Description

Technical Field

[0001] The invention relates to the technical field of biomedical materials, in particular to a double-fermented pachydermogen liposome and a preparation method and cosmetics thereof. Background Art

[0002] Double fermented thick skin factor (named double fermented thick skin factor LAB POR) mainly contains galactosyl yeast fermentation broth, lactic acid bacteria NP, and glycyrrhizic acid. Lactobacillus NP is a product obtained from the lysate produced by the fermentation of Lactococcus lactis. It contains all the active ingredients of the bacteria itself and the fermentation process, and has a good anti-aging effect. Lactic acid bacteria fermentation technology can convert large molecular functional substances into small molecules, maximize the retention of active substances, and promote the direct absorption of nutrients by the skin. Lactic acid bacteria lysate can improve the quality and diversity of skin microorganisms. At the same time, the polypeptide substances such as lactobacillus contained in it can adhere to the skin surface and act as an antibacterial barrier. The amino acids, polysaccharides, B vitamins, etc. in the lactic acid bacteria lysate can enhance the metabolism of the stratum corneum, remove free radicals, and activate the body's repair properties. The lactic acid and sodium lactate contained in the lactic acid bacteria lysate can form an acid mask, maintaining the skin at a healthy weakly acidic pH to improve the sub-healthy state of the skin. In addition, the lactic acid bacteria fermentation lysate can promote the synthesis of collagen and hyaluronic acid, and has a long-lasting and deep moisturizing effect on the skin.

[0003] Galactose yeast fermentation liquid is rich in bio-oligosaccharides, amino acids, organic acids, vitamins and other ingredients, which can improve skin barrier function and cell vitality, making the skin more delicate and plump. Long-term use has significant improvement effects.

[0004] Liposomes are a new type of drug carrier, which is composed of phospholipids and other amphiphilic substances dispersed in water to form one or more concentric liposome bimolecular membranes encapsulating ultra-microscopic spherical drug carriers. Liposomes can encapsulate water-soluble or fat-soluble drugs. Their structure is similar to biological membranes, so they can enhance the degree of entry of active ingredients into the stratum corneum or epidermal lipids, increase the accumulation of active ingredients in the local skin, improve bioavailability, and have a sustained release effect. Glycyrrhetinic acid is a pentacyclic triterpenoid saponin extracted from the plant licorice, which has anti-inflammatory, anti-allergic and antibacterial effects. Glycyrrhetinic acid has an amphiphilic structural characteristic similar to that of surfactants. It can interact with cholesterol or phospholipids on the cell membrane, change the fluidity of lipids, increase the permeability of the cell membrane and the ability of drugs to cross the membrane. The hydrophilicity of glycyrrhetinic acid comes from the two glucuronic acids and one carboxyl group in its structure. It has poor water solubility and is greatly affected by pH, which limits its scope of application.

[0005] Supramolecular eutectic solvents are transparent solutions formed by mixing two or more different hydrogen bond acceptors and hydrogen bond donors at a certain molar ratio at a certain temperature. Their properties are similar to those of ionic liquids. Eutectic treatment can reduce the irritation of raw materials, improve solubility and stability, and enhance functionality and permeability.

[0006] However, the double-fermented thick skin factor LAB POR has the disadvantages of easy sedimentation and low transdermal efficiency, which limits its application.

DETAILED DESCRIPTION

[0037] The embodiments of the present invention will be described in detail below in conjunction with the embodiments and examples, but those skilled in the art will understand that the following embodiments and examples are only used to illustrate the present invention and should not be considered to limit the scope of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] The first aspect of the present invention provides a double fermented pachydermogen liposome, comprising alkaloids, double fermented pachydermogen, phospholipids and short chain fatty alcohols;

[0039] The double fermentation thick skin factor comprises galactosyl yeast fermentation liquid, lactic acid bacteria NP and glycyrrhizic acid.

[0040] The double fermented pachyderm factor liposome provided by the present invention has excellent anti-aging and anti-aging effects, can significantly improve cell vitality, and enhance skin barrier. It is made into a liposome form, and glycyrrhetinic acid and matrine in the double fermented pachyderm factor are used to form a supramolecular eutectic, which not only helps the transdermal absorption of the double fermented pachyderm factor, but also can reduce the irritation of the double fermented pachyderm factor to make it milder. The double fermented pachyderm factor liposome has the dual advantages of a supramolecular eutectic solvent and a liposome, efficiently promotes the double fermented pachyderm factor to enter the skin, improves the skin retention rate, and effectively improves the local treatment effect to exert its anti-aging and anti-aging effects.

[0041] In the double fermented thick skin factor, glycyrrhetinic acid can participate in the formation of supramolecular eutectics, which can increase the stability of the active substance and reduce the pH to make the active ingredient more mild; in addition, glycyrrhetinic acid is amphiphilic and can be embedded in the arranged phosphatidylcholine to participate in the construction of liposomes, which enables the liposomes to remain stable for a long time in the temperature range of -20°C to 50°C. In the present invention, the supramolecular eutectics formed by glycyrrhetinic acid are embedded or partially embedded in the liposome membrane, which can cooperate with the liposome to exert the penetration ability, more efficiently promote the double fermented thick skin factor LAB POR to enter the skin, improve the skin residence rate, and effectively improve the local treatment effect to exert its anti-aging and anti-aging effects.

[0103] Table 1

[0104]

[0105]

[0106] Test Example 2

[0107] The liposomes or emulsions obtained in the examples and comparative examples were compared in terms of penetration ability. The specific method is as follows:

[0108] Using glycyrrhetinic acid as a standard, weigh 50 g of liposomes or emulsions, then add 0.8 g of %SIMULGEL FL and 49.2 g of water in sequence and stir evenly at 50°C to obtain a test sample solution.

[0109] Skin retention rate test: The skin permeation test is carried out according to the in vitro permeation test guidelines stipulated by the OECD / OCDE European OECD Chemical Testing Guidelines.

[0110] The retention data are recorded in Table 2.

[0111] Table 2

[0112]

[0113] Comparative analysis of Table 1 and Table 2 shows that glycyrrhetinic acid is used as the active ingredient calibration component to explore the effect of changes in the content of the double fermented thick skin factor LAB POR on the skin retention and stability. According to the results of Example 1, Example 4, and Example 6, as the content of the double fermented thick skin factor LAB POR decreases, its stability does not change significantly. Example 6 appears slightly turbid because the decrease in the content of glycyrrhetinic acid causes the pH of the system to change, which in turn affects the stability of the liposomes; the skin retention of glycyrrhetinic acid decreases because as the content of glycyrrhetinic acid decreases, the number of eutectic molecules formed decreases, and the penetration-enhancing effect becomes worse. In Examples 1, 5 and 7, as the content of the double fermented thick skin factor LAB POR gradually increased, its stability decreased. This is because the increase in active ingredients caused the generation of two unstable factors. First, as the glycyrrhetinic acid increased, matrine was not sufficient to combine with all the glycyrrhetinic acid, and part of the glycyrrhetinic acid existed in a free state and then crystallization occurred; second, excessive double fermented thick skin factor LAB POR resulted in the inability of liposomes to completely encapsulate it, and demulsification occurred over time, and the skin retention amount of glycyrrhetinic acid also decreased accordingly.

[0114] Through the analysis of the skin retention amount of the comparative examples and the embodiments, it can be seen that both the co-crystal solvent and the liposome can promote the transdermal ability of glycyrrhetinic acid; the embodiment can significantly enhance the ability of glycyrrhetinic acid to penetrate the skin by embedding the co-crystal into the liposome, so the combination of the co-crystal and the liposome can exert a synergistic penetration-enhancing effect.

[0115] The glycyrrhetinic acid contained in the double fermented thick skin factor LAB POR can form a supramolecular eutectic with matrine, which can cooperate with the liposomes formed by it to promote the transdermal absorption of active ingredients. According to Examples 1-3, it can be known that only when glycyrrhetinic acid and matrine are combined in an appropriate ratio can they have a good penetration-promoting effect and maintain high stability at the same time. The low content of matrine has little effect on the particle size of the liposome, but it will cause its stability to deteriorate. This is because when the content of matrine is low, it cannot form a eutectic with more glycyrrhetinic acid, which leads to more crystallization in the double fermented thick skin factor LAB POR composition, destroying the structure of the liposome, resulting in poor transdermal performance; too high a content of matrine will also lead to poor stability. The change in the pH conditions of the environment caused by the high content of matrine is the main factor affecting stability. Due to the decrease in stability, the retention amount of the skin becomes lower.
