[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The color-locking hair care essential oil prepared by the present invention is made from natural ingredients such as special environmental biological extracts and biological fermentation products, and is prepared using a green and sustainable process. This allows the product to have multiple functions such as color locking, maintenance, antibacterial and anti-inflammatory effects. The production process reduces environmental pollution, conforming to the concepts of green chemistry and sustainable development. Functionally, it can meet consumers' needs for multi-faceted hair care while ensuring the mildness and safety of the product, providing the market with a higher-quality, environmentally friendly, and fully functional hair care product.

[0012] 2. The active substances extracted from deep-sea algae and polar plants in this invention are optimized through bio-fermentation technology and can act precisely on the hair scales and cortex. Compared with traditional hair care essential oils, this technology enables the added bioactive peptides and polysaccharides to form a more stable hair color-stabilizing network inside the hair, which can effectively reduce pigment loss, while enhancing the hair's antioxidant and UV resistance, providing more lasting protection for the hair and allowing the dyed hair color to last longer.

[0013] 3. The present invention introduces poly (N-isopropylacrylamide) (PNIPAM) to construct an intelligent temperature-responsive color-locking system. When hair care oil contacts the hair, a color-locking film is formed on the hair surface as the temperature changes. Compared with ordinary hair care products, this design can dynamically adjust the pore size according to the ambient temperature. While effectively preventing external damage to hair color, it ensures normal breathing and nutrient absorption of the hair. On the basis of achieving the color-locking function, it improves the hair care effect and provides a more suitable hair care environment.

This invention utilizes nano-scale microcapsule technology to encapsulate easily oxidized or unstable color-locking ingredients, using natural polysaccharides or protein-based wall materials. Unlike the traditional method of directly adding ingredients, this technology allows the color-locking ingredients to be slowly released on the hair surface, extending the duration of action of the active ingredients, reducing the loss of ingredients due to light and oxidation, and reducing irritation to the scalp, achieving long-lasting color lock and more gentle hair care.

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. It should be understood by those skilled in the art that the embodiments are merely to help understand the present invention and should not be regarded as specific limitations of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative work are within the scope of protection of the present invention. The process parameters for which specific conditions are not specified in the following examples are generally based on conventional conditions.

[0017] The endpoints of the ranges and any values disclosed herein are not limited to the precise ranges or values, and these ranges or values should be understood to include values close to these ranges or values. For numerical ranges, the endpoints of each range, the endpoints of each range and individual point values, and the individual point values can be combined with each other to form one or more new numerical ranges, and these numerical ranges should be considered to be specifically disclosed in the present invention.

[0018] like Figure 1 As shown, the present invention provides a method for preparing color-locking hair care essential oil, which mainly comprises the following steps: S1. Screening raw materials with potential color-locking function. Deep-sea algae extracts and polar plant extracts are washed and dried, and then crushed into a particle size of 50-100 mesh using a grinder. The biofermentation products are collected and centrifuged to remove impurities, and then spray-dried to form a powder. S2. Optimize the structure of active substances using biofermentation and genetic engineering technologies; Specifically, such as Figure 2 As shown, the biological fermentation technology in S2 uses genetically engineered lactic acid bacteria and yeast as fermentation strains, and ferments at a fermentation temperature of 25°C to 35°C for 48 to 72 hours.

[0019] Furthermore, during the fermentation process, high-performance liquid chromatography (HPLC) is used to monitor the concentration changes of bioactive peptides and polysaccharides in the fermentation broth in real time. When the concentration reaches the peak, the fermentation is terminated. The structure of the active substances is optimized through microbial fermentation, thereby improving their efficiency of absorption by hair and color-locking effect.

[0020] S3, using microencapsulation technology to encapsulate the color-locking ingredients; Specifically, such as Figure 3 As shown, in the microcapsule preparation process of S3, the microcapsules are prepared through an emulsification-curing process. First, the color-locking component and the wall material raw material are dissolved in a suitable solvent, emulsified under a stirring speed of 800-1200 rpm, and then a curing agent is added to carry out a curing reaction. The curing agent is glutaraldehyde, and the curing reaction is carried out for 1-3 hours depending on the production environment temperature.

[0021] Furthermore, the particle size of the prepared microcapsules ranges from 50 to 200, and the encapsulation rate ranges from 80% to 90%, which protects easily oxidized or unstable color-locking ingredients, achieves their slow release on the hair surface, and prolongs the action time.

[0022] S4. Mix poly (N-isopropylacrylamide) (PNIPAM) and a color-locking component in a predetermined ratio, add the mixture to an ethanol-water solution with a volume fraction of 20%, and stir and dissolve at 40-50°C and a stirring speed of 600-800 rpm to form a uniform intelligent temperature-responsive color-locking system solution. Poly (N-isopropylacrylamide) (PNIPAM) undergoes phase changes at different temperatures. When the hair care oil contacts the hair, as the temperature rises (human body temperature or ambient temperature changes), a dense color-locking film is formed on the hair surface. The film can dynamically adjust the pore size according to the ambient temperature, achieving the dual functions of intelligent color locking and maintenance. S5. Add silk protein, hydrolyzed collagen, rosemary essential oil, and tea tree essential oil to the above solution in sequence, wherein the silk protein and hydrolyzed collagen must first be dissolved in deionized water to prepare a solution with a mass concentration of 10% to 15% and then added. During the addition process, the stirring speed is maintained at 400 to 600 rpm for 10 to 15 minutes to form a multimodal functional component mixed system, thereby organically integrating the color-locking function with the functions of repairing damaged hair, antibacterial and anti-inflammatory, and improving the overall performance of the product; S6. Use supercritical fluid extraction technology to extract plant color-locking ingredients; Specifically, such as Figure 4 As shown, S6 supercritical fluid extraction uses supercritical carbon dioxide fluid, with an extraction pressure of 15-30 MPa, an extraction temperature of 30°C-50°C, and an extraction time of 1-3 hours. Supercritical carbon dioxide fluid extraction technology replaces traditional organic solvent extraction, reducing environmental pollution while more efficiently extracting color-locking components in plants, thereby improving product purity and quality.

[0023] S7, mixing the above ingredients with base oil; Specifically, such as Figure 5 As shown, in the mixing and preparing process in S7, each component is mixed with the base oil by high-speed stirring at a stirring speed of 1000 to 2000 rpm for 15 to 30 minutes to promote the initial dispersion of each component; Furthermore, during the stirring process, premix at a low speed of 1000-1200 rpm for 5-10 minutes to initially disperse the ingredients, then increase the stirring speed to 1500-2000 rpm and continue stirring for 10-20 minutes to ensure that the ingredients are evenly mixed to form a stable hair care essential oil system.

[0024] S8. Use continuous and automated production lines for filling and packaging; Further, such as Figure 6 As shown, the continuous and automated production line in S8 needs to preheat the equipment before filling and packaging. The preheating temperature is 60℃~80℃ and the preheating time is 10~15 minutes. During the filling and packaging process in S8, nitrogen is filled into the production line cavity through the inert gas protection device, and the nitrogen filling flow rate is 5 to 10 L / min.

[0025] Specifically, during the filling and packaging process of the continuous and automated production line in S8, the filling and transportation speed is 50 to 100 bottles per minute; Furthermore, the packaging process adopts hot pressing sealing technology, with the hot pressing temperature set to 120℃~150℃, the pressure 0.3~0.5MPa, and the packaging time 2~3 seconds. The continuous and automated production line is used to improve production efficiency. At the same time, inert gas protection reduces product oxidation during the packaging process and ensures product quality.

[0026] It should be pointed out in particular that the above parameter ranges are all elastic ranges, and are parameter data that have been verified in actual production and can achieve stable reactions during the preparation process. Within these parameter ranges, the preparation of target products and related intermediate substances can be effectively achieved. In actual applications, it is only necessary to ensure that the values of the relevant parameters are within the range accuracy specified in this application to ensure the smooth progress of the process and the stable production of the product.

[0027] Furthermore, based on the preparation method of the above-mentioned color-locking hair care essential oil, the present invention also discloses a color-locking hair care essential oil prepared by the above-mentioned method. The application document is further disclosed below in combination with the specific preparation method data. The specific preparation process thereof can be equivalent to: S1. Screening raw materials: deep-sea algae extract and polar plant extract are selected, washed and dried, and then crushed to a particle size of 75 mesh using a grinder; the biofermentation product is collected, centrifuged to remove impurities, and then spray-dried to form a powder; S2. Optimize the structure of active substances using biofermentation and genetic engineering technologies: Genetically engineered lactic acid bacteria and yeast were used as fermentation strains. Fermentation was performed at 30°C for 60 hours. The concentrations of bioactive peptides and polysaccharides in the fermentation broth were monitored in real time, and fermentation was terminated when the concentrations reached their peak. S3. Encapsulate the color-locking component using microencapsulation technology: Prepare microcapsules through an emulsification-curing process. First, dissolve the color-locking component and the wall material in a suitable solvent, emulsify them at a stirring speed of 1000 rpm, and then add a curing agent to carry out a curing reaction. The prepared microcapsules have a particle size of 125 and an encapsulation efficiency of 85%; S4. Mix poly (N-isopropylacrylamide) (PNIPAM) and the color-locking component in a predetermined ratio, add the mixture to an ethanol-water solution having a volume fraction of 20%, and stir the mixture at 45°C and 700 rpm to form a uniform intelligent temperature-responsive color-locking system solution. S5. Add silk protein, hydrolyzed collagen, rosemary essential oil, and tea tree essential oil to the above solution in sequence: first dissolve silk protein and hydrolyzed collagen in deionized water to prepare a solution with a mass concentration of 12.5%, and then add them. During the addition process, maintain the stirring speed at 500 rpm for 12.5 minutes to form a multimodal functional component mixing system; S6. Use supercritical carbon dioxide fluid to extract the plant color-locking components: extraction pressure 22.5 MPa, extraction temperature 40°C, extraction time 2 hours; S7. Mix the above ingredients with the base oil: pre-mix at a low speed of 1100 rpm for 7.5 minutes to disperse the ingredients, then increase the stirring speed to 1750 rpm and continue stirring for 15 minutes; S8. Use a continuous, automated production line for filling and packaging: the filling and transportation speed is 75 bottles / minute, and the packaging process adopts hot pressing and sealing technology. The hot pressing temperature is set to 135°C, the pressure is 0.4MPa, and the packaging time is 2.5 seconds. Before filling and packaging, the equipment is preheated to 70°C and the preheating time is 12.5 minutes. During the filling and packaging process, nitrogen is filled into the production line cavity at a nitrogen filling flow rate of 7.5L / min.

[0028] Based on the above steps, the color-locking hair care essential oils were prepared using different ratios used in Examples 1 to 5, wherein the deep-sea algae extract was removed in Comparative Example 1, the polar plant extract, the biological fermentation product, the microcapsule wall material, and the color-locking component were removed in Comparative Example 2, the silk protein and the hydrolyzed collagen were removed in Comparative Example 3, and a comparative example 4 was added, which used conventional hair care essential oils in the prior art as a control group, and the specific values were: Table 1: Composition value table of hair care essential oils (weight ratio) The color-locking hair care essential oil prepared based on the above method and ratio needs to ensure the color-locking effect, hair repair effect, antioxidant capacity and other properties. The hair care essential oils prepared in Examples 1 to 5 and Comparative Examples 1 to 3 were tested under the same data conditions by the following method: Color lock effect test: Select multiple strands of hair of the same length and dyed the same color (e.g., brown), use equal amounts of the hair care essential oils of each embodiment and comparative example, and test under the same lighting and washing conditions; Specifically, the light intensity was 5000 lux, and the light was applied for 8 hours per day; each control group used the hair care essential oil of the corresponding embodiment and comparative example, and the shampoo used was the same brand, and the water temperature was 40° C., and the hair was washed 3 times a week, each washing for 5 minutes; Use a colorimeter to measure hair color changes every week and record the color difference ΔE value. The smaller the ΔE value, the better the color locking effect.

[0029] Hair repair effect test: prepare multiple strands of hair treated with perm solution, evenly apply the hair care essential oils of each embodiment and comparative example on the hair, and perform care three times a week for four consecutive weeks; After a period of care, use a hair smoothness tester to measure the friction coefficient of the hair. The lower the friction coefficient, the smoother the hair and the better the repair effect. At the same time, observe the state of the hair scales on the surface of the hair under a microscope. Complete and tightly arranged hair scales indicate a good repair effect.

[0030] Antioxidant capacity test: DPPH free radical scavenging experiment was used for testing. 0.5 g of each hair care essential oil sample was added to a test tube containing a DPPH free radical solution with a concentration of 0.1 mmol / L. After reacting in a dark environment for 30 minutes, the absorbance value was measured at a wavelength of 517 nm using a spectrophotometer.

[0031] The DPPH free radical scavenging rate was calculated according to the formula: DPPH free radical scavenging rate (%) = [1 ~ (A sample ~ A blank) / A control] × 100%, where A sample is the absorbance value after adding the hair care essential oil sample, A blank is the absorbance value of the reaction system without adding the hair care essential oil sample, and A control is the absorbance value of the solution without adding the sample but containing DPPH free radicals. The higher the free radical scavenging rate, the stronger the antioxidant ability of the hair care essential oil.

[0032] Nourishing and moisturizing effect test: Prepare multiple hair samples of the same length and quality that have been degreased (to simulate dry and damaged hair). Apply equal amounts of the hair care essential oils of each example and comparative example evenly to the corresponding hair samples. Use the oils three times a week for four consecutive weeks. After the care cycle, use a professional hair moisture tester to test the moisture content of each strand of hair. The hair moisture tester measures the moisture content by sensing the change in conductivity between the moisture in the hair and a specific sensor, and directly displays the percentage value. The higher the value, the stronger the ability of the hair care oil to replenish moisture and retain moisture for the hair, that is, the better the nourishing and moisturizing effect.

[0033] Based on the above test items, the samples of Examples 1 to 5 and Comparative Examples 1 to 4 were tested for actual use effects, and the specific test results are shown in the following table: Table 2: Performance comparison analysis table Based on the above data sample experimental data, see Figure 7 , the performance of Examples 1 to 5 and Comparative Examples 1 to 4 are analyzed item by item: From Examples 1 to 5, as the dosage of key color-locking ingredients such as deep-sea algae extract, polar plant extract, and bio-fermentation product gradually decreases, the color-locking effect shows a trend of gradually weakening, as manifested by a gradual increase in the ΔE value. This indicates that these special ingredients play a vital role in maintaining the stability of hair color, and the reduction in their content will directly affect the formation and stability of the hair color-stabilizing network.

[0034] Comparative Example 1 excluded the deep-sea algae extract. Compared with Examples 1 to 5, the color-locking effect was significantly reduced and the ΔE value was significantly increased. This indicates that the lack of the deep-sea algae extract ingredient significantly reduced the ability of hair to resist pigment loss caused by external factors. Comparative Example 2 excluded the polar plant extract, and Comparative Example 3 excluded the biological fermentation product, and the color-locking effect also deteriorated.

[0035] Furthermore, in Examples 1 to 5, as the content of ingredients such as silk protein and hydrolyzed collagen, which play an important role in hair repair, gradually decreases, the hair repair effect gradually weakens, which is manifested as a gradual increase in the friction coefficient. These ingredients are effective in filling damaged hair areas, improving the surface condition of hair, and reducing the friction coefficient. Reducing their use will affect the smoothness and repair effect of the hair.

[0036] Comparative Examples 1 to 3 respectively eliminated deep-sea algae extract, polar plant extract, and biological fermentation product. Although silk protein and hydrolyzed collagen were retained, the hair repair effect was still lower than that of Examples 1 to 5 due to the lack of other synergistic special ingredients, and the friction coefficient was significantly higher. These ingredients and repair ingredients need to cooperate with each other in the specific process to promote hair repair. The lack of any one of them will weaken the overall repair effect.

[0037] Furthermore, in Examples 1 to 5, as the proportion of antioxidant ingredients such as polar plant extracts and biological fermentation products gradually decreases, the DPPH free radical scavenging rate gradually decreases and the antioxidant capacity gradually weakens. Antioxidant ingredients such as polar plant extracts and biological fermentation products are key factors in improving the antioxidant capacity of the product, and changes in their content directly affect the free radical scavenging effect.

[0038] Comparative Example 2 eliminated the polar plant extract, and Comparative Example 3 eliminated the biological fermentation product, resulting in an antioxidant capacity significantly lower than that of Examples 1 to 5, and a significantly reduced free radical scavenging rate. After the loss of these ingredients, the product's ability to resist oxidative damage was significantly reduced.

[0039] Finally, with regard to the nourishing and moisturizing effect, in Examples 1 to 5, as the amount of deep-sea algae extracts, polar plant extracts, and bio-fermentation products that may contain moisturizing-related ingredients gradually decreases, the moisture content of the hair gradually decreases, and the nourishing and moisturizing effect gradually weakens.

[0040] After the corresponding special ingredients in Comparative Examples 1 to 3 were removed, the moisture content of the hair was significantly lower than that in Examples 1 to 5, and the nourishing and moisturizing effect was poor. The lack of the corresponding ingredients would seriously affect the moisturizing performance of the product.

[0041] Relatively speaking, compared with the corresponding color locking, repairing, anti-oxidation and nourishing and moisturizing effects of Comparative Example 4, the finished product data of any one of Examples 1 to 5 in the present invention are significantly improved.

[0042] Comparative Example 4 uses a conventional formula in the prior art. Its color-locking effect is far inferior to that of Examples 1 to 5, with the largest ΔE value, the worst performance in hair repair, and the highest friction coefficient. Furthermore, it has the weakest antioxidant capacity, the lowest free radical scavenging rate, relatively poor nourishing and moisturizing effects, and the lowest hair moisture content. For the above data, comparative examples one to three lack corresponding ingredients, resulting in no significant improvement in their color-locking, repairing, anti-oxidation, and nourishing and moisturizing effects compared to traditional products, namely comparative example four. Their deep-sea algae extracts, silk protein, hydrolyzed collagen, polar plant extracts, biological fermentation products and other materials have significantly improved their color-locking, repairing, anti-oxidation, and nourishing and moisturizing effects.

[0043] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention.
