the compositions of the raw material components in the shampoo formulations of the 13 examples are shown in table 1 below: (unit is% by weight)

TABLE 1

The composition of the raw material components in the shampoo formulations of the 6 comparative examples are shown in table 2 below: (unit is% by weight)

TABLE 2

In vitro bacteriostasis test:

and (3) detecting the bacteriostatic effect by adopting a bacteriostatic ring method: the culture medium is agar medium, and the test strain is malassezia furfur standard strain.

Test samples: examples 1,2, 3, 4, 5 and comparative example 5

The experimental contents are as follows:

1. malassezia furfur is prepared into bacterial suspension of about 105 cfu.

2. Evenly spread on a Leeming & Notman culture medium plate, and then placed in a sterile operating platform to blow dry bacterial liquid on the plate.

3. Quantitatively adding each shampoo composition sample into the flat plate, culturing in a 30 ℃ constant temperature incubator for 5-7 days, observing the result, and recording and measuring the bacteriostatic ring condition.

The experimental results are as follows:

the results are reported as the diameter of the zone of inhibition, in units: and (4) millimeter.

The results were judged according to the national committee for standardization of clinical trials (NCCLS) standard: the diameter of the inhibition zone is less sensitive than 8mm, the diameter of the inhibition zone is low sensitive to 8-13 mm, the diameter of the inhibition zone is moderate sensitive to 13-19 mm, and the diameter of the inhibition zone is high sensitive to 19 mm.

Fig. 1 is a data comparison graph of the size of the diameter of a bacteriostatic ring obtained by performing a bacteriostatic test on malassezia with shampoo prepared under different additive amounts of coptis chinensis extract. As can be seen from FIG. 1, the Coptidis rhizoma extract has inhibitory effect on Malassezia, and the inhibitory effect is continuously enhanced with the increase of the addition amount of the extract; when the addition amount of the coptis extract reaches 5%, the bacteriostatic effect is equivalent to that of the case of 10%, and the diameter of a bacteriostatic zone reaches 16mm, so that the coptis extract with the addition amount of 5% has a good inhibitory effect on malassezia.

Wherein, fig. 2 is a data comparison graph of the size of the diameter of the inhibition ring of the shampoo prepared from the composition of the invention by using a single raw material (comparative examples 1, 4 and 6), two raw material combinations (comparative examples 2, 3 and 5) and 3 raw material combinations (example 1) to carry out the inhibition test on malassezia.

As can be seen from the results of FIG. 2, when 3 raw materials of the composition act alone, only the Coptidis rhizoma extract has inhibitory effect on Malassezia; after the 3 raw materials are combined in various ways, only the composition containing the coptis extract is effective, and the effect of inhibiting the malassezia by the coptis extract is not obviously enhanced by the addition of the other two raw materials in the composition only from the view point of inhibiting the malassezia.

Scalp oil control test:

adopting a DZCP-04-01 skin elasticity tester (skin elasticity test probe + skin oil test probe): the scalp oil content was tested by a Cutomer dual & Sebumeter (MPA580& SM 815).

Test samples: examples 1, 6, 7, 8, 9 and comparative example 3

The test method comprises the following steps: the subjects were rested for 30 minutes in a laboratory at 22 + -3 deg.C and 50 + -5% relative humidity, scalp oil content was tested using a DZCP-04-01 skin elasticity tester, 3 mean values were measured and reported as D0 data, samples were distributed to each subject, shampooed once a day for 28 days, and skin oil content was tested in a thermostated laboratory on days 7, 14 and 28, respectively, and reported as D7, D14 and D28. The oil content change rates of D7, D14 and D28 are respectively calculated according to the following formulas:

the rate of change in fat content { (fat content after use sample-fat content before use sample)/fat content before use sample } × 100%

The experimental results are as follows:

the number of each group of subjects is 10, the data results are averaged, and the oil control effect test data of the collard extract are shown in the following table 3.

TABLE 3

From the above table 3, it can be found that the larger the addition amount is, the better the oil control effect of the sedum aizoon extract on the scalp is; and when the addition amount of the collard extract is more than or equal to 1%, the oil control effect is obvious, and when the addition amount of the collard extract reaches 2%, the addition amount is continuously increased, and the oil control effect is not obviously enhanced.

Scalp moisturizing effect test:

skin moisture content test Probe (instrument software CK-MPA-Multi-Probe-AdapterFB): corneometer CM825 tests scalp stratum corneum moisture.

Test samples: examples 1, 10, 11, 12, 13 and comparative example 2

The test method comprises the following steps: subjects sit still for 30 minutes in a laboratory at a temperature of 22 + -3 deg.C and a relative humidity of 50 + -5%, measure scalp moisture content using a skin moisture content tester, measure 5 averages, and record the data as D0, distribute the samples to each subject, wash their hair once a day for 28 days, and return to the constant temperature laboratory on days 7, 14, and 28, respectively, to measure skin moisture content, which is recorded as D7, D14, and D28.

The experimental results are as follows:

the number of the subjects in each group is 10, the data results are averaged, and the data of the inulin moisturizing effect test are shown in the following table 4.

TABLE 4

Test sample	D0/C.U.	D7/C.U.	D14/C.U.	D28/C.U.
					Comparative example 2 (0%)	27.15	28.03	27.92	28.26
Example 13 (0.1%)	29.43	30.31	29.97	30.49
					Example 12 (0.5%)	28.92	29.94	30.72	32.15
Example 1 (1%)	26.53	28.72	33.74	36.40
					Example 11 (2%)	25.74	28.60	33.38	36.11
Example 10 (5%)	27.58	30.57	35.41	37.97

As can be seen from the data in Table 4 above, the moisture retention effect of inulin is positively correlated with the addition amount, the greater the addition amount of inulin, the better the moisture retention effect, and when the addition amount is 0.1-1%, the moisture content of scalp is obviously improved, and then the moisture content of scalp is gradually increased by continuously increasing the amount of inulin.

Evaluation of the anti-dandruff effect test:

test samples: comparative examples 1,2 and 3, example 1 and a commercial anti-dandruff shampoo (Qingyang anti-dandruff shampoo for men)

The test method comprises the following steps: 50 subjects with severe dandruff symptoms and hair diseases such as silver scurf and the like between 18 and 50 years of age are selected. Subjects were scored for dandruff using a5 point scale (1 point: no dandruff; 2 points: mild; 3 points: moderate; 4 points: severe; 5 points: very severe). After the subjects received the samples, the test samples were applied every 2 days for 6 weeks (42 days) for dandruff assessment at 0, 10, 21, and 42 days; after 3 weeks (21 days) the product was discontinued and further dandruff was assessed at day 63.

The experimental results are as follows:

the number of subjects in each group was 10, and the score was averaged as shown in FIG. 3.

In this test, the higher the average dandruff score, the more severe the dandruff condition is on behalf of the consumer. As can be seen from FIG. 3, the average dandruff score of consumers using the anti-dandruff composition of example 1 and the commercial samples decreased significantly during the product trial period (D0-D42), indicating that the anti-dandruff effect of the shampoo containing the anti-dandruff composition according to the present invention can reach a level equivalent to that of the commercial products, and after 10 days of use, the dandruff condition of consumers can be improved significantly;

when the consumer deactivates the product for a period of time, it can be seen by comparing the data in fig. 3 (D63) after the sample was used for 63 days that the dandruff condition of the consumer using the commercial product showed a significant rebound, whereas the dandruff condition of the consumer using the shampoo of the present invention showed no significant rebound.

In addition, as can be seen from the combination of fig. 3 and fig. 2, in the anti-dandruff composition according to the present invention, the collard extract and the inulin do not greatly contribute to the malassezia inhibition effect of the coptis extract, but in practical applications, the combination of the two raw materials and the coptis extract not only can significantly improve the anti-dandruff effect, but also can greatly improve the problem of dandruff recurrence, and achieve long-acting anti-dandruff effect.

As described above, the above examples and comparative examples are only intended to illustrate the technical solution of the present invention, not to limit it; although the present invention has been described in detail with reference to the foregoing examples and comparative examples, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments and comparative examples can be modified or some technical features can be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments and comparative examples of the present invention.
