Description

Technical Field

[0001] The present invention belongs to the technical field of skin care products, and particularly relates to an essential oil composition for preventing hair loss and promoting hair growth. Background Art

[0002] With the acceleration of the modern life rhythm and the improvement of health needs, hair loss has become a global health challenge. According to statistics, the number of people suffering from hair loss in China has exceeded 250 million. The market scale of anti-hair loss products continues to expand. The sales volume of anti-hair loss drugs reached 4.7 billion yuan in 2023 and is expected to exceed 5 billion yuan in 2024. At the same time, the hair medical service market is also growing rapidly, and the market scale is expected to reach 138.1 billion yuan by 2030, with a compound annual growth rate of more than 22%. However, traditional anti-hair loss methods such as hair transplantation or drug treatment are highly dependent, and consumers are urgently in need of safer and more convenient daily care solutions. Natural essential oil compositions have gradually become the research focus in the anti-hair loss field due to their mild ingredients and good permeability.

[0003] Among the current anti-hair loss and hair growth active ingredients, although minoxidil has been recognized globally, it is only limited to drug use in China, and there is a lack of corresponding equivalent substitutes in the cosmetics field. Most of the existing anti-hair loss cosmetics are based on aqueous systems, and the active ingredients have large molecular weights, resulting in low transdermal efficiency and difficulty in adapting to oily formulations. Although the oily system has advantages such as small molecular weight and strong permeability, the related technical research is insufficient, resulting in a blank in the market of oil-based anti-hair loss products and unable to meet the needs of consumers for high-efficiency and natural hair care products.

[0004] In view of the above problems, the present invention proposes an oily anti-hair loss and hair growth essential oil composition, which fills the technical gap of oil-based anti-hair loss products through the synergistic effect of specific plant essential oils and penetration enhancers. Summary of the Invention

[0005] The object of the present invention is to provide an essential oil composition for preventing hair loss and promoting hair growth. By mixing specific proportions of penetration-promoting, blood-circulation-promoting, antibacterial, and repair compositions, an anti-hair loss and hair growth essential oil is prepared. This composition improves scalp blood flow through blood-circulation-promoting components, optimizes the hair follicle environment through antibacterial components, activates hair follicles through repair components, and enhances the absorption of other components through penetration-promoting components, thereby effectively increasing hair density and promoting hair growth rate.

[0006] The technical solution adopted by the present invention is specifically as follows: An essential oil composition for preventing hair loss and promoting hair growth, comprising a penetration-promoting composition, a blood-circulation-promoting composition, an antibacterial composition, and a repair composition, wherein: The penetration-promoting composition comprises the following components: isononyl isononanoate, isododecane, menthol; The blood-circulation-promoting composition comprises the following components: ginger root oil, grapefruit peel oil; The antibacterial composition comprises the following components: Melaleuca alternifolia leaf oil, lavender oil; The repair composition comprises the following components: rosemary leaf oil, castor oil, sesame seed oil, neroli oil; Wherein, the ratio of the penetration enhancer composition, blood circulation promoter composition, antibacterial composition and repair composition by weight parts is (50-500):1:(15-18):(15-18).

[0007] In a preferred embodiment, the penetration enhancer composition comprises the following components by weight parts: 5-40 parts of isononyl isononanoate, 30-90 parts of isododecane, 1-5 parts of menthol.

[0011] In a preferred embodiment, the application of the anti-hair loss and hair growth essential oil composition described in the present application in the preparation of anti-hair loss and hair growth bathing products.

[0012] A preparation method of an anti-hair loss and hair growth essential oil composition, applicable to the anti-hair loss and hair growth essential oil composition described in any one of the above, characterized in that: it comprises the following steps: St1: Put the penetration enhancer composition into a production pot, stir and heat to 60-65 °C until the penetration enhancer composition is dissolved and transparent; St2: Sequentially put the blood circulation promoter composition, antibacterial composition and repair composition into the production pot, stir for 5-10 minutes, and naturally cool to room temperature to obtain the anti-hair loss and hair growth essential oil composition.

[0013] The technical effects achieved by the present invention are: The present invention mixes a penetration - promoting composition, a blood - circulation - promoting composition, an antibacterial composition, and a repair composition in specific proportions to obtain an anti - hair - loss and hair - growth essential oil composition. The blood - circulation - promoting composition promotes blood circulation in the scalp, the antibacterial composition improves the hair follicle environment, the repair composition repairs and activates the hair follicles, and the penetration - promoting composition can enhance the permeability of other components. As a result, the anti - hair - loss and hair - growth essential oil composition not only performs excellently in increasing hair density but also achieves excellent results in promoting hair growth rate. Detailed implementation mode

[0015] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0016] Secondly, the so - called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or selectively mutually exclusive embodiment with other embodiments.

[0017] Embodiment Embodiment 1 Sequentially add 17 g of isononyl isononanoate, 67.7 g of isododecane, and 2 g of menthol into the same container, and mix evenly to obtain a penetration - promoting composition; Sequentially add 0.2 g of ginger root oil and 0.2 g of grapefruit peel oil into the same container, and mix evenly to obtain a blood - circulation - promoting composition; Sequentially add 0.5 g of Melaleuca alternifolia leaf oil and 6 g of lavender oil into the same container, and mix evenly to obtain an antibacterial composition; Sequentially add 0.2 g of rosemary leaf oil, 5 g of castor oil, 1 g of sesame seed oil, and 0.2 g of neroli oil into the same container, and mix evenly to obtain a repair composition; Put the penetration - promoting composition into a production pot, stir and heat it to 65 °C until the penetration - promoting composition becomes dissolved and transparent. Then, put the blood - circulation - promoting composition, the antibacterial composition, and the repair composition into the production pot, stir for 10 minutes, and naturally cool to room temperature to obtain an anti - hair - loss and hair - growth essential oil composition. Among them, the proportions of the penetration - promoting composition, the blood - circulation - promoting composition, the antibacterial composition, and the repair composition by weight are 216.75:1:16.25:16.

[0018] It should be noted that in this embodiment, the same essential oil may have multiple effects, which can further enhance the effects of the essential oil composition. In order to better describe the effects of various essential oils, in this embodiment, only one effect of each essential oil is taken for description. Of course, this does not constitute a specific limitation.

[0019] When alleviating hair loss problems, the penetration - enhancing composition can enhance the permeability of other components. Among them, isononyl isononanoate, as a light solvent, reduces the viscosity of the essential oil, promotes the uniform dispersion of other active ingredients, and enhances permeability; isododecane, a volatile solvent, helps to quickly penetrate into the hair follicles, improving the bioavailability of other ingredients; menthol stimulates cold - sensitive receptors to produce a cool feeling, dilates the capillaries of the scalp, increases local blood flow, and promotes the nutritional supply of hair follicles. The blood - circulation - promoting composition can promote blood circulation in the scalp. Among them, ginger root oil contains gingerol (such as gingerol), which activates the TRPV1 receptor, stimulates the proliferation of dermal papilla cells, and accelerates the metabolic cycle of hair follicles; grapefruit peel oil is rich in various active ingredients, with certain irritant and warming effects. When used on the skin surface, it may cause local vasodilation by stimulating skin nerve endings, thereby promoting blood circulation. In the antibacterial composition, Melaleuca alternifolia leaf oil is rich in terpinen - 4 - ol, which inhibits pathogenic bacteria such as Malassezia, reducing scalp inflammation and hair follicle blockage; lavender oil contains linalool and linalyl acetate, which inhibits Staphylococcus aureus, relieves scalp sensitivity and inflammation, and reduces the causes of hair loss. In the repair composition, rosemary leaf oil contains carnosic acid and rosmarinic acid, which inhibit the activity of 5α - reductase, reduce the level of DHT (the main culprit of hair loss), and prolong the growth phase of hair follicles; castor oil contains 90% ricinoleic acid (ω - 9 fatty acid), forming a lipid protective film, locking in the moisture of hair follicles, repairing damaged hair cuticles, and reducing hair breakage; sesame seed oil is rich in sesamin and vitamin E, which antioxidant - protects the cell membrane of hair follicles, promotes keratin synthesis, and improves hair strength; neroli oil contains nerolidol and limonene, which regulate the sebum secretion of the scalp, balance the micro - ecosystem, and relieve hair follicle atrophy caused by excessive oiliness. Each component forms a multi - dimensional anti - hair - loss synergistic effect from penetration assistance, blood - circulation promotion, inflammation control to hair follicle repair and activation.

[0020] Example Two Add 8.5 g of isononyl isononanoate, 83.85 g of isododecane, and 1 g of menthol to the same container in sequence, and mix evenly to obtain the penetration - enhancing composition.

[0021] Example 3 Add 34 g of isononyl isononanoate, 35.4 g of isododecane, and 4 g of menthol into the same container in sequence, and mix evenly to obtain a penetration-enhancing composition; Add 0.4 g of ginger root oil and 0.4 g of grapefruit peel oil into the same container in sequence, and mix evenly to obtain a circulation-promoting composition; Add 1 g of Melaleuca alternifolia leaf oil and 12 g of lavender oil into the same container in sequence, and mix evenly to obtain an antibacterial composition; Add 0.4 g of rosemary leaf oil, 10 g of castor oil, 2 g of sesame seed oil, and 0.4 g of neroli oil into the same container in sequence, and mix evenly to obtain a repair composition; Put the penetration-enhancing composition into a production pot, stir and heat it to 65 °C until the penetration-enhancing composition becomes dissolved and transparent, then put the circulation-promoting composition, antibacterial composition, and repair composition into the production pot, stir for 10 minutes, and naturally cool to room temperature to obtain an anti-hair loss and hair growth essential oil composition, wherein the weight ratio of the penetration-enhancing composition, circulation-promoting composition, antibacterial composition, and repair composition is 91.75:1:16.25:16.

[0022] Test Example Test the volunteers with the essential oil compositions prepared in Examples 1 to 3, and evaluate their effectiveness.

[0023] Experimental grouping: 40 volunteers were arranged in the experimental group, with 10 people in a group, half male and half female. Among them, one group was used as the control group, and the remaining groups were experimental groups. The control group used a commercially available water-based anti-hair loss shampoo, and each experimental group randomly tested one of the anti-hair loss and hair growth essential oil compositions in Examples 1 to 3.

[0024] Screening criteria: 1. Aged 25 - 50 years old, hair loss grade II - IV; 2. The tested volunteers had hair loss grade II - IV; 3. Apply it to the scalp every night, massage for 3 to 5 minutes, and then rinse with water for 8 weeks.

[0025] Usage: The test volunteers take an appropriate amount of the sample every day, apply it to the scalp, massage for 3 to 5 minutes, and then rinse with water for 8 weeks. Do not use other products during the trial period.

[0026] Data collection: At Wk1 and Wk1 respectively, collect the hair density (number of hairs per unit area) and hair growth rate (length from the hair root to the hair tip) of the test volunteers.

[0027] Test results: 1. The test volunteers who continuously used the anti - hair - loss and hair - growth essential oil composition for 8 weeks had significantly higher hair density than the control group, indicating that the sleep essential oils prepared in Examples 1 to 3 can effectively increase the hair density (number of hairs per unit area) of the test volunteers. For the hair density results, please refer to Table 1.

[0028]

[0029] It can be seen from the data in the table that as the usage time increases, the hair density of the test volunteers in Experimental Groups 1 to 3 shows an upward trend, and the upward trend is significantly faster than that of the control group.

[0030] 2. During the test process, the hair growth rate of the test volunteers was also evaluated. By regularly measuring the length from the hair root to the hair tip, the changes in hair growth were recorded and analyzed. For the results, please refer to Table 2.

[0031]

[0032] The experimental results show that the test volunteers who used the anti - hair - loss and hair - growth essential oil composition also had a significantly higher hair growth rate than the control group. This finding further confirms the effectiveness of the essential oil composition of the present invention in promoting hair growth.

[0033] Specifically, after 8 weeks of using the essential oil composition of the present invention, the hair growth rates of the test volunteers in Experimental Groups 1 to 3 were significantly improved. In contrast, the change in the hair growth rate of the control group was minimal and almost remained at the initial level. This distinct contrast result clearly demonstrates the remarkable effect of the essential oil composition of the present invention in promoting hair growth. The anti-hair loss and hair growth promoting essential oil compositions prepared through Examples 1 to 3 have achieved remarkable results in increasing hair density and promoting hair growth rate. These experimental results fully prove the effectiveness and practicality of the present invention. At the same time, the anti-hair loss and hair growth promoting essential oil compositions prepared in the examples not only possess the advantages of small molecular weight, strong penetrability, and high activity of oily cosmetics, but also overcome the limitation that minoxidil cannot be used in cosmetics and solve the deficiencies of oily anti-hair loss and hair growth promoting cosmetics in the field of cosmetics technology.

[0034] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention, unless otherwise specified and limited, are implemented according to the conventional means in the art.
