Description

Technical Field

[0001] The present application relates to the field of cosmetics for external use on the eyes, and more specifically, to a double-resistance eye cream and a preparation method thereof. Background Art

[0002] Eye skin is one of the most delicate and thinnest areas of human skin. Its special physiological structure and function make it more susceptible to the dual influence of external environment and internal factors, which leads to skin aging, sagging and wrinkle formation. With the accelerated pace of modern life and the increasing severity of environmental pollution, the demand for anti-oxidation and firming and anti-wrinkle of eye skin is becoming more urgent.

[0003] Oxidation is a key factor in the aging process of the skin around the eyes. The generation and accumulation of free radicals will damage the cell structure of the skin around the eyes, leading to the degradation of collagen and elastic fibers, which in turn causes aging phenomena such as sagging skin and deepening wrinkles. Therefore, anti-oxidation has become an important part of eye skin care. Although traditional antioxidant ingredients, such as vitamin C and vitamin E, can remove free radicals to a certain extent, their stability and permeability still need to be improved, and it is difficult to meet the high requirements of modern eye skin care.

[0004] At the same time, the firmness and elasticity of the eye skin are also important indicators of its youthful state. As we age, the collagen and elastic fibers in the eye skin gradually decrease, causing the skin to sag and form obvious wrinkles. Therefore, firming and anti-wrinkle becomes another major challenge in eye skin care. Summary of the invention

[0005] In order to enhance the antioxidant, firming and anti-wrinkle effects, the present application provides a dual-antioxidant eye cream and a preparation method thereof.

[0006] In the first aspect, the present application provides a dual-antibiotic eye cream, which adopts the following technical solution: A double-antioxidant eye cream comprises the following components in terms of mass percentage: Component A1: 0.2-0.7% 4-hydroxyethylpiperazineethanesulfonic acid, 0.5-2% betaine, 2-6% dipropylene glycol, 0.01-0.2% allantoin, 0.005-0.05% chelating agent, water; A2 component: 0.3-0.8% ammonium acryloyldimethyltaurate / VP copolymer; Component B: 0.5-1.5% cetearyl wheat straw glycosides, 0.5-1.5% cetearyl alcohol, 0.5-1% glyceryl stearate, 0.5-1% PEG-100 stearate, 1-5% caprylic / capric triglyceride, 0.1-0.5% emblica fruit extract, 1-4% dimethicone, 0.05-0.5% tocopheryl acetate, 0.5-2% behenyl alcohol; Component C: 0.5-2% tranexamic acid; Component D: 0.1-2% whitening supplement; Component E: 0.1-3% antibacterial agent; F2 component: 0.05-0.25% Tricholoma matsutake extract.

[0007] By adopting the above technical solution, with the cooperation of cetearyl wheat straw glycosides, tranexamic acid, emblica extract and matsutake extract, a stable and lasting moisturizing barrier is formed on the surface of the eye skin. This barrier can effectively lock in moisture, prevent moisture loss, and ensure that the eye skin remains hydrated for a long time. At the same time, it can also enhance the skin's barrier function, resist the invasion of the external environment, and provide comprehensive protection for the eye skin.

[0008] Moreover, with the above combination, tranexamic acid, pine mushroom extract, and emblica extract can penetrate deeper into the eye skin and provide the necessary moisture and nutrients for skin cells. They can inhibit the activity of tyrosinase, effectively block the production and transfer of melanin, thus significantly reducing spots and dark circles, brightening the skin tone, promoting the regeneration and repair of skin cells, and enhancing the elasticity and firmness of the skin.

[0009] The combination of the above four not only forms a multiple moisturizing barrier to lock in moisture, but also accelerates the penetration of active ingredients into the deep layers of the eye skin. Through deep nourishment and repair, the cell vitality of the eye skin is significantly improved, fine lines and wrinkles are effectively reduced, and the skin becomes healthier and more elastic.

[0010] Preferably, according to the mass percentage of the double-antioxidant eye cream, the cetearyl wheat straw glycosides are 1.05%, the emblica fruit extract is 0.2%, the tranexamic acid is 1%, and the matsutake extract is 0.1897%.

[0011] By adopting the above technical scheme, the dosage coordination relationship of cetearyl alcohol straw glycosides, tranexamic acid, emblica extract, and matsutake extract in the system is further limited, so that the four can be more fully coordinated. It can form multiple moisturizing barriers on the surface of the eye skin, lock moisture, and prevent water loss, thereby keeping the eye skin moist for a long time. And it can accelerate the penetration into the deep layer of the eye skin, provide the skin with the required moisture and nutrients, promote the regeneration and repair of skin cells, and make the skin healthier and more elastic. Not only that, the coordination of the four can promote the ability of tranexamic acid and matsutake extract to inhibit the formation and transmission of melanin, further reduce spots and dark circles, and brighten the skin color. It can also enhance the repair and regeneration of eye skin, reduce fine lines and wrinkles, and make the eye skin more compact and elastic.

[0012] Preferably, according to the mass percentage of the double-antibiotic eye cream, the double-antibiotic eye cream also includes 0.05-0.15% carnosine and 0.01-0.03% ergothioneine.

[0013] By adopting the above technical solution, carnosine and ergothioneine work synergistically to target the key problem of skin aging - accumulation of free sugars, and show significant skin care effects.

[0014] As a natural antioxidant, carnosine has the ability to capture and remove free sugars in the body. This property helps reduce the non-enzymatic glycosylation reaction between free sugars and proteins, i.e. the glycation process, thereby reducing the damage to the skin structure caused by glycation, such as sagging and dullness. Through this mechanism, carnosine helps maintain the youthfulness and elasticity of the skin.

[0015] On the other hand, ergothioneine has multiple protective effects on the skin with its powerful antioxidant and anti-inflammatory properties. It can remove free radicals and reduce the negative effects of photodamage on the skin, while promoting the metabolism of skin cells and accelerating the synthesis of collagen and elastic fibers. This process not only helps to improve the firmness and elasticity of the skin, but also improves the skin tone and achieves the effect of removing yellowness and brightening.

[0016] When carnosine is used in combination with ergothioneine, the synergy between them is realized. The two work together on the skin, not only strengthening their respective skin care effects, but also forming a comprehensive antioxidant protection network. This network not only effectively resists external environmental damage to the skin, but also promotes the skin's self-repair and regeneration ability from the inside.

[0017] Preferably, according to the mass percentage of the dual-antioxidant eye cream, the B component also includes 1-4% avocado butter, 0.01-0.1% litchi seed extract, 0.01-0.1% rice extract, and 0.01-0.1% Atractylodes macrocephala root extract.

[0018] By adopting the above technical solution, avocado tree butter, litchi seed extract, rice extract, and Atractylodes macrocephala root extract are further added to provide antioxidant protection for the skin from the outside, while tocopherol acetate enhances the skin's antioxidant capacity from the inside. This dual antioxidant mechanism of endogenous and exogenous sources not only effectively removes free radicals, but also significantly improves skin dullness, delays the photoaging process, and brings a healthier and younger skin.

[0019] Preferably, according to the mass percentage of the dual-antibiotic eye cream, the F2 component also includes 0.5-3% of a polypeptide mixture.

[0020] Preferably, the polypeptide mixture includes acetyl hexapeptide-8, acetyl octapeptide-3, acetyl heptapeptide-4, palmitoyl tripeptide-5, and acetyl tetrapeptide-2.

[0021] Preferably, according to the mass percentage of the dual-antioxidant eye cream, the F2 component also includes 0.1-1% sodium hyaluronate mixture.

[0022] Preferably, the sodium hyaluronate mixture includes sodium hyaluronate, acetylated sodium hyaluronate, sodium hyaluronate cross-linked polymer, and hydrolyzed sodium hyaluronate.

[0023] By adopting the above technical solutions and further adding a variety of different peptides, their unique molecular structure can penetrate deep into the skin and tightly bind to skin cells, effectively promoting the regeneration of collagen. Collagen is a key component in maintaining skin elasticity and firmness. The improvement of its regeneration ability means that the skin around the eyes can be more full and elastic, thus significantly reducing the appearance of wrinkles, especially fine lines caused by changes in facial expressions.

[0024] The addition of sodium hyaluronate mixture provides long-lasting moisturizing and hydrating effects for the skin around the eyes. As an excellent moisturizing ingredient in nature, sodium hyaluronate can absorb and retain a large amount of water, creating a moist environment for skin cells. The design of four layers of sodium hyaluronate further enhances its moisturizing properties, ensuring that the skin around the eyes can be fully moisturized at different levels. This continuous moisturizing not only helps to improve the sagging of the skin around the eyes, but also makes the skin around the eyes more elastic and energetic. When peptides and quadruple sodium hyaluronate work together, they together build a comprehensive eye skin care system. Peptides are responsible for promoting collagen regeneration from the inside, filling the skin around the eyes and reducing the formation of wrinkles; while quadruple sodium hyaluronate provides long-lasting moisture and hydration to the eye skin from the outside, improving sagging and making the eye skin more elastic. This internal and external combination and dual action mechanism not only significantly improves the firmness and elasticity of the eye skin, but also brings it a healthier and younger state.

[0025] In a second aspect, the present application provides a method for preparing a dual-antibiotic eye cream, using the following technical solution: A method for preparing a dual-antibiotic eye cream comprises the following steps: Step 1: Homogenize and mix component A1, then add component A2 and mix evenly, then stir and mix at 85-88°C to obtain phase A; Step 2: Dissolve component B completely at 78-82°C to obtain phase B; Step 3: Mix phase A and phase B evenly, then add component C and continue mixing until uniform to obtain phase ABC; Step 4: Mixing phase ABC with phase D at 60-65° C. to obtain phase ABCD; Step 5: Cool down to 45-48°C, add the remaining raw materials to phase ABCD to obtain a dual-antibiotic eye cream.

[0026] In summary, this application has the following beneficial effects: It targets the three main causes of eye problems: skin oxidation, skin glycation, and inflammatory response. It uses multi-stage target action and multi-chain sniping to attack dark circles around the eyes, refine and lighten lines, and restore elasticity, smoothness, and brightness.

[0027] 1. Brighten the eye area and remove dark circles 1) Avocado tree butter, litchi seed extract, rice extract, Atractylodes macrocephala root extract, vitamin E, dual endogenous and exogenous antioxidants, effectively remove free radicals, improve dullness, and effectively delay photoaging.

[0028] 2) The combination of cetearyl straw glycosides, tranexamic acid, emblica extract and matsutake extract enhances the inhibition of tyrosinase activity, prevents the production and transfer of melanin, fades away melanin layer by layer, evens out the eye skin, and makes it vibrant and bright.

[0029] 3) The combination of carnosine and ergothioneine can effectively remove free sugars, accelerate the synthesis of skin collagen and elastic fibers, effectively slow down photodamage, remove yellowness and brighten the skin, resist sugar at the root, and build a protective shield for the skin.

[0030] 2. Multiple soothing effects to stabilize the eye area It uses a variety of plant extracts and reduces the use of irritating raw materials, thereby effectively soothing and anti-allergic, improving discomfort around the eyes, promoting self-repair of the eye skin, and showing young and healthy eyes.

[0031] 3. Tighten and lighten wrinkles, moisturize and brighten the eye area Specially added peptides can fight against expression lines, reduce the formation of wrinkles on the skin, effectively promote collagen regeneration, and fill the eye area; combined with 4 layers of sodium hyaluronate, it continuously moisturizes, improves sagging, and makes the eye area elastic.

[0032] 4. Promote absorption and penetration The combination of cetearyl straw glycosides, tranexamic acid, emblica extract and matsutake extract accelerates the penetration of active ingredients into the deep layers of the skin around the eyes. Through in-depth nourishment and repair, the cell vitality of the skin around the eyes is significantly improved, allowing for more complete absorption of active ingredients. DETAILED DESCRIPTION

[0078] Comparative Example 5 A dual-antioxidant eye cream is different from Example 2 in that cetearyl wheat straw glycosides, tranexamic acid, emblica fruit extract, and matsutake extract are omitted, and water is used to supplement the original content.

[0079] Performance testing 1. Antioxidant performance: DPPH free radical inhibition rate test Weigh 0.5 g of the double-antibiotic eye cream of Examples 1-4 and Comparative Examples 1-5, respectively, dissolve them in pure water, and transfer them to a 100 mL volumetric flask to make up to volume. Prepare a 5.00 × 10 -3 g / mL of sample solution.

[0080] Pipette 3 mL of the sample solution to be tested into a 10 mL volumetric flask, then add 3 mL of a 2×10 -4 g / mL DPPH solution. Cover the stopper, shake well, react for 30 minutes, and measure the absorbance A at 517nm i ; Determine the absorbance A of 3mL sample solution and 3mL ethanol mixture j ; The concentration of 3mL was determined to be 2×10 -4 The absorbance A0 after mixing 30 g / mL DPPH solution with 3mL pure water.

[0081] According to the formula P = [1-(A i -A j ) / A0]×100%, and the measured absorbance is substituted into the inhibitory rate of the test solution on DPPH· free radicals.

[0082] The inhibition rates are recorded in Table 2.

[0083] 2. Human body detection: 90 volunteers were selected and randomly divided into 9 groups, with 10 people in each group, and each group corresponded to a dual-antioxidant eye cream in Examples 1-4 and Comparative Examples 1-5.

[0084] The volunteers cleansed their faces with water before going to bed every night, and then applied a bean-sized amount of eye cream around their eyes for 28 days.

[0085] 1) Firming and anti-wrinkle testing: Before the test, use a skin elasticity meter to test the elasticity R2 value of the skin around the eyes; after 28 days of use, test the elasticity R2 value again.

[0086] The elasticity improvement rate was calculated according to (elasticity R2 value after use - elasticity R2 value before use) / elasticity R2 value before use * 100%. The average elasticity improvement rate of the volunteers in the same group was recorded in Table 2 as the group data.

[0087] 2) Moisture-replenishing and moisture-locking performance: Before the test begins, use a skin moisture tester to test the moisture content of the skin around the eyes. This is the initial moisture content.

[0088] 8 hours after applying eye cream for the first time, use a skin moisture tester to test the moisture content of the skin around the eyes again.

[0089] After using the eye cream for 28 days, use a skin moisture tester to test the moisture content of the skin around the eyes again.

[0090] The moisture content increase rate is calculated according to the formula (moisture content after use - initial moisture content) / moisture content after use * 100%.

[0091] The average value of the water content increase rate of the volunteers in the same group is taken as the data of this group and recorded in Table 2.

[0092] 3) Subjective feelings: Questionnaires were distributed to volunteers, including: (1) How quickly is the eye cream absorbed? The score is based on a scale of 0-5, with scores closer to 5 indicating faster absorption.

[0093] (2) Is the eye cream light? The score is 0-5, with the closer to 5, the lighter and less burdensome it is.

[0094] (3) Is the anti-wrinkle and firming effect of the eye cream significant? The score is based on a scale of 0-5, with the closer to 5 the more significant the anti-wrinkle and firming effect.

[0095] (4) Is the eye cream effective in brightening the eye area? The score is 0-5, with the closer to 5, the more obvious the eye area brightening effect.

[0096] The average scores of the volunteers in the same group are recorded in Table 2.

[0097] Table 2 Comparative Example 5 is based on Example 2, but cetostearyl alcohol straw glycosides, tranexamic acid, emblica extract, and matsutake extract are omitted. According to the test data in Table 2, the DPPH free radical inhibition effect of the double-resistance eye cream in Comparative Example 5 is obviously not as good as that of Example 2. In particular, the various data of human body detection have a very obvious downward trend compared with Example 2. It shows that after omitting cetostearyl alcohol straw glycosides, tranexamic acid, emblica extract, and matsutake extract, the system cannot play the special coordination effect of the four, so the obtained double-resistance eye cream is not effective.

[0098] Examples 1, 3 and 4 are based on Example 2, and raw materials such as carnosine, ergothioneine, and a polypeptide mixture are further added. The use of these raw materials further improves the performance of the double-resistant eye cream.

[0099] Comparative Examples 1-4 are based on the best Example 1, and any of the cetearyl alcohol straw glycosides, tranexamic acid, emblica extract, and matsutake extract are replaced with other raw materials. According to the test data in Table 2, whether it is the inhibition rate of DPPH free radicals or the various data of human body detection, Comparative Examples 1-4 cannot achieve the excellent effect of Example 1, especially in the water replenishment and water locking performance, firming and anti-wrinkle detection. The difference is more obvious. This is related to the fact that the combination of cetearyl alcohol straw glycosides, tranexamic acid, emblica extract, and matsutake extract can accelerate the penetration of active ingredients into the deep layers of the eye skin, deeply nourish and repair the skin around the eyes.

[0100] 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 modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
