Examples of the bacteriostatic effects

1. Test sample

The shampoos prepared in examples 1-3 and comparative examples 1-3 were tested using ketoconazole as a positive control.

2. Test index

Minimum Inhibitory Concentration (MIC)

It is currently believed that dandruff production is associated with hyperproliferation and proliferation of pityrosporum orbiculare (malassezia) on the scalp. The desquamation effect can be evaluated by determining and comparing the inhibition effect and the action intensity of the pityrosporum orbiculare in vitro. In vitro drug sensitivity tests were performed on malassezia furfur (m.furfurfurcbs 1878, dutch collection of microorganisms) with reference to yeast microdilution in the protocol M27-a by the american national committee for standardization of clinical laboratories (NCCLS).

3. Results of the experiment

The results of the in vitro culture strain inhibition experiments are shown in table 1:

TABLE 1

Sample name	Minimum Inhibitory Concentration (MIC)
		Example 1	38μg/ml
Example 2	34μg/ml
		Example 3	21μg/ml
Comparative example 1	71μg/ml
		Comparative example 2	67μg/ml
Comparative example 3	64μg/ml
		Ketoconazole	0.05μg/ml

Note: the active concentration of Malassezia furfur (M.furfurfurCBS1878) bacterial solution is about 5.0 × 10⁵cfu/ml。

According to test data, the shampoos in examples 1-3 and comparative examples 1-3 have certain antibacterial effect, and the antibacterial effect of the shampoos in comparative examples 1-3 is lower than that of the shampoos in examples 1-3.

Evaluation of antipruritic and antidandruff Effect

(1) Evaluation method for relieving itching and removing dandruff

The experimental population of each shampoo is 60, 30 men and 30 women, and the shampoo has the symptoms of itching and much scurf after being aged 20-60 years.

The using method comprises the following steps: the shampoo is washed twice a week, and 20-100 ml of the shampoo is used for 2 months each time according to the thickening degree of hair.

And (3) test results:

the standard of curative effect is as follows: (1) the effect is shown: the symptoms of itching, much scurf or scalp oil discharge are improved considerably; (2) the method has the following advantages: itching of the head, more dandruff or a slight reduction in the symptoms of scalp oil; (3) and (4) invalidation: no change before and after use.

(2) The evaluation of the antipruritic and anti-dandruff effect is shown in table 2:

TABLE 2

Sample (I)	Show effect	Is effective	Invalidation	Total effective rate
					Example 1	35	49	6	90％
Example 2	37	16	7	88.33％
					Example 3	40	17	3	95％
Comparative example 1	10	15	35	41.66％
					Comparative example 2	13	18	29	51.66％
Comparative example 3	17	16	27	55％
					Blank control	5	5	50	20％

From the experimental effect, the effect of the embodiment is more than that of the control example and that of the blank control example. Thus, the shampoos prepared in examples 1-3 are effective in relieving itching and removing dandruff, especially in example 3.

Testing of repair Effect

The principle is as follows: the glossiness of the hair is an important index for testing the hair care and repair effects of the shampoo. Healthy hair has uniform natural color, is black and bright, and gives people a sense of beauty full of sunlight and vitality. If the hair appears dry and yellow, it is an indication of more severe damage and immediate repair and care is required. The hair can be observed because it is a fine cylindrical or elliptical cylinder that reflects diffuse light when incident light is applied thereto.

The evaluation method comprises the following steps: 30 volunteers with similar damaged hair degrees are selected, shampoo products prepared in examples 1-3 of the invention and comparative examples 1-3 and shampoo with hair care and restoration functions of certain brand of known products sold in the market are respectively used for 3 weeks, and after the shampoo products are washed in the same way, the hair restoration degree is measured by the following measuring method: the hair tresses cleaned by the same amount of shampoo are respectively and evenly spread on a horizontal table top. After observing the respective glossiness levels of the hair strands irradiated with light, the hair strands were scored by a 6-point scale, and the higher the glossiness level was. The hair tresses were randomized and the experiment was repeated. If the results of the two times have no obvious difference, the experimental results are not accidental. The test scoring results are shown in table 3.

TABLE 3

As can be seen from Table 3, the shampoos prepared in examples 1-3 of the present invention have significant effects of repairing and caring damaged hair, which are significantly higher than the shampoos prepared in comparative examples 1-3.
