Description

Technical Field

[0001] The invention relates to the technical field of fine chemicals, in particular to a natural plant hair dye oil and a preparation method thereof. Background Art

[0002] As people's living standards improve, they have a higher pursuit of appearance modification, and hair dyeing is one of the conventional ways of makeup. On the one hand, hair dyeing can modify white hair caused by genetics, disease, nutrition, aging and other reasons, making people look younger; on the other hand, hair dyeing has become a means for modern young people to pursue fashion. Most of the chemical hair dyes sold on the market now contain substances such as phenylenediamine, resorcinol, and ammonium hydroxide. Among them, phenylenediamine is a Class III carcinogen identified by the International Agency for Research on Cancer, resorcinol can cause respiratory diseases, and ammonium hydroxide is sensitizing. Studies have shown that long-term use of chemical hair dyes will increase the incidence of breast cancer, skin cancer, leukemia, and bladder cancer, and even a few people will experience anaphylactic shock and lead to life-threatening. Therefore, as people's awareness of health, safety and environmental protection increases, natural hair dye oil extracted from natural plants is the best choice.

[0003] Plant hair dye refers to a substance that uses pigments extracted from the flowers, stems, leaves and roots of plants to dye hair. From the perspective of health and safety, natural plant hair dye is basically safe for the human body and will not cause primary irritation. It not only maintains the original fresh ingredients of herbal essences, but also can repair the same color of faded hair after color dyeing, and can form a strong protective film on the hair, which has a good repair effect on damaged hair, making the hair more natural, stronger and more lustrous.

[0004] Prior art includes multiple natural plant hair dyes, such as China invention patent discloses CN102000017A discloses a black hair cream of Japanese blueberry plant, after using this black hair cream for hair dyeing, hair is black and shiny, natural color, and does not fade in three months, including Japanese blueberry leaf extract, saffron extract, madder extract, gallnut extract, oak extract, rhodiola rosea extract, ganoderma lucidum extract and hops extract. Another example China invention patent discloses CN102871927A discloses a natural hair dye, and its main raw materials are Japanese blueberry leaf, yam fruit, black rice and black sesame. Another example CN107753355A discloses a preparation method of a natural hair dye, and the raw materials of its hair dye include Polygonum multiflorum extract, Japanese blueberry extract, also include stabilizer EDTA and stearic acid and auxiliary agent glycerol and dimethicone.

[0005] The above-mentioned hair dyes all use extracts of the leaves of the Japanese rice tree. Although the leaves of the Japanese rice tree are promoted as a natural and safe choice, in actual use, some users still report that the hair dyeing effect is not ideal, and a double-type agent must be used when using it, and the hair dyeing is accompanied by an ammonia smell and a tingling sensation on the scalp.

[0006] The prior art is in urgent need of a natural plant hair dye that does not contain ingredients such as phenylenediamines, resorcinol, ammonium hydroxide, and blueberry leaf extract, and has no ammonia odor and scalp tingling sensation. Summary of the invention

[0007] In order to solve the above problems, the present invention provides a natural plant hair dye oil, which is prepared from natural plant extracts such as Polygonum multiflorum, Astragalus, Ganoderma lucidum, etc., and does not contain ingredients such as phenylenediamines, resorcinol, ammonium hydroxide, and blueberry leaf extract. It has outstanding hair dyeing effect and is safe and non-irritating.

[0008] According to one aspect of the present invention, a natural plant hair dye is provided, comprising bean extract, ganoderma lucidum extract, astragalus extract, Polygonum multiflorum extract, and plant oils and fats, characterized in that it also contains the following active ingredients extracted from natural plants: erythritol, L-proline, ferulic acid, and 4-aminobutyric acid.

[0009] Preferably, a small amount of sebacic acid is also contained to serve as a preservative for the hair dye oil.

[0010] In the present invention, the sebacic acid is food grade, preferably obtained by thermal cracking of ricinoleic acid, and is commonly used as a preservative in the food industry to preserve food. It can also increase the taste of food. In the present invention, it is used to extend the shelf life of hair dye.

[0011] Preferably, a small amount of propylene glycol is also contained, which serves as a moisturizer and solvent for the hair dye oil.

[0012] In the present invention, propylene glycol is of food grade and is commonly used in the food industry to maintain moisture in food, prevent food from drying and changing, help dissolve certain food ingredients, such as pigments, spices, etc., and prevent food from crystallizing and destroying its tissue structure during the freezing process. In the present invention, the propylene glycol is also used as a humectant, solubilizer, and antifreeze agent for hair dye to maintain moisture.

[0013] Preferably, the mass percentages of the bean extract, ganoderma lucidum extract, astragalus extract, polygonum multiflorum extract, vegetable oil, erythritol, L-proline, ferulic acid, and γ-aminobutyric acid are (10-30): (1-5): (1-5): (10-30): (50-70): (1-5): (1-5): (1-5): (1-5): (1-5).

[0014] Preferably, the mass percentage of the bean extract, ganoderma lucidum extract, astragalus extract, polygonum multiflorum extract, vegetable oil, erythritol, L-proline, ferulic acid and γ-aminobutyric acid is 10:5:5:10:50:5:5:5:5.

[0015] Preferably, the bean extract, ganoderma lucidum extract, astragalus extract, polygonum multiflorum extract, vegetable oil, erythritol, L-proline, ferulic acid, sebacic acid, γ-aminobutyric acid, and propylene glycol account for a total of 38% (wt) of the hair dye, and the remainder is pure water.

[0016] Preferably, all extracts, plant oils and active ingredients contained in the hair dye are from the following 23 materials: black rice, black beans, black sesame, rice, walnuts, yam, honey, edible oil, edible flavors, black barley, black buckwheat, black mulberry, erythritol (Erythritol, one or more of grapes, melons, mushrooms, etc. can be used), osmanthus, wild ganoderma, Panax notoginseng, Gastrodia elata, deer antler, astragalus, licorice, Polygonum multiflorum, star anise, and chia seeds.

[0017] Preferably, the active ingredients of the bean extract include soy isoflavones.

[0018] Preferably, the Ganoderma lucidum extract comprises ganoderic acid B and ganoderiol A.

[0019] Preferably, the active ingredient of the astragalus extract includes astragaloside (7,2'-dihydroxy-3',4'-dimethoxyisoflavane-7-O-glucoside).

[0020] Preferably, the Polygonum multiflorum extract is a Polygonum multiflorum root extract, comprising stilbene glycoside / 2,3,5,4-tetrahydroxystilbene-2-O-β-D-glucoside as an active ingredient.

[0021] Preferably, the active ingredients extracted from natural plants in the hair dye oil also include one or more active ingredients of chamomile (Chamomillarecutita) flower extract, azadirachtin (azadirachtin), sapindusmukorossi (Sapindusmukorossi) peel extract, licorice (Glycyrrhiza uralensis) root extract, Platycladus orientalis (Biota orientalis) leaf extract, ginseng (Panax ginseng) root extract, and Cordyceps sinensis.

[0022] Preferably, the active ingredients extracted from natural plants also include 5,6,7,3',4',5'-hexamethoxyflavanone and 2'-hydroxy-2,4,4',5,6'-pentamethoxychalcone (Rubone).

[0023] According to the present invention, the hair dye oil ingredients all come from natural plants (various extracts, oils, and active ingredients) or the main reaction precursor ingredients come from natural plants (sebacic acid, propylene glycol), so it is safe for most people when using the hair dye oil of the present invention to dye hair. If the hair dye oil is used alone for hair dyeing, by statistics of 100 hair dyers with white or gray hair, 80% of the hair dyers need about 90 minutes for all the hair to turn black, and 20% of the hair dyers need about 200 minutes for all the hair to turn black, and no scalp and skin allergies occur. This is a long time for many hair dyers, but for health, this time is still acceptable. By statistics of 100 hair dyers with dry, split, and yellow hair, 99% of the hair dyers' hair obviously becomes black and shiny after 90 minutes of hair dyeing, and only one hair dyer has a slightly poor blackening effect. This situation is being studied by the team of the present invention, which may be related to the weak constitution of the hair dyer. Through long-term follow-up investigation of the 200 hair dyers, no case showed obvious hair loss. Although many pregnant volunteers actively signed up to try to use it, they were rejected by the research and development team. The hair dye oil of the present invention is suitable for pregnant women in principle, but pregnant women are still refused to use it, so there is no case of pregnant women using it for the time being.

[0024] In the present invention, in order to shorten the hair dyeing time, a B-type agent can also be used in combination. The B-type agent preferably uses hydrogen peroxide and salicylic acid. According to the research results of the present invention team, by adding 18% (wt) of the B-type agent to the hair dye oil of the present invention, the hair dyeing time can be greatly reduced to less than 15 minutes. The more the proportion added, the shorter the hair dyeing time, but the more it deviates from the spirit of the present invention, because the excessive amount of the B-type agent used will cause hair damage. When the amount of the B-type agent added is reduced to 9% (wt), the hair dyeing effect is almost the same as that without adding the B-type agent, that is, the factors that promote the opening of the hair scales will be dominated by natural plant active ingredients, and the black dyeing time will suddenly increase to about 90 minutes. Since the B-type agent used in the present invention does not have a bad irritating odor such as ammonia odor, the hair dye oil will emit a plant fragrance when dyeing hair, giving people a refreshing feeling. Through statistics of 100 hair dyers (generally aged 40-50 years old) who added 18% (wt) B-type agent, it was found that the dyeing time was in the range of 8-15 minutes, and no skin allergy and scalp irritation occurred. Through statistics of 100 hair dyers (generally aged 60-90 years old) who added 9% (wt) B-type agent, it was found that the dyeing time was about 90 minutes, and no skin allergy and scalp irritation occurred. Even if an appropriate amount of B-type agent is added to the hair dye oil of the present invention, it shows a very friendly result for hair dyers.

[0025] Preferably, in the process of using the hair dye oil for hair dyeing, salicylic acid is used as a stabilizer in combination with the hair dye oil. Salicylic acid is o-hydroxybenzoic acid, with a chemical formula of C7H6O3, and has antioxidant and antibacterial properties. It can exfoliate, promote the shedding of aged stratum corneum, and also have antibacterial and anti-inflammatory properties.

[0026] Preferably, in the process of dyeing hair with the hair dye, hydrogen peroxide is used as an oxidant. Hydrogen peroxide mainly contains hydrogen peroxide (H2O2) and stabilizers. When dyeing hair, hydrogen peroxide is mixed with the hair dye to open the hair scales, allowing the hair dye to enter the hair and oxidize and develop color. In the process of bleaching hair, natural pigments in the hair can also be removed. As an oxidant, urea peroxide, peroxy salt, etc. can also be used.

[0027] In the present invention, since pure natural plants such as Platycladus orientalis leaf extract, ginseng root extract, Polygonum multiflorum root extract, etc. are used as hair care ingredients, the pH value of the hair dye formed after synthesis is almost close to a neutral level, which is relatively gentle to human sensory stimulation, so there is no need to use an additional pH regulator.

[0028] In the present invention, beans, plant oils and the like are used as the blending ingredients, so a plant fragrance is formed after synthesis, and no conditioning agent is needed for conditioning.

[0029] In the present invention, since the components have good affinity with the human body and can be placed in the air for more than 4 hours without being oxidized, which is enough time for hair dyeing operation, there is no need to use various antioxidants and anti-ascorbic ingredients.

[0030] In the present invention, in order to cooperate with the use of hair dye, salicylic acid is used as a stabilizer and hydrogen peroxide is used as an oxidant to cooperate with the use of the hair dye in the process of using the hair dye. It should be pointed out that if hydrogen peroxide and / or salicylic acid are used, a skin allergy test is required in advance. If you have an allergic constitution, it is not recommended to use the type B agent.

[0031] In the present invention, although the example of dyeing white hair or gray hair black is used, if dyeing is done to other colors, some plant pigments can be added to the hair dye oil of the present invention, and a pH adjuster can be added if necessary to obtain the desired color.

[0032] For hair dyes, hair dyeing effect and scalp irritation are important indicators to consider. The degree of dye penetration into the hair is the key to determining the long-term retention of hair color. If the pigment only stays on the surface of the hair, it will easily fade away when washing the hair. In the prior art, a large amount of oxidants or alkalizers are usually added to promote the dye to penetrate into the hair before the reaction. However, oxidants or alkalizers are very irritating to the scalp, which is also one of the important factors that normal people cannot tolerate hair dyeing. For the hair dye of the present invention, due to the use of the above-mentioned extracts, natural plant active ingredients, plant oils and the like, it is possible to promote the penetration of natural pigments into the hair when a small amount of oxidant (hydrogen peroxide) is used or even when no oxidant is used. After hundreds of hair dyeing comparisons, it is found that the use of a small amount of hydrogen peroxide and salicylic acid mixture can shorten the hair dyeing time, and the hair dyeing effect is slightly longer than that of not using the retention dyeing time. The hair dye provided by the present invention does not contain chemical components at all, and some of the natural plant active ingredients, extracts and plant oil components therein provide the necessary plant proteins, polysaccharides, vitamins and unsaturated fatty acids for the hair, etc., which can penetrate into the hair together with the plant dyes and pigments when the hair scales are opened, so that the hair slowly turns black. The bean extract, ganoderma lucidum extract, astragalus extract, Polygonum multiflorum extract and the like are compounded as plant dyes to dye and fix the color, and the plant oils and the like, erythritol, L-proline, ferulic acid, γ-aminobutyric acid and the like can be used as penetration media to promote the opening of the hair scales and promote the hair to absorb the plant dyes. It should be pointed out that although the present invention is used for hair dyeing, the effective ingredients obviously include beneficial ingredients that promote the synthesis of melanin. Whether melanin is synthesized in the process of hair dyeing remains to be verified in subsequent research and development. The dyeing effect of the hair dye oil of the present invention can be retained for 2 to 3 months. The effective active ingredients of the hair dye oil of the present invention promote the opening of the hair scales, but do not cause substantial damage to the hair, so no hair loss is found in practice. On the contrary, by opening the hair scales, not only plant pigments but also nutrients required by the hair are brought in, which essentially can also achieve the care of the hair at the same time.

[0033] The hair dye of the present invention is not limited to being made into a liquid oil, and can also be made into a paste, emulsion, cream, mucus, etc. that are suitable for stirring and mixing. Even, some ingredients are made into liquid oil, and some are ground into powder. For example, osmanthus, wild ganoderma, Panax notoginseng, Gastrodia elata, antler, astragalus, licorice, Polygonum multiflorum, star anise, chia seeds, etc. are ground into powder and mixed into bottles for use. In one embodiment of the present invention, among the above 23 ingredients, the edible flavor is a powdered edible flavor, and except for honey and edible oil, the other ingredients are ground into powder for use.

[0034] According to another aspect of the present invention, there is also provided a method for preparing a natural plant hair dye oil, comprising the following steps:

[0035] The steps of preparing bean extract, ganoderma lucidum extract, astragalus extract and polygonum multiflorum extract are as follows: grinding and crushing dried beans and other raw materials, sieving, dissolving the obtained bean powder in a 50% propylene glycol aqueous solution in an ultrasonic extractor for extraction, vacuum filtering and vacuum concentrating the obtained extract to obtain the bean extract, and then mixing the extracts in a certain proportion to obtain extract powder, and canning for later use;

[0058] The present invention is described in detail below in conjunction with specific embodiments. It should be understood by those skilled in the art that these embodiments are illustrative only and not restrictive. The various means used in the present invention, such as extraction means, heating means, stirring means, etc., are all conventional means, and the raw materials, reagents, etc. used can be obtained from supermarkets or conventional channels. Although the hair dye of the present invention is described in terms of dyeing hair black, it is obvious that various improvements can be made on this basis to dye hair into colors such as gold, brown, and coffee.

[0059] The natural plant hair dye oil of the present invention can be made into finished products, and different styles can be designed according to different scenes, so that it is convenient for hair dyers to choose to buy and use by themselves, and it can also be designed into semi-finished products, so that buyers can experience the fun of DIY. The core components of the natural plant hair dye oil of the present invention include bean extract, ganoderma lucidum extract, astragalus extract, Polygonum multiflorum extract, plant oil, and the following active ingredients extracted from natural plants: erythritol (Erythritol), L-proline (L-proline), ferulic acid (ferulic acid), γ-aminobutyric acid (4-aminobutyric acid). These extracts, plant oils, and active ingredients all come from the following 23 materials: black rice, black beans, black sesame, rice, walnuts, Chinese yam, honey, edible oil, edible flavors, black barley, black buckwheat, black mulberries, erythritol (Erythritol, grapes, melons, mushrooms, etc. One or more can be used), osmanthus, wild ganoderma lucidum, Panax notoginseng, Gastrodia elata, deer antler, astragalus, licorice, Polygonum multiflorum, star anise, chia seeds. In these compositions, preferably adopt fresh raw material, such as the honey just brewed, the edible oil just refined or the like. In these natural plant ingredients, some need its shell, such as walnut, some need its rhizome, such as Polygonum multiflorum or the like. In hair dye of the present invention, also there will be a small amount of sebacic acid (sebacic acid), propylene glycol (Propylene glycol) or the like, on the one hand, they all adopt food grade, on the other hand, when extracting, a small amount of extract can be left, which is also just required composition. Except sebacic acid, in this hair dye, can also add Platycladus orientalis (biota orientalis) leaf extract and use as preservative jointly, even as finished product hair dye, it can also prolong the shelf life of hair dye. In the present invention, propylene glycol is used for the effect of humectant, solubilizer, antifreeze that hair dye keeps moisture.

[0060] The mass percentages of bean extract, ganoderma lucidum extract, astragalus extract, polygonum multiflorum extract, vegetable oil, erythritol, L-proline, ferulic acid, and gamma-aminobutyric acid are (10-30): (1-5): (1-5): (10-30): (50-70): (1-5): (1-5): (1-5): (1-5). Adding a small amount of sebacic acid and propylene glycol, the total mass percentage of these ingredients in the hair dye oil is 38% (wt), and the balance is pure water.

[0061] In a preferred embodiment of the present invention, the active ingredients extracted from natural plants in the hair dye oil also include one or more active ingredients in chamomile (Chamomillarecutita) flower extract, azadirachtin (azadirachtin), sapindus mukorossi (Sapindusmukorossi) peel extract, licorice (Glycyrrhiza uralensis) root extract, Platycladus orientalis (Biota orientalis) leaf extract, ginseng (Panax ginseng) root extract, and Cordyceps sinensis. Adding these extracts can provide better nutrients to the hair, promote the opening of the hair scales, and prevent the hair from withering, splitting, and falling.

[0062] Figure 1 and Figure 2 They are respectively an LC-MS test detection graph (POS) and an LC-MS test detection graph (NEG) of a natural plant hair dye oil component according to one embodiment of the present invention.

[0063] like Figure 1 and 2 As shown, the test results show that in the hair dye of the present invention, the bean extract active ingredients include soybean isoflavone (Isoflavone), the ganoderma lucidum extract includes ganoderic acid B (ganoderic acid B) and ganoderiol A (ganoderiol A), the astragalus extract active ingredients include astragalus isoflavan glycosides (7,2'-dihydroxy-3',4'-dimethoxyisoflavane-7-O-glucoside), and the Polygonum multiflorum extract includes stilbene glycoside / 2,3,5,4-tetrahydroxystilbene-2-O-β-D-glucoside (2,3,5,4'-Tetrahydroxystilbene-2-O-β-D-glucoside) active ingredients. Active ingredients extracted from natural plants also include erythritol (Erythritol), L-proline (L-proline), ferulic acid (ferulic acid), γ-aminobutyric acid (4-aminobutyric acid) and the like. In a preferred embodiment, the active ingredients extracted from natural plants also include 5,6,7,3',4',5'-hexamethoxyflavanone, azadirachtin, 2'-hydroxy-2,4,4',5,6'-pentamethoxychalcone (Rubone) and the like.

[0064] Figure 3 This is a graph showing the test results of a natural plant hair dye oil according to the "Technical Specifications for Safety of Cosmetics" involved in one embodiment of the present invention.

[0065] like Figure 3 As shown, the total number of colonies, total number of molds and yeasts, heat-resistant coliform group, Staphylococcus aureus and Pseudomonas aeruginosa of the hair dye of the present invention all meet the safety requirements of relevant specifications.

[0066] In a preferred embodiment of the present invention, in order to shorten the hair dyeing time, a B-type agent can also be used in combination. The B-type agent preferably uses hydrogen peroxide and salicylic acid. According to the research results of the present invention team, by adding 18% (wt) of the B-type agent to the hair dye oil of the present invention, the hair dyeing time can be greatly reduced to less than 15 minutes. The more the proportion added, the shorter the hair dyeing time, but the more it deviates from the spirit of the present invention, because the excessive amount of the B-type agent used will cause hair damage. When the amount of the B-type agent added is reduced to 9% (wt), the hair dyeing effect is almost the same as that without adding the B-type agent, that is, the factors that promote the opening of the hair scales will be dominated by natural plant active ingredients, and the black dyeing time will suddenly increase to about 90 minutes. Since the B-type agent used in the present invention does not have a bad irritating odor such as ammonia odor, the hair dye oil will emit a plant fragrance when dyeing hair, giving people a refreshing feeling. Through statistics of 100 hair dyers (generally aged 40-50 years old) who added 18% (wt) B-type agent, it was found that the dyeing time was in the range of 8-15 minutes, and no skin allergy and scalp irritation occurred. Through statistics of 100 hair dyers (generally aged 60-90 years old) who added 9% (wt) B-type agent, it was found that the dyeing time was about 90 minutes, and no skin allergy and scalp irritation occurred. Even if an appropriate amount of B-type agent is added to the hair dye oil of the present invention, it shows a very friendly result for hair dyers.

[0067] In a preferred embodiment of the present invention, since pure natural plants such as Platycladus orientalis leaf extract, Panax ginseng root extract, Polygonum multiflorum root extract, etc. are used as hair care ingredients, the pH value of the hair dye formed after synthesis is almost close to a neutral level, which is relatively gentle to human sensory stimulation, so there is no need to use an additional pH regulator.

[0068] In the present invention, beans, plant oils and the like are used as the blending ingredients, so a plant fragrance is formed after synthesis, and no conditioning agent is needed for conditioning.

[0069] In the present invention, since the components have good affinity with the human body and can be placed in the air for more than 4 hours without being oxidized, which is enough time for hair dyeing operation, there is no need to use various antioxidants and anti-ascorbic ingredients.

[0070] In the present invention, although the example of dyeing white hair or gray hair black is used, if dyeing is done to other colors, some plant pigments can be added to the hair dye oil of the present invention, and a pH adjuster can be added if necessary to obtain the desired color.
