Description

Technical Field

[0001] This invention belongs to the field of cosmetic technology, and specifically relates to an anti-aging composition, its preparation method, and its application. Background Technology

[0002] As we age, our skin exhibits signs of aging, including fine lines and sagging. This is due to a decrease in collagen and elastin in the skin, as well as damage from free radicals. With these early signs of aging becoming increasingly apparent, effectively combating early signs of aging has become a key research focus in the skincare industry. Currently, most anti-aging products on the market primarily target the repair of existing deep wrinkles, and most only use a single ingredient to achieve a short-term reduction in wrinkles. Skincare products that address the overall improvement of skin condition are relatively few, or their effectiveness is poor, or they contain too many ingredients, resulting in an oily feel or even significant irritation, thus limiting their effectiveness in combating early signs of aging.

[0003] Therefore, it is essential to develop a gentle, non-irritating, non-greasy product that can effectively combat early signs of aging. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention provides an anti-aging composition, its preparation method, and its application. This anti-aging composition is mild, non-irritating, and non-greasy, and has antioxidant, firming, and anti-wrinkle effects, achieving an effective anti-aging effect.

[0005] The first aspect of the present invention provides an anti-aging composition comprising the following components: oat kernel oil, grape seed oil, avocado oil, camellia seed oil, and chrysanthemum extract.

[0006] Specifically, the effects of each component in the anti-aging composition of the present invention are as follows:

[0007] Grape seed oil contains linoleic acid, which helps maintain the skin barrier and channel function. It is easily absorbed by the skin, deeply nourishes and conditions skin cells, and has a free radical scavenging effect. It promotes appropriate cross-linking of collagen, preventing wrinkles and vesicles. Additionally, grape seed oil contains approximately 360.20 μg / g of vitamin E, which accelerates the removal of damaged and aging cells, thus delaying aging. Grape seed oil is rich in vitamins, minerals, and flavanols (proanthocyanidins), which help strengthen collagen and elastin, the connective tissue that makes up the skin and joints. Grape seed oil has a particularly high Omega-6 linoleic acid content (approximately 76%), resulting in a light texture that easily penetrates deep into the skin. Grape seed oil has conditioning and astringent properties, helping to condition the skin. When applied directly to the skin, grape seed oil is easily absorbed. Grape seed oil can also accelerate skin metabolism, speed up skin renewal, protect epidermal cells and new cells, protect skin moisture, and has a certain moisturizing effect.

[0008] Camellia seed oil is rich in monounsaturated oleic acid (approximately 80%). It won't clog pores or feel greasy due to its tannin content. As an astringent plant oil, it's more suitable for oily or problem skin than other oils rich in oleic acid. Its slightly dry and cooling nature helps prevent skin aging. Camellia seed oil has moisturizing and skin-softening effects; coupled with protective plant polyphenols, vitamins A, B, C, and E, and other antioxidants, it helps protect against UV rays, environmental damage, and free radical scavenging. It's also easily absorbed by the skin, and its plant-based squalene content nourishes and maintains healthy skin.

[0009] Avocado oil contains approximately 20% unsaturated linoleic acid and about 12% rare palmitic acid, which nourishes the skin and maintains a healthy stratum corneum. It is also rich in vitamins A, B, and E, as well as proteins and amino acids, and trace amounts of lecithin. Avocado oil promotes collagen production in the dermis (middle layer of the skin). Its phytosterols help maintain collagen and skin structure, prevent age spots and weakened cell walls, soothe inflammation, promote tissue regeneration, and maintain the skin's barrier function. Avocado oil is one of the few plant oils rich in carotenoids, providing natural protection against UV damage.

[0010] Oat kernel oil contains a balanced ratio of oleic acid and linoleic acid, approximately 40% each, which is particularly beneficial for the skin's stratum corneum. Palmitic acid, a short-chain fatty acid, can soothe and protect the outer layer of skin. Oat kernel oil is also rich in vitamin E, antioxidants, and carotenoids. It contains over 20 unique polyphenols that can fight inflammation, reduce proliferation, and relieve itching. Notably, it contains avenanthramide, a powerful antioxidant that can defend against fungal invasion. Oat kernel oil is also rich in beta-glucan, a polysaccharide, soluble fiber, and phospholipids.

[0011] Globe amaranth extract is rich in alkylamides and is considered a natural alternative to botulinum toxin. It improves dermal structure and firms the skin by stimulating fibroblast activity, and can treat dermatitis, enhance capillary resistance, eliminate free radicals, and provide antioxidant effects to alleviate aging. It also has a certain inhibitory effect on melanocytes. In summary, globe amaranth extract improves dermal structure, firms the skin, treats dermatitis, enhances capillary resistance, eliminates free radicals, and alleviates aging.

[0012] This invention utilizes a combination of several specific plant oils and extracts to create a composition that complements the lipids secreted by the skin itself, replenishing the skin's lack of oils. Simultaneously, the plant oils contain antioxidants, providing natural nutritional sunscreens to maintain the healthy function of skin cells. The components in this composition exert a synergistic effect, promoting appropriate cross-linking of collagen from multiple angles and in all aspects, preventing wrinkles and vesicles from forming on the skin, accelerating the removal of damaged and aging cells, and exhibiting antioxidant, firming, and anti-wrinkle effects, thereby effectively combating early signs of aging.

[0013] According to some embodiments of the present invention, the anti-aging composition comprises the following components: 1-20 parts of oat kernel oil, 1-50 parts of grape seed oil, 1-50 parts of avocado oil, 1-50 parts of camellia seed oil, and 0.01-2 parts of chrysanthemum extract.

[0014] According to some embodiments of the present invention, the anti-aging composition comprises, by weight parts: 5-20 parts oat kernel oil, 5-50 parts grape seed oil, 5-50 parts avocado oil, 5-50 parts camellia seed oil, and 0.5-2 parts chrysanthemum extract.

[0016] A second aspect of the present invention provides a method for preparing the anti-aging composition of the present invention, comprising the following steps:

[0017] The oat kernel oil, grape seed oil, avocado oil, camellia seed oil, and chrysanthemum extract are mixed to obtain the anti-aging composition.

[0018] A third aspect of the present invention provides a cosmetic product comprising the anti-aging composition described herein.

[0019] According to some embodiments of the present invention, the composition is added to the cosmetic in an amount of 5-50 wt%.

[0020] According to some embodiments of the present invention, the composition is added to the cosmetic in an amount of 10-30 wt%.

[0021] According to some embodiments of the present invention, the dosage form of the cosmetic is selected from creams, lotions, aqueous solutions, gels, or sheet masks.

[0022] A fourth aspect of the present invention provides an essential oil comprising the anti-aging composition described herein.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] This invention rationally combines oat kernel oil, grape seed oil, avocado oil, camellia seed oil, and chrysanthemum extract. The components work synergistically to produce a gentle, non-irritating, and non-greasy product that is easily absorbed by the skin. It has antioxidant, firming, and anti-wrinkle effects, thus effectively combating early signs of aging. Detailed Implementation

[0171] Experimental Example 2: Determination of Superoxide Anion Radical Scavenging Capacity

[0172] Test samples: Anti-aging compositions of Examples 1-11 and Comparative Examples 1-15.

[0173] The specific measurement method is as follows:

[0174] Take 4.5 mL of 0.05 mol / L Tris-HCl buffer (pH 8.2) and preheat it in a 25°C water bath for 20 min. Add 1 mL of the test sample, followed by 0.4 mL of 25 mmol / L pyrogallol solution (preheated in a 25°C water bath for 20 min). Mix well and react in a 25°C water bath for 5 min. Terminate the reaction by adding 1.0 mL of 8 mol / L hydrochloric acid. Measure the absorbance at 299 nm using the Tris-HCl buffer as a reference.

[0175] Blank control experiment: Replace the test sample with only 1 mL of ethanol, and keep other steps unchanged. Calculate the clearance rate (D) according to formula (1).

[0176] D(%)=[1-(A2 / A1)]×100% Equation (1);

[0177] 1) In the formula, A1 is the absorbance value of the blank control; A2 is the absorbance value of the test sample after testing.

[0185] Experimental Methods: 310 participants (aged 30-45) with wrinkles around the eyes were selected as volunteers for the firming and anti-wrinkle efficacy test (10 volunteers used the same sample). Participants applied the product to the skin around their eyes twice daily, morning and evening. On day 0, day 7 (D7), and day 14 (D14), under conditions of 21±1℃ and 50±10% humidity, facial elasticity (R²) was measured after cleansing the face and waiting 20 minutes. The overall effect of the product on skin firming was evaluated.

[0186] Testing instrument: MPA580 skin elasticity tester (manufactured by CK GmbH, Germany).

[0187] The firming effect of a product is evaluated by measuring the skin elasticity R² value, which is the rate of change in skin elasticity after product use compared to before use. A positive value indicates an increase in the ratio of maximum skin stretch displacement, indicating better skin elasticity, while a negative value indicates a decrease in the ratio of maximum skin stretch displacement, indicating poorer skin elasticity.

[0188] Result determination: If the change in the instrument test parameter (elasticity R2 value) at any viewing point after product use is improved compared to before use, the product is considered to have a firming effect; otherwise, the product is considered not to have a firming effect. The test results are shown in Table 6.

[0192]

[0193] As shown in Table 6, the essential oils in Application Examples 1-15 all have firming effects. However, the content of the anti-aging composition in Application Example 4 is too low (less than 5%), which reduces the effect. The content of the anti-aging composition in Application Example 5 is too high (greater than 50%), resulting in a lower R2 change rate. It also tends to make the cosmetics too oily, resulting in a poor user experience, difficulty in absorbing nutrients, and potential clogging of pores, thus affecting the cosmetics' effectiveness. Using only a single component (Application Examples 2-6), or a composition lacking any one component (Application Examples 7-11), or replacing the components in the anti-aging composition of the present invention with other components with similar effects (Application Examples 12-16) cannot achieve the effects of Application Examples 1-15.

[0194] Experiment 4: Anti-wrinkle efficacy test on human body

[0195] Test substances: essential oils from Examples 1-15 and Comparative Examples 1-16.

[0196] Test Method: 310 participants (aged 30-45) with wrinkles around the eyes were selected as volunteers for the firming and anti-wrinkle efficacy test (10 volunteers used the same sample) (same as volunteers in Experiment 3). Participants applied the product to the eye area twice a day, morning and evening. On day 0, day 7 (D7), and day 14 (D14), under conditions of 21±1℃ and 50±10% humidity, participants cleansed their faces and waited 20 minutes before taking photos of their faces using a VISIA 7. The number of wrinkles around the eyes, the total area of ​​wrinkles, the average length of wrinkles, and the percentage of wrinkle area were measured to evaluate the anti-wrinkle efficacy of the product.

[0197] Average wrinkle length change rate: This refers to the rate of change in the average length of wrinkles around the eyes after product use compared to before use. A positive value indicates an increase in the average length of wrinkles around the eyes, meaning the wrinkles are longer; a negative value indicates a decrease in the average length of wrinkles around the eyes, meaning the wrinkles are shorter.

[0198] Wrinkle count change rate: This refers to the rate of change in the number of wrinkles around the eyes after product use compared to before use. A positive value indicates an increase in the number of wrinkles around the eyes, meaning there are more wrinkles around the eyes; a negative value indicates a decrease in the number of wrinkles around the eyes, meaning there are fewer wrinkles around the eyes.

[0199] Change rate of total wrinkle area: This refers to the rate of change in the total area of ​​wrinkles around the eyes after product use compared to before use. A positive value indicates an increase in the total area of ​​wrinkles around the eyes, meaning more wrinkles are present; a negative value indicates a decrease in the total area of ​​wrinkles around the eyes, meaning fewer wrinkles are present.

[0200] Change rate of wrinkle area percentage: This refers to the rate of change in the percentage of wrinkles around the eyes after product use compared to before use. A positive value indicates an increase in the percentage of wrinkles around the eyes, meaning more wrinkles; a negative value indicates a decrease in the percentage of wrinkles around the eyes, meaning fewer wrinkles.

[0201] The test results are shown in Table 7.

[0213] As shown in Table 7, the essential oils in Application Examples 1-15 all have anti-wrinkle capabilities. However, the content of the anti-aging composition in Application Example 4 is too low (less than 5%), resulting in reduced effectiveness. The content of the anti-aging composition in Application Example 5 is too high (greater than 50%). Although the number of wrinkles around the eyes, total wrinkle area, average wrinkle length, and wrinkle area percentage decreased in the first 7 days, these values ​​actually increased after 14 days compared to the 7-day data. This fails to achieve the desired effect and can easily lead to excessively oily cosmetics, poor user experience, and difficulty in absorbing nutrients. It may also clog pores and affect the effectiveness of the cosmetics. Using only a single component (Application Examples 2-6), or a composition lacking any component (Application Examples 7-11), or replacing the components in the anti-aging composition of this invention with other components of similar efficacy (Application Examples 12-16) cannot achieve the effects of Application Examples 1-15.

[0214] Based on the above experimental results, by adjusting the ratio of each component in the anti-aging composition of the present invention and adjusting the mass percentage of the anti-aging composition of the present invention in cosmetics, a more superior anti-aging effect can be obtained.

[0215] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
