At this time, in the first agent, there are at least two kinds selected from the silicone group consisting of (A) cyclic silicone, (B) amino-modified silicone, (C) highly polymerized methylpolysiloxane, and (D) highly polymerized amino-modified silicone. Contained. It is considered that a plurality of types of silicones act on the finished hair in a well-balanced manner by selecting and combining silicones from the silicone group composed of these specific silicones. Therefore, a smooth feeling can be sufficiently imparted to the finished hair without causing problems such as stickiness of the hair.
[0055]
According to the first embodiment described in detail above, the following effects are exhibited.
In the hair cosmetic composition of the first embodiment, the first agent contains (A) a cyclic silicone, (B) an amino-modified silicone, (C) a highly polymerized methylpolysiloxane, and (D) a highly polymerized amino-modified silicone. At least two selected from the silicone group consisting of: Accordingly, it is considered that a plurality of types of silicone act on the finished hair in a well-balanced manner, and a smooth feeling can be sufficiently imparted to the finished hair. In addition, at least two kinds selected from the silicone group can uniformly attach components such as an alkaline agent and a dye to the hair, and improve the leveling and lightness of the finished hair.
[0056]
In the hair cosmetic composition of the first embodiment, the silicone group is composed of (A) cyclic silicone, (B) amino-modified silicone, and (C) highly polymerized methylpolysiloxane. Therefore, a smooth feeling, moist feeling and smooth feeling can be sufficiently imparted to the finished hair.
[0057]
In the hair cosmetic composition of the first embodiment, the silicone group is composed of (A) a cyclic silicone and (D) a highly polymerized amino-modified silicone. Therefore, a smooth feeling, moist feeling and smooth feeling can be sufficiently imparted to the finished hair.
[0058]
In the hair cosmetic composition according to the first embodiment, the first agent contains at least one selected from (E) an amphoteric polymer compound and (F) a cationic polymer compound. Therefore, the feeling at the time of plain rinsing can be made sufficiently smooth.
[0059]
-Conventionally, in a hair cosmetic composition containing at least one selected from ammonia and alkanolamine in the first agent, there is a problem that the feel of the hair may be deteriorated, such as the hair after finishing is dry. . In the hair cosmetic composition of the first embodiment, since the first agent contains at least two selected from the silicone group, the first agent contains at least one selected from ammonia and alkanolamine. Even in this case, the feel of the finished hair can be improved.
(Second Embodiment)
Hereinafter, a second embodiment in which the hair cosmetic composition of the present invention is applied to a hair bleaching agent will be described focusing on differences from the first embodiment.
[0060]
The hair cosmetic composition of the second embodiment is mixed with the second agent as a composition containing an oxidizing agent as the first agent of the hair bleaching agent, and used for hair decolorization. The user finishes the hair bleaching process by applying a plain rinse to the hair after applying the mixture of the first agent and the second agent to the hair.
<First Agent>
The 1st agent in this embodiment uses what remove | excluded dyes, such as an oxidation dye intermediate body, from the 1st agent in the said 1st Embodiment.
<Second agent>
As the second agent in the present embodiment, the same agent as the second agent in the first embodiment is used.
[0061]
According to the hair bleaching agent in the second embodiment, a smooth feeling can be sufficiently imparted to the finished hair.
[0062]
【Example】
  Next, the embodiment will be described more specifically with reference to examples and comparative examples.
(Example1,5-7, reference examples2 to4 and Comparative Examples 1 to 4)
  The 1st agent and 2nd agent of the hair dye shown in Table 1 were prepared. Subsequently, the first agent and the second agent were mixed and applied to healthy hair of women in their 20s, and then the hair dyeing treatment was finished by applying plain rinse to the hair left for a certain period of time. The first agent and the second agent are mixed at a weight ratio of 1: 2. Moreover, the numerical value in Table 1 shows weight%.
[0063]
[Table 1]

  A specialized panelist performed sensory evaluation on the feel of the finished hair according to the following evaluation criteria (1) to (4). Similarly, sensory evaluation was performed according to the following evaluation criteria (5) for the feel of the hair during plain rinse. Moreover, sensory evaluation was performed according to the evaluation criteria of following (6) about the leveling property of the hair after finishing. These evaluation results are shown in Table 2.
[0064]
(1) Smooth feeling after finishing
The evaluation was made in 4 grades: excellent smooth feeling (◎), smooth feeling good (◯), smooth feeling slightly deficient (△), and smooth feeling deficient (x).
[0065]
(2) Smooth feeling after finishing
The evaluation was made in four stages, with a smooth feeling (◎), a smooth feeling (good), a slightly dull feeling (△) and a dull feeling (x).
[0066]
(3) Smooth feeling after finishing
The evaluation was made in 4 grades: excellent smooth feeling (◎), good smooth feeling (◯), slightly smooth feeling (△) and poor smooth feeling (x).
[0067]
(4) Moist feeling after finishing
The evaluation was made on a four-point scale: excellent moist feeling (◎), moist feeling good (◯), moist feeling slightly deficient (△), and moist feeling deficient (x).
[0068]
(5) Smooth feeling during plain rinse
The evaluation was made in 4 grades: excellent smooth feeling (◎), smooth feeling good (◯), smooth feeling slightly deficient (△), and smooth feeling deficient (x).
[0069]
(6) Leveling of hair after finishing
The evaluation was made in four stages, where the entire hair was uniformly dyed (◎), almost uniform (○), slightly non-uniform (Δ), and fairly non-uniform (x).
[0070]
[Table 2]

  As is clear from the results in Table 2, in each Example, the smooth feeling after finishing was excellent or good. Example 1, 6In the first agent of Example 7, the component (A), the component (B) and the component (C) selected from the silicone groupMinutesSince it was contained, the results were excellent in terms of smoothness after finishing, smoothness, smoothness and moistness. Further examples1In addition, the (E) component is contained in the first agent of Example 5 and the (F) component is contained in the first agent of Example 7, so that the smooth feeling during plain rinse is excellent. became. In addition, each component selected from the silicone group has an effect of uniformly adhering alkanolamines, dyes, and the like to the hair, so that good leveling of the finished hair was obtained.
[0071]
On the other hand, since the silicone contained in the 1st agent of Comparative Examples 1-4 is a kind chosen from a silicone group, smooth feeling is not fully given to finished hair.
[0072]
In addition, the said embodiment can also be changed and comprised as follows.
In the first embodiment, the hair cosmetic composition is applied to the first agent of the hair dye, and in the second embodiment, the first agent of the hair bleaching agent. In addition to these, it is also possible to apply to hair care agents such as decoloring agents, permanent wave agents, shampoos, rinses, treatments, and styling agents. In this case, if a component necessary for various uses is blended with at least two types of hair cosmetic compositions selected from the silicone group consisting of the components (A), (B), (C) and (D). Good.
