[0015] [ka]

[0016] (In the formula, R 1 represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms, and t represents 2 or 3. An organopolysiloxane comprising poly(N-acylalkyleneimine) segments bonded together, each of which comprises a repeating unit represented by the formula: The number average molecular weight of the poly(N-acylalkyleneimine) segment is 500 to 4000, the mass average molecular weight of the organopolysiloxane segment between adjacent poly(N-acylalkyleneimine) segments is 1,000 to 40,000; the mass average molecular weight of the organopolysiloxane segment constituting the main chain is 15,000 to 200,000; It is also possible to use organopolysiloxane (AA) in which the mass ratio (a / b) of the organopolysiloxane segment (a) constituting the main chain to the poly(N-acylalkyleneimine) segment (b) is 45 / 55 to 99 / 1.

[0017] At least two poly(N-acylalkyleneimine) segments are bonded to any silicon atom constituting the organopolysiloxane segment via an alkylene group containing a heteroatom. Furthermore, it is preferable that the poly(N-acylalkyleneimine) segment is bonded to one or more silicon atoms excluding those at both ends of the organopolysiloxane segment via the alkylene group, and it is more preferable that the poly(N-acylalkyleneimine) segment is bonded to two or more silicon atoms excluding those at both ends via the alkylene group. In other words, the organopolysiloxane of component (AA) is a graft polymer having, as side chains, at least two poly(N-acylalkyleneimine) segments consisting of repeating units represented by the general formula (1).

[0018] The alkylene group containing a hetero atom functions as a linking group for the poly(N-acylalkyleneimine) segment.

[0019] [ka]

[0020] In the N-acylalkyleneimine unit constituting the poly(N-acylalkyleneimine) segment, in general formula (1), R 1 In the formula (I), examples of the alkyl group having 1 to 3 carbon atoms include a linear alkyl group having 1 to 3 carbon atoms and a branched alkyl group having 3 carbon atoms, and specific examples thereof include a methyl group, an ethyl group, an n-propyl group, and an isopropyl group.

[0021] In general formula (1), t represents the number 2 or 3, and is preferably 2 from the viewpoint of availability of raw materials when producing organopolysiloxane.

[0022] The mass ratio (a / b) is in the range of 45 / 55 to 99 / 1. As the organopolysiloxane (AA), it is preferable to use a combination of an organopolysiloxane (A1) in which the mass ratio (a / b) of the organopolysiloxane segment (a) constituting the main chain to the poly(N-acylalkyleneimine) segment (b) is 45 / 55 to 72 / 28, and an organopolysiloxane (A2) in which (a / b) is 82 / 18 to 99 / 1, from the viewpoints of ensuring that the makeup lasts for a long time when sprayed after application, suppressing color transfer to the nonwoven fabric mask even when worn for a long time, suppressing a feeling of tightness and stickiness on the forehead immediately after application (spraying), and imparting a moist and lustrous feeling to the skin. 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 even after a long period of time has passed. Furthermore, 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.

[0023] 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 by H-NMR analysis from the integral ratio of alkyl or phenyl groups in the organopolysiloxane segment to methylene groups in the poly(N-acylalkyleneimine) segment.

[0024] 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.

[0025] In this specification, the term "organopolysiloxane segment between adjacent poly(N-acylalkyleneimine) segments" refers to the area 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 where one R 2 SiO unit and one R 3 and y+1 (R 2 )2SiO units. Also, the term "poly(N-acylalkyleneimine) segment" refers to a segment composed of the above R 3 -ZR binds to 4 This refers to

[0026] [ka]

[0027] In the above general formula (2), R 2 each independently represents an alkyl group having 1 to 22 carbon atoms or a phenyl group, and R 3 represents an alkylene group containing a heteroatom, -ZR 4 indicates 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.

[0028] 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 organopolysiloxane segments per mole of poly(N-acylalkyleneimine) segments. Note that when the functional groups of the modified organopolysiloxane raw material compound are 100% substituted with poly(N-acylalkyleneimine), this corresponds to the functional group equivalent (g / mol) of the modified organopolysiloxane.

[0029] 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 simply referred to as "GPC") measurement. In the present invention, this refers to the polystyrene-equivalent number average molecular weight (hereinafter simply referred to as "MNox") measured by GPC measurement under the measurement conditions described below. In order to produce a solid cosmetic preparation that has excellent moldability and elasticity, MNox is preferably in the range of 500 to 7000, more preferably 800 to 6500, and even more preferably 1000 to 6000.

[0030] The MWg can be calculated from the content (mass %) of organopolysiloxane segments constituting the main chain (hereinafter simply referred to as "Csi") using the following formula (I). MWg = Csi × MNox / (100-Csi) (I)

[0031] 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 viewpoints of the flexibility of the cosmetic and its adhesion to the skin. Furthermore, the organopolysiloxane (AA) can be easily incorporated into various products by dissolving it in a polar solvent such as water. Because the organopolysiloxane segment constituting the main chain shares a skeleton with the modified organopolysiloxane, which is the raw material compound, the MWsi is approximately the same as the weight-average molecular weight of the modified organopolysiloxane, which is the raw material compound. The weight-average molecular weight of the modified organopolysiloxane, which is the raw material compound, is measured by GPC under the measurement conditions described below and converted into polystyrene equivalents.

[0032] 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.

[0033] In addition to a high elastic modulus and large deformation capacity, organopolysiloxane (AA) has the characteristic thermoplasticity that when heated to temperatures in the range of 50 to 220°C, it becomes soft and its plasticity improves dramatically, and when heating is stopped and the temperature returns to room temperature, it quickly regains its elasticity.

[0034] The organopolysiloxane (AA) is, for example, a compound represented by the following general formula (3):

[0035] [ka]

[0036] (In the formula, R 2 has the same meaning as above, and R 5 and R 6 are R 2or the following formulas (viii) to (xiii):

[0037] [ka]

[0038] R represents a monovalent group represented by any one of 7 represents a monovalent group represented by the above formulas (viii) to (xiii), d represents a number of 91.5 to 1255.0, and e represents a number of 2.0 to 62.5. and a modified organopolysiloxane represented by the following general formula (4):

[0039] [ka]

[0040] (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 formula (I) with a terminally reactive poly(N-acylalkyleneimine) obtained by ring-opening polymerization of the cyclic imino ether represented by the formula (I).

[0041] 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 with strong electrophilic reactivity, for example, an alkyl ester of a strong acid such as an alkyl benzenesulfonate, an alkyl p-toluenesulfonate, an alkyl trifluoromethanesulfonate, an alkyl trifluoroacetate, or a dialkyl sulfate, can be used, and among these, a dialkyl sulfate is preferably used.

[0042] Examples of polymerization solvents 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. Of these, acetates are preferred. The amount of solvent used is usually 20 to 2,000 parts by mass per 100 parts by mass of the cyclic iminoether (4).

[0043] The polymerization temperature is usually 30 to 170°C, preferably 40 to 150°C, and the polymerization time varies depending on the polymerization temperature and the like, but is usually 1 to 60 hours.

[0044] For example, when a 2-substituted-2-oxazoline is used as the cyclic iminoether (4), a poly(N-acylethyleneimine) in which t=2 in the general formula (1) is obtained, and when a 2-substituted-dihydro-2-oxazine is used, a poly(N-acylpropyleneimine) in which t=3 in the general formula (1) is obtained.

[0045] The poly(N-acylalkyleneimine) obtained by living polymerization of the cyclic iminoether (4) has reactive groups at its terminals. Therefore, the organopolysiloxane (AA) can be obtained by reacting the reactive groups at the terminals of this poly(N-acylalkyleneimine) with the reactive groups (viii) to (xiii) contained in the modified organopolysiloxane represented by general formula (3).

[0046] 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.

[0047]

[0048] The amount of the cyclic iminoether (4) used and the amount of the polymerization initiator used are preferably such that MNi in formula (II) is 500 to 4,000, more preferably 800 to 3,500, and even more preferably 1,000 to 3,000.

[0049] 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.

[0050] Furthermore, 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 5,000 to 40,000, more preferably 10,000 to 35,000, and even more preferably 15,000 to 32,000. Here, the functional group equivalent of the modified organopolysiloxane represented by general formula (3) is the ratio of the weight-average molecular weight of the modified organopolysiloxane represented by general formula (3) to the number of R groups per molecule of the modified organopolysiloxane. 7 The value is calculated by dividing the number of

[0051] The amounts of the modified organopolysiloxane represented by general formula (3) and the terminally reactive poly(N-acylalkyleneimine) used are preferably such that the mass ratio (modified organopolysiloxane / terminally reactive poly(N-acylalkyleneimine)) is in the range of 45 / 55 to 99 / 1, from the viewpoint of the elastic modulus and deformability of the resulting organopolysiloxane.
