Problems to be solved by the invention

The present application provides a skin external agent composition, a cosmetic material composition or a mascara composition. It is a primary object of the present invention to provide a skin external composition, a cosmetic material composition or a mascara composition, which comprises a functional polymer suitable for film formation, exhibiting low solubility to polar and non-polar solvents, capable of preventing diffusion to the above solvents.

Technical scheme for solving problems

The composition for external skin preparations of the present application may contain a polymer described later. The above-mentioned external skin preparation composition can be formulated, for example, into a cosmetic composition such as a mascara composition. In this case, the above-mentioned composition may be formulated with a cosmetically or dermatologically acceptable medium or base.

The dosage form of the skin external agent composition, the cosmetic material composition or the mascara composition of the present application is not particularly limited, and various dosage forms may be formed according to purposes. For example, the above-mentioned dosage form may be suitably selected from powders, gels, ointments, creams, solutions, and the like. For example, the skin external composition can be prepared into a softening lotion, a nourishing cream, a massage cream, an essence, a foam, a mask, a lotion, a foundation cream, a gel, a lotion, a soap, a liquid cleanser, a body wash, a sunscreen cream, a sunscreen oil, a spray-type solution, an ointment, a paste, or a spray.

In one example, the composition for external application to skin can be applied to a hair-growing part where sebum and sweat are produced simultaneously, for example, a skin part where water resistance and oil resistance are required at the same time, such as eyebrow, hair, and underarm, and an example thereof is a mascara composition, but the composition is not limited thereto.

For example, the above mascara composition may contain a polymer described later as a film forming agent. In this case, the polymer can prevent the mascara composition from spreading due to tears, sweat, and the like, and can also prevent makeup from spreading due to sebum, and the like.

Next, the polymer contained in the skin external composition, cosmetic composition or mascara composition will be described.

The polymers of the present application exhibit low solubility to polar and non-polar solvents. In the present application, the term non-polar solvent means a solvent having a dielectric constant (dielectric constant) in the range of about 1 to 3, about 1.5 to 2.5, or about 1.5 to 2 at 25 ℃, and the term polar solvent means a solvent having a dielectric constant (dielectric constant) in the range of about 75 to 85 or about 75 to 80 at 25 ℃. As a representative example of the nonpolar solvent, hexane (dielectric constant (25 ℃ C.): about 1.89) can be given, and as a representative example of the polar solvent, water (dielectric constant (25 ℃ C.): about 78.54) can be given, but the present invention is not limited thereto. In the chemical field, the dielectric constant is known for each solvent.

In one example, the solubility of the polymer in the polar solvent may be 10 or less or 5 or less. In one example, the solubility of the polymer in the nonpolar solvent may be 10 or less or 5 or less. The solubility is not particularly limited, since the lower the value, the more excellent the resistance of the polymer to the solvent. In the present application, the solubility in a specific solvent means the number of grams (g) of a polymer that can be dissolved in 100g of the solvent to the maximum. In addition, unless otherwise specified, the solubility in the present application indicates a solubility measured at normal temperature. In the present application, the term normal temperature is a temperature in a natural state that is not warmed or reduced, and may be, for example, a temperature in a range of about 10 ℃ to 30 ℃, about 15 ℃ to 30 ℃, or about 20 ℃ to 30 ℃, or a temperature around about 25 ℃.

The polymer may exhibit suitable solubility to a solvent at an intermediate stage of the polar and nonpolar solvents. For example, the solubility of the above-mentioned polymer to a solvent having a dielectric constant (dielectric constant) at 25 ℃ in the range of 4 to 15, 5 to 10, or 5 to 8 may be 15 or more or about 15 to 50. Examples of such a solvent include: ethyl acetate (dielectric constant (25 ℃ C.): about 6.02), etc., but is not limited thereto.

The polymer having such characteristics as described above can be produced by, for example, adjusting the kind and ratio of monomers forming the polymer.

For example, the polymer may comprise a homopolymer having a solubility parameter of less than 10 (cal/cm)³)^1/2Has a solubility parameter of 10 (cal/cm) for the first monomer polymerized unit and the homopolymer of (a)³)^1/2The above second monomer polymerized unit.

In the present application, solubility parameter denotes the homopolymer obtained by polymerizing the corresponding monomerSolubility parameter of (homo polymer), from which the degree of hydrophilicity and hydrophobicity of the monomer can be confirmed. The method for determining the solubility parameter is not particularly limited, and may be a method known in the art. For example, the above-mentioned parameters can be calculated or obtained by a method known in the art as HSP (Hansen solubility parameter). Of the above, in another embodiment, the homopolymer of the first monomer may have a solubility parameter of 5 (cal/cm)³)^1/2To 9.5 (cal/cm)³)^1/2Or 7 (cal/cm)³)^1/2To 9 (cal/cm)³)^1/2In the left and right ranges. In addition, as described above, in another embodiment, the homopolymer of the second monomer may have a solubility parameter of 10 (cal/cm)³)^1/2To 15 (cal/cm)³)^1/2Or 10 (cal/cm)³)^1/2To 13 (cal/cm)³)^1/2In the left and right ranges. Monomers having solubility parameters in the above ranges can be suitably used to form polymers exhibiting the above-described characteristics.

In the present application, a polymerized unit of any monomer or compound means a form in which the monomer or compound is contained in a polymer as a monomer unit through a polymerization reaction.

As the first monomer, a plurality of monomers can be selected and used as long as they have the above solubility parameter. As the monomer that can be used as the first monomer, there can be exemplified: alkyl (meth) acrylates or aromatic (meth) acrylates. In the present application, the term (meth) acrylate may denote an acrylate or a methacrylate.

Examples of the alkyl group contained in the alkyl (meth) acrylate include: a linear, branched or cyclic alkyl group having 1 to 20 carbon atoms, 4 to 20 carbon atoms, 8 to 20 carbon atoms or 10 to 20 carbon atoms, which may be substituted with any one or more substituents. Examples of such monomers include: methyl (meth) acrylate, ethyl (meth) acrylate, n-propyl (meth) acrylate, isopropyl (meth) acrylate, n-butyl (meth) acrylate, t-butyl (meth) acrylate, sec-butyl (meth) acrylate, pentyl (meth) acrylate, 2-ethylhexyl (meth) acrylate, 2-ethylbutyl (meth) acrylate, n-octyl (meth) acrylate, isobornyl (meth) acrylate, isooctyl (meth) acrylate, isononyl (meth) acrylate, dodecyl (meth) acrylate, and the like, but are not limited thereto.

Examples of the aromatic (meth) acrylate include: aryl (meth) acrylates or arylalkyl (meth) acrylates. In the above, the aryl group of the aryl group or arylalkyl group may be, for example, an aryl group having 6 to 24 carbon atoms, 6 to 18 carbon atoms, or 6 to 12 carbon atoms. In addition, the alkyl group of the above arylalkyl group may be, for example, an alkyl group having 1 to 20 carbon atoms, 1 to 16 carbon atoms, 1 to 12 carbon atoms, 1 to 8 carbon atoms, or 1 to 4 carbon atoms. In the above, the alkyl group may be linear, branched or cyclic, and the above alkyl group or aryl group may be substituted with any one or more substituents.

Examples of the aryl group or arylalkyl group include: phenyl, phenethyl, phenylpropyl, naphthyl, or the like, but is not limited thereto.

As the first monomer, for example, a compound represented by the following chemical formula 1 can be illustrated.

[ chemical formula 1]

In chemical formula 1, Q may be hydrogen or an alkyl group, and B may be a linear or branched alkyl group or an alicyclic hydrocarbon group having 4 or more carbon atoms or an aromatic substituent such as the above-mentioned aryl group or arylalkyl group.

In chemical formula 1, as the alkyl group present in Q, an alkyl group having 1 to 20 carbon atoms, 1 to 16 carbon atoms, 1 to 12 carbon atoms, 1 to 8 carbon atoms, or 1 to 4 carbon atoms may be exemplified. The above alkyl group may be linear, branched or cyclic. The above alkyl group may be substituted with any one or more substituents.

In chemical formula 1, B may be a linear or branched alkyl group having 4 or more carbon atoms, 7 or more carbon atoms, or 9 or more carbon atoms. As such, compounds containing relatively long chain alkyl groups are referred to as hydrophobic compounds. The upper limit of the number of carbon atoms of the above-mentioned linear or branched alkyl group is not particularly limited, and for example, the above-mentioned alkyl group may be an alkyl group having 20 or less carbon atoms.

In other embodiments, B in chemical formula 1 may be an alicyclic hydrocarbon group, for example, an alicyclic hydrocarbon group having 3 to 20 carbon atoms, 3 to 16 carbon atoms, or 6 to 12 carbon atoms, and as examples of such a hydrocarbon group, there may be illustrated: alicyclic alkyl groups of 3 to 20 carbon atoms, 3 to 16 carbon atoms, or 6 to 12 carbon atoms such as cyclohexyl or isobornyl, and the like. Thus, a compound having an alicyclic hydrocarbon group is also referred to as a relatively hydrophobic compound.

In the present application, examples of the substituent which may be optionally substituted on an alkyl group, an alkylene group, an aromatic substituent or the like in the above chemical formula 1 or the below chemical formula 2 or 3 include a halogen group such as chlorine or fluorine; an epoxy group such as a glycidyl group, an alkylene oxide group, a glycidoxyalkyl group or an alicyclic epoxy group; acryl, methacryl, isocyanate, mercapto, alkyl, alkenyl, alkynyl, or aryl, and the like, but is not limited thereto.

An appropriate kind of monomer can be selected from the above-mentioned monomers in consideration of the physical properties of the target polymer.

As the second monomer, a monomer selected from monomers known to have the aforementioned solubility parameter may also be used.

For example, as the second monomer, a compound represented by the following chemical formula 2 or 3 may be used.

[ chemical formula 2]

In chemical formula 2, Q is hydrogen or alkyl, U is alkylene, Z is hydrogen or alkyl, and m is an arbitrary number;

[ chemical formula 3]

In chemical formula 3, Q is hydrogen or alkyl, a and U are each independently alkylene, and X is hydroxy or cyano.

In chemical formulas 2 and 3, as the alkylene group, an alkylene group having 1 to 20 carbon atoms, 1 to 16 carbon atoms, 1 to 12 carbon atoms, 1 to 8 carbon atoms, or 1 to 4 carbon atoms may be exemplified. The alkylene group may be linear, branched or cyclic. The alkylene group may be optionally substituted with one or more substituents.

In chemical formulas 2 and 3, as the alkyl group present in Q and Z, an alkyl group having 1 to 20 carbon atoms, 1 to 16 carbon atoms, 1 to 12 carbon atoms, 1 to 8 carbon atoms, or 1 to 4 carbon atoms may be exemplified. The above alkyl group may be linear, branched or cyclic. The alkyl group may be optionally substituted with one or more substituents.

In chemical formulas 2 and 3, m and n are any number, and for example, may each independently be a number in the range of 1 to 100, 1 to 90, 1 to 80, 1 to 70, 1 to 60, 1 to 50, 1 to 40, 1 to 30, 1 to 20, 1 to 16, or 1 to 12.

In one example, as the second monomer, a compound in which Q is hydrogen or an alkyl group having 1 to 4 carbon atoms, U is an alkylene group having 1 to 4 carbon atoms, Z is hydrogen or an alkyl group having 1 to 4 carbon atoms, and m is about 1 to 30 in the above chemical formula 2 may be used, but is not limited thereto.

The polymer can be prepared by polymerizing the above-mentioned first monomer and second monomer in an appropriate ratio.

For example, the polymer may include 50 to 99.9 parts by weight of the first monomer polymerization unit and 0.1 to 20 parts by weight of the second monomer polymerization unit. In another example above, the first monomer polymerized unit can be present from 60 to 99.9 parts by weight, from 70 to 99.9 parts by weight, or from 80 to 99.9 parts by weight. In addition, the second monomer polymerization unit may be included in 5 to 20 parts by weight or 7 to 20 parts by weight. In the present application, unless otherwise specified, the unit weight part may represent a ratio of the weight of each component. In the above, the weight ratio of the polymerized units of the monomers may be the weight ratio of the monomers used in the preparation of the polymer. Thus, for example, the polymer comprising 50 to 99.9 parts by weight of the first monomer-polymerized unit and 0.1 to 20 parts by weight of the second monomer-polymerized unit may represent a case where a monomer mixture comprising the first monomer and the second monomer in a weight ratio (first monomer: second monomer) of 50 to 99.9:0.1 to 20 is polymerized to form the polymer. In the polymer, when the weight ratio of the second monomer is less than 0.1 parts by weight or the weight ratio of the first monomer is more than 99.9 parts by weight, the resistance to an oily solvent or the sebum resistance may be insufficient, and when the weight ratio of the second monomer is more than 20 parts by weight or the weight ratio of the first monomer is less than 50 parts by weight, the polymer may not be formed due to phase separation or the like, or the resistance to a polar solvent or the resistance to sweat, tear fluid or the like may be insufficient. In the above, the weight part of each monomer may be a ratio of 100 parts by weight of the polymer.

The polymer may contain an additional monomer in addition to the first monomer and the second monomer, and may be used to impart other functions, for example, adjustment of the glass transition temperature.

The polymer can be produced by known polymerization methods using the first monomer and the second monomer. In one example, the polymer can be prepared by a solution polymerization method using a solvent (e.g., an organic solvent), for example, a radical solution polymerization method. For example, in the case where the polymer is used for applications such as cosmetics that contact the human body, a solvent that is friendly to the human body can be selected and used as the solvent in the polymerization process. As such a solvent, isododecane (isodecocane), isoparaffin, isohexadecane, or the like can be exemplified, but not limited thereto.

In the present application, the above-mentioned polymer may have a weight average molecular weight (Mw) in the range of 10000 to 500000. In the present application, the weight average molecular weight may be, for example, a value converted from standard polystyrene measured by GPC (Gel Permeation Chromatograph), and the term molecular weight may refer to the weight average molecular weight unless otherwise specified. The molecular weight (Mw) as described above is useful, for example, when the polymer is used as a film-forming agent. In the above molecular weight (Mw) range, the polymer can be used to efficiently form a film without aggregation or the like.

In the present application, the polymer may have a glass transition temperature in the range of 10 ℃ to 70 ℃. In the present application, the glass transition temperature is a theoretical value determined from the monomer composition of a polymer by the so-called Fox equation. The glass transition temperature as described above is useful, for example, when the polymer is used as a film-forming agent. In the range of the glass transition temperature, the polymer can be used to efficiently form a coating film without causing stickiness, chipping, or the like.

The polymer as described above can be used as a film forming agent (film former), for example. Such a polymer can be formed into a uniform film (coating film) by coating or the like, and exhibits high stability even when applied to the skin or the like, and exhibits resistance to both polar and nonpolar solvents, thereby being capable of exhibiting excellent resistance to various solvents such as sweat, tear fluid, or sebum.

Thus, the polymer can be suitably used for the preparation of a film-forming agent or a cosmetic composition which can be used for the preparation of various cosmetics including a cosmetic mask, a cosmetic such as mascara suitable for the corners of the mouth or eyes, a nail polish suitable for the fingernails or toenails, a lipstick, an eye shadow, a hair setting agent, an eyeliner, and the like. The polymer, the film-forming agent, and the like can also be used for medical purposes due to the above-mentioned properties, and examples of the medical purposes include a thin plaster sheet, a transdermal preparation, and the like.

The ratio of the polymer in the skin external composition, the cosmetic composition or the mascara composition is not particularly limited, and may be selected in consideration of the application and the like. For example, the polymer may be included in the above-mentioned skin external agent composition, cosmetic material composition or mascara composition at a ratio ranging from about 1% to 20% by weight.

The above-mentioned skin external agent composition, cosmetic material composition or mascara composition may contain an oil as an additional ingredient. The oil component, for example, functions to maintain the dispersibility of the polymer in the composition within a suitable range, thereby improving the long-term storage stability of the composition and allowing the composition to exhibit a soft feeling in use.

As the oil, a known wax can be used without particular limitation, but as an oil which can exhibit an excellent effect by being used together with the above-mentioned polymer, an oil having an α value in the range of 0 to 60 or 10 to 45 can be exemplified. In the above, the α value represents a criterion for comparing the polarity value of an organic compound by doctor takayata (a. fujita) (Prediction of organic compounds by a conceptual diagram (1954)), and the details are described in the above documents.

The oil is not particularly limited as long as it has the above-described properties and can be applied to an external preparation for skin. Examples of such oils include: glyceryl triisooctanoate, cetearyl octanoate, isononyl isononanoate, octyl palmitate, hexyl laurate, ethyl octadecanoate, octyldodecanol pivalate, octyldodecanol stearate, isostearyl isostearate, isopropyl myristate, isopropyl palmitate, butyl stearate, diisostearyl malate, neopentyl glycol diheptanoate, polyglyceryl-2-diisostearate, triisostearyl citrate, tridecanol trimellitate, polyglyceryl-2-triisostearate, pentaerythritol mercaptopropionate, pentaerythritol tetraisostearate, pentaerythritol tetraisononanoate, glyceryl tri (2-decyl) tetradecanoate, polyglyceryl-2-tetraisostearate, pentaerythritol tetra (2-decyl) tetradecanoate, octyl palmitate, hexyl laurate, ethyl octadecanoate, octyl dodecanol pivalate, octyl dodecanol stearate, stearyl stearate, isostearyl alcohol, isopropyl myristate, octyl palmitate, octyl stearate, isobutyl stearate, octyl myristate, octyl palmitate, octyl myristate, octyl palmitate, and octyl palmitate, octyl myristate, octyl palmitate, and octyl palmitate, each, Caprylic/capric triglyceride, triheptanoin, tricaprylin (Glyceryl trioctanoate), isohexadecane, isoparaffin, liquid paraffin, polybutene, polyisobutene, hydrogenated polyisobutene, polydecene, hydrogenated polydecene, castor oil, olive oil, sandalwood oil, or baccarat oil, but is not limited thereto.

The ratio of the oil in the composition is not particularly limited, and may be adjusted in consideration of the purpose, for example, dispersibility of the polymer, and the like. In one example, the oil can be present in the composition at a ratio of about 0.1 to 10 wt%, or about 2 to 7 wt%, but is not limited thereto.

The above-mentioned skin external agent composition, cosmetic material composition or mascara composition may contain wax as an additional ingredient. The wax component may, for example, serve to provide a fluffy feel when the composition is used.

As the wax, a known wax can be used without particular limitation, but it is preferable to use a wax having crystallinity at normal temperature so that resistance to sebum or the like can be secured by using the wax together with the polymer.

As the wax, for example, a wax having a melting point in the range of about 30 ℃ to 120 ℃ can be used, and such a wax can be effectively used together with the aforementioned polymer.

The penetration index of the above waxes may also be in the range of 3 to 40. The penetration index can be measured in the manner specified in KS M2252: 2007 (test method for penetration of asphalt materials).

As the wax, any known wax may be used without particular limitation as long as it has the above-described properties and can be applied to a skin preparation for external use. Examples of such waxes include rice bran wax, carnauba wax, candelilla wax, ouricury (ouricurry) wax, alfalfa wax, cork fiber wax (corrk fiber wax), sugar cane wax, japan wax, water film wax, montan wax, microcrystalline waxes, paraffins, and ozokerite; polyethylene waxes, waxes obtained by a Fischer-Tropsch (Fischer-Tropsch) synthesis method (hereinafter, also referred to as Fischer-Tropsch waxes), waxy copolymers or esters thereof, waxes obtained by catalytic hydrogenation of animal or vegetable oils having a linear or branched aliphatic chain, for example, a linear or branched aliphatic chain having 8 to 32 carbon atoms, hydrogenated jojoba oil, hydrogenated sunflower oil, hydrogenated castor oil, hydrogenated coconut oil, hydrogenated lanolin oil, or silicone waxes, but are not limited thereto.

The ratio of the wax in the composition is not particularly limited, and may be adjusted in consideration of various uses, for example, in the case of a mascara formulation, a curl effect which can make eyelash appear plump, a proper voluminous feeling, and lift eyelash, and the like. In one example, the wax may be included in the composition at a ratio of 1 to 30% by weight in the composition, but is not limited thereto.

Detailed Description

The present invention will be specifically explained below by way of examples and comparative examples, but the scope of the present invention is not limited to the following examples.

In the following examples and comparative examples, physical properties were evaluated in the following manner.

1. Measurement of Polymer solubility

The polymer solutions prepared in examples or comparative examples were maintained at a temperature of about 150 c for about 60 minutes to volatilize the solvent. 1g of the polymer was extracted to volatilize the solvent. The extracted 1g of polymer was put into 5g of a solvent (hexane, ethyl acetate, acetone or water), stirred at room temperature for 30 minutes, and then insoluble residual polymer was removed. The transparent solution from which the residual polymer was removed was fractionated, and dried at 150 ℃ for 30 minutes to remove the solvent. The solid content was calculated by comparing the mass of the polymer remaining in the solvent-removed solution. The concentration of the polymer dissolved in the solvent was measured by the solid content, and the solubility was determined by converting the measured amount into a numerical value for 100g of the solvent. In the case where the solution is also opaque after the residual polymer is removed, the above-mentioned process is carried out after passing the solution through a filter (0.45 μm, NYLON) to obtain a transparent solution.
