Description

Technical Field

[0001] The present invention belongs to the technical field of skin care products, and in particular relates to a moisturizing and whitening composition capable of promoting penetration and absorption and an application thereof in skin care products. Background Art

[0002] Most skincare products currently on the market only work on the surface of the skin. While they can quickly hydrate the skin, effective moisturizing ingredients struggle to penetrate the stratum corneum, leading to water evaporation and rapid dehydration. This makes it difficult to achieve long-lasting moisturizing, whitening, and anti-wrinkle effects. Phytoestrogens, particularly soy isoflavones found in leguminous plants, have attracted widespread attention due to their ability to bind to estrogen receptors and exhibit multiple physiological functions, including bidirectional regulation of estrogen levels in women and improvements in menopausal symptoms, osteoporosis, and cardiovascular disease. They also offer significant cosmetic benefits, including antioxidant and anti-aging effects, improved skin texture, and a smoother, more elastic complexion.

[0003] However, skin care products usually rely on natural penetration to allow active ingredients to enter the skin, but the natural barrier function of the stratum corneum leads to low absorption efficiency of active ingredients, and most of them remain on the surface of the skin, making it difficult to exert deep effects. Although chemical penetration enhancers can increase the amount of penetration, their irritation and side effect risks make it necessary to develop safe penetration enhancement technologies. The molecular weight of substances that penetrate the skin is usually below 500Da, but the penetration efficiency of low molecular weight substances is not necessarily high, and the penetration efficiency of high molecular weight substances such as growth factors is even lower. This makes the cosmetics industry in urgent need of safe and effective methods for delivering bioactive substances.

[0004] Phytoestrogens used in cosmetics or skin care products can improve skin health in multiple ways, including moisturizing, whitening, and anti-aging. However, phytoestrogens cannot penetrate the stratum corneum well for the following reasons:

[0005] (1) Skin barrier function. The stratum corneum is composed of multiple layers of keratinocytes and lipids. Its tightly arranged structure forms a natural barrier that can effectively prevent the invasion of external substances, including phytoestrogens. In particular, phytoestrogens with larger molecular weights or stronger polarity are more difficult to penetrate this barrier. (2) Molecular property limitations and poor water solubility. Some phytoestrogens have larger molecular weights, such as puerarin, which has a molecular weight of 416 Da. Its molecular volume is relatively large, making it difficult to pass through the tiny gaps between stratum corneum cells, thereby limiting its penetration into the skin. Some phytoestrogens have poor water solubility and are not easy to dissolve and disperse on the skin surface. They are difficult to enter the stratum corneum through the skin's aqueous channels. The stratum corneum of the skin is mainly composed of lipids and keratin and has a certain degree of hydrophobicity, which limits the permeability of water-soluble phytoestrogens. (3) Usage concentration issues. In skin care products, the concentration of phytoestrogens is usually limited; too low a concentration may result in insufficient penetration on the skin surface, making it difficult to exert significant effects.

[0006] Therefore, optimizing the penetration-enhancing technology to promote the penetration of phytoestrogen active substances in the skin barrier, improve stability, and reduce irritation without damaging the skin barrier are difficult problems that need to be solved in the process of achieving the efficacy of cosmetics. Summary of the Invention

[0007] The purpose of the present invention is to address the above-mentioned problems and provide a moisturizing and whitening composition that effectively promotes penetration and absorption and its application in skin care. Without irritating or damaging the skin, the composition and ratio of the penetration enhancer are optimized to significantly improve the penetration ability of phytoestrogen active substances in the skin barrier, thereby effectively solving the problems of low phytoestrogen penetration efficiency and skin barrier damage in the prior art.

[0008] The invention relates to a moisturizing and whitening composition for promoting penetration and absorption. The composition comprises the following raw material components in parts by weight: 1-15 parts of a penetration enhancer, 5-10 parts of phytoestrogen powder, 1-5 parts of a polypeptide, and 1-8 parts of a biosurfactant.

[0009] Preferably, the penetration enhancer is phospholipid polyethylene glycol carboxyl, limonene, and menthone, wherein the mass ratio of phospholipid polyethylene glycol carboxyl, limonene, and menthone is 5-10:1-5:0.5-1.

[0010] Preferably, the molecular weight of the polyethylene glycol in the phospholipid polyethylene glycol carboxyl group is 300-3000. Further preferably, the molecular weight of the polyethylene glycol (PEG) in the phospholipid polyethylene glycol carboxyl group is 750-2000.

[0011] Preferably, the polypeptide is one or more of acetyl hexapeptide-8, palmitoyl tripeptide-1 and palmitoyl tetrapeptide-7.

[0012] Preferably, the phytoestrogen powder is at least one of red clover extract, soybean stem extract, linseed extract, and kudzu root extract. Particularly preferably, the phytoestrogen powder is a combination of red clover extract, soybean stem extract, linseed extract, and kudzu root extract in a mass ratio of 1:2-3:1-3:0.5-1.

[0013] Preferably, the biosurfactant is at least one of sodium cocoyl glutamate, lecithin, coco-glucoside, cocamidopropyl betaine, and cocamidopropyl hydroxybetaine.

[0014] The application of the phospholipid polyethylene glycol carboxyl group (DSPE-PEG-COOH) used in this invention in cosmetics and skincare products is primarily due to its unique chemical structure and properties. The phospholipid portion imparts excellent biocompatibility and cell membrane permeability, making it a carrier for active ingredients in skincare products, improving their stability and bioavailability. The terminal carboxyl group can be covalently coupled with a variety of bioactive molecules, achieving functional modification and enhancing the efficacy of the cosmetic or skincare product. It also exhibits excellent biocompatibility and safety, is non-irritating to the skin, and does not cause allergic reactions. It can be used as an ingredient in moisturizing creams, serums, foundations, and other products, improving their moisturizing effect, dispersibility, and stability. DSPE-PEG-COOH is also an amphiphilic macromolecule. The hydrophobic phospholipid (DSPE) portion can embed into the lipid structure of the skin's stratum corneum, while the hydrophilic PEG chain forms a hydrophilic barrier, extending the retention time of active ingredients in the skin's surface layer. The terminal carboxyl group (-COOH) can bind to estrogen through hydrogen bonds, enhancing the penetration of phytoestrogens.

[0015] The phospholipid polyethylene glycol carboxyl group, limonene, and menthone in the penetration enhancer of the present invention work together to enhance the phytoestrogens to penetrate the stratum corneum more effectively and enter the deep layers of the skin to exert their effects. Excessive or low content of phospholipid polyethylene glycol carboxyl group, limonene, and menthone has a significant impact on the permeability of phytoestrogens and the performance of skin care products. A mass ratio of 3-10:1-5:0.5-1 can better promote the permeability of phytoestrogens. Too high a concentration of phospholipid polyethylene glycol carboxyl group will hinder the interaction between phytoestrogens and cell membranes, reducing permeation efficiency; too low a concentration will not effectively enhance the stability of phytoestrogens and improve their interaction with cell membranes. Too high a concentration of limonene will destroy the structure of the skin's stratum corneum, hinder the penetration of phytoestrogens, and may cause irritation, reduce user experience, and even cause allergies; too low a concentration will have limited permeation-promoting effects. Too high a concentration of menthone will cause skin irritation, such as itching, stinging, erythema, etc., causing discomfort to users, disrupting the absorption function of skin cells, reducing the permeation effect of phytoestrogens, and affecting users' comfort and satisfaction with skin care products.

[0016] The present invention prefers sodium cocoyl glutamate, lecithin, cocoyl glucoside, cocamidopropyl betaine, and cocamidopropyl hydroxybetaine as dispersants. Compared to other types of surfactants, these biosurfactants not only effectively promote the dispersion and penetration of phytoestrogens in skin care products, but are also gentler and non-irritating to the skin. They also possess a certain moisturizing ability, forming a protective film on the skin surface to reduce water loss and keep the skin hydrated.

[0017] The limonene and menthone penetration enhancers of the present invention can increase the permeability of the intercellular channels in the stratum corneum, enabling efficient transdermal delivery of estrogen. However, prolonged expansion of the stratum corneum to increase permeability can damage the skin. Therefore, the present invention incorporates a polypeptide component into the penetration enhancer composition. The polypeptide has a structure similar to components such as proteins and amino acids in the skin and can interact with related components in the stratum corneum to repair the stratum corneum enlarged by limonene and menthone, thereby repairing the skin barrier. Furthermore, the polypeptide has a certain moisturizing ability, absorbing and locking in moisture, increasing the skin's water content and making the stratum corneum more hydrated and softer.

[0018] The penetration-enhancing composition for promoting estrogen absorption of the present invention works synergistically through multiple mechanisms: DSPE-PEG-COOH acts as a carrier of the active ingredient of phytoestrogen, enhancing the penetration performance of phytoestrogen; limonene and limonone can expand the permeability of the channels between stratum corneum cells, repairing the skin barrier, jointly achieving efficient penetration of estrogen and completing the repair of stratum corneum cells.

[0019] Furthermore, among the phytoestrogens used in the present invention, the isoflavone compounds in red clover extract, the soy isoflavones in soybean stem extract, the lignans in flaxseed extract, and the puerarin in kudzu root extract all have phytoestrogen functions. These ingredients can mimic the effects of estrogen, regulate hormone levels, and have a positive impact on skin health. In addition to its phytoestrogen effects in skin care products, red clover extract also has antioxidant, anti-inflammatory, and soothing properties, making it suitable for sensitive skin. Soybean stem extract can promote collagen synthesis and moisturize; flaxseed extract has strong moisturizing and repair and regeneration effects; and kudzu root extract has antioxidant, anti-inflammatory, and microcirculation-enhancing effects. A particularly preferred combination of red clover extract, soybean stem extract, flaxseed extract, and kudzu root extract in a ratio of 1:2-3:1-3:0.5-1 is particularly preferred. This combination of four phytoestrogens can further improve skin moisturizing, delay skin aging, and enhance skin care results.

[0020] Furthermore, the present invention provides the use of the above-mentioned composition for promoting the absorption of phytoestrogens in skin care products, wherein the added amount of the components of the composition for promoting the absorption of estrogen is 1wt% to 50wt%, and the dosage form of the skin care product includes any one of a cream, lotion, water, mask or lotion.

[0021] Furthermore, in some embodiments of the present invention, the present invention also provides a moisturizing and whitening skin care product, which contains 1-50 wt % of the penetration-promoting composition.

[0022] Furthermore, the skin care product further comprises 1-15 wt % moisturizer, 3-8 wt % soothing agent, 0.5-2 wt % emollient, 0.5-2 wt % thickener, 0.1-2 wt % pH regulator, 0.1-1.5 wt % antibacterial agent, and the balance is water.

[0023] Preferably, the moisturizing agent is selected from at least one of butylene glycol, glycerin, dipropylene glycol, sodium hyaluronate and niacinamide.

[0024] Preferably, the soothing agent is selected from any one of swalnic acid, mannitol, trehalose, and ascorbic acid, or a combination of at least two thereof.

[0025] Preferably, the emollient is selected from at least one of dimethicone, dimethiconol, hydrogenated polyisobutene, cyclopentasiloxane and isononyl isononanoate.

[0026] Preferably, the thickener is selected from one or more combinations of xanthan gum, carbomer, sodium polyacrylate or hydroxyethyl cellulose.

[0027] Preferably, the pH regulator is selected from one of triethanolamine, sodium citrate, disodium hydrogen phosphate or a combination thereof.

[0028] Preferably, the antibacterial agent is selected from a combination of one or more of phenoxyethanol and p-hydroxyacetophenone.

[0029] Furthermore, the present invention also includes a method for preparing a skin care product, comprising the following steps: uniformly mixing the components in deionized water under stirring conditions to obtain a moisturizing and whitening skin care product.

[0030] The advantages or beneficial effects of the above technical solution include at least:

[0031] The penetration-enhancing composition of the present invention effectively delivers phytoestrogen active ingredients deep into the skin, providing excellent skin permeability and substitutability without irritating or damaging the skin. Application of the penetration-enhancing composition in skincare products can achieve multiple benefits, including long-lasting moisturizing, increased elasticity, and whitening. It also enables precise and sustained release of active ingredients, resulting in more targeted skincare results.

[0045] Phytoestrogen powder 5#, red clover extract, soybean stem extract, kudzu root extract, and kudzu root extract are mixed in a mass ratio of 1:2:1:1.

[0046] The embodiment and comparative example each relate to a moisturizing and whitening skin care emulsion, comprising component A and component B, wherein component A is a penetration-promoting composition containing a phytoestrogen that promotes absorption, and component B is composed of a moisturizer, a soothing agent, an emollient, a thickener, a pH adjuster, an antibacterial agent, and water.

[0052]

[0053] Performance evaluation:

[0054] 1. Transdermal absorption test of samples:

[0055] The estrogen in soybean stem extract is mainly daidzein. In the transdermal absorption experiment, the example and comparative example of phytoestrogen powder 2# (soybean stem extract) were tested. The main test methods are as follows:

[0056] Pig skin was used to simulate human epidermis. Pieces were cut into 10 cm x 5 cm sections with scissors and then soaked in saline for 30 minutes. This served as a transdermal barrier. The cosmetic under test was used as the transdermal release solution, and 30% ethanol-saline solution was used as the transdermal absorption solution. Transdermal absorption testing was conducted at a constant temperature of 37°C and a constant speed of 500 r / min. After 24 hours, 5 mL of the permeate was removed from the sample point using a clean syringe, and 5 mL of 30% ethanol-saline solution was added using a clean syringe. The flavonoid content of the samples was determined using high-performance liquid chromatography.

[0057] Flavonoid penetration rate = (amount of flavonoids in the receiving cell / amount of flavonoids in the emulsion) × 100%.

[0058] Table 3: In vitro percutaneous absorption test results

[0059]

[0060] The test results in Table 3 indicate that the skin care emulsion prepared in Example 2 of the present invention exhibited significantly higher in vitro transdermal permeation than the comparative example. This indicates that the three ingredients of the present invention, phospholipid polyethylene glycol carboxyl, limonene, and menthone, when combined in a specific mass ratio, can synergistically enhance the skin permeability of phytoestrogens. This improvement facilitates more efficient penetration of phytoestrogens through the stratum corneum, allowing them to penetrate deeper into the skin to fully exert their efficacy.

[0061] 2. Long-term moisturizing performance determination

[0062] Healthy female volunteers aged 35 to 55 were randomly divided into 17 groups, each with 5 participants. The skin care lotions provided in the Examples and Comparative Examples were used, and facial skin moisture content was quantitatively measured using a Corneometer CM825 at 0, 1, and 4 hours. By comparing the moisture changes before and after use, the long-lasting moisturizing ability of the products was evaluated to determine whether the phytoestrogens penetrate the skin barrier and reach deeper into the skin. The moisture content and moisturizing rate are the average values for each group. Moisturizing rate after 1 hour = 1 hour moisture content / 0 hour moisture content * 100; moisturizing rate after 4 hours = 4 hour moisture content / 0 hour moisture content * 100.

[0063] Table 4: Moisturizing performance test

[0064]

[0065] According to the test data in Table 4, the skin care emulsions of the Example and the Comparative Example had similar skin moisturizing rates after one hour of use. However, after four hours of use, the emulsion of the Example was able to stably maintain skin moisture content above 60%, while the emulsion of the Comparative Example caused a significant decrease in skin moisture content. This may be because the penetration enhancer used in the Example enables the phytoestrogens to penetrate deep into the skin and continuously release the active ingredients on the skin surface, thereby achieving a long-lasting skin care effect.

[0066] 3. Whitening test

[0067] Experimental Method: Healthy female volunteers aged 35-55 were randomly divided into 17 groups (5 participants per group). Each group used the skin care products of the Example and the Comparative Example for 30 consecutive days, once in the morning and once in the evening. The skin brightness changes (ΔL) before and after use were measured using a colorimeter, and the average values were calculated. The results are shown in Table 5.

[0068] Table 5: Whitening test results

[0069]

[0070] As shown in Table 5, the skin care lotions prepared in Examples 1-9 demonstrated significant advantages in terms of skin brightness change (ΔL), demonstrating excellent whitening effects. A comparison of Examples 2 and 5-8 reveals that the low-molecular-weight PEG DSPE-PEG-COOH possesses superior permeability, enabling phytoestrogens to more quickly penetrate the basal layer of the skin. This accelerates skin cell metabolism, allowing new cells to more quickly replace old melanin-containing cells, thereby achieving a whitening effect. In contrast, the phytoestrogens in Comparative Examples 1-6 were unable to penetrate deeper into the skin, failing to provide lasting skincare benefits on the surface, resulting in reduced whitening performance.

[0071] 4. Skin elasticity test

[0072] Volunteers were randomly assigned to 17 different groups, each containing 5 members. The test required each volunteer to use skin care lotion once a day, morning and evening. Skin elasticity was measured using a Cutometer skin elasticity tester produced by Courage & Khazaka, Germany, on days 0, 21, and 35. The cheek area was selected as the test point, and the measurement was repeated five times in the same test area to obtain the average value. Among them, the skin elasticity growth rate W% = 100% * (NT-N0) / N0; N0 - elasticity test value on day 0; NT - elasticity test value on day T. Specific skin elasticity test results are detailed in Table 6 below.

[0073] Table 6: Skin elasticity test results

[0074]

[0075] According to the test results in Table 6, after three weeks of use of the skin care emulsion of the present invention, the skin elasticity growth rate is greater than 12%, and after five weeks of continuous use, the skin elasticity growth rate exceeds 26%, giving the skin good elasticity. According to the comparison of Examples 2, 5-8, the effect of the molecular weight of PEG in DSPE-PEG-COOH on skin elasticity shows a trend of first increasing and then decreasing. Although low-molecular-weight DSPE-PEG-COOH can promote the rapid penetration of phytoestrogens to stimulate collagen synthesis and improve skin elasticity, the protective film formed is relatively thin, and the auxiliary effects such as moisturizing and anti-oxidation are limited, making it difficult to maintain long-term elasticity; high-molecular-weight DSPE-PEG-COOH forms a thick protective film, which simulates the elastic structure of the skin to improve the appearance of elasticity, but the permeability is reduced, affecting the absorption and utilization of phytoestrogens.

[0076] Comparative Examples 1-6 omitted phospholipid polyethylene glycol carboxyl, limonene, and menthone, or altered their ratios. This reduced the permeability of phytoestrogens in the skin's surface layer, making it difficult for them to cross the skin barrier and be effectively transported to the deeper layers of the skin. This in turn reduced the absorption and utilization efficiency of the phytoestrogens, leading to a significant decrease in skin elasticity. Comparative Example 8 omitted the biosurfactant, resulting in poor dispersibility of the phytoestrogens in the skin care lotion, which reduced their content in the deeper layers of the skin and decreased skin elasticity. Comparative Example 7 omitted the polypeptide, which also reduced skin elasticity.

[0077] 5. User experience evaluation

[0078] To evaluate the product experience, healthy female volunteers aged 35-55 were surveyed post-use, with each group receiving a 5-point scale rating (10-point scale). Each group used the emulsion from the example and the comparative example for 30 consecutive days, once daily in the morning and evening. The volunteers recorded any discomfort symptoms such as itching, burning, and persistent redness. The results are shown in Table 7 below:

[0079] Table 7: Experience evaluation test results

[0080]

[0081] The test results in Table 7 show that none of the volunteers using Examples 1-9 experienced any discomfort or allergic reactions, such as itching, burning, or persistent redness, during use. They also generally reported that the products were soft and comfortable, had a long-lasting moisturizing effect, and effectively brightened and removed freckles, resulting in an excellent overall user experience. In contrast, users of Comparative Example 2 reported mild erythema, likely due to the high menthone concentration, which caused skin irritation. Users of Comparative Example 7 reported suboptimal moisturizing and emollient properties, with a slight feeling of tautness on their skin after use. This is likely due to the omission of the peptide component, which causes the stratum corneum to expand under the long-term effects of limonene and menthone, but fails to repair the skin barrier in a timely manner.

[0082] The above embodiments are merely examples provided to illustrate the present invention and are not intended to limit the possible implementations of the present invention. Based on the disclosure of the present invention, those skilled in the relevant art may make various modifications and adjustments. It is neither possible nor necessary to enumerate all possible implementations. Any modification, equivalent substitution, or improvement made within the basic principles and scope of the present invention shall be deemed to fall within the scope of protection of the present invention.
