Description

[Technical Field]

[0001] The present invention relates to a multi-component hair treatment agent and a method for using the same, and more particularly to a multi-component hair treatment agent comprising an agent containing an anionic silicone and an agent containing a cationic component, and a method for using the same. [Background technology]

[0002] Since hair quality varies from person to person, there is a demand for hair quality that is easier to manage in daily life, such as when hair quality is difficult to manage, and the like. As a technology for changing hair quality as needed in this way, the following Patent Document 1 is known. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2023-163406 Summary of the Invention [Problem to be solved by the invention]

[0004] It is known that hair quality changes due to factors such as lifestyle changes, stress, childbirth, and aging. Among these changes in hair quality, individual hairs can become uneven or twisted, making them difficult to handle and frizzing, making them hard to manage in daily life. There is a demand for improvements to the feel and manageability caused by these hair changes.

[0005] The above-mentioned Patent Document 1 discloses a hair treatment agent, a multi-component hair treatment agent, and a hair treatment method, which contain A, which is at least one member selected from the group consisting of a1 (a heterocyclic compound having a sulfonyl group-constituting S atom in the ring skeleton, or a salt thereof), a2 (a steviol glycoside or a derivative thereof), a3 (a fructan or a derivative thereof), a4 (a monosaccharide alcohol or a disaccharide alcohol), and a5 (aromatic sulfonic acid or a salt thereof), and B, which is a reducing agent, with the aim of improving the difficulty of managing hair caused by unevenness due to changes in hair quality (Patent Document 1

[0008] ). The technology of Patent Document 1 is an excellent technology in terms of improving the difficulty of managing hair caused by unevenness due to changes in hair texture, but it requires the use of a reducing agent. In this regard, it is possible that a reducing agent cannot be used depending on the formulation, or even if it can be used, it may not be possible to incorporate a sufficient amount. Therefore, if there are more options that can realize the improvement of the feel and difficulty of managing caused by changes in hair, it will be possible to select a formulation with greater flexibility.

[0006] The present invention has been made in view of the above-mentioned circumstances, and aims to provide a multi-component hair treatment agent and a method for using the same that improves the feel and difficulty in handling caused by changes in hair through a configuration different from conventional ones. [Means for solving the problem]

[0007] While addressing the issue of improving the feel and difficulty of management caused by hair changes, the inventors discovered that the feel and manageability of hair can be significantly improved by using a hair treatment agent containing an anionic silicone in combination with a hair treatment agent containing a cationic component, while Patent Document 1 states that the unevenness of hair exceeds the size that can be alleviated by a coating agent (Patent Document 1

[0010] ), and completed the present invention. This creates a different aspect from the above-mentioned prior application, i.e., it creates a wider range of options and improves the flexibility of treatment.

[0008] The present invention includes the following: [1] A multi-component hair treatment composition comprising multiple hair treatment compositions including the following agent (A) and the following agent (B): Agent (A): A hair treatment agent containing anionic silicone Agent (B): A hair treatment agent containing a cationic component [2] The multi-component hair treatment composition according to the above [1], wherein the anionic silicone has a carboxy group. [3] The multi-component hair treatment composition according to [1] or [2] above, which contains a cationic silicone as the cationic component. [4] The multi-component hair treatment composition according to any one of [1] to [3] above, wherein the agent (B) is a hair treatment composition to be applied to hair to which the agent (A) has been applied. [5] The multi-component hair treatment composition according to any one of [1] to [4] above, wherein the agent (B) is a hair treatment composition to be applied to the hair in the presence of the agent (A). [6] A method for using the multi-component hair treatment agent described in [1] above, comprising: an agent (A) application step of applying the agent (A) to hair; and an agent (B) application step of applying the agent (B) to hair, A method for using a multi-component hair treatment composition, wherein the step of applying agent (B) is a step that follows the step of applying agent (A). [7] The method for using the multi-component hair treatment composition according to [6] above, wherein the hair in the agent (B) application step is hair on which the agent (A) applied in the agent (A) application step remains. [8] The anionic silicone contained in the agent (A) applied in the agent (A) application step is T A (g), and the cationic component contained in the agent (B) applied in the agent (B) application step is T B (g), the ratio of these (T A / T B ) is 0.01 to 50. [Effects of the Invention]

[0009] The multi-component hair treatment composition of the present invention has a structure different from conventional ones, which can improve the feel and difficulty in handling caused by changes in hair. According to the method of using the multi-component hair treatment composition of the present invention, the feel and difficulty in handling caused by changes in hair can be improved by using a constitution different from that of conventional methods. DETAILED DESCRIPTION OF THE INVENTION

[0010] The present invention will be described in detail below. Unless otherwise specified, "%" means "% by mass", "parts" means "parts by mass", and the notation "X to Y" means "at least X and at most Y". In addition, for the names of some compounds, names based on the Japan Cosmetic Industry Association's ingredient labeling list or INCI (International Nomenclature of Cosmetic Ingredients) will be used. Furthermore, in the names of some compounds, polyoxyalkylene chains are sometimes abbreviated as "POE" for polyoxyethylene chains and "POP" for polyoxypropylene chains. The numbers in parentheses following these abbreviations indicate the number of moles added. Furthermore, (meth)acrylic acid refers to acrylic acid or methacrylic acid.

[0011] [1] Multi-drug hair treatment agent The hair treatment composition of the present invention comprises multiple hair treatment compositions including agent (A) (hereinafter simply referred to as "agent A") and agent (B) described below (hereinafter simply referred to as "agent B").

[0012] (1) Agent A Agent A is a hair treatment agent containing anionic silicone. Anionic silicone is a silicone that can exhibit anionic properties in the presence of water. Anionic silicone may exhibit the above properties by any mechanism, but by having an anionic group, it can function as an anionic silicone. Anionic groups are groups that can exhibit anionic properties in an environment where water is present. That is, examples of anionic groups include acidic groups such as carboxyl groups, sulfonic acid groups, phosphate groups, and modified groups having these groups. These may be used alone or in combination of two or more.

[0013] Among the above-mentioned anionic groups, the anionic silicone contained in Agent A is preferably an anionic silicone having a carboxy group (including a modified group having a carboxy group) from the viewpoint of the magnitude of the effect of improving the feel and difficulty in handling caused by hair changes. The carboxy group may be derived from any compound, for example, pyrrolidone carboxylic acid, acrylic acid, methacrylic acid, crotonic acid, benzoic acid, itaconic acid, maleic acid, fumaric acid, oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid, azelaic acid, sebacic acid, isophthalic acid, terephthalic acid, and salts thereof. These may be used alone or in combination of two or more. The anionic group may be provided on a side chain of the silicone, on the terminal of the siloxane bond main chain that constitutes the silicone, or both. Of these, it is preferable to provide the anionic group on a side chain, from the viewpoint of increasing the contribution of the anionic group.

[0014] Specific examples of anionic silicones include anionic silicones having a pyrrolidone carboxylic acid residue such as PCA dimethicone and bisPCA dimethicone, and anionic silicones having a carboxydecyl residue such as carboxydecyl dimethicone and biscarboxydecyl dimethicone.

Among the above, from the viewpoint of the magnitude of the effect of improving the feel and difficulty in handling caused by hair changes, the component A in the multi-component hair treatment composition of the present invention is preferably an anionic silicone having a pyrrolidone carboxylic acid residue, and more preferably PCA dimethicone. An example of this PCA dimethicone is one in which a methyl group in dimethylpolysiloxane is bonded to a nitrogen atom constituting a five-membered heterocyclic ring of pyrrolidone carboxylic acid via an ethylene group (-CHCH-). It is preferable that the agent A does not contain the cationic component contained in the agent B.

In other words, it is a compound in which dimethylpolysiloxane (including linear and cyclic) is modified with an amino group or a monovalent group having an amino group. The above description of amino modification is intended to explain the chemical form and does not specify the manufacturing method, i.e., it does not matter whether the product is actually manufactured by substituting amino groups or the like for the methyl groups of dimethylpolysiloxane.

[0018] Furthermore, the amino-modified silicone may be modified in addition to the modification for introducing an amino group.

These may be used alone or in combination of two or more.

[0060] (5) Dosage form The formulation (formulation at 25°C) of each of Agents A and B constituting the multi-component hair treatment agent is not limited, and can be, for example, liquid or solid. When the agent is liquid, it may be a viscous liquid or a non-viscous liquid. Viscous forms include, for example, cream, paste, and gel. Non-viscous forms include, for example, aqueous solutions, emulsions (OW emulsions, WO emulsions, multiple emulsions), and foams (mousses). Solid forms include, for example, powders, granules, and gels. Each agent may be handled using any packaging material, and known packaging materials can be used as appropriate. For example, the agent can be dispensed from a pump, mist container, mousse container, or the like, and can be a pump-type, mist-type, or mousse-type product. In the multi-component hair treatment composition, components A and B are preferably in a liquid form, more preferably in a viscous liquid form, and even more preferably in a cream form. In this case, it is preferable that the components are packaged in a tube container as a tube-type product, or in a pump container as a pump-type product.

[0061] When agent A and / or agent B constituting the multi-component hair treatment composition are in a non-viscous liquid form, the lower limit is not limited, but can be, for example, 1 mPa·s or more, further 10 mPa·s or more, or even 50 mPa·s or more, and the upper limit is not limited, but can be, for example, 10,000 mPa·s or less, further 5,000 mPa·s or less, or even 2,500 mPa·s or less. These upper and lower limit values ​​can be combined arbitrarily. That is, for example, the viscosity can be 1 to 10,000 mPa·s, 10 to 5,000 mPa·s, or 50 to 2,500 mPa·s. If Agent A and / or Agent B are non-viscous liquids (viscosity less than 5,000 mPa·s), the viscosity is measured using a Brookfield viscometer at 25°C using a No. 3 rotor at a rotation speed of 12 rpm for a measurement time of 60 seconds.

[0062] When agent A and / or agent B constituting the multi-component hair treatment composition are in a viscous liquid form, the lower limit can be 1,000 mPa·s or more, further 3,000 mPa·s or more, further 5,000 mPa·s or more, further 10,000 mPa·s or more, or even 20,000 mPa·s or more, and the upper limit is not limited, but can be 70,000 mPa·s or less, further 50,000 mPa·s or less, further 35,000 mPa·s or less, further 30,000 mPa·s or less, or even 25,000 mPa·s or less. These upper and lower limit values ​​can be combined in any desired manner. In particular, Agent A and Agent B can be viscous liquids with different viscosities. In particular, by making Agent B's viscosity higher than that of Agent A, each agent can be applied evenly, improving the manageability of the finished hair. Specifically, when Agent B's viscosity is higher than that of Agent A, the viscosity of Agent A can be 1,000 to 35,000 mPa·s, 3,000 to 30,000 mPa·s, or 5,000 to 25,000 mPa·s. On the other hand, when Agent B's viscosity is higher than that of Agent A, the viscosity of Agent B can be 5,000 to 70,000 mPa·s, 10,000 to 50,000 mPa·s, or 20,000 to 35,000 mPa·s. If Agent A and Agent B are viscous liquids (viscosity of 5,000 mPa·s or more), the viscosity is measured using a B-type viscometer at 25°C using a No. 4 rotor at a rotation speed of 12 rpm for a measurement time of 60 seconds.

[0063] The use of this multi-component hair treatment agent is not limited, and it can be used alone, but it can also be used in combination with various trimers. The multi-component hair treatment composition can be used as a composition containing a treatment component (treatment composition, shampoo composition, etc.). Furthermore, hair coloring compositions (oxidative hair dyes, color treatments, color shampoos, hair manicures, etc.) and hair shape-altering compositions (perms, hair straighteners, curling agents, styling agents, etc.) can be used as post-treatment agents, and the multi-component hair treatment composition can be used before these post-treatment agents. That is, it can be used as a pre-treatment agent to be used before these post-treatment agents. This can improve the effect of the post-treatment agent. Among the above, in the present invention, treatment compositions and shampoo compositions are preferred, and treatment compositions are more preferred. When using a treatment composition, only Agent A constituting the multi-component hair treatment composition may be used as the treatment composition, or only Agent B constituting the multi-component hair treatment composition may be used as the treatment composition, but it is preferable that both Agent A and Agent B are used as treatment compositions. That is, it is particularly preferable that the multi-component hair treatment composition be used as a system treatment. In this case, agent A and agent B are the components that make up the system treatment.

[0064] [2] How to use the multi-drug hair treatment product The method for using a multi-component hair treatment agent of the present invention is a method for using the multi-component hair treatment agent described above, characterized in that it comprises a step of applying agent A and a step of applying agent B, and the step of applying agent B is a step that occurs after the step of applying agent A.

[0065] The agent A application step is a step of applying agent A to hair. The agent B application step is a step of applying agent B to hair, and the agent B application step is a step that occurs after the agent A application step. The method of applying agent A and agent B is not limited to any particular method. For example, <1> each hair treatment agent can be applied to hair using a tool such as a comb, brush, or spatula. Furthermore, <2> it can be applied to hair using the user's hands. Furthermore, <3> it can be applied by spraying onto hair as a mist, aerosol, foam, or the like. Additionally, it can be applied by <4> impregnation (dipping), coating, penetration, or other procedures. These agents may be used alone or in combination of two or more. Among these, <1> and / or <2> are preferred.

[0066] Agents A and B may be applied to hair that is wet with water or warm water, or to dry hair. Agents A and B applied to the hair may be rinsed off before the next hair treatment agent is applied, or the next hair treatment agent may be applied over the hair without rinsing off the agents A and B applied to the hair. After application of agents A and B, they may or may not be rinsed off. Among these, it is preferable to apply agent B while agent A is still present after agent A is applied without rinsing it off. That is, it is preferable that the hair in the agent B application step is hair on which agent A applied in the agent A application step remains. This can more effectively improve the feel and difficulty in handling caused by hair changes. The application amounts (application amounts) of agents A and B are not limited, and agent A may be applied in greater amounts than agent B, or agent B may be applied in greater amounts than agent A. However, it is preferable that agents A and B are applied in approximately equal amounts. That is, the application amount of agent A is S A (g), and the amount of agent B applied is S B (g), the ratio (S A / S B ) is preferably set to 0.5 to 1.5, more preferably to 0.7 to 1.3, and even more preferably to 0.9 to 1.1.

[0067] Furthermore, each agent applied to the hair may be immediately washed off, but a suitable leaving time (the time for leaving the agent applied to the hair as is) can be secured to allow the ingredients to penetrate and react into the hair. The leaving time is not limited, but can be, for example, 1 minute or more, and can even be 3 minutes or more. On the other hand, a leaving time of 15 minutes or less is usually sufficient, and can be 10 minutes or less. These upper and lower limits can be appropriately combined. Therefore, for example, the leaving time can be 1 to 15 minutes, or 3 to 10 minutes.

[0068] In this method, the components A and B may be applied in any ratio, but the anionic silicone contained in the component A applied in the component A application step is T A (g), and the cationic component contained in the agent B applied in the agent B application step is T B (g), the ratio of these (T A / T B ) is not limited, but its lower limit is preferably 0.001 or more, more preferably 0.01 or more, even more preferably 0.05 or more, and even more preferably 0.1 or more. On the other hand, its upper limit is preferably 50 or less, more preferably 20 or less, even more preferably 10 or less, even more preferably 5 or less, even more preferably 3 or less, even more preferably 2 or less, and even more preferably 1 or less. These upper and lower limit values ​​can be arbitrarily combined, but are preferably 0.001 to 50, more preferably 0.01 to 20, even more preferably 0.01 to 10, even more preferably 0.05 to 5, even more preferably 0.05 to 3, even more preferably 0.05 to 2, and even more preferably 0.1 to 1. [Example]

[0069] The present invention will be described in more detail below with reference to examples. However, these examples are merely examples shown for the convenience of explanation, and the present invention is not limited to these examples in any sense.

[0070] [1] Preparation of multi-drug hair treatment agent Agents A (A1 to A9) were obtained by mixing the anionic silicone and other ingredients shown in Table 1 in the ratios shown in Table 1. Similarly, agents B (B1 to B10) were obtained by mixing the cationic and other ingredients shown in Table 2 in the ratios shown in Table 2. The resulting agents A1 to A9 had a cream-like texture with a viscosity (measured at 25°C, 12 rpm, and 60 seconds using a Brookfield viscometer with a No. 4 rotor) of 5,000 to 25,000 mPa·s. On the other hand, the resulting agents B1 to B10 had a cream-like texture with a viscosity (measured at 25°C, 12 rpm, and 60 seconds using a Brookfield viscometer with a No. 4 rotor) of 20,000 to 35,000 mPa·s. The resulting Agents A and B were combined to obtain multi-component hair treatments as shown in Examples 1 to 16 and Comparative Examples 1 to 5 in Table 3. Note that each of the multi-component hair treatments in Example 1 and Examples 13 to 15 contains a combination of Agent A1 and Agent B1, and are the same multi-component hair treatments, but are examples in which the methods of use are different.

[0071] [2] Use of multi-ingredient hair treatment products From each of the multi-component hair treatment agents shown in Table 3, 1.5 g of Agent A and 1.5 g of Agent B were weighed out and applied to 1 g of a 10 cm long black hair bundle sample for evaluation (hair with unevenness and / or distortion at the root (unevenness and / or distortion in newly grown hair not due to external factors) selected from Chinese hair (Beaulux Co., Ltd.), and the selected hair was bleached three times using a Promaster LT (Hoyu Co., Ltd.)). The application method is as shown in Table 3. Specifically, "Agent A → Agent B, multiple applications" means that after applying Agent A, Agent A was not rinsed off, and Agent B was applied multiple times to the hair bundle sample containing Agent A. Furthermore, "Agent A → rinse → Agent B" means that after applying Agent A, Agent A was rinsed off, and then Agent B was applied to the hair bundle sample not containing Agent A. "Apply after mixing agent A and agent B" means that agent A and agent B were mixed and then the mixture was applied. "Agent B → Agent A over-applied" means that after agent B was applied, agent A was applied over the hair bundle sample containing agent B without rinsing it off. After each application, the hair bundle was left to stand for 10 minutes at room temperature of 25°C, then rinsed with warm water at 40°C to wash off all of the hair treatment agent, and then each hair bundle sample was evenly dried with warm air using a hair dryer for 10 minutes to obtain each hair bundle sample in its finished state. Each obtained hair bundle sample was evaluated for "feel" and "manageability."

[0072] [3] Evaluation of multi-drug hair treatment products (1) Evaluation of texture Each evaluation was carried out by five expert panelists, who selected the score that best suited their perception of the "feel" when they touched each hair bundle sample in the finished state obtained in [2] above with their fingers, in accordance with the following evaluation criteria (1), and calculated the arithmetic mean of the scores selected by each of the five panelists. The results are shown in Table 3.

[0073] Evaluation Criteria (1) 5: No unevenness or distortion is felt at all 4: Almost no unevenness or distortion 3: I don't feel any unevenness or distortion. 2: I feel some unevenness or distortion 1: I feel unevenness or distortion

[0074] (2) Evaluation of coherence Each evaluation was carried out by five expert panelists, who visually inspected each hair bundle sample in the finished state obtained in [2] above and touched it with their fingers to determine the "manageability" of the hair bundle. Each panelist selected the score that best matched their perception of the "manageability" of the hair bundle sample in the finished state obtained in [2] above, based on the following evaluation criteria (2). The arithmetic mean of the scores selected by each of the five panelists was calculated. The results are shown in Table 3.

[0075] Evaluation Criteria (2) 5: Very well organized 4: Excellent cohesion 3: Good cohesion 2: Somewhat disorganized 1: No cohesion at all

[0078] [Table 3]

[0079] [3] Effects of the embodiment In Comparative Example 1, which used a combination of Agent A3, an Agent A that does not contain anionic silicone, and Agent B1, an Agent B that contains a cationic component, the manageability rating was 4, but the feel rating was only 2. In Comparative Example 2, which used a combination of Agent A4, an Agent A that does not contain anionic silicone, and Agent B1, an Agent B that contains a cationic component, the manageability rating was 3, but the feel rating was only 2. In Comparative Example 3, which used a combination of Agent A1, an Agent A that contains anionic silicone, and Agent B4, an Agent B that does not contain a cationic component, the feel rating was 3, but the manageability rating was only 2. In Comparative Example 4, which used a combination of Agent A1, an Agent A that contains anionic silicone, and Agent B5, an Agent B that does not contain a cationic component, the manageability rating was 3, but the feel rating was only 2. Furthermore, in Comparative Example 5, which used a combination of Agent A1, which is Agent A containing anionic silicone, and Agent B6, which is Agent B containing no cationic component, the evaluation of feel was only 1, and the evaluation of hold was also only 2.

[0080] In contrast, in Examples 1 to 16, which used a combination of agents A1 to A2 and A5 to A9, which are agent A containing an anionic silicone, and agents B1 to B3 and B7 to B10, which are agent B containing a cationic component, the feel was rated 3 to 5, and the manageability was also rated 3 to 5, which were excellent results. This shows that the multi-component hair treatment composition of the present invention can improve the feel and difficulty in management caused by changes in hair. Furthermore, when Example 1 and Example 14, which combined Agent A and Agent B, respectively, it can be seen that Example 1, in which Agent A was applied first, and then Agent B, had better evaluations of feel and manageability than Example 14, in which a mixture of Agents A and B was applied. This shows that the effects of the multi-agent hair treatment composition can be obtained more effectively by mixing Agents A and B on the hair rather than by mixing them before application to the hair.
