Description

A cosmetic composition containing glutathione with excellent formulation stability and deodorizing effect

[0001] The present invention relates to a cosmetic composition containing glutathione as an active ingredient, and specifically, to a cosmetic composition that exhibits excellent deodorizing efficacy for glutathione through a combination of glutathione, fullerene, and polyacrylate crosspolymer, and has excellent formulation stability and usability.

[0002] Glutathione is a compound composed of three peptides: glutamate, cysteine, and glycine. It not only acts in various enzymatic or non-enzymatic detoxification mechanisms but also possesses free radical scavenging ability, enabling it to protect cells from reactive oxygen species and xenobiotics. Furthermore, glutathione is naturally produced in the body and performs useful roles such as detoxification and immune functions.

[0003] Recently, health foods containing glutathione have become increasingly popular, and they are also being actively utilized in the beauty industry as they can help improve skin, such as whitening and anti-aging.

[0004] However, despite these advantages, glutathione has limitations in being applied as a cosmetic ingredient because users are repulsed by the unpleasant odor caused by the thiol groups within the compound.

[0005] Meanwhile, fullerenes have a high surface area and can effectively adsorb various odor molecules, thereby exhibiting deodorizing efficacy. However, despite these characteristics, fullerenes are difficult to stabilize within a composition, making it difficult to formulate them at a concentration sufficient to fully exert their efficacy in a product. Additionally, fullerenes may clump or aggregate in specific areas within the composition, and such aggregation can cause a decrease in user experience when the composition is applied to the skin.

[0006] Accordingly, the inventors continued research on a method to effectively remove the odor of glutathione while increasing formulation stability, and as a result, developed a cosmetic composition with excellent deodorizing effect on glutathione and stabilized formulation through a combination of glutathione, fullerene, and polyacrylate crosspolymer.

[0007] The present invention aims to provide a cosmetic composition that has excellent deodorizing effect on glutathione and high formulation stability.

[0008] The technical problems of the present invention are not limited to those mentioned above, and other unmentioned technical problems will be clearly understood by those skilled in the art from the description below.

[0009] According to an embodiment of the present invention, a cosmetic composition having excellent stability and deodorizing effect is provided, characterized by containing glutathione and including fullerene and a polyacrylate crosspolymer.

[0010] The cosmetic composition according to the present invention is characterized by excellent skin improvement effects, such as preventing skin aging and providing a whitening effect, by including glutathione as an active ingredient. In addition, even though glutathione is included as an active ingredient, it has an excellent deodorizing effect on glutathione, which can reduce the unpleasantness caused by the characteristic odor of glutathione.

[0011] In addition, the formulation of the composition is stably formed, and its good spreadability allows for an excellent user experience.

[0012] A brief description of each drawing is provided to help to better understand the drawings cited in the detailed description of the invention.

[0018] According to an embodiment of the present invention, a cosmetic composition having excellent stability and deodorizing effect is provided, characterized by containing glutathione and including fullerene and a polyacrylate crosspolymer.

[0019] The glutathione may be included in an amount of 1 to 5 weight percent based on the total weight of the cosmetic composition.

[0020] The above fullerene may be included in an amount of 0.01 to 1 weight% based on the total weight of the cosmetic composition.

[0021] The glutathione and fullerene may be included in a weight ratio of 1:0.002 to 0.2.

[0022] The above polyacrylate crosspolymer may be included in an amount of 0.01 to 0.5 weight percent based on the total weight of the cosmetic composition.

[0023] The glutathione and polyacrylate crosspolymer may be included in a weight ratio of 1:0.002 to 0.2.

[0024] The glutathione, fullerene, and polyacrylate crosspolymer may be included in a weight ratio of 1:0.002 to 0.2:0.002 to 0.2.

[0025] The combined weight of the glutathione and fullerene and the polyacrylate crosspolymer may be included in a weight ratio of 1:0.0015 to 0.2.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by a skilled expert in the art to which the present invention pertains. In general, the nomenclature used herein is well known and commonly used in the art. Furthermore, in describing embodiments of the present invention, detailed descriptions of related known components or functions are omitted if it is determined that such detailed descriptions would hinder understanding of the embodiments of the present invention. Additionally, while embodiments of the present invention will be described below, the technical concept of the present invention is not limited or restricted thereto and can be modified and implemented in various ways by those skilled in the art.

[0027] In this specification, when a part is described as including a certain component, it means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. In this specification, the term "and / or" includes a combination of a plurality of related items or any one of a plurality of related items.

[0028]

[0029] According to an embodiment of the present invention, a cosmetic composition having excellent stability and a deodorizing effect of glutathione is provided. The cosmetic composition can stably contain glutathione within the formulation, thereby effectively exhibiting the efficacy (antioxidant, whitening) of the glutathione component, and also has the effect of improving the user experience by reducing the inherent odor of glutathione.

[0030] The “glutathione (Glutathione, C12)” used in the present invention 10 H 17“N3O6S” is a water-soluble peptide compound with a molecular weight of approximately 307.3235 g / mol, composed of three peptides (tripeptides): glutamate, cysteine, and glycine. Glutathione is an antioxidant present in the body that can effectively remove in vivo radicals by reversibly reacting with in vivo antioxidants such as ascorbic acid (vitamin C) and tocopherol (vitamin E), and it has been reported to have a skin whitening effect as a major function.

[0031] In one embodiment, the glutathione may be included in an amount of 1 to 5 weight percent based on the total weight of the cosmetic composition. If the glutathione is included in an amount of less than 1 weight percent based on the total weight of the cosmetic composition, the skin-improving efficacy of the glutathione is insufficient, and if it is included in an amount of more than 5 weight percent, the glutathione is difficult to dissolve, so the formulation cannot be realized. However, it is not limited thereto.

[0032] A cosmetic composition according to one embodiment of the present invention comprises fullerenes and a polyacrylate crosspolymer together with glutathione. The inventors combined fullerenes and a polyacrylate crosspolymer with glutathione to ensure that the fullerene component is stably dispersed within the composition. Accordingly, fullerenes are enabled to effectively remove the characteristic odor of glutathione.

[0033] Fullerenes are carbon allotropes, such as graphite or diamond, and are a collective term for molecules in which carbon atoms are arranged in spherical, ellipsoidal, or cylindrical shapes. Fullerenes can be represented by any one of the chemical formulas C60, C70, C76, C78, ​​and C84, and can have carbon rings in which carbon atoms are arranged in a pentagonal or hexagonal configuration.

[0034] In one embodiment, the fullerene may be C60. C60 is formed by 60 carbon atoms bonded together in a soccer ball shape and is also called buckminsterfullerene. Fullerene having this structure has a high surface area and can effectively adsorb molecules that cause various odors or bad smells, so it can be used as an active ingredient to impart deodorizing efficacy.

[0035] In one embodiment, the fullerene may be included in an amount of 0.01 to 1% by weight based on the total weight of the cosmetic composition. If the fullerene is included in an amount of less than 0.01% by weight based on the total weight of the cosmetic composition, the deodorizing effect of glutathione is insufficient, and if it is included in an amount of more than 1% by weight, the fullerene is difficult to dissolve, so the formulation cannot be formed stably. However, it is not limited thereto.

[0036] In one embodiment, glutathione and fullerene may be included in a weight ratio of 1:0.002 to 0.2. When glutathione and fullerene are included in the above weight ratio, the deodorizing effect of glutathione can be sufficiently exhibited.

[0037] As a dispersant for stably dispersing fullerene, which imparts deodorizing efficacy in the present invention, within the composition, a polyacrylate crosspolymer may be included. The polyacrylate crosspolymer, acting as an emulsifier for forming emulsion particles, can contribute to stably dispersing fullerene within the formulation so that the cosmetic composition forms sufficient viscosity and the deodorizing efficacy of fullerene is fully exhibited.

[0038] In one embodiment, the polyacrylate crosspolymer may be included in an amount of 0.01 to 0.5 weight% based on the total weight of the cosmetic composition. If the polyacrylate crosspolymer is included in an amount of less than 0.01 weight% based on the total weight of the cosmetic composition, the fullerene is not sufficiently dissolved, making it difficult to form the composition; if it is included in an amount exceeding 0.5 weight%, the viscosity becomes excessively high, causing slippage and potentially degrading the usability of the cosmetic composition. However, it is not limited thereto.

[0039] In one embodiment, glutathione and polyacrylate crosspolymer may be included in a weight ratio of 1:0.002 to 0.2. When the glutathione and polyacrylate crosspolymer are included in the above weight ratio, the formulation of the composition can be stably formed.

[0040] In one embodiment, glutathione, fullerene, and polyacrylate crosspolymer may be included in a weight ratio of 1:0.002 to 0.2:0.002 to 0.2. When the glutathione, fullerene, and polyacrylate crosspolymer are included in such a weight ratio, the formulation of the composition is stably realized, and the deodorizing efficacy of glutathione can be excellently exhibited.

[0041] In one embodiment, the combined weight of the glutathione and fullerene and the polyacrylate crosspolymer may be included in a weight ratio of 1:0.0015 to 0.2. When the combined weight of the glutathione and fullerene and the polyacrylate crosspolymer are included in such a weight ratio, the formulation of the composition is stably realized, and the deodorizing effect on glutathione is excellent, thereby reducing the unpleasantness caused by the characteristic odor of glutathione.

[0042] In one embodiment, the cosmetic composition of the present invention may additionally include a preservative, a moisturizer, or a functional ingredient in addition to the main ingredient.

[0043] The above preservative is used to enhance the effect of preservation, and for example, at least one of ethylhexylglycerin, 1,2-hexanediol, caprylyl glycol, phenoxyethanol, and glyceryl caprylate may be used, but is not limited thereto, and any preservative generally used in the industry may be appropriately selected without limitation.

[0044] The above moisturizer is used to enhance the protective and moisturizing effects of the skin, and at least one of propanediol, 2,3-butanediol, propylene glycol, butyloctyl salicylate, caprylyl methicone, butylene glycol, pentylene glycol, glycerin, niacinamide, and dipotassium glycyrrhizate may be used, but is not limited thereto, and any moisturizer that can be generally used in the industry may be appropriately selected without limitation.

[0045] The above functional ingredients may be added by mixing various ingredients according to the purpose of the cosmetic composition, and include, for example, all of the following: wrinkle improvement agents, whitening functional ingredients, pigmentation functional ingredients, skin soothing functional ingredients, and sebum or pore management functional ingredients.

[0046] In addition, the cosmetic composition of the present invention may further include other active ingredients contained in conventional cosmetic compositions, such as antioxidants, neutralizing agents, stabilizers, vitamins, proteins, anti-fading agents, chelating agents, and other additives, within a range that does not impair the effects of the present invention. The amounts of the above ingredients are not particularly limited and can be easily selected by a person skilled in the art within a range that does not impair the purpose and effects of the present invention.

[0047] The cosmetic composition of the present invention may be provided in formulations commonly manufactured in the art. For example, it may be formulated into emulsion formulations of the type of oil in water (O / W), water in oil (W / O), or water in oil in water (W / O / W). However, it is not limited thereto, and the composition may also be provided in various formulations such as solution, suspension, emulsion, solid, oil, powder, paste, or foam aerosol, mist, etc.

[0048] The cosmetic composition according to the present invention may be in a liquid, lotion, cream, aerosol, solid, or solid form including powder, and preferably may be a lotion composition. In the present invention, the formulation of the cosmetic composition may include a solution, emulsion, gel, cream, suspension, or paste formulation, but is not limited thereto.

[0049]

[0050] In the following, examples and experimental examples are presented to further explain the present invention in more detail, but the present invention is not limited thereto.

[0051]

[0052] Experimental Example 1: Comparative experiment with the addition of fullerene and polyacrylate crosspolymer

[0053] A cosmetic composition was prepared by combining a glutathione component with fullerene and a polyacrylate crosspolymer, and the efficacy of the formulation was evaluated. In addition, to investigate the effects of fullerene and the polyacrylate crosspolymer on the stability of the composition and the deodorizing effect of glutathione, a cosmetic composition of a comparative example was prepared by excluding some of the fullerene and polyacrylate crosspolymer components, and the efficacy of the formulation was evaluated. The specific manufacturing method is as follows.

[0054]

[0055] (1) Preparation of cosmetic composition

[0056] Cosmetic compositions of Example 1 and Comparative Examples 1 and 2 according to the present invention were prepared using the ingredients listed in Table 1 below. Specifically, Example 1 is a cosmetic composition containing both fullerene (C60) and polyacrylate crosspolymer in the glutathione component. On the other hand, Comparative Example 1 is a cosmetic composition containing polyacrylate crosspolymer but not fullerene, and Comparative Example 2 is a cosmetic composition containing fullerene but not polyacrylate crosspolymer.

[0057] In Table 1 below, the unit of each component content is weight %.

[0058]

[0059]

[0060] The specific manufacturing method is as follows. First, glutathione, fullerene, and polyacrylate crosspolymer were dissolved in purified water using an AGI MIXER at room temperature, and then a moisturizer and a preservative were added to prepare a cosmetic composition according to the example and comparative example.

[0061]

[0062] (2) Formulation stability evaluation

[0063] The formulation stability of the cosmetic compositions prepared according to Example 1 and Comparative Examples 1 and 2 above was evaluated. The specific experimental methods are as follows.

[0064] Specifically, the cosmetic composition was stored for one week under repeated cycles of high temperature (45 ℃), room temperature (25 ℃), and low temperature (-5 ℃), followed by cooling from high to room and low temperatures and then heating again from low to room and high temperatures. Afterward, it was measured whether the viscosity and formulation were still maintained as they were immediately after manufacturing. If formulation stability was not maintained under any of the four temperature conditions (high temperature, room temperature, low temperature, and cooling / heating), it was judged as unsatisfactory. Stability was evaluated as O if the composition stably formed a formulation, and as X if the formulation was not realized or if the viscosity was excessively high, resulting in a burning or sticky finish. The measurement results are shown in Table 2 below. Additionally, a photograph of the cosmetic composition of Example 1 is shown in Figure 1.

[0065]

[0066]

[0067] As shown in Table 2 and Figure 1 above, it was confirmed that the cosmetic composition of Example 1 had a stable formulation and excellent stability.

[0068] Meanwhile, the cosmetic composition of Comparative Example 1, which contains only polyacrylate crosspolymer among fullerene and polyacrylate crosspolymer, was found to have a stable formulation, but had an excessively high viscosity compared to Example 1. On the other hand, the cosmetic composition of Comparative Example 2, which contains only fullerene and does not contain polyacrylate crosspolymer, was found to have a stable formulation.

[0069]

[0070] (3) Evaluation of deodorizing efficacy

[0071] The deodorizing efficacy of the cosmetic compositions of the examples and comparative examples was evaluated, and the results are shown in Table 3 below. The specific experimental methods are as follows.

[0072] The concentration of glutathione immediately after the preparation of the above cosmetic composition and the concentration of glutathione after 60 minutes were measured via HPLC analysis to calculate the odor reduction rate (deodorization rate). In addition, the odor intensity before and after deodorization was compared at a distance of within 10 cm, and O was indicated if deodorizing efficacy was present, and X was indicated if it was absent. The measurement results are shown in Table 3 below.

[0073]

[0074]

[0075] According to Table 3 above, the composition of Example 1, prepared using fullerene and polyacrylate crosspolymer, was confirmed to have an excellent deodorizing effect on glutathione. Meanwhile, Comparative Example 1, which contains only polyacrylate crosspolymer among fullerene and polyacrylate crosspolymer, showed that the characteristic odor of glutathione persisted and had almost no deodorizing efficacy. The cosmetic composition of Comparative Example 2, which contains only fullerene and does not contain polyacrylate crosspolymer, showed improved deodorizing efficacy compared to Comparative Example 1, but was confirmed to be significantly lower than Example 1.

[0076]

[0077] Through the above experiment, it was confirmed that when a polyacrylate crosspolymer is included together with fullerene, the fullerene, which imparts the deodorizing efficacy of glutathione, is stably dispersed within the composition, thereby forming a formulation of the composition and exhibiting an excellent deodorizing effect. Therefore, it was confirmed that including both fullerene and polyacrylate crosspolymer components is an important factor in the formulation formation, stability, and deodorizing efficacy of the cosmetic composition of the present invention.

[0078]

[0079] Experimental Example 2: Comparative experiment according to change in the composition of polyacrylate crosspolymer

[0080] To investigate the effect of polyacrylate crosspolymer on the stability of the composition and the deodorizing effect of glutathione, cosmetic compositions of comparative examples were prepared by changing the polyacrylate crosspolymer to another polymer component, and the efficacy of the formulations was evaluated. The specific manufacturing method is as follows.

[0081]

[0082] (1) Preparation of cosmetic composition

[0083] Cosmetic compositions of Comparative Examples 3 and 4 according to the present invention were prepared using the ingredients listed in Table 4 below. Here, the remaining ingredients and their contents, excluding the core ingredients, are the same as those in Example 1. Specifically, Comparative Examples 3 and 4 include fullerene but replace polyacrylate crosspolymer with other ingredients. In Table 4 below, the unit for the content of each ingredient is weight%.

[0084]

[0085]

[0086] (2) Formulation stability evaluation

[0087] For the cosmetic compositions prepared according to Comparative Examples 3 and 4, formulation stability was evaluated in the same manner as performed in Experimental Example 1, and the viscosity of the compositions was measured. The evaluation results are summarized in Table 5 below. In addition, photographs of the cosmetic compositions of Comparative Examples 3 and 4 are shown in Figure 2.

[0088]

[0089]

[0090] As shown in Table 5 and Figure 2 above, meanwhile, the cosmetic composition of Comparative Example 3, which contains a fullerene component and includes sodium polyacrylate starch instead of polyacrylate crosspolymer, was found to have excessively high viscosity and low formulation stability. In addition, an agglutinous appearance was achieved, and a phenomenon of slipping occurred when applied to the skin.

[0091] It was confirmed that the cosmetic composition of Comparative Example 4, which contains fullerene components and includes polyacrylate-13 instead of polyacrylate crosspolymer, also exhibited high viscosity, low formulation stability, an agglutinous appearance, and a sticky finish.

[0092]

[0093] (3) Evaluation of deodorizing efficacy

[0094] The deodorizing efficacy of the cosmetic compositions prepared according to Comparative Examples 3 and 4 was evaluated in the same manner as that performed in Experimental Example 1. The evaluation results are summarized in Table 6 below.

[0095]

[0096]

[0097] According to Table 6 above, in the case of Comparative Example 3, which contains sodium polyacrylate starch instead of polyacrylate crosspolymer, it was confirmed that the deodorizing efficacy of glutathione was similar to that of the composition of Example 1. In addition, in the case of Comparative Example 4, which contains polyacrylate-13 instead of polyacrylate crosspolymer, it was confirmed that the deodorizing efficacy of glutathione was lower than that of the example.

[0098]

[0099] Through the above experiment, it was confirmed that the polyacrylate crosspolymer component affects the stability of the composition and the deodorizing efficacy of glutathione. Therefore, it was confirmed that including both fullerene and polyacrylate crosspolymer components is an important factor in the formulation formation, stability, and deodorizing efficacy of glutathione of the cosmetic composition of the present invention.

[0100]

[0101] Experimental Example 3: Comparative experiment according to glutathione, fullerene, and polyacrylate crosspolymer content

[0102] To investigate the effects of the content of glutathione, fullerene, and polyacrylate crosspolymer on formulation stability and deodorizing efficacy, cosmetic compositions of examples and comparative examples were prepared by varying the added content of glutathione, fullerene, and polyacrylate crosspolymer, and the efficacy of the formulations was evaluated. The specific manufacturing method is as follows.

[0103]

[0104] (1) Preparation of cosmetic composition

[0105] To evaluate the efficacy of cosmetic compositions according to the content of the key ingredients listed in Table 7 below, cosmetic compositions of Examples 2 and Comparative Examples 5 and 6 were prepared by changing the content of glutathione (A) based on Example 1. Additionally, cosmetic compositions of Examples 3 and 4, and Comparative Examples 7 and 8 of the composition according to the present invention were prepared by changing the content of fullerene (B). Furthermore, cosmetic compositions of Examples 5 and 6, and Comparative Examples 9 and 10 of the composition according to the present invention were prepared by changing the content of polyacrylate crosspolymer (C). Here, the remaining ingredients and their contents, excluding the key ingredients, are the same as in Example 1. In Table 7 below, the unit of the content of each ingredient is weight%.

[0106]

[0107]

[0108] (2) Formulation stability evaluation

[0109] For the cosmetic compositions prepared according to Examples 2 to 6 and Comparative Examples 5 to 10, formulation stability evaluation was conducted in the same manner as performed in Experimental Example 1, and the viscosity of the compositions was measured. The evaluation results are summarized in Table 8 below. In addition, photographs of the cosmetic compositions of Comparative Examples 5 and 6 are shown in FIG. 3, photographs of the cosmetic compositions of Comparative Examples 7 and 8 are shown in FIG. 4, and photographs of the cosmetic compositions of Comparative Examples 9 and 10 are shown in FIG. 5.

[0110]

[0111]

[0112] As shown in Table 8 and Figure 3 above, it was confirmed that the cosmetic composition of Example 2 formed a formulation in which glutathione was stably and evenly dispersed within the composition as glutathione was included in appropriate weight and weight ratios. On the other hand, Comparative Example 5, which contained a small amount of glutathione compared to the example, was found to have a formulation but exhibited lower viscosity compared to Example 1. Conversely, Comparative Example 6, which contained an excessive amount of glutathione compared to the example, was not formed and viscosity could not be measured.

[0113] As shown in Table 8 and Figure 4 above, it was confirmed that the cosmetic compositions of Examples 3 and 4 had excellent formulation stability because the fullerene was stably and evenly dispersed within the composition as the fullerene was included in appropriate weight and weight ratios. In addition, it was confirmed that the formulation stability of Comparative Example 7, which contained a small amount of fullerene compared to the examples, was not poor, while it was confirmed that Comparative Example 8, which contained an excessive amount of fullerene compared to the examples, had a separation of formulations because the fullerene was not sufficiently dissolved.

[0114] As shown in Table 8 and Figure 5 above, it was confirmed that the cosmetic compositions of Examples 5 and 6 contained polyacrylate crosspolymer in appropriate weight and weight ratios, so fullerene was stably and evenly dispersed within the composition, resulting in appropriate viscosity and excellent formulation stability. On the other hand, the composition of Comparative Example 9, which contained a small amount of polyacrylate crosspolymer compared to the examples, did not form a proper formulation, and therefore its viscosity could not be measured. In addition, Comparative Example 10, which contained an excessive amount of polyacrylate crosspolymer compared to the examples, was found to exhibit excessively high viscosity due to the excessive amount of polyacrylate crosspolymer, and a phenomenon of slipping occurred when applied to the skin.

[0115]

[0116] (3) Evaluation of deodorizing efficacy

[0117] The deodorizing efficacy of the cosmetic compositions prepared according to Examples 2 to 6, Comparative Example 5, and Comparative Example 10 was evaluated in the same manner as performed in Experimental Example 1. The evaluation results are summarized in Table 9 below.

[0118]

[0119]

[0120] According to Table 9 above, Examples 2 to 6, which contain glutathione, fullerene, and polyacrylate crosspolymer in appropriate weights and weight ratios, were confirmed to exhibit excellent deodorizing efficacy.

[0121] Meanwhile, it was confirmed that the composition of Comparative Example 7, which contained a small amount of fullerene compared to the Example, showed a very low glutathione deodorizing effect. Additionally, it was confirmed that Comparative Example 10, which contained an excess amount of polyacrylate crosspolymer compared to the Example, exhibited glutathione deodorizing efficacy values ​​similar to those of the Example.

[0122] The cosmetic compositions of Comparative Examples 5, 6, 8, and 9 could not have their deodorizing efficacy measured because the formulation of the composition was not realized.

[0123]

[0124] Through this, it was confirmed that in order to simultaneously secure the formulation stability and deodorizing effect intended in the present invention, it is necessary to appropriately maintain the weight and weight ratio of glutathione, fullerene, and polyacrylate crosspolymer, respectively, when preparing a glutathione-containing cosmetic composition.

[0125]
