Description

Technical Field

[0001] The invention belongs to the technical field of daily chemical products, and particularly relates to a hair growth and scalp care essence and a preparation method thereof. Background Art

[0002] With the development of the times, the pace of life is getting faster and faster, and the number of people suffering from hair loss is getting younger and younger. Hair loss refers to the phenomenon of hair loss. Normal hair loss is hair in the regression and resting phases. Since the hair entering the regression phase and the hair entering the new growth phase are constantly in a dynamic balance, the normal amount of hair can be maintained. Pathological hair loss refers to abnormal or excessive hair loss, such as neurotic hair loss caused by mental stress. The occurrence of hair loss will seriously affect people's quality of life and mental health, so a product with excellent hair care effect is needed to improve the hair loss condition.

[0003] Currently, hair loss symptoms are generally improved by using essences with hair care effects. This kind of essence adds ingredients with hair care effects such as plant extracts and diaminopyrimidine oxides to the original essence, so its components are more than conventional essences. Since impurities will precipitate out during the extraction of plant extracts, flocculants are generally used to flocculate and remove impurities. However, conventional flocculants are used in large quantities for flocculating plant extracts, and have poor high temperature resistance, resulting in poor flocculation effect and low impurity removal rate, which in turn affects the stability of the essence and reduces the hair care effect of the hair care essence. Summary of the invention

[0004] The purpose of the present invention is to provide a hair growth and scalp care essence and a preparation method thereof.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention comprises the following steps: A hair growth and scalp care essence, comprising the following components in parts by weight: 90~100 parts of water, 0.4~0.6 parts of glyceryl polyether-26, 2~4 parts of PEG / PPG-17 / 6 copolymer, 2~4 parts of dipropylene glycol, 0.1~0.3 parts of niacinamide, 1~3 parts of isopentyl glycol, 0.6~0.8 parts of p-hydroxyacetophenone, 8~10 parts of 1,2-hexanediol, 0.5~0.7 parts of jojoba wax PEG-120 esters, 1.2~1.4 parts of betaine, 0.2~0.4 parts of sodium hyaluronate, 0.3~0.4 parts of biotin, 2~4 parts of plant extracts, 0.1~0.3 parts of hydrogenated castor Oil, 0.1-0.3 parts of sodium polyacrylate, 0.5-0.7 parts of rosemary oil, 0.4-0.6 parts of ylang-ylang oil, 0.8-1 parts of bergamot oil, 0.9-1.1 parts of starch dextrin, 0.02-0.04 parts of xanthan gum, 0.08-0.1 parts of sodium alginate, 0.3-0.5 parts of hydrolyzed sclerotium gum, 0.6-0.8 parts of diaminopyrimidine oxide, 1-2 parts of caffeine, 0.3-0.5 parts of avenanthramide, 0.4-0.6 parts of pyrrolidine diaminopyrimidine oxide and 14-16 parts of butanediol, the specific preparation steps are: (1) Add xanthan gum to 7-11 parts of butylene glycol and stir until uniform, then add jojoba wax PEG-120 ester, p-hydroxyacetophenone, starch dextrin and hydrolyzed sclerotium gum, heat to 80-85°C and stir to obtain mixture a; (2) Add glyceryl polyether-26, PEG / PPG-17 / 6 copolymer, niacinamide, betaine, sodium hyaluronate, biotin, sodium polyacrylate, sodium alginate, diaminopyrimidine oxide and caffeine into water and heat the water to 80-85° C. and stir evenly, then continue to add mixture a and stir until the mixture is uniform to obtain mixture b; (3) adding 1,2-hexanediol, plant extract, hydrogenated castor oil, rosemary oil, ylang-ylang oil, bergamot oil and avenanthramide to dipropylene glycol and isoprene glycol, heating to 45-50° C. and stirring to obtain a mixture C; (4) heating pyrrolidine diaminopyrimidine oxide and 5-7 parts of butanediol to 50-55°C and stirring to obtain a mixture d; (5) Add mixture c and mixture d to mixture b while it is still hot and stir until the mixture is evenly mixed. After cooling, the hair growth and scalp care essence is obtained.

[0006] The plant extract comprises Platycladus orientalis leaf extract, Angelica sinensis root extract and Ginger root extract, and the specific preparation steps are as follows: The Platycladus orientalis leaves, angelica roots and ginger roots were washed and dried, and then crushed and passed through a 20-mesh sieve. Then, the Platycladus orientalis leaves, angelica roots and ginger roots were mixed in a mass ratio of 1-1.2:0.8-1:0.7-0.9 to obtain a mixture a. The mixture a and a 50% volume fraction ethanol solution were mixed in a solid-liquid ratio of 1:16-18 g / ml, heated to 70-80°C, refluxed and stirred for extraction for 180-240 minutes, and then 0.6%-0.8% of the mass of the mixture a stable flocculant was added, and the stirring was continued for 8-10 minutes. Then, the mixture was kept warm and allowed to stand for 20-30 minutes, and the filtrate was filtered while hot to obtain a filtrate. Then, the filtrate was concentrated by rotary evaporation to an extract with a relative density of 1.10-1.20 at 80°C, and finally, deionized water was added to the extract to obtain a solution with a mass concentration of 210-220 mg / mL; Among them, the stable flocculants are specifically: Chitosan and isobutanol were mixed in a mass ratio of 1:24-26, and then citric acid solution was added to adjust the pH value to 6.5-7, and stirred at room temperature for 60-70 minutes, and then 0.7-0.8 times the mass of chitosan (3-chloro-2-hydroxypropyl) (2-hydroxyethyl) dimethylammonium chloride was added and stirred until uniform, and the temperature was raised to 85-95°C and stirred for 6.5-7.5 hours.

[0028] test: Part of the hair growth and scalp care essence prepared in Example 1 to Example 8 was placed at -20°C and 50°C for 30 hours, respectively. Then part of the hair growth and scalp care essence was placed at 30°C and rotated at 2500r / min for 45min. The states of the essence after treatment under the three conditions were observed. The result at -20°C was recorded as a, the result at 50°C was recorded as b, and the result at 30°C was recorded as c. The specific data are shown in Table 1.

[0029] 80 volunteers with severe hair loss symptoms were selected and randomly divided into 8 groups. They used one of the above-mentioned treated hair growth and scalp care essences every 10 days. The hair care effects of the volunteers were observed after 30 and 60 days of use, and their hair care grades were evaluated. Grade A means that hair loss symptoms were slightly improved and no new hair was generated, Grade B means that hair loss symptoms were greatly improved and a small amount of new hair was generated, Grade C means that hair loss symptoms were significantly improved and some new hair was generated, and Grade D means that there were no hair loss symptoms and a large amount of new hair was generated. The specific data are shown in Table 2.

[0030]

[0031]

[0032] It can be seen from Table 1 that the essences of Examples 1 to 3 have the best stability, and no precipitation occurs under the three conditions. The reason why the stability of the essence of Example 4 is significantly reduced may be that after the stable flocculant is replaced by polyaluminium chloride, polyaluminium chloride has poor stability under high temperature and alkaline conditions, and the flocculation effect is not good, which in turn affects the stability of the essence. The reason why the stability of the essence of Example 5 is significantly reduced may be that after (3-chloro-2-hydroxypropyl)(2-hydroxyethyl)dimethylammonium chloride is replaced by 2-chloroethyltrimethylammonium chloride, the hydrophilicity of 2-chloroethyltrimethylammonium chloride is not as good as that of (3-chloro-2-hydroxypropyl)(2-hydroxyethyl)dimethylammonium chloride. The reason why the stability of the essence of Example 6 is not as good as that of Example 1 may be that the pH value is adjusted too low when preparing the stable flocculant, and the chitosan is not fully alkalized, which affects the modification effect of the flocculant; the reason why the stability of the essence of Example 7 is not as good as that of Example 1 may be that the stable flocculant is not washed with a 95% volume fraction solution, and impurities on the surface of the stable flocculant will affect the subsequent flocculation treatment; the reason why the stability of the essence of Example 8 is not as good as that of Example 1 may be that the flocculation treatment is not carried out under heating, which affects the flocculation effect of the stable flocculant.

[0033] It can also be seen from Table 2 that the essences of Examples 1 to 3 also have excellent hair care effects after treatment, while the hair care effects of the remaining examples are reduced to varying degrees due to the poorer stability of the essences, indicating that the essences prepared by the present invention have good hair care effects.

Then, the Platycladus orientalis leaves, angelica roots and ginger roots are mixed in a mass ratio of 1-1.2:0.8-1:0.7-0.9 to obtain a mixture a. The mixture a and a 50% volume fraction ethanol solution are mixed in a solid-liquid ratio of 1:16-18 g / ml, and the mixture is heated to 70-80°C and refluxed and stirred for extraction for 180-240 minutes. Then, 0.6%-0.8% of the mass of the mixture a stable flocculant is added, and stirring is continued for 8-10 minutes. Then, the mixture is kept warm and allowed to stand for 20-30 minutes, and a filtrate is filtered while hot to obtain a filtrate. Then, the filtrate is concentrated by rotary evaporation to an extract with a relative density of 1.10-1.20 at 80°C, and finally, deionized water is added to the extract to obtain a solution with a mass concentration of 210-220 mg / mL.

4. The hair growth and scalp care essence according to claim 3, characterized in that: The stable flocculant is specifically: Chitosan and isobutanol were mixed in a mass ratio of 1:24-26, and then citric acid solution was added to adjust the pH value to 6.5-7, and stirred at room temperature for 60-70 minutes, and then 0.7-0.8 times the mass of chitosan (3-chloro-2-hydroxypropyl) (2-hydroxyethyl) dimethylammonium chloride was added and stirred until uniform, and the temperature was raised to 85-95°C and stirred for 6.5-7.5 hours. After the reaction was completed, the product was allowed to stand for 50-60 minutes, and the product was vacuum filtered to obtain a residue. The residue was washed with 95% volume fraction ethanol solution until it was neutral, and finally the residue was dried to constant weight to obtain a stable flocculant.
