Abstract
Description
[Technical Field]
[0001] The present invention relates to cosmetic compositions comprising a solid phase polymer with improved solubility. [Background technology]
[0002] Generally, in cosmetics, polymers such as hyaluronic acid or collagen, and functional ingredients such as vitamins and antioxidants have been used as active ingredients for skin improvement, such as whitening, wrinkle reduction, increased skin elasticity, moisturizing, promoting skin regeneration, and removing harmful oxygen. However, these active ingredients have been limited in their use in cosmetics because they may increase the viscosity of the cosmetic, react with other ingredients, or be easily destroyed by oxidation when present in an aqueous solution or in contact with water through exposure to light or air, or change color or fragrance. To solve these problems and maximize the skin improvement efficacy by stabilizing the active ingredients, a method of formulating them into a powder-type solid-phase component has been proposed (Patent Document 1). In addition to the aforementioned advantages, providing cosmetics by separating the powder-type solid-phase component from the formulation of the component used to dissolve it has the advantage of allowing users to experience a new sensation when using them by directly mixing the solid powders.
[0003] However, in cosmetics that are provided in separate formulations of powder-type solid phase ingredients and ingredients for dissolving them, in liquid phase formulations with low fluidity such as creams, the solid phase ingredients have difficulty penetrating into the formulation or are poorly redissolved due to limitations in hydration within the formulation, which limits the diversification of cosmetic formulations containing the above-mentioned solid phase ingredients.
[0004] Therefore, in order to provide a variety of cosmetic dosage forms, further research is needed to develop solid phase compositions with improved solubility in various dosage forms. Summary of the Invention [Problem to be solved by the invention]
[0005] As described above, in order to solve the problem of poor redissolution of water-dispersible polymer components in emulsion-type cosmetics with low fluidity, an object of the present invention is to provide a cosmetic composition, cosmetic product, or cosmetic kit containing a freeze-dried component of a composition containing a basic amino acid and a water-dispersible polymer. [Means for solving the problem]
[0006] In order to achieve the above-mentioned object, the present invention provides a solid phase cosmetic composition comprising a freeze-dried component of a composition comprising a water-dispersible polymer and a basic amino acid.
[0007] The freeze-dried ingredient containing both the water-dispersible polymer and the basic amino acid of the present invention contains the basic amino acid. When the freeze-dried ingredient is mixed with a dosage form for dissolving the freeze-dried ingredient, the polymer contained in the dosage form for dissolving the solid ingredient reacts with the amino acid of the freeze-dried ingredient to separate water molecules, thereby facilitating the re-dissolution of the functional ingredient contained in the freeze-dried ingredient in the dosage form.
[0008] In the present invention, the term "solid phase" refers to a solid state. A liquid composition may be solidified through processes such as drying, crystallization, or granulation, or may be reprocessed through processes such as pulverization to have a predetermined size range.
[0009] In the present invention, the freeze-dried component is an example of the solid phase and includes both freeze-dried substances and freeze-dried substances re-pulverized into powder.
[0010] The freeze-dried composition of the present invention can be prepared by dissolving a functional ingredient and a basic amino acid in a solvent to prepare an aqueous solution, cooling the aqueous solution to solidify the solution, and then reducing the pressure on the solidified solid sample at a low temperature below the triple point. When the pressure is reduced on a solid sample at a temperature below the triple point, water sublimes into a gas phase without passing through a liquid phase. At this time, the functional ingredient and basic amino acid maintain their structure dissolved in water, forming a porous structure. In this case, the porous structure can maintain its porosity without being destroyed during the grinding process, which is a macroscopic property change as a microstructure.
[0011] The basic amino acid of the present invention includes all basic amino acids and their derivatives. It contains a functional group that can bond with a hydrophilic functional group contained in a component such as a polymer contained in a high-hardness liquid dosage form, and reacts with the polymer to generate water molecules, thereby improving the resolubility of the functional ingredient in the high-hardness liquid dosage form. For example, an amine group (NH3 + The functional group contained in the basic amino acid can weaken the hydrogen bond between the hydrophilic functional group of the polymer in the liquid-phase dosage form and the hydroxyl group (—OH) of water when the basic amino acid is mixed with the emulsion dosage form, thereby dissolving out water molecules and allowing the water molecules to easily bind with the solid-phase components, thereby improving the hydration of the solid-phase components in the dosage form and thereby improving the solubility or resolubility of the solid-phase components.
[0012] In addition, the basic amino acid has an amine group (NH + ) and has a structure containing a carboxyl group or two or more hydroxyl groups, and has a structure that can act as a proton donor and acceptor within one molecule, so it can act as a buffer solution. Therefore, when a solid-phase cosmetic containing the basic amino acid is mixed with a cosmetic with low fluidity, it prevents a large change in pH within the formulation despite an increase in the resolubility of the solid phase, thereby preventing a decrease in the fluidity of the formulation and maintaining its stability.
[0013] The basic amino acid may be, for example, one or more selected from the group consisting of arginine, lysine, aspargine, histidine, citrulline, ornithine, tromethamine, and cysteamine, but is not limited thereto.
[0014] In the solid phase cosmetic composition of the present invention, the basic amino acid is contained in an amount of 1 to 90% (w / w), specifically 5 to 35% (w / w), but is not limited thereto.
[0015] The functional component is a component contained in a cosmetic to achieve a specific purpose, and in the present invention, may be a component that has low resolubility in an emulsion-type cosmetic having low fluidity.
[0016] The number of types of functional components is not limited, and one or more polymer components may be included. The polymer is not limited in size, but may be preferably a polymer of 300 kDa or less, more preferably 50 kDa or less. In the solid phase cosmetic composition of the present invention, the functional component may be included in an amount of 0.01% to 90% (w / w), preferably 10 to 80% (w / w).
[0017] The functional ingredient may be, for example, one or more of a water-dispersible polymer and an exfoliating ingredient.
[0018] The water-dispersible polymer is a polymer that dissolves in water, and examples thereof may include, but are not limited to, one or more selected from the group consisting of collagen, hydrolyzed hyaluronic acid, hyaluronic acid, β-glucan, xanthan gum, carboxymethyl cellulose, biosaccharide, cellulose, cellulose gum, gum arabic, gelatin, agar, carrageenan, algin, chitosan, starch, galactomannan, glucomannan, guar gum, locust bean gum, alginate, and gellan.
[0019] The exfoliating ingredient may be an amino acid or a hydroxy acid. The hydroxy acid may be an alpha hydroxy acid, a beta hydroxy acid, or a polyhydroxy acid. Specific examples of the exfoliating ingredient include, but are not limited to, one or more selected from the group consisting of serine, cysteine, threonine, glycine, tyrosine, aspartic acid, glutamic acid, histidine, carnitine, glycolate, lactate, malate, citrate, salicylate, and gluconolactic acid.
[0020] Furthermore, the solid phase cosmetic composition of the present invention may further contain one or more low molecular weight (1 kDa or less) functional ingredients as functional components. The solid phase cosmetic composition of the present invention may contain 0.01 to 99% (w / w), specifically 30 to 80% (w / w), and more specifically 45 to 65% (w / w). There is no limit to the content of low molecular weight functional ingredients. While increasing the content improves resolubility, it does not provide the skin adhesion, moisturizing power, and elasticity that high molecular weight active ingredients provide. Therefore, the content must be determined based on the content of the polymer.
[0021] The pH range of the solid phase cosmetic composition of the present invention is not limited, but can be 4.0 to 9.0, preferably 6.0 to 8.0. A pH higher or lower than this range may impair the stability of the active ingredient or induce skin irritation.
[0022] The solid phase cosmetic composition of the present invention, which contains a functional ingredient and a basic amino acid, may further contain a hydrophilic amino acid and / or an acidic amino acid. When the hydrophilic or acidic amino acid is further contained, when the freeze-dried ingredient is mixed with an emulsion-type cosmetic, the basic amino acid can act as a buffer to prevent the pH of the mixed cosmetic from increasing excessively.
[0023] The hydrophilic amino acid includes derivatives of amino acids, and may be, for example, one or more selected from the group consisting of serine, threonine, tyrosine, cysteine, asparagine, and glutamine, but is not limited thereto.
[0024] The acidic amino acid is an amino acid containing COOH in a branched chain, including amino acid derivatives, and may be, for example, one or more selected from the group consisting of aspartic acid and glutamic acid, but is not limited thereto.
[0025] The present invention also provides a solid-phase first composition comprising a freeze-dried component of a composition comprising a water-dispersible polymer and a basic amino acid; and 2 The present invention provides a cosmetic composition comprising a second composition in the form of an emulsion having a hardness of at least 100%.
[0026] The cosmetic composition may be a two-component composition containing a first composition and a second composition.
[0027] The present invention also provides a cosmetic product comprising the first composition and the second composition.
[0028] The first composition is a solid phase and comprises freeze-dried components of a composition comprising a functional ingredient and an amino acid, and the second composition is for dissolving the solid phase first composition and has an emulsified dosage form.
[0029] In the cosmetic product of the present invention, the first composition and the second composition may be contained in separate forms. The second composition used to dissolve the first composition is in the form of an emulsion, and there are no limitations on the type. Preferably, the second composition of the present invention is in the form of an emulsion with high hardness and low fluidity, and may be in the form of a cream, gel, or lotion. Functional ingredients, such as polymers, contained in the first composition have a problem of significantly low resolubility when reconstituted after lyophilization in formulations such as creams that lack sufficient moisture. The technical feature of the cosmetic product of the present invention is that it solves the problem of low resolubility of functional ingredients by incorporating a basic amino acid into the solid first composition, which requires reconstitution, by lyophilization.
[0030] In the present invention, the fluidity of the emulsion formulation can be defined by hardness, and is 5 dyne / cm 2 or more, or 5 to 100 dyne / cm 2 , or 10 to 50 dyne / cm 2 , or 25 to 35 dyne / cm 2 The hardness may be 0.01 or less.
[0031] Furthermore, the second composition in the emulsion dosage form may be one that does not cause a decrease in hardness of 30% or less when mixed with the first composition, or one that shows a decrease in hardness of 15% or less. In this case, when the two dosage forms are mixed and used, the stability of the second composition in the emulsion dosage form over time is not affected, and differentiated efficacy and usability can be provided to consumers.
[0032] The pH of the cosmetic composition of the present invention is not limited to a specific range, but may be 4.0 to 9.0, preferably 6.0 to 8.0. A pH higher or lower than this range may impair the stability of the active ingredient or cause skin irritation.
[0033] The cosmetic product may be a two-component cosmetic product containing a first composition and a second composition.
[0034] The present invention also provides a solid-phase first composition comprising a freeze-dried component of the composition comprising the water-soluble acidic polymer and the basic amino acid; and 2 The present invention provides a kit for producing a cosmetic product, which includes a second composition in the form of an emulsion having a hardness of at least 100%.
[0035] The present invention also provides a solid-phase first composition comprising a freeze-dried component of the composition comprising the water-soluble acidic polymer and the basic amino acid; and 2 The present invention provides a cosmetic kit including a second composition in the form of an emulsion having a hardness of at least 100%.
[0036] In the kit of the present invention, the first composition and the second composition may be contained in separate forms, i.e., the cosmetic kit may be a two-component cosmetic kit containing the first composition and the second composition, respectively.
[0037] In order to avoid repetition, the above descriptions regarding the cosmetic composition and the cosmetic product can be applied mutatis mutandis to the kit for producing the cosmetic product.
[0038] The present invention also provides a method for preparing a first solid-phase composition containing a freeze-dried composition comprising a functional ingredient and a basic amino acid, the method comprising: dissolving a functional ingredient and a basic amino acid in a solvent to prepare an aqueous solution; and cooling the aqueous solution to −20° C. to −180° C. to freeze-dry the solution;
[0039] 5 dyne / cm 2 The present invention provides a method for producing a cosmetic product having two dosage forms, which comprises the step of producing a second composition in an emulsion dosage form having the above hardness.
[0040] The method for manufacturing the cosmetic product may be a method for manufacturing a cosmetic product having two dosage forms containing a freeze-dried solid component with improved resolubility. The freeze-dried component of the solid phase contained in the first composition of the present invention contains both a functional component and a basic amino acid, and therefore can have excellent solubility in the dissolved dosage form even when redissolved after freeze-drying.
[0041] The freeze-drying can be carried out by cooling an aqueous solution in which a functional ingredient and a basic amino acid are dissolved to solidify it into a solid phase, and reducing the pressure on the solidified solid phase sample at a low temperature below the triple point.
[0042] The freeze-drying can be carried out at −20 to −180° C., or at −100 to −170° C., or at −120 to −170° C. When the freeze-drying is carried out at a temperature within the range claimed in the present invention, the quality of the freeze-dried product can be further improved, which is advantageous for use as a cosmetic.
[0043] Furthermore, the freeze-drying may further include pulverizing the freeze-dried solid phase. When the pressure of the solidified solid phase sample is reduced at a temperature below the triple point, water sublimes into a gas phase without passing through a liquid phase, but the functional ingredient and basic amino acid maintain their dissolved structure and form a porous structure. The porous structure is not destroyed during the pulverization process, which is a macroscopic property change, as a microstructure, and its porosity is maintained.
[0044] The solvent may be a solvent commonly used in the production of cosmetics or cosmetic products, and a preferred example may be water including purified water.
[0045] The functional ingredient may be one or more selected from the group consisting of collagen, hyaluronic acid, hydrolyzed hyaluronic acid, β-glucan, xanthan gum, carboxymethylcellulose, biosaccharide, cellulose, cellulose gum, gum arabic, gelatin, agar, carrageenan, algin, chitosan, starch, galactomannan, glucomannan, guar gum, locust bean gum, alginate, and gellan.
[0046] The basic amino acid may be, for example, one or more selected from the group consisting of arginine, lysine, aspargine, citrulline, ornithine, tromethamine, and cysteamine.
[0047] To avoid repetition, the above descriptions regarding the cosmetic composition and the cosmetic product may be applied mutatis mutandis to the method for producing the cosmetic product. [Effects of the Invention]
[0048] The present invention relates to a solid phase cosmetic composition comprising a freeze-dried component of a composition containing a functional ingredient and a basic amino acid. The solid phase component of the present invention has excellent resolubility and does not significantly change the hardness or pH of the cosmetic even after resolubilization, making it possible to provide a cosmetic with excellent stability. [Brief explanation of the drawings]
[0049] [Figure 1] FIG. 1 is a diagram illustrating the mechanism by which the solid phase composition of the present invention is dissolved in a liquid phase dosage form. [Figure 2] FIG. 2 is a graph showing the change in the dosage form over time when a solid phase composition according to an embodiment of the present invention is mixed with a liquid phase dosage form. DETAILED DESCRIPTION OF THE INVENTION
[0050] The following examples are intended to aid in the understanding of the present invention and should not be construed as limiting the scope of the present invention. [Example]
[0051] <Experimental Example 1. Preparation of solid dosage forms and cream dosage forms>
[0052] According to the composition of Table 1, a solid phase cosmetic composition containing arginine as an amino acid and hydrolyzed hyaluronic acid (0.5-10 kDa, SK Bioland, Korea) or hyaluronic acid (10 kDa or more, SK Bioland, Korea) as a functional polymer was prepared.
[0053] [Table 1]
[0054] Specifically, the components listed in Table 1 were dissolved in an excess amount of purified water to prepare an aqueous solution. The resulting solution was rapidly frozen at -150°C to solidify into a solid phase, followed by freeze-drying. The freeze-dried solid was then pulverized for ease of use to prepare a powdered solid composition of the present invention. When the pressure of a solid sample is reduced at a temperature below the triple point, the water sublimes without passing through a liquid phase and changes into a gas phase. At this time, the remaining components listed in Table 1 maintain their structure dissolved in water, forming a porous structure. The porous structure, as a microstructure, is not destroyed during the pulverization process, which is a macroscopic property change, and its porosity is maintained.
[0055] A second cosmetic composition for dissolving the solid phase cosmetic composition was prepared according to the composition in Table 2.
[0056] [Table 2]
[0057] A cream-type cosmetic with low fluidity was prepared using the composition shown in Table 2 as a preparation for dissolving a solid phase. The pH of the preparation was 7.15, and the hardness was measured at 30 dyne / cm using a hardness tester immediately after preparation. 2 It was confirmed that the hardness was measured using the most commonly used indentation hardness test method. The indentation hardness test is a test method in which a presser foot is pressed against a cosmetic material with a certain test load for a certain period of time, and the degree of indentation is then displayed as a numerical value. The hardness test was performed using a FUDOH RHEOMETER (Rheo Tech Co., Ltd., Japan).
[0058] <Test Example 1. Confirmation of changes in physical properties of the composition>
[0059] The solid cosmetic compositions prepared in Examples 1 and 2 and Comparative Example 1 were subjected to a 30 dyne / cm 2 When the solid phase components of Examples 1, 2, and Comparative Example 1 were mixed with the cream formulation, the degree of resolubility, resolubility time, and changes in pH and hardness of the composition were confirmed. Each solid phase component of Examples 1, 2, and Comparative Example 1 was taken with a spatula or by hand, and the cream formulation was mixed by hand to confirm resolubility (Figure 2).
[0060] [Table 3]
[0061] (◎: Very good, no clumping of powder particles, very uniform surface after reconstitution. ○: Good, almost no clumping of powder particles, uniform surface after reconstitution. △: Somewhat poor, slightly uneven surface after reconstitution, clumping occurred. X: Very poor, poor reconstitution, severe clumping.)
[0062] As shown in Table 3, in the solid phase compositions of Examples 1 and 2, which contain ultra-low molecular weight hydrolyzed hyaluronic acid and a basic amino acid, the solid phase components were rapidly redissolved into a low-fluidity cream according to the mechanism shown in Figure 1. However, the solid phase component of Comparative Example 1, which is composed only of functional polymers without a basic amino acid, required more than twice the redissolution time (measured as the time required to reach a uniformly mixed state that is invisible to the eye and feels unnatural to the touch) compared to Examples 1 and 2. In the case of a composition containing high molecular weight hyaluronic acid, as in Comparative Example 2, the solid phase components clumped so much that redissolution was not possible. While the use of a basic amino acid, as in Examples 3 and 4, demonstrated improved redissolution as proposed by the present invention, hydrolyzed hyaluronic acid is preferred for achieving superior cosmetic quality.
[0063] <Experimental Example 2. Preparation of a solid phase composition containing various polymeric functional components>
[0064] In order to confirm the degree of improvement in the resolubility of the composition of the present invention for various polymeric functional ingredients other than the hydrolyzed hyaluronic acid of Examples 1 and 2, solid phase cosmetic compositions were prepared according to the formulations in Table 4.
[0065] [Table 4]
[0066] <Test Example 2: Confirmation of resolubility of solid phase compositions containing various polymeric functional ingredients>
[0067] In order to confirm the resolubility of the solid phase compositions of Examples 5 to 7 and Comparative Examples 3 to 5 prepared in Experimental Example 2, the solid phase compositions were tested using the 30 dyne / cm 2 When the solid phase preparation was mixed with the cream preparation, the re-dissolution rate, the improvement rate (%) of the re-dissolution rate, and the changes in pH and hardness of the composition were confirmed.
[0068] Specifically, the improvement in the redissolution rate was confirmed by comparing the redissolution rate (1 / redissolution time) of the same polymer but without a basic amino acid (Comparative Examples 3 or 5) with that of the experimental groups containing a basic amino acid (Examples 5 to 7). Furthermore, the initial hardness (30 dyne / cm) of the cream formulation before mixing with the solid phase composition was also confirmed. 2 The rate of change in hardness was confirmed through the hardness of the solid phase composition and the cream formulation immediately after mixing.
[0069] [Table 5]
[0070] (◎: Very good, no clumping of powder particles, very uniform surface after reconstitution. ○: Good, almost no clumping of powder particles, uniform surface after reconstitution. △: Somewhat poor, slightly uneven surface after reconstitution, clumping occurred. X: Very poor, poor reconstitution, severe clumping.)
[0071] [Table 6]
[0072] <Test Example 3. Confirmation of resolubility in various formulations>
[0073] In order to confirm whether the solid phase composition of the present invention improves the resolubility in various formulations, the solid phase composition of Example 1 was dissolved in a cream formulation (30 dyne / cm) in Table 2. 2 In addition to the above, when mixed with essence (8100 cps) and solubilized toner (3800 cps), it was confirmed whether resolubility was improved compared to when mixed with the solid phase composition not containing amino acids in Comparative Example 1. The essence was prepared and evaluated according to the composition in Table 7, and the toner according to the composition in Table 8. The viscosity of the essence was measured using a Brookfield viscometer (Brookfield LV, Brookfield Engineering Laboratories, Inc., MA, USA) at 30 rpm for 60 seconds. The viscosity was measured after degassing during preparation to reduce the influence of air bubbles.
[0074] [Table 7]
[0075] [Table 8]
[0076] [Table 9]
[0077] (◎: Very good, no clumping of powder particles, very uniform surface after reconstitution. ○: Good, almost no clumping of powder particles, uniform surface after reconstitution. △: Somewhat poor, slightly uneven surface after reconstitution, clumping occurred. X: Very poor, poor reconstitution, severe clumping.)
[0078] As shown in Table 9, in the case of a solid composition obtained by freeze-drying a functional polymer and a basic amino acid together, the redissolution rate was improved in all formulations, including cream, essence, and toner, compared to the formulations obtained by mixing Comparative Example 1 with each formulation. In particular, it was confirmed that the improvement in the redissolution rate was greater in the cream formulation than in the solubilized toner, which has low viscosity / hardness and does not pose a significant problem of redissolution of the freeze-dried polymer.
[0079] <Test Example 4. Confirmation of the effect of amino acid type on improving resolubility>
[0080] In order to confirm whether neutral or acidic amino acids other than the basic amino acids of the present invention can also improve the resolubility of freeze-dried polymers, glutamic acid as an acidic amino acid, serine as a neutral amino acid, and arginine as a basic amino acid were freeze-dried together with functional polymers according to the composition shown in Table 10, and then the resolubility and hardness changes in the cream formulations shown in Table 2 were confirmed.
[0081] [Table 10]
[0082] [Table 11]
[0083] (◎: Very good, no clumping of powder particles, very uniform surface after reconstitution. ○: Good, almost no clumping of powder particles, uniform surface after reconstitution. △: Somewhat poor, slightly uneven surface after reconstitution, clumping occurred. X: Very poor, poor reconstitution, severe clumping.)
[0084] As shown in Table 10, neutral amino acids did not show any improvement in resolubility, while acidic and basic amino acids were found to have the effect of improving resolubility and time. However, it was confirmed that the hardness of the dosage form was reduced by the acidic amino acids, which increased the resolubility of the carbomer component. This effect was significantly less than the effect of using basic amino acids, which increased resolubility by weakening the binding force between the solid phase polymer and water.
