Description

Technical Field

[0001] The present application relates to the field of sunscreen external products, and more specifically, to a highly effective sunscreen cosmetic and a preparation method thereof. Background Art

[0002] As global environmental pollution intensifies and the atmospheric ozone layer is damaged, the amount of ultraviolet radiation reaching the earth's surface has risen sharply. Ultraviolet rays have a wide and far-reaching impact on the skin, not only causing immediate effects such as sunburn and tanning, but also leading to long-term damage such as photoaging, which manifests as skin pigmentation, wrinkle formation, dryness and desquamation, rough texture, sagging, and increased spots. At the same time, it seriously threatens human health, causing a significant increase in the incidence of solar dermatitis and skin cancer worldwide.

[0003] As a key type of functional cosmetics, the core function of sunscreen cosmetics is to effectively alleviate skin damage caused by the sun by absorbing or scattering (reflecting) ultraviolet rays. Although traditional sunscreen cosmetics can resist ultraviolet rays to a certain extent, sunscreens themselves are often irritating and long-term use may have a negative impact on the skin. Physical sunscreens are relatively mild, but their user experience may be poor, such as bringing a greasy and heavy feeling, and are not suitable for people with metal allergies. Chemical sunscreens are known for their excellent sun protection effect, but some ingredients may be irritating.

[0004] Therefore, there is room for improvement. Summary of the invention

[0005] In order to solve the above problems, the present application provides a high-efficiency sunscreen cosmetic and a preparation method thereof. The high-efficiency sunscreen cosmetic provided in the present application has good sunscreen effect, low irritation, anti-inflammatory, and multiple functions.

[0006] In the first aspect, the present application provides a highly effective sunscreen cosmetic, which adopts the following technical solution: A highly effective sunscreen cosmetic comprising the following components in percentage by mass: Component A: 1.5-4% emulsifier, 3-8% emollient, 15-20% sunscreen, 0.1-0.5% antioxidant, 1-3% polydimethylsiloxane; Sunscreens include ethylhexyl methoxycinnamate, titanium dioxide, benzophenone-3, 4-methylbenzylidene camphor, butyl methoxydibenzoylmethane; Component B: 0.01-1% film former, 10-15% moisturizer, 0.01-0.05% chelating agent, 0.01-0.1% thickener, 0.3-0.6% preservative A, water; Component C: 0.05-0.15% triethanolamine; Component D: 0.1-1% gentian extract, 0.1-1% oat extract, 0.1-1% tomato extract.

[0007] The high-efficiency sunscreen cosmetics provided in the present application, by combining preferred sunscreen agents and specific plant extracts (gentian extract, oat extract, tomato extract), greatly reduce the irritation of high-efficiency sunscreen cosmetics while directly maintaining a high sunscreen effect, and improve the skin's resistance to ultraviolet rays, thereby indirectly improving the sunscreen effect.

[0008] Specifically, gentian extract is rich in antioxidant ingredients, such as flavonoids, which can effectively remove or reduce reactive oxygen free radicals caused by ultraviolet radiation and protect skin cells from oxidative damage. At the same time, ingredients such as gentiopicroside in gentian have anti-inflammatory effects, which can inhibit the increase in capillary permeability, reduce the production of histamine, and weaken the inflammatory response of the skin caused by irritation. In addition, gentian extract can also promote the regeneration and repair of skin cells, help restore the integrity of the skin barrier function, and improve the skin's resistance to ultraviolet rays.

[0009] Oat extract can maintain skin moisture, relieve dry skin, and enhance the stability of skin barrier function. At the same time, antioxidant substances such as avenanthramide in oat extract have strong antioxidant activity, which can inhibit the generation and chain reaction of free radicals and reduce the damage caused by free radicals to tissues. In addition, oat extract can also promote the renewal and metabolism of skin cells, help maintain the normal structure and function of the skin, and further enhance the health of the skin.

[0010] Tomato extract can capture free radicals, neutralize their excessive activity, and protect cells from oxidative damage. Lycopene also has the ability to inhibit the production and release of inflammatory mediators, which can reduce the inflammatory response of tissues and reduce the expression of pro-inflammatory cytokines, thereby exerting an anti-inflammatory effect.

[0011] When gentian extract, oat extract, and tomato extract work together in sunscreen products, they can form a powerful antioxidant network, synergistically remove free radicals, and protect skin cells from oxidative damage. At the same time, they can also synergistically inhibit skin inflammatory responses and reduce skin discomfort caused by ultraviolet radiation or other external factors. In addition, these extracts can also promote the recovery and enhancement of skin barrier function, improve skin resistance to ultraviolet rays, and make the skin healthier, smoother, and younger.

[0012] Preferably, according to the mass percentage of the high-efficiency sunscreen cosmetic, the sunscreen agent includes 5-10% ethylhexyl methoxycinnamate, 2-5% titanium dioxide, 1-3% benzophenone-3, 1-3% 4-methylbenzylidene camphor, and 1-3% butyl methoxydibenzoylmethane.

[0013] By adopting the above technical scheme, the specific selection and dosage of sunscreen agents are further limited, providing comprehensive sun protection for the skin and effectively reducing irritation. Ethylhexyl methoxycinnamate can effectively absorb ultraviolet rays in the UVB band and reduce the risk of sunburn. Titanium dioxide, as a physical sunscreen, can reflect and scatter ultraviolet rays, protect the skin from UVA and UVB damage, and has high safety. Benzophenone-3 can widely absorb ultraviolet radiation in the A and B segments and is suitable for strong sun protection index. 4-Methylbenzylidene camphor is also an effective ultraviolet absorber. Butyl methoxydibenzoylmethane can absorb the UVA band and enhance the sunscreen effect.

[0014] Preferably, according to the mass percentage of the high-efficiency sunscreen cosmetic, the gentian extract is 0.3-0.5%, the oat extract is 0.3-0.5%, and the tomato extract is 0.6-0.8%.

[0015] By adopting the above technical scheme, the dosage relationship of gentian extract, oat extract and tomato extract in the system is further limited, so that the synergistic effect of the three can be more fully exerted, the anti-inflammatory effect is further enhanced, the skin's resistance to ultraviolet rays is improved, and the sun protection effect is better.

[0016] Preferably, the D component also includes oat β-glucan, palmitoyl tripeptide-5, and hydrolyzed yeast protein.

[0017] Preferably, according to the mass percentage of the high-efficiency sunscreen cosmetic, oat β-glucan is 0.1-1%, palmitoyl tripeptide-5 is 0.1-1%, and hydrolyzed yeast protein is 0.1-1%.

[0018] By adopting the above technical solution, oat β-glucan, palmitoyl tripeptide-5 and hydrolyzed yeast protein are further added. Oat β-glucan can enhance skin immunity and resist UV damage, while also having moisturizing and anti-aging effects. Palmitoyl tripeptide-5, as a signal peptide, can promote the synthesis of skin collagen and elastin, making the skin younger and more elastic. Hydrolyzed yeast protein is rich in nutrients such as amino acids and peptides, which can promote skin cell metabolism, enhance skin regeneration and repair capabilities, and has strong moisturizing properties, which helps keep the skin hydrated and prevent dryness and roughness. These ingredients work together to enhance the skin care effect of sunscreen products.

[0019] Preferably, the emollient comprises a mixture of one or more of C12-15 alcohol benzoate, jojoba oil, and 1618 alcohol.

[0020] Preferably, according to the mass percentage of the high-efficiency sunscreen cosmetic, C12-15 alcohol benzoate is 3-5%, jojoba oil is 0.5-1.5%, and 1618 alcohol is 0.1-1%.

[0021] By adopting the above technical solution, the types and dosage of emollients are further limited, and the coordination effect of C12-15 alcohol benzoate, jojoba oil and 1618 alcohol in sunscreen products is fully exerted.

[0022] C12-15 alcohol benzoate can bring a refreshing skin feel, reduce greasiness, and make sunscreen products easy to apply and spread. Jojoba oil, with its natural moisturizing and softening properties, enhances the skin's moisture and comfort. 1618 alcohol further enhances the product's softness and stability. The combination of the three not only makes the sunscreen product more moisturizing and refreshing, but also improves the overall effect of the product, making gentian extract, oat extract, and tomato extract easier to absorb and play a role.

[0023] A highly effective sunscreen cosmetic comprising the following components in percentage by mass: Component A: 1.5-4% emulsifier, 3-8% emollient, 15-20% sunscreen, 0.1-0.5% antioxidant, 1-3% polydimethylsiloxane; Emulsifiers include 0.3-0.7% glyceryl stearate PEG-100 stearate, 0.5-1.5% potassium cetyl phosphate, 0.3-0.8% glyceryl stearate citrate, 0.5-1% Sethic G57; Emollients include 3-5% C12-15 alcohol benzoate, 0.5-1.5% jojoba oil, 0.1-1% 1618 alcohol; Sunscreens include 5-10% ethylhexyl methoxycinnamate, 2-5% titanium dioxide, 1-3% benzophenone-3, 1-3% 4-methylbenzylidene camphor, 1-3% butyl methoxydibenzoylmethane; Antioxidants include 0.01-0.2% tocopheryl acetate, 0.1-0.3% bisabolol; Component B: 0.01-1% film former, 10-15% moisturizer, 0.01-0.05% chelating agent, 0.01-0.1% thickener, 0.3-0.6% preservative A, water; The film former includes 0.01-0.2% acrylic acid (ester) / C10-30 alkyl acrylate cross-linked polymer, 0.01-0.3% ammonium acryloyldimethyltaurate / VP copolymer; Humectants include 5-10% glycerin, 5-10% propylene glycol; Chelating agents include EDTA-2 sodium and EDTA-4 sodium; Thickeners include xanthan gum, gelatin, gum arabic, and agar; Preservative A includes p-hydroxyacetophenone; Component C: 0.05-0.15% triethanolamine; Component D: 0.1-1% gentian extract, 0.1-1% oat extract, 0.1-1% tomato extract, 0.1-1% oat β-glucan, 0.1-1% palmitoyl tripeptide-5, 0.1-1% hydrolyzed yeast protein; Component E: 0.01-0.1% flavoring agent, 0.5-1% preservative B; Fragrance agents include rose essential oil, jasmine essential oil, and orange essential oil; Preservative B includes hexylene glycol.

[0024] In a second aspect, the present application provides a method for preparing a highly effective sunscreen cosmetic, using the following technical solution: A method for preparing a highly effective sunscreen cosmetic comprises the following steps: Step 1: Stir the raw materials of component A at 80-85°C until they are completely dissolved to obtain phase A; The raw materials of component B are stirred uniformly at 80-85°C to obtain phase B; Step 2: Mix phase A and phase B to obtain phase AB; Step 3: Cool down to 68-72°C, stir and mix component C with phase AB to obtain phase ABC; Step 4: Cool down to 38-43°C, mix the remaining raw materials with ABC evenly to obtain a highly effective sunscreen cosmetic.

[0025] In summary, this application has the following beneficial effects: 1. This application achieves a perfect combination of high sunscreen effect and low irritation by optimizing sunscreen agents and specific plant extracts (gentian extract, oat extract, tomato extract). These plant extracts are rich in natural ingredients, mild and non-irritating, can greatly reduce the irritation of sunscreen products to the skin, reduce discomfort during use, and are suitable for sensitive skin.

[0026] 2. The combination of cholla extract, oat extract and tomato extract exerts a powerful anti-inflammatory effect, inhibits skin inflammatory response, reduces the production of histamine, and reduces capillary permeability, thereby reducing skin redness, swelling, stinging and other discomforts caused by ultraviolet radiation or other external factors.

[0027] 3. Through the combined action of gentian extract, oat extract and tomato extract, the skin's resistance to ultraviolet rays can be significantly improved, the regeneration and repair of skin cells can be promoted, and the integrity of the skin barrier function can be quickly restored. It can not only effectively resist the direct damage of ultraviolet rays, but also reduce skin aging, pigmentation and other problems caused by ultraviolet rays, and indirectly enhance the sunscreen effect.

[0080] Performance testing 1. Anti-inflammatory effect: RAW264.7 macrophages (1×10 4 / well) in a 96-well plate. 1 mL of DMEM medium containing 10% fetal bovine serum was added to each well and cultured in a 5% CO2 incubator (37°C) for 4 h. The cells were then randomly divided into blank group (cells + medium), LPS group (1 μg / mL LPS + cells), and experimental group (high-efficiency sunscreen cosmetics + 1 μg / mL LPS + cells), with 3 replicates in each group.

[0081] The high-efficiency sunscreen cosmetics used in the experimental group are derived from the high-efficiency sunscreen cosmetics of Examples 1-6 and Comparative Examples 1-4.

[0082] The mass concentration of RAW264.7 macrophages treated with high-efficiency sunscreen cosmetics in the experimental group was 50 μg / mL, and LPS with a final mass concentration of 1 μg / mL was added to stimulate the cells. After 24 hours, the supernatant was used to detect the expression of inflammatory factor TNF-α using an ELISA kit, and the results are recorded in Table 2.

[0083] 2. Ultraviolet resistance: 100 volunteers were selected and randomly divided into 10 groups, one group corresponding to a high-efficiency sunscreen cosmetic in Examples 1-6 and Comparative Examples 1-4.

[0084] On the first day of the test, a hemoglobin tester was used to measure the red pigmentation of the cheeks. This was the initial red pigmentation test value.

[0085] Then irradiate for 5 minutes under the condition of UV index level 5, and measure the red pigmentation of the cheeks again. This is the red pigmentation test value after the original irradiation.

[0086] Rest for one day (i.e. the second day of the test), ensure that the skin is soothed and not red, apply high-efficiency sunscreen cosmetics on the cheeks, and after the film is formed, irradiate the skin under the condition of UV index 5 for 5 minutes, and measure the red pigmentation of the cheeks again. This is the red pigmentation test value after one use and irradiation.

[0087] Use high-efficiency sunscreen cosmetics continuously for 28 days. On the 28th day, apply high-efficiency sunscreen cosmetics on the cheeks. After the film is formed, irradiate for 5 minutes under the condition of UV index level 5, and measure the red pigment of the cheeks again. This is the red pigment test value after 28 days of use and irradiation.

[0088] The red pigment change rate was calculated according to the following formula, and the average value of the volunteers in the same group was taken as the group data and recorded in Table 2.

[0089] Table 2 According to the comparison of the test results in Table 2, the LPS group was significantly higher than the blank group, indicating that the modeling was successful. However, Examples 1-6 and Comparative Examples 1-4 showed a downward trend compared with the LPS group, indicating that the high-efficiency sunscreen cosmetics of Examples 1-6 and Comparative Examples 1-4 all had certain anti-inflammatory effects. Further comparison of the data showed that although the high-efficiency sunscreen cosmetics of Comparative Examples 1-4 had anti-inflammatory effects, their effects were significantly less significant than those of Examples 1-6, with a significant gap.

[0090] In the test of ultraviolet resistance, after the first use of the high-efficiency sunscreen cosmetics of Examples 1-6, the redness of the face was significantly improved compared with not using the high-efficiency sunscreen cosmetics. After continuous use for 28 days, the skin's ability to resist ultraviolet rays was improved, and it was less likely to turn red than in the initial stage, and skin inflammation and allergies were alleviated, showing a good sunscreen effect.

[0091] The red pigment change rate of the high-efficiency sunscreen cosmetics of Examples 1-6 after one-time use and 28-day use was lower than that of Comparative Examples 1-4, indicating that the high-efficiency sunscreen cosmetics of Examples 1-6 have more significant improvement effects. In other words, the special combination of gentian extract, oat extract, and tomato extract has a good synergistic effect, improves the skin from multiple dimensions, and enhances the sunscreen effect.

[0092] Regarding Examples 5 and 6: Example 5 is based on Example 1, but oat β-glucan, palmitoyl tripeptide-5, and hydrolyzed yeast protein are omitted. Example 6 is based on Example 1, but the specific type and dosage of the emollient are changed. According to the comparison of the test results in Table 2, although the effects of Examples 5 and 6 in all aspects are maintained at a good level, there is a certain gap between them and Example 1. This shows that if oat β-glucan, palmitoyl tripeptide-5, and hydrolyzed yeast protein can be further added, or the specific type and dosage of the emollient can be limited, the synergistic effect of gentian extract, oat extract, and tomato extract can be better exerted, so that the high-efficiency sunscreen cosmetics have better performance.

[0093] 3. Irritation: Follow up the volunteers who have undergone the UV resistance test to observe whether they have redness, rash, pimples, etc. after using high-efficiency sunscreen cosmetics for 24 hours.

[0094] Results: All volunteers showed no local irritation reactions such as redness, rash, and pimples on their skin, indicating that high-efficiency sunscreen cosmetics are safe and have no adverse reactions.

[0095] 4. Stability: Cold resistance stability test (48°C, 24h): The high-efficiency sunscreen cosmetics of Examples 1-6 and Comparative Examples 1-4 all passed the test.

[0096] Cold resistance stability test (-15°C, 24h): The high-efficiency sunscreen cosmetics of Examples 1-6 and Comparative Examples 1-4 all passed the test.

[0097] 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.
