[0102] 2. Subjects: A total of 60 subjects, including 25 males and 35 females, aged 20-55 years old, were randomly divided into two groups, 30 in each group, meeting the voluntary inclusion criteria of the subjects;

[0103] 3. Test method: A closed test method was used. The test substance was placed in a suitable patch tester, and applied to the curved side of the subject's arm with a hypoallergenic tape. The test substance was evenly applied to the skin with the palm of the hand for 24 hours. The blank control group consisted of subjects who did not use the product.

[0104] 4. Observation results: Remove the test device after 24 hours, observe the skin reaction after 0.5h, 24h, and 48h, and record the reaction results. The skin adverse reaction level is shown in Table 2, and the test results are shown in Table 3.

[0105] Table 2 Skin reaction grading standards for skin occlusive patch test

[0106]

[0107]

[0108] Table 3 Human skin patch test results

[0109]

[0110]

[0111] It can be seen from the test data in Table 3 that among the 30 subjects, there were no cases of adverse skin reactions in Application Example 1, Application Example 2, Application Example 3, Application Example 4, Application Example 5, Application Comparative Example 1, Application Comparative Example 2, Application Comparative Example 3, Application Comparative Example 6, Application Comparative Example 7, and Application Comparative Example 10; while there was 1 case of Grade 1 adverse reaction in Application Comparative Example 4, Application Comparative Example 5, Application Comparative Example 8, and Application Comparative Example 9. It can be seen that the shampoo containing the composition of Application Examples 1-5 of the present invention is safe and non-irritating, and is safe and mild to the skin.

[0112] Test Example 2 Antibacterial Test

[0113] 2.1 Inhibition zone test

[0114] This test refers to the American Clinical Laboratory Standards Committee drug sensitivity test operation method, and the shampoo prepared by Application Examples 1-5 and Application Comparative Examples 1-10 is subjected to the Malassezia furfur inhibition zone test.

[0115] Test strain: Malassezia furfur.

[0116] Main instruments: constant temperature incubator, clean bench, hole puncher, pipette, tweezers and sterilized plate.

[0117] The experimental process includes the following steps:

[0118] (1) preparing Malassezia furfur into a bacterial suspension;

[0119] (2) Spread evenly on a Leeming & Notman medium plate, then place it on a sterile operating table and blow dry the bacterial solution on the plate;

[0120] (3) Each sample was quantitatively added to the above-mentioned plate, placed in a constant temperature incubator at 30°C for 48 hours, and the results were observed and the inhibition zone was measured. Each sample to be tested was tested three times in parallel, and the results were averaged, as shown in Table 4.

[0121] Table 4

[0122] Experimental Group Inhibition zone diameter Application Example 1 25.16mm Application Example 2 23.32mm Application Example 3 22.41mm Application Example 4 23.45mm Application Example 5 21.23mm Application Comparative Example 1 9.23mm Application Comparative Example 2 12.27mm Application Comparative Example 3 16.32mm Application Comparative Example 4 15.24mm Application Comparative Example 5 19.32mm Application Comparative Example 6 10.23mm Application Comparative Example 7 9.63mm Application Comparative Example 8 11.23mm Application Comparative Example 9 18.36mm Application Comparative Example 10 18.16mm

[0123] As can be seen from Table 4, the diameters of the inhibition zones of the shampoos prepared using Examples 1-5 are all higher than those of the shampoos prepared using Comparative Examples 1-10, and the shampoos have a highly effective effect of inhibiting Malassezia furfur.

[0124] The lack of any one or two components in the composition of the present invention, or the replacement of the components in the composition of the present invention with other components with similar efficacy, all lead to a significant reduction in the antibacterial effect; this indicates that the propylene glycol undecylenate, myrtle fruit extract and sugar isomers in the composition of the present invention can play a synergistic role, improve the antibacterial effect, and make the shampoo containing the composition of the present invention have a high efficiency antibacterial effect.

[0125] 2.2 Antibacterial rate test

[0126] Testing basis: "Test Method for Anti-dandruff Efficacy of Anti-dandruff Products" TGDCA010-2022 (official version);

[0127] Judgment basis: "Test Method for Anti-dandruff Efficacy of Anti-dandruff Products" TGDCA010-2022 (official version);

[0128] Judgment criteria: antibacterial rate;

[0129] Test bacteria: Malassezia furfur;

[0130] Concentration and time of action: 20min for stock solution;

[0131] Test method:

[0132] Preparation of test strains: Inoculate the stock strains on Leeming and Notman culture medium slants at (28±2)℃, culture for 5-7 days and take fresh culture for use. Wash the fresh culture with PBS buffer and release it slowly with PBS to about 5*10 6 CFU / mL~5*10 7 CFU / mL was used to prepare bacterial suspension for later use.

[0133] Leeming and Notman's medium:

[0134]

[0135] pH 6.2±0.2 (25℃)

[0136] Cycloheximide and chloramphenicol can be prepared into a stock solution according to the proportion, filtered and sterilized for use. After the other ingredients are fully dissolved, adjust the pH to 6.0-6.4, place at 121°C, and sterilize for 15-30 minutes. Add cycloheximide and chloramphenicol stock solutions before use.

[0137] Preparation of carrier: Use a micropipette to drop 10 μL of bacterial suspension on the sterilized carrier, dry at (36±1)℃ or air-dry at room temperature for later use.

[0138] Carrier immersion antibacterial:

[0139] Weigh the sample at 5g / tablet into a sterile plate, place it in a (20±1)℃ water bath for 5min, take the infected carrier with sterile tweezers, immerse the carrier completely in the sample, and start timing immediately. After the infected carrier and the sample interact for the specified time, take the infected carrier and add 5.0mL or other suitable volume of PBS into a test tube or homogenizing bag, shake it thoroughly, wash off the test bacteria, and mix well. According to the concentration of the bacterial solution, use PBS to dilute it 10 times, select the appropriate dilution, draw 1.0mL of the sample solution, put it into a sterilized plate, inoculate 2 plates in total, pour in Leeming and Notman culture medium, turn the plate over after solidification, place it at (28±2)℃, and count after 7 days of incubation.

[0140] The samples were replaced with PBS buffer as the control group and the above steps were followed.

[0141] Take PBS buffer and culture medium from the same batch for microbiological testing at the same time as negative control.

[0142] The experiment was repeated 5 times, and the average inhibition rate of each group was calculated.

[0143] Calculation results:

[0144] The number of recovered colonies per carrier was calculated according to formula (1):

[0145] C = (N1 + N2) / 2 * F * V (1);

[0146] Where:

[0147] C—The number of recovered colonies per carrier, in CFU / piece;

[0148] N—the number of colonies counted on each dish, in CFU;

[0149] F—dilution factor;

[0150] V—initial recovery liquid volume, in mL.

[0151] Single group antibacterial rate:

[0152] Calculate the result according to formula (2):

[0153] Y=(C0-C1) / C0*100% (2);

[0154] Where:

[0155] Y—inhibition rate (%);

[0156] C0—the average number of recovered colonies of the carrier after the control group, in CFU / piece;

[0157] C1—The average number of recovered colonies of the carrier after the test group, in CFU / piece.

[0158] The test results are shown in Table 5.

[0159] Table 5

[0160]

[0161]

[0162] It can be seen from Table 5 that the antibacterial rates of the shampoos prepared using Examples 1-5 are higher than the antibacterial rates of the shampoos prepared using Comparative Examples 1-10, and they have a highly effective effect of inhibiting Malassezia furfur.

[0163] The lack of any one or two components in the composition of the present invention, or the replacement of the components in the composition of the present invention with other components with similar efficacy, will result in a significant decrease in the antibacterial rate; this indicates that the propylene glycol undecylenate, myrtle fruit extract and sugar isomers in the composition of the present invention can play a synergistic role, improve the antibacterial effect, and make the shampoo containing the composition of the present invention have a high efficiency antibacterial effect.

[0164] Test Example 3 Human sensory evaluation
