Description

Technical Field

[0001] The present application relates to the technical field of cosmetics, and in particular to a DNA repair essence containing sodium and a preparation method thereof. Background Art

[0002] Human skin is exposed to external factors such as ultraviolet rays and dry air, which can easily cause skin damage, dehydration, wrinkles, and cracks, leading to accelerated skin aging. As people's living standards improve, they are paying more and more attention to skin care, and essences are products that have a significant effect on the skin.

[0003] Essence is a highly concentrated skincare product containing active ingredients such as antioxidants, moisturizers, and repair factors. These ingredients penetrate deeply into the skin's base layer, delivering highly effective skincare benefits. Prior art anti-oxidant and anti-aging essences include tea polyphenols, biological agents, chelating agents, emollients, moisturizers, purified water, and thickening emulsifiers. The preparation method involves mixing all of these ingredients and stirring them evenly at a certain temperature to produce the essence. However, while this essence enhances its antioxidant effect by combining biological agents with tea polyphenols, biological agents are sensitive to the environment and easily inactivated by light, heat, and oxygen, thus reducing the essence's effectiveness. Summary of the Invention

[0004] In order to improve the problem of unstable antioxidant effect of essence, the present application provides a DNA sodium repair essence and a preparation method thereof.

[0005] This application provides a DNA repair essence containing sodium, which adopts the following technical solution: A sodium DNA repair essence comprises the following raw materials, measured by weight: 80-100 parts of water, 1-5 parts of panthenol, 1-5 parts of glycereth-26, 1-5 parts of a moisturizer, 0.1-5 parts of trehalose, 0.1-2 parts of inositol, 0.1-2 parts of 1,2-hexanediol, 0.1-2 parts of p-hydroxyacetophenone, 0.01-1 parts of sodium DNA, 0.1-2 parts of PEG / PPG-14 / 7 dimethyl ether, 0.01-1 parts of allantoin, 0.01-1 parts of acrylates / C10-30 alkyl acrylate crosspolymer, 0.01-1 parts of arginine, 0.01-1 parts of hydrolyzed sodium hyaluronate, 0.01-1 parts of ectoine, 0.01-1 parts of disodium EDTA, and 0.001-0.5 parts of a skin conditioner.

[0006] By adopting the above technical solution, Glycereth-26 has excellent moisturizing properties, forming a moisturizing film on the skin surface, reducing water loss and improving the skin's touch. Trehalose forms a protective film on the skin surface, preventing dryness and enhancing the skin's resistance to stress. Panthenol penetrates deep into the skin's underlying layers, enhancing its moisturizing capacity, promoting epithelial cell regeneration, repairing damaged skin barriers, alleviating dryness and flaking, and keeping the skin soft and moisturized. Inositol participates in the synthesis of cell membrane phospholipids, strengthening the skin's barrier function. Tetrahydropyrimidine carboxylic acid has antioxidant and repairing properties, neutralizing free radicals and reducing oxidative damage to the skin. It also promotes collagen synthesis, enhancing skin elasticity and firmness.

[0007] 1,2-Hexanediol has both moisturizing and antibacterial properties, while p-hydroxyacetophenone is a mild preservative. The two work together to ensure the product's microbial stability and reduce the irritation of traditional preservatives. Sodium DNA repairs skin damage and promotes skin cell regeneration, improving skin texture and elasticity and reducing the appearance of wrinkles and fine lines. PEG / PPG-14 / 7 dimethyl ether helps disperse poorly water-soluble ingredients, making the serum system more uniform and stable. Acrylates / C10-30 Alkyl Acrylate Crosspolymer forms a thin film on the skin's surface, facilitating the adhesion and penetration of other ingredients while also improving skin texture. Arginine regulates the skin's pH balance, promotes skin cell metabolism, and enhances the skin's self-repair ability. Hydrolyzed sodium hyaluronate is a small molecule form of hyaluronic acid that quickly penetrates deep into the skin, replenishing moisture and nutrients and promoting skin cell repair and regeneration.

[0008] Allantoin has moisturizing and repairing properties. It can promote skin cell metabolism, promote the shedding of dead keratinocytes, stimulate fibroblasts to synthesize hyaluronic acid, relieve inflammation, and reduce the irritation of surfactants to the skin. Disodium EDTA can bind to metal ions, preventing them from oxidizing and decomposing other ingredients in the product, improving product stability and extending its shelf life. Humectants can absorb moisture from the air, providing long-lasting moisturizing effects for the skin. Skin conditioners can regulate the skin's oil secretion and improve the skin's microcirculation, making the skin healthier and more comfortable. The above-mentioned multiple components work synergistically to enhance moisturizing, combining deep moisturizing with surface moisturizing, repairing the skin, and promoting skin cell regeneration. The resulting essence has good stability and extends the product's shelf life.

[0009] Preferably, the moisturizing agent consists of water, butylene glycol and sodium polyglutamate in a mass ratio of 1:6-7:25-26.

[0010] By adopting the above technical solution, butylene glycol has moisturizing, solvent, and penetration-promoting effects, which can help other ingredients better dissolve and penetrate the skin, and can also regulate the skin's moisture balance. Sodium polyglutamate is a powerful moisturizing and water-locking agent, absorbing moisture from the air to replenish the skin and enhance the skin's water retention capacity. The three work together to enhance moisturizing: water replenishes basic moisture, butylene glycol promotes the penetration of other ingredients, and sodium polyglutamate locks in moisture, collectively providing comprehensive moisturization for the skin. Sodium polyglutamate can absorb sodium DNA to form a film on the skin surface, extending the residence time of active ingredients, enhancing repair efficiency, reducing water loss, and synergizing with water and butylene glycol to maintain skin hydration. Butylene glycol improves solubility and stability, ensuring the synergistic effect of moisturizers and extending the product's shelf life.

[0011] Preferably, the moisturizing agent is composed of hydrogenated lecithin, Haematococcus pluvialis extract, phytosterols, tocopherol and astaxanthin in a mass ratio of 85-90:4-5.5:2.7-3:1.8-2:1.

[0012] By employing this technical solution, hydrogenated lecithin exhibits excellent moisturizing properties, absorbing moisture from the air and locking it into the skin. It directly encapsulates sodium DNA, enabling transdermal penetration and cell membrane penetration. Haematococcus pluvialis extract, rich in astaxanthin, possesses strong antioxidant properties, scavenging free radicals and reducing oxidative damage to skin moisture and cells. It also works synergistically with sodium DNA to inhibit DNA damage caused by oxidative stress. Phytosterols and hydrogenated lecithin synergize to repair and protect the skin barrier, enhancing moisture retention and maintaining moisture balance, while also improving skin stability and tolerance. Tocopherol, also known as vitamin E, is an antioxidant that protects the skin from free radical damage, slows aging, and enhances its moisturizing function. It synergizes with astaxanthin to enhance its antioxidant and moisturizing properties. Astaxanthin, a powerful antioxidant, effectively scavenges free radicals, protects skin cells from oxidative damage, maintains skin health, and enhances its moisturizing capacity. The synergistic combination of biomimetic lipids and potent antioxidants significantly enhances the repair essence's barrier repair capabilities and antioxidant efficacy, achieving a hydrating and moisturizing effect.

[0013] Preferably, the raw materials further include a mixture of oyster shell powder, jasmine extract and hydroxyethyl cellulose in a mass ratio of 6-7:3-5:1.

[0014] By adopting the above technical solution, oyster shell powder contains a variety of trace elements that can enhance the skin's antioxidant capacity, promote skin metabolism, improve dullness, enhance skin brightness, relieve skin allergies, improve skin tolerance, and enhance moisturizing ability. Jasmine flower extract can eliminate superoxide free radicals, have antioxidant and anti-aging effects, reduce melanin production, promote whitening, maintain skin moisture, and prevent dryness. Hydroxyethyl cellulose, as a film-forming agent, can reduce damage to the skin caused by environmental factors such as ultraviolet rays, indirectly enhancing antioxidant protection, reducing water loss, and enhancing moisturizing effects.

[0015] Jasmine extract can be adsorbed on the particle surface and pores of oyster shell powder, and hydroxyethyl cellulose can coat the oyster shell powder, so that the oyster shell powder and jasmine extract are tightly bonded. The resulting mixture has excellent stability in improving skin condition. Oyster shell powder, jasmine extract and hydroxyethyl cellulose have a synergistic effect, which greatly enhances the barrier protection, long-lasting antioxidant and skin feel optimization composite functions of the mixture, and enables the active ingredients in the components to be slowly released into the deep layers of the skin, prolonging the protection time and improving the essence's repair, moisturizing and skin brightening effects.

[0016] Preferably, the method for preparing the oyster shell powder comprises the following steps: (1) soaking the oyster shell powder in acetic acid for 1-2 hours, washing with water, calcining at 500-600° C. for 3-4 hours, then dispersing in deionized water, adding trypsin, stirring at 45-50° C. for 2-4 hours, filtering, and drying to obtain pretreated oyster shell powder; (2) dispersing titanium dioxide in deionized water, adding the pretreated oyster shell powder and cocamidopropyl betaine in step (1), stirring for 2-3 hours, filtering, and drying to obtain a mixture; (3) dissolving viscose mastic gum in an ethanol aqueous solution, adding hydroxypropyl starch, stirring at a temperature of 60-65° C. for 30-35 minutes to obtain a mixed solution, adding the mixed solution to the mixture of step (2), stirring evenly, and drying to obtain oyster shell powder.

[0017] Through this technical solution, acetic acid removes impurities and soluble components from the oyster shell powder. Calcination decomposes the organic matter in the oyster shell powder, increasing its specific surface area and making it more susceptible to subsequent interaction with other ingredients. Trypsin hydrolyzes the protein components of the oyster shell powder, producing bioactive small molecule peptides or other active substances, thereby improving their bioavailability and efficacy.

[0018] Titanium dioxide gives the fiber a light-shielding or whitening function, enhances the fiber's ability to scatter ultraviolet rays, and provides a sun protection effect. Titanium dioxide can be loaded in the structural pores of the pretreated oyster shell powder. Cocamidopropyl betaine has good dispersing, wetting and emulsifying properties, which helps to uniformly disperse the pretreated oyster shell powder and titanium dioxide, and may promote the combination between oyster shell powder particles and titanium dioxide.

[0019] After drying, the viscose mastic gum forms a flexible film, and the hydroxypropyl starch increases the viscosity of the film and wraps the mixture particles, so that the pretreated oyster shell powder and titanium dioxide are tightly bonded. The viscose mastic gum and hydroxypropyl starch will form a protective film on the surface of the oyster shell powder. This film can enhance the stability of the oyster shell powder and prevent it from being oxidized, damp or reacting adversely with other ingredients during subsequent use or storage. It also has a sustained-release function to achieve the slow release of active ingredients, which helps to prolong the effect of the active ingredients and make the oyster shell powder more easily and evenly distributed in the essence, and better interact with other ingredients, so as to more effectively exert its antioxidant, whitening, repair and other effects in the essence, thereby improving the overall performance of the essence.

[0020] Preferably, the mass ratio of the oyster shell powder, titanium dioxide and viscose mastic gum is 1:0.6-0.7:0.1-0.2.

[0021] By adopting the above technical scheme, the mass ratio between oyster shell powder, titanium dioxide and viscose mastic gum is further limited, and the oyster shell powder of the processing obtained has excellent comprehensive properties. Oyster shell powder is rich in calcium carbonate, amino acids, and trace elements (such as zinc and copper). It may be absorbed by the skin or form a protective layer, which helps improve the skin barrier function and enhance cell metabolism. Titanium dioxide can be loaded in the porous structure of the oyster shell powder after calcination, thereby improving the structural strength and adsorptivity of the oyster shell powder. Viscose mastic gum has good film-forming properties and can form a breathable protective film on the surface of the oyster shell powder, thereby improving the stability between the oyster shell powder and the titanium dioxide, thereby preventing it from being oxidized or degraded during use and extending the shelf life of the product. The three ingredients cooperate with each other to play a synergistic effect, so that the essence has better anti-oxidation, whitening, moisturizing, repairing and other effects.

[0022] Preferably, the preparation method of the jasmine extract comprises the following steps: dispersing jasmine in deionized water, adding β-glucosidase, pectinase, and cellulase, adjusting the pH to 4.2-4.8, performing enzymolysis at 38-40°C for 1-2 hours, inactivating, filtering, and obtaining a slurry; adding nano-silica, xanthan gum, and Tween 80, stirring at a temperature of 40-45°C for 2-3 hours, and drying to obtain the jasmine extract.

[0023] By adopting the above technical solution, the plant cell walls are broken down by the action of enzymes, releasing the active ingredients in jasmine flowers. β-glucosidase decomposes the glycosides (such as flavonoid glycosides and coumarin glycosides) in jasmine flowers, releasing free active ingredients (such as flavonoids and phenols), thereby enhancing the antioxidant and anti-inflammatory effects. Pectin and cellulase destroy the pectin and cellulose structure of the plant cell walls, allowing the effective ingredients in the cells (such as volatile oils, polysaccharides, and amino acids) to be fully dissolved, thereby improving the extraction efficiency. The resulting active ingredients effectively scavenge free radicals, reduce oxidative damage, delay skin aging, enhance the skin's moisturizing ability, keep the skin hydrated and soft, reduce spots and dullness, and make the skin brighter and more even.

[0024] Nanosilica has excellent antioxidant properties, further enhancing the serum's antioxidant effects and protecting the skin from oxidative damage. Xanthan gum improves the extract's system stability, forming a three-dimensional network that encapsulates the nanosilver and floral fragrance molecules. This tightly binds the nanosilica and jasmine extract, controlling its sustained release and preventing post-freeze-drying stratification. Furthermore, in skincare products, it improves skin feel. Tween 80 increases the solubility of hydrophobic ingredients (such as volatile oils), promoting uniform dispersion and preventing oil-water stratification.

[0025] The dried jasmine flower extract can eliminate free radicals and delay skin aging. The three work synergistically to enhance the comprehensive performance of the essence, making the essence have better antioxidant, moisturizing, soothing and repairing effects, significantly improving skin condition and enhancing skin health.

[0026] Preferably, the mass ratio of the jasmine flowers, nano-silica and xanthan gum is 1:0.2-0.3:0.07-0.09.

[0027] By adopting the above technical solution and further limiting the mass ratio of jasmine flower, nano-silica, and xanthan gum within a certain range, the resulting jasmine flower extract has excellent comprehensive properties. Jasmine flower extract is rich in antioxidant ingredients, such as flavonoids and polyphenols, which can effectively scavenge free radicals, reduce free radical damage to the skin, and delay skin aging. Nano-silica has good adsorption, antioxidant properties, and good stability. Xanthan gum can significantly increase the viscosity of the aqueous phase and has film-forming properties. It encapsulates the jasmine flower extract and nano-silica, stabilizes the active ingredients of the jasmine flower extract, improves the stability of the subsequent jasmine flower extract in the essence, and enhances the essence's antibacterial effect, achieving a long-lasting, fragrant, antibacterial, and antioxidant effect.

[0028] In a second aspect, the present application also provides a method for preparing a DNA sodium repair essence, comprising the following steps: mixing the components, stirring at a temperature of 30-35°C for 3-4 hours, and obtaining a DNA sodium repair essence.

[0029] By adopting the above technical solution and the above preparation method, the operation is simple and the mixing is uniform, which helps to improve the antibacterial, whitening and moisturizing effects of the preparation of the DNA sodium repair essence. The obtained DNA sodium repair essence has a good shelf life.

[0030] In summary, this application has the following beneficial effects: 1. The various components in this application work together to enhance moisturizing, combine deep moisturizing with surface moisturizing, repair the skin, and promote the regeneration of skin cells. The resulting essence has good stability and extends the shelf life of the product.

[0031] 2. The sodium DNA in this application has the function of repairing skin damage and promoting skin cell regeneration, which can improve the texture and elasticity of the skin and reduce the appearance of wrinkles and fine lines.

[0032] 3. The sodium polyglutamate in this application can adsorb sodium DNA to form a film on the skin surface, prolong the residence time of the active ingredients, enhance the repair efficiency, reduce water loss, and work together with water and butylene glycol to maintain skin hydration and extend the shelf life of the product.

[0069] Performance testing The performance of the DNA sodium repair essence prepared in Examples 1-14 and Comparative Example 1 was tested; 1. DPPH-free radical scavenging test: According to the "Cosmetics-Free Radical (DPPH) Scavenging Test Method (T / SHRH006-2018)", the DPPH free radical scavenging rate (%) of the DNA sodium repair essence obtained in the example and the comparative example was tested respectively.

[0070] 2. Moisture absorption and moisturizing effect: The interior of a desiccator filled with a saturated K2SO4 aqueous solution was maintained at a relative humidity of 40% (RH = 40%). 0.5 g of each of the Example and Comparative Example essences (samples), dried to constant weight, was weighed and placed in small weighing bottles. Each sample was then placed in the desiccator. The desiccators were then kept at a constant temperature of 20°C. The samples were allowed to stand for 24 hours. The mass of each sample was then weighed and the moisture absorption rate was calculated: Moisture absorption rate = (m2-m1) / m1×100%; m1 is the initial mass of the sample, and m2 is the mass of the sample after 24 hours.

[0071] Accurately weigh 0.5 g of the essence of the Examples and Comparative Examples, dried to constant weight, and add 10% of the sample weight of deionized water into a small weighing bottle. Place each of the bottles in the above-mentioned desiccators. Place the desiccators in a constant temperature environment at 20°C and let them stand for 24 hours. Weigh the mass of each sample and calculate the moisturizing rate: Moisture retention rate = m4 / m3×100%; m3 is the initial moisture mass of the sample, and m4 is the moisture mass of the sample after 24 hours.

[0072] 3. The subjects were 35-45 years old, both men and women. Each subject applied the essence prepared in the examples and comparative examples to the face and neck (2cm*2cm test area) using the same method. The test environment temperature was 20°C and the humidity was 40%. The test sample is 3.0mg / cm 2 Each sample was applied in the morning and evening for one week. After application, the skin was scored for changes in skin brightening and wrinkle appearance.

[0073] Scoring criteria (total score 100 points) Skin brightening changes: obvious skin brightening 80-100, general skin brightening 51-79, not obvious skin brightening 0-50.

[0074] Wrinkle changes: Significant wrinkle reduction (80-100), moderate wrinkle reduction (51-79), and no wrinkle change (0-50). See Table 1 for test results.

[0075] Table 1 Test data of embodiments and comparative examples As can be seen from Table 1, the repair essence containing sodium DNA prepared in Examples 1-2 of the present application has good whitening and anti-wrinkle effects, as well as moisture absorption and moisturizing effects. Among them, the free radical scavenging rate of Example 1 is 91.35%, the moisture absorption rate is 6.8%, the moisturizing rate is 67.54%, the skin brightening change score is 90, and the wrinkle change score is 87. It can be seen that the multiple components of the repair essence prepared in the present application work synergistically to enhance moisturizing, combine deep moisturizing with surface moisturizing, repair the skin, promote skin cell regeneration, have good stability, and extend the shelf life of the product.

[0076] Example 3-4 changes the mass ratio of water, butylene glycol, sodium polyglutamate, hydrogenated lecithin, Haematococcus pluvialis (HAEMATOCOCCUS PLUVIALIS) extract, phytosterols, tocopherol (vitamin E), and astaxanthin respectively. As can be seen from Table 1, the free radical scavenging rate, moisture absorption rate, moisturizing rate, skin brightening change, and wrinkle change test effects of Example 3-4 are all significantly worse than those of Example 1-2, indicating that water, butylene glycol, and sodium polyglutamate work together to maintain skin moisture, improve solubility and stability, and extend the shelf life of the product. Hydrogenated lecithin, Haematococcus pluvialis (HAEMATOCOCCUS PLUVIALIS) extract, phytosterols, tocopherol (vitamin E), and astaxanthin multiple components work together to significantly enhance the barrier repair ability and antioxidant time efficiencies of the repair essence through biomimetic lipids and strong antioxidant combinations, achieving the effect of locking in water and moisturizing.

[0077] The raw materials of Examples 5-6 also include a mixture of oyster shell powder, jasmine extract, and hydroxyethyl cellulose. As can be seen from Table 1, the free radical scavenging rate, moisture absorption rate, moisturizing rate, skin brightening change, and wrinkle change test results of Examples 5-6 are significantly better than those of Examples 1-2, indicating that there is a synergistic effect between oyster shell powder, jasmine extract, and hydroxyethyl cellulose, which greatly enhances the barrier protection, long-lasting antioxidant, and skin feel optimization composite functions of the mixture, allowing the active ingredients in the components to be slowly released into the deep layers of the skin, prolonging the protection time and improving the repair, moisturizing, and skin brightening effects of the essence.

[0078] The preparation methods of oyster shell powder in Examples 7-8 do not add titanium dioxide and viscose mastic gum respectively. Examples 9-10 change the mass ratio of oyster shell powder, titanium dioxide and viscose mastic gum. As can be seen from Table 1, the free radical scavenging rate, moisture absorption rate, moisturizing rate, skin brightening change, and wrinkle change test effects of Examples 7-8 are significantly worse than those of Examples 5-6 and Example 9. The corresponding test effect of Example 10 is significantly better than that of Examples 7-8, but worse than that of Examples 5-6. This shows that viscose mastic gum can form a breathable protective film on the surface of oyster shell powder, improve the stability between oyster shell powder and titanium dioxide, prevent it from being oxidized or degraded during use, and extend the shelf life of the product. The three ingredients cooperate with each other to play a synergistic role, so that the essence has better antioxidant, whitening, moisturizing, and repair effects.

[0079] The preparation methods of jasmine extracts in Examples 11-12 do not add nano-silica and xanthan gum, respectively. Examples 13-14 vary the mass ratio of jasmine, nano-silica, and xanthan gum. As can be seen from Table 1, the free radical scavenging rate, moisture absorption rate, moisturizing rate, skin brightening change, and wrinkle change test results of Examples 11-12 are significantly worse than those of Examples 5-6 and Example 13. The corresponding test results of Example 14 are significantly better than those of Examples 11-12, but worse than those of Examples 5-6. This shows that xanthan gum can significantly increase the viscosity of the aqueous phase, has film-forming properties, encapsulates jasmine extract and nano-silica, stabilizes the active ingredients of the jasmine extract, improves the stability of the subsequent jasmine extract in the essence, and improves the antibacterial effect of the essence by slowly releasing nano-silica, achieving a long-lasting, fragrant, antibacterial, and antioxidant effect.

[0080] In Comparative Example 1, no DNA sodium is added. As can be seen from Table 1, the test effects of free radical scavenging rate, moisture absorption rate, moisturizing rate, skin brightening change, and wrinkle change are significantly worse than those of Examples 1-2, indicating that DNA sodium has the effect of repairing skin damage and promoting skin cell regeneration, and can improve the texture and elasticity of the skin and reduce the appearance of wrinkles and fine lines.

[0081] 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 non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
