Abstract

The present invention provides a method for preparing prickle fruit oil, a product thereof, and application thereof in hair products. The preparation method comprises the following steps: drying prickle fruit seeds and then pressing them at room temperature to obtain crude oil; mixing the crude oil with acidic clay and diatomaceous earth, heating the oil, cooling the oil, and filtering the oil. The method first uses a cold pressing process to prepare the prickle fruit crude oil, and then uses a mixture of acidic clay and diatomaceous earth to decolorize, dehydrate, and remove odor. The refined prickle fruit oil obtained overcomes the drawbacks of the prickle fruit oil prepared in the prior art, such as strong odor, dark color, and high impurities, thereby increasing its compatibility in daily chemical products.

Description

Technical Field

[0001] The invention belongs to the technical field of oil processing, and relates to a preparation method of prickle fruit oil, a product thereof, and an application of the oil in hair products, and in particular to a preparation method of prickle fruit oil, a product thereof, and an application of the oil in hair products with the functions of protecting color, resisting high-temperature damage, or softening and repairing hair. Background Art

[0002] Prinsepia utilis Royle, also known as Prinsepia utilis Royle in Chinese, belongs to the genus Prinsepia in the Rosaceae family, subfamily Prunaceae. Also known as green thorn tip and oil-beating fruit, it grows on hillsides, wastelands, farmlands, roadsides, and in shady thickets at altitudes of 1,800-3,000 meters, remaining remarkably resilient even in the cold of winter.

[0003] The fruit of the Chinese prickly ash tree has a wide range of uses and a long history of medicinal use. Its kernels and leaves contain numerous essential macro- and trace elements, and are high in crude fat. They have the potential to clear heat and detoxify, reduce inflammation, promote blood circulation, relieve pain, aid digestion, and strengthen the stomach. The fruit oil (also known as qingna oil) has been used for many years as a popular edible oil. It is a highly recommended, environmentally friendly food. Regular consumption can lower blood lipids, regulate blood pressure, promote microcirculation, and enhance the body's immune system. Furthermore, because it is rich in unsaturated fatty acids and has a composition similar to human sebum, it also has the potential to regenerate and repair the skin, slow aging, and maintain moisture.

[0004] CN110724591A discloses a method for processing prickle fruit oil. This invention utilizes hot pressing to extract the oil, adding water to the oil dregs and extracting them with a subcritical fluid. The oil is then combined and refined, yielding a yield of 20-28%. The prickle fruit obtained by hot pressing has a strong and fragrant aroma and a dark color, and the final refining process is not dehydrated. Because the color and odor affect the appearance and odor of the finished skin care product formula, and because the refining process does not involve dehydration, its application in the daily chemical industry is limited due to its easy impact on the odor of the finished product formula.

[0005] CN112175713A discloses a process for preparing prickle fruit oil with a prolonged oxidation induction time. This process utilizes supercritical CO2 extraction. While enriching fatty acids, it also extracts volatile terpenes, anthraquinones, and small-scale pigments contained in the prickle fruit. The resulting crude oil has a pungent flavor and is high in impurities, significantly increasing the difficulty of subsequent purification. Furthermore, the process uses alkaline clay for purification, which reacts with components in the oil to saponify, increasing the saponification value and affecting the quality and stability of the prickle fruit oil. Summary of the Invention

[0006] In view of the deficiencies in the prior art, the present invention aims to provide a method for preparing prickle fruit oil, a product thereof, and applications thereof in hair products, and in particular to provide a method for preparing prickle fruit oil, a product thereof, and applications thereof in hair products having color protection, resistance to high temperature damage, or softening and repairing effects.

[0007] In order to achieve the purpose of the invention, the present invention adopts the following technical solutions:

[0008] In a first aspect, the present invention provides a method for preparing utilitarian fruit oil, the preparation method comprising the following steps:

[0009] (1) drying the seeds of the utilitarian fruit and pressing them at a temperature of 10-40° C. to obtain crude oil;

[0010] (2) The crude oil obtained in step (1) is mixed with acidic white clay and diatomaceous earth, subjected to heat treatment, then cooled, and filtered to obtain the prickle oil.

[0011] The invention creatively adopts a cold pressing process to prepare crude prickle fruit oil, and then uses a mixture of acidic white clay and diatomaceous earth to perform decolorization, dehydration and deodorization treatment, so that the obtained refined prickle fruit oil overcomes the disadvantages of the prickle fruit oil prepared in the prior art, such as strong odor, dark color and many impurities, and improves its adaptability in daily chemical products. At the same time, the preparation method has a simple process, can realize industrial production, and has the advantages of being non-toxic, highly effective, safe and free of introduction of exogenous solvents, so that the refined prickle fruit oil is more widely used in the field of daily chemical products.

[0012] In addition, in the prior art, prickle fruit oil is primarily used for health care, skin care, and beauty. The oleic acid and linoleic acid contained in it have been shown to have anti-cancer activity. However, currently, prickle fruit oil is rarely used in hair products. The prickle fruit oil prepared using the preparation method of the present invention has excellent color protection, resistance to high temperature damage, and softening and repairing effects on hair. Therefore, it can be used as a raw material to prepare hair products with the above-mentioned effects, expanding the application field of prickle fruit oil.

[0013] Preferably, the moisture content of the dried utilitarian fruit seeds is 2-6%, for example, 2%, 3%, 4%, 5%, 6%, etc. Other specific values within this numerical range can be selected and will not be described in detail here.

[0014] The prickle fruit seed raw material used in the preparation method of the present invention preferably has a moisture content of 2-6% because if the moisture content is higher than 6%, the moisture content in the prickle fruit oil will be too high, accelerating the acidification of the prickle fruit oil; if the moisture content is lower than 2%, the structural water of the prickle fruit seeds will be destroyed, and the unsaturated fatty acids therein will accelerate oxidation and affect the quality of the prickle fruit oil, all of which will have a negative impact on the color protection, resistance to high temperature damage and softening and repairing effects of the prepared prickle fruit oil.

[0015] Preferably, the usage amount of the acidic clay and diatomaceous earth is 1-6% of the mass of the crude oil, for example 1%, 2%, 3%, 4%, 5%, 6%, etc. Other specific values within this numerical range can be selected and will not be described here one by one.

[0016] The amount of acidic white clay and diatomaceous earth used in the preparation method of the present invention is preferably 1-6% of the mass of the crude oil because if the amount used is further increased, the effects of the obtained prickle fruit oil in terms of smell, color, and hair efficacy will not be significantly improved, and if the amount used is further reduced, the effects of the obtained prickle fruit oil in terms of smell, color, and hair efficacy will be significantly reduced.

[0017] Preferably, the mass ratio of the acidic clay to diatomaceous earth is (2-4):1, such as 2:1, 2.5:1, 3:1, 3.5:1, 4:1, etc. Other specific values within this numerical range can be selected and will not be described here one by one.

[0018] The present invention specifically uses a mixture of acidic clay and diatomaceous earth to refine crude prickle oil. This, on the one hand, prevents saponification reaction between the alkaline clay and components in the oil, which would affect the quality and stability of the prickle oil. On the other hand, the combined advantages of the acidic clay and diatomaceous earth are utilized. The combined use of the acidic clay and diatomaceous earth has a significant synergistic effect in reducing the odor and color of the prickle oil and improving the hair efficacy of the prickle oil. This combined advantage is even more pronounced when the mass ratio of the acidic clay and diatomaceous earth is selected to be (2-4):1.

[0019] Preferably, the heat treatment is performed at 50-70° C. (e.g., 50° C., 53° C., 55° C., 58° C., 60° C., 63° C., 65° C., 68° C., 70° C., etc.) for 0.5-1.5 h (e.g., 0.5 h, 0.7 h, 0.8 h, 1.0 h, 1.2 h, 1.3 h, 1.4 h, 1.5 h, etc.). Other specific values within the above numerical range can be selected and will not be repeated here.

[0020] The above-mentioned heating treatment is preferably performed at 50-70° C. because if the temperature is further increased, unpleasant odor will be produced, and if the temperature is further decreased, the decolorization effect will be less obvious.

[0021] Preferably, the cooling refers to cooling to below 35°C, such as 35°C, 30°C, 28°C, 25°C, 20°C, 15°C, etc.

[0022] Preferably, the filtration is performed at 0.1-0.5 MPa (eg, 0.1 MPa, 0.2 MPa, 0.3 MPa, 0.4 MPa, 0.5 MPa, etc.) using a 0.2-1.0 μm membrane.

[0023] Other specific point values within the above numerical range can be selected and will not be described in detail here.

[0024] In a second aspect, the present invention provides prickle fruit oil prepared according to the preparation method of prickle fruit oil described in the first aspect.

[0025] The prickle fruit oil product prepared by the preparation method of the present invention has a light fragrance or is substantially odorless, a low Gardner chroma value, few impurities, and no precipitation; the composition ratio of polyunsaturated fatty acids, monounsaturated fatty acids, and saturated fatty acids is close to the structure of human fatty acids, which is conducive to skin absorption; and it is creatively found that the prickle fruit oil product has excellent effects of protecting hair color, resisting high-temperature damage, and softening and repairing hair.

[0026] In a third aspect, the present invention further provides use of the utilitarian fruit oil according to the second aspect in preparing hair products.

[0027] Preferably, the hair product is a hair product with color protection effect.

[0028] Preferably, the hair product is used in a hair product having the effect of resisting high temperature damage.

[0029] Preferably, the hair product is used in a hair product with softening and repairing effects.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] The invention creatively adopts a cold pressing process to prepare crude prickle fruit oil, and then uses a mixture of acidic white clay and diatomaceous earth to perform decolorization, dehydration and deodorization treatment, so that the obtained refined prickle fruit oil overcomes the disadvantages of the prickle fruit oil prepared in the prior art, such as strong odor, dark color and many impurities, and improves its adaptability in daily chemical products. At the same time, the preparation method has a simple process, can realize industrial production, and has the advantages of being non-toxic, highly effective, safe and free of introduction of exogenous solvents, so that the refined prickle fruit oil is more widely used in the field of daily chemical products.

[0032] The prickle fruit oil product prepared by the preparation method of the present invention has a light fragrance or is substantially odorless, a low Gardner chroma value, few impurities, and no precipitation; the composition ratio of polyunsaturated fatty acids, monounsaturated fatty acids, and saturated fatty acids is close to the structure of human fatty acids, which is conducive to skin absorption; and it is creatively found that the prickle fruit oil product has excellent effects of protecting hair color, resisting high-temperature damage, and softening and repairing hair.

[0083]

[0084] From the test results in Tables 1-3, it can be seen that the mass ratios of saturated fatty acids, monounsaturated fatty acids and saturated fatty acids in the prepared Prinus utilis oil are all close to the 1:1:1 structure of human fatty acids.

[0091] Color protection efficacy test:

[0092] 1. Test purpose: To test the color difference of dyed hair using a colorimeter and evaluate the effect of clavatica arborvitae oil on hair color protection.

[0093] 2. Test samples:

[0094] Control group: shampoo blank matrix (10% sodium lauryl ether sulfate aqueous solution)

[0095] Sample group: Shampoo containing 1% of the purpureus fruit oil prepared in Examples 1-6 and Comparative Examples 1-6 (99 g of shampoo blank matrix was weighed, and 1 g of purpureus fruit oil was added, stirred evenly, and set aside)

[0100] 5. Test environment:

[0101] Constant temperature and humidity environment, temperature 21±1℃, humidity 50±10%

[0102] 6. Testing process:

[0103] (1) 39 dyed hair bundles were randomly divided into 13 groups, with 3 bundles in each group. Before the test, the chromaticity value of the hair bundles was measured using a colorimeter tester, and each hair bundle was measured 10 times (before treatment);

[0104] (2) After the measurement is completed, the hair bundles of the sample group are treated with purpureus purpureus oil shampoo at a dosage of about 0.2 g of sample per gram of hair bundle, evenly applied on the hair surface for 1 minute, and then rinsed clean; the hair bundles of the control group are treated with shampoo matrix and the treatment method is the same as the sample group;

[0105] (3) Wash the hair bundles 8 times according to step (2). After washing, place the hair bundles in a constant temperature and humidity environment (temperature 26±2°C; relative humidity 60±10%RH) to dry naturally.

[0106] (4) Use a colorimeter to measure the chromaticity value of the hair bundle, and measure each hair bundle 10 times (after treatment).

[0107] 7. Result analysis:

[0108] L, a, and b are the chromaticity values representing an object's color, or the color space coordinates of that color. L represents lightness and darkness (black and white), a represents red and green, and b represents yellow and blue. A colorimeter automatically compares the color difference between a sample and the object being inspected, outputting three sets of data: L, a, and b, along with the colorimetric delta E (ΔE). Smaller ΔE values indicate better color preservation. The results are shown in Table 5.

[0122] 5. Testing process:

[0123] (1) Hair scanning differential thermal analysis (DSC) test process:

[0124] (1.1) Thirty-nine hair bundles were randomly divided into 13 groups, each containing 3 bundles. The following treatments were performed:

[0125] Control group: Mildly damaged hair was washed with basic shampoo and then the surface moisture was wiped dry;

[0126] Sample group: After washing slightly damaged hair with basic shampoo, wipe off the surface moisture. When the hair is half dry, apply the purpureus utilis oil samples prepared in Examples 1-6 and Comparative Examples 1-6 (0.2 g sample per gram of hair) respectively, and massage along the direction of the hair scales for 3 minutes. Do not wash;

[0127] The control group and the sample group were blown with a hair dryer (high temperature, high wind speed, 10 cm away from the hair bundle) for 3 minutes respectively.

[0128] (1.2) Cut the processed hair into pieces of about 1.0 mm.

[0129] (1.3) Use a differential scanning calorimeter (DSC) to measure the DSC curve of the hair and calculate the absorption peak temperature (Td) and average absorption peak area (ΔHd) in the temperature range of 230°C-250°C.

[0130] (2) Hair scale scanning electron microscope testing process:

[0131] (2.1) Take two hair bundles, one for the control group and one for the sample group of Example 1, and perform the following treatments:

[0132] Control group: Mildly damaged hair was washed with basic shampoo and then the surface moisture was wiped dry;

[0133] Sample group: After washing slightly damaged hair with basic shampoo, wipe off the surface moisture. When the hair is half dry, apply the utilitarian fruit oil sample prepared in Example 1 (0.2g sample per gram of hair) and massage along the direction of the hair scales for 3 minutes. Do not wash.

[0134] The control group and the sample group were blown with a hair dryer (high temperature, high wind speed, 10 cm away from the hair bundle) for 3 minutes respectively.

[0135] (2.2) Randomly select 2 hairs from each of the control group and sample group for scanning electron microscopy.

[0136] 6. Result analysis:

[0137] (1) Hair scanning differential scanning calorimetry (DSC) analysis results and analysis

[0138] The DSC curve of hair α-keratin shows an endothermic peak between 230°C and 250°C, labeled the α-helix peak. The peak temperature (Td) is defined as the denaturation temperature of the α-helix peak. The peak area (ΔHd) represents the denaturation enthalpy, which refers to the energy required for denaturation of the α-helix peak (heat absorbed per gram of dry hair). ΔHd is used to calculate RHC (relative helical content): RHC = 100 × (ΔHd sample / ΔHd control)%. The smaller the peak area in the sample, the smaller the RHC, indicating greater α-keratin damage. The mean peak temperature and mean peak area of the hair helix peak are shown in Table 6.

[0139] Table 6

[0141] It can be seen from the data in Table 6 that the pruning fruit oil prepared by the preparation method of the present invention has an excellent effect of protecting hair from heat damage, and the selected pressing temperature, the composition formula of the mixed soil and the processing temperature affect the heat protection effect.

[0142] (2) Scanning electron microscopy test results and analysis of hair scales

[0143] The electron microscope scanning images of the control group are as follows Figure 1-3 As shown (magnifications are 500 times, 1000 times, and 2000 times, respectively); the electron microscope scanning images of the sample group of Example 1 are shown as follows Figure 4-6 As shown (magnifications are 500 times, 1000 times, and 2000 times, respectively).

[0144] As can be seen from the figure, the cuticles of the control group's hair bundles are irregularly arranged, while the cuticles of the sample group's hair bundles are more regularly arranged. The degree of cuticle closure is different between the hair bundles treated with the product and those not treated with the product. This indicates that the utilising the utilising fruit oil prepared in this invention has a repairing effect on the cuticles (cuticle closure) of hair bundles damaged by hair dryers.

[0145] Test Example 5

[0146] Softening and repairing efficacy test:

[0147] 1. Test Purpose: To evaluate the effectiveness of prickle fruit oil in improving combability, detangling, smoothness, and repairing hair scales by testing the dry combing, wet combing, friction, and hair scale conditions of the test sample and control before and after treatment.

[0148] 2. Test samples:

[0149] Control group: cyclopentasiloxane (solvent control);

[0150] Sample group: 98 g of cyclopentasiloxane was weighed, and 2.0 g of the prickle oil prepared in Examples 1-6 and Comparative Examples 1-6 were added respectively, and the mixture was stirred and mixed to prepare a prickle oil sample with a concentration of 2%, which was set aside.

[0189] Table 7

[0190]

[0191]

[0192] It can be seen from the data in Table 7 that the pruning fruit oil prepared by the preparation method of the present invention has excellent hair softening and repairing effects, and the selected pressing temperature, the composition formula of the mixed soil and the processing temperature affect the softening and repairing effects.

[0193] The results of the hair scale repair test for the control group and the sample group of Example 1 are shown in the following figures: Figure 7 and Figure 8 As shown in the figure, the cuticles of normal hair are arranged from root to tip like fish scales from head to tail. When hair is damaged, the tail end of the cuticles will lift up and detach from the hair. The greater the lifting, the more the cuticles open and close. In severe cases, the entire cuticle will fall off the hair. The surface of the cuticle is relatively smooth. In normal hair, the cuticles are tightly arranged on the hair body, giving the hair a smooth and shiny appearance. When the cuticles lift up, open and close, or fall out, the hair becomes rough and loses its luster.

[0194] After the sample group was treated, the opening and closing of the hair scales was smaller, and the hair scales did not fall off; after the control group was treated, there was no obvious change in the opening and closing of the hair scales, and the hair scales did not fall off, indicating that the clavatica oil involved in the present invention has excellent effect of repairing hair scales.
