Description

[Technical field]

[0001] The present invention relates to a spray-type makeup protection cosmetic composition. [Background technology]

[0002] Conventionally, highly durable makeup cosmetics have been known, but studies have been conducted to further enhance the durability of the cosmetic effect by applying a coating agent on top of the makeup cosmetic. For example, Patent Document 1 describes that a makeup coating agent containing a silicone-modified alkyl acrylate polymer is applied on top of a makeup agent to maintain the cosmetic effect of the makeup agent for a long time, and is not sticky or causes any uncomfortable feeling of tightness or stiffness on the skin. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2002-370935 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, conventional coating agents have issues such as noticeable color transfer of makeup cosmetics when wearing a nonwoven fabric mask, and discomfort such as a tight feeling and stickiness after application. [Means for solving the problem]

[0005] The inventors have discovered that spraying a spray-type makeup protection cosmetic composition containing a graft polymer with an organosiloxane main chain in combination with an appropriate amount of a nonionic surfactant after application of makeup cosmetics (containing powder) improves the adhesion between the skin and the powder in the makeup cosmetics, makes the cosmetics more resistant to external physical stress, and improves the durability of the makeup cosmetics.

Effect of the Invention

[0007] The spray-type makeup protection cosmetic composition of the present invention is sprayed after application of the makeup cosmetic composition, so that the makeup lasts for a long time, and even if a nonwoven mask is worn, the color does not transfer to the nonwoven mask after a long time. In addition, immediately after application (spraying), there is no feeling of tightness or stickiness on the forehead, and the skin is given a moist and shiny feel, and even after a long time, the skin does not feel dry.

[0015] In the general formula (1), t is the number 2 or 3, and is preferably 2 from the viewpoint of availability of raw materials when producing organopolysiloxane.

[0016] The mass ratio (a / b) is in the range of 45 / 55 to 99 / 1. As the organopolysiloxane (AA), from the viewpoints of enabling the makeup to last for a long time when sprayed after application of a makeup cosmetic, suppressing color transfer to a nonwoven fabric mask even after a long period of time has passed, and suppressing a feeling of tightness and stickiness on the forehead immediately after application (spraying) and imparting a moist and lustrous feeling to the skin, it is preferable to use a combination of an organopolysiloxane (A1) having an organopolysiloxane segment (a) constituting the main chain and a poly(N-acylalkyleneimine) segment (b) in a mass ratio (a / b) of 45 / 55 to 72 / 28 and an organopolysiloxane (A2) having an (a / b) ratio of 82 / 18 to 99 / 1. When organopolysiloxane (A1) and organopolysiloxane (A2) are used in combination, the mass ratio (A2) / (A1) of component (A2) to component (A1) is preferably 1 or more, more preferably 2 or more, even more preferably 3 or more, and is preferably 25 or less, more preferably 20 or less, and even more preferably 14 or less, from the viewpoints of ensuring that makeup lasts for a long time when sprayed after application of a makeup cosmetic and suppressing color transfer to a nonwoven fabric mask after a long period of time has passed, even if the nonwoven fabric mask is worn. The mass ratio (A2) / (A1) of component (A2) to component (A1) is preferably 1 to 25, more preferably 2 to 20, and even more preferably 3 to 14.

[0017] In this specification, the mass ratio (a / b) is determined by dissolving 5% by mass of organopolysiloxane (AA) in deuterated chloroform and measuring the mass ratio by nuclear magnetic resonance ( 1 This refers to the value determined from the integral ratio of alkyl or phenyl groups in the organopolysiloxane segment to methylene groups in the poly(N-acylalkyleneimine) segment by H-NMR analysis.

[0018] In the organopolysiloxane (AA), the weight average molecular weight (hereinafter also simply referred to as "MWg") of the organopolysiloxane segment between adjacent poly(N-acylalkyleneimine) segments is in the range of 1,000 to 40,000, and from the viewpoint of the flexibility of the cosmetic film, it is preferably 10,000 to 35,000, and more preferably 15,000 to 32,000.

[0019] In this specification, the term "organopolysiloxane segment between adjacent poly(N-acylalkyleneimine) segments" refers to a portion surrounded by a dashed line between the two points from the bonding point (bonding point A) of the poly(N-acylalkyleneimine) segment to the organopolysiloxane segment to the bonding point (bonding point B) of the adjacent poly(N-acylalkyleneimine) segment, as shown in the following formula (2), and is a region in which one R 2 SiO unit and one R 3 And y+1 (R 2 The term "poly(N-acylalkyleneimine) segment" refers to a segment composed of the above R 3 -ZR binds to 4 This refers to.

[0020] [ka]

[0021] In the above general formula (2), R 2 each independently represents an alkyl group having 1 to 22 carbon atoms or a phenyl group; R 3 represents an alkylene group containing a heteroatom, -ZR 4indicates a poly(N-acylalkyleneimine) segment, and R 4 represents a residue of a polymerization initiator, and y represents a positive number. 2 , R 3 , R 4 may be the same or different.

[0022] MWg is the molecular weight of the portion enclosed by the dashed line in the above general formula (2), and can be interpreted as the mass (g / mol) of the organopolysiloxane segment per mole of the poly(N-acylalkyleneimine) segment. When the functional groups of the modified organopolysiloxane, which is the raw material compound, are 100% substituted with poly(N-acylalkyleneimine), it coincides with the functional group equivalent (g / mol) of the modified organopolysiloxane.

[0023] The molecular weight of the poly(N-acylalkyleneimine) segment can be calculated from the molecular weight and degree of polymerization of the N-acylalkyleneimine unit, or can be measured by gel permeation chromatography (hereinafter, also simply referred to as "GPC") measurement. In the present invention, it refers to the polystyrene-equivalent number average molecular weight (hereinafter, also simply referred to as "MNox") measured by GPC measurement performed under the measurement conditions described below. MNox is preferably in the range of 500 to 7000, more preferably 800 to 6500, and even more preferably 1000 to 6000, from the viewpoint of producing a solid cosmetic preparation having excellent moldability and elasticity.

[0024] The MWg can be calculated from the content (mass %) of organopolysiloxane segments constituting the main chain (hereinafter, simply referred to as "Csi") according to the following formula (I). MWg=Csi×MNox / (100-Csi) (I)

[0025] The weight average molecular weight (hereinafter, simply referred to as "MWsi") of the organopolysiloxane segment constituting the main chain is 15,000 to 200,000, and preferably 25,000 to 170,000, more preferably 30,000 to 150,000, from the viewpoint of the flexibility of the cosmetic and the adhesion to the skin. In addition, the organopolysiloxane (AA) can be easily blended into various products by dissolving in a polar solvent such as water. Since the organopolysiloxane segment constituting the main chain has a common skeleton with the modified organopolysiloxane, which is a raw material compound, the MWsi is approximately the same as the weight average molecular weight of the modified organopolysiloxane, which is a raw material compound. The weight average molecular weight of the modified organopolysiloxane, which is a raw material compound, is measured by GPC under the measurement conditions described below and converted into polystyrene.

[0026] From the viewpoint of excellent adhesion to skin, the weight average molecular weight (hereinafter, also simply referred to as "MWt") of the organopolysiloxane (AA) is preferably 15,000 to 200,000, more preferably 30,000 to 170,000, and even more preferably 50,000 to 150,000. MWt is a value measured by gel permeation chromatography (GPC) under the measurement conditions described below, and converted into polystyrene equivalent.

[0027] In addition to having a high elastic modulus and a large amount of deformation, organopolysiloxane (AA) has the characteristic thermoplasticity that when heated to temperatures in the range of 50 to 220°C, its plasticity improves significantly and it becomes soft, but when heating is stopped and the temperature returns to room temperature, it quickly regains its elasticity.

[0028] The organopolysiloxane (AA) is, for example, a compound represented by the following general formula (3):

[0029] [ka]

[0030] (In the formula, R 2 has the same meaning as above, R 5 and R 6 are R 2or the following formulae (viii) to (xiii):

[0031] [ka]

[0032] R represents a monovalent group represented by any one of the following: 7 represents a monovalent group represented by the above formulas (viii) to (xiii), d represents a number from 91.5 to 1255.0, and e represents a number from 2.0 to 62.5. and a modified organopolysiloxane represented by the following general formula (4):

[0033] [ka]

[0034] (In the formula, R 1 and t have the same meaning as above) It is produced by reacting a cyclic imino ether represented by the following formula (1) with a terminally reactive poly(N-acylalkyleneimine) obtained by ring-opening polymerization of the cyclic imino ether represented by the following formula (1):

[0035] A polymerization initiator can be used for the ring-opening polymerization of the cyclic imino ether represented by general formula (4) (hereinafter, simply referred to as "cyclic imino ether (4)"). As the polymerization initiator, a compound having strong electrophilic reactivity, for example, an alkyl ester of a strong acid such as an alkyl ester of benzenesulfonate, an alkyl ester of p-toluenesulfonate, an alkyl ester of trifluoromethanesulfonate, an alkyl ester of trifluoroacetate, or a dialkyl sulfate can be used, and among them, a dialkyl sulfate is preferably used.

[0036] Examples of the polymerization solvent that can be used include acetates such as ethyl acetate and propyl acetate, ethers such as diethyl ether, diisopropyl ether, dioxane and tetrahydrofuran, ketones such as acetone and methyl ethyl ketone, halogenated solvents such as chloroform and methylene chloride, nitrile solvents such as acetonitrile and benzonitrile, and aprotic polar solvents such as N,N-dimethylformamide, N,N-dimethylacetamide and dimethylsulfoxide, among which acetates are preferably used. The amount of the solvent used is usually 20 to 2000 parts by mass relative to 100 parts by mass of the cyclic iminoether (4).

[0037] The polymerization temperature is usually 30 to 170° C., preferably 40 to 150° C., and the polymerization time varies depending on the polymerization temperature etc., but is usually 1 to 60 hours.

[0038] For example, when 2-substituted-2-oxazoline is used as the cyclic iminoether (4), poly(N-acylethyleneimine) in which t=2 in the above general formula (1) is obtained, and when 2-substituted-dihydro-2-oxazine is used, poly(N-acylpropyleneimine) in which t=3 in the above general formula (1) is obtained.

[0039] The poly(N-acylalkyleneimine) obtained by living polymerization of the cyclic iminoether (4) has a reactive group at the end. Therefore, the organopolysiloxane (AA) can be obtained by reacting the reactive group at the end of this poly(N-acylalkyleneimine) with the reactive groups (viii) to (xiii) of the modified organopolysiloxane represented by general formula (3).

[0040] The above-mentioned production method by living polymerization is effective in that the degree of polymerization can be easily controlled by the amounts of cyclic iminoether (4) and polymerization initiator used, as shown in the theoretical formula (II) below, and that a substantially monodisperse poly(N-acylalkyleneimine) having a narrower molecular weight distribution than that obtained by conventional radical polymerization can be obtained.

[0043] The weight average molecular weight of the modified organopolysiloxane represented by general formula (3) is preferably 15,000 to 220,000, more preferably 50,000 to 190,000, and even more preferably 70,000 to 170,000, from the viewpoints of the solubility of the resulting organopolysiloxane in polar solvents such as water and ease of handling after dissolution.

[0044] In addition, the functional group equivalent of the modified organopolysiloxane represented by general formula (3) has an upper limit in order to satisfy the mass ratio (a / b) and MWg of the organopolysiloxane (AA). From this viewpoint and from the viewpoint of imparting appropriate hydrophobicity to the main chain, the functional group equivalent is preferably 5000 to 40000, more preferably 10000 to 35000, and further preferably 15000 to 32000. Here, the functional group equivalent of the modified organopolysiloxane represented by general formula (3) is the weight average molecular weight of the modified organopolysiloxane represented by general formula (3) divided by the number of R groups that the modified organopolysiloxane has per molecule. 7 This is the value obtained by dividing the number of
