[0024] To better understand the technical content of the present invention, the technical solution of the present invention will be further introduced and explained below with reference to specific embodiments.

[0025] Example 1 A composition for regulating scalp microecology comprises the following components by weight percentage: 10% emu oil, 10% Melaleuca alternifolia leaf oil, 30% Brazilian green propolis, 40% hydrogenated castor oil, and the balance being water. Specifically, the weight ratio of emu oil, Melaleuca alternifolia leaf oil, Brazilian green propolis, and hydrogenated castor oil is 1:1:3:4.

[0026] A method for preparing a composition for regulating scalp microecology includes the following steps: Emu oil, Melaleuca alternifolia leaf oil, Brazilian green propolis, and hydrogenated castor oil were mixed with water and heated in a water bath to 40°C for 2 minutes to obtain a composition for regulating scalp microecology.

[0027] Compare with Example 1 Comparative Example 1 provides a composition for regulating scalp microecology. The only difference from Example 1 is that the composition for regulating scalp microecology does not contain emu oil, while all other conditions are the same.

[0028] Compare with Example 2 Comparative Example 2 provides a composition for regulating scalp microecology. The only difference from Example 1 is that the composition for regulating scalp microecology does not contain Melaleuca alternifolia leaf oil, while all other conditions are the same.

[0029] Compare with Example 3 Comparative Example 3 provides a composition for regulating scalp microecology. The only difference from Example 1 is that the composition for regulating scalp microecology does not contain Brazilian green propolis, while all other conditions are the same.

[0030] Compare with Example 4 Comparative Example 4 provides a composition for regulating scalp microecology. The only difference from Example 1 is that the composition for regulating scalp microecology does not contain emu oil and hydrogenated castor oil; all other conditions are the same.

[0031] Compare with Example 5 Example 5 was controlled with physiological saline.

[0032] Compare with Example 6 A composition for regulating scalp microecology, comprising the following components by weight percentage: 30% emu oil, 20% Melaleuca alternifolia leaf oil, 30% Brazilian green propolis, 10% hydrogenated castor oil, and the balance water.

[0033] The preparation method of the composition for regulating scalp microecology in Comparative Example 6 is the same as that in Example 1.

[0034] The compositions for regulating scalp microecology from Example 1 and Comparative Example 6 were subjected to stability tests, and the test results are shown in Table 1 below: Table 1. Stability test results of Example 1 and Control Example 6 As can be seen from the test results in Table 1, the composition for regulating scalp microecology (Comparative Example 6) made without using the component content within the scope of the present invention will cause the material to separate and affect the stability of the material.

[0035] Application of compositions that regulate scalp microecology in hair care products: Experimental Example 1 The composition (by weight, %) of each ingredient in a shampoo is shown in Table 2 below: Table 2 Raw material composition of shampoo in Experiment Example 1 (mass percentage, %) The preparation method of the shampoo in Experimental Example 1 includes the following steps: 1) Weigh each raw material according to the mass ratio; 2) First, add phase E to phase A and disperse it completely. Heat to 80°C and stir until homogeneous. Then, add phase B in sequence and stir until homogeneous. After keeping warm for 10 minutes, cool down to 45°C and add phase C. Stir until homogeneous and then add phase D. Adjust the pH. Stir until homogeneous to obtain the product.

[0036] Comparative Example 1 Comparative Example 1 provides a shampoo that differs from Test Example 1 in that it uses the composition of Control Example 1 that regulates the scalp microecology instead of Example 1 as a moisturizer, while all other conditions are the same.

[0037] Comparative Example 2 Comparative Example 2 provides a shampoo that differs from Test Example 1 in that it uses the composition of Control Example 2 that regulates the scalp microecology instead of Example 1 as a moisturizer, while all other conditions are the same.

[0038] Comparative Example 3 Comparative Example 3 provides a shampoo that differs from Test Example 1 in that it uses the composition of Control Example 3 that regulates the scalp microecology instead of Example 1 as a moisturizer, while all other conditions are the same.

[0039] Comparative Example 4 Comparative Example 4 provides a shampoo that differs from Test Example 1 in that it uses the composition of Control Example 4 that regulates the scalp microecology instead of Example 1 as a moisturizer, while all other conditions are the same.

[0040] Comparative Example 5 Comparative Example 5 provides a shampoo that differs from Test Example 1 in that it uses physiological saline from Control Example 5 instead of Example 1 as a moisturizer, while all other conditions are the same.

[0041] Comparative Example 6 Comparative Example 6 provides a shampoo that is a commercially available competitor (commercially available shampoos containing anti-dandruff agents).

[0042] The shampoos from Experimental Example 1 and Comparative Examples 1-6 were subjected to in vitro antibacterial tests.

[0043] The in vitro antibacterial test results are as follows: 1. Test strains: Malassezia, Staphylococcus aureus; 2. According to section 5.7 of QB / T 2738-2023, the inhibition ring method is used to measure the diameter of the inhibition ring (including the patch) on the bacteriostatic agent carrier and the qualitative filter. The measurement is recorded using calipers. The test is repeated three times. If the inhibition ring diameter is greater than 7 mm, the product has an antibacterial effect. If the inhibition ring diameter is not greater than 7 mm, the product has no antibacterial effect.

[0044] The in vitro antibacterial test results of Experimental Example 1 and Comparative Examples 1-6 shampoos are shown in Table 3 below: Table 3. Results of in vitro antibacterial experiments on shampoos from Experimental Example 1 and Comparative Examples 1-6 Figure 1 This is a test diagram of the Staphylococcus aureus inhibition zone diameter in the shampoo of Experimental Example 1 of the present invention; Figure 2 This is a test diagram of the diameter of the Malassezia inhibition zone in the shampoo of Experimental Example 1 of the present invention; Figure 3 This is a test diagram of the control group in the in vitro antibacterial experiment of the shampoo in Experiment Example 1 of the present invention.

[0045] Depend on Figures 1-3 As shown in Table 3, the shampoo prepared using the composition for regulating scalp microecology of the present invention (Example 1) also has excellent antibacterial ability, comparable to that of commercially available shampoos containing antibacterial agents (Comparative Example 6). It can inhibit the growth of Malassezia and Staphylococcus aureus, while retaining a small number of active bacteria. These residual active bacteria use scalp oil as nutrition, such as triglycerides, which can be metabolized by microorganisms into free fatty acid diacylglycerols and monoacylglycerols, improving the severe oiliness of the scalp and promoting the water-oil balance of the scalp. After the bacterial community has multiplied for 24-48 hours, and the series of physiological activities of the microorganisms have reached a certain level, the shampoo of Example 1 can be used again to inhibit the growth of microorganisms. The residual active bacteria continue to decompose scalp oil to multiply, thereby achieving a dynamic balance of the scalp microbiota and promoting the water-oil balance of the scalp environment, thus achieving a state of microecological balance of the scalp. Shampoos made from multiple components lacking the ability to regulate scalp microecology (Comparative Example 4) have no antibacterial effect.

[0046] The shampoos from Experiment 1, Comparative Example 4, and Comparative Example 6 were tested using oil-control paper.

[0047] Oil-control paper oil-absorbing paper test: Polyolefin film oil-absorbing paper has a special, tough texture. After absorbing oil, it leaves oil stains. The more oil stains or the darker the color of the stains, the more oil has been absorbed. Ten volunteers were recruited to rate the scalp oil stains on the scalp oil test strips according to the scalp oil test strip evaluation criteria. A score of 0-40% oil stain area was grade 1, 40-70% was grade 2, and 70-100% was grade 3. For the same test subject, a change from grade 3 to grade 2, or from grade 2 to grade 1, indicates a significant oil-control effect. A change from grade 3 to grade 1 indicates a substantial oil-control effect. The scalp oil test strip evaluation criteria are as follows: Figure 4 As shown.

[0048] The oil control test results of the oil control paper of shampoos in Experiment Example 1, Comparative Example 4, and Comparative Example 6 are shown in Table 4.

[0049] Table 4. Oil control test results of oil-control paper for shampoos in Experiment 1, Comparative Example 4, and Comparative Example 6. Figure 5 The diagram shows the corresponding scalp oil test strips before using the shampoo in Experiment Example 1. Figure 6 The diagram shows the corresponding scalp oil test strips after using the shampoo in Experiment Example 1. Figure 7 The diagram shows the corresponding scalp oil test strips before using Comparative Example 4 shampoo. Figure 8 The diagram shows the corresponding scalp oil test strips after using the shampoo in Comparative Example 4. Figure 9 The diagram shows the corresponding scalp oil test strips before using Comparative Example 6 shampoo. Figure 10 The diagram shows the corresponding scalp oil test strips after using shampoo in Comparative Example 6.

[0050] Depend on Figures 5-10 As shown in Table 4, the shampoo (Example 1) prepared using the composition for regulating scalp microecology according to the present invention has a significant oil control effect.

[0051] The shampoo from Test Example 1 of this invention was used in a test to assess the volume of hair on the crown of the head. Figure 11 A diagram showing the height of hair strands on the crown of the head before using the shampoo in Experiment Example 1 of this invention; Figure 12 A diagram showing the height of hair strands on the crown of the head after using the shampoo from Test Example 1 of this invention. Figures 11-12 It can be seen that after using the shampoo prepared with the composition for regulating scalp microecology of the present invention (Example 1), the height of the hair on the top of the head increased significantly by 2cm. This shows that the shampoo prepared with the composition for regulating scalp microecology of the present invention has the effect of making the hair on the top of the head fluffy.

[0052] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
