Description

Technical Field

[0001] This invention belongs to the field of daily chemical product technology, specifically relating to a hair care composition for oil control, dandruff removal, and itch relief, and its preparation method. Background Technology

[0002] Excessive sebum production, dandruff, and itching are common scalp care problems. These issues are usually caused by a variety of factors, including Malassezia overgrowth, sebaceous gland imbalance, impaired scalp barrier function, and inflammatory responses. Overgrowth of Malassezia can break down triglycerides in sebum, producing irritating free fatty acids, leading to an imbalance in the scalp's microecology, causing abnormal shedding of keratinocytes and itching. Long-term use of traditional anti-dandruff agents such as zinc pyrithione may lead to drug resistance in Malassezia, while ingredients such as selenium sulfide may pose risks such as scalp irritation. Summary of the Invention

[0003] In view of this, a hair care composition for oil control, dandruff removal, and itch relief, and its preparation method are proposed to solve the above problems.

[0004] In a first aspect, the present invention provides a hair care composition for controlling oil, removing dandruff, and relieving itching, the composition comprising the following raw materials in parts by weight: 7-11 parts of turmeric extract, 3-5 parts of buttercup extract, 2-5 parts of cyperus extract, and 15-20 parts of plant fermentation extract; the raw materials of the plant fermentation extract include lemon balm leaves, artemisia capillaris, ash seeds, and amla leaves in a mass ratio of 1-3:2-5:7-9:2.5-6.5.

[0005] In this invention, turmeric extract is rich in curcumin and other active ingredients, exhibiting significant antibacterial activity against fungi such as Malassezia and Candida albicans, exerting its antibacterial effect by disrupting fungal cell membranes and inhibiting fungal biofilm formation; Ranunculus spp. extract contains alkaloids such as protopine, which have broad-spectrum antibacterial properties and exert antibacterial effects by disrupting the integrity of fungal cell membranes or interfering with their metabolic processes; Cyperus rotundus extract contains active ingredients such as linoleic acid and saponins, which exert antibacterial effects by disrupting cell membrane structure and affecting cell membrane stability and function.

[0006] In this invention, lemon balm leaves contain effective components such as rosmarinic acid and luteolin, which can inhibit inflammatory responses and reduce the stimulation of sebaceous gland cells by inflammatory factors, thereby reducing sebum secretion; Artemisia capillaris contains volatile oil components (such as β-pinene) that have an inhibitory effect on sebum-related pathogens such as Propionibacterium acnes and Staphylococcus aureus, while its flavonoid components can inhibit pro-inflammatory factors (such as IL-6 and TNF-α), reduce sebum secretion-related inflammatory responses, thereby achieving antibacterial and oil-controlling effects; Ash seeds contain components that can inhibit 5α-reductase activity, which can reduce DHT production, thereby reducing sebum secretion; Phyllanthus emblica leaves contain lignans, polyphenols, and flavonoids, which have significant free radical scavenging capabilities, can reduce oxidative stress damage to skin cells, thereby improving sebum secretion imbalance.

[0007] Preferably, the method for preparing the plant fermentation extract includes the following steps: (1) After drying lemon balm leaves, artemisia capillaris, ash tree seeds and amla leaves are crushed and sieved, they are mixed according to the formula to obtain mixed powder; (2) Mix the mixed powder and deionized water, sterilize, add compound yeast liquid for fermentation, filter, sterilize the filtrate, and obtain the plant fermentation extract.

[0008] Preferably, in step (2), the ratio of the mixed powder to deionized water is 1g:5-10mL.

[0009] Preferably, in step (2), the amount of the compound yeast liquid added is 3-7% of the mass of the mixed powder.

[0010] More preferably, in step (2), the compound yeast liquid is a mixture of sake yeast liquid and chestnut sake fission yeast liquid in a mass ratio of 1:0.4-0.7.

[0011] In this invention, sake yeast liquid and chestnut sake fissiomycin liquid are used for fermentation, which not only releases more polyphenols, flavonoids and other active ingredients, transforming them into more easily absorbed and more active forms, but also extracts aroma components from lemon balm leaves, improving the comfort of the finished product. Furthermore, the metabolic products produced during fermentation are rich in organic acids, which can regulate the pH balance of the scalp, maintain a slightly acidic environment, and inhibit the growth of harmful microorganisms such as Malassezia furfur and Microsporum canis, thereby reducing dandruff, itching and other adverse effects.

[0012] Preferably, in step (2), the fermentation conditions are 120-144h under the conditions of pH value of 5-6 and temperature of 25-35℃.

[0013] Preferably, the turmeric extract is obtained by supercritical CO2 extraction of dried and pulverized turmeric; the buttercup extract is obtained by reflux extraction of dried and pulverized buttercup roots mixed with deionized water at a material-to-liquid ratio of 1g:15-25mL; and the cyperus extract is obtained by reflux extraction of dried and pulverized cyperus rotundus mixed with 50-60wt% ethanol solution at a material-to-liquid ratio of 1g:15-25mL.

[0014] More preferably, the CO2 supercritical extraction is performed under the conditions of an extraction pressure of 20-30 MPa, an extraction temperature of 40-50℃, and a CO2 flow rate of 15-20 L / h for 50-60 min.

[0015] More preferably, the reflux extraction temperature is 80-90℃ and the extraction time is 2-3 hours.

[0016] In a second aspect, the present invention provides a method for preparing the hair care composition for oil control, dandruff removal and itch relief as described in the first aspect, the preparation method comprising the following steps: mixing the turmeric extract, white buttercup extract, cyperus extract and plant fermentation extract according to the formula amount to obtain the hair care composition.

[0017] Thirdly, the present invention provides the application of the hair care composition described in one aspect for controlling oil, removing dandruff, and relieving itching in the preparation of hair cosmetics.

[0018] Preferably, the hair cosmetic is any one of hair serum, hair oil, hair spray, hair lotion, shampoo, conditioner, or hair mask.

[0019] Compared with the prior art, the present invention has the following beneficial effects: This invention incorporates turmeric extract, ranunculus extract, cyperus extract, and plant fermentation extract into a hair care composition. The plant fermentation extract is prepared by fermenting lemon balm leaves, artemisia capillaris, ash seeds, and amla leaves with sake yeast and chestnut sake fissilla yeast, releasing more active ingredients and improving the abundance and efficacy of the plant fermentation extract. The turmeric extract, ranunculus extract, cyperus extract, and plant fermentation extract in this invention's hair care composition work synergistically to achieve excellent oil control, dandruff removal, and anti-itch effects through antibacterial, anti-inflammatory, and antioxidant pathways.

The amount of sake yeast liquid added was 5% of the mass of the mixed powder. The remaining steps and process parameters were the same as in Example 1.

[0030] Comparative Example 2 Compared with Example 1, Comparative Example 2 only added chestnut wine fissodactyly liquid for fermentation in the preparation of plant fermentation extract. The amount of chestnut wine fissodactyly added was 5% of the mass of the mixed powder. The remaining steps and process parameters were the same as in Example 1.

[0031] Comparative Example 3 Compared with Example 1, in Comparative Example 3, the amount of compound yeast liquid added in the preparation of plant fermentation extract was 1% of the mass of the mixed powder, and the remaining steps and process parameters were the same as in Example 1.

[0032] Comparative Example 4 Compared with Example 1, in Comparative Example 4, the amount of compound yeast liquid added in the preparation of plant fermentation extract was 9% of the mass of the mixed powder, and the remaining steps and process parameters were the same as in Example 1.

[0033] Comparative Example 5 Compared with Example 1, in the preparation of plant fermentation extract in Comparative Example 5, the compound yeast liquid was a mixture of sake yeast liquid and chestnut sake fission yeast liquid with a mass ratio of 0.5:1, and the remaining steps and process parameters were the same as in Example 1.

[0034] Comparative Example 6 Compared with Example 1, Comparative Example 6 replaced sake yeast liquid with brewing yeast liquid in the preparation of plant fermentation extract, while the remaining steps and process parameters were the same as in Example 1.

[0035] Comparative Example 7 Compared with Example 1, the raw materials of the plant fermentation extract described in Comparative Example 7 do not include lemon balm leaves and Artemisia capillaris, and the missing amount is made up by ash seeds and Phyllanthus emblica leaves in a mass ratio of 8:4.

[0036] Comparative Example 8 Compared with Example 1, the raw materials of the plant fermentation extract described in Comparative Example 8 do not include ash seeds and amla leaves, and the missing amount is made up by lemon balm leaves and artemisia capillaris in a mass ratio of 2:3.

[0037] Comparative Example 9 Compared with Example 1, Comparative Example 9 does not contain plant fermentation extracts, and the missing amount is made up by turmeric extract, buttercup extract and cyperus extract in a weight ratio of 9:4:3.5.

[0038] Comparative Example 10 Compared with Example 1, the hair care composition in Comparative Example 10 did not contain turmeric extract, buttercup extract, or cyperus extract; the missing amounts were made up by plant fermentation extracts.

[0039] Experimental Example 1 Referring to the antibacterial ring method in QB / T2738-2012 "Evaluation Method for Antibacterial and Bacteriostatic Effects of Daily Chemical Products", the hair care compositions prepared in Examples 1-3 and Comparative Examples 1-10 were used to conduct antibacterial tests on Microsporum canis (ATCC 36299) and Malassezia furfur (ATCC 44344). The experimental results are shown in Table 1.

[0040] Test sample: The hair care compositions prepared in Examples 1-3 and Comparative Examples 1-10 were diluted with sterile deionized water to prepare a test solution with a concentration of 2wt%.

[0041] Test strain: Microsporum canis was prepared into a 7.8 × 10⁻⁶ concentration using Sabouraud dextrose agar. 5 A bacterial suspension of CFU / mL was prepared; Malassezia furfur was diluted with PBS to a concentration of 7.9 × 10⁻⁶. 5 CFU / mL bacterial suspension.

[0042] Table 1

[0043] Malassezia furfur produces large amounts of fatty acids from scalp sebum during its growth. These fatty acids stimulate an inflammatory response in the scalp, leading to accelerated proliferation of scalp keratinocytes and resulting in excessive dandruff. Microsporum canis infection of the scalp triggers an inflammatory response, causing abnormal proliferation and shedding of scalp keratinocytes, resulting in excessive dandruff or tinea capitis. The experimental results in Table 1 show that the hair care composition prepared in this invention has a significant inhibitory effect on Microsporum canis and Malassezia furfur, and can achieve antipruritic and dandruff-removing effects by inhibiting the reproduction of harmful scalp bacteria.

[0044] Compared with Example 1, Comparative Examples 1-2 used only sake yeast liquid or chestnut sake schizophyte liquid to prepare plant fermentation extracts, and Comparative Example 6 replaced sake yeast liquid with brewer's yeast liquid, resulting in a decrease in the inhibitory effect of the prepared hair care composition on Microsporum canis and Malassezia furfur. This indicates that the present invention uses a compound fermentation liquid containing sake yeast liquid and chestnut sake schizophyte liquid for fermentation, which can increase the content of antibacterial components in plant fermentation extracts, thereby improving the antipruritic and dandruff-removing effects of the hair care composition.

[0045] Compared with Example 1, Comparative Examples 3-4 adjusted the amount of compound yeast liquid added, resulting in a decrease in the inhibitory effect of the prepared hair care composition on Microsporum canis and Malassezia furfur. This indicates that the amount of compound yeast liquid added in this invention may affect the composition of active ingredients in plant fermentation extracts by affecting the fermentation rate of fermentation bacteria on fermentation substrates, thereby affecting the effectiveness of the hair care composition.

[0046] Compared with Example 1, Comparative Example 5 adjusted the mass ratio of sake yeast liquid and chestnut sake schizophyte liquid in the compound yeast liquid, resulting in a decrease in the inhibitory effect of the prepared hair care composition on Microsporum canis and Malassezia furfur. This indicates that the mass ratio of sake yeast liquid and chestnut sake schizophyte liquid in the present invention also affects the efficacy of plant fermentation extracts, thereby affecting the use effect of the hair care composition.

[0047] Compared with Example 1, Comparative Examples 7-8 omitted some raw materials from the plant fermentation extract, resulting in a decrease in the inhibitory effect of the prepared hair care composition on Microsporum canis and Malassezia furfur. This indicates that in the present invention, lemon balm leaves, Artemisia capillaris, ash seeds, and Phyllanthus emblica leaves work together to affect the composition of active ingredients in the plant fermentation extract, thereby affecting the antipruritic and dandruff-removing effects of the hair care composition.

[0048] Compared with Example 1, Comparative Examples 9-10 omitted some raw materials in the hair care composition, resulting in a decrease in the inhibitory effect of the prepared hair care composition on Microsporum canis and Malassezia furfur. This indicates that the turmeric extract, Ranunculus spp. extract, Cyperus rotundus extract, and plant fermentation extract in this invention work synergistically to improve the antipruritic and dandruff-removing effects of the hair care composition.

[0049] Experimental Example 2 The inhibitory effect of the hair care compositions prepared in Example 1 and Comparative Examples 1-10 on 5α-reductase was tested, and the experimental procedure is as follows: (1) Sample preparation: Test sample: The hair care compositions prepared in Example 1 and Comparative Examples 1-10 were diluted with deionized water to prepare a test solution with a concentration of 5 wt%. Testosterone (T) solution: Prepare a 5 mmol / L testosterone solution using anhydrous ethanol as the solvent; NADPH (reduced coenzyme II) solution: Prepare a 2 mmol / L NADPH solution by dissolving the tetrasodium salt of NADPH in deionized water. Reaction solution: Deionized water was used as the solvent. Dithiothreitol and sodium phosphate were added to the solvent to make the final concentrations of dithiothreitol and sodium phosphate in the reaction solution 1 mmol / L and 20 mmol / L, respectively.

[0050] (2) Determination of initial 5α-reductase activity: At 37°C, 155 μL of reaction solution, 10 μL of testosterone solution, 10 μL of NADPH solution, and 20 μL of 5α-reductase were mixed sequentially to prepare a 5α-reductase reaction system. The change in absorbance of the 5α-reductase reaction system was continuously monitored at 340 nm for 4 min. The rate of change in absorbance reflected the activity of 5α-reductase and was recorded as the initial enzyme activity (Note: One unit of enzyme activity is the amount of enzyme in the 5α-reductase reaction system that causes the NADPH concentration to decrease by 1 μmol / L per minute at 37°C).

[0051] (3) Determination of 5α-reductase inhibition rate: At 37℃, 155 μL of reaction solution, 10 μL of testosterone solution, 10 μL of NADPH solution, 15 μL of test solution, and 20 μL of 5α-reductase were mixed sequentially to prepare a 5α-reductase reaction system containing the test sample. The absorbance of the 5α-reductase reaction system was continuously monitored at 340 nm for 4 min. The enzyme activity of 5α-reductase inactivation was calculated with reference to the NADPH standard curve, and the 5α-reductase inhibition rate was calculated with reference to the 5α-reductase inhibition rate formula. Each test sample was tested in triplicate, and the average value was calculated. The experimental results are shown in Table 2.

[0052] 5α-Reductase inhibition rate (%) = (Inactivated enzyme activity / Initial enzyme activity) × 100% Table 2

[0053] 5α-Reductase can convert testosterone to dihydrotestosterone (DHT) in the body, and DHT stimulates the sebaceous glands to secrete more oil. By inhibiting the activity of 5α-reductase, the production of DHT can be reduced, thereby decreasing the amount of oil secreted by the sebaceous glands. In Experiment 2, the inhibitory effect of the hair care composition prepared in this invention on 5α-reductase was evaluated by detecting the 5α-reductase inhibition rate, thereby evaluating the oil control effect of the hair care composition.

[0054] Compared to the examples, Comparative Examples 1-2 used only sake yeast or sake schizophyte yeast to prepare plant fermentation extracts, while Comparative Example 6 replaced sake yeast with brewer's yeast, resulting in a decrease in the inhibitory effect of the hair care composition on 5α-reductase. This indicates that the plant fermentation extracts prepared by fermenting with both sake yeast and sake schizophyte yeast in this invention have a synergistic effect, which can increase the content of the 5α-reductase-inhibiting active ingredient in the plant fermentation extract, thereby improving the effectiveness of the hair care composition.

[0055] Compared with the examples, the adjustment of the amount of compound yeast liquid added in Comparative Examples 3-4 resulted in a decrease in the inhibitory effect of the prepared hair care composition on 5α-reductase. This indicates that the amount of compound yeast liquid added in the present invention may affect the fermentation rate of the fermentation substrate by the fermentation bacteria, and at the same time affect the transformation and generation of metabolites during the fermentation process, thereby affecting the composition of the 5α-reductase-inhibiting active ingredients in the plant fermentation extract, and further affecting the use effect of the hair care composition.

[0056] Compared with Example 1, and based on the analysis of Comparative Example 5, the adjustment of the ratio of sake yeast and chestnut sake schizophytes in the compound yeast in Comparative Example 5 resulted in a decrease in the inhibitory effect of the prepared hair care composition on 5α-reductase. This indicates that the mass ratio of sake yeast and chestnut sake schizophytes in this invention also affects the efficacy of plant fermentation extracts, thereby affecting the use effect of the hair care composition.

[0057] Compared with Example 1, Comparative Examples 7-8 omitted some raw materials from the plant fermentation extract, resulting in a decrease in the inhibitory effect of the prepared hair care composition on 5α-reductase. This indicates that in the present invention, lemon balm leaves, artemisia capillaris, ash seeds, and amla leaves work together to affect the composition of active ingredients in the plant fermentation extract, thereby affecting the oil control effect of the hair care composition.

[0058] Compared with Example 1, Comparative Examples 9-10 omitted some of the raw materials in the hair care composition, resulting in a decrease in the inhibitory effect of the hair care composition on 5α-reductase. This indicates that the turmeric extract, buttercup extract, cyperus extract, and plant fermentation extract in this invention work synergistically to improve the oil control effect of the hair care composition.

[0059] Experimental Example 3 The hair care compositions obtained in Example 1 and Comparative Examples 7-10 were added to a shampoo base to prepare a test shampoo. Sixty individuals with dandruff and oily scalp (scalp oil content not less than 150 μg / cm³) were randomly selected. 2 The experiment was conducted on volunteers with 40 male and 20 female volunteers, who were divided into 5 groups. The volunteers washed their hair every other day and used the shampoo to be tested for 28 consecutive days. The change rate of scalp oil was detected by the Antsci Skin-SP skin tester on day 0 and day 28. The average value of the experimental data of each group of volunteers was calculated and recorded as the experimental results. The experimental results are shown in Table 3.

[0060] Scalp oil content change rate (%) = (Scalp oil content on day 28 - Scalp oil content on day 0) / (Scalp oil content on day 0) × 100% The shampoo to be tested, by weight percentage, consists of the following ingredients: 5% hair care composition, 5% butylene glycol, 5% silicone oil, 9% sodium lauroyl glutamate, 0.8% cocamide, 0.7% cocamidopropyl betaine, 0.5% phenoxyethanol, and the balance being deionized water.

[0061] Table 3

[0062] The test results show that the hair care composition prepared in this invention has excellent oil control effect when added to hair care products.

[0063] Compared with Example 1, Comparative Examples 7-8 omitted some raw materials from the plant fermentation extracts, resulting in a decrease in the oil control effect of the shampoos containing the corresponding compositions. This indicates that in the present invention, lemon balm leaves, artemisia capillaris, ash seeds, and amla leaves work together to affect the composition of active ingredients in the plant fermentation extracts, thereby affecting the shampoo's performance.

[0064] Compared with Example 1, Comparative Examples 9-10 omitted some ingredients in the hair care composition, resulting in a decrease in the oil control effect of the shampoo containing the corresponding composition. This indicates that the turmeric extract, buttercup extract, cyperus extract, and plant fermentation extract in this invention work synergistically to improve the effect of the shampoo.

[0065] The hair care composition obtained in Example 1 was added to the shampoo base to prepare the test shampoo (same as in Example 3). Forty patients with dandruff and oily scalp (scalp oil content not less than 150 μg / cm³) were randomly selected. 2 The experiment was conducted on volunteers with 20 male and 20 female participants. The volunteers washed their hair every other day and used the shampoo to be tested for 6 months. The change rate of scalp oil was measured using the Antsci Skin-SP skin analyzer at 0 days, 28 days and 6 months. The average value of the experimental data for each group of volunteers was calculated and recorded as the experimental results. The experimental results are shown in Table 4.

[0066] Scalp oil change rate 1 (%) = (Scalp oil content on day 28 - Scalp oil content on day 0) / (Scalp oil content on day 0) × 100% Scalp oil change rate 2 (%) = (Scalp oil content at 6 months - Scalp oil content at 28 days) / (Scalp oil content at 28 days) × 100% Table 4

[0067] The experimental results show that the hair care composition prepared in this invention has a long-term oil control effect when added to hair care products. At the same time, the hair care composition does not damage the scalp's natural barrier, causing the scalp to become dry and sensitive, and thus does not stimulate the sebaceous glands to secrete more oil to repair the damaged skin barrier. Instead, it does not aggravate problems such as oily scalp.

[0068] The above description is merely a preferred embodiment of the present invention and is not intended to limit this application. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
