Description

Technical Field

[0001] The present invention relates to a cosmetic or personal care product using a crosslinked organosiloxane polymer having specific rheological properties. Background Art

[0002] As a method for stably blending an oil agent such as silicone oil, hydrocarbon oil, or ester oil into a cosmetic or personal care composition, an organosiloxane polymer having a crosslinked structure has been proposed. These are well-known technologies, and various types of crosslinked organosiloxane polymers have been proposed. This crosslinked organosiloxane polymer is obtained, for example, by reacting a hydrosiloxane with a diene compound or a diallyl compound. At this time, this crosslinked organosiloxane polymer can also be produced by reacting in the oil agent or other solvents (Patent Documents 1 to 7).

[0003] These crosslinked organosiloxane polymers are also known to provide high thixotropy, and are also known to contribute to a thickening effect or stability to cosmetics, and to give a non-greasy film thickness feeling after application. However, due to the excessive thixotropy, the viscosity change during the application of force is significant, and when applying to the skin, a sharp viscosity drop occurs, so there is also a problem that the user feels a lack of smoothness at the initial stage of application. In addition, these crosslinked organosiloxane polymers are resinous or high-viscosity gum-like, and are highly elastic solids, so during the application process, it is sometimes difficult to spread or feel heavy on the skin. Moreover, since the crosslinked organosiloxane polymer is resinous or high-viscosity gum-like and is a highly elastic solid, it is difficult to uniformly blend into the cosmetic in its original state, and it is necessary to pre-mix with a part of the oil agent blended in the cosmetic to make it in a liquid, paste, or gel state, and there are also problems in terms of usability.

[0004] In order to solve the above problems, a liquid organopolysiloxane having a micro-crosslinked structure has been proposed (Patent Document 8). Since the liquid organopolysiloxane described in Patent Document 8 is liquid, it is easily miscible with other liquid oils and can be easily and uniformly and stably mixed, but there is still room for improvement in terms of touch. In Patent Document 9, a method for improving the touch or uniformity by specifying the range of the loss coefficient tanδ when the shear frequency of the liquid organopolysiloxane is 10 Hz has also been proposed (Patent Document 9). However, during the application process of the cosmetic, the constantly changing touch changes cannot be completely captured, and it cannot be said that the problem has been solved.

[0016] Problems to be Solved by the Invention

[0017] The present invention has been completed in view of the above problems, and an object thereof is to improve the touch during application by blending a crosslinked organosiloxane polymer that is non-fluid at 25°C and has specific rheological properties into a cosmetic.

[0018] Solutions for Solving the Problems

[0019] The inventors of the present invention conducted intensive studies to achieve the above object, and as a result, found that the object can be achieved by an organosiloxane polymer having specific rheological properties, and thus completed the present invention. That is, it was found that by blending a crosslinked organosiloxane polymer that is non-fluid at 25°C, has a crosslinked structure containing a carbon-silicon bond, and has a loss coefficient (Tδ) of 1.1 or less when the shear frequency is 1 Hz and a loss coefficient of 0.9 to 1.4 when the shear frequency is 10 Hz under the conditions of a measurement temperature of 25°C and a shear strain of 10% into a cosmetic, the above object can be achieved.

[0020] If it is a crosslinked organosiloxane polymer having the above rheological properties, after applying the cosmetic, not only can a moderate film thickness feeling without stickiness be obtained, but also a high satisfaction accompanied by smoothness or good adhesion can be obtained at the start or during the application.

[0021] The crosslinked organosiloxane polymer of the present invention is characterized by having specific rheological properties. The crosslinked organosiloxane polymer, in addition to having a crosslinked structure containing carbon-silicon bonds, as long as it is non-flowable at 25 °C and satisfies the rheological properties of the present invention, there are no particular restrictions on the types of functional groups and the molecular structure of the polymer.

The organohydrogenpolysiloxane has 2 to 10,000 silicon atoms, and each molecule of the organohydrogenpolysiloxane has 1.01 to 10 hydroxyl groups. Preferably, the alkenyl-containing compound has a weight average molecular weight of 50 to 9,000,000, and each molecule of the alkenyl-containing compound has 1.01 to 10 alkenyl groups. By using such organohydrogenpolysiloxane and alkenyl-containing organic compound, it is easy to adjust the crosslinking degree of the obtained crosslinked organosiloxane polymer and obtain specific rheological properties.

[0035] It is preferred that the alkenyl group-containing organic compound is one or more alkenyl group-containing compounds selected from the following component (A2), component (A3), component (A4) and component (A5).

[0058] Moreover, the crosslinked organosiloxane polymer of the present invention is more easily compounded into a cosmetic by being uniformly mixed in advance with an oil agent that is liquid at 25°C.

[0059] Advantages of the Invention

[0060] The cosmetic compounded with the crosslinked organosiloxane polymer of the present invention is a cosmetic that improves the touch obtained during application. It is expected to provide a cosmetic with good touch such as moderate smoothness, adhesion, and a uniform film thickness feeling from the initial stage of application to after application. For example, it is suitably compounded into skin care products, makeup products, anti-ultraviolet products, hair products, antiperspirant products, deodorant products, etc. Detailed Description of the Invention

[0061] Hereinafter, the present invention will be described in more detail.

[0062] (A) Crosslinked organosiloxane polymer

[0063] The crosslinked organosiloxane polymer of the present invention is characterized by being non-flowable at 25°C. In the present invention, "being non-flowable" means that the following solid-liquid determination test is performed and the result is judged as a solid.

[0064] [Solid-Liquid Determination]

[0065] Mark lines at the heights of 25 mm and 40 mm from the bottom of a 20 ml glass screw tube (LABORAN screw tube bottle NO.5 manufactured by AS ONE Corporation, bottle body diameter 27 mm), and inject the sample up to the 25 mm mark line. Next, seal it and leave it standing and keep it warm in a constant temperature bath at 25°C for 24 hours. After that, lay the screw tube horizontally, and judge the sample whose front end reaches the 40 mm mark line within 96 hours as "liquid", and judge the sample that does not reach as "solid".

[0066] In addition, the crosslinked organosiloxane polymer of the present invention is characterized by having a crosslinked structure containing carbon-silicon bonds, and when measured at a measurement temperature of 25°C, a shear strain of 10%, and changing the shear frequency, the loss coefficient at a shear frequency of 1 Hz is 1.1 or less, and the loss coefficient at a shear frequency of 10 Hz is 0.9 to 1.4. The loss coefficient is also called the loss tangent and is represented by Tanδ. This value is obtained from the ratio G” / G’ of the storage modulus (G’) to the loss modulus (G”), and represents how much energy is absorbed or converted into heat when the object is deformed. In addition, the loss coefficient can be measured by a dynamic viscoelasticity measuring device. There are several types of dynamic viscoelasticity measuring devices for applying vibration strains such as tension, compression, bending, and shear to an object to obtain various parameters. The type of dynamic viscoelasticity measuring device is selected according to the shape or purpose of the object, but the loss coefficient of the present invention is a value obtained by a rotational rheometer. When measuring, as the set strain value, if it is within the range of 0.01 to 10%, there is not much change, but it is preferably 1 to 10%. In this application, a strain value of 10% is used as the measurement condition.

[0067] In addition, when measuring, as the set gap, if it is within the range of 0.2 to 1.5 mm, there is not much change, but it is preferably 0.5 to 1.0 mm. In this application, a gap of 0.5 mm is used as the measurement condition.

[0068] Generally speaking, in the case of a viscoelastic material, the stronger the elasticity, the smaller the loss coefficient. Such materials mainly have a three-dimensional crosslinked structure. On the other hand, in the case of a material with strong viscosity, especially a material with fluidity, the loss coefficient becomes larger. In the case of a low-viscosity liquid with a linear structure, since no torque is applied, the loss coefficient cannot be measured. When the value of the loss coefficient is around 1, it is a state where the balance between elasticity and viscosity is well balanced.

[0069] The organosiloxane polymer of the present invention preferably has a moderately low crosslinking density, or may have a crosslinked structure in a part of the structure. The organosiloxane polymer with well-controlled crosslinking density has the above-mentioned loss coefficient within this range, and can achieve a state where the balance between elasticity and viscosity is well balanced.

[0070] Although the loss coefficient of the crosslinked organosiloxane polymer of the present invention is 1.1 or less at a shear frequency of 1 Hz, up to a certain shear frequency value, the loss coefficient has a tendency to increase as the shear frequency increases. When comparing the loss coefficients at 1 Hz and 10 Hz, the value measured at 10 Hz has a slightly larger tendency, which indicates that as the shear frequency increases, the repulsive force becomes smaller.

[0071] When the loss factor at a shear frequency of 1 Hz is greater than 1.1 and the loss factor at a shear frequency of 10 Hz is greater than 1.4, the polymer has fluidity. When compounded in a cosmetic, the smoothness becomes excessive, so the sticky touch is uncomfortable, or it is difficult to feel a sufficient film thickness. On the other hand, when the loss factor at a shear frequency of 1 Hz is 1.1 or less and the loss factor at a shear frequency of 10 Hz is less than 0.9, the elasticity becomes strong, and when compounded in a cosmetic, good smoothness cannot be obtained, and there is a tendency to feel difficult to apply.

[0072] In the present invention, the structure of the crosslinked organosiloxane polymer is not particularly limited as long as it has a crosslinked structure containing a carbon-silicon bond as described above.

[0073] Preferably, the crosslinked organosiloxane polymer is a hydrosilylation reaction product of one or more organohydrogenpolysiloxanes and one or more alkenyl-containing organic compounds. The organohydrogenpolysiloxane has 2 to 10,000 silicon atoms, and each molecule of the organohydrogenpolysiloxane has 1.01 to 10 hydroxyl groups. Preferably, the alkenyl-containing compound has a weight average molecular weight of 50 to 9,000,000, and each molecule of the alkenyl-containing compound has 1.01 to 10 alkenyl groups. More preferably, the organohydrogenpolysiloxane has 3 to 5,000 silicon atoms, and each molecule of the organohydrogenpolysiloxane preferably has 1.01 to 8 hydroxyl groups, and more preferably has 1.01 to 5 hydroxyl groups. The alkenyl-containing compound preferably has a weight average molecular weight of 50 to 900,000, and each molecule of the alkenyl-containing compound preferably has 1.01 to 8 alkenyl groups, and more preferably has 1.01 to 5 alkenyl groups.

[0074] In addition, in the present invention, the weight average molecular weight of the organopolysiloxane is measured by GPC (gel permeation chromatography) analysis using polystyrene as a standard substance. However, for example, in the case of pentadiene, octadiene, decadiene, etc. which are olefins equivalent to the above (A4) and can be calculated from the structure, the molecular weight calculated from the structure is used instead of the weight average molecular weight.

[0075] In the range where the number of hydroxyl groups per molecule of the above-mentioned organohydrogenpolysiloxane is 1.01 to 10, in addition to the organohydrogenpolysiloxane having 2 or more hydroxyl groups per molecule, the organohydrogenpolysiloxane having only 1 hydroxyl group per molecule can be arbitrarily included. Further, in the range where the number of alkenyl groups in one molecule of the above-mentioned alkenyl-containing organopolysiloxane satisfies 1.01 to 10, in addition to the alkenyl-containing organopolysiloxane having 2 or more alkenyl groups per molecule, the alkenyl-containing organopolysiloxane having only 1 alkenyl group per molecule can be arbitrarily included. That is, when the total number of hydroxyl groups of the organohydrogenpolysiloxane is less than 2 on average per molecule of the organohydrogenpolysiloxane, the crosslinkable organohydrogenpolysiloxane and the non-crosslinkable organohydrogenpolysiloxane coexist. Similarly, when the number of alkenyl groups in the alkenyl-containing organic compound is less than 2 on average per molecule of the alkenyl-containing organic compound, the crosslinkable alkenyl-containing organic compound and the non-crosslinkable alkenyl-containing organic compound coexist.

[0076] The specific rheological properties of the polymer of the present invention can be obtained by the above-mentioned crosslinked polymer. The crosslinking degree needs to be appropriately adjusted according to the type of the organohydrogenpolysiloxane or the alkenyl-containing organic compound. In addition, a plurality of organohydrogenpolysiloxanes or alkenyl-containing compounds can be combined as needed. According to the research results of the inventors of the present invention, it is considered that the fewer the number of crosslinking points obtained by the hydrosilylation reaction, the better. Therefore, if the total number of hydroxyl groups participating in the formation of the crosslinked structure is more than 10 per mole of the organohydrogenpolysiloxane, the resulting polymer becomes hard and may become a powdery substance without cohesiveness. In addition, if the total number of hydroxyl groups is less than 1.01 per mole of the organohydrogenpolysiloxane, there is almost no crosslinked structure, and it may become a liquid with a large loss factor or a low viscosity that cannot be measured. The same applies to the alkenyl-containing compound. If the total is 10 or more on average per mole, the polymer becomes hard. If it is less than 1.01 on average per mole, the possibility of becoming a liquid may increase. In addition, the number per mole in the case of using two or more organohydrogenpolysiloxanes is calculated by the following method.

[0077] For example, when 1 mole of an organohydrogenpolysiloxane having 2 hydroxyl groups in the structure and 0.5 mole of an organohydrogenpolysiloxane having 5 hydroxyl groups in the structure are used in combination, the number of hydroxyl groups per mole of the organohydrogenpolysiloxane is calculated to be 3.0. Similarly, in the case of the alkenyl-containing organic compound, it is calculated by the same method.

[0078] The structure of the crosslinked organosiloxane polymer only needs to be composed of a crosslinked structure containing carbon-silicon bonds, and there is no particular limitation. For example, it is preferably a reactant of one or more organohydrogenpolysiloxanes (A1) selected from the compounds represented by the following and one or more alkenyl-containing organic compounds selected from the following (A2), (A3), (A4), and (A5).

[0171] As surfactants, there are nonionic, anionic, cationic, and amphoteric surfactants, but there is no particular limitation as long as they are surfactants used in ordinary cosmetics. Among these surfactants, the following surfactants with a structure different from the above component (A) are preferred: crosslinked polyether-modified silicone, crosslinked polyglycerol-modified silicone, linear or branched polyoxyethylene-modified organopolysiloxane, linear or branched polyoxyethylene-polyoxypropylene-modified organopolysiloxane, linear or branched polyoxyethylene-alkyl co-modified organopolysiloxane, linear or branched polyoxyethylene-polyoxypropylene-alkyl co-modified organopolysiloxane, linear or branched polyglycerol-modified organopolysiloxane, linear or branched polyglycerol-alkyl co-modified organopolysiloxane, linear or branched pyrrolidone-modified organopolysiloxane.

[0172] Among the surfactants, it is preferred that the content of hydrophilic polyoxyethylene groups, polyoxyethylene-polyoxypropylene groups, or polyglycerol residues accounts for 10 to 70% by mass in the molecule.

[0173] In the case of using crosslinked organopolysiloxanes such as crosslinked polyether-modified silicone and crosslinked polyglycerol-modified silicone, in a composition composed of the crosslinked organopolysiloxane and an oil agent that is liquid at room temperature, the crosslinked organopolysiloxane preferably swells with respect to the liquid oil containing its own weight or more of the liquid oil agent. As the liquid oil agent, liquid silicone, hydrocarbon oil, ester oil, natural animal and vegetable oil, semi-synthetic oil, etc., and fluorine-based oil in the oil agent of component (B) can be used. For example, 0.65 to 100 mm 2 / s (25 °C) low-viscosity silicone, liquid paraffin, squalane, isododecane, isocetane and other hydrocarbon oils, or glyceride oils such as glyceryl trioctanoate, ester oils such as isocetyl isononanoate, N-acyl glutamate, lauroyl sarcosinate, and natural animal and vegetable oils such as macadamia nut oil can be cited.

[0176] The blending amount of the surfactant is preferably 0.1 to 20% by mass of the whole cosmetic. If it is 0.1% by mass or more, the functions of dispersion or emulsification can be fully exerted. If it is 20% by mass or less, there is no concern that the cosmetic becomes sticky in terms of usability, so it is preferred. The HLB of the surfactant is not limited, but for the purpose of maintaining the water resistance of the cosmetic, it is preferably 2 to 14.5.

[0220] <Cosmetics>

[0221] The crosslinked organosiloxane polymer in the present invention can be blended into cosmetics for various uses. In particular, it can be used as a raw material for all cosmetics applied externally to the skin or hair. The blending amount of the crosslinked organosiloxane polymer into the cosmetics is not particularly limited and can be appropriately adjusted according to the type or purpose of the cosmetics, etc. For example, it is preferably in the range of 0.01 to 95% by mass of the whole cosmetics, more preferably 0.05 to 80% by mass, and further preferably 0.1 to 50% by mass. By blending the crosslinked organosiloxane polymer in this amount, a cosmetic with good usability can be obtained.

[0222] The form of the cosmetic can be any one of an emulsion type, a non-aqueous type, and an aqueous type. When a moist feeling upon use is desired, an emulsion form may be selected. As the emulsion form, it may be any one of an O / W type emulsion, a W / O type emulsion, an O / W / O type emulsion, and a W / O / W type emulsion. When an oily feeling or water resistance is desired, a non-aqueous composition or a powder composition may be selected. When a refreshing feeling upon use is desired, an aqueous composition may be selected. In the present invention, a good cosmetic can be obtained in any form. Further, in the present invention, the "non-aqueous composition" means a composition that is not intentionally admixed with water, and the "aqueous composition" means a composition that is not intentionally admixed with an oily component. Among them, a W / O type emulsion or a non-aqueous composition that can be expected to have particularly high thickening property is preferred. As the W / O type emulsion, there are mentioned a two-layer separation type that is sufficiently shaken before use and a non-separation type that can be used directly without shaking.

[0223] There are several types of the two-layer separation type, but in a broad sense, it means a separation type in which an emulsified composition or dispersion separates into a plurality of phases upon standing. For example, there are a separation type that separates into two layers of a layer containing a powder and an emulsion layer upon standing, a separation type that separates into two layers of a layer containing a powder and an oil layer, a separation type that separates into two layers of a water layer and an oil layer, a separation type in which a part of the emulsion layer and the water layer are separated, a separation type in which a part of the emulsion layer containing a powder and the water layer are separated, a separation type in which a layer composed of a powder and an oil layer component and the water layer are separated, and the like. It is characterized in that it is immediately emulsified and dispersed or becomes a dispersed single layer immediately after shaking. Further, in order to facilitate mixing during shaking, there is a preparation in which a stainless steel ball is placed in a container. These two-layer separation types include a two-layer type, a shaking type, a rattling type, and the like. As the W / O type emulsion, the effect of the present invention is better exhibited in the two-layer separation type that is sufficiently shaken before use or the non-separation type that can be used directly without shaking. In terms of usability, the non-separation type that does not require shaking is preferred.

[0224] The cosmetic containing a crosslinked organosiloxane polymer of the present invention can be prepared by various known methods. Further, it can also be mixed with the above-mentioned oil agent, ultraviolet absorber, and powder. In the case of an emulsified composition, it can be mixed into the oil phase before emulsification, or the emulsified product after emulsification, or both. The mixing may be carried out at room temperature or under heating. The mixing method is not particularly limited, and a pulsator, a propeller mixer, a paddle mixer, a disperser, a homo-mixer, a roll mixer, a Henschel mixer, an atomizer, a needle mill, a revolution / rotation type mixer, or the like can be used.

[0225] There are no particular limitations on the cosmetics, and for example, they can be applied to various products such as skin lotions, milky lotions, creams, hair care products, foundations, makeup bases, sunscreens, concealers, blushes, lipsticks, lip glosses, balms, mascaras, eyeshadows, eyeliners, body makeup, deodorants, nail cosmetics, etc. Among them, emulsion, cream, hair care products, foundation and other color cosmetics or cosmetics with sunscreen effect are particularly preferred. As the properties of the cosmetics of the present invention, various properties such as liquid, cream, solid, paste, gel, mousse, spray, clay, powder, stick, etc. can be selected.
