on skin repair, that is, it has a soothing and repairing effect.

[0093] Compared with Example 3, the survival rates of the small molecular group multi-effect plant water compositions prepared in Comparative Examples 1 to 4 for HaCaT cells are all less than 100.1%, which shows that the selection of plant raw materials has a synergistic effect on the soothing and repairing effects of the composition. The survival rate of HaCaT cells measured in Comparative Example 6 was 97.63%, indicating that in Comparative Example 6, because in the process of preparing the small molecular group multi-effect plant water composition, the temperature was cooled from room temperature to -2°C and then continued to drop to -4°C at a cooling rate of 0.3°C / min, the soothing and repairing effects of the obtained composition decreased. The survival rate of HaCaT cells measured in Comparative Example 7 was only 78.10%, indicating that in Comparative Example 7, the plant treatment liquid of angelica root, coix seed, lotus, orange fruit, and tea was directly made into a 10kg composition at a mass ratio of 1.7:4.3:54:10:30, and it was not made into small molecule water, so the composition existed in the form of non-small molecule water, which significantly affected the soothing and repairing effects of the composition.

[0094] Test Example 3 Testing the oil control and acne removal effect

[0095] 1. Experimental Materials

[0096] 1.1 Sample information

[0097] Appearance of the tested samples: Compositions prepared in Examples 1 to 5 and Comparative Examples 1 to 7

[0098] Pretreatment of the test samples: Filter the test samples with a 0.22um filter and collect the filtrate as the test sample mother liquor.

[0099] 1.2 Bacteria used in the experiment: Propionibacterium acnes

[0100] 2. Experimental detection methods

[0101] After activating the frozen Propionibacterium acnes strain, dilute the bacterial solution to 1.0x10 6 CFU / m. 100mL of diluted bacterial solution was added to each well of the 96-well plate, and 100μL of 6% sample solution was added. 100mL of erythromycin solution was added to the positive control group. The 96-well plate was placed in an anaerobic box for 48h and then taken out. The OD of each well was detected by an ELISA reader. 600nm, the bacterial content in each well was determined based on the absorbance, and the inhibition rate of Propionibacterium acnes was calculated. The results are shown in Table 3.

[0102] Table 3

[0103]

[0104] As shown in Table 3, the inhibition rate of the small molecular cluster multi-effect plant water composition prepared in Examples 1 to 5 and Comparative Example 5 on Propionibacterium acnes is greater than 40%, which shows that it has a certain promoting effect on the inhibition of Propionibacterium acnes. Propionibacterium acnes is a Gram-positive anaerobic bacterium. Inhibiting Propionibacterium acnes can improve skin infection and reduce the appearance of acne and acne, that is, it has the effect of controlling oil and removing acne.

[0105] Compared with Example 3, the inhibition rate of the small molecular group multi-effect plant water composition obtained in Comparative Examples 1 to 4 on Propionibacterium acnes is less than 40%, which shows that the selection of plant raw materials has a synergistic effect on the oil control and acne removal effect of the composition. The inhibition rate of the composition obtained in Comparative Example 6 on Propionibacterium acnes is 23.87%, indicating that because the temperature is cooled from room temperature to -2°C and then still cooled to -4°C at a cooling rate of 0.3°C / min during the preparation of the small molecular group multi-effect plant water composition, the performance of the oil control and acne removal effect of the composition is affected. The inhibition rate of the composition obtained in Comparative Example 7 on Propionibacterium acnes is 18.76%, indicating that Comparative Example 7 directly makes a 10kg composition of the plant treatment liquid of angelica root, coix seed, lotus, orange fruit, and tea in a mass ratio of 1.7:4.3:54:10:30, and does not make it into small molecule water, so the composition exists in the form of non-small molecule water, which significantly affects the performance of the oil control and acne removal effect of the composition.

[0106] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
