Abstract
Description
Technical Field
[0001] This invention relates to the field of skincare products, and in particular to a sunscreen composition and its preparation method. Background Technology
[0002] Sunscreen skincare products are used to protect the skin and reduce the damage caused by ultraviolet (UV) rays. Existing sunscreen skincare products mainly achieve their sun protection effect by adding chemical sunscreens. Chemical sunscreens have the function of absorbing UVA and UVB rays, making it difficult for UV rays to directly act on the skin after being absorbed by the chemical sunscreens. This reduces the effect of UV rays in promoting melanin synthesis in the skin, and also reduces the damage of UV rays to the skin.
[0003] Sunscreen products need to completely cover the skin to achieve a comprehensive sun protection effect. However, after using sunscreen, the skin's ability to breathe is restricted due to the barrier effect of the sunscreen, which can irritate the skin, increase oil production, and, with long-term use, induce skin allergies and easily lead to acne. Therefore, although existing sunscreen products have good skin care effects, they are not skin-friendly enough and can easily cause new skin problems, failing to meet consumer needs and thus there is room for improvement. Summary of the Invention
[0004] In order to provide a sunscreen skincare product with good sun protection function while alleviating the problems of oily skin, allergies, and acne caused by long-term use, this application provides a sunscreen composition and its preparation method.
[0005] In a first aspect, this application provides a sunscreen composition, which adopts the following technical solution: A sunscreen composition comprising the following components in parts by weight: Water 76.9-85.7 parts; Sunscreen agent 10.4-16.6 parts; 2-4 parts emulsifier; 1.5-1.9 parts of the compound extract; Preservative: 0.4-0.6 parts; The compound extract is a combination of sturgeon caviar extract, Japanese cedar bud extract, Arabidopsis thaliana extract, and Scutellaria barbata extract.
[0006] By adopting the above technical solution, a compound extract composed of sturgeon caviar extract, Japanese cedar bud extract, Arabidopsis thaliana extract, and Scutellaria barbata extract is added to the sunscreen composition. Through the synergistic effect of the active ingredients of each extract, a significant oil-controlling effect can be achieved, reducing skin oil production and thus reducing pore blockage caused by excessive sebum secretion, thereby reducing the risk of acne. Furthermore, the synergistic effect of each composition can exert good antibacterial properties, inhibiting the reproduction of Propionibacterium acnes, further reducing the risk of acne. At the same time, it can also exert a good soothing effect, reducing skin allergies. Long-term use of the sunscreen composition is unlikely to cause skin discomfort, allowing the skin to maintain a healthier state and better meeting consumer needs.
[0007] Preferably, the mass ratio of sturgeon caviar extract, Japanese cedar bud extract, Arabidopsis thaliana extract, and Scutellaria barbata extract in the compound extract is 0.35-0.45: 0.55-0.65: 0.15-0.25: 0.45-0.55.
[0008] By adopting the above technical solution and specifically selecting the mass ratio of sturgeon caviar extract, Japanese cedar bud extract, Arabidopsis thaliana extract, and Scutellaria barbata extract, the active ingredients of each extract are better combined in a specific ratio, resulting in better synergistic effects and enhanced oil control, antibacterial, and soothing effects.
[0009] Preferably, the sunscreen agent is a compound of butyl methoxydibenzoylmethane, ethylhexyl methoxycinnamate, diethylaminohydroxybenzoylhexyl benzoate, and bisabolol.
[0010] By adopting the above technical solution and specifically selecting the combination of butyl methoxydibenzoylmethane, ethylhexyl methoxycinnamate, diethylaminohydroxybenzoylhexyl benzoate, and bisabolol, the absorption of UVA and UVB is better, and the sun protection effect is better.
[0011] Preferably, in the sunscreen agent, the mass ratio of butyl methoxydibenzoylmethane, ethylhexyl methoxycinnamate, and diethylamino hydroxybenzoyl hexyl benzoate is 3-5:2-4:5-7:0.4-0.6.
[0012] By adopting the above technical solution and specifically selecting the mass ratio of butyl methoxydibenzoylmethane, ethylhexyl methoxycinnamate, and diethylaminohydroxybenzoylhexyl benzoate, the sun protection effect is better.
[0013] Preferably, the emulsifier is a combination of glyceryl stearate and cetyl phosphate.
[0014] By adopting the above technical solution and specifically selecting glyceryl stearate and cetyl phosphate, the emulsification effect is better, the components are more uniformly dispersed in water, and the product quality is stable.
[0015] Preferably, the mass ratio of glyceryl stearate to cetyl phosphate in the emulsifier is 1-2:1-2.
[0016] By adopting the above technical solution and specifically selecting the mass ratio of glyceryl stearate and cetyl phosphate, the emulsification stability is higher and the product quality is better.
[0017] Preferably, the preservative is 1,2-hexanediol.
[0018] By adopting the above technical solution and specifically selecting 1,2-hexanediol, the preservative effect is better, while the irritation is lower and it is more skin-friendly.
[0019] Secondly, this application provides a method for preparing a sunscreen composition, using the following technical solution: A method for preparing the above-mentioned sunscreen composition includes the following steps: Step 1), mix water, sunscreen, and emulsifier, heat to 80-85℃, homogenize for 3-5 minutes, stir for 10-15 minutes to obtain a premix; Step 2), cool the premix to 40°C or below, then add the compound extract and preservative to the premix, stir well to obtain the sunscreen composition.
[0020] By adopting the above technical solution, the prepared sunscreen composition has good absorption effect in both UVA and UVB regions, and has a better sun protection effect. At the same time, it also has good soothing, oil control and antibacterial effects. Long-term use of the sunscreen composition is not likely to cause skin discomfort, which is conducive to maintaining skin health and well meets the needs of consumers.
[0021] In summary, this application has the following beneficial effects: 1. Because this application incorporates a compound extract composed of sturgeon caviar extract, Japanese cedar bud extract, Arabidopsis thaliana extract, and Scutellaria barbata extract into the sunscreen composition, the active ingredients of each extract work synergistically to exert a significant oil-controlling effect, reducing skin oil production and thus reducing pore blockage caused by excessive sebum secretion, thereby reducing the risk of acne. Furthermore, the synergistic effect of each composition provides good antibacterial properties, inhibiting the reproduction of Propionibacterium acnes, further reducing the risk of acne. At the same time, it also provides good soothing effects, reducing skin allergies. Long-term use of the sunscreen composition is unlikely to cause skin discomfort, allowing the skin to maintain a healthier state and better meeting consumer needs.
[0022] 2. In this application, the preferred method is to select the specific mass ratio of sturgeon caviar extract, Japanese cedar bud extract, Arabidopsis thaliana extract, and Scutellaria barbata extract so that the active ingredients of each extract can be better combined in a specific ratio, resulting in better synergistic effects and better oil control, antibacterial and soothing effects.
[0023] 3. In this application, the preferred combination of butyl methoxydibenzoylmethane, ethylhexyl methoxycinnamate, diethylamino hydroxybenzoyl hexyl benzoate, and bisabolol has a better effect on absorbing UVA and UVB and provides better sun protection. Detailed Implementation

[0091] Experiment 1 The antibacterial performance of the sunscreen compositions in each example and comparative example was tested according to the test methods in section 7.3 of QB / T 2738-2023 "Evaluation Method for Antibacterial and Bacteriostatic Effects of Daily Chemical Products".
[0092] Antibacterial rate (%) = (A - B) / A * 100 In the formula: A—The average colony count of the control sample; B—The average number of colonies in the test sample.
[0093] Experimental bacterial strain: Propionibacterium acnes, ATCC11827.
[0094] The inhibition time was 5 minutes.
[0095] Preparation of the test sample: 2g of acne-removing composition and 98g of deionized water were mixed evenly to obtain the test sample.
[0096] Experiment 2 The hyaluronidase inhibition rate (%) of the sunscreen compositions in each example and comparative example was tested according to T / JSRH 003-2023 "Test of Anti-allergic Activity of Cosmetic Raw Materials - Hyaluronidase Inhibition Method".
[0097] Experiment 3 Several volunteers were recruited and divided into groups of ten. Each group used the sunscreen compositions from the various examples and comparative examples. Before use, the volunteers cleaned their faces with water and disposable face towels. Then, 5ml of the test sample was applied evenly to the face. After 4 hours of free movement, the oil content on the forehead was measured using a multi-functional skin analyzer (MPA580) with an SM815 probe. This was recorded as the oil content on the skin after 4 hours of sunscreen use. The volunteers then removed the sunscreen composition with makeup remover oil, cleaned their faces again with water and disposable face towels, and moved freely for another 4 hours. The oil content on the forehead was measured again using a multi-functional skin analyzer (MPA580) with an SM815 probe. This was recorded as the oil content on the skin after 4 hours of not using sunscreen. The increase in skin oil content after using the sunscreen composition was calculated.
[0098] Increase in skin oil content after using sunscreen = Skin oil content after 4 hours with sunscreen - Skin oil content after 4 hours without sunscreen.
[0099] The experimental data for Experiments 1-3 are detailed in Table 1.
[0100] Table 1
[0101] According to the data in Table 1, all examples and comparative examples have good antibacterial effects. The hyaluronidase inhibition rate of each example is significantly higher than that of the comparative examples. The increase in skin oil after using the sunscreen composition in each example is significantly lower than that in the comparative examples. It can be seen that the combination of sturgeon caviar extract, Japanese cedar bud extract, Arabidopsis thaliana extract and Scutellaria barbata extract can play a good synergistic role, so that the sunscreen composition can have significant oil control, antibacterial and soothing effects, effectively alleviate the skin damage caused by long-term use of the sunscreen composition, make the skin healthier, and better meet the needs of consumers.
[0102] Comparative Examples 1-5 were replaced with other extracts that have antibacterial, soothing, and oil-controlling effects, but their soothing and oil-controlling effects were not as good as those of the examples. This proves that after Comparative Examples 1-5 destroyed the compound system of caviar extract, Japanese cedar bud extract, Arabidopsis thaliana extract, and Scutellaria barbata extract, the synergistic effect was not good and it was difficult to significantly improve the oil-controlling and soothing effects.
[0103] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
