Description

Technical Field

[0001] The present invention relates to the technical field of cosmetics, and in particular to a penetration-enhancing composition, a preparation method thereof, and an application thereof. Background Art

[0002] As the largest organ in the human body, the skin possesses a powerful barrier function, protecting against the invasion of harmful substances from the outside world. However, this also hinders the skin's absorption of active ingredients. This is particularly true for active ingredients such as polyphenols and non-steroidal anti-inflammatory drugs, which have low permeability due to the barrier function of the skin's stratum corneum.

[0003] Transdermal absorption of cosmetics refers to the process by which the active or functional ingredients in cosmetics act on the skin surface or penetrate into the epidermis, dermis, and other skin layers, accumulating there and exerting their effective effects. The skin's barrier function results in poor transdermal permeability for many ingredients, making it difficult for the active ingredients in cosmetics to penetrate the skin and reach the body, preventing them from achieving their intended effects. Therefore, improving the transdermal permeability of these active ingredients is a pressing technical challenge in the research and development of cosmetics and topical medications.

[0004] In view of this, this application is filed. Summary of the Invention

[0015] As an embodiment of the present application, the weight average molecular weight of the hydrolyzed sodium hyaluronate is 3,000 to 10,000.

[0016] As an embodiment of the present application, the mass ratio of the sum of the mass of the hydrolyzed sodium hyaluronate and the yeast / rice fermentation product filtrate to the stabilizer is (1.1-2.5):1, preferably (1.625-2):1.

[0017] The second aspect of the present application provides a method for preparing a penetration-enhancing composition, comprising the following steps:

[0018] The hydrolyzed sodium hyaluronate, a stabilizer, a yeast / rice fermentation product filtrate and a solvent are uniformly mixed to obtain a penetration-enhancing composition.

[0028] Wherein, the raw materials of embodiment and comparative example are from following sources:

[0029] Among them, hydrolyzed sodium hyaluronate: weight average molecular weight is between 3000 and 10000, from Huaxi Biotechnology, brand Nano Highly active ultra-low molecular weight sodium hyaluronate (also known as Highly active oligomeric sodium hyaluronate).

[0030] Yeast / rice fermentation product filtrate: Angel Yeast Co., Ltd., brand FC01.

[0031] Thermus thermophilus fermentation filtrate: Hangzhou Umade Biotechnology.

[0032] Soy lecithin: Shanghai Yuanye Biological, product number S30869.

[0033] PEG-40 hydrogenated castor oil: Guangzhou Yiwan Biological, brand HK-HCO40.

[0034] PEG-60 hydrogenated castor oil: Guangzhou Yiwan Biological, brand HK-HCO60.

[0035] Sodium carboxymethyl cellulose-1: weight average molecular weight is 90500, viscosity of 2wt% aqueous solution at 25°C is 25-50mPa.s, degree of substitution is 0.7, Ashland, brand 7L9EP.

[0036] Sodium carboxymethyl cellulose-2: weight-average molecular weight is 90,500, viscosity of 2 wt% aqueous solution at 25°C is 50-100 mPa.s, degree of substitution is 0.7, Ashland, brand 7M1FPH.

[0037] Sodium carboxymethyl cellulose-3: weight-average molecular weight is 90,500, viscosity of 2 wt% aqueous solution at 25°C is 400-600 mPa.s, degree of substitution is 0.7, Ashland, brand 7MFPH.

[0038] Sodium carboxymethyl cellulose-4: weight-average molecular weight of 395,000, viscosity of 2 wt% aqueous solution at 25°C is 200-800 mPa.s, degree of substitution is 0.7, Ashland, brand 7M8SFPH.

[0039] The remaining raw materials are of conventional commercial cosmetic grade.

[0040] The present application provides an enhanced penetration composition, comprising the following components in parts by weight: 0.5 to 8 parts of hydrolyzed sodium hyaluronate, 5 to 20 parts of a stabilizer, 12 to 25 parts of a yeast / rice fermentation product filtrate, and 40 to 80 parts of a solvent;

[0041] The stabilizer comprises decapeptide-4, soybean lecithin, sodium carboxymethyl cellulose and a polyethylene glycol surfactant in a mass ratio of (0.05-0.4):(0.05-0.4):(0.08-0.5):1.

[0042] Among them, hydrolyzed sodium hyaluronate (serial number 06354 of the 2021 edition of the used cosmetic raw materials catalog) has excellent permeability. It can promote the penetration of active ingredients into the deep layers of the skin without damaging the skin barrier, gently release the active ingredients, promote effective absorption by the skin, and truly exert the efficacy of its ingredients. At the same time, hydrolyzed sodium hyaluronate can repair damaged cells, repair the skin barrier, increase cell activity, reduce the damage of the external environment to skin cells, penetrate into the subcutaneous tissue, promote the regeneration of subcutaneous cells, and accelerate skin metabolism.

[0043] Among them, the yeast / rice fermentation product filtrate (serial number 03446 of the 2021 version of the used cosmetic raw materials catalog): it is rich in oligosaccharides, organic acids (fruit acids), amino acids, small molecule peptides, etc., which can quickly enter the dermis through the gaps in the stratum corneum, enhance the skin's absorption capacity, and help other skin care ingredients to be better absorbed and utilized by the skin. It can also promote the renewal and metabolism of skin cells, making the skin healthier and more vibrant. It promotes the activity of fibroblasts and the proliferation of collagen, elastic fibers and hyaluronic acid, activates cell membrane water channel proteins, and endogenously increases the water content of the skin. The yeast / rice fermentation product filtrate can penetrate deeply into the skin, regulate the water and oil balance of the skin, and improve the oil secretion of the skin. It repairs the barrier function of the dermal matrix and replenishes the skin's own filaggrin or underlying fibers, thereby brightening the skin tone and improving skin texture. The yeast / rice fermentation product filtrate also has an antioxidant effect and can improve the stability of the composition.

[0044] Among them, the present invention uses decapeptide-4, soybean lecithin, sodium carboxymethyl cellulose, and polyethylene glycol surfactants as stabilizers. Decapeptide-4 can help open intercellular pathways, promote the penetration and absorption of biomacromolecules, promote the deep penetration of active ingredients into the bottom layer of the skin, and improve the absorption efficiency of active ingredients in the skin. At the same time, decapeptide-4 can soothe sensitivity, repair the stratum corneum, and reduce the sensitivity of the skin. It is added to the system in the form of a stabilizer. The composite stabilizer can not only improve the stability of the system, but also form intermolecular hydrogen bonds with water, increase the intermolecular force, and the molecules can be adsorbed and cross-linked with each other to effectively improve the stability of the system. It can also reduce surface tension, improve the permeability and wettability of the liquid, and at the same time, the positively charged groups can interact with negatively charged cells to destroy the permeability of the cell membrane, thereby changing the permeability of the cells. The stabilizer also has a certain soothing effect, creating conditions for the penetration of active ingredients and maintaining the water-oil balance of the skin.

[0045] The present invention creatively combines hydrolyzed sodium hyaluronate, a stabilizer, and a yeast / rice fermentation product filtrate according to the above-mentioned specific dosages. Under the joint action of hydrolyzed sodium hyaluronate, a stabilizer, and a yeast / rice fermentation product filtrate, the antioxidant effect and stability of the composition are improved, the skin barrier is repaired, and the moisturizing effect and skin elasticity of the composition are improved. The surface tension is effectively reduced, the permeability and wettability of the liquid are increased, and the permeability of the cell membrane is destroyed. Without destroying the skin barrier, the effective ingredients are promoted to penetrate deep into the skin, the effective ingredients are gently released, and effective absorption by the skin is promoted. Based on the complex action mechanism of hydrolyzed sodium hyaluronate, a stabilizer, and a yeast / rice fermentation product filtrate on the skin, the selection and ratio of the three ingredients also have a high degree of specific matching. If the types in the composition are replaced or the dosages of the three are changed, the penetration-promoting effect will be significantly reduced.

[0046] In one embodiment, the composition includes the following components in parts by weight: 2 to 6 parts of hydrolyzed sodium hyaluronate, 12 to 20 parts of stabilizer, 18 to 22 parts of yeast / rice fermentation product filtrate, and 56 to 64 parts of solvent. In particular, when the amount of each raw material is within this range, the compatibility is better, the synergistic effect is more obvious, and the penetration-enhancing effect can be further improved.

[0047] In one embodiment, the polyethylene glycol surfactant includes at least one of PEG-4 dilaurate, PEG-40 hydrogenated castor oil, and PEG-60 hydrogenated castor oil.

[0048] In one embodiment, the solvent includes at least one of isononyl isononanoate, dimethyl isosorbide, and an alcohol solvent.

[0049] In one embodiment, the solvent comprises isononyl isononanoate, dimethyl isosorbide and an alcohol solvent in a mass ratio of (0.1-0.4):(0.2-0.5):1.

[0050] Among them, dimethyl isosorbide has a strong ability to promote skin penetration and is gentle and non-irritating to the skin. It has a very strong dissolving power and promotes the active ingredients to break through the epidermal barrier and penetrate deep into the epidermis by dissolving the oil on the skin. Among them, isononyl isononanoate can improve the compatibility of the system, promote the rapid penetration of the active ingredients in the product into the skin, accelerate absorption and exert its efficacy. It can form a thin film on the skin surface, effectively locking in moisture and preventing moisture evaporation, thereby enhancing the skin's moisturizing ability. At the same time, it can enhance the skin's barrier function and improve the skin's resistance to the external environment. It can prevent damage to the skin caused by external factors. Among them, alcohol solvents can increase the solubility of active ingredients, improve the dispersion effect of active ingredients in the stratum corneum, prolong the action time of active ingredients, and indirectly increase the transdermal amount of active substances. The present invention uses isononyl isononanoate, dimethyl isosorbide and alcohol solvents as solvents, which not only improves the compatibility of the system and promotes the dissolution and dispersion of each ingredient, but also effectively improves the penetration effect.

[0051] In one embodiment, the alcohol solvent includes at least one of glycerol, 1,2-propylene glycol, 2,3-propylene glycol, 1,3-butanediol, 1,4-butanediol, 1,2-pentanediol, and isoprene glycol.

[0052] In one embodiment, the stabilizer includes decapeptide-4, soybean lecithin, sodium carboxymethyl cellulose, and polyethylene glycol surfactant in a mass ratio of (0.08-0.2):(0.08-0.2):(0.1-0.3):1.

[0053] In one embodiment, the weight-average molecular weight of the sodium carboxymethyl cellulose is 90,500 to 250,000, and the viscosity of a 2 wt % aqueous solution of the sodium carboxymethyl cellulose at 25° C. is 25 to 100 mPa.s. In particular, the use of sodium carboxymethyl cellulose with such a molecular weight and viscosity can better improve the stability of the system, increase the intermolecular force, and allow the molecules to adsorb and cross-link with each other to effectively improve the stability of the system. At the same time, it can also reduce surface tension and improve the permeability and wettability of the liquid.

[0054] In one embodiment, the weight average molecular weight of the hydrolyzed sodium hyaluronate is 3,000 to 10,000.

[0055] In one embodiment, the mass ratio of the sum of the mass of the hydrolyzed sodium hyaluronate and the yeast / rice fermentation product filtrate to the mass of the stabilizer is (1.1-2.5):1.

[0056] In one embodiment, the mass ratio of the sum of the masses of the hydrolyzed sodium hyaluronate and the yeast / rice fermentation product filtrate to the stabilizer is (1.625-2):1. By controlling the mass ratio within this range, the intermolecular force can be increased, and the molecules can be adsorbed and cross-linked with each other to effectively improve the stability of the system. At the same time, the surface tension can be reduced, and the permeability and wettability of the liquid can be improved within this range. The synergy of the three can be better promoted, and the penetration-promoting effect is further improved.

[0057] One embodiment of the present application provides a method for preparing a penetration-enhancing composition, comprising the following steps:

[0058] The hydrolyzed sodium hyaluronate, a stabilizer, a yeast / rice fermentation product filtrate and a solvent are uniformly mixed to obtain a penetration-enhancing composition.

[0059] One embodiment of the present application provides a use of a penetration-enhancing composition in the preparation of cosmetics.

[0060] In one embodiment, the cosmetic is in the form of a lotion, emulsion, cream, gel, mask or essence.

[0167] Test Case

[0168] 1. With retinol as the target active ingredient, the compositions of the examples and comparative examples were mixed with retinol at a ratio of 95:5 to prepare test substances, thereby examining the penetration-enhancing effects of the penetration-enhancing compositions of the examples and comparative examples.

[0169] The suckling pig skin-Franzcell permeation diffusion cell test was used (the instrument was a TK-type transdermal absorption tester, and the instrument operation method can be referred to), with reference to the national standard GBT27818-2011.

[0170] The specific method is as follows: remove the hair and subcutaneous tissue from fresh pig back skin, clean it, dry it, and cut it into appropriate sizes for later use. Fix the pig back skin between the supply chamber and the receiving chamber of the TK type transdermal absorption tester. The receiving liquid is an isotonic PBS buffer solution. The test liquids are the compositions of the embodiment and the comparative example respectively. Five groups of samples are tested in parallel, and the average value is taken. The transdermal test is performed in a 37°C circulating water bath. Take 0.5mL of sample at 4h and 12h after the start of the test, and add 0.5mL of PBS after sampling. The sample is filtered through a 0.22μm filter membrane and used as a test sample. The diffusion percentage of retinol in the 4h and 12h samples is detected and calculated respectively.

[0171] Among them, the content of retinol was tested using the determination method of "Guangdong Cosmetics Association Group Standard T / GDCA 005-2021 Retinol, Retinol Acetate, Retinol Palmitate, and Hydroxypinacolone Retinoate in Cosmetics".

[0172] Table 1

[0173]

[0174]

[0175] As can be seen from Table 1, the penetration-enhancing composition of the present invention has an excellent penetration-enhancing effect and can effectively promote the penetration of active ingredients.

[0176] By comparing Example 1 with Comparative Examples 3 to 10, it can be seen that, under the system of the present invention, the hydrolyzed sodium hyaluronate, the stabilizer, and the yeast / rice fermentation product filtrate have a significant synergistic effect in promoting penetration. The lack of any one of them or the replacement of any one of them with other penetration enhancers results in a significant decrease in the penetration promoting effect.

[0177] By comparing Example 1 with Comparative Examples 11 to 12, it can be seen that the present invention significantly improves the penetration-enhancing effect by adopting decapeptide-4, soybean lecithin, sodium carboxymethyl cellulose, and polyethylene glycol surfactants in a mass ratio of (0.05 to 0.4): (0.05 to 0.4): (0.08 to 0.5): 1.

[0178] By comparing Examples 1 to 5 with Comparative Examples 1 to 2, it can be seen that the present invention controls the amount of each raw material to: 0.5 to 8 parts of hydrolyzed sodium hyaluronate, 5 to 20 parts of stabilizer, 12 to 25 parts of yeast / rice fermentation product filtrate, and 40 to 80 parts of solvent; the compatibility of each raw material is better, and the penetration-enhancing effect is significantly improved.

[0179] Comparing Examples 1 to 3 with Examples 4 to 5, it can be seen that the present invention further improves the penetration-enhancing effect by controlling the amount of each raw material to: 2 to 6 parts of hydrolyzed sodium hyaluronate, 12 to 20 parts of stabilizer, 18 to 22 parts of yeast / rice fermentation product filtrate, and 56 to 64 parts of solvent.

[0180] Comparing Example 1 with Examples 6 to 8, it can be seen that the present invention further improves the penetration-enhancing effect by controlling the mass ratio of the sum of the mass of hydrolyzed sodium hyaluronate and the yeast / rice fermentation product filtrate to the mass ratio of the stabilizer to (1.625 to 2):1.

[0181] Comparing Example 1 with Examples 9 to 12, it can be seen that the present invention further improves the penetration-enhancing effect by adopting decapeptide-4, soybean lecithin, sodium carboxymethyl cellulose, and polyethylene glycol surfactants in a mass ratio of (0.08 to 0.2): (0.08 to 0.2): (0.1 to 0.3): 1.

[0182] Comparing Example 1 with Examples 13 to 15, it can be seen that the present invention further improves the penetration-enhancing effect by using sodium carboxymethyl cellulose having a weight-average molecular weight of 90,500 to 250,000 and a viscosity of 25 to 100 mPa.s in a 2 wt% aqueous solution at 25°C.

[0183] Comparing Examples 1, 17, and 18 with Examples 19 to 20, it can be seen that the use of isononyl isononanoate, dimethyl isosorbide, and alcohol solvents in a mass ratio of (0.1 to 0.4): (0.2 to 0.5): 1 further improves the penetration-enhancing effect.

[0184] 2. Stability test

[0185] The penetration-enhancing compositions of the Examples and Comparative Examples were subjected to stability tests. The heat resistance test involved standing at 48°C for three months and observing their appearance, color, and odor. The cold resistance test involved standing at -18°C for three months and observing their appearance, color, and odor. The room temperature test involved standing at 25°C for three months and observing their appearance, color, and odor. The hot and cold cycling test involved storing at 45°C, room temperature, and -18°C for 24 hours each, for 10 cycles, and observing their appearance, color, and odor. The test results are shown in Table 2.

[0186] Table 2

[0187]

[0188]

[0189] As can be seen from Table 2, the penetration-enhancing composition of the present invention has excellent stability, wherein the stabilizer is the key to achieving stability. The use of the stabilizer of the present invention significantly improves the stabilization effect. If the raw material ratio of the stabilizer is changed, the high temperature stability and cyclic stability cannot be achieved.

[0190] 3. Irritation test

[0191] The test was conducted according to the method of SNT 2329-2009, and the results were evaluated using the stimulation scoring method.

[0192] The specific scores are shown in Table 3, and the evaluation results are shown in Table 4.
