Abstract
Description
[Technical field]
[0001] The present invention relates to a composition comprising a polyion complex, a film of the polyion complex, a method for preparing a film by using the polyion complex, and a cosmetic method using the polyion complex. [Background technology]
[0002] Hyaluronic acid is the main glycosaminoglycan found in the skin. Therefore, fibroblasts mainly synthesize collagen, non-collagenous matrix glycoproteins (fibronectin, laminin), proteoglycans and elastin. Keratinocytes, for their part, mainly synthesize sulfated glycosaminoglycans and hyaluronic acid. Hyaluronic acid is also called hyaluronan (HA).
[0003] Hyaluronic acid is present in free form in the epidermis and dermis and is responsible for the turgor of the skin. This polysaccharide can actually hold large volumes of water, up to 1000 times its mass. In this sense, hyaluronic acid plays an important role in increasing the amount of water bound in tissues, and also in the mechanical properties of the skin and in wrinkle formation.
[0004] Hyaluronic acid has been widely used as a cosmetic ingredient due to its high moisturizing effect.
[0005] However, aqueous solutions of hyaluronic acid are sticky, which can result in an unpleasant texture, and the hyaluronic acid film that forms when an aqueous solution of hyaluronic acid dries on the skin is also sticky, which can also result in an unpleasant texture.
[0006] WO2021 / 125069 discloses reducing stickiness caused by hyaluronic acid by forming polyion complex particles having a cationic polymer and hyaluronic acid as an anionic polymer. [Prior art documents] [Patent documents]

[0030] Compositions and films according to the present invention can be transparent or translucent.
[0031] Compositions and coatings according to the present invention can provide long-lasting antioxidant benefits.
[0032] Thus, the present invention may be useful, for example, to protect the skin from damage caused by peroxidation of unsaturated lipids such as sebum, which may be alterations in desquamation, squalene loss, acne and blackheads, dullness of the skin, and ageing, such as the formation of wrinkles and / or fine lines.
[0033] Furthermore, compositions and films according to the present invention may be based on hyaluronic acid or cationized hyaluronic acid to provide long-lasting cosmetic benefits and / or improved moisturizing texture.
[0034] Furthermore, the stickiness of the composition according to the present invention can be reduced as compared to a composition containing hyaluronic acid that does not form a polyion complex.
[0035] A film containing a polyion complex, which film may contain at least one surfactant, can be easily prepared by applying the composition onto a substrate, preferably a keratinous material such as skin and hair, more preferably onto skin, and allowing the composition to dry.
[0036] The stickiness of the film according to the present invention can be reduced as compared to a film of hyaluronic acid that does not form a polyion complex.
[0037] The coating according to the invention may be porous. The surface of the coating according to the invention may be uneven or rough.
[0038] The coating according to the invention can have various cosmetic functions, for example, the coating can provide a moisturizing effect based on hyaluronic acid or cationized hyaluronic acid in a polyion complex.
[0039] A film according to the present invention can trap sebum, impart a matte appearance to keratinous materials such as skin, absorb or adsorb malodors, and / or protect keratinous materials from, for example, dirt or pollutants.
[0040] When the film contains at least one cosmetic active ingredient such as oil, the film can also have the cosmetic effect provided by the cosmetic active ingredient. For example, when the polyion complex film contains at least one cosmetic active ingredient selected from UV shielding agent, (b) anti-aging agent other than hydrophilic antioxidant, sebum suppressing agent, deodorant agent, antiperspirant, whitening agent, and mixtures thereof, the film can shield UV rays, treat skin aging, absorb sebum on the skin, control odor on the skin, control sweat on the skin, and / or whiten the skin.
[0041] Coatings according to the present invention can be transparent or translucent and therefore may be difficult to perceive, even when the coating is relatively thick.
[0042] Furthermore, the film according to the invention is water resistant and therefore can remain on keratinous materials such as skin even when the surface of the keratinous material is wet, for example due to sweat or rain.
[0043] Furthermore, the film according to the present invention can be easily removed from keratinous materials such as skin under alkaline conditions. Thus, the film according to the present invention is difficult to remove with water, but can be easily removed with soap that can provide alkaline conditions.
[0044] Therefore, when the film according to the present invention contains a hydrophilic or water-soluble UV blocking agent, the film according to the present invention can be resistant to water (waterproof) and exhibit a long-lasting UV blocking effect, but can be easily removed with a soap that can provide alkaline conditions.

[0125] Unless otherwise defined in the description, "molecular weight" may mean number average molecular weight.
[0126] According to the invention, the anionic polymer is chosen from hyaluronic acid, its salts and its derivatives.
[0127] Hyaluronic acid has the chemical formula:
[0128] [ka]
[0129] It can be expressed as:
[0130] In the context of the present invention, the term "hyaluronic acid" refers specifically to a compound of the formula:
[0131] [ka]
[0132] This is the smallest fraction of hyaluronic acid that contains the disaccharide dimer, D-glucuronic acid and N-acetylglucosamine.
[0133] The term "derivative" of hyaluronic acid, in the context of the present invention, includes linear polymers comprising the above-listed polymer units linked together in a chain via alternating β(1,4) and β(1,3) glycosidic bonds, with a molecular weight (MW) that can range between 380 and 13,000,000 daltons, which depends mainly on the source from which the hyaluronic acid is obtained and / or on the method of preparation.
[0134] The term "salt" of hyaluronic acid, in the context of the present invention, includes any salt of hyaluronic acid, including alkali metal salts such as sodium salts and potassium salts, alkaline earth metal salts such as magnesium salts, ammonium salts, and mixtures thereof.
[0135] In nature, hyaluronic acid is present in the percellular gel in the matrix of connective tissues of vertebrate organs, such as the dermis and epithelial tissues, specifically in the epidermis, in the synovial fluid of joints, in the vitreous humor, in the human umbilical cord and in the crest process.
[0136] The term "hyaluronic acid" therefore includes all fractions or subunits of hyaluronic acid having molecular weights especially within the molecular weight ranges recalled above.
[0137] In the context of the present invention, hyaluronic acid fractions that do not have inflammatory activity are preferably used.
[0138] Reference may be made to the publication "Hyaluronan fragments: an information-rich system", R. Stern et al., European Journal of Cell Biology 58 (2006) pp. 699-715, which reviews the enumerated biological activities of hyaluronic acid according to its molecular weight through examples of various hyaluronic acid fractions.
[0139] According to a preferred embodiment of the present invention, the hyaluronic acid fraction suitable for use in the present invention has a molecular weight between 50 kDa and 5,000 kDa, in particular between 100 kDa and 5,000 kDa, and more particularly between 400 kDa and 5,000 kDa, in which case the term used is high molecular weight hyaluronic acid.
[0140] Alternatively, hyaluronic acid fractions that may also be suitable for use within the present invention have a molecular weight between 50 kDa and 400 kDa, in which case the term used is intermediate molecular weight hyaluronic acid.
[0141] Again, alternatively, hyaluronic acid fractions that may be suitable for use within the present invention have a molecular weight of less than 50 kDa, in which case the term used is low molecular weight hyaluronic acid.
[0142] It may be preferable to use a combination of two or more types of hyaluronic acid or its salt, for example, a combination of a high molecular weight hyaluronic acid or its salt with a medium molecular weight hyaluronic acid or its salt, a combination of a high molecular weight hyaluronic acid or its salt with a low molecular weight hyaluronic acid or its salt, and a combination of a medium molecular weight hyaluronic acid or its salt with a low molecular weight hyaluronic acid or its salt.
[0143] Finally, the term "derivatives" of hyaluronic acid also includes hyaluronic acid esters, in particular those in which all or part of the carboxylic acid groups of the acid functions are esterified with oxyethylated alkyls or alcohols containing 1 to 20 carbon atoms, in particular those in which the degree of substitution of the D-glucuronic acid level of hyaluronic acid ranges from 0.5 to 50%.
[0144] Mention may in particular be made of the methyl, ethyl, n-propyl, n-pentyl, benzyl and dodecyl esters of hyaluronic acid. Such esters are described in detail in D. Campoccia et al., "Semisynthetic resorbable materials from hyaluronan esterification", Biomaterials 19 (1998) pp. 2101-2127.
[0145] The hyaluronic acid derivative may be, for example, acetylated hyaluronic acid or a salt thereof.
[0146] The molecular weights given above are also valid for hyaluronic acid esters.
[0147] Specifically, hyaluronic acid is sold by Hyactive under the trade name CPN (MW: 10-150 kDa) and by Soliance under the trade name Cristalhyal (MW: 1.1×10 6 ), supplied by Bioland under the name Nutra HA (MW: 820,000 Da), supplied by Bioland under the name Nutra AF (MW: 69,000 Da), supplied by Bioland under the name Oligo HA (MW: 6100 Da), or supplied by Vam Farmacos Metica under the name D Factor (MW: 380 Da).
[0148] The amount of anionic polymer in the composition according to the invention may be greater than or equal to 0.01% by weight, preferably greater than or equal to 0.03% by weight, more preferably greater than or equal to 0.05% by weight, relative to the total weight of the composition.
[0149] The amount of anionic polymer in the composition according to the invention may be up to 15% by weight, preferably up to 10% by weight, more preferably up to 5% by weight, relative to the total weight of the composition.
[0150] The amount of anionic polymer in the composition according to the present invention may be from 0.01% to 15% by mass, preferably from 0.03% to 10% by mass, more preferably from 0.05% to 5% by mass, based on the total mass of the composition.
[0151] (Amphoteric polymer) Amphoteric polymers have both positive and negative charge densities.
[0152] The positive charge density of the amphoteric polymer may be from 0.01 to 20 meq / g, preferably from 0.05 to 15 meq / g, and more preferably from 0.1 to 10 meq / g.
[0153] The negative charge density of the amphoteric polymer may be from 0.01 to 20 meq / g, preferably from 0.05 to 15 meq / g, and more preferably from 0.1 to 10 meq / g.
[0154] It may be preferred that the molecular weight of the amphoteric polymer is 500 or more, preferably 1,000 or more, more preferably 10,000 or more, and even more preferably 100,000 or more.
[0155] It may be preferred that the molecular weight of the amphoteric polymer is 1,000,000 or less, preferably 900,000 or less, more preferably 800,000 or less.
[0156] Unless otherwise defined in the description, "molecular weight" may mean number average molecular weight.
[0157] According to the invention, the amphoteric polymer is selected from cationized hyaluronic acid and its salts.
[0158] Cationized hyaluronic acid contains at least one cationic group, such as an ammonium group, in its molecule, which does not exhibit a counter cation of the salt, since there is no counter cation in the hyaluronic acid molecule.
[0159] Salts may include alkali metal salts such as sodium salts, alkaline earth metal salts such as magnesium salts, ammonium salts, and mixtures thereof.
[0160] The cationized hyaluronic acid may have at least one quaternary ammonium group-containing group.
[0161] The cationized hyaluronic acid and / or a salt thereof may be represented by the following general formula (1):
[0162] [ka]
[0163] [In the formula, R 4 ~R 9 are each independently a hydrogen atom or a quaternary ammonium group-containing group (R 4 ~R 9 represents a hydrogen atom), and n represents an integer of 2 to 5,000. The compound may have a structure shown by:
[0164] In the above general formula (1), R 4 ~R 9 Examples of quaternary ammonium group-containing groups represented by the following general formula (2):
[0165] [ka]
[0166] (In the formula, R 1 ~R 3 each represents a hydrocarbon group; X - represents a monovalent anion) Examples of the groups include those represented by the following formula:
[0167] In the above general formula (2), R 1 ~R 3 Examples of the hydrocarbon group represented by include linear or branched alkyl groups, unsaturated hydrocarbon groups, and aromatic hydrocarbon groups. Among these, alkyl groups are preferred. Examples of the alkyl groups include alkyl groups having 1 to 30 (preferably 1 to 6) carbon atoms. R 1 ~R 3 It is more preferable that the hydrocarbon group represented by the following formula: is an alkyl group having 1 to 3 carbon atoms.
[0168] In the above general formula (2), X - Examples of monovalent anions represented by include halogen ions such as fluoride, bromide, chloride, and iodide.
[0169] The quaternary ammonium group-containing group can be introduced by replacing the hydrogen atom of the carboxyl group contained in the hyaluronic acid and / or its salt used as the raw material (hereinafter referred to as "raw material hyaluronic acid and / or its salt") with the quaternary ammonium group-containing group. In this case, the quaternary ammonium group-containing group is bonded to the oxygen atom of the (-C(-O)O-) group contained in the cationized hyaluronic acid and / or its salt according to this embodiment. The fact that the quaternary ammonium group-containing group is bonded to the oxygen atom of the (-C(-O)O-) group contained in the cationized hyaluronic acid and / or its salt according to this embodiment can be seen by nuclear magnetic resonance ( 13 The presence of a peak attributable to the carbon atom of the -C(-O)O- group to which the quaternary ammonium group-containing group is bonded via an oxygen atom can be confirmed by analyzing the chemical shifts in the C NMR spectrum.
[0170] Specifically, the quaternary ammonium group-containing group can be obtained by reacting the carboxyl group (and / or hydroxyl group) of raw material hyaluronic acid and / or its salt with a cationizing agent containing a quaternary ammonium group.Preferably, the cationizing agent is at least one of 2.3-epoxypropyltrialkylammonium halide as shown in the following general formula (3) and 3-halogeno-2-hydroxypropyltrialkylammonium halide as shown in the following general formula (4).The reaction of raw material hyaluronic acid and / or its salt with a cationizing agent is described in the preparation method hereinafter.
[0171] [ka]
[0172] [In the formula, R 1 ~R 3 is the same as defined for general formula (2), and X represents a halogen atom.
[0173] [ka]
[0174] [In the formula, R 1 ~R 3 is the same as defined for general formula (2), and X and Y each represent a halogen atom.
[0175] Examples of the halogen atoms represented by X and Y in the above general formulas (3) and (4) include a fluorine atom, a bromine atom, a chlorine atom and an iodine atom.
[0176] The cationized hyaluronic acid may have at least one quaternary ammonium group-containing group, and has a degree of cationization of 0.05 to 0.6, preferably 0.1 to 0.5, and more preferably 0.15 to 0.4.
[0177] The degree of cationization of the cationized hyaluronic acid and / or its salt according to the present embodiment (i.e., the degree of substitution with a quaternary ammonium group-containing group) can be determined by calculating the nitrogen content of the raw material sodium hyaluronate and the nitrogen content of the cationized hyaluronic acid by the semi-micro Kjeldahl method, and calculating the degree of cationization according to the following formula based on the increase in nitrogen content:
[0178] The nitrogen content of the raw material sodium hyaluronate is N N The nitrogen content of the cationized hyaluronic acid having a degree of cationization of (x) is referred to as N S When referring to the increase in nitrogen content (N S -N N The relationship between the degree of cationization (x) and the amount of cationization (x) is given by the following formula: N S -N N (%) = [14x / (molecular weight of disaccharide unit of cationized hyaluronic acid)] × 100 = [14x / (molecular weight of disaccharide unit of raw material sodium hyaluronate) + 129.5x] x 100 =[14x / (401.3+129.5x)]×100 As shown by:
[0179] Therefore, the degree of cationization (i.e., the degree of substitution with a quaternary ammonium group-containing group) can be calculated by the following formula: Degree of cationization (x) = [(N S -N N )×401.3] / [1400-129.5 * (N S -N N )]
[0180] When the raw material hyaluronic acid is unknown, the degree of cationization of the cationized hyaluronic acid can be calculated by the above formula on the assumption that the raw material sodium hyaluronate is sodium hyaluronate having a purity of 99% or more.
[0181] It is possible for 1% or more, preferably 5% or more, more preferably 10% or more, and / or 50% or less, preferably 40% or less, more preferably 30% or less of the anionic groups in hyaluronic acid to be replaced with cationic groups, preferably with quaternary ammonium group-containing groups, more preferably with quaternary ammonium group-containing groups represented by the above general formula (2).
[0182] Cationic hyaluronic acids include hydroxypropyltrimonium hyaluronate, commercially available as Hyaloveil and Hyaloveul-MPF by Kewpie Corporation, Japan.
[0183] The amount of amphoteric polymer in the composition according to the invention may be greater than or equal to 0.01% by weight, preferably greater than or equal to 0.03% by weight, more preferably greater than or equal to 0.05% by weight, relative to the total weight of the composition.
[0184] The amount of amphoteric polymer in the composition according to the invention may be up to 15% by weight, preferably up to 10% by weight, more preferably up to 5% by weight, relative to the total weight of the composition.
[0185] The amount of amphoteric polymer in the composition according to the present invention may be from 0.01% to 15% by mass, preferably from 0.03% to 10% by mass, more preferably from 0.05% to 5% by mass, based on the total mass of the composition.
[0186] (Non-polymeric acids with two or more acid dissociation constants) The composition according to the present invention may comprise at least one non-polymeric acid or salt thereof having two or more pKa values, i.e., at least one non-polymeric acid or salt thereof having two or more acid dissociation constants. pKa values (acid dissociation constants) are well known to those skilled in the art and should be determined at a constant temperature, such as 25°C.
[0187] A non-polymeric acid or salt thereof having two or more pKa values can be included in the (a) polyion complex. A non-polymeric acid having two or more pKa values can function as a crosslinker, specifically an anionic crosslinker for cationic polymers and / or amphoteric polymers.
[0188] It is preferred that a non-polymeric acid or salt thereof having two or more pKa values be used in conjunction with the cationic and anionic polymers.
[0189] The term "non-polymeric" as used herein means that the acid is not obtained by polymerizing two or more monomers, and thus does not correspond to acids obtained by polymerizing two or more monomers, such as polycarboxylic acids.
[0190] It is preferred that the molecular weight of the non-polymeric acid or salt thereof having two or more pKa values is 1000 or less, preferably 800 or less, and more preferably 700 or less.
[0191] There is no limitation on the type of non-polymeric acid or its salt having two or more pKa values.

[0352] Since the method for preparing a film according to the present invention includes a step of applying the composition according to the present invention to a substrate, preferably a keratinous material, more preferably the skin, and a step of drying the composition, the method according to the present invention does not require any spin coating or spraying, and therefore even a relatively thick film can be easily prepared. Therefore, the method for preparing a film according to the present invention can prepare a relatively thick film without using any special equipment such as a spin coater or a spray machine.
[0353] The presently claimed coatings may be transparent or translucent and may provide long-lasting antioxidant benefits.
[0354] Even when the film according to the invention is relatively thick, it can still be thin and transparent and therefore difficult to perceive, so that the film according to the invention can preferably be used as a cosmetic film.
[0355] The presently claimed coating may be less sticky even though it contains a hyaluronic acid based polymer.
[0356] If the substrate is not a keratinous material such as skin, the composition according to the present invention can be applied onto a substrate made of any material other than keratin. The material of the non-keratinous substrate is not limited. Two or more materials may be used in combination. Thus, a single type of material or a combination of different types of materials can be used. In any case, it is preferred that the substrate is flexible or elastic.
[0357] If the substrate is not a keratinous material, it is preferred that the substrate is water-soluble, since it is possible to leave the film according to the invention by washing the substrate with water. Examples of water-soluble materials include poly(meth)acrylic acid, polyethylene glycol, polyacrylamide, polyvinyl alcohol (PVA), starch, cellulose acetate, etc. PVA is preferred.
[0358] When the non-keratin substrate is in the form of a sheet, the substrate may have a thickness greater than that of the coating according to the present invention in order to facilitate handling of the coating attached to the substrate sheet. The thickness of the non-keratin substrate sheet is not limited, but may be 1 μm to 5 mm, preferably 10 μm to 1 mm, more preferably 50 to 500 μm.
[0359] It is more preferred that the film according to the present invention is removable from the non-keratin substrate. The manner of removal is not limited. Thus, the film according to the present invention may be peeled off from the non-keratin substrate, or may be removed by dissolving the substrate sheet in a solvent such as water.
[0360] The present invention also provides (1) A film, preferably a decorative film, optionally having a thickness of preferably more than 0.1 μm, more preferably 0.5 μm or more, even more preferably 1 μm or more, applying a composition according to the invention onto a substrate, preferably a keratinous material, more preferably the skin; drying the composition; a film, preferably a cosmetic film, prepared by a process comprising: and (2) A film, preferably a decorative film, optionally having a thickness of preferably more than 0.1 μm, more preferably 0.5 μm or more, even more preferably 1 μm or more, (a) at least one cationic polymer and at least one anionic polymer; at least one cationic polymer and at least one amphoteric polymer; at least one anionic polymer and at least one amphoteric polymer, or at least one amphoteric polymer, At least one non-polymeric acid or salt thereof having two or more pKa values; or At least one non-polymeric base or salt thereof having two or more pKb values At least one polyion complex comprising (b) at least one hydrophilic antioxidant; Optionally, (d) at least one surfactant, preferably selected from nonionic surfactants, more preferably selected from polyglyceryl fatty acid esters; Including, The anionic polymer is selected from hyaluronic acid and its salts; and A film, preferably a cosmetic film, in which the amphoteric polymer is selected from cationized hyaluronic acid and its salts. Also relates to.
[0361] The above comments regarding the cationic, anionic and amphoteric polymers, and the hydrophilic antioxidants and surfactants described above, can be applied to coatings (1) and (2) above.
[0362] The film thus obtained above can be self-supporting. The term "self-supporting" as used herein means that the film can be in the form of a sheet and can be handled as an independent sheet without the aid of a substrate or support. Therefore, the term "self-supporting" can have the same meaning as "self-supporting".
[0363] It is preferred that the coating according to the present invention is hydrophobic.
[0364] The term "hydrophobic" as used herein means that the solubility of the polymer in water (preferably in a volume of 1 liter) at 20-40° C., preferably 25-40° C., more preferably 30-40° C., is less than 10% by weight, preferably less than 5% by weight, more preferably less than 1% by weight, even more preferably less than 0.1% by weight, based on the total weight of the polymer. Most preferably, the polymer is not soluble in water.
[0365] When the film according to the present invention is hydrophobic, the film can have water-resistant properties, and therefore the film can remain on the keratinous material, such as the skin, even when the surface of the keratinous material is wet, for example, by sweat or rain, so that when the film according to the present invention provides any cosmetic benefit, the cosmetic benefit can last for a long time.
[0366] On the other hand, the film according to the invention can be easily removed from keratinous materials such as skin under alkaline conditions, such as a pH of 8 to 12, preferably 9 to 11. Thus, the film according to the invention is difficult to remove with water, whereas the film can be easily removed with soaps capable of providing such alkaline conditions.
[0367] The coating according to the present invention may comprise at least one biocompatible and / or biodegradable polymer layer. Two or more biocompatible and / or biodegradable polymers may be used in combination. Thus, a single type of biocompatible and / or biodegradable polymer or a combination of different types of biocompatible and / or biodegradable polymers may be used.
[0368] As used herein, the term "biocompatible" polymer means that the polymer does not have excessive interactions between the polymer and cells in the body, including the skin, and the polymer is not recognized as foreign by the body.
[0369] The term "biodegradable" polymer as used herein means that the polymer can be broken down or broken down in vivo, for example by the metabolism of the organism itself or by the metabolism of microorganisms that may be present in the organism. Biodegradable polymers can also be broken down by hydrolysis.
[0370] When the coating according to the present invention comprises a biocompatible and / or biodegradable polymer, it causes little or no irritation to the skin and does not cause any rashes. In addition, the use of a biocompatible and / or biodegradable polymer allows the decorative sheet according to the present invention to adhere well to the skin.
[0371] The film according to the present invention can be used for the cosmetic treatment of keratinous materials, preferably skin, especially face.The film according to the present invention can be in any shape or form.For example, the film can be used as a full face mask sheet, or a patch for a part of the face, such as cheeks, nose, and around the eyes.
[0372] When the film according to the present invention comprises at least one hydrophilic or water-soluble UV blocking agent, the film can provide UV blocking effect derived from the hydrophilic or water-soluble UV blocking agent.Normally, the hydrophilic or water-soluble UV blocking agent can be removed from the surface of keratin substrate such as skin by water such as sweat and rain.However, since the hydrophilic or water-soluble UV blocking agent is contained in the film according to the present invention, the hydrophilic or water-soluble UV blocking agent is difficult to be removed by water, thereby providing long-lasting UV blocking effect.
[0373] [Cosmetic methods and uses] The present invention also provides A cosmetic method for keratinous materials such as the skin, comprising the steps of applying a composition according to the present invention to the keratinous materials and drying the composition to form a cosmetic film on the keratinous materials, and Use of the composition according to the invention for preparing a cosmetic film on a keratinous material such as the skin Also relates to.
[0374] Cosmetic method means herein a non-therapeutic cosmetic method for caring for and / or making up the surfaces of keratinous materials such as the skin.
[0375] In both the above method and use, the above decorative film is resistant to water having a pH of 7 or less and is removable with water having a pH of greater than 7, preferably 8 or more, more preferably 9 or more.
[0376] In other words, the decorative coating can be water-resistant under neutral or acidic conditions, such as a pH of 7 or less, preferably in the range of ≧6 to ≦7, more preferably in the range of ≧5 to ≦7, while the decorative coating can be removed under alkaline conditions, such as a pH of more than 7, preferably more than 8, more preferably more than 9. The upper limit of pH is preferably 13, more preferably 12, even more preferably 11.
[0377] Accordingly, the cosmetic film can be water-resistant, and therefore can remain on the keratinous material, such as the skin, even when the surface of the keratinous material is wet, for example due to sweat or rain. On the other hand, the cosmetic film can be easily removed from the keratinous material, such as the skin, under alkaline conditions. Thus, the film according to the present invention is difficult to remove with water, but can be easily removed with a soap that can provide alkaline conditions.
[0378] When said cosmetic film comprises a UV filter, which may be present in the composition according to the invention, said cosmetic film can protect keratinous materials such as skin from UV rays, thereby reducing skin darkening, improving skin tone and evenness, and / or treating skin aging.
[0379] Furthermore, the above-mentioned cosmetic films may have cosmetic benefits such as trapping sebum, imparting a matte appearance to keratinous substrates such as skin, absorbing or adsorbing malodors, and / or protecting keratinous materials from, for example, dirt or pollutants, due to the properties of the polyion complexes in the cosmetic films, even when the cosmetic films do not contain any cosmetic active ingredients.
[0380] In addition, the cosmetic film can instantly change or modify the appearance of the skin, such as by changing the light reflection on the skin, even if the cosmetic film does not contain any cosmetic active ingredients. Thus, the cosmetic film can be capable of hiding skin imperfections, such as pores or wrinkles. Furthermore, the cosmetic film can instantly change or modify the feel of the skin, such as by changing the surface roughness on the skin. Furthermore, the cosmetic film can instantly protect the skin from environmental stresses, such as pollutants, impurities, etc., by covering the surface of the skin and shielding the skin as a barrier.
[0381] The cosmetic benefits can be adjusted or controlled by varying the chemical composition, thickness and / or surface roughness of the cosmetic film.
[0382] When the cosmetic film includes at least one additional cosmetic active ingredient such as oil, the cosmetic film can have a cosmetic effect brought about by the additional cosmetic active ingredient. For example, when the cosmetic film includes at least one cosmetic active ingredient selected from (b) an anti-aging agent other than a hydrophilic antioxidant, a sebum suppressant, a deodorant agent, an antiperspirant, a whitening agent, and a mixture thereof, the cosmetic film can treat skin aging, absorb sebum on the skin, control odor on the skin, control sweat on the skin, and / or whiten the skin.
[0383] After the cosmetic film or cosmetic sheet according to the present invention has been applied to the skin, it is also possible to apply a make-up cosmetic composition thereon. EXAMPLES
