Description

[Technical Field]

[0001] The present invention relates to a multi-component hair treatment agent and a hair treatment method using the multi-component hair treatment agent. [Background technology]

[0002] Hair treatment products are selected according to each consumer's needs and preferences, and various types are available to suit different uses and purposes. Examples of hair treatment products include single-component hair treatment products and multi-component hair treatment products containing multiple components.

[0003] Multi-component hair treatments are sometimes used to enhance the desired effect compared to single-component hair treatments, or to prolong the effect, by using multiple components. Furthermore, because multi-component hair treatments use multiple components, the application time tends to be longer and more time-consuming than with single-component hair treatments. However, this extra effort has the advantage of increasing the satisfaction of the subject with the treatment.

[0004] As an example of a multi-component hair treatment agent, Japanese Patent Publication No. 2008-137995 (Patent Document 1) proposes a technology to provide a hair cosmetic that can uniformly impart excellent smoothness to the hair from root to tip by comprising a hair cosmetic containing a predetermined amount of a quaternary ammonium salt type cationic surfactant, an amino-modified silicone, a dialkyl ether, and water, and a predetermined amount of a hair cosmetic containing a predetermined amount of acids, a polyhydric alcohol, and water.

[0005] [Patent Document 1] Japanese Patent Publication No. 2008-137995 [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] The components of multi-component hair treatments contain various ingredients depending on the desired effect, but as shown in Patent Document 1, some contain amino-modified silicone. Amino-modified silicone has high adsorption properties to hair and can exhibit good conditioning effects. Therefore, attempts have been made to impart further conditioning effects to hair by combining components containing amino-modified silicone with other components in multi-component hair treatments.

[0007] However, in multi-component hair treatments containing amino-modified silicones, the amino-modified silicones sometimes adsorbed excessively onto the hair, resulting in a sticky feeling after treatment. This stickiness tended to occur more frequently with higher concentrations of amino-modified silicones. Furthermore, this tendency was more pronounced when multi-component hair treatments containing amino-modified silicones were used on hair damaged by chemical treatments such as bleaching or perming.

[0008] In view of the above circumstances, the present invention aims to suppress the stickiness of the finished hair in a multi-component hair treatment agent containing a component containing amino-modified silicone. [Means for solving the problem]

[0009] As a result of diligent research, the inventors have newly discovered that a multi-component hair treatment agent that suppresses stickiness of the finished hair can be realized by combining agent A, which contains one or more selected from polyether-modified silicone and polyglycerin-modified silicone, as well as a higher alcohol, and agent B, which contains amino-modified silicone. Based on the above discovery, the inventors completed the present invention.

[0010] The present invention includes the following inventions [1] to [7].

[0011] The multi-agent hair treatment agent of [1] contains one or more selected from polyether-modified silicone and polyglycerol-modified silicone, and Agent A containing a higher alcohol, and Agent B containing an amino-modified silicone, and is a multi-agent hair treatment agent.

[0012] The multi-agent hair treatment agent of [2] is the multi-agent hair treatment agent of [1], and as the higher alcohol formulated in Agent A, it is formulated with a higher alcohol that is liquid at 25°C.

[0013] The multi-agent hair treatment agent of [3] is the multi-agent hair treatment agent of [2], and as the liquid higher alcohol, it is formulated with an unsaturated higher alcohol that is liquid at 25°C.

[0014] The multi-agent hair treatment agent of [4] is any one selected from the multi-agent hair treatment agents of [1] to [3], and as one or more selected from the polyether-modified silicone and polyglycerol-modified silicone formulated in Agent A, at least a polyether-modified silicone is formulated.

[0015] The multi-agent hair treatment agent of [5] is any one selected from the multi-agent hair treatment agents of [1] to [4], and the blending amount of the amino-modified silicone blended in Agent B is 0.5% by mass or more.

[0016] The multi-agent hair treatment agent of [6] is any one selected from the multi-agent hair treatment agents of [1] to [5], and Agent B is used after using Agent A.

[0017] The hair treatment method of [7] is a hair treatment method using any one selected from the multi-agent hair treatment agents of [1] to [6].

Examples of silicones other than amino-modified silicones include dimethyl silicone, phenyl-modified silicone, silanol group-containing silicone, long-chain alkyl-modified silicone, and three-dimensional crosslinked silicones.

[0092] In the case of Agent B of this embodiment, if a silicone other than amino-modified silicone is included, the amount of the other silicone is not particularly limited and may be set as appropriate. If Agent B of this embodiment is in the form of a cream, the amount of the other silicone may be, for example, 0.1% by mass or more and 15% by mass or less, and if Agent B of this embodiment is in the form of a non-aqueous composition described later, the amount may be, for example, 30% by mass or more and 95% by mass or less.

[0093] (Dosage form of drug B) There are no particular restrictions on the dosage form of Agent B in this embodiment, and it can be in various forms such as liquid (including emulsion), cream, gel, paste, spray, or foam. Agent B in this embodiment may be liquid in the sense that it is easy to apply uniformly to the hair, or it may be a cream or gel in the sense that it is easy to apply. Agent B in this embodiment may also be a cream in the sense that it contains a cationic surfactant, a higher alcohol, and water.

[0094] Agent B in this embodiment may be, for example, an emulsifying composition. Examples of emulsifying compositions include oil-in-water emulsions, water-in-oil emulsions, and water-in-oil emulsions.

The viscosity of agent B is not particularly limited, but for example, it is 100,000 mPa·s or less. The viscosity of agent B can be measured using a measurement method with a type B viscometer, similar to the viscosity of agent A described above.

[0097] (pH of agent B) The pH of agent B in this embodiment may be set appropriately depending on the dosage form of agent B. The pH of agent B is not particularly limited, but for example, it is between 3 and 9. The above pH values ​​refer to the measured values ​​obtained at 25°C using a known pH meter.

[0098] (Manufacturing method for agent B) Agent B of this embodiment may be manufactured using a known method for manufacturing hair treatment agents, depending on the dosage form and other components.

[0099] (How to use) The method of using the multi-component hair treatment agent of this embodiment can adopt known methods of use for multi-component hair treatment agents. For example, it can be used by applying appropriate amounts of agent A and agent B to the hair by means of application.

[0100] The multi-component hair treatment agent of this embodiment does not have any particular order of use between agent A and agent B. Therefore, it may be a multi-component hair treatment agent in which agent B is used after agent A, or a multi-component hair treatment agent in which agent A is used after agent B. In terms of usage, both agent A and agent B may be rinsed off after use, neither agent A nor agent B may be rinsed off after use, or one of agent A or agent B may be not rinsed off after use and the other may be rinsed off after use. From the viewpoint of further suppressing stickiness of the finished hair, it is preferable to use one of agent A or agent B and not rinse it off after use, or to rinse off both agent A and agent B after use.

[0101] If the multi-component hair treatment agent of this embodiment is a multi-component hair treatment agent of three or more components, including one or more other agents in addition to agents A and B, the order in which each component (agent A, agent B, and one or more other agents) is used is not particularly limited. Examples of usage include (a) to (b) below. (a) When using agent B after using agent A, the method of using one or more other agents before or after using agent B. (i) When using agent A after using agent B, an action in which one or more other agents are used before or after using agent A.

[0102] Furthermore, after using each component in the usage methods described in (a) and (b) above, rinsing may or may not be performed. From the viewpoint of further suppressing the stickiness of the finished hair, it is preferable to rinse off the component used last in a multi-component hair treatment agent.

[0103] (Application) The use of the multi-component hair treatment agent of this embodiment is not particularly limited, as long as it is used on hair. Examples of multi-component hair treatment agents used on hair and / or scalp include multi-component hair care products and multi-component styling products.

[0104] The multi-component hair care products described above are used for hair care and treatment. These multi-component hair care products may include multi-component hair treatments, or multi-component hair care products for pre-treatment or post-treatment of perms, coloring, or bleaching.

[0105] Examples of multi-component hair care products include combinations of one or more types of hair treatments (including rinse-off hair treatments, hair conditioners, hair packs, hair masks, and styling treatments) and leave-in hair treatments (including styling leave-on treatments) where agent A and agent B are selected from the group (if other agents besides agent A and agent B are included, the other agents are arbitrarily selected from the above group). Examples of agent A and agent B in a multi-component hair care product include the following combinations. Both Agent A and Agent B are rinse-off hair treatments. • Agent A is a rinse-off hair treatment, and Agent B is a leave-in hair treatment. • Agent A is a leave-in hair treatment, and Agent B is a rinse-off hair treatment. Both Agent A and Agent B are leave-in hair treatments.

[0106] The multi-component styling products described above are used to temporarily hold a hairstyle in place. Examples of multi-component styling products include one or more combinations of agent A and agent B selected from the following formulations: hair spray, hair mist, mousse, foam, hair gel, setting lotion, hair cream, and hair wax (if other agents are included besides agent A and agent B, these other agents can be arbitrarily selected from the above formulations).

[0107] (Target hair) The hair to which the multi-component hair treatment agent of this embodiment can be used is not particularly limited and may include hair with a history of chemical treatment (e.g., perming, coloring, or bleaching) and hair without such a history. The multi-component hair treatment agent of this embodiment contains agent B, which is formulated with amino-modified silicone, and can suppress stickiness of the finished hair even when used on hair damaged by chemical treatments such as bleaching.

[0108] <Hair Treatment Methods> The hair treatment method of this embodiment is a method of treating hair using the multi-component hair treatment agent of this embodiment. The hair treatment method of this embodiment may be used for cosmetic purposes.

[0109] As for the hair treatment method of this embodiment, in addition to using the multi-component hair treatment agent of this embodiment, any known method of using a multi-component hair treatment agent may be adopted. For example, the method of using the multi-component hair treatment agent of this embodiment described above may be used. [Examples]

[0115] <1> Evaluation of multi-component hair treatment agents of Examples 1a, 1b, 2-10, and Comparative Examples 1-5

[0116] (evaluation) Using the A and B agents prepared in Examples 1a, 1b, 2-10, and Comparative Examples 1-5 described above, the following hair treatments and evaluations were performed.

[0117] Black hair samples taken from the same Japanese woman were bleached by immersing them for 2 hours in an aqueous solution of 6% by mass of hydrogen peroxide and 25% ammonia water adjusted to pH 11. After bleaching, the hair was rinsed with running water and dried with a hairdryer. Using the bleached and dried hair, multiple hair bundles (each bundle consisting of human hair approximately 25 cm long, weighing approximately 5 g) were created. The created hair bundles were rinsed with water, washed with shampoo (Milbon's "Grand Linkage Willow Luxe Shampoo"), and then rinsed with water. Next, 0.5 g of agent A from each of the multi-component hair treatment agents in Examples 1a, Examples 2-10, and Comparative Examples 1-5, or agent B from the multi-component hair treatment agent in Example 1b, was taken by hand and applied to each hair bundle. Next, 0.5g of each component B from the multi-component hair treatment agents of Example 1a, Examples 2-10, and Comparative Examples 1-5, or component A from the multi-component hair treatment agent of Example 1b, was taken into the hand and applied to each strand of hair that had not been rinsed after applying component A or B. The hair was massaged in for about 10 seconds, and then rinsed with water. The "smoothness during rinsing" was evaluated during this rinsing. The hair strands that had been rinsed with water were then dried with a hairdryer to finish, and the "manageability of the finished hair" and the "suppression of stickiness in the finished hair" (hereinafter referred to as "suppression of stickiness in the finished hair") were evaluated. The evaluation was carried out by five evaluators who routinely evaluate hair treatment agents.

[0118] Furthermore, for each of the evaluation items above, "smoothness during rinsing," "manageability of hair after finishing," and "suppression of stickiness after finishing," each evaluator scored the hair bundles using the multi-component hair treatment agent of Comparative Example 3 as a baseline (3 points), and then scored them according to the following evaluation criteria. Then, the average score given by all evaluators was calculated for each evaluation item.

[0119] (Evaluation criterion: Smoothness during rinsing) 5 points: Significantly superior to the standard in terms of smoothness during rinsing (compared to the standard, the hair glides much more smoothly when you run your fingers through it during rinsing). 4 points: Slightly better than the standard in terms of smoothness during rinsing (compared to the standard, the hair feels slightly smoother when you run your fingers through it during rinsing). 3 points: Smoothness during rinsing is about the same as the standard (when running your fingers through your hair during rinsing, the hair glides about the same as the standard). Points 2: Slightly inferior to the standard in terms of smoothness during rinsing (compared to the standard, the hair doesn't glide as smoothly when you run your fingers through it during rinsing). 1 point: The smoothness during rinsing is significantly inferior to the standard (compared to the standard, the hair does not glide smoothly when you run your fingers through it during rinsing).

[0120] (Evaluation criteria: How well the hair stays together after styling) 5 points: The finished hair is much more manageable than the standard (compared to the standard, the finished hair is much more manageable from the mid-lengths to the ends). 4 points: Slightly better than the standard in terms of hair manageability after application (compared to the standard, the finished hair is slightly more manageable from the mid-lengths to the ends). 3 points: The finished hair has a level of manageability that is comparable to the standard (in the finished hair, the manageability from the middle to the ends of the hair is comparable to the standard). Points 2: The finished hair is slightly less manageable than the standard (compared to the standard, the finished hair is slightly more spread out from the middle to the ends). 1 point: The finished hair is significantly inferior to the standard in terms of manageability (compared to the standard, the finished hair is very spread out from the middle to the ends).

[0121] (Evaluation criteria: Suppression of stickiness in the finished product) 5 points: The degree of stickiness after application is much less than the standard (compared to the standard, the finished hair feels almost completely free of stickiness when touched). 4 points: The degree of stickiness after application is slightly less than the standard (compared to the standard, the finished hair doesn't feel as sticky to the touch). 3 points: The stickiness of the finished product is about the same as the standard (the sticky feeling when touching the finished hair with your hand is about the same as the standard). 2 points: The degree of stickiness in the finished product is slightly greater than the standard (compared to the standard, the finished hair feels slightly stickier to the touch). 1 point: The degree of stickiness in the finished product is much greater than the standard (compared to the standard, the finished hair feels very sticky to the touch).

[0122] (Evaluation results) The evaluation results for Examples 1a, 1b, Examples 2-10, and Comparative Examples 1-5 are shown in Tables 1-5 below. In Tables 1-5, in the "Order of Use" column, "Agent A → Agent B" means that Agent A was used on the hair bundle in that order, and "Agent B → Agent A" means that Agent B was used on the hair bundle in that order.

[0123] (Evaluation results for Example 1a, Examples 2-4, and Comparative Examples 1-3) Tables 1 and 2 below show the evaluation results for the multi-component hair treatment agents of Example 1a, Examples 2-4, and Comparative Examples 1-3.

[0124] [Table 1]

[0125] [Table 2]

[0126] As shown in Tables 1 and 2, the hair bundles treated with the multi-component hair treatment agents of Example 1a and Examples 2-4 showed less stickiness in the finished hair compared to the hair bundles treated with the multi-component hair treatment agents of Comparative Examples 1-3. Here, the multi-component hair treatment agents of Example 1a and Examples 2-4 contain polyether-modified silicone and higher alcohols in agent A, while the multi-component hair treatment agents of Comparative Examples 1-3 either do not contain polyether-modified silicone and higher alcohols in agent A, or do not contain higher alcohols at all. Note that the multi-component hair treatment agents of Example 1a, Examples 2-4, and Comparative Examples 1-3 all share agent B (containing amino-modified silicone). Therefore, it can be seen that a multi-component hair treatment agent combining agent A, which contains polyether-modified silicone and higher alcohols, and agent B, which contains amino-modified silicone, can suppress the stickiness of the finished hair in a multi-component hair treatment agent containing an amino-modified silicone component.

[0127] Furthermore, as shown in Tables 1 and 2, the multi-component hair treatment agents of Examples 1a and 2-3, in which liquid higher alcohol was incorporated into agent A, were superior in smoothness during rinsing and manageability of the hair after finishing compared to the multi-component hair treatment agent of Example 4, in which solid higher alcohol was incorporated into agent A. Therefore, it can be seen that using liquid higher alcohol as the higher alcohol incorporated into agent A suppresses the stickiness of the finish caused by amino-modified silicone while also providing superior smoothness during rinsing and manageability of the hair after finishing.

[0128] (Evaluation results for Example 1a, Examples 5-8, and Comparative Examples 3-5) Tables 3 and 4 below show the evaluation results for the multi-component hair treatment agents of Example 1a, Examples 5-8, and Comparative Examples 3-5.

[0129] [Table 3]

[0130] [Table 4]

[0131] As shown in Tables 3 and 4, the hair bundles treated with the multi-component hair treatment agents of Example 1a and Examples 5-8 showed less stickiness in the finished product compared to the hair bundles treated with the multi-component hair treatment agents of Comparative Examples 3-5. Here, the multi-component hair treatment agents of Example 1a and Examples 5-8 contain a polyether-modified silicone or polyglycerin-modified silicone and a higher alcohol in agent A, while the multi-component hair treatment agents of Comparative Examples 5-8 either do not contain a polyether-modified silicone or polyglycerin-modified silicone and a higher alcohol in agent A, or do not contain a higher alcohol at all. Note that the multi-component hair treatment agents of Example 1a, Examples 5-8, and Comparative Examples 3-5 all share agent B (containing amino-modified silicone). Therefore, it can be seen that a multi-component hair treatment agent, which combines agent A, which contains polyether-modified silicone or polyglycerin-modified silicone and a higher alcohol, with agent B, which contains amino-modified silicone, can suppress the stickiness of the finished hair in a multi-component hair treatment agent containing amino-modified silicone.

[0132] Furthermore, as shown in Tables 3 and 4, the multi-component hair treatment agents of Examples 1a and 5-7, in which polyether-modified silicone was incorporated into agent A, exhibited superior smoothness during rinsing compared to the multi-component hair treatment agent of Example 8, in which polyglycerin-modified silicone was incorporated into agent A. Therefore, it can be seen that using polyether-modified silicone as the polyether-modified silicone or polyglycerin-modified silicone incorporated into agent A suppresses the stickiness of the finish caused by amino-modified silicone while also providing superior smoothness during rinsing.

[0133] (Evaluation results for Example 1a, Example 1b, Examples 9-10, and Comparative Example 3) Table 5 below shows the evaluation results for the multi-component hair treatment agents of Example 1a, Example 1b, Examples 9-10, and Comparative Example 3.

[0134] [Table 5]

[0135] As shown in Table 5, the hair bundles treated with the multi-component hair treatment agents of Examples 1a, 1b, and 9-10 showed less stickiness in the finished result compared to the hair bundles treated with the multi-component hair treatment agent of Comparative Example 3. Here, the multi-component hair treatment agents of Examples 1a, 1b, and 9-10 contain a polyether-modified silicone or polyglycerin-modified silicone and a higher alcohol in agent A, while the multi-component hair treatment agent of Comparative Example 3 does not contain a polyether-modified silicone or polyglycerin-modified silicone and a higher alcohol in agent A. Note that the multi-component hair treatment agents of Examples 1a, 1b, and Comparative Example 3 all share agent B (containing amino-modified silicone), and the multi-component hair treatment agents of Examples 9-10 use agent B containing amino-modified silicone, but their composition differs from that of agent B in Examples 1a, 1b, and Comparative Example 3. Therefore, it can be seen that a multi-component hair treatment agent, which combines agent A, which contains polyether-modified silicone or polyglycerin-modified silicone and a higher alcohol, with agent B, which contains amino-modified silicone, can suppress the stickiness of the finished hair in a multi-component hair treatment agent containing amino-modified silicone.

[0136] Furthermore, as shown in Table 5, the multi-component hair treatment agent of Example 1a, in which agent A and then agent B were used on the hair bundles, was able to suppress the stickiness of the finished product more effectively than the multi-component hair treatment agent of Example 1b, in which agent B and then agent A were used on the hair bundles. Therefore, in a multi-component hair treatment agent that combines agent A, which is formulated with polyether-modified silicone or polyglycerin-modified silicone and a higher alcohol, and agent B, which is formulated with amino-modified silicone, it can be seen that using agent B after agent A can further suppress the stickiness of the finished product in a multi-component hair treatment agent containing an amino-modified silicone component.

[0137] <2> Evaluation of the multi-component hair treatment agents of Example 11 and Comparative Example 6

[0138] (evaluation) Using the respective A agents and B agents from Example 11 and Comparative Example 6 prepared above, hair treatment and evaluation were performed in the same manner as described in "<1> Evaluation of multi-component hair treatment agents of Example 1a, Example 1b, Examples 2-10, and Comparative Examples 1-5" above.

[0139] For each evaluation item, "smoothness during rinsing," "hair manageability after finishing," and "stickiness after finishing," each evaluator used the evaluation of the hair bundle when using the multi-component hair treatment agent of Comparative Example 6 as the baseline (3 points). Then, points were assigned to each evaluation item based on the same evaluation criteria as above, and the average of the scores given by all evaluators was calculated.

[0140] (Evaluation results) The evaluation results for Example 11 and Comparative Example 6 are shown in Table 6 below. In the "Order of Use" column in Table 6, "Agent A → Agent B" means that Agent A was used on the hair bundle in that order, followed by Agent B.

[0141] [Table 6]

[0142] As shown in Table 6, the hair bundles treated with the multi-component hair treatment agent of Example 11 showed less stickiness in the finished hair compared to the hair bundles treated with the multi-component hair treatment agent of Comparative Example 6. Here, the multi-component hair treatment agent of Example 11 contains polyether-modified silicone and higher alcohols in component A, while the multi-component hair treatment agent of Comparative Example 6 does not contain polyether-modified silicone in component A. Note that both the multi-component hair treatment agents of Example 11 and Comparative Example 6 share component B (containing amino-modified silicone). Therefore, it can be seen that a multi-component hair treatment agent combining component A, which contains polyether-modified silicone and higher alcohols, and component B, which contains amino-modified silicone, can suppress the stickiness of the finished hair in a multi-component hair treatment agent containing amino-modified silicone.
