Description

Technical Field

[0001] This invention relates to a sunscreen compound composition and its preparation method, and more particularly to a broad-spectrum sunscreen ethylhexyltriazine compound composition and its preparation method. Background Technology

[0002] As people increasingly value skin health, sunscreen products have become an essential part of daily skincare. Their core function is to block UVB and UVA rays from damaging the skin, reducing sunburn, photoaging, and pigmentation. Currently, most sunscreen compositions on the market are based on a single sunscreen agent or a simple combination of sunscreen agents. While they can achieve basic sun protection, they still have many technical limitations.

[0003] Ethylhexyltriazine, a common broad-spectrum sunscreen agent, can absorb both UVB and UVA. However, when used alone, its sun protection strength and durability are limited, making it difficult to meet the needs of daily outdoor sun protection for extended periods. Existing sunscreen compositions often focus only on sun protection function without forming a synergistic sun protection system. This can easily lead to problems such as incomplete coverage of sun protection wavelengths, poor stability of sunscreen agents, and rapid decline in sun protection effect after sun exposure. It is difficult to resolve the contradiction between sun protection effect and gentleness and durability.

[0004] Therefore, there is an urgent need to develop a broad-spectrum, long-lasting sun protection compound composition of ethylhexyl triazine ketone to solve the aforementioned technical problems existing in the prior art. Summary of the Invention

[0005] To address the shortcomings of the aforementioned technologies, this invention provides a broad-spectrum sunscreen ethylhexyl triazine ketone compound composition and its preparation method.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is: a broad-spectrum sunscreen ethylhexyl triazine ketone compound composition, comprising the following components by weight: Ethylhexyl triazine 2.0-8.0 parts, compound sunscreen 3.0-10.0 parts, emulsifier 1.0-5.0 parts, emollient 2.0-8.0 parts, stabilizer 0.1-1.0 parts, moisturizer 5.0-15.0 parts, preservative 0.1-0.5 parts, repair and synergistic component 0.02-2.0 parts, balance deionized water; The repair and enhancement component is a mixture of photolyase and collagen, with a mass ratio of 1:1-1.5. The collagen is composed of type I collagen, type III collagen and type II collagen in a mass ratio of 12-15:1-5:80-87. The amount of photolyase added is 0.01-0.8 parts, and the amount of collagen added is 0.01-1.2 parts.

[0007] Preferably, the compound sunscreen agent is a mixture of diethylamino hydroxybenzoyl hexyl benzoate and bis-ethylhexyloxyphenol methoxyphenyl triazine, with a mass ratio of 1:1.2-2.0.

[0008] Preferably, the emulsifier is a mixture of hydrogenated lecithin, phytosterol and squalene, with a mass ratio of 3:2:1-1.5.

[0009] Preferably, the emollient is a mixture of isononyl isononanoate and shea butter in a mass ratio of 2:1.

[0010] Preferably, the stabilizer is at least one of polyhydroxystearic acid or occrylene.

[0011] Preferably, the humectant is a mixture of glycerin and butylene glycol in a mass ratio of 3:2.

[0012] Preferably, the preservative is a mixture of hexanediol and ethylhexylglycerin in a mass ratio of 2:1.

[0013] A method for preparing a broad-spectrum sunscreen ethylhexyl triazine ketone compound composition includes the following steps: Step S1: Preparation of aqueous phase: Add humectant and preservative to deionized water, stir evenly, heat to 70-85℃, continue stirring until completely dissolved, and keep warm for later use; Step S2, Preparation of oil phase: Add ethylhexyl triazine ketone, compound sunscreen agent, emulsifier, emollient and stabilizer to the oil phase pot, stir evenly, heat to 75-80℃, and continue stirring until all components are completely dissolved and there are no crystal particles. Keep warm for later use. Step S3, Primary Emulsification: Slowly add the oil phase to the aqueous phase while stirring at a speed of 300-500 r / min for 15-20 min. Then homogenize 2-3 times with a homogenizer, each time for 3-5 min at a speed of 2000-3000 r / min, to form a uniform and fine primary emulsion. Step S4, Cooling and Addition of Active Components: Slowly cool the primary emulsion to 35-45°C while continuously stirring at a speed of 100-200 r / min; then add the repair and synergistic components and continue stirring for 5-8 min to ensure that the repair and synergistic components are evenly dispersed in the primary emulsion to obtain a mixed emulsion. Step S5, let it stand and set: Cool the mixed emulsion naturally to room temperature, let it stand for 12-24 hours, filter to remove impurities, and obtain the broad-spectrum sunscreen ethylhexyl triazine ketone compound composition.

[0014] In steps S1 and S2, the heating process uses water bath heating with a temperature control accuracy of ±2℃; in step S3, the rate at which the oil phase is added to the water phase is 5-10 mL / min; in step S5, the cooling process uses a combination of natural cooling and water bath cooling.

[0015] The application of a sunscreen composition in skin care or cosmetic products.

[0016] Ethylhexyltriazine can absorb both UVB and UVA rays, making it the core component for achieving broad-spectrum sun protection in the composition. It can effectively block direct UV radiation to the skin, reducing problems such as skin redness, sunburn, and aging caused by UV rays, and is the core carrier of sun protection function.

[0017] Diethylamino hydroxybenzoyl hexyl benzoate has a strong absorption capacity for UVA (long-wave ultraviolet radiation), which can make up for the lack of UVA protection of single sunscreen agents and reduce problems such as skin photoaging and pigmentation caused by UVA. Bis-ethylhexyloxyphenol methoxyphenyl triazine has both UVB and UVA protection capabilities, especially excellent absorption of UVB, which can enhance the composition's protection against medium-wave ultraviolet rays, while improving the stability of the sunscreen system and reducing the degradation of sunscreen agents under light.

[0018] Hydrogenated lecithin, as the main emulsifier, has excellent emulsifying and dispersing abilities, enabling the oil phase components (sunscreen agents, emollients, etc.) to mix evenly with the aqueous phase components (humectants, deionized water, etc.) to form a stable emulsion system, avoiding stratification and sedimentation. It also has certain moisturizing and repairing effects, enhancing the product's gentleness. Phytosterols assist in emulsification, enhancing the stability of the emulsion system, while also regulating the skin barrier function, reducing external irritation, improving the product's gentleness, and minimizing potential skin discomfort caused by sunscreens. Squalene assists in emulsification and also has moisturizing and soothing effects, relieving dry skin, enhancing skin tolerance to the composition, and further improving the product's gentleness.

[0019] Isonononyl isononanoate has a light texture and is easily absorbed by the skin. It can form a thin protective film on the skin surface, reduce skin moisture loss, and improve the smoothness of the product application, avoiding the greasy feeling common in sunscreen products. Shea butter is rich in unsaturated fatty acids, which have significant moisturizing and hydrating effects. It can repair the skin barrier, relieve dry and rough skin, and enhance the gentleness of products, making it suitable for sensitive skin. The main function of polyhydroxystearic acid is to stabilize the emulsion system, prevent emulsion separation and demulsification, and at the same time improve the dispersion stability of sunscreen agents in the emulsion, reduce sunscreen agent crystallization and precipitation, and ensure uniform sun protection effect. Glycerin, as a small-molecule moisturizer, can quickly penetrate into the stratum corneum of the skin, replenish skin moisture, lock in moisture, reduce skin dryness, improve the moisturizing performance of products, and enhance skin comfort; Butylene glycol has both moisturizing and solvent effects, which can help dissolve other water-soluble components, while replenishing skin moisture, enhancing the skin barrier function, and reducing external irritation. Preservatives are used to inhibit the growth and reproduction of microorganisms such as bacteria and fungi in the composition, extend the shelf life of the product, prevent the product from deteriorating and spoiling, and ensure that the product will not cause skin infection due to microbial contamination during use, thus ensuring the safety of product use; among them, hexanediol and ethylhexylglycerin also have a moisturizing auxiliary effect, further improving the gentleness of the product.

[0020] Photolyase primarily functions to repair skin, restoring skin DNA damage caused by UV radiation, reducing post-sun redness and stinging, while also enhancing the skin's own UV resistance and helping to improve the longevity of sun protection effects. Complex collagen (type I, type III, and type II collagen blended in a specific ratio): Type I collagen mainly maintains skin elasticity, type III collagen assists in repairing the skin barrier, and type II collagen enhances skin tolerance. The three work synergistically to repair the skin barrier, replenish skin nutrition, alleviate the slight irritation that sunscreens may cause, and improve the skin's resistance to ultraviolet rays. In addition, the moisturizing properties of collagen can further enhance the skin comfort of the product.

[0021] Ethylhexyl triazine ketone, ethylamino hydroxybenzoyl hexyl benzoate, and bis-ethylhexyloxyphenol methoxyphenyl triazine work synergistically to form a broad-spectrum sunscreen system. Ethylhexyl triazine ketone lays the foundation for broad-spectrum protection, ethylamino hydroxybenzoyl hexyl benzoate enhances UVA protection, and bis-ethylhexyloxyphenol methoxyphenyl triazine enhances UVB protection. The three work together to cover the entire UVB and UVA spectrum, significantly improving the sunscreen effect (SPF and PFA values ​​are significantly improved), and solving the problems of narrow protection range and insufficient protection intensity of single sunscreen agents. Synergistic effect of stabilizer and sunscreen system: Polyhydroxystearic acid can stabilize the sunscreen system, reduce the degradation of sunscreen under light, prolong the duration of sun protection effect, and prevent sunscreen crystallization and precipitation, ensuring uniform sun protection effect. It works synergistically with sunscreen components to achieve a highly efficient and long-lasting sun protection effect, which is the core reason why the 8-hour sun protection retention rate in the example is as high as 89.5%-93.1%.

[0022] Hydrogenated lecithin, phytosterols, and squalene are compounded in a specific ratio to form a stable emulsion system that can uniformly mix oil phase components (sunscreen agents, emollients) and water phase components (moisturizers, deionized water), avoiding stratification and emulsion breaking, and ensuring that the composition has a uniform and stable texture.

[0023] Synergistic effect of emulsifiers and stabilizers: Emulsifiers ensure uniform dispersion of all components, while stabilizers further enhance the stability of the emulsion system and prevent the precipitation of components such as sunscreens and emollients. The two work together to extend the storage and usage stability of the product. Emulsifiers, stabilizers, and deionized water work synergistically: Deionized water provides a dispersion carrier for each component, while emulsifiers and stabilizers ensure that each component is uniformly dispersed and stably present in water. The three work together to build a stable and uniform emulsion system, providing a foundation for the subsequent functions of sun protection, moisturizing, and repair.

[0024] Synergistic effect of emulsifiers and emollients: Both have the effect of soothing and repairing the skin barrier, which can reduce the skin irritation that may be caused by sunscreens and preservatives, and improve the gentleness of the product; The synergistic effect of moisturizers and emollients: Moisturizers replenish skin moisture, while emollients lock in moisture and hydrate the skin. Together, they improve dry skin, enhance skin tolerance to the composition, and further improve the product's gentleness and comfort. Preservatives work synergistically with other components: Preservatives inhibit microbial growth and ensure product safety. At the same time, mild preservatives (such as ethylhexylglycerin) are selected and work synergistically with emulsifiers and moisturizers to achieve the preservative effect while avoiding skin irritation, ensuring that all examples and comparative examples meet the level 0 non-irritation standard.

[0025] Photolyzed enzyme plus a specific ratio of compound collagen synergistically: The two are compounded in a mass ratio of 1:1-1.5. Photolyzed enzyme repairs skin DNA damage caused by ultraviolet rays, while compound collagen repairs the skin barrier and replenishes skin nutrition. The two work together to strengthen the skin's repair function, achieving the dual effects of sun protection and repair, solving the pain point of traditional sunscreen products that can only protect against the sun but cannot repair. Synergistic effect of repair and enhancement components with sunscreen system: The repair and enhancement components not only play a repairing role, but also have a synergistic effect with the sunscreen system with ethylhexyl triazone as the core, which significantly improves the sun protection effect (SPF, PFA value) and sun protection durability (8-hour sun protection retention rate). By comparing Example 1 and Comparative Example 1 (without repair and enhancement components), it can be seen that after adding this innovative component, SPF increased by 27.9 parts, PFA increased by 50.4 parts, and 8-hour sun protection retention rate increased by 17.4 parts, which fully demonstrates the synergistic effect of the two. Repairing and enhancing components work synergistically with other components: In synergy with emulsifiers, moisturizers, and emollients, they further enhance the product's gentleness and repairing effect, while also strengthening the skin's resistance to ultraviolet rays, forming a closed loop of protection-repair-stabilization.

[0026] Compared with the prior art, the present invention has the following beneficial effects: 1) With ethylhexyl triazine as the core sunscreen ingredient, combined with diethylamino hydroxybenzoyl hexyl benzoate and bis-ethylhexyloxyphenol methoxyphenyl triazine, the three work synergistically to fully cover the entire UVB and UVA spectrum, effectively compensating for the narrow protection range of a single sunscreen agent; at the same time, through the synergistic effect of each sunscreen ingredient, the sun protection strength of the composition is significantly improved (SPF value can reach 38.6-65.8, PFA value can reach 12.8-21.2), meeting the needs of daily and long-term outdoor sun protection.

[0027] 2) By adding the stabilizer polyhydroxystearic acid, the degradation of sunscreen agents under light can be effectively inhibited, and the duration of sun protection effect can be extended. According to the test, the sun protection index retention rate of the composition of the present invention is still as high as 89.5%-93.1% after 8 hours of simulated outdoor light exposure. At the same time, the stabilizer and emulsifier work together to effectively improve the stability of the emulsion system, avoid the product from layering, precipitation and other phenomena, and extend the shelf life of the product.

[0028] 3) By adding a repair-enhancing component composed of photolyase and complex collagen, photolyase can repair skin DNA damage caused by ultraviolet rays, while complex collagen can repair the skin barrier and replenish skin nutrition. The two work together to achieve the dual effects of sun protection and repair, solving the pain point of traditional sunscreen products that can only protect against the sun but cannot repair. At the same time, the precise ratio of emulsifiers, emollients and moisturizers further improves the gentleness of the product, making it suitable for all skin types, including sensitive skin. Detailed Implementation

[0029] The present invention will be further described in detail below with reference to specific embodiments.

[0030] The sun protection efficacy tests for all embodiments and comparative examples of this invention were conducted using the following standardized methods to ensure the comparability of the test results: 1. Sun Protection Factor (SPF) Test: In accordance with the method for determining sun protection factor in GB / T 23127-2008 "Technical Specifications for Cosmetic Safety", the UV-2600 ultraviolet-visible spectrophotometer was used to test the ultraviolet absorption capacity of the sample on the skin simulant and calculate the SPF value. The higher the SPF value, the stronger the product's protection against medium-wave ultraviolet (UVB) radiation.

[0031] 2. Protection Factor (PFA) Test: According to GB / T 32091-2015 "Determination Method of Protection Factor (PFA) of Cosmetics", the PFA value is calculated by measuring the sample's ability to protect against long-wave ultraviolet (UVA). The higher the PFA value, the better the product's protection against UVA.

[0032] 3.8h Sun Protection Retention Rate (SPF) Test: The sample was applied to a skin simulant to simulate outdoor natural light conditions (light intensity 10000 lux, temperature 25±2℃, humidity 50±5 ppm). After continuous exposure to light for 8 hours, the SPF value was measured again. The ratio of the SPF value after 8 hours to the initial SPF value was calculated, which is the sun protection retention rate. The higher the retention rate, the better the product's sun protection durability.

[0033] 4. Skin irritation test: In accordance with GB / T 16886.5-2017 "Biological evaluation of medical devices - Part 5: In vitro cytotoxicity test", the in vitro skin irritation test method was used to score the irritation of the samples. Grade 0 is no irritation (no redness, swelling, or stinging), Grade 1 is slight irritation, and Grade 2 and above are significant irritation. All embodiments of this invention must meet the Grade 0 no irritation standard.

[0050] The preparation method is the same as that in Example 1, except that the water bath heating accuracy is ±2℃, the oil phase addition rate is 7mL / min, and the repair component is added after cooling to 42℃.

[0051] Example 5

[0052] The composition comprises, by weight percentage, the following components: 6.0 parts ethylhexyl triazine, 3.08 parts diethylamino hydroxybenzoyl hexyl benzoate, 4.92 parts bis-ethylhexyloxyphenol methoxyphenyl triazine, 2.0 parts hydrogenated lecithin, 1.33 parts phytosterol, 0.67 parts squalene, 4.0 parts isononyl isononanoate, 2.0 parts shea butter, 0.8 parts stabilizer octocrylene, 7.2 parts glycerin, 4.8 parts butylene glycol, 0.35 parts preservative ethylhexylglycerin, 1.5 parts repair and synergistic component (0.65 parts photolyase, 0.85 parts collagen, the collagen being composed of type I collagen, type III collagen and type II collagen in a mass ratio of 13:2:85), and deionized water to a total of 100 parts.

[0053] The same preparation method as in Example 3 (water bath heating accuracy ±2℃, oil phase addition rate 9mL / min, cooling to 43℃ before adding the repair component).

[0054] Comparative Examples 1-5

[0055] Composition formulation: The formulation is exactly the same as that in Examples 1-5, except that the repair and synergistic components (photolysin and collagen) are removed, and deionized water is added to make up to 100 parts.

[0056] Preparation method: The preparation method is exactly the same as that in Examples 1-5, except that the steps of adding the repair and synergistic components and stirring are omitted.

[0057] Comparative Example 6

[0058] Composition formulation: The formulation is exactly the same as that in Example 1, except that the proportion of the repair and synergistic components is adjusted. The mass ratio of photolyase to collagen is 1:3 (0.25 parts photolyase and 0.75 parts collagen), and the contents of the other components remain unchanged.

[0059] Preparation method: The preparation method is exactly the same as that in Example 1.

[0060] Sunscreen efficacy test data: SPF 50.3; PFA 14.7; after 8 hours of simulated outdoor sunlight exposure, SPF retention rate was 85.2%; skin irritation rating was 0, indicating no irritation.

[0061] The test results show that: no repair and enhancement components were added to Comparative Examples 1-5. The SPF and PFA of Examples 1-5 were significantly higher than those of Comparative Example 1: the SPF value of Example 1 was 12.7 higher than that of Comparative Example 1, an increase of 27.91%; the SPF value of Example 3 was the highest, higher than that of Comparative Example 1, an increase of 44.62%.

[0062] The PFA value of Example 1 was 6.2 higher than that of Comparative Example 1, representing an improvement of 50.41%; the PFA value of Example 3 was the highest, higher than that of Comparative Example 1, representing an improvement of 72.36%. This difference indicates that the repair and synergistic components and the ethylhexyl triazone complex sunscreen system have a synergistic effect, significantly improving the core protection capabilities against UVB (medium-wave ultraviolet radiation) and UVA (long-wave ultraviolet radiation).

[0063] In Comparative Example 6, the ratio of the repairing and synergistic components (photolysin:collagen = 1:3) exceeded the 1:1-1.5 range specified in this invention. While its SPF and PFA values ​​were higher than Comparative Example 1 (without the repairing component), they were still significantly lower than other examples. The SPF value of Comparative Example 6 was lower than that of Examples 1, 3, and 5, and only slightly higher than that of Examples 2 and 4. The PFA value of Comparative Example 6 was lower than all examples. This indicates that the ratio of the repairing and synergistic components is crucial for achieving synergy with the sunscreen system. Only by strictly limiting it to the 1:1-1.5 range can the synergistic effect of sunscreen be maximized; deviations from this ratio will significantly weaken the synergistic effect.

[0064] The above embodiments are not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present invention are also within the protection scope of the present invention.
