After the temperature is reduced to the fourth temperature, the temperature reduction can be stopped, the physical and chemical indexes of the mixture are detected, and after the mixture is detected to be qualified, the mixture is discharged and stored through the discharge port 11 of the emulsifying tank body 1.

The fourth temperature in this example is preset at 38deg.C, and this temperature is determined so that the finished emulsion can be stored in hot areas and is not easily spoiled.

It should be noted that, when the emulsifying device of the present application is used to prepare the lactobacillus repair essence emulsion, the homogenization and stirring operation involved in the preparation process of the lactobacillus repair essence emulsion is performed, the first blade 321 and the second blade 322 of the stirring blade 32 in the emulsifying device are in a separated state, and the turbulence degree of the fluid is improved by increasing the number of the blades, so as to improve the homogenization and stirring effect. When the mixture is required to be discharged out of the emulsifying tank body 1 for storage, the first blade 321 and the second blade 322 can be spliced to form a conveying channel for conveying the mixture by pushing the rotating inner shaft 312, and then the mixture is output through the discharging hole 11.

In addition, the lactobacillus repair essence emulsion disclosed in the application can be produced by utilizing the existing vacuum emulsifying machine except for the preparation of the emulsifying device disclosed in the application, for example, the vacuum emulsifying machine with the model of RHJ-500L, wherein the B-phase raw material can be heated and dissolved in an oil phase pot before being added into the emulsifying pot, and the B-phase raw material is vacuumized into the emulsifying pot after being completely dissolved.

The lactic acid bacteria repair essence milk obtained by the disclosed examples and comparative examples according to the preparation method disclosed above is subjected to a safety test, a repair efficacy test, a skin moisture retention test and a corrosion protection test respectively.

1. Safety test

Selecting 100 subjects according to the specification requirements of 2015 edition of cosmetic safety technical Specification by using a human skin patch test method, wherein 10 subjects are selected in one group for 10 groups; group 1 subjects were blank, no material was added to the plaque assay wells; subjects in groups 2-10 respectively carry out patch tests for a plurality of times by using the essence emulsions in examples one to five and comparative examples one to four, and a sample to be tested is placed into a testing hole of a patch tester with the dosage of 0.020g; the test operation is specifically as follows:

applying the patch tester and blank control with the test object to the same position on the forearm curved side of each group of subjects, and applying the patch tester and blank control on skin uniformly by palm light pressure for 24h; removing the spot tester for 30min, and observing skin reaction after the indentation disappears; if the result is negative, after resting for 24 hours, the plaque tester and the blank control with the test object are added for the second time at the same position for 24 hours; removing the spot tester for 30min, and observing skin reaction after the indentation disappears; if the result is negative, after resting for 24 hours, the plaque tester and the blank control with the test object are added for the third time at the same position for 24 hours; removing the spot tester for 30min, and observing skin reaction after the indentation disappears; if the result is negative, the skin reaction condition after the patch test is observed at 24 hours and 48 hours after the patch test respectively.

Wherein, the grading standard of the skin adverse reaction is as follows:

the negative reaction is grade 0; suspicious reaction: only weak erythema was grade 1; weak positive reaction: erythema, infiltration, edema, and possibly papules of grade 2; strong positive reaction: erythema, infiltration, edema, papules, herpes, responses that may be grade 3 beyond the test area; very strong positive response (fusogenic herpes response): obvious erythema, severe infiltration, edema, and blepharospermia, the response was grade 4 beyond the test area.

The experimental results are detailed in table 1:

table 1 lactic acid bacteria repair essence milk safety test number of people

/>

As can be seen from the detection results in Table 1, after the essence emulsion disclosed by the application is applied to a subject, no adverse reaction occurs in the 48-hour patch test results, and the fact that the tested product has no adverse reaction to the skin of a human body is judged, so that the safety reaches the standard.

2. Test of repair efficacy and test of moisture retention of skin

The skin erythema index is adopted to judge the repairing effect after the essence milk is used, the skin Erythema Index (EI) reflects the condition of facial capillaries, the inflammatory degree is visually reflected, and the lower the EI value is, the better the effects of repairing skin and improving skin erythema reaction are shown.

100 subjects were selected, 50 subjects for men and women, were randomly grouped into 10 groups, and 10 for each group were respectively corresponding to a blank control group, examples one to five, comparative examples one to four, uniform clothes, exposure of both arms, and after the same period of sun exposure for 2 hours in 2022 month 7, skin erythema index and skin moisture content were respectively tested. After sun exposure, the essence emulsions of examples one to five and comparative examples one to four are respectively smeared, the blank control group is not smeared with any skin care product, and the smearing is repeated once again at intervals of 8 hours after the smearing. Skin erythema index and skin moisture content were tested after 1h and 24h of application, respectively, and the percentage decrease in skin erythema index and the percentage increase in skin moisture content after repair were counted.

Percent (%) reduction of post-repair skin erythema index = (post-repair skin erythema index before sun-repair skin erythema index after sun)/post-repair skin erythema index before sun ×100%;

percentage of increase (%) in skin moisture after repair = (moisture after repair after sun-moisture before repair after sun)/moisture before repair after sun × 100%.

The test results are shown in Table 2 below.

TABLE 2 skin erythema index and moisture content variation over time after sun exposure

The results in table 2 are combined, so that the effects of repairing, moisturizing and moisturizing can be achieved when the essence emulsion is smeared on the skin after sun-drying, and the repairing effect of the essence emulsion can be improved by increasing the contents of lactobacillus fermentation lysate and lactobacillus/soybean milk fermentation product filtrate, and the repairing effect of the essence emulsion can also be improved by increasing the content of the plant skin conditioner. The lactobacillus/soybean milk fermentation product filtrate can promote skin to absorb essence milk, so that the repairing effect and the moisturizing effect are improved. The sodium chloride can improve the repairing effect of the essence milk to a certain extent, and the chloride ions can promote the absorption of the essence milk so as to have good moisturizing effect. The sodium benzoate can also improve the repairing effect of the essence emulsion.
