Description

Technical Field

[0001] The present application relates to the technical field of scalp care, and in particular to a scalp care essence and a preparation method thereof. Background Art

[0002] The scalp is the second thinnest skin on the body after the corners of the eyes, and it contains pores, hair follicles, and sebaceous glands. Compared with the face, the scalp has larger pores, a higher density of hair follicles, a richer density of sebaceous glands, and more active sebum secretion. Based on the growth structure of the scalp, the scalp is the part that is most prone to oil production, has the highest free radical content, and is most susceptible to aging. When it comes to head toiletries, more attention is usually paid to hair care and hairdressing, while less attention is paid to the health of the scalp. The aging and inflammation of the scalp can cause thinning of hair, deterioration of hair quality, and even cause problems such as hair loss.

[0003] Due to the high work pressure, increasingly fast pace of life, irregular work and rest, people's scalp oils faster and secretes more sebum. In order to keep the scalp fresh, the cleaning power of shampoo products on the market is getting stronger and stronger. It can have a certain cleaning effect in the short term, but long-term use can easily cause dry scalp, increased dandruff, accelerated scalp aging and other problems. Currently, there are Chinese medicine extracts added to scalp care products to improve scalp problems, but the scalp does not absorb enough nutrients, so the effect is slow. Summary of the invention

[0004] In order to effectively improve the health of the scalp, the present application provides a scalp care essence and a preparation method thereof.

[0005] In the first aspect, the present application provides a scalp care essence, which adopts the following technical solution: A scalp care essence, comprising the following raw materials in parts by weight: 20-30 parts of a Chinese medicine composition extract, 0.01-0.06 parts of sodium hyaluronate, 0.2-1 parts of a thickener, 0.02-0.08 parts of ceramide, 0.01-0.04 parts of a polypeptide, and 60-80 parts of water; The Chinese medicine composition extract is obtained by boiling the Chinese medicine composition in water for extraction, and the weight ratio of the Chinese medicine composition to the water for extraction is 1:(9-11). The Chinese medicine composition comprises the following raw materials in weight: 5-11 parts of Amaranthus tricolor, 3-7 parts of Radix Astragali, 1-3 parts of Ginseng, 1-3 parts of Polygonum multiflorum, 0.5-2 parts of Mint leaves and 0.5-2 parts of Platycladus orientalis leaves.

[0006] By adopting the above technical scheme, Amaranthus tricolor has the effects of clearing away heat and dampness, cooling blood and detoxifying. Modern research has also found that it also has the effects of antibacterial and anti-inflammatory, and increasing the number of platelets. In addition, Amaranthus tricolor contains protein that can be more fully absorbed by the human body than milk, and the content of carotene, iron and calcium is also high. Amaranthus tricolor is known as a longevity vegetable and is a leader among fresh vegetables. During the research, the inventors of the present application found that its extract has the effects of cleaning the scalp, moisturizing the scalp, and improving the water-oil balance ability of the scalp, and can revitalize the overall vitality of the scalp; Radish has the effect of replenishing essence and invigorating Qi; adding the two at the same time can synergize and enhance the effect, and can achieve the effect of 1+1>2 for the skin barrier repair of the scalp; combined with the cooperation of other nutrients in the system, the health level of the scalp can be greatly improved.

[0007] Preferably, the amount of Amaranthus tricolor added to the traditional Chinese medicine composition is 8 parts by weight, and the amount of Radix Astragali added is 5 parts by weight.

[0008] By adopting the above technical solution, when the addition amount of other raw materials in the system is constant, the addition amount of Amaranthus tricolor is a key factor affecting the effect of the scalp care essence. When the addition amount is 8 parts by weight, the synergistic effect between it and the other substances in the system is relatively strong.

[0009] Preferably, the raw materials of the traditional Chinese medicine composition further include 1-5 parts by weight of liquorice.

[0010] By adopting the above technical solution, licorice is sweet and neutral in nature, can replenish qi and nourish the middle, relieve acute pain, moisten the lungs and relieve cough, and promote blood circulation and detoxify; as a blending agent, it can blend various medicines, alleviate the strong and toxic properties of other medicinal materials, and reduce the bitterness and spiciness of the medicine. By adding a certain amount of licorice, the overall effect of the Chinese medicine composition can be made milder, the irritation of the Chinese medicine composition to the scalp can be reduced, the affinity of the Chinese medicine composition to the scalp can be increased, and the absorption of nutrients by the scalp can be increased.

[0011] Preferably, the polypeptide is one or more of palmitoyl pentapeptide-4, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, carnosine, and acetyl octapeptide.

[0012] By adopting the above technical solution, the number of amino acids contained in a general peptide is from two to nine. According to the number of amino acids in the peptide, the peptide has many different names: dipeptide, tripeptide, tetrapeptide, pentapeptide, etc. Peptides composed of three or more amino acid molecules are called polypeptides. Their molecular weight is less than 10,000Da, and they can pass through semipermeable membranes and are not precipitated by trichloroacetic acid and ammonium sulfate. Palmitoyl pentapeptide-4, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, carnosine, and acetyl octapeptide are used in skin care products with clear anti-aging effects. They can effectively improve skin roughness, reduce the number of fine lines, reduce the depth and area of ​​wrinkles, etc., and are mild and non-irritating. They can penetrate the dermis to increase collagen and reverse the aging process of the skin by rebuilding from the inside out. Sodium hyaluronate applied to the skin surface can form a moisturizing and breathable film to keep the skin moisturized and shiny. Small molecule hyaluronic acid can penetrate into the dermis, promote blood microcirculation, and facilitate the skin's absorption of nutrients. It can be seen that sodium hyaluronate and polypeptides can open pores while moisturizing. The two work together to promote the scalp's absorption of nutrients and restore the scalp to a youthful state.

[0013] Preferably, the ceramide is one or more of ceramide-1, ceramide-2 and ceramide-3.

[0014] By adopting the above technical scheme, ceramide is a class of amide compounds formed by dehydration of long-chain fatty acids and the amino group of sphingosine, mainly ceramide phosphorylcholine and ceramide phosphorylethanolamine. Phospholipids are the main components of cell membranes. 40-50% of sebum in the stratum corneum is composed of ceramide. Ceramide is the main part of the intercellular matrix and plays an important role in maintaining the balance of moisture in the stratum corneum. Ceramide has a strong ability to associate with water molecules. It maintains skin moisture by forming a reticular structure in the stratum corneum. Therefore, ceramide has the function of maintaining skin moisture. Ceramide exists in all eukaryotic cells and plays an important regulatory role in life activities such as cell differentiation, proliferation, apoptosis, and aging. As the main component of intercellular lipids in the stratum corneum of the skin, ceramide not only acts as a second messenger molecule in the sphingomyelin pathway, but also plays an important role in the formation process of the epidermal stratum corneum. It has the functions of maintaining skin barrier, moisturizing, anti-aging, whitening and disease treatment. When ceramide is one or more of ceramide-1, ceramide-2, and ceramide-3, it can play this role and can cooperate with other nutrients to repair the scalp skin barrier.

[0015] Preferably, the thickener is one or more of carbomer, xanthan gum, and PEG-120 methyl glucose dioleate.

[0016] By adopting the above technical solution, the types of thickeners can be selected from materials within this range, all of which can play a thickening role and can be well compatible with other materials.

[0017] Preferably, the scalp care essence further comprises 0.01-0.03 parts by weight of a chelating agent, wherein the chelating agent is one or both of disodium ethylenediaminetetraacetate and tetrasodium ethylenediaminetetraacetate.

[0018] By adopting the above technical solution and adding these two chelating agents, the scalp care essence can form a better film on the scalp surface, which is beneficial to moisturizing the scalp, facilitating the absorption of nutrients and the production of collagen, thereby reducing TEWL to a greater extent and improving scalp elasticity.

[0019] In a second aspect, the present application provides a method for preparing a scalp care essence, using the following technical solution: A method for preparing a scalp care essence, comprising the following steps: S1. Dry and weigh the raw materials of the Chinese medicine composition, then add the water for extraction according to the weight ratio, boil and extract, and concentrate the volume of the water for extraction to 1.5-3 times the weight of the Chinese medicine composition, filter and obtain the extract of the Chinese medicine composition; S2. Add the remaining substances except the extract of the Chinese medicinal composition into water, stir until dissolved, then add the extract of the Chinese medicinal composition in S1, stir and mix, and obtain a scalp care essence.

[0020] By adopting the above technical scheme, the preparation method of the present application does not require special equipment or improvement of existing equipment. The preparation method is simple, has strong tolerance for parameters of the preparation process, is suitable for large-scale production in factories, and the products obtained have strong uniformity, high pass rate, and meet production standards.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. Amaranthus tricolor has the effects of clearing away heat and dampness, cooling blood and detoxifying. Modern research has also found that it also has the effects of antibacterial and anti-inflammatory, and increasing the number of platelets. In addition, Amaranthus tricolor contains protein that can be more fully absorbed by the human body than milk, and the content of carotene, iron and calcium is also high. Amaranthus tricolor is known as a longevity vegetable and is a leader among fresh vegetables. During the research, the inventors of the present application found that its extract has the effects of cleaning the scalp, moisturizing the scalp, and improving the water-oil balance ability of the scalp, and can revitalize the overall vitality of the scalp; Radish has the effect of replenishing essence and invigorating Qi; adding the two at the same time can synergize and enhance the effect, and can achieve the effect of 1+1>2 for the skin barrier repair of the scalp; combined with the cooperation of other nutrients in the system, it can greatly improve the health level of the scalp.

[0022] 2. After using the product for 28 days, the maximum TEWL can be reduced by 5.13g / h / m 2 , the scalp elasticity can be increased by up to 0.15; the scalp care essence prepared in this application has the effect of significantly improving the scalp barrier performance. DETAILED DESCRIPTION

[0034] Performance testing Detection method / test method Scalp care essences were prepared according to the preparation methods in Examples 1-5 and Comparative Examples 1-3, and then tested according to the following testing methods. The test results are shown in Table 2.

[0035] 1. Test Object 45 volunteers aged 20-45 were selected and randomly divided into 9 groups, with 5 people in each group; the volunteers had no obvious head diseases; one group was the control group, which did not use any head care products except normal hair washing; 2. Transepidermal Water Loss (TEWL) Test The transepidermal water loss rate (TEWL) and skin moisture content data were measured by the German CK company's skin moisture loss tester Tewameter TM300 and the scalp moisture loss test probe Tewameter TM Nano; one test point was selected on the volunteer's head, and the position of the test point was recorded using a positioning film, and the TEWL value before using the product of this application was measured, recorded as D0; the TEWL values ​​measured on the 14th and 28th days after continuous use were recorded as D14 and D28 days, respectively, and then the average value of each group was calculated; the more the TEWL value decreases, the better the skin barrier performance.

[0036] 3. Scalp elasticity difference The scheme refers to T / CAB0152-2002 Cosmetic Anti-wrinkle, Firming, Moisturizing, Oil Control, Repairing, Nourishing, Soothing 7-item Efficacy Determination Method; The scalp elasticity was measured using a skin elasticity tester Cutometer dualMPA580 from German CK Company; one test point was selected on the volunteer's head, and the position of the test point was recorded using a positioning film, the scalp elasticity value before using the product of the present application and the scalp elasticity value measured on the 28th day after continuous use were measured, the average value of each group was calculated, and then the scalp elasticity difference was calculated, where a positive number indicates an increase in scalp elasticity, and a negative number indicates a decrease in scalp elasticity.

[0037] Table 2 Test results of Examples 1-5 and Comparative Examples 1-3 It can be seen from the test data of Examples 1-5 and Comparative Examples 1-3, as well as Table 2, that after using the product of the present application for 28 days, the TEWL can be reduced by a maximum of 5.13 g / h / m 2 , the scalp elasticity can be increased by up to 0.15; this indicates that the scalp care essence prepared in this application has the effect of significantly improving the scalp barrier properties.

[0038] It can be seen from the data of Example 1 and the control group that the use of the scalp care essence of the present application can significantly reduce TEWL and effectively improve the scalp skin barrier performance; it can greatly improve the elasticity of the scalp, indicating that the scalp care essence of the present application can stimulate the production of scalp collagen, improve skin elasticity, stimulate scalp vitality, and restore the scalp to a youthful state. Combined with the test data of Comparative Examples 1-3, when Amaranthus tricolor and Radix dasyphyllae are not added, the TEWL reduction value of the scalp care essence is low, and the scalp elasticity difference is only 0.01; when Amaranthus tricolor or Radix dasyphyllae is added, although the TEWL reduction range is further reduced, the reduction range is small; when Amaranthus tricolor and Radix dasyphyllae are added at the same time, TEWL is greatly reduced and the scalp elasticity is greatly improved; it shows that Amaranthus tricolor and Radix dasyphyllae both have a certain effect of improving the scalp skin barrier performance, but when both are added at the same time, they have a synergistic effect and can have an effect of 1+1>2.

[0039] It can be seen from the test data of Examples 1-3 that when the addition amount of other raw materials in the system is constant, the addition amount of Amaranthus tricolor is a key factor affecting the effect of the scalp care essence. When the addition amount is 8 parts by weight, the synergistic effect between it and the other substances in the system is relatively strong.

[0040] Licorice is sweet and neutral in nature. It can replenish qi and tonify the middle, relieve acute pain, moisten the lungs and relieve cough, and promote blood circulation and detoxify. As a blending agent, it can blend various medicines, alleviate the potency and toxicity of other medicinal materials, and reduce the bitterness and spiciness of the medicine. By adding a certain amount of licorice, the overall effect of the Chinese medicine composition can be made milder, the irritation of the Chinese medicine composition to the scalp can be reduced, the affinity of the Chinese medicine composition to the scalp can be increased, and the absorption of nutrients by the scalp can be increased. It can be seen from the test data of Examples 1 and 4 that after adding licorice, the TEWL of the scalp care essence is reduced to a greater extent, and the scalp elasticity is better.

[0041] It can be seen from the test data of Examples 4-5 that the addition of a chelating agent helps the scalp care essence to form a better film on the scalp surface, is beneficial to the moisturizing of the scalp, and helps the absorption of nutrients and the production of collagen, thereby reducing TEWL to a greater extent and improving the elasticity of the scalp.
