Description

Technical Field

[0001] This invention belongs to the field of cosmetic technology and provides an additive, sunscreen composition and application that can improve the sun protection factor. Background Technology

[0002] Sunscreen protects against photoaging caused by ultraviolet (UV) radiation. UVA (long-wave ultraviolet) rays cause skin to lose elasticity, leading to wrinkles and sagging, and accelerate the photoaging process. UVB (medium-wave ultraviolet) rays, on the other hand, are the main cause of sunburn and erythema, causing skin darkening, peeling, and in severe cases, inflammation. Sunscreen products on the market are generally categorized into physical and chemical sunscreens based on their ingredients.

[0003] Physical sunscreens reflect, scatter, and refract ultraviolet rays through titanium dioxide and zinc oxide particles. Their main components are titanium dioxide (TiO2) and zinc oxide (ZnO). Compared to chemical sunscreens, they are gentler, more stable, and provide long-lasting protection. my country's "Cosmetic Safety Technical Specifications" (IECIC 2015) stipulates that the maximum addition amount of both titanium dioxide and zinc oxide is 25%. However, adding large amounts of titanium dioxide can make sunscreens appear white and heavy, difficult to spread, and may also cause whitening, breakouts, and other problems, resulting in a poor consumer experience. Furthermore, titanium dioxide is often combined with zinc oxide to enhance protection or paired with chemical sunscreen agents (such as avobenzone) to cover the entire UV spectrum.

[0004] Chinese invention patent application CN107468585A discloses a composition for improving dull and yellowish skin tone, its preparation, and its application in cosmetics. The composition includes: Artemisia argyi extract, Laminaria japonica extract, sodium hyaluronate, glucosyl hesperidin, nano-titanium dioxide, a moisturizer, an emulsifier, a thickener, a preservative, a surfactant, a pH adjuster, and water. This composition for improving dull and yellowish skin tone can eliminate skin dullness, increase radiance, and restore a clear, flawless, and translucent complexion. It is a multi-functional skincare product that perfectly combines improving dull and yellowish skin tone, moisturizing, and anti-wrinkle effects, with good synergistic effects among its components.

[0005] Chemical sunscreens work by absorbing ultraviolet energy through chemical components and releasing it as heat. Common ingredients include ethylhexyl methoxycinnamate, bis-ethylhexyloxyphenol methoxyphenyl triazine, ethylhexyl salicylate, avobenzone, octocrylene, and homosalate. They have a light texture, a refreshing feel, and offer broader sun protection. However, some ingredients can be irritating and may not be suitable for sensitive skin; they also usually require a combination of multiple ingredients.

[0006] For example, Chinese invention patent CN110251406B discloses a sunscreen spray containing the following components: titanium dioxide, octyl methoxycinnamate, methylene bis-benzotriazolyl tetramethylbutylphenol, and butyl methoxydibenzoylmethane. This sunscreen spray uses a combination of physical sunscreens (titanium dioxide) and chemical sunscreens (octyl methoxycinnamate, methylene bis-benzotriazolyl tetramethylbutylphenol, and butyl methoxydibenzoylmethane), giving it both a good skin feel and good sun protection effect. However, titanium dioxide particles tend to aggregate in aqueous systems, forming uneven suspensions, which reduces the transdermal absorption rate of whitening ingredients.

[0007] Therefore, regardless of whether it is a physical or chemical sunscreen, the user experience (such as ensuring a light texture that does not leave a white cast or cause breakouts) and safety (non-irritating, suitable for all skin types such as sensitive skin) are two aspects that cannot be ignored. For example, adding specific substances to reduce the amount of sunscreen ingredients used may be the key to solving the above problems. Summary of the Invention

[0023] Thirdly, the present invention also provides a sunscreen composition comprising a sunscreen agent and the above-mentioned additives.

[0024] Furthermore, the sunscreen agent includes physical sunscreen agents and / or chemical sunscreen agents; In some preferred embodiments of the present invention, the physical sunscreen agent is titanium dioxide and / or zinc oxide.

[0025] As some preferred embodiments of the present invention, the chemical sunscreen agent is one or more of the following: ethylhexyl methoxycinnamate, bis-ethylhexyloxyphenol methoxyphenyl triazine, diethylaminohydroxybenzoylhexyl benzoate, butyl methoxydibenzoylmethane, isoamyl β-methoxycinnamate, ethylhexyl salicylate, octocrylene, humosasulfate, phenylbenzimidazole sulfonic acid, disodium phenyldibenzimidazole tetrasulfonate, terephthalimide dicamphor sulfonic acid, cresoltrazolium trisiloxane, ethylhexyl triazine ketone, diethylhexylbutamidotriazine ketone, and methylene bis-benzotriazolyl tetramethylbutylphenol.

[0028] Furthermore, the sunscreen product is in the form of any one of cream, lotion, gel, and aerosol spray.

[0029] Compared with the prior art, the present invention has the following beneficial effects: The glucosyl hesperidin selected in this invention is a potent antioxidant that can neutralize free radicals generated by ultraviolet radiation, reducing the effectiveness of sunscreens due to photo-oxidation. Furthermore, it can indirectly enhance the protective effect by improving skin microcirculation and moisturizing ability, thereby increasing the even distribution and durability of sunscreen ingredients. Forsythia suspensa extract contains hypericin and flavonoids, which neutralize free radicals generated by ultraviolet radiation, reducing the photo-oxidative loss of sunscreens. It also inhibits the release of pro-inflammatory factors, alleviating post-sun exposure redness and sensitivity, and enhancing skin barrier stability. Additionally, it has an inhibitory effect on common acne-causing bacteria such as Staphylococcus aureus, reducing the risk of breakouts caused by sunscreen products. The synergistic effect of these two ingredients can significantly enhance the sun protection effect of various physical and chemical sunscreens, exhibiting a broad-spectrum ability to improve sun protection, ensuring the same sun protection effect with a smaller amount of sunscreen.

[0030] In addition, Spirulina MAXIMA extract is rich in easily absorbed plant protein, essential amino acids and vitamin B12, which can not only provide nutritional enhancement but also regulate skin immunity. Furthermore, the phycocyanin and β-carotene in Spirulina MAXIMA extract can scavenge free radicals. When combined with glucosyl hesperidin and Forsythia suspensa extract, it can further enhance the sun protection effect of sunscreens. Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Basic Implementation This basic embodiment provides different additive compositions, which are directly mixed evenly according to the amounts in Table 1 to obtain each additive.

First, stir at 350 rpm for 5 minutes to initially mix the two phases, and then emulsify at 800 rpm for 15 minutes. (4) Homogeneous The emulsion obtained in step (3) was transferred to a high shear homogenizer and homogenized for 3 minutes at a temperature of 70-75℃ and a speed of 10000-12000 rpm. (5) After the system cools down to room temperature, it is sterilized and filled to obtain the corresponding sunscreen.

[0038] Among them, sunscreen B0 contains no additives, while the additives in sunscreens B1 to B13 are additives 1 to 13 respectively.

[0039] Table 3

[0040] Example 3 The sunscreen product (sunscreen cream) was prepared according to the formula in Table 4. The preparation process is as follows: (1) Preparation of oil extraction phase: Add dibutyl adipate, octyl polydimethylsiloxane, cetearyl alcohol, polydimethylsiloxane, dioctyl carbonate, and MONTANOV 68 MB to the oil phase pot, stir and heat (80-85℃) until completely melted; then add bis-ethylhexyloxyphenol methoxyphenyl triazine, ethylhexyl methoxycinnamate, titanium dioxide, ethylhexyl triazine ketone, and diethylamino hydroxybenzoyl hexyl benzoate in sequence, and stir until homogeneous; (2) Preparation of aqueous phase Add deionized water to the aqueous phase pot and heat it to 80-85℃.

First, stir at 350 rpm for 5 minutes to initially mix the two phases, and then emulsify at 800 rpm for 15 minutes. (4) Homogeneous The emulsion obtained in step (3) was transferred to a high shear homogenizer and homogenized for 3 minutes at a temperature of 70-75℃ and a speed of 10000-12000 rpm. (5) After the system cools down to room temperature, it is sterilized and filled to obtain the corresponding sunscreen.

[0041] Among them, sunscreen C0 contains no additives, while the additives in sunscreens C1 to C13 are additives 1 to 13 respectively.

[0042] Table 4

[0043] Test Example 1: In vitro (in-vitro) test of SPF and PA values ​​of sunscreen products containing the additives of this invention. The sunscreens prepared in Examples 1-3 above were used at a concentration of 2 ± 0.05 mg / cm³. 2The amount of [agent] was uniformly coated onto a PMMA board and irradiated with a xenon arc lamp using a solar simulator (wavelength range: 290-400nm ultraviolet light, with radiation <290nm less than 1% and >400nm less than 5%). The SPF and PA values ​​were scanned and tested using a UV2000S ultraviolet transmittance analyzer. Ten points were selected for testing on each board, and the average value was taken. The results are shown in Table 5.

[0044] Table 5

[0045] Taking the data results of each sunscreen in Example 1 as an example, comparing the sunscreens A1-A7 containing additives with the sunscreen A0 without additives, except for sunscreens A1 and A7, the SPF and PA values ​​of the other sunscreens are higher than those of A0. It can be seen that the combination of glucosyl hesperidin and forsythia extract can significantly improve the sun protection effect of the product.

[0046] A8-A10 are based on A4 and contain different amounts of Spirulina macrophylla extract. With a fixed total amount of additives, the addition of Spirulina macrophylla extract further enhances the sun protection effect of the sunscreen. However, when the additives are only Spirulina macrophylla extract or Spirulina macrophylla extract and one of glucosyl hesperidin or Forsythia suspensa extract, although the total amount of additives remains the same, there is no effect of increasing the sun protection factor.

[0047] It is evident that only combinations of specific ingredients, such as glucosyl hesperidin and forsythia extract, or a combination of spirulina extract, glucosyl hesperidin, and forsythia extract, can enhance the sun protection effect of sunscreens.

[0048] Furthermore, Examples 1-3, which contain different sunscreen agents, all showed the same results as Example 1, indicating that the additives of the present invention have broad applicability. For different types of sunscreens, the sun protection effect is improved after using the additives of the present invention, and the effect of improving the sun protection index of the sunscreen is not affected by other raw and auxiliary materials in the formula.

[0049] Test Example 2: Human Efficacy Evaluation Test of Sunscreen Products Containing the Additives of the Present Invention The Cosmetic Safety Technical Specifications (2015 Edition) measures the SPF and PA values ​​of the sunscreen prepared by this invention to evaluate its sun protection effect.

[0050] I. Materials and Methods 1. Tested substances: Sunscreens A0, A4, and A8; 2. Control: Prepare a cream without sunscreen ingredients as a control according to the formula in Table 2 and the preparation method in Example 1 (only omitting the sunscreen component, and making up the missing amount with deionized water); 3. Subjects: Ten subjects who met the subject voluntary inclusion criteria (aged 27-45 years, mean age 35±1) were divided into two groups, one group for testing SPF value and the other group for testing PFA value. 4. Light source: Daylight-simulated xenon arc lamp, all performance indicators meet the requirements of the testing specifications; 5. Test methods: (1) MED: The subject was positioned in a forward-leaning position, and their back was irradiated. The minimum erythema dose (MED) of the subject's skin to ultraviolet radiation was predicted 24 hours prior to the test, and the ultraviolet radiation dose was adjusted based on the prediction results for testing the analyte. First, four points at least 30cm apart were selected on the subject's back. 2 In normal skin areas, at 2±0.05 mg / cm² 2 The dosage of the test substance A0, A4, A8 and the control substance was evenly applied to the four areas of each subject. Then, the irradiation dose was selected according to the standard requirements. The experimental results were observed after 24 hours, and the MED values ​​were recorded.

[0051] (1) MPPD: The subject was positioned in a forward-leaning position, and their back was irradiated. The minimum melanization potential (MPPD) of the subject's skin to ultraviolet radiation was predicted 24 hours prior to the test, and the ultraviolet radiation dose was adjusted based on the prediction. This was used to test the analyte. Four points at least 30cm in length were first selected on the subject's back. 2 In normal skin areas, at 2±0.05 mg / cm² 2 The test substances A0, A4, A8 and the control were evenly applied to the four areas of each subject. Then, the irradiation dose was selected according to the standard requirements. The experimental results were observed after 3 hours, and the MPPD values ​​were recorded.

[0052] 6. Calculation methods for SPF and MPPD values: The SPF and PFA values ​​of the analyte or control for protecting a single subject are expressed by the following formula: SPF = MED value of protected skin / MED value of unprotected skin PFA = MPPD value of protected skin / MPPD value of unprotected skin Individual SPF and PFA values ​​must be accurate to one decimal place. The average SPF and PFA values ​​of all subjects protected by the test substance are calculated, which is the SPF and PFA value of the sample being tested. The results are shown in Table 6.

[0053] II. Test Results Table 6

[0054] The above results further verify that the additives of the present invention containing glucosyl hesperidin and forsythia extract, as well as those containing glucosyl hesperidin, forsythia extract and spirulina extract, can all improve the sun protection factor of sunscreens. At an addition amount of 1%, the sun protection effect of different products is significantly improved, achieving the effect of reducing the amount of sunscreen and increasing the efficiency, and has a wide range of applications in sunscreen products.

[0055] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, and is not intended to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
