Description

Technical Field

[0001] The invention belongs to the technical field of functional daily chemical products, and particularly relates to a black hair care tea bran shampoo and a preparation method thereof. Background Art

[0002] Shampoo products mainly contain surfactants, which are one of the key ingredients of shampoo products. They have the ability to remove grease, dirt and residues on hair and scalp. As a daily chemical product used for a long time, people realize that shampoo contains more chemical ingredients, especially surfactants such as sodium lauryl sulfate, sodium laureth sulfate, and ammonium lauryl sulfate, which are highly irritating and easily lead to dry scalp. Therefore, mild natural plant active ingredients, silicone-free oil, and amino acid maintenance have become the development trend of shampoo. At present, a large number of plant ingredients have been used in shampoo, which is mild for shampooing and has a good effect on improving hair quality.

[0003] Tea bran is the residue after tea oil is extracted from tea seeds. It is rich in protein, tea polyphenols, and tea saponin, especially tea saponin, which has a content of more than 15% in tea bran. It is an excellent non-ionic natural surfactant with strong detergency. It can replace chemical surfactants in shampoo. It not only cleans gently, but also provides natural nourishment for hair and scalp.

[0004] But in fact, although tea bran contains rich nutrients and active ingredients, it is not suitable for direct use in shampooing. The main amino acids, tea polyphenols, and tea saponin active ingredients in tea bran are not easily leached due to the fastening of cellulose. The current methods of use are mainly grinding and soaking. Tea bran is ground into fine particles and easily remains on the hair and scalp, and the effective nutrients and active ingredients released are small, making it difficult to use in shampoo; tea bran is soaked and used, mainly through boiling and organic solvent soaking. The tea bran extracts prepared by these methods have the disadvantages of low active ingredient content and low effective utilization rate, and are difficult to concentrate and cannot be prepared into shampoo. Summary of the invention

[0005] The existing tea bran shampoo has the following problems: the effective ingredient extraction is limited, and the effect of the effective ingredient cannot be well exerted; the tea bran shampoo has a low concentration and is not delicate enough, which affects the use. In view of this, the present invention proposes a black hair care tea bran shampoo, the key technology of which is to extract the micro-fermentation liquid by micro-fermentation of tea bran, so that the effective ingredients of the tea bran are fully extracted and exert their effects. The obtained tea bran shampoo is non-irritating, has good decontamination and oil control effects, has obvious black hair and hair care effects, can significantly improve the scalp environment, and enhance hair nutrition; further, a preparation method of the black hair care tea bran shampoo is provided.

[0006] In order to achieve the above technical objectives, the present invention implements the following technical solutions:

[0007] Firstly, a black hair care tea bran shampoo is proposed, characterized in that the black hair care tea bran shampoo is composed of the following raw materials in parts by weight: 60-75 parts of deionized water, 10-15 parts of tea bran micro-fermentation liquid, 2-3 parts of black sesame extract, 3-5 parts of sodium cocoyl glutamate, 2-3 parts of sodium cocoyl glycinate, 1-2 parts of decyl glucoside, 1-3 parts of cocamide methyl MEA, 0.3-0.5 parts of hydroxyethyl cellulose, 0.1-0.3 parts of hydrolyzed oat protein, 0.1-0.2 parts of carbomer, 0.1-0.2 parts of tetrasodium glutamate diacetate, 0.1-0.2 parts of sodium chloride, 0.05-0.1 parts of phenoxyethanol, 0-1 parts of pH regulator, and 0-0.5 parts of flavor;

[0008] The tea bran micro-fermentation liquid is obtained by fermenting tea bran, yeast and cellulase at room temperature, and then undergoing steam explosion and cold pressing.

[0009] Preferably, the pH adjuster is selected from acidic adjusters such as citric acid, lactic acid, and glycolic acid according to needs; and the alkaline adjusters are sodium hydroxide and potassium hydroxide.

[0010] Preferably, the flavor is one or more of green apple flavor, lemon flavor, sweet lemon flavor, milk flavor, strawberry flavor, lily flavor, aloe flavor, white magnolia flavor, lavender flavor, jasmine white tea flavor, and orchid flavor.

[0011] Furthermore, a method for preparing the above-mentioned black hair care tea bran shampoo is proposed, and the specific preparation method is as follows:

[0012] S1: grind the tea bran through an 80-mesh sieve, mix and stir evenly with water in a mass ratio of 100:15-25, and steam for 30-60 minutes to obtain pretreated tea bran;

[0013] S2: naturally cool the tea bran pretreated in step S1, add yeast and cellulase and stir evenly, ferment in a sealed container at 30-35°C for 2-3h, heat to a pressure of 1.5MPa, maintain the pressure for 60s, then release the pressure and perform steam explosion treatment, send to a cold press for extrusion, filter and separate, and obtain tea bran fermentation liquid;

[0014] S3: According to the weight ratio, 0.3-0.5 parts of hydroxyethyl cellulose, 0.1-0.3 parts of hydrolyzed oat protein, and 0.1-0.2 parts of carbomer are added to 60-75 parts of deionized water, added to a stirring container, stirred at a low speed and soaked for 2-4 hours to obtain a uniform and delicate base liquid; 10-15 parts of tea bran micro-fermentation liquid, 2-3 parts of black sesame extract, 3-5 parts of sodium cocoyl glutamate, 2-3 parts of sodium cocoyl glycinate, and 1-2 parts of decyl glucoside are added to the base liquid, and stirred at a high speed in a vacuum degassing container for 10-15 minutes; then 1-3 parts of cocamide methyl MEA, 0.1-0.2 parts of tetrasodium glutamate diacetate, 0.1-0.2 parts of sodium chloride, 0.05-0.1 parts of phenoxyethanol, 0-1 parts of pH adjuster, and 0-0.5 parts of essence are added and stirred evenly at a low speed, filtered, sampled, and canned to obtain a black hair care tea bran shampoo.

[0015] Preferably, the amount of yeast in step S2 is 0.02-0.05% of the mass of the pretreated tea bran; the amount of cellulase is 0.01-0.05% of the mass of the pretreated tea bran; the yeast makes the tea bran fluffy, and the cellulase destroys and degrades the cellulose in the tea bran to a certain extent, which is conducive to the easy extrusion extraction of the effective ingredients in the tea bran.

[0016] Preferably, the low-speed stirring in step S3 is carried out at a rotation speed of 10-50 rpm, and the hydroxyethyl cellulose, hydrolyzed oat protein and carbomer are dissolved in deionized water to obtain a uniform and smooth base liquid.

[0017] Preferably, the high-speed stirring and homogenizing treatment in step S3 adopts high-speed stirring of 400-700 rpm.

[0018] Although tea bran has a good effect in shampooing, the traditional application of tea bran is mainly based on use after grinding, and the release of its active ingredients is extremely limited; furthermore, the method of boiling and leaching uses a large amount of water, making it difficult to obtain concentrated tea bran slurry.

[0019] The present invention hydrolyzes tea bran cellulose by micro-fermentation and cellulase, so that tea saponin, tea polyphenols, amino acids and other effective ingredients obtained from tea bran are easier to extract. In particular, after steam explosion and cold press extrusion, the effective ingredients in the obtained tea bran micro-fermentation liquid are concentrated and well retained, greatly improving the utilization rate of its nutritional components. Compared with directly grinding tea bran for use, the tea bran micro-fermentation liquid is more delicate and suitable for use in shampoo; compared with soaking tea bran for use, the tea bran micro-fermentation liquid is a concentrated liquid, retains more effective ingredients, has better nutritional effects, and is more suitable for direct use in shampoo systems.

[0020] The invention hydrolyzes tea bran cellulose by cellulase, so that tea saponin is well extracted, and the tea bran micro-fermentation liquid replaces a large amount of surfactants (such as sodium lauryl sulfate, sodium lauryl ether sulfate, ammonium lauryl sulfate, etc.) with strong degreasing property and strong irritation to the scalp in the shampoo. Furthermore, the black hair care tea bran shampoo of the invention has a significant hair care effect.

[0021] By using tea bran micro-fermentation liquid, the shampoo's rich amino acids provide nutrition to the hair, promote hair growth, and make the hair darker and brighter. Although tea bran micro-fermentation liquid cannot directly make hair darker, it nourishes the hair through tea polyphenols, amino acids, etc., and long-term use will significantly improve hair quality and make hair darker and brighter.

[0022] Furthermore, tea saponin in tea bran micro-fermentation liquid is a natural plant cleanser and also provides natural antibacterial effect, eliminating the need to add other preservatives to the shampoo formula system.

[0023] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows:

[0024] 1. The present invention hydrolyzes tea bran cellulose through micro-fermentation and cellulase, so that effective ingredients such as tea saponin, tea polyphenols, and amino acids obtained from the tea bran are easier to extract. In particular, after steam explosion and cold press extrusion, the effective ingredients in the obtained tea bran micro-fermentation liquid are concentrated. Compared with directly grinding the tea bran for use, the tea bran micro-fermentation liquid is more delicate and suitable for use in shampoo.

[0025] 2. The present invention allows tea saponin to be well extracted, and the tea bran micro-fermentation liquid can replace a large amount of surfactants with strong degreasing properties and strong irritation to the scalp in shampoo, and the rich amino acids provide nutrition for the hair, promote hair growth, and make the hair darker and brighter.

[0026] 3. The technology provided by the present invention is simple, the preparation process is simple and easy to control, and it is convenient for mass production. DETAILED DESCRIPTION
