Description

Technical Field

[0001] The invention relates to the field of cosmetics, and in particular to an emulsified wash-free facial cleanser with whitening and anti-aging effects and a preparation method thereof. Background Art

[0002] Skin aging includes internal and external factors. Internal factors: With the increase of age, the collagen in the skin will gradually be lost, causing the skin to sag, the pores to become larger, and fine lines to appear. The reduction of collagen will cause the elastic network supporting the skin to break, lose elasticity, and sag, and the skin will shrink and collapse, showing an old appearance. In addition, the metabolism of the skin slows down, the number of new cells decreases, and the normal metabolism of dead skin also slows down, resulting in the accumulation of dead skin, making the skin dull and rough. External factors: Photoaging is an important factor leading to aging. Ultraviolet rays can cause fine lines and spots on the skin, and also make the skin lose elasticity and luster. In addition to photoaging, the increasingly serious urban pollution is also a big test for the skin. Enlarged pores and dullness caused by haze and radiation are also very common skin problems. Urban women face heavy pressures in life and work, and their skin is also overwhelmed. Stress can cause sugar in the blood to form harmful substances, denature proteins, and lead to reduced skin elasticity, dull skin color, and pigmentation. Cleansing the skin has become a daily task that cannot be ignored and is an important step in protecting the skin.

[0003] At present, there are mainly the following types of cleansers on the market in terms of ingredients: 1. Soap-based cleansers: strong decontamination and degreasing abilities, but the skin will obviously feel dehydrated and tight after use, which can easily damage the skin; 2. Surfactant cleansers: relatively mild and non-irritating, but there will still be tightness and dehydration after use, weak decontamination ability, and residue after rinsing; 3. Emulsifying cleansers: no discomfort such as tightness and dehydration after use, but the decontamination and degreasing abilities are the worst, and the cleaning ability is the worst; 4. Amino acid cleansers: amino acids themselves are weakly acidic, which just fits the pH value of the skin, will not affect the pH value of the skin, have little irritation to the skin, are particularly skin-friendly, have moderate cleaning power, no residue after use, avoid the damage of residual substances to the natural protective layer of the skin, and have good foaming performance. In terms of efficacy, in addition to cleaning the skin, most of the cleansers on the market have hydrating, moisturizing and whitening effects, but there are few products that have whitening and anti-aging effects at the same time. This is because anti-aging active ingredients added to cleansing products are not easy to stay and be absorbed by the skin to exert their due effects.

[0004] Currently, the facial cleansing products on the market have single functions, generally only having cleansing functions, mild soothing functions, etc., and have few whitening and anti-aging functions, which are difficult to meet the needs of consumers.

[0005] Patent CN201510793627.1 discloses a whitening and anti-aging facial cleanser and a preparation method thereof, including lauric acid, glycerin, potassium hydroxide, squalane, sodium lauroyl glutamate, glyceryl monostearate, polyethylene glycol, eucommia extract, moringa leaf extract, ophiopogon extract, ginkgo leaf extract, disodium EDTA, methylparaben, essence and water. The whitening and anti-aging facial cleanser is mild and skin-friendly, safe and non-irritating, deeply cleanses the skin, promotes blood circulation, replenishes water and whitens, and delays aging. However, the cleanser is a wash-off product, and it is inevitable that the effective substances will be washed off during use, making the effective substances inefficient.

[0006] In summary, in order to overcome the problem that the whitening substances are washed away, resulting in low efficiency in the use of whitening substances, the present invention adopts a wash-free dosage form to maximize the efficiency of the use of whitening substances. Summary of the invention

[0007] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide an emulsified wash-free facial cleanser with whitening and anti-aging effects and a preparation method thereof.

[0039] Furthermore, the stirring and homogenizing in step c is: stirring at 250-350 rpm for 3-5 minutes and then homogenizing at 2500-3500 rpm for 3-10 minutes;

[0040] The stirring and homogenizing in step d is as follows: stirring at 250-350 rpm for 3-5 min and then homogenizing at 2500-3500 rpm for 3-10 minutes.

[0041] The stirring and homogenizing in step e is as follows: stirring at 250-350 rpm for 3-5 min and then homogenizing at 2500-3500 rpm for 3-10 minutes;

[0042] The stirring and homogenizing in step f is: stirring at 250-350 rpm for 3-10 minutes and then homogenizing at 2500-3500 rpm for 3-10 minutes.

[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] 1. The present invention uses madecassoside, benzoin and undecylenylphenylalanine in combination to achieve the purpose of synergistic enhancement. Among them, the extract of Centella asiatica leaf has significant anti-inflammatory and antioxidant properties, can resist the damage of free radicals to the skin, delay skin aging, and can also stimulate the skin to produce collagen, enhance skin elasticity and firmness, and is helpful for improving skin sagging, fine lines and other problems. benzoin can stimulate the production of skin aminoglucan (GAGs), help improve the firmness of cells, enhance the elasticity of the skin, and prevent the loss of skin moisture; undecylenylphenylalanine can effectively inhibit the formation of melanin caused by α-MSH, and can act on multiple stages of melanin formation, and is used for whitening or reducing the deposition of epidermal melanin, improving skin problems such as dull yellow and roughness, even skin color, and preventing, delaying and treating excessive pigmentation in the skin (such as excessive pigmentation after inflammation, spots such as age spots, etc.).

[0045] The present invention uses madecassoside, benzoin and undecylenoyl phenylalanine in combination to improve skin from the aspects of anti-allergy and anti-inflammation, promoting collagen production and resisting melanin production, and plays a synergistic anti-aging effect in facial cleansing products.

[0046] Furthermore, since the product is prepared in a cream form, when used, it is similar to applying a cream product and does not need to be rinsed with water, so that the added active ingredients will not be lost with the cleansing water, but can remain and be absorbed by the skin to exert their due effects.

[0047] 2. The present invention uses a mild, wash-free facial cleanser as a carrier, and adds the above three raw materials therein. In terms of the dosage form, an emulsified facial cleanser is selected, and light oils, mild emulsifiers, thickeners, and mild auxiliary raw materials are selected to bring a low-irritation or even no-irritation feeling to the facial skin from an exogenous source. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Figure 1 The following is a data graph showing the skin L* value of each embodiment and comparative example after using the sample. DETAILED DESCRIPTION

[0049] The present invention is described in detail below with reference to specific embodiments.

[0050] The present invention selects a specific ratio of madecassoside, benzoin, and undecylenoyl phenylalanine in combination for use in a facial cleanser to achieve a synergistic anti-aging effect, improving the skin from the aspects of anti-allergy and anti-inflammatory, promoting collagen production, and resisting melanin production. The specific description is as follows:

[0051] 1. Madecassoside

[0052] Madecassoside is a triterpenoid saponin, the main active ingredient extracted from Centella asiatica of the Umbelliferae family. It has anti-inflammatory, antioxidant and wound healing effects and can be used to treat skin damage and inflammation.

[0053] Madecassoside works by inhibiting excessive cell proliferation and inflammatory responses. It can regulate the epidermal growth factor receptor pathway, thereby reducing scar formation. Centella asiatica leaf extract has significant anti-inflammatory effects and can help reduce skin inflammation and redness. At the same time, it also has antioxidant properties, which can resist free radical damage to the skin and delay skin aging. Madecassoside can stimulate the skin to produce collagen, enhance skin elasticity and firmness, and is helpful in improving skin sagging, fine lines and other problems.

[0054] 2. Bosone

[0055] Bosin was originally discovered from beech trees. It is a mixture of glycoproteins derived from xylose and is a xylose derivative with anti-aging active ingredients. It can stimulate the production of skin aminoglucosamine (GAGs). GAGs are the main components of the extracellular matrix, and hyaluronic acid contained in them is one of the main components of GAGs. Hyaluronic acid has a strong ability to absorb and store water. When injected into the dermis, it can achieve the effect of filling and moisturizing the skin, making the skin plump and elastic. Hyaluronic acid is also often used to fill the concave parts of the skin, including wrinkles. Because mucopolysaccharides can absorb moisture, the matrix network structure is more elastic, which helps to improve the firmness of cells and enhance the elasticity of the skin. It plays a role in preventing the loss of moisture from the skin.

[0056] 3. Undecylenoylphenylalanine

[0057] Undecylenoyl phenylalanine is a compound containing amino acids and a melanin stimulating hormone (α-MSH) receptor antagonist. It acts on the biochemical reactions at various stages of melanin formation caused by α-MSH, intercepts melanin production signals, controls the combination of α-MSH (melanocyte stimulating hormone) and melanin production factors, effectively inhibits the activity of tyrosinase, and thus inhibits the formation of melanin. It is mainly used in cosmetics as a whitening agent.

[0058] It can effectively inhibit the formation of melanin caused by α-MSH, and can act on multiple stages of melanin formation. It is used to whiten or reduce the deposition of epidermal melanin, improve skin problems such as dullness and roughness, even out skin tone, prevent, delay and treat excessive pigmentation in the skin (such as excessive pigmentation after inflammation, spots such as age spots, etc.).

[0059] Acylamidin can be combined with niacinamide. Acylamidin can prevent melanin synthesis from the source (i.e. inhibit melanin production signals and inhibit melanin production enzyme activity), while niacinamide interferes with the melanin synthesis pathway (i.e. inhibit melanin transport to the stratum corneum and accelerate melanin stratum corneum metabolism). They work together to achieve whitening and spot-lightening effects. It can be used to prepare stable, non-discoloring lotions, creams, transparent aqueous solutions or gels, etc.

[0060] 4. Synergy

[0061] Skin aging generally includes skin sagging and wrinkling, dull complexion, and susceptibility to inflammation. Corresponding anti-aging requires improving the skin from the aspects of anti-allergy and anti-inflammation, promoting collagen production, and resisting melanin production. The present invention uses a combination of madecassoside, benzoin, and undecylenoyl phenylalanine in a cleansing product to achieve a synergistic anti-aging effect.

[0062] The following is a detailed description through specific examples. The raw materials and detection methods involved in the present invention are commonly used raw materials and detection methods in the art unless otherwise specified.

[0063] The emulsified cleanser of the present invention comprises three key components, namely, madecassoside, benzoin and undecylenoyl phenylalanine, as well as polyols, oils, emulsifiers, thickeners and pH regulators. Preferably, the raw materials for preparing the emulsified cleanser with whitening and anti-aging effects also include preservatives and fragrances.

[0064] The raw material formula of the emulsified cleanser of the present invention includes the components and amounts as shown in Table 1 below:

[0065] Table 1 Raw material formula of emulsified cleanser

[0079] f. After cooling to 35-38°C, stir at 300 rpm for 3 minutes, and then homogenize at 3000 rpm for 3 minutes to obtain the desired emulsified cleanser.

[0080] Characterization data and effect data of the products of the embodiments and comparative examples

[0081] The three functional components in Comparative Examples 1-3 are only added separately, which is used to compare the effectiveness of each active component with the blank control sample. Comparative Examples 4-6 contain two functional components, and Examples 1-5 contain three functional components at the same time, and the difference in the different dosages is only the addition of each active component. The preparation methods are all the same.

[0082] Change rate = (analysis value after using the product - analysis value before using the product) ÷ analysis value before using the product × 100% Test experiment and its results:

[0083] Data and grouping of test subjects: 240 female test volunteers with healthy skin and no history of skin allergies, aged 25 to 55, with an average age of 35, were randomly divided into 12 groups, 20 people in each group. Test volunteers used the sample once in the morning and evening every day, taking 2-5 grams each time and applying it evenly on the face, massaging for 1-2 minutes, and then wiping with a cotton towel. The first group of consumer testers used the control sample, the second group used the sample of comparative example 1, and so on. The data on the 0th day, the 14th day, the 28th day, and the 56th day were tested respectively.

[0084] (1)TEWL(g / m 2 / h) Transepidermal water loss test

[0085] The transepidermal water loss (TEWL) is accurately measured using the non-invasive measurement device TEWL (Dermalab Combo). If the TEWL decreases significantly before and after the use of the test product, it means that the skin barrier has been restored and the product has a repairing effect.

[0086] Table 3TEWL (g / m 2 / h) Change rate of transepidermal water loss (%)

[0087]

[0088] As can be seen from Table 3 above, the total amount of the functional ingredients of Comparative Examples 1-6 and Example 2 is the same, wherein Example 2 contains three functional ingredients, namely, madecassoside, benzoin, and undecylenylphenylalanine, and has the best effect on improving the water loss of the skin, proving that the three functional ingredients of the present invention have good systemic effects, while Comparative Examples 1-6 contain one or two of the three functional ingredients. Compared with the blank control example, it can be seen that the three functional ingredients can improve the water loss of the skin well, benzoin has a relatively good effect, followed by madecassoside, and then undecylenylphenylalanine. The three are compounded, and the effect is better than that of using them alone.

[0089] The dosage of the functional ingredients in Examples 1-5 is respectively Example 5> Example 4> Example 2> Example 3> Example 1. The corresponding effects are Example 5> Example 4> Example 2> Example 3> Example 1, because although Example 1 contains three functional ingredients, the dosage is less, so the effect is poor.

[0090] (2) Skin stratum corneum moisture content detection

[0091] Corneometer CM825 was used to measure the moisture content of the stratum corneum after using the sample.

[0092] Table 4. Water content of the stratum corneum within and between groups

[0093]

[0094] The above results show that the total amount of effective ingredients in Comparative Examples 1-6 and Example 2 is the same, wherein Example 2 contains three effective ingredients, namely, madecassoside, benzoin, and undecylenylphenylalanine, and has the best moisturizing effect. When Comparative Examples 1-3 of madecassoside, benzoin, and undecylenylphenylalanine are used alone in the wash-free emulsified cleanser, benzoin has a better moisturizing effect (Comparative Example 2), followed by asiaticaside (Comparative Example 1), and finally undecylenylamide phenylalanine (Comparative Example 3). When the three are used in combination, they can exert a better moisturizing effect.

[0095] The dosage of the functional ingredients in Examples 1-5 is respectively Example 5> Example 4> Example 2> Example 3> Example 1. The corresponding moisturizing effects are Example 5> Example 4> Example 2> Example 3> Example 1. This is because although Example 1 contains three functional ingredients, the dosage is small, so the effect is poor.

[0096] (3) Detection of improved skin elasticity

[0097] Cutometer MPA580 was used to test skin wrinkles and skin elasticity to detect whether there was any improvement after using the sample. The R2 value is the ratio of the skin's rebound without negative pressure to the maximum stretch value with negative pressure. The R5 value is the ratio of the elastic part of the skin recovery process to the elastic part of the negative pressure process in the first cycle of the skin test. The R7 value is the ratio of the elastic part of the skin recovery process to the maximum stretch value of the skin during this cycle in the first cycle of the skin test. The closer the three parameters are to 1, the better the elasticity. Statistics of elasticity data changes before and after using the sample, compared with before using the sample:

[0098] Table 5. Data statistics of skin elasticity change ratio after use of each sample (%)

[0099]

[0100]

[0101] As can be seen from Table 5 above, from the perspective of elasticity change, Comparative Examples 1-3 use one functional component, and the effect is better than the blank control example. The contribution of asiatica (Comparative Example 1) and benzoin (Comparative Example 2) to the improvement of skin elasticity is greater than that of undecylenamide phenylalanine (Comparative Example 3). Comparative Examples 1-6 and Example 2 have the same total amount of functional components, wherein Example 2 contains three functional components, namely, madecassoside, benzoin, and undecylenamide phenylalanine, and the effect of improving elasticity is better than that of Comparative Examples 4-6 containing only two of the functional components. Moreover, since Comparative Examples 1-3 contain only one functional component, it is proved that the three functional components of the present invention have a synergistic effect.

[0102] The dosages of the functional ingredients in Examples 1-5 are respectively Example 5> Example 4> Example 2> Example 3> Example 1. The corresponding elasticity improvement effects are Example 5> Example 4> Example 2> Example 3> Example 1.

[0103] (4) Skin color improvement detection

[0104] The full-face photos of the subjects were collected using Visia-CR, and then the skin color L*, a*, and b* of the skin color in the AOI area of ​​the subjects were analyzed using Image-Pro Plus. The L* value represents the brightness of the skin. The larger the value, the more the color tends to be white, and vice versa. The a* value represents the red-green degree, +a is the red direction, -a is the green direction, the larger the value, the more the skin tends to be red; the b* value represents the blue-yellow degree, +b is the yellow direction, -b is the blue direction, the larger the value, the more the skin color tends to be yellow. The measured L* and b* values ​​can be used to calculate: individual typological angle (ITA°): ITA°=ArcTangent[(L*-50) / b*]*180x 3.14l6, ITA° is the value of colipa specified by the above formula to characterize the brightness of the skin. The larger the ITA° value, the brighter the skin, and vice versa, the darker the skin.

[0105] Table 6. L* values ​​of skin after using samples

[0106]

[0107] Figure 1 This is the skin L* value data after using the sample

[0108] Combination Figure 1 From Table 6, it can be seen that in terms of skin whitening, the effect of undecylenamide phenylalanine is significantly better than that of asiatica and benzoin (i.e., the L* value of Comparative Example 3 is higher than that of Comparative Examples 1-2). However, the addition of benzoin has a synergistic effect on the skin whitening effect of undecylenamide phenylalanine (i.e., the L* value of Comparative Example 6 is higher than that of Comparative Examples 4-5). The total amount of effective ingredients of Comparative Examples 1-6 and Example 2 is the same, wherein Example 2 contains three effective ingredients of madecassoside, benzoin, and undecylenamide phenylalanine at the same time, and the L* value of Example 2 is higher than that of Comparative Examples 1-6, proving that the effect of adding the three effective ingredients of asiatica, benzoin, and undecylenamide phenylalanine at the same time is significantly better than that of any two ingredients, proving the synergistic effect of the three.

[0109] (5) Consumer trial evaluation

[0110] While the above instrument tests are being conducted, all testers will simultaneously conduct consumer trial evaluations. Observe and feel the effects of use. Use the product for 8 weeks, check at least once a week to see if there are any systemic or local adverse reactions, and record the results in detail. Record the consumer self-evaluation on the 56th day.

[0111] The test evaluation results are as follows:

[0137]

[0138] According to the statistics of self-evaluation by consumers, benzoin is more effective than asiatica glycyrrhizin in improving skin moisture and elasticity, while undecylenamide phenylalanine has no obvious effect on improving elasticity. In terms of brightening skin tone, undecylenamide phenylalanine is more effective than benzoin and asiatica glycyrrhizin. However, the combination of the three ingredients is better than using a single ingredient in terms of skin moisture, smoothness, elasticity, brightening skin tone, and improving fine lines and wrinkles. benzoin has a synergistic effect with undecylenamide phenylalanine in brightening skin color.

[0139] The invention can be understood and used by those skilled in the art. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the present invention is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the scope of protection of the present invention.
