Description

Technical Field

[0001] This invention relates to the field of hair strengthening and anti-hair loss products, specifically to a hair strengthening and anti-hair loss shampoo, its preparation method, and its application. Background Technology

[0002] With the improvement of people's living standards and the increasingly fast pace of life, hair loss problems caused by staying up late, high stress, and insomnia have become prominent. Shampoos that combine cleansing and hair-strengthening and anti-hair loss effects have become a research hotspot and a market necessity in the field of hair care.

[0003] Existing hair-strengthening and anti-hair loss shampoos can be formulated by adding compound plant extracts (CN115531243 B). However, there is still room for improvement in their hair-strengthening and anti-hair loss performance.

[0004] Based on this, the present invention designs a hair-strengthening and anti-hair loss shampoo, its preparation method and application to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a hair-strengthening and anti-hair loss shampoo, its preparation method and application.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A hair-strengthening and anti-hair loss shampoo comprises the following ingredients in parts by weight: 33-45 parts water; 22-41 parts of sodium C14-16 olefin sulfonate; 12-25 parts of cocamidopropyl betaine; Sodium lauroyl sarcosinate, 18-30 parts; 12-17 parts of sumac bark-silk co-extract; Sagein 1.5-3 parts; 1-6 parts of sodium methyl cocoyl taurate; 1-6 parts glycerin; 1-2 parts of phenoxyethanol; 1-2 parts of pyrrolidone ethanolamine salt; Polyquaternium-10 1-2 parts; 1-2 parts of disodium EDTA; The preparation method of the sumac bark-silk co-extract is as follows: first, sumac bark and silk are pretreated and weakly acidified with gluconolactone and succinic acid. Then, the acid-treated sumac bark / silk mixture is frozen at -20~-10℃ and ground into a mixed powder. The mixed powder is then subjected to supercritical fluid extraction and ultrasonic-assisted extraction in sequence.

[0007] Furthermore, the raw material pretreatment method is as follows: take dried sumac bark, crush it to 600-800 μm, and sieve it to remove impurities; select degummed silk and cut it to 0.5-1cm; mix them according to the mass ratio of sumac bark:silk = 2-3:1 to obtain mixed raw materials for later use.

[0008] Furthermore, the raw material weak acidification treatment method is as follows: Prepare the acid treatment solution: Weigh 6.0-7.5 parts by weight of gluconolactone and 4-4.5 parts by weight of succinic acid, mix them evenly, and then premix them with 10-11.5 parts by weight of propylene glycol to obtain a premixed slurry; Weigh 80-85 parts by weight of deionized water, heat it to 40-48℃, start stirring, and rotate at 600-800 rpm; Add the premixed slurry to the heated deionized water, and continue stirring for 20-28 minutes until the solution is completely clear and free of particles, and finally add 10% citric acid solution to adjust the pH to 4.0-4.5; According to the material-to-acid treatment solution ratio of 1:6-8, immerse the mixed raw materials in the acid treatment solution and stir at room temperature for 2-3 hours at a speed of 1000-1200 rpm; after filtration, drain and set aside the filter residue and the separated acid treatment solution.

[0009] Furthermore, the low-temperature freezing method is as follows: spread the filter residue evenly on a tray and freeze it at -20~-10℃ for 8-12 hours; after freezing, pulverize the material to 150-250 μm at a low temperature of -5~0℃ to obtain a mixed powder of sumac bark and silk.

[0010] Furthermore, the supercritical fluid extraction method involves loading the frozen sumac bark-silk mixed powder into a supercritical extraction vessel, using carbon dioxide as the extractant, and adding 5-8% anhydrous ethanol as an entrainer. The extraction parameters are: extraction pressure 28-30 MPa, extraction temperature 39-42℃, extraction time 2-3 h, CO2 flow rate 0.3-0.4 kg / h. The extract is collected, and the solid residue is dried for later use.

[0011] Furthermore, the ultrasonic-assisted extraction method is as follows: the solid residue after supercritical fluid extraction is added to the acid treatment solution separated in step (2) at a material-to-liquid ratio of 1:5~7, and transferred to an ultrasonic extraction tank; the ultrasonic power is set to 450-560W and the ultrasonic temperature to 48-50℃, and ultrasonic extraction is performed for 1-1.5h; the mixture is filtered and the ultrasonic extract is collected.

[0012] Furthermore, the extract was combined with the ultrasonic extract and concentrated under reduced pressure to 1 / 5-1 / 3 of the original volume. The concentrate was then freeze-dried to obtain a sumac bark-silk co-extract.

[0013] Furthermore, it also includes the following raw materials: 1-6 parts of PPG-3 octyl ether; 1-6 parts of cocamide methyl MEA; 1-2 parts flavoring; 1-2 parts sodium benzoate; Panthenol 1-2 parts; Guar gum hydroxypropyltrimethylammonium chloride 1-2 parts; Sodium chloride 1-2 parts.

[0014] To better achieve the objectives of this invention, this invention also provides a method for preparing a hair-strengthening and anti-hair loss shampoo, comprising the following steps: I. Preparation of Rhus chinensis bark-silk co-extract: First, Rhus chinensis bark and silk were pretreated and weakly acidified with gluconolactone and succinic acid. Then, the acid-treated Rhus chinensis bark / silk mixture was frozen at -20~-10℃ and ground into a mixed powder. The mixed powder was then subjected to supercritical fluid extraction and ultrasonic-assisted extraction in sequence. II. Weigh the raw materials according to the following parts by weight: water 33-45 parts; sodium C14-16 olefin sulfonate 22-41 parts; cocamidopropyl betaine 12-25 parts; sodium lauroyl sarcosinate 18-30 parts; sumac bark-silk co-extract 12-17 parts; oxalic acid 1.5-3 parts; sodium methyl cocoyl taurate 1-6 parts; glycerin 1-6 parts; phenoxyethanol 1-2 parts; piroctone ketone ethanolamine salt 1-2 parts; polyquaternium-10 1-2 parts; disodium EDTA 1-2 parts. 3. Mix the above ingredients evenly to obtain the hair-strengthening and anti-hair loss shampoo.

[0015] To better achieve the objectives of this invention, this invention also provides the application of the hair-strengthening and anti-hair loss shampoo in the preparation of hair-strengthening and anti-hair loss daily necessities or pharmaceuticals.

[0016] Compared to existing technologies, the beneficial effects of this invention are as follows: This invention adds ingredients such as a sumac bark-silk co-extract. Sumac bark contains polyphenols and flavonoids, which can effectively remove free radicals from the scalp, inhibit the release of inflammatory factors, and alleviate oxidative stress damage to the scalp caused by staying up late, high stress, and insomnia. Silk micropeptides can penetrate to the hair follicle roots, replenishing the amino acid nutrients needed for hair growth and forming a protective film on the hair surface. Sagein has excellent antioxidant capabilities, protecting hair follicle cells from oxidative damage and delaying hair follicle aging. Experimental testing shows that this invention has excellent hair-strengthening and anti-hair loss effects. Detailed Implementation
