[Technical Field]
[0001] The present invention relates to a multi-component cosmetic composition and a multi-component hair dyeing or bleaching composition. [Background technology]
[0002] A wide variety of cosmetic products are known in terms of formulation and composition to provide various functions and effects in response to the diverse needs of users, and some cosmetic products are composed of multiple ingredients that are mixed together before use. For example, Patent Document 1 discloses a multi-component cosmetic that includes an oil-based cosmetic and an oil-in-water emulsion cosmetic, each containing specific ingredients, and is mixed at the time of use and applied to keratinous tissue, and aims to improve the fragrance that is given off after such mixing. Furthermore, Patent Document 2 discloses a cosmetic product for bleaching or dyeing hair, which comprises a first agent of a specific viscosity containing an alkaline agent and a second agent of a specific viscosity containing hydrogen peroxide, and in which the mixture of the first agent and the second agent contains specific components in a specific mass ratio, and which attempts to improve adhesion to the hair in the initial stage of application and make it easier to spread after a certain period of time has passed.

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-200285 [Patent Document 2] Japanese Patent Application Laid-Open No. 2016-113462 Summary of the Invention [Problem to be solved by the invention]
[0004] When applying such multi-component cosmetics to the skin, hair, etc., it is highly desirable that the cosmetics exhibit excellent adhesion so that they do not drip unnecessarily from the hands, applicators, the target, etc. when mixing them at the time of use or when applying them to the target, and that once applied, they spread well and can be applied smoothly to the target. However, since increasing adhesion to prevent unwanted dripping and realizing ease of spreadability depend on mutually contradictory physical properties, it is extremely difficult to fully achieve both of these in a multi-component cosmetic, even if simple viscosity control, etc. is implemented. For this reason, detailed investigations have yet to be fully conducted on any of the technologies described in the above patent documents, and this goal has yet to be achieved.
[0005] That is, the present invention relates to a multi-component cosmetic composition that combines physical properties that exhibit good adhesion to prevent dripping when mixed during use or when applied to keratinous tissues such as skin or hair, and physical properties that exhibit ease of spreadability after application.The present invention also relates to a multi-component hair dyeing or bleaching composition that, when applied to hair, exhibits excellent application properties that exhibit a good balance of adhesion, spreadability, and penetration in hair, while suppressing the noticeable unevenness of hair color and exhibiting excellent effect of hair color compatibility.

Furthermore, when hair is the target of application, the inventors have discovered that a multi-component hair dyeing or bleaching composition is a composition in which all components are mixed together at the time of use, and the composition comprises two components: an agent containing an ionic surfactant and a cationic polymer, and an agent containing a higher alcohol and a nonionic surfactant containing two specific surfactants in a specific mass ratio, and the mixture obtained by mixing all the components contains a specific amount of nonionic surfactant. This composition has excellent applicability, exhibiting a good balance of adhesion, spreadability, and penetration, while suppressing the noticeable unevenness of hair color, allowing for hair dyeing or bleaching with excellent compatibility with the hair color, and has led to the completion of the present invention.

[Effects of the Invention]
[0010] The multi-component cosmetic composition of the present invention exhibits good adhesion that effectively prevents unwanted dripping when the agents are mixed during use or when applied to keratinous tissue, and also exhibits excellent spreadability that makes it easy to spread and coat after application to keratinous tissue. This also promotes the penetration of the multi-component cosmetic composition of the present invention into keratinous tissue, allowing it to fully exert its desired effects on keratinous tissue. Furthermore, if a cosmetic kit is prepared that includes the above-mentioned multi-component cosmetic composition and a separate, independent treatment composition, the desired effects on keratinous tissue can be more effectively and practically exerted. Furthermore, when the multi-component hair dyeing or bleaching composition of the present invention is applied to hair, it exhibits excellent penetration and spreadability in hair, while effectively suppressing the conspicuousness of uneven hair color due to dyeing or bleaching, and exhibits excellent hair color compatibility from the roots to the ends, and from the surface to the inside of the hair strand, making it possible to dye or bleach hair to give a uniform hair color. DETAILED DESCRIPTION OF THE INVENTION
[0011] The present invention will be described in detail below. In the present invention, "adhesion" means the property of the composition to adhere firmly and tightly to the hand or applicator used, or the keratinous tissue to which it is applied, when the composition is applied, such as when the agent is applied to the keratinous tissue, thereby preventing unwanted dripping. Furthermore, "extendability" refers to the property of the composition to spread evenly over the surface of the application without being unevenly distributed in one part of the application area, and to the property of providing good spreadability and a smooth feel along the application direction. Furthermore, "penetration" means the property of the composition to reach from the surface to the inside of the hair bundle and to be evenly applied, particularly when the keratinous tissue is a hair bundle containing hair. Furthermore, "applicability" refers to the property of exhibiting three physical properties in a balanced manner: adhesion to keratinous tissues, spreadability, and penetration. Furthermore, "hair color compatibility" means that the composition does not become concentrated in certain areas such as the roots of the hair or the surface of the hair bundle, but spreads well and easily reaches every corner of the entire application area, including the ends of the hair and the inside of the hair bundle, thereby effectively suppressing the appearance of uneven hair color and expressing a hair color that is compatible and uniform throughout the entire application area, from the roots to the ends of the hair, and from the surface to the inside of the hair bundle. Also, "the roots of the hair" means the part where the hair grows out from the scalp, that is, the part close to the skin. Furthermore, "the difference in hair color is noticeable" means that the roots of hair dyed with hair dye have grown out, and the border between the dyed part and the hair color is noticeable, in other words, it is in a state of "pudding-like." The term "average number of moles added" refers to the average number of ethylene oxide units bonded to the activator molecule, and is a value determined by reverse phase liquid chromatography or size exclusion chromatography.
[0012] The multi-component cosmetic composition of the present invention is a multi-component composition comprising multiple components, including two components, component I and component II, which have different viscosities at at least 30°C, and is a composition in which, at the time of use, all of the components, including these two components, are mixed together in advance, and the mixture is applied to keratinous tissue. The keratinous tissue to which the multi-component cosmetic composition of the present invention is applied refers to the keratin-containing layer that protects the outermost layer on the body surface of mammals such as humans, and specifically includes skin, hair, body hair other than hair, toenails, fingernails, etc. Among keratinous tissues, from the viewpoint of fully enjoying the effects of the present invention, it is preferable to use the skin or hair, and it is more preferable to use the hair.
[0013] The multi-component cosmetic composition of the present invention contains at least two components, component I and component II, and may contain other components in addition to these two components. Thus, it may be a two-component cosmetic composition containing components I and II as components, or it may be a three-component cosmetic composition, four-component cosmetic composition, or five-component cosmetic composition that contains one or more components in addition to components I and II, or a cosmetic composition that contains five or more components.
[0014] The components I and II contained in the multi-component cosmetic composition of the present invention have different viscosities at 30°C, and the viscosity ratio of the viscosity of component II at 30°C to the viscosity of component I at 30°C (component II / component I) is 3 or greater. The multi-component cosmetic composition of the present invention comprises two components having this viscosity relationship, and also contains specific components (A) to (D) as described below, and is able to exhibit unique viscosity characteristics in the mixture obtained when all of the components are mixed. The reason why the composition of the present invention exhibits such effects is not clear, but is presumed to be as follows. The agents I and II of the multi-component cosmetic composition of the present invention have different viscosities at 30°C, and the viscosity ratio of the viscosity of agent II at 30°C to the viscosity of agent I at 30°C (agent II / agent I) is 3 or more, which increases the permeability of the mixture of agents I and II into keratinous tissues. Furthermore, a coacervate complex is formed during mixing of the mixture, and this complex causes the mixture obtained by mixing all of the constituent agents to penetrate the keratinous tissue at a shear rate of 0.0037 S. -1 Shear viscosity a and shear rate at 139S -1Since the ratio of shear viscosity a to shear viscosity b at shear viscosity a (shear viscosity a / shear viscosity b) is 5000 or more, it is presumed that the adhesion of the mixture is high and that when the mixture is subjected to shear, the viscosity decreases and extensibility increases. Furthermore, it is presumed that the mixture exhibits a good balance of the three physical properties of penetration into keratinous tissues, adhesion, and extensibility, which improves the ease of application to keratinous tissues, and when used as a hair coloring or hair bleaching composition, the composition can instantly penetrate deep into hair strands, easily achieving hair coloring or bleaching that exhibits excellent compatibility with the hair color.
[0015] The viscosity ratio of the viscosity of Agent II at 30°C to the viscosity of Agent I at 30°C (Agent II / Agent I) (the value obtained by dividing the viscosity of Agent II at 30°C by the viscosity of Agent I at 30°C) is, from the viewpoint of exhibiting good penetration into keratinous tissues, 3 or more, preferably 100 or more, more preferably 800 or more, even more preferably 1200 or more, still more preferably 1500 or more, and preferably 6000 or less, more preferably 5000 or less, even more preferably 4000 or less, and still more preferably 3000 or less. The viscosity ratio of the viscosity of Agent II at 30°C to the viscosity of Agent I at 30°C (Agent II / Agent I) is 3 or more, preferably 100 to 6000, more preferably 800 to 5000, even more preferably 1200 to 4000, and still more preferably 1500 to 3000.
[0016] The viscosity of agent I at 30°C should be lower than that of agent II so long as the above viscosity ratio is maintained, but is preferably 5000 mPa·s or less, more preferably 3000 mPa·s or less, and even more preferably 1 mPa·s or more.
[0017] The viscosity of component II at 30°C should be higher than that of component I so long as the above viscosity ratio is maintained, but is preferably 1000 mPa·s or more, more preferably 3000 mPa·s or more, even more preferably 5000 mPa·s or more, and preferably 50000 mPa·s or less, more preferably 40000 mPa·s or less, and even more preferably 30000 mPa·s or less.
[0018] The viscosity at 30°C refers to a value measured using a Brookfield viscometer, specifically, by the method described in the examples.
[0019] When using the multi-component cosmetic composition of the present invention, all of the components, including the two components I and II, are mixed in advance, and the resulting mixture is applied to keratinous tissue. The mixture obtained by mixing all of the components is subjected to a shear rate of 0.001 s measured with a rheometer at 25°C. -1 ~1000S -1 When the shear rate was changed to 0.0037S -1 Shear viscosity a and shear rate at 139S -1 The ratio of shear viscosity a to shear viscosity b at shear rate (shear viscosity a / shear viscosity b) is not less than 5000. Here, the rheometer is a rotational rheometer, and for example, an MCR301 manufactured by Anton Paar can be used to examine the shear rate dependency of the shear viscosity of the multi-component cosmetic composition of the present invention as a mixture obtained by mixing all of the constituent ingredients. The shear rate is 0.0037S. -1 Shear viscosity a and shear rate at 139S -1 Specifically, the ratio of shear viscosity a to shear viscosity b at a shear rate of 0.0037 S (shear viscosity a / shear viscosity b) is measured by the method described in the Examples. -1 The shear viscosity a and shear rate at 139 s -1 It means the value calculated by dividing the shear viscosity b at the time of the shear viscosity b by the shear viscosity b at the time of the shear viscosity b.
[0020] For example, the shear rate is 0.0037 S, which is the low speed range. -1Shear viscosity a at a shear rate of 139 S -1 A composition with a small ratio of shear viscosity a to shear viscosity b at a shear rate of 0.0037 (shear viscosity a / shear viscosity b) either has good adhesion but is difficult to spread, or has no adhesion but is easy to spread. On the other hand, when this ratio is very large, the composition has physical properties that provide excellent adhesion and good ease of spreading. Therefore, the multi-component cosmetic composition of the present invention has a shear rate of 0.0037 when the mixture obtained by mixing all of the constituent ingredients is -1 Shear viscosity a and shear rate at 139S -1 It is believed that the ratio of shear viscosity a to shear viscosity b at shear viscosity a (shear viscosity a / shear viscosity b) is 5000 or more, and this is due in part to the coacervate complex formed, which results in both good adhesion and excellent extensibility during use.
[0021] In the mixture, the shear rate is 0.0037 -1 Shear viscosity a and shear rate at 139S -1 From the viewpoint of exhibiting both good adhesion and excellent extensibility, the ratio of shear viscosity a to shear viscosity b at a shear rate of 0.0037 (shear viscosity a / shear viscosity b) is 5000 or more, preferably 6000 or more, more preferably 7000 or more, and preferably 20000 or less, more preferably 18000 or less, and even more preferably 10200 or less. -1 Shear viscosity a and shear rate at 139S -1 The ratio of shear viscosity a to shear viscosity b at shear viscosity a (shear viscosity a / shear viscosity b) is 5,000 or more, preferably 5,000 to 20,000, more preferably 6,000 to 18,000, and even more preferably 7,000 to 10,200.

[0025] However, in order to avoid imparting unique viscosity characteristics to the mixture, it is preferable to limit the content of anionic surfactants having a carboxyl group in the multi-component cosmetic composition of the present invention. Specifically, the content of anionic surfactants having a carboxyl group in the multi-component cosmetic composition of the present invention is preferably 0.45% by mass or less, more preferably 0.35% by mass or less, and even more preferably 0.10% by mass or less.

The agent II' may contain a nonionic surfactant other than the component (D-1) and the component (D-2) as the component (D). The total content of component (D), including components (D-1) and (D-2), in the total amount of the multi-component hair dyeing or bleaching composition of the present invention, i.e., the total content of component (D) relative to the total amount of the mixture obtained by mixing all the components, including Agents I' and II', is 100% by mass, i.e., the content of component (D) in the total amount of the mixture obtained by mixing all the components, is 1.63% by mass or more, preferably 2% by mass or more, more preferably 3% by mass or more, and preferably 6.5% by mass or less, more preferably 5.5% by mass or less, and even more preferably 4.5% by mass or less, from the viewpoint of sufficiently enhancing hair color compatibility.

[0106] In order to fully exert the highly useful hair dyeing or bleaching effect, it is preferable that Agent II' in the multi-component hair dyeing or bleaching composition of the present invention contains hydrogen peroxide, similar to that in the multi-component cosmetic composition described above. The content of hydrogen peroxide in agent II' is preferably 0.75% by mass or more, more preferably 1.5% by mass or more, and preferably 9% by mass or less, more preferably 7.5% by mass or less, and even more preferably 6% by mass or less.

[0107] In addition, in addition to components (C) and (D) and hydrogen peroxide, Agent II' contained in the multi-component hair dyeing or bleaching composition of the present invention may contain, as in the multi-component cosmetic composition described above, components (A), (B), (E), water, and other components commonly used as cosmetic raw materials, as appropriate, to the extent that the effects of the present invention are not impaired. However, with regard to the inclusion of component (B) in particular, from the viewpoint of effectively improving hair color compatibility while exhibiting excellent penetration and spreadability in hair, it is preferable that only Agent I' contains component (B) and that Agent II' does not contain component (B). When component (A) is contained in agent II', component (A-2) is preferred, and component (A-1) is preferably not contained. In this case, the content of component (A-2) in agent II' is preferably 0.1 mass% or more, more preferably 0.3 mass% or more, and preferably 1 mass% or less, more preferably 0.7 mass% or less.
[0108] From the viewpoint of sufficiently enhancing hair color compatibility, the mass ratio ((C) / (A)) of the content of component (C) to the content of component (A) in the multi-component hair dyeing or bleaching composition of the present invention is preferably 2 or more, more preferably 2.5 or more, even more preferably 2.6 or more, and preferably 5 or less, more preferably 4 or less, and even more preferably 3.2 or less.

Furthermore, in order not to inhibit the development of excellent penetration and spreadability in hair, the multi-component hair dyeing or bleaching composition of the present invention, like the above-mentioned multi-component cosmetic composition, preferably does not contain salicylic acid or acetaminophen, and more preferably does not contain either of these.
[0109] The content of component (E) in the multi-component hair dye or bleaching composition of the present invention is preferably 0.01% by mass or more, more preferably 0.1% by mass or more, even more preferably 0.3% by mass or more, and preferably 1.3% by mass or less, more preferably 1.2% by mass or less, and even more preferably 1.0% by mass or less. The content of component (E) in the multi-component hair dye or bleaching composition of the present invention is preferably 0.01 to 1.3% by mass, more preferably 0.1 to 1.2% by mass, and even more preferably 0.3 to 1.0% by mass.
[0110] Such a multi-component hair dyeing or bleaching composition of the present invention does not necessarily have to comprise two components that have different viscosities at 30°C and a specific viscosity ratio (component II / component I) as constituents, as in the above-mentioned multi-component cosmetic composition, and can exhibit excellent penetration and spreadability in hair while effectively suppressing the prominence of hair color differences and thereby exhibiting excellent hair color compatibility. However, the components I' and II' contained in the multi-component hair dyeing or bleaching composition of the present invention may also be two components that have the same viscosity ratio as the above-mentioned two components. In other words, in this case, the agent I contained in the multi-component cosmetic composition corresponds to the agent I' contained in the multi-component hair dyeing or bleaching composition, and the agent II contained in the multi-component cosmetic composition corresponds to the agent II' contained in the multi-component hair dyeing or bleaching composition, and the viscosity ratio of the viscosity of agent II at 30°C to the viscosity of agent I at 30°C (agent II / agent I) corresponds to the viscosity ratio of the viscosity of agent II' at 30°C to the viscosity of agent I' at 30°C (agent II' / agent I'). Similarly, the viscosity of agent I of the above multi-component cosmetic composition at 30°C corresponds to the viscosity of agent I' of the multi-component hair dye or bleaching composition at 30°C, and the viscosity of agent II of the above multi-component cosmetic composition at 30°C corresponds to the viscosity of agent II' of the multi-component hair dye or bleaching composition at 30°C. When Agent I' and Agent II' in the multi-component hair dye or bleaching composition of the present invention are two components having the same viscosity ratio as the two components described above, the viscosity ratio of Agent II' to Agent I' at 30°C (Agent II' / Agent I') (the value obtained by dividing the viscosity value of Agent II' at 30°C by the viscosity value of Agent I' at 30°C) is 3 or more, preferably 100 or more, more preferably 500 or more, even more preferably 1000 or more, and preferably 6000 or less, more preferably 2000 or less, and even more preferably 1500 or less, from the viewpoint of exhibiting excellent penetration and spreadability in hair while exhibiting excellent hair color compatibility. The viscosity ratio of Agent II' to Agent I' at 30°C (Agent II' / Agent I') is 3 or more, preferably 100 to 6000, more preferably 500 to 2000, and even more preferably 1000 to 1500.
[0111] In the components including Agent I' and Agent II' contained in the multi-component hair dye or bleaching composition of the present invention, the form of each component can be appropriately selected from the same form as the form of the component contained in the above-mentioned multi-component cosmetic composition. In particular, with regard to the forms of Agent I' and Agent II', from the viewpoint of exhibiting excellent penetration and spreadability in hair while also exhibiting excellent hair color compatibility, it is preferable that Agent I' be in the form of a liquid and Agent II' be in the form of a cream, and when obtaining a mixture of all the components, it is preferable to add Agent I' to at least Agent II' and mix them.
[0112] Thus, the multi-component hair dyeing or bleaching composition of the present invention exhibits excellent penetration and spreadability in the hair to which it is applied, while effectively suppressing the noticeable unevenness of hair color due to dyeing or bleaching, and exhibits excellent hair color compatibility from the roots to the ends and from the surface to the inside of the hair bundle, making it possible to dye or bleach hair with a uniform hair color. Therefore, this multi-component hair dyeing or bleaching composition is also highly useful as a hair dyeing method that includes applying the multi-component hair dyeing or bleaching composition to the roots of the hair and then spreading it to the ends. For example, specifically, if the roots to which the multi-component hair dyeing or bleaching composition is applied are roots where the difference in hair color is noticeable, the excellent hair compatibility can be fully realized.
[0113] The multi-component cosmetic composition of the present invention can be made into a cosmetic kit that separately and independently contains other agent compositions to be further applied to keratinous tissue after application of the multi-component cosmetic composition to keratinous tissue. That is, such a cosmetic kit of the present invention contains the above-mentioned multi-component cosmetic composition as well as other agent compositions to be applied separately and independently from the multi-component cosmetic composition. In this way, after the multi-component cosmetic composition of the present invention has been applied to keratinous tissue to fully exert its effects, further desired effects can be exerted by applying the other agent compositions to keratinous tissue. As with the above-described multi-component cosmetic composition, the multi-component hair dyeing or bleaching composition of the present invention can also be made into a cosmetic kit that further comprises, separately and independently, other agent compositions for application to keratinous tissue. Therefore, hereinafter, in relation to a cosmetic kit that comprises the multi-component hair dyeing or bleaching composition of the present invention and other agent compositions, the term "multi-component cosmetic composition of the present invention" will be read as "multi-component hair dyeing or bleaching composition of the present invention."
[0114] Examples of other compositions included in such a cosmetic kit include a moisturizer composition, a beauty serum composition, a coating composition, a sunscreen composition, a rinse composition, a conditioner composition, and a treatment composition. In particular, when the multi-component cosmetic composition of the present invention is a hair cosmetic composition intended for application to hair, preferably a hair bleaching or hair dyeing composition, a treatment composition is preferably included as the other composition included in the kit. Thus, by further applying such a treatment composition to hair after applying the multi-component cosmetic composition of the present invention as a hair cosmetic composition, it is possible to effectively suppress hair damage that tends to occur due to repeated application treatments, effectively increase the color density of the hair (also referred to as "deepening"), and also impart a good feel.
[0115] The treatment composition may be in an embodiment containing one constituent agent, specifically, for example, a rinse-off treatment agent, or a leave-in treatment agent. The treatment composition may also be in an embodiment containing multiple constituent agents, specifically, for example, a rinse-off treatment agent and a leave-in treatment agent, for a total of two constituent agents.

[0124] The treatment composition provided in the cosmetic kit of the present invention may contain only component (X1) of the above-mentioned component (X1) and component (X2), or may contain only component (X2).

[0125] Furthermore, when the treatment composition contains both component (X1) and component (X2), from the viewpoint of effectively suppressing hair damage while effectively increasing hair color intensity, it is preferable that the treatment composition comprises a total of two components: a rinse-off treatment and a leave-in treatment; it is more preferable that the rinse-off treatment contains component (X1) and component (X2), and that the leave-in treatment contains component (X2) without containing component (X1); and it is even more preferable that the component (X1) contained in the rinse-off treatment is component (x1-1).
[0126] More specifically, when the treatment composition provided in the cosmetic kit of the present invention comprises, as constituents, a rinse-off treatment containing component (X1) and component (X2), and a leave-in treatment containing component (X2) but not component (X1), the content of component (X1) in the rinse-off treatment is, relative to 100% by mass of the rinse-off treatment, preferably 0.5% by mass or more, more preferably 0.8% by mass or more, even more preferably 1.0% by mass or more, and preferably 1.8% by mass or less, more preferably 1.5% by mass or less, and even more preferably 1.2% by mass or less.

[0129] In the cosmetic kit of the present invention, a multi-component cosmetic composition is first applied to keratinous tissues, and then a treatment composition is applied to keratinous tissues. For example, in an embodiment in which the treatment composition comprises, as constituents, a rinse-off treatment agent containing component (X1) and component (X2) and a leave-in treatment agent containing component (X2) but not component (X1), the rinse-off treatment agent is applied to the keratinous tissues to which the multi-component cosmetic composition has been applied, and after rinsing, the leave-in treatment agent is applied to the keratinous tissues, and the keratinous tissues are then dried without rinsing. This can more effectively prevent hair damage and more effectively increase the color intensity of the hair.

[0137] The present invention will be described in detail below with reference to the following examples. Unless otherwise specified in the tables, the content of each component is expressed in mass %.
[0138] Test Example 1: Examples 1 to 8, Comparative Examples 1 to 7 Agent I and agent II were prepared according to the formulations shown in Table 1, and then agent I was added to agent II and mixed at a mass ratio of 1:2 (agent I:agent II). The resulting mixture was subjected to measurements and evaluations according to the following methods. The results are shown in Table 1.
[0139] <<Measurement of viscosity of agent I or agent II>> Using a Brookfield viscometer (TVB-10, manufactured by Toki Sangyo Co., Ltd.), the viscosity at 30°C was measured under the following measurement conditions selected appropriately depending on the form of the obtained agent I or agent II. Specifically, when the formulation was in liquid form, 90 g of each formulation was sampled and measured at a temperature of 30°C using rotor No. 1 at a rotation speed of 60 rpm for 1 minute. Note that if the measured value was below 10 mPa·s, that value was also used. On the other hand, when the formulation was in cream form, 45 g of each formulation was sampled and measured at a temperature of 30°C using a rotor TC at a rotation speed of 10 rpm for 1 minute. If the measured value was below 20,000 mPa·s, the value measured using a rotor TB at 10 rpm for 1 minute was used.
[0140] <<Measurement of Shear Viscosity of Mixtures>> The shear viscosity of the mixture obtained by mixing component I or component II was measured using an MCR301 manufactured by Anton Paar. 4 g of component II was weighed out into a 50 mL plastic cup, to which 2 g of component I was added and stirred with a plastic spatula for 30 seconds to obtain a mixture, which was then placed on the stage of the rheometer and clamped with a jig (approximately 0.7 g of the mixture was placed, and any excess mixture that spilled over was removed with a silicone spatula). Measurement began 3 minutes after mixing. Specifically, the obtained mixture was sandwiched between a plate and a jig (PP25, manufactured by Anton Paar) with a gap of 1 mm, and the shear rate was set to 0.001 s. -1 ~1000S -1 The shear rate was changed to 0.0037 S. -1 Shear viscosity a at a shear rate of 139 s -1 Next, based on the obtained values of shear viscosity a and shear viscosity b, the ratio between these (shear viscosity a / shear viscosity b) was calculated.
[0141] (i) Evaluation of Adhesion After mixing the first and second components, the mixture was left to stand for 5 minutes to stabilize the viscosity, and then the adhesion was evaluated. Specifically, 0.5 g of the mixture was placed on a glass plate, which was tilted 20° and left for 1 minute. The distance (mm) that the mixture moved from the place where it was placed was measured, and this was used as an index for evaluating the adhesion according to the following criteria. The larger the obtained value, the better the adhesion and the more effectively it can be evaluated as preventing unwanted dripping.
[0142] 5: The distance moved was less than 0.5 cm 4: The distance moved was 0.5 cm or more but less than 1 cm 3: The distance moved was 1cm or more but less than 2cm 2: The distance moved was 2cm or more but less than 3cm 1: The distance moved was 3cm or more
[0143] (ii) Evaluation of extensibility (ease of spreading) A 20 cm square piece of wool muslin was used as a test piece, and 0.5 g of the mixture obtained was applied to an area within 2 cm from one end of the test piece. The applied mixture was then spread with a finger toward the other end of the test piece, and the distance (cm) from one end was measured as the spreadable distance, and the spreadability (ease of spreading) was evaluated according to the following criteria.
[0144] 5: The spread distance from one end of the test piece was 12 cm or more 4: The spread distance from one end of the test piece was 10 cm or more but less than 12 cm. 3: The spread distance from one end of the test piece was 8 cm or more but less than 10 cm. 2: The spread distance from one end of the test piece was 6 cm or more but less than 8 cm. 1: The spread distance from one end of the test piece was less than 6 cm
[0145] (iii) Evaluation of permeability into keratinous tissue A panel of experts took about 3 g of the mixture and applied it three times over a distance of about 20 cm from the top of the head of a mannequin with medium-length hair, applying a force of about 600 g. This action was repeated twice. Next, using the tip of the handle of a standard ring comb (tail comb), the inside of a hair bundle approximately 5 cm from the top of the head was sliced (the operation of parting the hair bundle and opening the inside of the hair bundle), and the state of application of the mixture was visually confirmed, and its penetration into the keratinous tissue was evaluated according to the following criteria.
[0146] 4: The mixture is evenly applied to the inside of the hair strands 3: The mixture is uneven, but it is partially applied about halfway. 2: The mixture is unevenly applied, but in some places 1: No mixture applied to the inside of the hair strands
[0147] <<Overall evaluation of application properties>> The total value of the evaluation results obtained from the above "(i) Evaluation of adhesion," "(ii) Evaluation of spreadability (ease of application)," and "(iii) Evaluation of penetration into keratinous tissues" was calculated and used as an index for the overall evaluation of application properties.
[0148] <<Evaluation of texture>> A panel of experts applied 1 g of the mixture obtained to 1 g of gray hair tress (manufactured by Beaulux Co., Ltd.), and then performed a sensory evaluation of the feel (tactile sensation) of the mixture to the touch, using the degree of smoothness as an index according to the following criteria.
[0149] 4: Very smooth 3: Smooth 2: Slightly lacking in smoothness 1: Lack of smoothness
