Description

[Technical Field]

[0001] The present invention relates to a composition comprising a polyion complex and a wax, and to a cosmetic method using the composition. [Background technology]

[0002] As is well known in the art, certain cosmetic compositions use a polyion complex formed of anionic polymers and cationic polymers.

[0003] For example, WO2021 / 125069 discloses a composition useful for cosmetic treatments, comprising at least one polyionic complex particle containing at least one cationic polymer, at least one anionic polymer, and at least one nonpolymeric acid having two or more pKa values. WO2021 / 125069 also discloses that the composition disclosed herein may contain oil and may be in the form of an emulsion.

[0004] On the other hand, for example, in order to prevent or reduce the transfer of cosmetic color from keratinous substances such as skin to items such as masks, there has been a need for compositions with good transfer resistance, particularly for makeup cosmetics. Even in the case of non-makeup cosmetics such as skincare cosmetics, the transfer of cosmetics from keratinous substances such as skin to items such as masks is undesirable because this transfer may reduce the effectiveness of the skincare cosmetics by causing them to be lost to the keratinous substances.

[0022] The composition according to the present invention may further contain (e) water.

[0023] The present invention also relates to a cosmetic method for keratinous substances such as skin, comprising the step of applying a composition according to the present invention to the keratinous substance. [Modes for carrying out the invention]

[0024] As a result of diligent research, the inventors have discovered that it is possible to provide a composition that can have good transfer prevention properties.

[0025] Therefore, the composition according to the present invention is (a) at least one cationic polymer, (b) at least one anionic polymer, (c) Nonpolymeric acids or salts thereof having at least one of two or more pKa values, (d) at least one type of wax Includes, (a) The cationic polymer is selected from polylysine, chitosan, and mixtures thereof. (b) The anionic polymer is selected from hyaluronic acid, its derivatives, its salts, and mixtures thereof. (d) The amount of wax is 1% by mass or more relative to the total mass of the composition.

[0026] (a) a cationic polymer, (b) an anionic polymer, and (c) a nonpolymeric acid or salt thereof having two or more pKa values ​​can form a polyionic complex. In particular, (a) a cationic polymer can be ionically crosslinked with (c) a nonpolymeric acid or salt thereof having two or more pKa values.

[0027] The polyion complex may be in the form of droplets. When the polyion complex is in the form of droplets, the droplet size may be 5 nm to 100 μm, preferably 100 nm to 50 μm, more preferably 200 nm to 40 μm, and even more preferably 500 nm to 30 μm. Droplet sizes less than 1 μm can be measured by dynamic light scattering, and droplet sizes greater than 1 μm can be measured by optical microscopy.

[0028] The composition according to the present invention can have good transfer prevention properties, that is, good transfer resistance.

[0029] Therefore, the compositions according to the present invention can leave deposits or films on keratinous substances such as skin, and these deposits or films remain on the keratinous substance and do not easily transfer from the keratinous substance to articles that come into contact with it. For example, a composition according to the present invention applied to skin such as facial skin does not easily move or transfer to articles such as masks or objects such as fingers that come into contact with the skin.

[0030] If the cosmetic composition according to the present invention is, for example, a makeup cosmetic composition, the composition can exhibit good color transfer resistance, and therefore the color of the composition is less likely to transfer to or transfer to an article that comes into contact with the composition. As a result, the cosmetic composition according to the present invention can provide a long-lasting makeup effect and / or reduce staining on an article.

[0031] If the cosmetic composition is, for example, a skincare cosmetic composition, the composition can also exhibit good transfer resistance, and therefore the composition is less likely to transfer to or transfer to an article that comes into contact with the composition. Therefore, the cosmetic composition according to the present invention can provide long-lasting skincare effects and / or reduce staining on articles.

[0032] Accordingly, the present invention can provide the user with long-lasting skincare and other beauty benefits, even when the user is using a mask on their face or when they unconsciously touch their face with their fingers.

[0033] Furthermore, the compositions according to the present invention, based on hyaluronic acid, its derivatives, or salts thereof, can provide cosmetic effects such as moisturizing and anti-wrinkle effects.

[0034] Furthermore, since polylysine, chitosan, hyaluronic acid, its derivatives, and salts can be obtained from natural, sustainable resources such as biomass, (a) cationic polymers and (b) anionic polymers can be environmentally friendly components. Therefore, compositions according to the present invention may contain environmentally friendly components.

[0035] The present invention will be described in more detail below.

[0036] [Composition] The composition according to the present invention is (a) at least one cationic polymer, (b) at least one anionic polymer, (c) Nonpolymeric acids or salts thereof having at least one of two or more pKa values, (d) at least one type of wax Includes, (a) The cationic polymer is selected from polylysine, chitosan, and mixtures thereof. (b) The anionic polymer is selected from hyaluronic acid, its derivatives, its salts, and mixtures thereof. (d) The amount of wax is 1% by mass or more relative to the total mass of the composition.

[0037] (cationic polymer) The composition according to the present invention comprises (a) at least one cationic polymer. Two or more different types of cationic polymers may be used in combination. Therefore, a single type of cationic polymer or a combination of different types of cationic polymers can be used.

[0038] (a) The cationic polymer has a positive charge density. (a) The charge density of the cationic polymer may be 0.01 meq / g to 20 meq / g, preferably 0.05 to 15 meq / g, and more preferably 0.1 to 10 meq / g.

[0039] (a) The molecular weight (Da) of the cationic polymer may be less than 20,000, preferably less than 15,000, and more preferably less than 10,000.

[0040] (a) The molecular weight (Da) of the cationic polymer may be greater than 1,000, preferably greater than 1,500, and more preferably greater than 2,000.

[0041] Therefore, (a) the molecular weight (Da) of the cationic polymer may be greater than 1,000 and less than 20,000, preferably greater than 1,500 and less than 15,000, and more preferably greater than 2,000 and less than 10,000.

[0042] Unless otherwise defined in the description, "molecular weight" refers to the mass-average molecular weight. Molecular weight can be measured or determined by gel permeation chromatography, for example, in accordance with ASTM D5296-19.

[0043] According to the present invention, (a) the cationic polymer is selected from the group consisting of polylysine, chitosan, and mixtures thereof.

[0044] Polylysine is well known.

[0045] Polylysine is a condensation of several amino acids of lysine. Polylysine can be a natural homopolymer of L-lysine that can be produced by bacterial fermentation. Polylysine is typically used as a natural preservative in food. Polylysine is a polyelectrolyte soluble in polar solvents such as water.

[0046] Polylysine may be, for example, epsilon-polylysine (or "ε-polylysine"), which is a condensation of the amino group and carboxyl group at the ε position of lysine, or alpha-polylysine (or "α-polylysine"), which is a condensation of the amino group and carboxyl group at the α position of lysine. Polylysine is commercially available in various forms such as poly-D-lysine and poly-L-lysine. Generally, polylysine is a condensate of L-lysine, i.e., poly-L-lysine. Polylysine is preferably polyepsilon-lysine (INCI name).

[0047] Examples of polylysine include the following: - A 25% solution of epsilon-poly-L-lysine having a molecular weight of approximately 4,700 in aqueous solution, and epsilon-poly-L-lysine from JNC CORPORATION, and - Polylysine (poly-ε-lysine) from Shandong Freda Biotechnology, in the form of a white to creamy yellow powder with a molecular weight between 4,130 and 5,776.

[0048] According to one particular embodiment, the polylysine may be a modified polylysine, for example, the polylysine having a fatty acid chain described in patent application FR2889448, the polylysine having a guanidine or biguanidine functional group described in patent application FR2851465, or the thiolated polylysine described in patent application FR2853533.

[0049] Polylysine may be in the form of an organic or inorganic salt. Acid addition salts include, for example, hydrochloride or hydrobromide, sulfate, citrate, succinate, tartrate, lactate, p-toluenesulfonate, phosphate, or acetate; or fatty acid salts such as linoleate, oleate, palmitate, stearate, behenate, and 18-methylicosanate. Base addition salts include, for example, sodium salt, calcium salt, or hydroxyalkylamine salt, such as N-methylglucamine, aminopropanediol, or triethanolamine.

[0050] In some preferred embodiments of the present invention, the polylysine of the present invention exists in the composition as a single molecule or is not covalently bonded to other compounds. In one embodiment of the present invention, the polylysine is not covalently bonded to a dye compound. In one embodiment of the present invention, the polylysine is not covalently bonded to a polyorganosiloxane compound. The term "polyorganosiloxane" is well known in the art and means a compound having a Si-O backbone and organic functional groups bonded to the backbone.

[0051] In another embodiment of the present invention, polylysine is in a free form. The term “free form” as used herein indicates that polylysine is not covalently bonded to any other compound.

[0052] Chitosan is also well known.

[0053] Chitosan is extremely rare in nature. It has only been reported in the exoskeleton of certain insects, such as termite queens, and in the cell walls of certain classes of fungi, specifically the class Zygomycetes.

[0054] Chitosan can be obtained by the deacetylation of chitin. Chitin is a polysaccharide composed of several N-acetyl-D-glucosamine units linked together by β-linkages (1,4).

[0055] The ideal chemical structure of chitosan is a sequence of β-D-glucosamine monomers linked by glycosidic bonds (1→4).

[0056] The "chitosan" according to the present invention refers to any copolymer formed from the constituent units N-acetyl-D-glucosamine and D-glucosamine, wherein the degree of acetylation is less than 90%, preferably less than 80%, preferably less than 70%, preferably less than 60%, and preferably less than 50%. Chitosan consists of glucosamine sugar units (deacetylated units) and N-acetyl-D-glucosamine units (acetylated units) linked together by β-type bonds (1,4), and is a poly(N-acetyl-D-glucosamine)-poly(D-glucosamine) type polymer.

[0057] More preferably, the degree of acetylation of chitosan is 40% or less, preferably 35% or less, preferably 25% or less, preferably 15% or less, and preferably 10% or less.

[0058] The degree of acetylation is the percentage of acetylated units relative to the total number of units, and can be determined by Fourier transform infrared spectroscopy (FT-IR) or titration with a strong base.

[0059] The chitosan of the present invention is preferably a polysaccharide prepared from fungal sources. In particular, it is extracted and purified from fungal sources of safe and abundant food or biotechnology, such as mushrooms (Agaricus bisporus) or black mold (Aspergillus niger).

[0060] The chitosan of the present invention is preferably derived from fungi of the class Ascomycete, particularly Aspergillus oryzae and / or Basidiomycete fungus, specifically the mycelium of Lentinula edodes and / or button mushrooms. Preferably, the fungus is Aspergillus oryzae.

[0061] Chitosan may be of genetically modified organism (GMO) origin, but is preferably of non-GMO origin.

[0062] The chitosan according to the present invention is natural, that is, unmodified. In particular, it contains no chemical modifications whatsoever.

[0063] One method for preparing chitosan is described in WO03 / 068824.

[0064] The amount of (a) cationic polymer in the composition according to the present invention may be 0.001% by mass or more, preferably 0.002% by mass or more, and more preferably 0.003% by mass or more, based on the total mass of the composition.

[0065] The amount of (a) cationic polymer in the composition according to the present invention may be 15% by mass or less, preferably 10% by mass or less, and more preferably 5% by mass or less, based on the total mass of the composition.

[0066] The amount of (a) cationic polymer in the composition according to the present invention may be 0.001% to 15% by mass, preferably 0.002% to 10% by mass, and more preferably 0.003% to 5% by mass, based on the total mass of the composition.

[0067] (Anionic polymer) The composition according to the present invention comprises (b) at least one anionic polymer. Two or more different types of anionic polymers may be used in combination. Therefore, a single type of anionic polymer or a combination of different types of anionic polymers can be used.

[0068] (b) The anionic polymer has a negative charge density. (b) If the anionic polymer is a synthetic anionic polymer, the charge density of the anionic polymer may be 0.1 meq / g to 20 meq / g, preferably 1 to 15 meq / g, more preferably 4 to 10 meq / g, and (b) if the anionic polymer is a natural anionic polymer, the average degree of substitution of the anionic polymer may be 0.1 to 3.0, preferably 0.2 to 2.7, more preferably 0.3 to 2.5.

[0069] According to the present invention, (b) the anionic polymer is selected from hyaluronic acid, its derivatives, its salts, and mixtures thereof.

[0070] In the context of this invention, the term "hyaluronic acid, its derivatives, its salts, and mixtures thereof" includes hyaluronic acid, hyaluronic acid salts, hyaluronic acid derivatives, hyaluronic acid derivative salts, and mixtures thereof.

[0071] Hyaluronic acid is the dominant glycosaminoglycan found in the skin. Therefore, fibroblasts predominantly synthesize collagen, non-collagenous matrix glycoproteins (fibronectin, laminin), proteoglycans, and elastin. Keratinogenic cells predominantly synthesize sulfated glycosaminoglycans and hyaluronic acid for these components. Hyaluronic acid is also known as hyaluronan.

[0072] Hyaluronic acid exists in a free state within the epidermis and dermis and influences the fullness of the skin. This polysaccharide can actually hold a large volume of water, equivalent to up to 1000 times its own mass. In this sense, hyaluronic acid plays an important role in increasing the amount of water bound within tissues, as well as in the mechanical properties of the skin and wrinkle formation.

[0073] Hyaluronic acid can be represented by the following chemical formula:

[0074] [ka]

[0075] In the context of this invention, the term "hyaluronic acid" specifically includes the basic unit of hyaluronic acid as shown in the following formula.

[0076] [ka]

[0077] The above represents the smallest fraction of hyaluronic acid containing disaccharide dimers, namely D-glucuronic acid and N-acetylglucosamine.

[0078] In the context of this invention, the term "hyaluronic acid" refers to a linear polymer comprising the above-mentioned polymer units linked together in the chain via alternating β(1,4) and β(1,3) glucosidic bonds, having a molecular weight (Mw) that can range between 380 and 13,000,000 daltons. This molecular weight depends primarily on the source from which the hyaluronic acid is obtained and / or the method of preparation.

[0079] In the context of this invention, the term "hyaluronic acid" also includes hydrolyzed hyaluronic acid.

[0080] In the context of this invention, the term "hyaluronic acid derivative" includes hyaluronic acid esters, particularly those containing 1 to 20 carbon atoms, in which the degree of substitution at the D-glucuronic acid level of hyaluronic acid is in the range of 0.5% to 50%, and in which all or part of the carboxylic acid groups of the acidic functional group are esterified with an oxyethylene alkyl or alcohol.

[0081] In particular, methyl, ethyl, n-propyl, n-pentyl, benzyl, and dodecyl esters of hyaluronic acid can be mentioned. Such esters are described in detail by D. Campoccia et al., "Semisynthetic resorbable materials from hyaluronan esterification," Biomaterials 19 (1998), pp. 2101-2127.

[0082] In one embodiment, the hyaluronic acid derivative may be, for example, acetylated hyaluronic acid.

Therefore, (b) the molecular weight of the anionic polymer may be 5 kDa to 20 MDa, preferably 20 kDa to 10 MDa, more preferably 100 kDa to 2,000 kDa.

[0088] Unless otherwise defined in the description, "molecular weight" may mean mass-average molecular weight. Molecular weight can be measured or determined by gel permeation chromatography, for example, in accordance with ASTM D5296-19.

[0258] The present invention will be described in more detail by reference to examples. However, these should not be construed as limiting the scope of the present invention.

[0259] (Example 1 and Comparative Example 1) [Preparation] The compositions from Example 1 and Comparative Example 1 were prepared by mixing the components shown in Table 1. All numerical values ​​for the amounts of components in Table 1 are based on "mass%" as active materials.

[0260] [Table 1]

[0261] [evaluation] (Prevents transfer to masks) 100 mg of the composition from Example 1 was applied to half of an artificial skin plate (Bioskin, manufactured by Beaulax). The blue dye was added to the composition from Example 1 so that the concentration of the blue dye in the composition from Example 1 was 0.01% by mass relative to the total mass of the composition.

[0262] As a control, 100 mg of the composition from Comparative Example 1 was applied to the remaining half of an artificial skin plate (Bioskin, manufactured by Beaulax). The blue dye was added to the composition from Comparative Example 1 so that the concentration of the blue dye in the composition from Comparative Example 1 was 0.01% by mass relative to the total mass of the composition.

[0263] The composition on the artificial skin plate was completely dried at room temperature.

[0264] A nonwoven mask was placed on the composition on the artificial skin. A glass plate was placed on the nonwoven mask and pressed down on it for 10 seconds. The glass plate was then removed from the nonwoven mask. The degree of transfer of each composition to the nonwoven mask was then visually inspected, and the differences in transfer were evaluated according to the following criteria.

[0265] A: Completely different (No transfer was observed in Example 1, but a clear and substantial transfer was observed in Comparative Example 1.) B: Clearly different (Transfer was observed in Example 1 and Comparative Example 1. However, the degree of transfer was clearly different; only slight transfer was observed in Example 1, while significantly more transfer was observed in Comparative Example 1.) C: Slightly different (Transfer was observed in Example 1 and Comparative Example 1. However, the degree of transfer differed; a clearly visible transfer was observed in Example 1, while substantially more transfer was observed in Comparative Example 1.) D: No difference (Similar degrees of shift were observed in Example 1 and Comparative Example 1.)

[0266] The above method was repeated three times. The average of the evaluation results is shown in Table 1.

[0267] (summary) As is clear from Table 1, the composition according to Example 1 showed good transfer prevention to the mask. In other words, there was no transfer from the artificial skin to the nonwoven mask with the composition according to Example 1, while there was clear and substantial transfer from the artificial skin to the nonwoven mask with the composition according to Comparative Example 1. This difference may be due to the presence of synthetic wax in the composition according to Example 1.
