Description

Technical Field

[0001] The present invention relates to the technical field of daily chemical products, and particularly relates to an anti-dandruff, anti-itching and anti-hair loss plant composition, a washing and hair care product, a preparation method and an application thereof. Background Art

[0002] Dandruff, also known as scurf, refers to small flakes of skin that shed from the scalp. The generation of dandruff is usually related to factors such as excessive scalp dryness, excessive sebum secretion, and the growth of dandruff-causing bacteria. The main component of dandruff is dead keratinocytes, and when these keratinocytes shed, dandruff is formed. The presence of dandruff not only makes the scalp itchy but may also cause certain troubles and embarrassments to people. Therefore, keeping the scalp clean and moisturized and reasonably using hair washing and hair care products are important measures for preventing and improving dandruff problems.

[0003] Hair loss refers to the excessive shedding or thinning of hair, resulting in a decrease in the number of hairs and hair thinning. Hair loss can be divided into two types: temporary hair loss and permanent hair loss. Temporary hair loss is usually caused by the following factors: stress, diseases, drug side effects, seasonal changes, after pregnancy or childbirth, malnutrition, etc. Temporary hair loss can usually be alleviated or reversed by improving lifestyle, reducing stress, adjusting diet, treating underlying diseases, etc. Permanent hair loss is usually caused by genetic factors, hormonal imbalance, aging, etc., and is difficult to reverse. The most common types of permanent hair loss are male pattern hair loss and female pattern hair loss. Male pattern hair loss shows signs of gradual hair loss at the frontal hairline and the top of the head, while female pattern hair loss causes the hair to gradually thin. Methods for treating permanent hair loss include drug treatment, hair transplantation surgery, etc.

[0004] Plant extracts have been widely used in hair washing and hair care products due to their advantages of safety and remarkable effects. For example, Chinese Patent CN106038388A discloses a traditional Chinese medicine shampoo and a preparation method thereof, which include the following components in parts by weight: 5 - 88 parts of ginger, 3 - 85 parts of sapindus mukorossi, 3 - 85 parts of tea seeds, 3 - 85 parts of Chinese honey locust, 3 - 65 parts of processed fleece-flower root, 3 - 65 parts of wild chrysanthemum, 3 - 24 parts of mulberry fruits, 3 - 24 parts of biota orientalis leaves, 3 - 24 parts of mulberry leaves, 3 - 23 parts of eclipta prostrata, 3 - 23 parts of ligusticum wallichii, 3 - 23 parts of salvia miltiorrhiza, 3 - 23 parts of artemisia annua, 3 - 23 parts of pine needles, 3 - 23 parts of poria cocos, 3 - 21 parts of polygonatum sibiricum, 3 - 21 parts of angelica sinensis, 3 - 21 parts of cnidium monnieri, 3 - 18 parts of cinnamon, 3 - 18 parts of Chinese chive seeds, 3 - 15 parts of ginseng, 3 - 15 parts of star anise, 3 - 15 parts of cloves, 0.5 - 3 parts of peppermint oil and 2 - 8 parts of camellia oil; after the traditional Chinese medicine components are soaked, decocted until boiling, and kept boiling for 30 - 180 minutes, the medicinal liquid is filtered and concentrated under vacuum at low temperature, and the prepared shampoo does not contain toxic chemicals such as silicone oil, and achieves the effects of conditioning the health of the scalp hair follicles, nourishing hair, removing dandruff, preventing hair loss and promoting hair growth, and blackening hair.

[0005] For another example, Chinese Patent CN110302129A discloses a hair-growing and anti-hair-loss scalp care solution, which contains the following components in parts by weight of the composition: 0.5-17 parts of a traditional Chinese medicine microbial two-way fermentation concentrate, 70-96.3 parts of a traditional Chinese medicine extract, 1.5-5 parts of glycerol, 1.5-5 parts of propylene glycol, and 0.2-3 parts of panthenol. The traditional Chinese medicine microbial two-way fermentation concentrate is obtained by performing liquid two-way fermentation of Ganoderma lucidum strains with ginseng roots, notoginseng roots, and angelica roots respectively. The traditional Chinese medicine extract is obtained by performing alcohol-water extraction on appropriate amounts of Ganoderma atrum, Rhinacanthus nasutus, ginger roots, sandalwood, and Platycladus orientalis. This invention utilizes the traditional Chinese medicine two-way fermentation technology to decompose the cell walls of the drugs in the formula, promote the release of active ingredients. At the same time, various enzymes produced by microbial metabolism can decompose macromolecules into small molecules, remove macromolecular impurities, enhance the medicinal effect, and reduce the toxic and side effects. The scalp care solution prepared by this invention can promote scalp blood circulation, stimulate the vitality of hair follicles, and achieve the purpose of hair growth and anti-hair loss.

[0006] Currently, plant fermentation composition extracts play an important role in scalp health and hair quality improvement. Plant fermentation composition extracts are extracted from natural plants and are more natural and safe compared to some chemically synthesized ingredients. For those who are sensitive to chemical components or pursue natural hair care products, plant fermentation composition extracts are a good choice. Currently, plant formula products with good anti-dandruff, anti-itching, and anti-hair loss effects are still relatively lacking. Summary of the Invention

Others are the same.

[0091] Result Detection

[0092] 1. Anti-dandruff and antipruritic effect

[0093] The generation of dandruff is largely related to the overgrowth of Malassezia. When Malassezia multiplies in large numbers, it decomposes sebum to produce fatty acids, which stimulate the scalp, causing skin cells to shed rapidly and form dandruff. At the same time, Malassezia can also cause scalp inflammation, exacerbating the dandruff problem.

[0094] Detection method: The test samples are the shampoos prepared in Examples 1 - 8 and Comparative Examples 1 - 4 above. According to the amount of dandruff and the degree of itching, 10 patients with mild, moderate, and severe conditions were selected respectively, and the shampoo of the present invention was continuously used for 14 days according to their personal shampoo usage habits.

[0095] The judgment criteria are as follows:

[0096] Mild: Only a small amount of dandruff can be seen with the naked eye, and the patient feels slightly itchy scalp.

[0097] Moderate: Obvious dandruff can be seen with the naked eye, and the patient feels itchy scalp.

[0098] Severe: A large amount of dandruff can be seen with the naked eye, and the patient feels extremely itchy scalp.

[0099] Before use and on the 14th day, observe the changes with a scalp analysis instrument, and collect samples from a fixed area (1 cm) of the scalp with a detection card. 2Malassezia samples were stained, and the number of Malassezia before use (D0) and the number of Malassezia on the 14th day (D14) were counted, and the change rate was calculated as follows:

[0100] Change rate (%) = (D0 - D14) / D0 × 100%.

[0101] The detection results of the change in the number of Malassezia are shown in Table 2:

[0102] Table 2.

[0103]

[0104] As can be seen from Table 2, after using the shampoo prepared in the examples and comparative examples of the present invention for 14 days, the number of Malassezia decreased. Comparing the results of Example 1 - Comparative Example 7 shows that different combinations of plant components and changes in the compounding ratio will affect the antibacterial effect. Only under specific raw material compositions and ratios can a significantly improved antibacterial effect be achieved. Among them, Example 1 had the largest change rate of Malassezia, that is, the best antibacterial effect. Therefore, 15 parts of Acorus tatarinowii, 12 parts of Platycladus orientalis, 10 parts of Eclipta prostrata, 8 parts of Ligustrum lucidum, 5 parts of Portulaca oleracea, and 3 parts of Panax ginseng were the optimal ratios. From Examples 5 - 8, it can be seen that the addition amount of the anti-dandruff, anti-itching, and anti-hair loss plant composition also affects the antibacterial effect. When the addition amount is 5%, the best antibacterial effect is achieved. In summary, the shampoo of the present invention can effectively inhibit the reproduction of Malassezia, which is beneficial to regulating the scalp microecological balance and restoring scalp health.

[0105] Before and 14 days after use, the subjects were tested with a scalp analysis instrument, and the symptoms of dandruff and itching were compared before and after use.

[0106] Judgment criteria:

[0107] Marked effect: Visible dandruff was significantly reduced to almost invisible, and the patient felt that the itching symptom completely disappeared;

[0108] Effective: Visible dandruff was significantly reduced, and the patient felt that the itching symptom basically disappeared;

[0109] Improved: Visible dandruff was slightly reduced, and the patient felt that the itching symptom was alleviated;

[0110] Ineffective: Visible dandruff showed almost no change, and the patient felt that the itching symptom was not improved.

[0111] The evaluation results are shown in Table 3:

[0112] Table 3.

[0113]

[0114] The results show that Examples 1 - 8 of the present invention have good anti-dandruff and itch-relieving effects on mild, moderate, and severe patients. The results of Comparative Examples 1 - 4 show that after some components are missing in the raw materials, the anti-dandruff effect is significantly reduced. Thus, it can be seen that the raw materials of the present invention play a synergistic role. By comparing Examples 5 - 8, it can be known that the addition amount of different anti-dandruff, itch-relieving, and anti-hair-loss plant compositions will affect the anti-dandruff and itch-relieving effects. When the addition amount is 5%, the best anti-dandruff and itch-relieving effects are achieved.

[0115] 2. Anti-hair-loss effect

[0116] The human trial test of anti-hair-loss cosmetics was carried out in accordance with the "Technical Specifications for Cosmetics Safety" (2015 Edition).

[0117] The selected subjects (healthy men or women aged 20 - 60 years old who meet the inclusion criteria) were screened. The qualified subjects were grouped according to each test sample, with 10 people in each group. During the test, the subjects in each group continuously used the shampoo of the present invention for 10 weeks according to their personal shampoo usage habits, and other products of the same type were not allowed to be used during the test period.

[0118] Before the test and 10 weeks after the test, the hair loss was counted by the 50 - combing method, and the local hair density was measured by Photomax pro Trichoscan (unit: roots / cm 2 )

[0119] The change rate of hair loss measurement (%) = (the amount of hair loss before the test - the amount of hair loss after 10 weeks) / the amount of hair loss before the test × 100%.

[0120] The change rate of local hair density = (the local hair density after 10 weeks - the local hair density before the test) / the local hair density before the test × 100%.

[0121] The test results are shown in Table 4 (in Table 4, each test result is the average value of the subjects in each group):

[0122] Table 4.

[0123]

[0124] As can be seen from the results in Table 4, compared with before use (i.e., before testing), after using the shampoo prepared in the embodiments of the present invention for 10 weeks (i.e., after 10 weeks of testing), the hair loss count can be reduced by 16.54% - 27.57%, and the local hair density can be increased by 1.13% - 4.21%, showing good anti - hair - loss effects. By comparing Examples 1 - 7, it can be known that when using different proportions of plant components in compounding and changing the compounding ratio, the anti - hair - loss effect will be affected. Among them, the change rate of hair loss measurement in Example 1 is the largest, that is, the anti - hair - loss effect is the best. Therefore, 15 parts of Acorus tatarinowii, 12 parts of Platycladus orientalis, 10 parts of Eclipta prostrata, 8 parts of Ligustrum lucidum, 5 parts of Portulaca oleracea, and 3 parts of Panax ginseng are the optimal ratios. The results of Examples 5 - 8 show that different addition amounts of the anti - dandruff, anti - itching, and anti - hair - loss plant fermentation extraction composition will also affect the anti - hair - loss effect. When the addition amount is 5%, the best anti - hair - loss effect is achieved.

[0125] Meanwhile, the results of the human trial test of the shampoo prepared in each embodiment of the present invention show no skin adverse reactions.

[0126] 3. Physical and chemical property detection of the shampoo

[0127] (1) Viscosity detection

[0128] Samples of the shampoo prepared in the examples and comparative examples were taken and detected with a viscometer. The measured viscosity distribution ranges were all between 8000 - 12000 mPa•s.

[0129] (2) pH detection

[0130] Samples of the shampoo prepared in the examples and comparative examples were taken and measured with a pH meter. The measured pH values were distributed between 5.5 - 6.5.

[0131] (3) Stability test

[0132] Samples of the shampoo prepared in the examples were taken, packaged in transparent cosmetic bottles, and placed under the experimental conditions of a light box, - 15°C, 4°C, 25°C, and 45°C respectively. A continuous 3 - month test was carried out on the appearance, fragrance, pH value, viscosity, and other items to observe whether there were any adverse phenomena such as water separation, stratification, separation, precipitation, color change, peculiar smell, and demulsification. The test results show that none of the above - mentioned adverse results occurred during the test, indicating good stability.

[0133] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
