Description

Technical Field

[0001] The invention relates to the technical field of cosmetics, and in particular to a composite vegetable oil and a preparation method thereof. Background Art

[0002] In recent years, the concept of using oil to nourish the skin has become popular. This is because the sebum membrane and stratum corneum in our skin structure are both lipophilic and non-hydrophilic. Oil skin care products are easier to penetrate into the skin than water skin care products. Therefore, oil skin care products are more suitable for replenishing and strengthening the sebum membrane, thereby achieving the effect of moisturizing and protecting the skin.

[0003] Traditionally, it is believed that oily skin already has sufficient sebum secretion and does not need to be applied on the skin surface to increase the burden on the skin, but this view is not entirely correct. Although oily skin already has a lot of sebum secretion, some people have problems with over-cleansing or over-using oil-control products. In addition, long-term work in dry indoor environments such as air conditioning and heating aggravates water loss in the bottom layer of the skin, stimulating the sebaceous glands to secrete more oil to protect the skin, leading to an imbalance in skin oil secretion and damage to the skin barrier, which in turn causes skin problems such as peeling, allergies, enlarged pores, acne and blackheads. At this time, the skin needs to be nourished and protected by adding appropriate oils.

[0004] However, most of the skin care oils on the current market contain only a single plant oil component. We know that different plant oils have different skin care effects due to their unique ingredients and properties. A single plant oil component is difficult to meet the needs of oily skin with damaged barriers for multiple nutrients, which may lead to insignificant skin improvement effects. Composite plant oil products are often not suitable for skin with damaged barriers due to problems such as improper matching of plant oils or inappropriate addition amounts. For example, some plant oils may easily clog pores, causing skin problems such as acne and blackheads to become more serious. Some plant oils may be too light and cannot provide sufficient moisturizing effects after applying to the face. Some plant oils may stay on the skin for too long and absorb slowly, causing the skin to feel stuffy and affecting the use experience. Some plant oils may be too thick in texture, leaving a greasy feeling on the skin, aggravating the problem of unbalanced oil secretion on the skin surface. Therefore, developing a composite plant oil that can be suitable for oily skin with damaged barriers and effectively relieve abnormal skin oil secretion has become an important research direction in the field of cosmetic technology. Summary of the invention

[0005] In order to develop a composite vegetable oil suitable for oily skin with damaged barrier, the present application provides a composite vegetable oil and a preparation method thereof. The applicant is well aware that different vegetable oils have different skin care effects due to their unique ingredients and properties. The present application produces a significant synergistic effect in regulating skin oil secretion by rationally matching five vegetable oils, namely sunflower seed oil, olive oil, jojoba seed oil, palm fruit oil and sea buckthorn seed oil. Such a composite vegetable oil can not only repair abnormal skin oil secretion and maintain the water-oil balance of the skin, but also deeply moisturize the skin, solve the problem of skin dehydration, repair damaged skin barrier, and reduce the damage of the external environment to the skin. In addition, the composite vegetable oil also has antioxidant and anti-aging effects, which can effectively delay skin aging and keep the skin young.

[0006] In the first aspect, the present application provides a composite vegetable oil using the following technical solution:

[0007] A complex vegetable oil comprising sunflower seed oil, olive fruit oil, jojoba seed oil, mauritius fruit oil and sea buckthorn seed oil.

[0008] In the above technical solution, sunflower seed oil is used as the base oil, which is rich in linoleic acid and vitamin E. These ingredients not only have good moisturizing properties, but also can effectively promote the regeneration and repair of skin cells, laying a gentle and nourishing foundation for the composite plant oil. At the same time, sunflower seed oil also has excellent penetration and can quickly penetrate into the deep layers of the skin, helping the active ingredients of other plant oils to be better absorbed by the skin, thereby improving the overall skin care effect.

[0009] Olive oil is rich in natural ingredients such as olive polyphenols and unsaturated fatty acids, which can moisturize the skin and supplement nutrients. It can effectively reduce the damage of free radicals to the skin and promote skin metabolism. At the same time, olive oil has good ductility on the skin, which is beneficial to enhance the use experience of compound vegetable oil.

[0010] Jojoba seed oil is squeezed from jojoba seeds. The molecular arrangement of jojoba seed oil is similar to human fat, so it has excellent skin affinity and permeability. It can effectively lock in moisture and regulate sebum secretion, effectively improving the dryness and tightness of oily skin caused by excessive cleansing or oil control. At the same time, jojoba seed oil also has soothing and anti-inflammatory effects, which can effectively relieve facial discomfort.

[0011] Palmyra palm fruit oil is mild and safe. It is rich in oleic acid, linoleic acid, palmitic acid, carotenoids, vitamin E and vitamin C. It can deeply nourish the skin, enhance skin's elasticity and radiance, reduce the appearance of fine lines, and has a barrier repair effect on damaged skin.

[0012] The unique fatty acids in sea buckthorn seed oil can penetrate deep into the skin, repair damaged skin, help repair damaged skin, and restore a healthy radiance. At the same time, sea buckthorn seed oil is rich in vitamin C, vitamin E, flavonoids and other ingredients, which can help the skin resist damage from free radicals, inhibit skin inflammation, and delay skin aging.

[0013] This application uses a reasonable combination of five vegetable oils, namely sunflower seed oil, olive oil, jojoba seed oil, palm oil and sea buckthorn seed oil, to not only maximize the unique skin care advantages of each vegetable oil, but also achieve a significant synergistic effect in regulating skin oil secretion, meeting the unique needs of oily skin with damaged barriers for skin care products. Specifically, the synergistic effect between sunflower seed oil, olive oil, jojoba seed oil, palm oil and sea buckthorn seed oil is achieved through the complementarity and enhancement of their respective unique ingredients in the surface and deep layers of the skin. This synergistic mechanism is not only reflected in the regulation of skin oil secretion, but also involves multiple levels such as barrier repair, deep nourishment and anti-aging. First, sunflower seed oil and jojoba seed oil can reshape the sebum membrane and effectively balance oil secretion. Then, olive oil and palm fruit oil work together to enhance the skin barrier's resistance and water-locking ability and reduce external damage to the skin. Secondly, sea buckthorn seed oil can further cooperate with the effective ingredients in the compound plant oil to form a powerful repair network on the face, effectively resist external damage, penetrate deep into the skin, replenish necessary nutrients, and repair damaged skin in an all-round way, enhance skin elasticity and firmness, maintain the balance of skin oil secretion, and improve the overall health of the skin.

[0014] Preferably, the composite vegetable oil comprises, by mass percentage, 10%-20% olive oil, 5%-15% jojoba seed oil, 0.1%-1% palm fruit oil, 0.1%-1% sea buckthorn seed oil, and the remainder is sunflower seed oil.

[0015] In the above technical scheme, the present application limits the amount of each component in the composite vegetable oil, especially adjusts the addition amount of palmetto oil and sea buckthorn seed oil, thereby reducing production costs and ensuring the optimal synergistic effect of vegetable oil in the composite vegetable oil system to achieve the best skin care effect. At the same time, the trace addition of palmetto oil and sea buckthorn seed oil further improves the stability of the composite vegetable oil system, especially the low-temperature stability, avoids the solidification or stratification phenomenon that may occur in a low-temperature environment, and ensures the comfort and stability of the product.

[0016] Preferably, squalane and tocopherol are also included.

[0017] In the above technical scheme, squalane is a natural ingredient very similar to human sebum, and it has good moisturizing and anti-oxidation effects, can effectively repair the barrier function of skin, and make skin smoother, softer and more elastic. Tocopherol, i.e. vitamin E, is a fat-soluble vitamin, has antioxidant effect, can protect cells from free radical damage, prevent cell damage and aging, has a positive impact on skin health, and can slow down the aging process. The applicant has found through research that adding squalane and tocopherol on the basis of sunflower seed oil, olive fruit oil, jojoba seed oil, hair palm fruit oil and sea buckthorn seed oil can further lock skin moisture, enhance the barrier function of skin, enhance the absorption capacity of skin to composite plant oil, give play to better effect, and can also provide more comfortable skin feel, and consumers can feel smoother, moisturizing and light touch when using such plant composite oil.

[0018] Preferably, based on the mass percentage of the composite vegetable oil, it includes 20%-30% squalane and 0.1%-1% tocopherol.

[0019] In the above technical scheme, the present application limits the addition amount of squalane and tocopherol in the composite vegetable oil, thereby improving the stability of the composite vegetable oil system and further enhancing the synergistic effect of squalane, tocopherol and other raw materials in the composite vegetable oil, thereby jointly improving the skin's own moisturizing ability, resisting damage to the skin from the external environment, balancing the skin's oil secretion, and maintaining the skin in a healthy state.

[0020] Preferably, the composite vegetable oil comprises, by mass percentage, 10%-20% olive oil, 5%-15% jojoba seed oil, 0.1%-1% palm fruit oil, 0.1%-1% sea buckthorn seed oil, 20%-30% squalane, 0.1%-1% tocopherol, and the balance is sunflower seed oil.

[0021] In the above technical solution, the present application further limits the amount of each raw material added in the composite plant oil, so that the composite plant oil achieves a better synergistic effect in skin care. The precise ratio between the raw materials ensures that they can work together at different levels of the skin to form a comprehensive, multi-level skin care network.

[0022] Preferably, the composite vegetable oil comprises, by mass percentage, 15%-18% olive oil, 10%-14% jojoba seed oil, 0.2%-0.5% palmitole nut oil, 0.2%-0.4% sea buckthorn seed oil, 25%-29% squalane, 0.1%-0.2% tocopherol, and the balance is sunflower seed oil.

[0023] Preferably, the composite vegetable oil comprises, by mass percentage, 15% olive oil, 10% jojoba seed oil, 0.2% palm fruit oil, 0.2% sea buckthorn seed oil, 29% squalane, 0.2% tocopherol, and 45.4% sunflower seed oil.

[0024] In the above technical scheme, this application further adjusts the content of each raw material of the composite vegetable oil, so that the synergistic effect of the composite vegetable oil in regulating skin oil secretion is better, the barrier function of the skin is significantly enhanced, and better skin care effects are exerted, which is more in line with the unique needs of oily skin with damaged barrier for skin care products.

[0025] In a second aspect, the present application provides a method for preparing a composite vegetable oil using the following technical solution:

[0026] A preparation method of composite vegetable oil comprises: firstly heating sunflower seed oil, olive oil and jojoba seed oil to 40-45 DEG C, stirring and dispersing them uniformly, then adding other raw materials, stirring and dispersing them uniformly again, and obtaining composite vegetable oil.

[0027] In the above technical solution, the present application can ensure that various ingredients are fully mixed and exert the best skin care effect through the above simple and easy preparation method. The composite plant oil prepared in this way not only has multiple skin care effects, but also has good stability and is easy to store and use.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. The present application achieves a good synergistic effect through the combination of sunflower seed oil, olive oil, jojoba seed oil, mauritius fruit oil and sea buckthorn seed oil. This synergistic effect not only regulates the oil secretion of the skin, but also significantly enhances the repair and protection ability of the skin barrier, deeply nourishes and effectively resists aging, and especially meets the unique skin care needs of oily skin with damaged barrier.

[0030] 2. The present application reduces production costs while ensuring the best skin care effect of the composite vegetable oil by regulating the amount of sunflower seed oil, olive oil, jojoba seed oil, palm fruit oil, sea buckthorn seed oil, squalane, and tocopherol. In particular, the trace addition of palm fruit oil and sea buckthorn seed oil not only improves the stability of the system, but also enhances the comfort of use in a low temperature environment and avoids solidification or stratification.

[0031] 3. This application not only significantly enhances the barrier repair effect of the composite vegetable oil by adding squalane and tocopherol to the composite vegetable oil, thus bringing consumers a healthier skin condition, but also provides a more comfortable skin feel. When consumers use such a composite vegetable oil, they can feel a smoother, moisturizing and light touch.

[0032] 4. The composite plant oil of the present application is developed and designed to meet the unique skin care needs of oily skin with damaged barrier, meeting the unique skin care needs of oily skin with damaged barrier, and bringing new technological breakthroughs and market opportunities to the skin care industry.

[0077] Stability testing

[0078] Test sample: the composite vegetable oil of the above embodiments and comparative examples.

[0079] High temperature stability: Place the test sample at 45°C for 30 days, take it out, compare it with the sample at room temperature, observe the color and identify the odor changes.

[0080] Low temperature stability: Place the test samples in 5℃, 0℃, and -5℃ environments respectively, take them out after 12 hours, compare them with the samples placed at room temperature, and observe the changes in sample color and state.

[0081] The test results of the composite vegetable oils of Examples 1-6 and Comparative Examples 1-5 are shown in Table 5.

[0082] Table 5:

[0083]

[0084]

[0085] The test results of the composite vegetable oils of Examples 7-10 are shown in Table 6.

[0086] Table 6:

[0087]

[0088] The test results of the composite vegetable oils of Examples 11-14 are shown in Table 7.

[0089] Table 7:

[0090]

[0091] Combining the analysis of Examples 1-14, Comparative Examples 1-5 and Tables 5-7, it is not difficult to see that the examples have good stability and can withstand high temperatures of 45°C and low temperatures of 0°C.

[0092] Specifically combined with the analysis of Examples 7-14, Examples 7-10 fine-tune the amount of palmyra palm fruit oil, and Examples 11-14 fine-tune the amount of sea buckthorn seed oil. It can be seen that with the adjustment of the content of these two oils, although the high-temperature stability is not affected, under low temperature conditions, especially when the temperature drops to -5°C, the fluidity of the composite vegetable oil begins to deteriorate, and even solidifies in some extreme cases, and the color also changes slightly. This proves that under the premise of keeping the basic ratio of each raw material relatively stable, fine-tuning the amount of palmyra palm oil and sea buckthorn seed oil can significantly affect the physical stability of the composite vegetable oil.

[0093] In combination with Example 1 and Comparative Examples 1-5, in Comparative Examples 1-5, sunflower seed oil is replaced with sweet almond oil, olive oil is replaced with olive oil, jojoba seed oil is replaced with sweet almond seed oil, palm oil is replaced with argan oil, and sea buckthorn seed oil is replaced with grape seed oil. The composite vegetable oil of Example 1 can remain stable at low temperatures. It can be seen that the stability of the composite vegetable oil depends not only on the individual properties of each raw material, but also on the interaction between sunflower seed oil, olive oil, jojoba seed oil, palm oil, and sea buckthorn seed oil. Therefore, the applicant analyzes that only in a composite vegetable oil system such as sunflower seed oil, olive oil, jojoba seed oil, palm oil, and sea buckthorn seed oil, further fine-tuning the amount of palm oil and sea buckthorn seed oil can further improve the low-temperature stability of the composite vegetable oil.

[0094] Human trial effect testing

[0095] Test samples: composite vegetable oils of Examples 1-6 and Comparative Examples 1-5.

[0096] Subjects: Patients diagnosed with early mild acne by dermatologists, without systemic skin diseases, and not taking medications that affect the skin or undergoing facial beauty treatments in the past month, aged between 18 and 30 years old, a total of 110 people, divided equally into 11 groups.

[0097] Experimental method: The experiments were completed between June and August in a southern city. The subjects cleansed their faces with a non-effective cleanser every night, then applied the test samples and massaged their faces with the same massage technique for 10-15 minutes for 14 consecutive days.

[0098] Detection method: The subjects were placed in an indoor environment at 25°C and a relative humidity of 70%. A skin moisture meter (Corneometer CM825) was used to measure the moisture content of the stratum corneum of the cheek. A transepidermal water loss meter (Tewameter TM300) was used to measure the transepidermal water loss (TEWL) of the cheek. A skin oil meter (Sebumeter SM815) was used to measure the oil content of the cheek. A skin melanin and hemoglobin content tester (Mexameter MX18) was used to detect the hemoglobin content of the cheek. The results of the above detection indicators were averaged, and the change rates of the above detection indicators were calculated. The change rate (%) = (Tn detection value - T0 detection value) / T0 detection value * 100%, Tn = T7, T14. The test results are shown in Table 8.

[0099] After the trial, dermatologists evaluated the subjects' facial acne conditions. The evaluation results are shown in Table 9.

[0100] Table 8:

[0101]

[0102]

[0103] Table 9:

[0104]

[0105] Combining the analysis of Examples 1-6, Comparative Examples 1-5, and Tables 8 and 9, it can be seen that the skin condition of the subjects using the composite vegetable oils of Examples 1 to 6 was significantly improved, especially in terms of the five key indicators of moisture content, transepidermal water loss, oil content, hemoglobin content, and acne regression, all of which showed a positive trend of change.

[0106] Specifically combined with Example 1 and Comparative Examples 1-5, Comparative Examples 1-5 respectively replace sunflower seed oil with sweet almond oil, olive oil with olive oil, jojoba seed oil with sweet almond seed oil, argan oil with argan oil, and seabuckthorn seed oil with grape seed oil. It is obvious that the composite vegetable oil in Example 1 improves skin moisture content, improves skin barrier function, balances skin oil secretion, and resists skin inflammation. It has a more significant effect on improving skin acne. It can be seen that the composite vegetable oil in Example 1 is through the compounding of sunflower seed oil, olive oil, jojoba seed oil, argan oil, and seabuckthorn seed oil and the interaction between them, which not only significantly improves the skin's moisturizing performance and enhances the skin barrier function, but also effectively regulates the skin oil balance and reduces skin inflammation, thereby improving the skin condition of the subject in many aspects, so that the subject's facial acne is effectively eliminated.

[0107] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
