Description

Technical Field

[0001] The invention relates to the field of daily chemical products, and in particular to a natural vegetable oil composition and a preparation method and application thereof. Background Art

[0002] Modern people are exposed to excessive stress, irregular diet and external environment caused by inhalable particulate matter, and have a variety of skin diseases such as acne, accelerated aging, and lack of moisture. These problems are caused by the damage of the skin protective film due to insufficient skin moisture. Therefore, the solutions to these problems include hydration and repair, and the use of cosmetics is one of the means of hydration and repair. In the early stage of the development of human cosmetics, natural products (animal and plant resources, minerals, etc.) were used as cosmetics. With the advancement of science, people found that the use of artificially synthesized chemicals is easier to obtain than natural products, and the price may be lower. At the same time, it can achieve certain skin care effects in many aspects, so they abandoned natural cosmetics and turned to chemical products. Then, since the use of chemical products, the toxicity, irritation and allergic problems of chemical drugs have gradually emerged. Its long-term use effect and safety issues have caused people's concerns. In addition, environmental protection issues caused by product industry have also followed. Therefore, in order to pursue natural, non-toxic and pollution-free products, people are trying their best to eliminate or reduce the side effects of chemical products, and at the same time, they will also pay more attention to natural plant raw materials with small side effects, high safety, and multiple physiological effects.

[0003] At present, with the strict requirements for cosmetics, if new cosmetic products want to continue to claim that the products have moisturizing effects, then the amount of raw materials or ingredients with moisturizing effects added to the formula must reach the content confirmed in the public literature. Otherwise, the product needs to be tested for moisturizing effects, which undoubtedly increases the development cost of the product in terms of cost and time. Commonly used moisturizers in cosmetics include polyol moisturizers, amide moisturizers, lactic acid and sodium lactate, sodium pyrrolidone carboxylate, glucose ester moisturizers, collagen (protein) moisturizers, chitin derivatives and deacetylated chitosan moisturizers. At present, polyol moisturizers such as glycerol and butylene glycol are more commonly used in cosmetics. First, the price of such raw materials is cheap, and second, in the public literature, the moisturizing effect content of such raw materials has been tested and certified to be effective, which can exempt the product from re-testing the moisturizing effect. However, although experiments have found that some oils and fats from natural sources also have certain moisturizing effects, there are few data on their efficacy content that have been tested and certified in public literature, and specific efficacy content data cannot be found for many ingredients. In particular, according to current literature and research data, the amount of a single oil raw material used as a moisturizer in cosmetics to achieve moisturizing effects is higher than that of polyol moisturizers such as glycerin and butylene glycol. For non-high-content oil formulas, it is difficult to add oil moisturizers. It is difficult to achieve the effective addition amount in actual formula development while taking into account stability and usability. Therefore, the current use of oils and fats from natural sources in cosmetics is subject to certain restrictions. Summary of the invention

[0004] The purpose of the present invention is to overcome one or more deficiencies in the prior art and to provide a new natural plant oil composition that can achieve both moisturizing effect and skin repair function with a relatively small addition amount, so as to overcome the problems existing in the prior art.

[0045] Based on a large number of experimental studies, the inventors of the present invention accidentally combined sunflower seed oil, jojoba seed oil, grape seed oil and camellia seed oil from natural plant sources during the experiment, and obtained unexpected moisturizing effect and skin repair effect. Compared with their individual or partial combinations, they have significantly better and more balanced effects, especially, only a small amount of addition can obtain significant moisturizing and skin repair effects, which is conducive to adding and using in cosmetics, without the need to use too much emulsifier for additional emulsification and dispersion, with good user experience and good stability, avoiding the irritation that may be caused by the use of additional emulsifiers; experimental results show that the natural plant oil composition composed of the above four components of the present invention has a long-lasting moisturizing effect, can form a partially occluded liquid film on the surface of the skin, and quickly diffuse into the gaps between the stratum corneum cells to soften the tissue, thereby playing an effective role. It has the dual effects of effective moisturizing and lubricating the skin, and can also achieve significant improvements in skin repair tests, for example, it can greatly improve the skin's transepidermal water loss rate; analysis shows that it may be that an unexpected synergistic effect is produced between them, so that their respective moisturizing ingredients and repairing ingredients can maximize their corresponding effects, and cooperate with each other, so that the effective ingredients can be delivered to specific parts such as the skin surface and delivered quickly; in fact, there are many natural plant oils with moisturizing ingredients or repair effects, but how to maximize the effects of their ingredients or even exert effects beyond their own limitations has always been the goal pursued by those skilled in the art. Based on experiments and research, the inventors of the present invention proposed a composition of four specific natural plant oils of the present invention, which achieved better moisturizing and repairing effects than single or partially combined oil raw materials at the same content.

[0048] The invention provides a natural plant oil composition which can achieve excellent moisturizing effect and skin repairing effect in cosmetics with a small addition amount, and comprises a combination of sunflower seed oil, jojoba seed oil, grape seed oil and camellia seed oil.

[0049] Sunflower Seed Oil

[0050] The main components of sunflower seed oil are unsaturated fatty acids (including linoleic acid, oleic acid and trace amounts of arachidonic acid) and saturated fatty acids (including palmitic acid, stearic acid and behenic acid), of which unsaturated fatty acids account for the majority. Some studies have shown that the most important essential fatty acid in human nutrition is linoleic acid, which can be converted into 20 carbon atoms and arachidonic acid containing four double bonds in the body. The body mainly uses essential fatty acids to synthesize phospholipids, which are components of all cell structures, especially mitochondria. If linoleic acid is lacking, the mitochondrial structure will change, and skin lesions (dry skin, scaly hypertrophy) caused by water metabolism disorders will occur at first. If severe metabolic disorders occur, it may even cause death. At the same time, linoleic acid is also an important substance for maintaining the softness, elasticity and activity of cell membranes. It plays an important role in maintaining balance and lowering serum cholesterol in human metabolism and regulating blood pressure.

[0051] Jojoba Oil

[0052] Jojoba oil (also known as jojoba seed oil) is extracted from the fruit kernel of the Simmondsia chinensis tree. Its fatty acids are roughly composed of 11-eicosenoic acid, 13-eicosenoic acid, oleic acid, palmitoleic acid, and saturated fatty acids (mainly palmitic acid). Unlike other natural oils, it is not a fatty acid triglyceride, but an ester composed of long straight-linked monounsaturated fatty acids and long straight-chain monounsaturated fatty alcohols (i.e., a long-chain liquid wax ester). Jojoba oil has good cold or hot stability, strong antioxidant properties, and little viscosity change when the temperature changes. It is easily absorbed by the skin and is miscible with sebum. It is a good emollient. The oil film it forms is different from mineral oil. It can pass through evaporated water and can also control water loss. A large number of safety and toxicology tests have confirmed that jojoba oil is very safe to use as a cosmetic oil, does not produce acne and antigens, and can alleviate the symptoms of psoriasis. Studies on transepidermal absorption have shown that it can quickly penetrate into the skin, and this absorption is obviously carried out through pores and hair follicles.

[0053] Grapeseed Oil

[0054] Grape seed extract (also known as grape seed oil) is one of the most effective antioxidants found in plants so far. In vivo and in vitro tests have shown that the antioxidant effect of grape seed extract is 30-50 times that of vitamin C and vitamin E. Many researchers at home and abroad have found through experiments that grape seed extract has multiple functions such as preventing atherosclerosis, anti-coagulation, increasing high-density lipoprotein or high-density lipoprotein cholesterol, inhibiting the oxidation of low-density lipoprotein, scavenging free radicals, and preventing cancer and tumors. Grape seeds are grape seeds obtained by separating the stalks, skins and pulps of grapes. They contain a variety of amino acids, fatty acids, polyphenols and vitamins E, K, Ca, P, Mg, Fe, Mn and other substances. Amino acids are mainly glutamic acid and glycine, fatty acids are mainly linoleic acid, palmitic acid, stearic acid, linolenic acid, etc., and polyphenols include phenolic acids, flavonoids, proanthocyanidins, resveratrol, anthocyanins and tannins. Grape seed oil is a fat product extracted from grape seeds. Grape seeds contain 10% to 14% fat, which has the effects of anti-oxidation, dilation of blood vessels and lowering cholesterol. Studies have found that the VE in grape seed oil has a significant antioxidant effect. Grape seeds are rich in polyphenols, a natural antioxidant. For example, adding grape seed products to facial masks can enhance the whitening effect; adding an appropriate amount of grape seed oil to shampoo can improve the antioxidant capacity.

[0055] Tea seed oil

[0056] Camellia seed oil is a non-drying oil extracted from the seeds of the Camellia plant of the Theaceae family. It is also known as tea seed oil, tea tree oil or camellia oil. Its natural ratio and composition of fatty acids are basically the same as those of olive oil, and it enjoys the reputation of "Oriental Olive Oil". Camellia seed oil is rich in cosmetic acids (generally referring to oleic acid and linoleic acid containing double bonds and their triglycerides), camellia glycosides, tea polyphenols, phospholipids, saponins, tannins, phytosterols, natural tocopherols and squalane. Experimental results show that the ultraviolet absorption effect of camellia seed oil is significantly better than that of aloe vera oil and olive oil, and it can achieve a very good sunscreen effect when combined with a simple physical sunscreen agent, nano-titanium dioxide.

[0057] The present invention unexpectedly combines the above four natural plant-derived oils. Practice shows that they have synergistic moisturizing and repairing effects. At the same content, they achieve better moisturizing and repairing effects than a single oil raw material or other combinations.

[0058] The composition of the present invention can have a repairing effect that is superior to that of conventional polyol moisturizers while showing a moisturizing effect similar to that of conventional polyols.

[0059] The combination of the present invention is a natural plant-derived ingredient with little side effect, high safety, simple preparation method, little impact on the environment, conforms to the ESG (Environmental, Social and Governance) concept, and is beneficial to consumer experience.

[0060] The above scheme is further described below in conjunction with specific embodiments; it should be understood that these embodiments are used to illustrate the basic principles, main features and advantages of the present invention, and the present invention is not limited to the scope of the following embodiments; the implementation conditions adopted in the embodiments can be further adjusted according to specific requirements, and the implementation conditions not specified are usually the conditions in conventional experiments.

The TEWL improvement rate of the glycerol, propylene glycol and butylene glycol trial products (application comparison examples 1-3) after 8 hours was 12-20%, and the repair effect was the lowest; the TEWL improvement rate of the single raw material trial products of sunflower seed oil, jojoba seed oil, grape seed oil and camellia seed oil (application comparison examples 4-7) after 8 hours was 27-37%, and the repair effect was better than that of the polyol trial products; the TEWL improvement rate of the trial products when three of the raw materials of sunflower seed oil, jojoba seed oil, grape seed oil and camellia seed oil were selected for compounding (application comparison examples 8-11) after 2 hours was 27.5-32.5 %, the TEWL improvement rate after 4h was 14-30%, the TEWL improvement rate after 6h was 34-40.5%, and the TEWL improvement rate after 8h was 42-46%, and the repair effect was better than that of the trial product made of single vegetable oil; when the four vegetable oils were compounded together, the TEWL improvement rate of the trial product (Application Examples 1-4 of the present invention) was 32-38% after 2h, 34-36% after 4h, 38-44% after 6h, and 47-48.5% after 8h, and the repair effect reached the highest. When olive oil and avocado oil with similar linoleic acid content are used to replace camellia seed oil, or macadamia seed oil is used to replace jojoba seed oil, the TEWL improvement rate of the trial products (comparative application examples 12-14) after 8 hours is 32-35%, which is lower than the improvement rate of the raw material trial products of the present invention, indicating that their repair effect is weaker than that of the raw material of the present invention; in addition, the timely repair effect and the long-term repair effect of comparative application examples 8-11 are far inferior to those of the application example compositions of the present invention.
