[0001] The invention relates to the technical field of cosmetic preparations, and in particular to an anti-wrinkle and repair caviar extract composition and a preparation method thereof. Background Art

[0002] Anti-aging cosmetics are designed to target the characteristics and causes of aging skin. On the basis of moisturizing and sun protection, active nutrients are added to enhance the skin's nutrient absorption, while further smoothing the skin, in order to delay aging and remove wrinkles. When the skin ages, the activity of the sebaceous glands decreases sharply, the skin barrier function is poor, bacteria are prone to grow and multiply, and metabolize a large amount of free fatty acids, further affecting skin health and forming a vicious cycle. At this stage, if bacteria are not inhibited, it is difficult to fundamentally fight wrinkles and aging by relying solely on moisturizing and sun protection.

[0003] Studies have found that the protein has broad-spectrum antibacterial activity and excellent cell penetration. Because it is composed entirely of natural amino acids, it has high biosafety and is safe for the human body when used. Compared with antibiotics, antimicrobial peptides are less likely to cause bacteria to develop drug resistance and are an excellent alternative to antibiotics. At the same time, high-protein caviar extract skin care products can improve cell mitochondrial function and have excellent anti-wrinkle repair effects.

[0029] Anti-aging cosmetics are designed to target the characteristics and causes of aging skin. On the basis of moisturizing and sun protection, active nutrients are added to enhance the skin's nutrient absorption, while further smoothing the skin, in order to delay aging and remove wrinkles. When the skin ages, the activity of the sebaceous glands decreases sharply, the skin barrier function is poor, bacteria are prone to grow and multiply, and metabolize a large amount of free fatty acids, further affecting skin health and forming a vicious cycle. At this stage, if bacteria are not inhibited, it is difficult to fundamentally fight wrinkles and aging by relying solely on moisturizing and sun protection.

[0030] Studies have found that the protein has broad-spectrum antibacterial activity and excellent cell penetration. Because it is composed entirely of natural amino acids, it has high biosafety and is safe for the human body when used. Compared with antibiotics, antimicrobial peptides are less likely to cause bacteria to develop drug resistance and are an excellent alternative to antibiotics. At the same time, high-protein caviar extract skin care products can improve cell mitochondrial function and have excellent anti-wrinkle repair effects.

[0031] However, when high-protein caviar extract is used at high levels in skin care products, it feels sticky and easily irritates.

[0032] In view of this, the present invention proposes an anti-wrinkle repairing caviar extract composition, which comprises, by weight: 10 to 20 parts of cocamidopropyl hydroxysulfonobetaine, 5 to 10 parts of ascorbic acid, 5 to 10 parts of glycerol, 3 to 15 parts of caviar extract, 3 to 5 parts of skin feel improver, 0.01 to 0.2 parts of antimicrobial agent, and the balance is deionized water.

[0033] As a zwitterionic surfactant, cocamidopropyl hydroxysultaine has excellent stability under both acidic and alkaline conditions, is low irritant and bactericidal, and can significantly improve the softness, conditioning and low-temperature stability of detergents. In anti-wrinkle repair compositions, it can help other ingredients penetrate the skin better.

[0034] Ascorbic acid has a powerful antioxidant effect, which can neutralize free radicals, reduce environmental damage to the skin, promote the synthesis of collagen, thereby reducing the formation of wrinkles, and inhibit the production of melanin, which has a whitening effect.

[0035] Glycerin is an excellent humectant that absorbs moisture from the air, keeps the skin moisturized, and reduces fine lines caused by dry skin.

[0036] Caviar extract is rich in protein, nucleic acid, water-soluble vitamins and minerals. It can accelerate the synthesis of collagen, increase skin elasticity, and has moisturizing and emollient functions. It can also improve cell mitochondrial function and reduce inflammation symptoms around aging skin tissue cells.

[0037] Skin feel improvers improve the feel of the skin, provide additional nourishment and protection, and strengthen the skin barrier function.

[0038] Antimicrobials are closely linked to the expression of skin lipids and protein genes, have antibacterial properties, help maintain skin health, prevent inflammation and infection, and can enhance the stability and effectiveness of other ingredients.

[0039] Cocoether-7 is added in a small amount in this solution as a solubilizer and emulsifier, which can greatly improve the chemical stability of the composition.

[0040] In this scheme, the synergistic effect between these components is mainly manifested in:

[0041] Antioxidant and Anti-Inflammatory: Ascorbic acid and caviar extract both have antioxidant properties that work together to fight free radicals and reduce inflammation, thereby slowing down skin aging.

[0042] Hydrates and Repairs: Glycerin and Caviar Extract work together to provide deep hydration, help repair the skin barrier and reduce water loss.

[0043] Promote collagen synthesis: Ascorbic acid and caviar extract can promote the synthesis of collagen, enhancing the elasticity and firmness of the skin.

[0044] Antimicrobial and Stabilization: Biocides and coceth-7 help maintain product stability while potentially enhancing the effects of other ingredients.

[0045] In some embodiments, the skin feel improving agent comprises C 18-21 Alkanes and plant-extracted lipids, wherein the plant-extracted lipids include at least one of camellia oil, olive oil, grape seed oil and lycopene.

[0046] C 18-21 Alkanes are highly pure, biodegradable emollients that have excellent compatibility with all oils and fats, used as emollients and solvents to give products a soft texture, and are inert and very stable.

[0047] Camellia oil is rich in tea polyphenols and fatty acids. Tea polyphenols can inhibit bacterial growth, maintain and moisturize the skin due to its flavanols and antioxidant and antibacterial biological activities. Olive oil is rich in antioxidants and vitamin E, which can moisturize and protect the skin. Grape seed oil is rich in nutrients such as polyunsaturated fatty acids, tocopherols, phytosterols and phenolic substances, and has multiple physiological effects such as antioxidant, anti-inflammatory and antibacterial. Lycopene is a carotenoid with multiple physiological functional activities such as quenching singlet oxygen, scavenging free radicals, and inhibiting lipid peroxidation.

[0048] Preferably, the skin feel improving agent comprises C 18-21 Alkanes and lycopene.

[0049] Preferably, the skin feel improving agent comprises C 18-21 Alkanes and grape seed oil and lycopene in a mass ratio of 1:1.

[0050] In this solution, the skin feel improver of the above-mentioned components can increase the moisturizing and refreshing feeling while reducing the sticky feeling.

[0051] In some embodiments, the C 18-21 The mass ratio of alkane to the plant extracted lipid is (10-1):(1-5).

[0052] In some embodiments, C 18-21 The mass ratio of alkane to plant-extracted lipid is any value in the range of (10 to 1): (1 to 5) such as 10:1, 10:3, 10:4, 9:1, 9:2, 9:3, 9:4, 9:5, 8:1, 7:1, 6:1, 5:1, 4:1, 3:1, 2:1, 1:1, 1:2, 1:3, 1:4, 1:5, 9:2, 7:3, 5:4, 3:1, 2:1, 5:1.7, 5:3.3, 8:1.9, etc. Preferably, C 18-21 The mass ratio of alkanes to plant-extracted lipids was 3:2.

[0053] In some embodiments, the antimicrobial agent comprises one of protamine, climbazole, and ketoconazole.

[0054] Preferably, the antimicrobial agent includes protamine, which is a basic protein rich in basic amino acids present in mature fish sperm and has broad-spectrum antibacterial activity. At the same time, in this solution, protamine can combine with DNA through electrostatic action to form a complex as a gene carrier, thereby enhancing the cell penetrability of DNA and enhancing the use effect of the fish roe extract composition.

[0055] In some embodiments, the anti-wrinkle repair caviar extract composition includes 0.5 to 3 parts of a pH adjuster by weight, and the pH adjuster includes at least one of citric acid, sodium citrate, malic acid, sodium malate, fumaric acid, sodium fumarate, succinic acid, sodium succinate, sodium hydroxide, and sodium monohydrogen phosphate.

[0056] Citric acid and sodium citrate are mainly used as chelating agents, buffers, and acid-base regulators in cosmetics. They capture and neutralize metal ions that may change the quality and stability of skin care products. They can also be used as natural preservatives. They can not only adjust the pH value, but also accelerate the renewal of keratin, help the melanin in the skin to peel off, shrink pores, dissolve blackheads, and have a moisturizing and whitening effect on the skin.

[0057] Malic acid and sodium malate act as pH adjusters and moisturizers, but they are somewhat irritating to the skin.

[0058] Fumaric acid and sodium fumarate are buffers and pH adjusters. They can also enhance the stability of the formula and increase the moisture content and moisturizing ability of the skin.

[0059] Sodium succinate can promote skin cell metabolism, accelerate skin regeneration and repair, and also has multiple functions such as antioxidant, anti-inflammatory and moisturizing.

[0060] In order to solve the above problems, the present invention also provides a method for preparing the above anti-wrinkle and repair caviar extract composition, comprising the following steps:

[0061] S1. Mix deionized water, ascorbic acid and cocoether-7 to obtain a first mixture;

[0062] Deionized water is used as a solvent and cocoether-7 is used as a stabilizer to dissolve ascorbic acid to form a stable aqueous solution.

[0063] S2. The antimicrobial agent, the skin feel improver, and the cocamidopropyl hydroxysulfobetaine are dissolved in a solvent, and the solvent is removed by heating to obtain a uniform film formed on the inner surface of the container;

[0064] The film is formed by evaporating the solvent. The film serves as a carrier for controlling the release of the active substance, which is beneficial to the slow release of the active ingredient and the slow mixing and homogenization with the first mixture in the next step to avoid side reactions.

[0065] S3. adding the first mixture to the container, adding glycerol to completely dissolve the film, adding to a homogenizing device, homogenizing, standing to degas, and sterilizing with ultraviolet light to obtain a second mixture;

[0066] Glycerol can help dissolve the film and form a uniform solution, homogenization can ensure that the ingredients in the mixture are evenly distributed, and UV sterilization can effectively kill microorganisms to ensure the stability and safety of caviar extract.

[0067] S4. Add a pH regulator to the second mixture to obtain a gel product, add the fish roe extract to the gel product and disperse it evenly to obtain an anti-wrinkle and repair fish roe extract composition.

[0068] Caviar extract is a nutrient- and antioxidant-rich ingredient that nourishes and protects the skin. Evenly dispersed in the gel, it ensures product effectiveness and consistency.

[0069] In some embodiments, in step S1, the stirring rate of the mixing is 1500-2000 rpm; in step S3, the homogenization pressure is 13 MPa-20 MPa.

[0070] In some embodiments, the stirring rate of the mixture of deionized water, ascorbic acid and coceth-7 is any value between 1500 rpm and 2000 rpm, such as 1500 rpm, 1600 rpm, 1700 rpm, 1800 rpm, 1900 rpm, and 2000 rpm.

[0071] In some embodiments, the homogenization pressure is any value between 13 MPa and 20 MPa, such as 13 MPa, 14 MPa, 15 MPa, or 20 MPa.

[0072] In some embodiments, in step S2, the solvent is an ethanol solution with a volume concentration of 80% to 95%, and the mass of the ethanol solution is 3 to 5 times the total mass of the antimicrobial agent, the skin feel improver, and cocamidopropyl hydroxysulfonyl betaine.

[0073] The concentration and amount of ethanol added will affect the performance of the film. An appropriate amount of ethanol can help form a uniform film, but if too much is added, it may cause the film to dry too quickly, affecting the uniformity and quality of the film.

[0074] In some embodiments, in step S4, the pH value of the system is adjusted to 3 to 4.5 after adding the pH adjuster. The pH controls the flow properties of the gel so that the fish roe extract can be evenly dispersed in the system.

[0075] Example 1

[0076] In parts by weight, 5 parts of ascorbic acid and 1 part of cocoether-7 were added to 95 parts of deionized water, and the mixture was put into a high-speed stirrer and stirred at a rate of 2000 rpm to obtain a first mixture;

[0077] 0.15 parts of protamine, 4 parts of skin feel improver (2 parts of C 18-21 alkane, 1 part grape seed oil and 1 part lycopene), 16 parts cocamidopropyl hydroxysultaine are dissolved in an ethanol solution with a volume concentration of 80% to 95%, and the ethanol is removed by a rotary evaporator, and the vacuum degree is set to 0.02 and the temperature is 50°C to obtain a uniform film formed on the inner surface of the container to ensure that the solvent is completely evaporated without destroying the active ingredients;

[0078] The first mixture is added into the container, 7 parts of propylene glycol is added to completely dissolve the film, and the mixture is added into a homogenizing device for homogenization at a pressure of 15 MPa. The mixture is allowed to stand for degassing and sterilized by ultraviolet light to obtain a second mixture. 1 part of citric acid is added into the second mixture, and the pH value of the system is adjusted to 4.5 to obtain a gel product. 8 parts of fish roe extract are added into the gel product for ultrasonic dispersion to obtain an anti-wrinkle and repairing fish roe extract composition.

[0080] In Examples 2-6, except that the components used in preparing the anti-wrinkle repair caviar extract composition are added as shown in Table 1, the rest are as shown in Example 1.

[0081] Comparative Example 1

[0082] No skin feel improver was added, and the rest was as in Example 1.

[0083] Comparative Example 2

[0084] Methylparaben was used as the antimicrobial agent, and the others were as in Example 1.

[0085] Table 1. Components of Examples and Comparative Examples (parts by weight)

[0086]

[0087] Performance Testing

[0088] Relevant performance tests were performed on the anti-wrinkle and repairing caviar extract compositions prepared in Examples 1-6 and Comparative Examples 1-2.

[0089] 1. Irritation Assessment

[0090] A skin patch test was conducted on 20 healthy adult men and women aged 20 to 40 years to evaluate the skin irritation of the cosmetic composition. The composition in Table 1 was shaken and mixed, and then a skin patch test was performed on the back for 48 hours at a unit of 20 μl / chamber. The patch was removed after 1 hour of application, and the degree of skin irritation was evaluated at 24 hours and 48 hours. The results were recorded according to the skin reaction grading standard in the "Cosmetic Hygiene Standards", with 0 indicating no irritation and 4 indicating significant irritation. The test results are shown in Table 2.

[0091] 2. Anti-aging test

[0092] The anti-aging experiment was carried out using du800 UV-visible spectrophotometer (Beckman Company, USA). The original solvent was adjusted to zero point, and the absorbance measured at 515nm was Ai; the same method was used for the 0.1mL solvent + 2mL experimental method: 0.1mL sample solution was taken, 2mL of 60μmol / L DPPH solution was added and mixed, and then placed for 30min. The absorbance was measured by mixing DPPH solution and the extreme was Ac; 0.1mL sample solution + 2mL solvent was mixed and the absorbance was measured and the extreme was Aj. The free radical scavenging rate was calculated according to the following formula. Scavenging rate (%) = [1-(Ai-Aj) / Ac] × 100%, where Aj reflects the contribution of the sample itself to the absorbance; Ai is the absorbance value of the sample after the action of DPPH; Ac is the absorption of DPPH itself at the measured wavelength. The test results are shown in Table 2.

[0093] 3. Antibacterial test

[0094] A 28-day microbial colony count residual test was conducted to test the percentage decrease in the colony count of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Aspergillus niger and Candida albicans. The antibacterial qualification was judged in accordance with the "Method for Evaluation of Cosmetic Preservative Effectiveness". The total colony count of bacteria decreased by 99.9% on the 7th day after adding the spike, and there was no growth on the 28th day. The fungi decreased by 99.0% on the 14th day and there was no growth on the 28th day, and were judged to be qualified.

[0095] Table 2. Irritation and anti-aging evaluation results

[0096]

[0097]

[0098] From the data in Table 2, it can be seen that the caviar extract compositions prepared in Examples 1-6 have good safety in use, weak irritation, and are not prone to allergic reactions. 18-21 Alkanes, camellia oil, olive oil, grape seed oil or lycopene, the protein components therein may pose a certain risk of allergenicity.

[0099] The compositions of Examples 1-6 of the present invention have good free radical scavenging ability, and the scavenging rates are higher than those of the comparative examples, and the free radical scavenging ability of Example 1 is the best, thereby being able to obtain a better anti-wrinkle repair effect.

[0100] 4. Sensory evaluation

[0101] Women aged 20 to 30 were randomly selected, 20 subjects from oily skin, dry skin and sensitive skin groups, a total of 60 subjects, to evaluate the moisturizing and sticky feeling. After the composition was shaken and mixed, it was applied to the skin and evaluated 10 minutes later. The sensory evaluation was performed using a 5-point system, and the average was calculated and included in the following Table 3. Excellent is 5 points, excellent is 4 points, ordinary is 3 points, poor is 2 points, and extremely poor is 1 point. In the sticky feeling evaluation, feeling non-sticky is rated as 5 points, and feeling sticky is rated as 1 point. In the refreshing feeling evaluation, feeling refreshing is rated as 5 points, and feeling not refreshing is rated as 1 point.

[0102] Table 3. Sensory evaluation results

[0103] Moisturizing effect Sticky feeling Refreshing feeling Example 1 4.23 3.53 4.65 Example 2 4.89 3.66 4.2 Example 3 4.55 4.09 4.2 Example 4 4.6 3.99 4.05 Example 5 4.5 3.93 4.56 Example 6 3.7 3.90 4.68 Comparative Example 1 3.69 4.5 2.28 Comparative Example 2 4.23 4.2 3.35

[0104] From the data in Table 3, it can be seen that the results of Comparative Examples 1 and 2 show that not adding a skin feel improver or replacing the antimicrobial agent not only affects the overall moisturizing, anti-aging and antibacterial effects of the formula, but also has a significant negative impact on the actual sensory properties of the product.

[0105] The above test results confirm that in the anti-wrinkle and repairing caviar extract composition provided by this scheme, the caviar extract not only nourishes the skin, but also promotes the synthesis of collagen, enhances the elasticity and firmness of the skin, ascorbic acid can directly neutralize free radicals, has antioxidant and anti-inflammatory effects, glycerol and skin feel improvers provide additional moisturizing and anti-aging effects, antimicrobial agents and cocamidopropyl hydroxysulfonyl betaine promote the penetration of other ingredients, and cocoether-7 is added in small amounts in this scheme as a solubilizer and emulsifier, which can greatly improve the chemical stability of the composition and further enhance the protection and repair effects of the product. The synergistic effect of the above ingredients helps to improve the antibacterial and anti-wrinkle repair effect, deeply penetrate the caviar extract and other protein ingredients into the skin, enhance the elasticity and moisturizing ability of the skin, provide antioxidant protection, reduce signs of skin aging, and reduce the stickiness and irritation that may be caused by high protein ingredients.
