Description

Technical Field

[0001] The present application relates to the field of cosmetic technology, and in particular to an anti-aging essence lotion and a preparation method thereof. Background Art

[0002] As we age, we are aging. To meet the pursuit of beauty, anti-aging skin care products are emerging in an endless stream. The anti-aging methods of common anti-aging skin care products on the market mainly include the following aspects: (1) Improving cell antioxidant capacity: by adding antioxidants, it helps to remove free radicals, reduce oxidative damage to cell membranes and nucleic acids, and protect the skin from oxidative stress caused by environmental pollution and ultraviolet radiation, thereby slowing down the aging process of the skin. (2) Repairing DNA damage: using active ingredients such as coenzyme Q10 and polyphenol compounds to reduce DNA damage caused by external factors, maintain the integrity of cell genetic information, reduce the risk of disease, and indirectly delay aging. (3) Promoting epidermal cell renewal: active ingredients activate the signal pathways triggered by keratinocytes, such as hyaluronic acid absorbing and locking in moisture, stimulating epidermal cell division and proliferation, accelerating metabolism, and promoting epidermal cell renewal. (4) Regulating immune response: using active ingredients with immunomodulatory effects to balance the body's immune response, enhance the skin's own defense ability, resist the invasion of external pathogens, and slow down aging. (5) Improve the stability of the skin microenvironment: Optimize the local pH value and water content of the skin through a variety of active ingredients, create a microenvironment that is conducive to skin self-repair, help resist external stimuli, and slow down the aging process.

[0003] Cosmetics are not the same as medicines. The premise for the active substances in cosmetics to work is that they need to be absorbed through the skin and enter different skin layers such as the epidermis or dermis to work. However, most of the more effective anti-aging active substances on the market are water-soluble macromolecular active substances. In addition, the existence of the main transdermal permeation barrier, the stratum corneum, makes the proportion of active substances that can be absorbed through the skin and work very small. In order to achieve the ideal effect, the content of active substances must be increased. However, increasing the content of active substances will lead to a significant increase in product costs, a decrease in cost-effectiveness, and it is difficult to meet the requirements of consumers.

[0028] The features and exemplary embodiments of various aspects of the application will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the application. However, it is obvious to those skilled in the art that the application can be implemented when some details in these specific details are not needed. The following description of the embodiment is only to provide a better understanding of the application by illustrating the example of the application. In the following description, at least part of the known technology is not shown, so as to avoid causing unnecessary ambiguity to the application. In addition, the features, structures or characteristics described hereinafter may be combined in one or more embodiments in any suitable manner.

[0029] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish an entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. In the description of the present application, it should be noted that, unless otherwise specified, the meaning of "multiple" is more than two. Moreover, the term "include", "comprise" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only include those elements, but also include other elements not clearly listed, or also include elements inherent to such process, method, article or equipment. In the absence of more restrictions, the elements limited by the sentence "include..." do not exclude the existence of other identical elements in the process, method, article or equipment including the elements.

[0030] Fruit acid can weaken the adhesion between keratinocytes by interfering with the binding force of the cell surface through iron atoms, activate steroid sulfatase and serine protease to degrade desmosomes, regulate the connection of keratinocyte desmosomes, achieve special effects and instant gentle exfoliation, and thus increase the transdermal absorption of active substances. It can also act on the dermis to increase the synthesis of glycosaminoglycans in the dermis, thereby promoting the synthesis of new collagen in the dermal papillary layer, and can also regulate the degradation of the mechanism and collagen production by stimulating keratinocytes to release cytokines. In other words, fruit acid can not only enhance the absorption of the original active substances, but also has anti-aging effects. However, there are few studies on the direct application of fruit acid to resident skin care products, and the fruit acid system is not good at thickening, so it is difficult to make a product that is both stable and has a good skin feel.

[0031] In view of this, the present application provides an anti-aging essence lotion, which can effectively have good anti-aging efficacy and mildness and enhance the penetration of the original anti-aging active components by selecting fruit acids of different molecular weights for compounding.

[0032] [Anti-aging Essence]

[0033] The embodiment of the first aspect of the present application provides an anti-aging essence lotion, comprising the following components in weight percentage: 0.5-6 parts of emulsifier, 0.5%-15% of oil phase component, 0.05%-2% of water-soluble polymer, 47%-80% of aqueous phase component, 0.05%-20% of fruit acid compound, and 0.05%-10% of anti-aging active component; wherein the fruit acid compound comprises macromolecular fruit acid and small molecular fruit acid, the molecular weight of the macromolecular fruit acid can be greater than or equal to 178, and the molecular weight of the small molecular fruit acid can be less than or equal to 100.

[0034] In the present application, based on the respective characteristics of different molecular size fruit acids, small molecule fruit acid and macromolecular fruit acid are used to compound a fruit acid compound, wherein the permeability of small molecule fruit acid is strong, it is easy to penetrate the stratum corneum and does not destroy the epidermal barrier function, it takes effect quickly, and side effects such as post-inflammatory pigmentation will not occur; macromolecular fruit acid mildness is extremely high, and has good moisturizing, anti-aging, and firming effects, and can play a deep anti-aging effect, based on this, macromolecular fruit acid and small molecule fruit acid are compounded and used, and it is added to cosmetics so that the adhesion of keratinocytes to each other can be effectively weakened, and the special effect is gently peeled off, so that the penetration of anti-aging active components can be increased, and then the anti-aging effect is enhanced. At the same time, fruit acid itself can increase the synthesis of glycosaminoglycans in the dermis, and then promote the synthesis of new collagen in the papillary layer of the dermis, and through multiple synergistic enhancement, an effective anti-aging effect is played.

[0035] In the embodiment of the present application, by optimizing the oil phase components, water-soluble polymers and emulsifiers in the anti-aging essence milk, and coordinating with the fruit acid compound, the mildness, moisturizing, spreadability and texture of the product can be effectively improved, and the consumers' requirements for refreshing and moisturizing skin feel and non-sticky using acid-containing products can be met. At the same time, the phospholipid bilayer structure of this anti-aging essence milk close to the skin can further enhance the efficient penetration of the functional ingredients. In addition, the pH value of the product in the above-mentioned composition can be controlled at more than 4, and its effect is mild and non-irritating, and it is used as a resident product to prolong the action time of the active ingredient and give full play to the anti-aging effect.

[0036] In some embodiments, based on the total amount of the fruit acid compound, the mass content of the macromolecular fruit acid may be 76%-97%, and the mass content of the small molecule fruit acid may be 3%-14%.

[0037] Optionally, based on the total amount of the fruit acid compound, the mass content of the macromolecular fruit acid may be 80%-97%, and the mass content of the small molecular fruit acid may be 3%-10%.

[0038] In the fruit acid compound of the anti-aging essence provided in the embodiment of the present application, the macromolecular fruit acid plays a major role in anti-aging and moisturizing, and the small molecule fruit acid plays a highly efficient penetration role.

At the same time, the fruit acid compound with the above ratio can further promote the penetration and retention of anti-aging active components, further improving the anti-aging effect.

[0039] In some embodiments, the small molecule fruit acid may include one or more of glycolic acid and lactic acid.

[0044] Research has found that by using glycolic acid as a small molecule fruit acid and gluconolactone and lactobionic acid as a large molecule fruit acid, and by controlling the ratio of the three within the above range, the fruit acid compound can have better penetration and anti-aging effects, and at the same time can well promote the efficacy of the anti-aging active components.

[0045] In some embodiments, the anti-aging active component may include one or more of bispyribonucleic acid, carnosine, acetyl tetrapeptide-5, arginine / lysine polypeptide, palmitoyl tripeptide-5, and acetyl hexapeptide-8.

[0046] In some embodiments, the anti-aging active component may include bisphosphonium and palmitoyl tripeptide-5, and the mass ratio of bisphosphonium to palmitoyl tripeptide-5 is 1:1.

[0047] In the embodiments of the present application, the above-mentioned components are selected as the anti-aging active components. On the one hand, they have good anti-aging effects and can penetrate into the skin well with the assistance of the fruit acid compound to play a highly effective anti-aging role. On the other hand, they have high tolerance in an acidic system and can be used in combination with fruit acid to effectively resist aging symptoms.

[0048] In some embodiments, the emulsifier may include two or three of fatty alcohol polyoxyethylene ethers, sorbitan fatty acid esters, cetearyl glucoside, cetearyl olivate, laureth-13, PEG-40 hydrogenated castor oil, and sorbitan olivate.

[0052] In some embodiments, the oil phase component may include isononyl nonanoate, olive fruit oil and squalane, and the mass ratio of isononyl nonanoate, olive fruit oil and squalane is (0.5-8):1:1.

[0053] In some embodiments, the water phase component may include water and a water phase additive, wherein the water phase additive includes one or more of glycerol, propylene glycol, 1,3-propanediol, butylene glycol, methyl gluceth-20, and methylpropylene glycol.

[0055] In some embodiments, the water-soluble polymer may include one or more of polyacrylic acid, sodium polyacrylate, polyacrylate cross-linked polymer, Chondrus crispus, sodium alginate, cellulose, and Sphingomonas fermentation product extract.

[0056] In some embodiments, the water-soluble polymer may include Chondrus crispus and Sphingomonas fermentation product extract, and the mass ratio of Chondrus crispus to Sphingomonas fermentation product extract is 1:(2-6).

[0057] By limiting the composition ratio of water-soluble polymers within the above range, the problem of collapse of the emulsification system caused by high concentration of fruit acid can be effectively improved. It can cooperate with the emulsifier to form a certain steric hindrance, reduce the aggregation of oil droplets, and improve the stability of the anti-aging essence lotion.

[0058] In the embodiments of the present application, by optimizing the combination of oil phase components, water-soluble polymers and emulsifiers from green sources, through their synergistic effect, the mildness, moisturizing, spreadability and texture of the anti-aging essence milk can be effectively improved, satisfying the consumer's demand for refreshing, moisturizing and non-greasy skin feeling when using acid-containing products. And the phospholipid bilayer structure of this anti-aging essence milk close to the skin can further improve the efficient penetration of the effective ingredients. The pH value of the anti-aging essence milk can be controlled to be above 4, which is gentle and non-irritating. As a resident product, it can prolong the action time of the active ingredients and give full play to its anti-aging and moisturizing effects.

[0094]

[0095]

[0096] 2. Firming effect test

[0097] The portable skin elasticity tester Elastimeter (Delfin, Finland) was used to test the instant skin elasticity of the subjects on the 0th day (D0), the 14th day (D14), and the 28th day (D28) of using the anti-aging essence, and then the firming efficacy test value was obtained. Among them, those that failed the stability test were not tested for efficacy.

[0098] The test results are shown in Table 3.

[0099] 3. Anti-wrinkle efficacy test

[0100] Use the skin detector VISIA 7 (Canfield, USA), clean the test area with a uniform cleansing product before the test, and collect images and evaluate the grades of the subjects before using the product, which is recorded as the initial value (wrinkle area). When taking pictures, the subjects close their eyes and relax. Distribute test samples, and guide the subjects to use them according to the instructions for use of the samples to ensure that the subjects can use the products correctly and continuously, and the product use area must cover the test area. At the set test time points (Day 0 (D0), Day 14 (D14), Day 28 (D28)), image collection and grade evaluation are performed again, which is recorded as the measured value (wrinkle area). The product was not used on the day of the experiment, and the entire test cycle was 4 weeks. The results are shown in Table 16.

[0103]

[0104] In the examples of the present application, the fruit acid compound obtained by selecting a small molecule fruit acid and a large molecule fruit acid, and using it in combination with the anti-aging active ingredient can make the anti-aging essence milk have good anti-aging performance. Referring to the performance data in Table 2 and Table 3, combined with the data comparison of Examples 1-3 and Comparative Examples 4-6, the combination of the fruit acid compound and the anti-aging active ingredient can significantly enhance the firming effect and anti-wrinkle effect of the anti-aging essence milk.

[0105] The anti-aging essence milk in Examples 1-3 and Comparative Examples 1-3 uses fruit acid compounds with different composition ratios. Combined with the performance data in Tables 2 and 3, the fruit acid compounds in Examples 1-3 using small molecule fruit acids and large molecule fruit acids can make the product have better anti-aging performance. In Comparative Examples 1-3, only small molecule fruit acids / large molecule fruit acids were used respectively. It can be seen that the anti-aging effect of the product has been significantly reduced, which shows that the compounding of large molecule fruit acids and small molecule fruit acids is necessary and effective for improving the anti-aging effect. It also verifies that the compounding of small molecule fruit acids and large molecule fruit acids in this application can enhance the penetration of active ingredients, making them play a greater value, and it itself also has a good effect of promoting collagen and lifting and tightening the skin.

[0106] Further analysis of the performance data of Examples 1-5 shows that the use of glycolic acid, lactobionic acid and gluconolactone in Example 1 in a specific ratio can further enhance the anti-wrinkle effect of the anti-aging essence. The composition ratio of the anti-aging active components in Examples 6 and 7 was adjusted, and their firming and anti-wrinkle effects were somewhat reduced compared to Example 1, which shows that the specific ratio of anti-aging active components in Example 1 of the present application also has a certain effect on enhancing the anti-aging effect of the product.

[0107] It should be noted that the present application is not limited to the above-mentioned embodiments. The above-mentioned embodiments are only examples, and the embodiments having the same structure as the technical idea and exerting the same effect within the scope of the technical solution of the present application are all included in the technical scope of the present application. In addition, without departing from the scope of the main purpose of the present application, various modifications that can be thought of by those skilled in the art to the embodiments and other methods of combining some of the constituent elements in the embodiments are also included in the scope of the present application.
