Description

Technical Field

[0001] The present invention relates to the technical field of cosmetics, and in particular to an anti-wrinkle and firming composition and cosmetics. Background Art

[0002] As we age, skin aging problems gradually appear. As skin metabolism slows down, the collagen and elastic tissue fibers in the skin change, reducing their texture and content, causing the skin to gradually lose elasticity and become loose, resulting in wrinkles.

[0003] To meet the growing demand for anti-wrinkle products, numerous anti-wrinkle products are now available on the market. However, most existing anti-wrinkle products utilize a single active ingredient to achieve their anti-wrinkle effect. These single active ingredients have a low upper limit and cannot achieve the desired anti-wrinkle and firming effects. Furthermore, while there are also composite anti-wrinkle products on the market, the anti-wrinkle ingredients used in these products are mostly chemically synthesized, resulting in high irritation and poor safety.

[0004] In view of the above-mentioned related technologies, the inventors believe that natural extract ingredients are mild and not prone to allergies, and can be used as a direction for the development of anti-wrinkle compositions. To this end, the present invention provides an anti-wrinkle and firming composition comprising multiple natural extracts. Summary of the Invention

[0005] In order to overcome the technical defects of the prior art, the present invention provides an anti-wrinkle and firming composition and cosmetics. The anti-wrinkle and firming composition of the present invention is a mixture of multiple natural extracts, which not only has a mild effect but also has excellent anti-wrinkle and firming effects.

[0006] In a first aspect, the present application provides an anti-wrinkle and firming composition, which adopts the following technical solution: An anti-wrinkle and firming composition, comprising the following components in parts by weight: 0.1-2 parts of Acer tataricus fruit extract; 0.1-2 parts of yarrow extract; 0.1-2 parts of Malva sylvestris extract; 0.1-2 parts of sage leaf extract.

[0007] By adopting the above-mentioned technical solution, the present application scientifically combines four plant extracts of Malvaceae fruit, Yarrow, Malva sylvestris, and Sage leaf, and utilizes the synergistic mechanism of each ingredient to significantly enhance the overall anti-wrinkle and firming effect of the composition. Moreover, the natural extracts have little irritation to the skin, ensuring the safety and mildness of the product.

[0008] Preferably, the following components are included in parts by weight: 0.5-1.5 parts of Acer tataricus fruit extract; Yarrow extract 0.5-1.5 parts; 0.5-1.5 parts of Malva sylvestris extract; 0.5-1.5 parts of sage leaf extract.

[0009] By adopting the above technical solution, the present application further limits the ratio of the four plant extracts, so that the synergistic effect of the four plant extracts can be more fully exerted, forming a better superposition effect, and further enhancing the anti-wrinkle and firming performance of the composition.

[0010] In a second aspect, the present application provides a cosmetic comprising an anti-wrinkle and firming composition, wherein the weight fraction of the anti-wrinkle and firming composition in the cosmetic is 0.1-10% by weight.

[0011] By adopting the above technical solution, this application accurately controls the content of active ingredients within 0.1-10%. This concentration range takes into account both efficacy and safety, avoiding both poor effects caused by too low ingredient concentration and potential irritation risks caused by too high concentration, thus achieving a balance between efficient skin care and safe use.

[0012] Preferably, the cosmetic further comprises 90%-99.9% of a cosmetic auxiliary material matrix.

[0013] By adopting the above technical solution, the present application uses the cosmetic excipient matrix as a stable carrier of the active ingredient, ensuring the uniform dispersion and slow release of the anti-wrinkle and firming composition, while optimizing the product texture, skin feel and usage experience.

[0014] Preferably, the cosmetic auxiliary material matrix is selected from one or more of moisturizers, emollients, thickeners, emulsifiers, antioxidants, preservatives, and flavors.

[0015] By adopting the above technical solution, the moisturizers and emollients used in this application synergistically enhance the skin's hydration, the thickeners and emulsifiers ensure the stability of the product texture, the antioxidants extend the shelf life of the active ingredients, the preservatives ensure product safety, and the flavors impart a pleasant aroma, which can meet the needs of different customers.

[0016] Preferably, the moisturizing agent is one or more of glycerol, methylserine, sodium polyaspartate, and sodium hyaluronate; The emollient is one or more of caprylic / capric triglyceride, shea butter, dimethicone, and jojoba seed oil; The thickener is one or more of cetearyl alcohol, ammonium acryloyldimethyltaurate / VP copolymer, and xanthan gum.

[0017] By adopting the above technical solution, this application selects moisturizers such as glycerin, methylserine, sodium polyaspartate, sodium hyaluronate, etc., which can quickly penetrate the skin and build a long-lasting moisture-locking barrier; selects emollients such as caprylic / capric triglyceride, shea butter esters, polydimethylsiloxane, jojoba seed oil, etc., which can deeply nourish the skin and enhance the soft and smooth touch; selects cetearyl alcohol, ammonium acryloyldimethyltaurate / VP copolymer, xanthan gum and other thickeners to precisely control the product texture to ensure uniform extension when applied.

[0018] In a third aspect, the present application also includes the use of the anti-wrinkle and firming composition in the preparation of cosmetics.

[0019] Preferably, the cosmetics can be selected from cleansing milk, cleansing cream, toner, lotion, emulsion, cream, essence, facial mask, eye cream, eye mask and body lotion.

[0020] By adopting the above-mentioned technical solution, the anti-wrinkle and firming composition of the present application can be used to develop multiple categories of cosmetics such as facial cleansers, toners, essences, etc., covering the entire process of skin care scenarios such as cleansing, conditioning, and care, and can effectively meet diversified anti-wrinkle and firming needs, showing good application potential.

[0021] In summary, this application has the following beneficial effects: 1. This application adopts a scientific ratio of multiple plant extracts to work synergistically, significantly improving the anti-wrinkle and firming effect of the composition, avoiding the efficacy limitations of a single ingredient, and the natural extracts themselves have little irritation to the skin, ensuring the safety and mildness of the product.

[0022] 2. This application further expands the application adaptability of the anti-wrinkle and firming composition in different types of cosmetics by rationally blending plant extracts and cosmetic excipient matrices and by using diversified cosmetic excipient matrices. DETAILED DESCRIPTION

[0023] In order to more fully understand the technical content of the present invention, the present invention will be further introduced and illustrated in conjunction with specific embodiments below.

[0024] The raw materials used in the embodiment are all conventional commercially available products.

[0025] The main raw materials involved in the implementation are as follows: Tigertail extract is a natural substance extracted from the Tigertail fruit. It can activate signal pathways, prompting fibroblasts to synthesize and secrete more type I collagen and elastin, increasing skin fullness and elasticity, and reducing wrinkles; at the same time, it inhibits the activity of enzymes that degrade collagen, reduces its decomposition, maintains and increases the skin's collagen content, and achieves anti-wrinkle effects.

[0026] Yarrow extract is a natural substance extracted from yarrow. It is rich in active ingredients such as flavonoids and phenols. It can reduce inflammatory damage by inhibiting the release of inflammatory mediators such as histamine, regulating immune responses and scavenging free radicals.

[0027] Mallow extract is a natural substance extracted from Mallow. It can activate cell proliferation-related signal pathways, promote the regeneration of epidermal cells and dermal cells, stimulate the synthesis of collagen and elastic fibers, and enhance the extracellular matrix structure.

[0028] Sage leaf extract is a natural substance extracted from sage leaves. It can inhibit the activity of sebaceous gland cell-related enzymes, reduce the stimulation of androgens on sebaceous glands, and reduce oil synthesis and secretion; it can also balance the skin flora and help the skin regulate oil levels.

[0029] Based on this, the present invention provides an anti-wrinkle and firming composition, which is obtained by mixing multiple natural extracts to obtain a composition with excellent anti-wrinkle and firming effects. The specific technical solution is as follows: An anti-wrinkle and firming composition, comprising the following components in parts by weight: 0.1-2 parts of Acer tataricus fruit extract; 0.1-2 parts of yarrow extract; 0.1-2 parts of Malva sylvestris extract; 0.1-2 parts of sage leaf extract.

[0030] Preferably, the following components are included in parts by weight: 0.5-1.5 parts of Acer tataricus fruit extract; Yarrow extract 0.5-1.5 parts; 0.5-1.5 parts of Malva sylvestris extract; 0.5-1.5 parts of sage leaf extract.

[0031] The anti-wrinkle and firming compositions of Examples 1 to 4 were prepared according to the formulations in Table 1 below.

[0032] Table 1 Formula of the anti-wrinkle and firming composition of Examples 1-4 In order to further verify the performance of the anti-wrinkle and firming composition of the present invention, the following comparative examples were prepared based on the formula of the anti-wrinkle and firming composition of Example 1: Comparative Example 1 The formula of the anti-wrinkle and firming composition of Comparative Example 1 is substantially the same as that of the anti-wrinkle and firming composition of Example 1, except that 0.1 parts by weight of Centella asiatica extract is used instead of the Malpighia ovata fruit extract.

[0033] Comparative Example 2 The formula of the anti-wrinkle and firming composition of Comparative Example 2 is substantially the same as that of the anti-wrinkle and firming composition of Example 1, except that 0.1 parts by weight of elderflower extract is used to replace the yarrow extract.

[0034] Comparative Example 3 The formula of the anti-wrinkle and firming composition of Comparative Example 3 is substantially the same as that of the anti-wrinkle and firming composition of Example 1, except that 0.1 parts by weight of marshmallow root extract is used instead of mallow extract.

[0035] Comparative Example 4 The formula of the anti-wrinkle and firming composition of Comparative Example 4 is substantially the same as that of the anti-wrinkle and firming composition of Example 1, except that 0.1 parts by weight of common sage leaf extract is used instead of the medicinal sage leaf extract.

[0036] Among them, Centella asiatica extract contains ingredients such as asiatica glycoside, which can promote the synthesis of collagen-related substances, inhibit collagenase, repair the barrier and have strong anti-inflammatory effects, relieve redness and sensitivity, and have strong antioxidant capacity. Its function is similar to that of the extract of Malpighia ovata.

[0037] Western elderberry flower extract is rich in antioxidants such as anthocyanins, which can neutralize free radicals, regulate immunity, inhibit histamine release, and gently soothe sensitive skin. Its function is similar to that of yarrow extract.

[0038] Marshmallow root extract contains mucopolysaccharides, which can effectively moisturize and lock in moisture, repair mucous membrane tissue, and give the product a silky skin feel. Its function is similar to that of marjoram extract.

[0039] Ordinary sage leaf extract contains volatile oil, which has basic anti-inflammatory, antibacterial, astringent and oil-control capabilities, and its functions are similar to those of medicinal sage leaf extract.

[0040] Performance Testing 1. Human skin patch test Refer to the human skin patch test in the 2022 edition of the "Safety Technical Specifications for Cosmetics" to test whether the above-mentioned example compositions cause skin irritation or allergic reactions. The specific experimental steps are as follows: (1) 120 individuals aged 18-60 years were selected and divided into four groups, with 15 men and 15 women in each group, all without severe skin diseases, allergies or immune diseases; (2) The selected area shall not exceed 50mm 2Qualified patch test equipment with a depth of approximately 1mm was used. 0.02 mL of the anti-wrinkle and firming composition of Examples 1-4 was placed into the patch test chamber. The control well served as a blank control (no substance was placed). The patch test chamber containing the finished product was applied to the healthy skin on both sides of the spine on the back of the subject using hypoallergenic tape. Gently press the patch evenly with the palm of your hand for 24 hours. Skin reactions were observed 30 minutes after removal of the finished product (after the indentation disappeared), 24 hours, and 48 hours later. The results were recorded. The reaction results are shown in Table 2 below, and the specific reaction results criteria are shown in Table 3 below.

[0041] Table 2 Human skin patch test results serial number 30min 24h 48h Example 1 Level 0, 30 people Level 0, 30 people Level 0, 30 people Example 2 Level 0, 30 people Level 0, 30 people Level 0, 30 people Example 3 Level 0, 30 people Level 0, 30 people Level 0, 30 people Example 4 Level 0, 30 people Level 0, 30 people Level 0, 30 people Table 3 Specific standards for reaction results Table 2 shows that all subjects experienced a grade 0 reaction, indicating no allergic reaction. This indicates that the anti-wrinkle and firming composition of the present invention is mildly irritating to the skin and has a good safety profile.

[0042] 2. Anti-wrinkle and firming test Elastase has the ability to degrade various proteins, including collagen and elastin. Changes in elastin structure during skin aging are a major cause of wrinkles and sagging. Studies have shown that inhibiting elastase from breaking down elastin can have firming and anti-wrinkle effects. Therefore, the elastase inhibition rate can be used to determine whether a test sample possesses anti-wrinkle and firming properties.

[0043] The specific experimental steps of the anti-wrinkle and firming test are as follows: (1) Prepare 10 mL of 25% concentration sample solution of the anti-wrinkle and firming compositions of Examples 1-4 and the anti-wrinkle and firming compositions of Comparative Examples 1-4, respectively.

[0044] (2) Take nine clean test tubes and label them as a blank control group and a sample solution group. The test tubes for the sample solution groups are labeled according to the names of Examples 1-4 and Comparative Examples 1-4, respectively. Add 2 mL of deionized water to the blank control test tube, and then take 2 mL of the sample solution and place it in the corresponding test tube for the sample solution group. Subsequently, add 20 mg of orcein elastin to each test tube, followed by 3 mL of borate buffer solution with a pH value of 8.8.

[0045] (3) Place each test tube in a 37°C water bath and shake at constant temperature for 10 minutes. After shaking, add 2 mL of 0.2 mg / mL elastase solution to each test tube.

[0046] (4) Finally, the absorbance of each tube was measured at a wavelength of 495 nm, and the elastase inhibition rate was calculated based on the absorbance.

[0047] The above test results are shown in Table 4 below: Table 4 Elastase inhibition rate results As shown in Table 5, the anti-wrinkle and firming compositions of Examples 1-4 of the present invention exhibited elastase inhibition rates ranging from 72.1% to 90.1%, demonstrating that the various components synergistically construct a three-dimensional anti-wrinkle and firming chain, effectively inhibiting elastase with significant differences. When the anti-wrinkle and firming composition of Example 1 was added at a dosage of 0.1% (sample concentration of 25%), the elastase inhibition rate reached 72.1%, demonstrating that the anti-wrinkle and firming composition of the present invention exhibits excellent anti-wrinkle and firming effects even at relatively low dosages. Furthermore, the elastase inhibition rates of the anti-wrinkle and firming compositions of Comparative Examples 1-4, which replaced the anti-wrinkle and firming composition of Example 1 with the same substance, were all lower than those of the anti-wrinkle and firming composition of Example 1. This demonstrates that the present invention achieves synergistic efficacies through a specific combination of ingredients, making the functions of each ingredient difficult to replace.

[0048] The present invention also provides a facial cream with anti-wrinkle and firming effects, comprising the anti-wrinkle and firming composition and a cream base. The cream base comprises water, a moisturizer, an emollient, a thickener, an emulsifier, an antioxidant, a preservative, and a fragrance, and the anti-wrinkle and firming composition accounts for 0.1-10% by weight of the facial cream.

[0049] The present invention also provides a formula of the above-mentioned facial cream, and the specific composition of the formula is shown in Table 4 below.

[0050] Table 4 Cream formula The preparation method of the above-mentioned facial cream is specifically as follows: S1: Add water, glycerin, methylserine, xanthan gum, and sodium hyaluronate to a mixing bowl. Turn on the heat and stir. Raise the temperature to 70-75°C. Continue stirring until all ingredients are completely dissolved. The xanthan gum can be pre-mixed with the glycerin to prevent clumping and ensure a better dispersion.

[0051] S2: Add caprylic / capric triglyceride, shea butter esters, dimethicone, cetearyl alcohol, cetearyl glucoside, jojoba seed oil, and tocopheryl acetate to the oil phase pot. Heat to 70-75°C and stir thoroughly to completely melt and mix the ingredients. Then, pump the oil phase into the main emulsifier and continue stirring for 15 minutes. Then, start high-speed homogenization at 3000 rpm for 5 minutes to form a uniform and stable emulsion.

[0052] S3: Add ammonium acryloyldimethyltaurate / VP copolymer, maintain the temperature, and continue stirring for 15 minutes to fully disperse the thickener and improve the viscosity and stability of the product.

[0053] S4: Turn on the cooling water to stir and cool down. When the temperature drops below 50 degrees, add the essence, sodium polyaspartate, Malvaceae fruit extract, Yarrow extract, Mallow extract, and Salvia officinalis leaf extract in turn and stir evenly to ensure that the active ingredients are fully integrated into the system while avoiding high temperature from destroying the activity of the ingredients.

[0054] S5: Continue stirring and cooling until the product temperature drops to the appropriate range and passes the quality inspection before it can be discharged and packaged.
