Description

Technical Field

[0001] This application relates to the field of daily cosmetic technology, and in particular to a non-emulsified sunscreen composition and its preparation method. Background Technology

[0002] Existing water-in-oil high-SPF sunscreens on the market all suffer from drawbacks such as a sticky feel on the skin or water-oil separation. Physical sunscreens are often environmentally damaging and incompatible with physical and chemical systems. High-SPF sunscreens are mostly oil-soluble and require high-concentration emulsifiers for forced emulsification. However, during long-term storage or exposure to temperatures above 45°C or below -15°C, the large density difference between oil and water and insufficient strength of the emulsifier interfacial film can easily lead to oil droplets floating and oil separation, resulting in uneven distribution of sunscreen agents and fluctuations in actual protective efficacy. Summary of the Invention

[0003] This application develops a non-emulsified sunscreen composition and its preparation method. It uses a non-emulsified stabilizing thickening technology to overcome the problems of water-oil separation, environmental damage caused by physical sunscreens, and incompatibility of physicochemical systems in water-in-oil type high SPF sunscreen compositions.

[0004] In a first aspect of this application, a non-emulsified sunscreen composition and its preparation method are provided, comprising the following raw materials in weight percentages: 1-1.4% acrylic acid / stearyl alcohol polyether-20 methacrylate copolymer, 0.064-0.096% microcrystalline cellulose, 0.01-0.03% cellulose gum, 0.04-0.06% sphingosine monocytogenes fermentation product extract, 0.01-0.03% Panax notoginseng root extract, 0.45-0.55% dimethylsilanol hyaluronic acid ester, 0.1-0.3% silica, 0.2-0.4% polymethylsiloxane, 20-30% sunscreen agent, 10-20% emollient, 5.6-6.5% additives, and the balance being water.

[0005] By employing the above technical solution, this application provides a non-emulsified sunscreen composition with good stability and high SPF protection. This is likely because, on the one hand, cellulose gum forms a basic viscosity through dynamic hydrogen bonds between hydroxyl groups and carboxylic acid groups in the acrylic copolymer, while microcrystalline cellulose, as a rigid fiber, forms a composite network through surface hydrogen bonding. The synergistic effect of these three components improves the stability of the non-emulsified sunscreen composition. On the other hand, the free radical scavenging ability of Panax notoginseng root extract protects the integrity of sunscreen molecules, while Sphingosporium sphingosine monophosphate extract assists in antioxidation and can form an adsorption layer on the surface of oil droplets, stabilizing the structure. Thus, while ensuring the stability of the non-emulsified sunscreen composition, a high SPF protection effect can also be maintained.

[0006] Optionally, the mass ratio of the Sphingomonas fermentation product extract to the Panax notoginseng root extract is (1.33-6):1.

[0007] By adopting the above technical solution and adjusting the amounts of Sphingomonas fermentation product extract and Panax notoginseng root extract according to the above mass ratio, when the mass ratio of Sphingomonas fermentation product extract and Panax notoginseng root extract is (1.33-6):1, the stability of the non-emulsified sunscreen composition can be well guaranteed, and it has a high sun protection effect.

[0008] Optionally, the preparation method of the Panax notoginseng root extract includes the following steps: The roots of Panax notoginseng are crushed and added to water at a ratio of 1:(8-15) (g / mL). The mixture is then ultrasonically extracted at 55-65℃ for 50-70 minutes. The mixture is filtered, the filtrate is collected, concentrated, centrifuged, and the supernatant is collected. Ethanol is added, the mixture is stirred, allowed to stand, centrifuged again, the precipitate is collected, and the mixture is freeze-dried to obtain the Panax notoginseng root extract.

[0009] Optionally, the mass ratio of the acrylic acid / stearyl alcohol polyether-20 methacrylate copolymer, microcrystalline cellulose, and cellulose gum is (1.18-1.22):(0.064-0.096):(0.016-0.024).

[0010] By adopting the above technical solution and adjusting the amounts of acrylic acid / stearyl alcohol polyether-20 methacrylate copolymer, microcrystalline cellulose, and cellulose gum according to the above mass ratio, when the mass ratio of acrylic acid / stearyl alcohol polyether-20 methacrylate copolymer, microcrystalline cellulose, and cellulose gum is (1.18-1.22):(0.064-0.096):(0.016-0.024), the stability of the non-emulsified sunscreen composition can be guaranteed, and it has a high SPF sunscreen effect.

[0011] Optionally, the sunscreen agent includes 4-6% by weight of butyl methoxydibenzoylmethane, 6-10% by weight of octocrylene, 3-5% by weight of bis-ethylhexyloxyphenol methoxyphenyl triazine, 3-5% by weight of ethylhexyl salicylate, 0.5-1.5% by weight of polysiloxane-15, and 2-4% by weight of ethylhexyl triazine ketone.

[0012] Optionally, the emollient includes 6-10% by weight of dibutyl adipate, 1-3% by weight of diisopropyl adipate, 1-3% by weight of diisopropyl sebacate, and 2-4% by weight of isododecane.

[0013] Optionally, the auxiliary agent includes 0.05-0.2% by mass of EDTA-2Na, 3-8% by mass of 1,3-propanediol, 0.1-0.3% by mass of 1,2-hexanediol, 0.05-0.15% by mass of p-hydroxyacetophenone, 0.1-0.3% by mass of arginine, 0.2-0.4% by mass of phenoxyethanol, and 0.1-0.3% by mass of fragrance.

[0014] In a second aspect, this application provides a method for preparing a non-emulsified sunscreen composition as described in the first aspect, comprising the following steps: S1: Acrylic acid / stearyl alcohol polyether-20 methacrylate copolymer, microcrystalline cellulose, cellulose gum, Sphingomonas fermentation product extract, Panax notoginseng root extract, EDTA-2Na, 1,3-propanediol, 1,2-hexanediol, p-hydroxyacetophenone, and dimethylsilanol hyaluronic acid ester are added to water, heated to 75-85℃, and stirred to obtain phase A; S2: Dibutyl adipate, diisopropyl adipate, diisopropyl sebacate, isododecane, butyl methoxydibenzoylmethane, octocrylene, bis-ethylhexyloxyphenol methoxyphenyl triazine, ethylhexyl salicylate, polysiloxane-15, and ethylhexyl triazine ketone are stirred at 75-85℃ to obtain phase B; S3: Stir silica and polymethylsiloxane at 75-85°C to obtain phase C; add phase B obtained in step S2 and phase C obtained in step S3 to phase A obtained in step S1 at 75-85°C, and homogenize to obtain a mixed phase; S4: Add arginine to water and stir to obtain phase D; S5: Cool the mixed phase prepared in step S3, add the D phase prepared in step S4, then add phenoxyethanol and fragrance, stir, and obtain the non-emulsified sunscreen composition.

[0015] Optionally, in step S3, the homogenization rotation speed is 8000-12000 r / min, and the homogenization time is 4-6 min.

[0016] In a third aspect of this application, this application provides the use of the non-emulsified sunscreen composition described in the first aspect of this application in the preparation of sunscreen.

[0017] In summary, the present invention has at least one of the following beneficial technical effects: 1. This application provides a non-emulsified sunscreen composition with good stability and high SPF protection. Cellulose gum forms a basic viscosity through dynamic hydrogen bonds between hydroxyl groups and carboxylic acid groups in the acrylic copolymer. Microcrystalline cellulose, as a rigid fiber, forms a composite network through surface hydrogen bonding. The synergistic combination of these three components improves the stability of the non-emulsified sunscreen composition. Furthermore, the free radical scavenging ability of Panax notoginseng root extract protects the integrity of the sunscreen molecules, while Sphingosporium sphingosine monophosphate extract provides antioxidant protection and forms an adsorption layer on the surface of oil droplets, stabilizing the structure. Therefore, while ensuring the stability of the non-emulsified sunscreen composition, a high SPF protection effect can also be maintained.

[0038] The preparation method is the same as in Example 1.

[0040] The preparation method is the same as in Example 1.

[0041] Comparative Example 3 Comparative Example 3 provides a non-emulsified sunscreen composition that differs from Example 1 in that an equal mass of acrylic acid / stearyl alcohol polyether-20 methacrylate copolymer is replaced with polyquaternium-67.

[0042] The preparation method is the same as in Example 1.

[0044] The preparation method is the same as in Example 1.

[0045] Performance testing The non-emulsified sunscreen compositions prepared in Examples 1-5 and Comparative Examples 1-4 were left to stand for 144 hours at -20°C, room temperature, 40°C, 45°C and 50°C, respectively. The stratification of the non-emulsified sunscreen compositions prepared in Examples 1-5 and Comparative Examples 1-4 was observed to characterize the stability of the non-emulsified sunscreen compositions. The results are shown in Table 1.

[0046] Table 1

[0047] Based on Examples 1, 2-3, and Table 1, it can be seen that in Examples 2 and 3, under the acrylic acid / stearyl alcohol polyether-20 methacrylate copolymer system, by adjusting the mass ratio of acrylic acid / stearyl alcohol polyether-20 methacrylate copolymer, microcrystalline cellulose, and cellulose gum within a suitable range, the stability of the composition is good, close to the effect of Example 1. In Example 3, the amount of acrylic acid / stearyl alcohol polyether-20 methacrylate copolymer was slightly reduced. Although the amount of microcrystalline cellulose and cellulose gum was increased, the main chain polymer was insufficient, the network node density was insufficient at 50°C, and slight delamination occurred.

[0048] Based on Examples 1, 4-5 and Table 1, it can be seen that in Examples 4 and 5, adjusting the mass ratio of Sphingomonas fermentation product extract and Panax notoginseng root extract within a suitable range resulted in good stability of the composition. In Example 5, the amount of Sphingomonas fermentation product extract was slightly reduced, and the composition showed slight stratification at 50°C.

[0049] Based on Examples 1, Comparative Examples 1-2, and Table 1, it can be seen that in Comparative Example 1, replacing the Sphingomonas fermentation product extract with an equal mass of Panax notoginseng root extract, and in Comparative Example 2, replacing the Panax notoginseng root extract with an equal mass of Sphingomonas fermentation product extract, the stability of the compositions deteriorated. This may be because, in Comparative Example 1, only Panax notoginseng root extract was used, resulting in weak interfacial adsorption strength, which could not effectively prevent the ripening and aggregation of oil droplets at high temperatures, leading to stratification at 45°C; in Comparative Example 2, only Sphingomonas extract was used, and although its high molecular weight polysaccharides could form an adsorption layer on the surface of oil droplets, there was no antioxidant protection, and the polysaccharide chains were prone to oxidative chain breakage at high temperatures, causing damage to the membrane integrity and a decrease in stability at 50°C. This indicates that the simultaneous use of the two can synergistically enhance the effect. The antioxidant capacity of Panax notoginseng root extract can protect the Sphingomonas extract and chemical sunscreens from oxidative degradation, maintain the durability of interfacial adsorption capacity, and form a dual protection of antioxidant and physical stability.

[0050] Based on Examples 1, 3, and Table 1, it is evident that in Comparative Example 3, replacing an equal mass of acrylic acid / stearyl alcohol polyether-20 methacrylate copolymer with polyquaternium-67 significantly degraded the stability of the composition. This is likely because polyquaternium-67 is a cationic polymer lacking carboxylic acid groups in its molecular structure. Consequently, it cannot form an effective dynamic hydrogen bond network with the hydroxyl groups of cellulose gum, making it difficult to construct a stable three-dimensional gel structure with appropriate yield stress. This results in the inability to effectively suspend the oil phase and sunscreen agent, ultimately leading to phase separation and stratification.

[0051] As can be seen from Example 1, Comparative Example 4, and Table 1, in Comparative Example 4, replacing an equal mass of Panax notoginseng root extract with Glycyrrhiza glabra root extract significantly worsened the stability of the composition. This may be because Glycyrrhiza glabra root extract may introduce additional ionizing components, interfering with the three-dimensional thickening network between the cellulose gum and the acrylic copolymer.

[0052] The sun protection factor (SPF) of the non-emulsified sunscreen compositions prepared in Examples 1-5 and Comparative Examples 1-4 was determined according to ISO 23675:2024. Three parallel experiments were set up for each group, and the average value was taken. The results are shown in Table 2.

[0053] Table 2

[0054] Based on Examples 1, Examples 2-3 and Table 2, it can be seen that in Examples 2 and 3, by adjusting the mass ratio of acrylic acid / stearyl alcohol polyether-20 methacrylate copolymer, microcrystalline cellulose and cellulose gum within a suitable range in the acrylic acid / stearyl alcohol polyether-20 methacrylate copolymer system, the sun protection factor of the composition is higher than 50 times.

[0055] Based on Examples 1, Examples 4-5 and Table 2, it can be seen that in Examples 4 and 5, by adjusting the mass ratio of Sphingomonas fermentation product extract and Panax notoginseng root extract within a suitable range, the SPF of the composition is higher than SPF 50.

[0056] Based on Examples 1, Comparative Examples 1-2, and Table 2, it can be seen that in Comparative Example 1, replacing an equal mass of the Sphingomonas fermentation product extract with Panax notoginseng root extract, and in Comparative Example 2, replacing an equal mass of the Panax notoginseng root extract with the Sphingomonas fermentation product extract, the SPF of the compositions decreased significantly. This may be because chemical sunscreens are prone to photodegradation under light. The free radical scavenging ability of Panax notoginseng root extract can protect the integrity of sunscreen molecules, while the Sphingomonas extract assists in antioxidation. The absence of either one will reduce the effective concentration of the sunscreen during preparation, storage, and testing, thereby leading to a decrease in sun protection performance.

[0057] Based on Examples 1, 3, and Table 2, it is evident that in Comparative Example 3, replacing an equal mass of acrylic acid / stearyl alcohol polyether-20 methacrylate copolymer with polyquaternium-67 significantly reduced the SPF of the composition. This is likely because replacing the acrylic acid / stearyl alcohol polyether-20 methacrylate copolymer with polyquaternium-67 degrades the composition's structure, leading to uneven distribution of the sunscreen agent within the system and consequently, a decrease in sun protection performance.

[0058] Based on Examples 1, 4, and Table 2, it can be seen that in Comparative Example 4, replacing an equal mass of Panax notoginseng root extract with Glycyrrhiza glabra root extract resulted in a decrease in the SPF of the composition. This may be because the ionized glycyrrhizic acid salts in Glycyrrhiza glabra root extract may interfere with the three-dimensional hydrogen bond network of cellulose gum-acrylic acid copolymer-microcrystalline cellulose, weakening the system's ability to suspend the sunscreen agent, accelerating particle sedimentation, and leading to a decline in sun protection performance.

[0059] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the products, methods and principles of this application should be covered within the scope of protection of this application.
