Description

Technical Field

[0001] The present invention relates to the technical field of fine chemicals, and particularly to a natural plant hair dye and a method for producing the same.

Background Art

[0002] With the improvement of people's living standards, the requirements for appearance decoration have increased, and hair dyeing is one of the common makeup methods. On the one hand, hair dyeing can hide white hair caused by reasons such as genetics, illness, nutrition, and aging, and can give a youthful impression. On the other hand, hair dyeing has become one of the means for modern young people to pursue fashion. Currently, most commercially available chemical hair dyes contain substances such as phenylenediamines, resorcinol, and ammonium hydroxide. Phenylenediamine is a category 3 carcinogen clearly classified by the International Agency for Research on Cancer, resorcinol can cause respiratory diseases, and ammonium hydroxide may cause allergic reactions. According to research, long-term use of chemical hair dyes can increase the incidence of breast cancer, skin cancer, leukemia, and bladder cancer, and furthermore, a small number of people may experience anaphylactic shock and be at risk of life. Therefore, with the increasing awareness of health and safety and environmental protection, natural hair dyes extracted from natural plants are the best choice.

[0003] A plant hair dye is a substance that dyes hair using pigments extracted from the flowers, stems, leaves, and roots of plants. Natural plant hair dyes are generally safe for the human body and do not cause primary irritation in terms of health and safety. They not only retain the original active ingredients of herbal essences but can also repair faded hair in the same color after dyeing, and can form a strong protective film on the hair, repair damaged hair quality, and make the hair more natural, strong, and shiny.

[0004] Conventional technologies include various natural plant-based hair dyes. A Chinese invention patent (publication number: CN102000017A) discloses a blueberry plant-based black dye cream. After dyeing hair with this black dye cream, the hair becomes dark and glossy, the color is natural, and the color does not fade for three months. This black dye cream contains blueberry leaf extract, safflower extract, lilac extract, oak extract, sawtooth oak extract, cinnamon extract, reishi mushroom extract, and hop extract. Another Chinese invention patent (publication number: CN102871927A) discloses a natural hair dye whose main raw materials are blueberry leaves, yam fruit, black rice, and black sesame. Furthermore, CN107753355A discloses a method for manufacturing a natural hair dye, and the raw materials for manufacturing the hair dye include cashew extract and blueberry extract, and also include EDTA and stearic acid as stabilizers, and glycerin and dimethicone as auxiliary agents. All of the above hair dyes use blueberry leaf extract. While blueberry leaf is advertised as a natural and safe choice, there has been feedback from users that the dyeing effect is insufficient during actual use. Therefore, it is necessary to use two hair dyes in combination, and the dyeing process may be accompanied by an ammonia odor and a tingling sensation on the scalp. Conventional technologies require a natural plant-based hair dye that does not contain ingredients such as phenylenediamines, resorcinol, ammonium hydroxide, or blueberry leaf extract, and does not produce an ammonia odor or cause a tingling sensation on the scalp. [Overview of the project] [Problems that the invention aims to solve]

[0005] To solve the above problems, the present invention provides a natural plant-based hair dye that is manufactured using natural plant extracts such as Polygonum multiflorum, Astragalus membranaceus, and Ganoderma lucidum, and does not contain any ingredients such as phenylenediamines, resorcinol, ammonium hydroxide, or blueberry leaf extract, and has good hair dyeing effect, is safe and non-irritating. [Means for solving the problem]

[0006] According to one aspect of the present invention, a natural plant hair dye is provided, comprising a legume extract, a reishi mushroom extract, an astragalus extract, a Polygonum multiflorum extract, and a vegetable oil, further comprising active ingredients such as erythritol, L-proline, ferulic acid, and 4-aminobutyric acid extracted from natural plants. Preferably, it further contains a small amount of sebacic acid and is used as a preservative for the hair dye. In the present invention, the sebacic acid is food-grade and is obtained by preferentially thermally decomposing ricinoleic acid. It is commonly used in the food industry as a food preservative and has the effect of improving the flavor of food. In the present invention, it extends the shelf life of hair dyes. Preferably, it further contains a small amount of propylene glycol, which is used as a humectant and solvent for the hair dye. In the present invention, propylene glycol is of food grade and is selected to help retain moisture in food in the food industry, prevent food from drying out and hardening, dissolve certain food components such as pigments and flavors, and prevent crystallization and destruction of the tissue structure of food during the freezing process. In the present invention, it is used as a humectant, solvent, and antifreeze to retain moisture in hair dyes.

[0007] Preferably, the mass percentages of the legume extract, reishi mushroom 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). Preferably, the mass percentages of the legume extract, reishi mushroom extract, astragalus extract, Polygonum multiflorum extract, vegetable oil, erythritol, L-proline, ferulic acid, and γ-aminobutyric acid are 10:5:5:10:50:5:5:5:5.

[0008] Preferably, the total mass percentage of the legume extract, reishi mushroom extract, astragalus extract, Polygonum multiflorum extract, vegetable oil, erythritol, L-proline, ferulic acid, sebacic acid, γ-aminobutyric acid, and propylene glycol in the hair dye is 38% (wt), with the remainder being pure water.

[0009] Preferably, all extracts, vegetable oils, and active ingredients contained in the hair dye are derived from 23 different materials, including black rice, black beans, black sesame, rice, walnuts, senna, honey, edible oil, edible essence, black hulless barley, black buckwheat, black ginseng, erythritol (one or more types of erythritol such as grape, melon, or mushroom can be used), osmanthus flower, wild lychee, sanshichi, tama, rokuden, astragalus, licorice, kashu, star anise, and chia seeds. Preferably, the active ingredient of the legume extract contains soy isoflavone. Preferably, the reishi extract contains ganoderic acid B and ganoderiol A.

[0010] Preferably, the active ingredient of the Astragalus extract contains 7,2'-dihydroxy-3',4'-dimethoxyisoflavane-7-O-glucoside. Preferably, the Polygonum multiflorum extract is a Polygonum multiflorum root extract and contains an active ingredient such as stilbene glycoside / 2,3,5,4'-Tetrahydroxystilbene-2-O-β-D-glucoside.

[0011] Preferably, the active ingredients extracted from natural plants in the hair dye further include one or more active ingredients from among chamomile (chamomillarecutita) flower extract, azadirachtin, soapberry (sapindus mukorossi) fruit peel extract, licorice (glycyrrhizauralensis) root extract, broom leaf (biota orientalis) extract, ginseng (panaxginseng) root extract, and cordyceps. Preferably, the active ingredients extracted from natural plants further include 5,6,7,3',4',5'-Hexamethoxyflavanone and 2'-Hydroxy-2,4,4',5,6'-Pentamethoxychalcone (Rubone).

[0012] According to the present invention, all components of the hair dye are derived from natural plants (each extract, oil, and active ingredient), or the main reaction precursor components are derived from natural plants (sebacic acid, propylene glycol), making it safe for most people when dyeing their hair with the hair dye of the present invention. When the hair dye is used alone, statistics were obtained from 100 people with full heads of gray hair, and 80% of the dyers took about 90 minutes for their hair to become completely black, 20% took about 200 minutes, and there were no cases of allergic reactions to the scalp or skin. While this may seem like a long time to many dyers, it is within an acceptable range for health reasons. A statistical analysis of 100 individuals whose hair became dry, split, or yellowish after dyeing revealed that 99% of them had noticeably blacker and shinier hair after 90 minutes of dyeing. Only one individual showed a slightly less effective blackening effect. The team is continuously researching this situation and believes it may be related to the individual's weaker constitution. A long-term follow-up study of these 200 individuals showed no significant hair loss. Despite many pregnant volunteers actively requesting to try the product, the team has refused. Although the hair dye is generally safe for pregnant women, its use by pregnant women is currently prohibited, and therefore, there are no cases of pregnant women using it.

[0013] In this invention, the hair dye can also be used in combination with a type B agent to shorten the dyeing time. Preferably, hydrogen peroxide emulsion or salicylic acid is used as the type B agent. According to the research results of the team of this invention, adding 18% (wt) of type B agent to the hair dye of this invention can significantly shorten the dyeing time to within 15 minutes. The dyeing time will be shortened as the proportion of type B agent added increases, but this will deviate from the spirit of this invention, as using too much type B agent may damage the hair. When the amount of type B agent added is reduced to 9% (wt), the dyeing effect is almost the same as when no type B agent is added. In other words, the factors that promote cuticle opening are dominated by natural plant-derived active ingredients, and the black dyeing time increases sharply to about 90 minutes. The type B agent used in this invention does not have an unpleasant irritating odor such as ammonia odor, so when dyeing hair, the hair dye emits a refreshing plant-derived fragrance and provides a pleasant cooling sensation. Statistical analysis of 100 hair dyers (typically aged 40-50) who added 18% (wt) of type B agent showed that the dyeing time was in the range of 8-15 minutes, and no cases of skin allergy or scalp irritation were observed. Statistical analysis of 100 hair dyers (typically aged 60-90) who added 9% (wt) of type B agent showed that the dyeing time was approximately 90 minutes, and no cases of skin allergy or scalp irritation were observed. The hair dye of the present invention shows very favorable results for hair dyers even when an appropriate amount of type B agent is added.

[0014] Preferably, in the process of dyeing hair using the hair dye, salicylic acid is used in combination with the hair dye as a stabilizer. The salicylic acid component is methyl salicylate, which has the chemical formula C7H6O3 and possesses antioxidant and antibacterial properties, removes dead skin cells, makes it easier to peel off aged keratinized layers, and also has antibacterial and anti-inflammatory effects.

[0015] Preferably, in the process of dyeing hair using the hair dye, a hydrogen peroxide emulsion is used in combination with the hair dye as an oxidizing agent. The hydrogen peroxide emulsion mainly contains hydrogen peroxide (H2O2) and stabilizers. By mixing the hydrogen peroxide emulsion with the hair dye during dyeing, the hair cuticles are opened, the hair dye can penetrate into the hair and develop color through an oxidation reaction, and the natural pigments of the hair can also be removed during the bleaching process. Examples of oxidizing agents that can be used include urea peroxide and peroxide salts. In this invention, since pure natural plant components such as mole mulberry extract, carrot root extract, and Polygonum multiflorum root extract are used as hair care components, the pH value of the synthesized hair dye is close to neutral, and the sensory irritation to people is mild, so there is no need to use a separate pH adjuster. In this invention, since compounding components such as legumes and vegetable oils are used, the resulting product has a refreshing plant-derived aroma and does not require adjustment with a conditioning agent.

[0016] In this invention, each component has good affinity with the human body and does not oxidize even after more than 4 hours in the air, ensuring sufficient time for the hair dyeing process. Therefore, there is no need to separately use various antioxidants and ascorbic acid components. In this invention, for use in combination with a hair dye, salicylic acid is used as a stabilizer and hydrogen peroxide emulsion as an oxidizing agent in the process of dyeing hair using the hair dye. Note that when using hydrogen peroxide emulsion and / or salicylic acid, a skin allergy test must be performed beforehand, and the use of the type B agent is not recommended for those with allergies. In this invention, we take dyeing white or gray hair black as an example, but if you want to dye it a different color, you can obtain the desired color by adding plant pigments to the hair dye of this invention and, if necessary, adding a pH adjuster.

[0017] For hair dyes, coloring effectiveness and scalp irritation are important indicators for evaluating them. How deeply the dye penetrates the hair is key to maintaining the color for a long time. If the pigment only remains on the surface of the hair, the color will easily wash out. Conventional techniques often involve adding large amounts of oxidizing or alkalizing agents to promote penetration into the hair before the dye can react. However, oxidizing and alkalizing agents are highly irritating to the scalp, which is another important factor that makes it difficult for most people to tolerate hair dyeing. The hair dye of the present invention, by using the above-mentioned extracts, natural plant active ingredients, and plant oils, can penetrate natural pigments into the hair even with the use of a small amount of oxidizing agent (hydrogen peroxide emulsion) or without the use of an oxidizing agent. As can be seen from comparisons of hundreds of hair dyeing cases, using a mixture of a small amount of hydrogen peroxide emulsion and salicylic acid can shorten the hair dyeing time, and the dyeing effect has a slightly longer retention time compared to when it is not used. The hair dye of the present invention contains no chemical components at all, and some of the natural plant active ingredients, extracts, and plant oil components provide plant proteins, polysaccharides, vitamins, and unsaturated fatty acids necessary for hair, which penetrate into the hair along with plant dyes and pigments when the hair cuticle is opened, and the hair can be gradually made black. When the aforementioned legume extracts, reishi mushroom extracts, astragalus extracts, and Polygonum multiflorum extracts are incorporated as plant dyes, the hair can be dyed and the color can be retained. The aforementioned plant oils, erythritol, L-proline, ferulic acid, and γ-aminobutyric acid can be used as penetration media to promote the opening of the hair cuticle and promote the absorption of plant dyes into the hair. Although the present invention is used for hair dyeing, the active ingredients clearly contain beneficial components that promote melanin synthesis. Whether or not melanin is synthesized during the hair dyeing process should be verified in future research and development. The dyeing effect of the hair dye of the present invention can be maintained for 2 to 3 months. The effective active ingredients of the hair dye of the present invention promote the opening of the hair cuticle, but do not cause substantial damage to the hair. In fact, hair loss is not observed. Moreover, by opening the cuticle, not only plant pigments but also necessary nutrients for the hair can be introduced, essentially achieving hair care.

[0018] The hair dye of the present invention is not limited to being manufactured in liquid oil form, but may also be manufactured in a form suitable for stirring and mixing, such as paste, milky, creamy, or viscous form. Furthermore, some components may be manufactured in liquid oil form, and some may be pulverized into powder form. For example, osmanthus flowers, wild lychee, sanshichi, doma, rokujo, astragalus, licorice, kashu, star anise, chia seeds, etc., may be pulverized into powder form, mixed, bottled, and prepared for use. In one embodiment of the present invention, of the above 23 components, powdered edible essence is used for the edible essence, and all components except honey and edible oil are pulverized into powder form and prepared for use.

[Figure 2] This is an LC-MS test detection graph (NEG) of the components of a natural plant hair dye according to one embodiment of the present invention, with the horizontal axis representing time (seconds) and the vertical axis representing relative abundance. [Figure 3] This is a diagram showing the detection results of a natural plant hair dye according to one embodiment of the present invention, based on the "Cosmetic Safety Technical Specifications". [Modes for carrying out the invention]

[0028] The present invention will be described in detail below with reference to specific examples. Those skilled in the art will understand that these examples are merely illustrative and not limiting. The various means used in the present invention, such as extraction, heating, and stirring, are all common methods, and the raw materials and reagents used are all readily available at supermarkets or through conventional channels. The hair dye of the present invention is described as a dye that colors hair black, but naturally, with various modifications, it can also be used to dye hair gold, brown, coffee, and other colors.

[0029] The natural plant hair dye of the present invention may be manufactured as a finished product, providing convenience for hair dyers to choose and purchase by designing different styles according to different occasions, or it may be designed as a semi-finished product, allowing purchasers to experience the fun of DIY. The core components of the natural plant hair dye of the present invention include legume extracts, reishi mushroom extracts, astragalus extracts, Polygonum multiflorum extracts, vegetable oils, and active ingredients extracted from natural plants such as erythritol, L-proline, ferulic acid, and 4-aminobutyric acid. These extracts, vegetable oils, and active ingredients are all derived from 23 different materials, including black rice, black beans, black sesame, rice, walnuts, senna, honey, edible oil, edible essence, black hulless barley, black buckwheat, black ginseng, erythritol (one or more types of erythritol, such as grape, melon, or mushroom, can be used), osmanthus flowers, wild lychee, sanshichi, tama, rokuden, astragalus, licorice, kashu, star anise, and chia seeds. Of these ingredients, fresh raw materials such as honey immediately after brewing and edible oil immediately after production are preferably used. Among these natural plant ingredients, some require the outer skin, such as walnuts, and some require the rhizome, such as kashu. The hair dye of the present invention contains small amounts of sebacic acid, propylene glycol, etc., all of which are food-grade, and a small amount of extract remains after extraction, which is exactly the necessary component. In addition to sebacic acid, this hair dye may also contain Biota orientalis extract as a preservative, which can extend the shelf life of the finished hair dye. In the present invention, propylene glycol plays the role of a humectant, solubilizer, and antifreeze in the hair dye to retain moisture.

[0030] The mass percentages of the aforementioned legume extract, reishi mushroom 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). Small amounts of sebacic acid and propylene glycol are added, and the total mass percentage of these components in the hair dye is 38% (wt), with the remainder being pure water.

[0031] In a preferred embodiment of the present invention, the active ingredients extracted from natural plants in the hair dye further include one or more active ingredients from among chamomile (chamomillarecutita) flower extract, azadirachtin, soapberry (sapindus mukorossi) fruit peel extract, licorice (glycyrrhizauralensis) root extract, broom leaf (biota orientalis) extract, carrot (panaxginseng) root extract, and cordyceps. By adding these extracts, the hair can be provided with better nutrients, the opening of the hair cuticle can be promoted, and hair dryness, split ends, and hair loss can be prevented. Figures 1 and 2 are LC-MS test detection diagrams (POS) and LC-MS test detection diagrams (NEG), respectively, of the components of a natural plant hair dye according to one embodiment of the present invention.

[0032] As shown in Figures 1 and 2, the detection results indicate that in the hair dye of the present invention, the active ingredient of the legume extract is soy isoflavone, the reishi mushroom extract is ganoderic acid B and ganoderiol A, the active ingredient of the astragalus extract is 7,2'-dihydroxy-3',4'-dimethoxyisoflavane-7-O-glucoside, and the Polygonum multiflorum extract is stilbene glycoside / 2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside. The active ingredients extracted from natural plants further include erythritol, L-proline, ferulic acid, and 4-aminobutyric acid. In a preferred embodiment, the active ingredients extracted from natural plants further include 5,6,7,3',4',5'-Hexamethoxyflavanone, azadirachtin, and 2'-hydroxy-2,4,4',5,6'-pentamethoxychalcone.

[0033] Figure 3 shows the detection results of a natural plant hair dye according to one embodiment of the present invention, based on the "Cosmetic Safety Technical Specifications." As shown in Figure 3, the indicators for the total number of colonies, the total number of molds and yeasts, heat-stable coliforms, Staphylococcus aureus, and Pseudomonas aeruginosa in the hair dye according to the present invention all meet the safety requirements of the relevant standards.

[0034] In a preferred embodiment of the present invention, the hair dye can be used in combination with a type B agent to shorten the dyeing time. Preferably, a hydrogen peroxide emulsion or salicylic acid is used as the type B agent. According to the research results of the team of the present invention, adding 18% (wt) of type B agent to the hair dye of the present invention can significantly shorten the dyeing time to within 15 minutes. The dyeing time will be shortened as the proportion of type B agent added increases, but this will deviate from the spirit of the present invention, as using too much type B agent may damage the hair. When the amount of type B agent added is reduced to 9% (wt), the dyeing effect is almost the same as when no type B agent is added. In other words, the factors that promote cuticle opening are dominated by natural plant-derived active ingredients, and the black dyeing time increases sharply to about 90 minutes. The type B agent used in the present invention does not have an unpleasant irritating odor such as ammonia odor, so when dyeing hair, the hair dye emits a refreshing scent derived from plants, providing a pleasant cooling sensation. Statistical analysis of 100 hair dyers (typically aged 40-50) who added 18% (wt) of type B agent showed that the dyeing time was in the range of 8-15 minutes, and no cases of skin allergy or scalp irritation were observed. Statistical analysis of 100 hair dyers (typically aged 60-90) who added 9% (wt) of type B agent showed that the dyeing time was approximately 90 minutes, and no cases of skin allergy or scalp irritation were observed. The hair dye of the present invention shows very favorable results for hair dyers even when an appropriate amount of type B agent is added. In a preferred embodiment of the present invention, since pure natural plant components such as mole oak extract, carrot root extract, and Polygonum multiflorum root extract are used as hair care components, the pH value of the synthesized hair dye is close to neutral, and the sensory irritation to people is mild, so there is no need to use a separate pH adjuster. In this invention, since compounding components such as legumes and vegetable oils are used, the resulting product has a refreshing plant-derived aroma and does not require adjustment with a conditioning agent.

[0035] In this invention, each component has good affinity with the human body and does not oxidize even after more than 4 hours in the air, ensuring sufficient time for the hair dyeing process. Therefore, there is no need to separately use various antioxidants and ascorbic acid components. In this invention, we take dyeing white or gray hair black as an example, but if you want to dye it a different color, you can obtain the desired color by adding plant pigments to the hair dye of this invention and, if necessary, adding a pH adjuster.

[0036] The hair dye of the present invention is not limited to being manufactured in liquid oil form, but may also be manufactured in a form suitable for stirring and mixing, such as paste, milky, creamy, or viscous form. Furthermore, some components may be manufactured in liquid oil form, and some may be pulverized into powder form. For example, osmanthus flowers, wild lychee, sanshichi, doma, rokujo, astragalus, licorice, kashu, star anise, chia seeds, etc., may be pulverized into powder form, mixed, bottled, and prepared for use. In one embodiment of the present invention, of the above 23 components, powdered edible essence is used for the edible essence, and all components except honey and edible oil are pulverized into powder form and prepared for use. [Examples]

[0037] Example 1 The natural plant hair dye contains legume extracts, reishi mushroom extracts, astragalus extracts, Polygonum multiflorum extracts, and vegetable oils, and further contains active ingredients extracted from natural plants such as erythritol, L-proline, ferulic acid, and 4-aminobutyric acid, with the mass percentages of the legume extracts, reishi mushroom extracts, astragalus extracts, Polygonum multiflorum extracts, vegetable oils, erythritol, L-proline, ferulic acid, and 4-aminobutyric acid being 10:5:5:10:50:5:5:5:5.

[0038] The method for producing the natural plant hair dye involves the steps of producing legume extract, reishi mushroom extract, astragalus extract, and Polygonum multiflorum extract, which include: crushing the dried raw materials, sieving them, dissolving the resulting powder in a 50% aqueous propylene glycol solution and extracting it with an ultrasonic extractor, vacuum suction filtration of the resulting extract, vacuum concentration to obtain the extract, and then uniformly mixing each extract in the above proportions to obtain an extract powder.
