Description

  The present invention relates to a hair dyeing / decoloring composition.

  Conventionally, the color of hair has been adjusted by dyeing or decoloring the hair. For this, hair dyes and hair bleaching agents are used.

  The hair dye contains an oxidative dye and an oxidant. This oxidant decomposes the melanin pigment in the hair and decolorizes the hair. Also, the oxidant dye is oxidized and colored by this oxidant, and the colored oxidative dye penetrates into the hair, thereby dyeing the hair. Has been done. Further, the hair bleaching agent contains an oxidizing agent. This oxidant decomposes the melanin pigment in the hair and decolorizes the hair.

  These hair dyes and hair bleaching agents may contain an alkali agent. Alkaline agents promote the discoloration of oxidants to promote hair decolorization and oxidative dye color development, and swell cuticles that exist on the surface of the hair to facilitate the penetration of dyes and oxidants into the hair. It is used for the purpose of.

  As the alkaline agent, carbonates, silicates, and the like are sometimes used for the purpose of low bromide. For example, Patent Documents 1 to 3 disclose hair dyes using carbonates. Further, for example, Patent Document 4 discloses a hair dye using metasilicate.

JP 2006-151868 A JP 2003-40747 A JP 2004-161707 A JP 2009-209113 A

  Here, when metasilicate is used as an alkaline agent, when the metasilicate stored in powder form before use is dissolved in a solvent such as water, heat is generated locally, and the heated portion strongly Color may develop and uneven brightness may occur. On the other hand, when carbonate is used as an alkaline agent, even if it is stored in a powder form before use, since heat of dissolution hardly occurs when dissolved in a solvent such as water, uneven brightness due to this is unlikely to occur. . Therefore, from this viewpoint, it is preferable to use carbonate as the alkali agent.

  When carbonate is used as an alkaline agent, no itchiness, hair entanglement, or wrinkle after finishing, as seen when using metasilicates, has been observed. In terms, the feel of the hair was a good evaluation. However, although the finished hair has flexibility, it has been found that the hair feels rough, and this makes it difficult to pass through the finger (slip feeling when passing through the hand). This was also found to be a unique feel when carbonate was used.

  The problem to be solved by the present invention is to provide a hair dyeing and decoloring composition that suppresses a peculiar rough feeling when carbonate is used and is excellent in the feel of the hair after finishing.

In order to solve the above-mentioned problems, a hair dyeing / decoloring composition according to the present invention is a hair dyeing / decoloring composition comprising the following components (A) to (C): The gist is that the blending amount is in the range of 1 to 5% by mass, and the mass ratio of the component (A) to the component (B) is in the range of 0.02 to 6.5. is there.

Excellent.

  At this time, when the component (D) is further contained, a peculiar rough feeling when the carbonate is used can be further suppressed, and the feel of the hair after finishing is excellent. And when it is foamy, when a carbonate is used, a peculiar rough feeling can be eliminated and suppressed.

When the first agent is powdery and the second agent is liquid, the component (A) in the first agent is mixed with the liquid of the second agent in the powder state, but the component (A) is Since it is a carbonate, heat of dissolution hardly occurs during mixing. Therefore, the coloring composition can suppress uneven coloring due to local heat generation as compared to metasilicate or the like that generates heat of dissolution. In addition, when metasilicate is blended, it is difficult to store in an aqueous solution, and even if stored in powder form, it may absorb moisture and the storage stability of the system may be poor. It ’s hard to make it worse.

Subsequently, the obtained 1st agent and 2nd agent were mixed by the mixing ratio (mass ratio) of Table 1, Table 2, and the composition for hair dyeing was prepared. In the case where the final dosage form is described as “foam”, the first agent and the second agent were placed in a closed container and shaken to make the hair dyeing composition foam. On the other hand, in the case where the final dosage form is described as “cream”, the first agent and the second agent were put in an open container and gently mixed without foaming in the container. In addition, the unit of the compounding quantity of each component of Table 1 and Table 2 is the mass%.

(Dyeing process)
Each prepared hair dyeing composition was applied to a black human hair bundle (hereinafter simply referred to as “hair bundle”) with a hand wearing thin resin gloves, and then the hair bundle was placed in a thermostatic chamber ( (30 ° C.) for 30 minutes. Then, the hair bundle was washed with tap water, and then the hair bundle was treated once with shampoo and rinse (conditioner). The hair bundle was then dried. Then, it was left at room temperature for one day. The hair bundle was dyed as described above.

(About the feeling after finishing (slip feeling))
Compared the feeling when the finger was passed through the hair bundle after the dyeing treatment and the feel when the finger was passed through the hair bundle that was not dyed, the hair bundle did not feel rough and the hand was passed through From the viewpoint of whether or not the feeling of slipping is good, the feel of the hair bundle after the dyeing treatment was evaluated. The evaluation criteria are as follows. The evaluation results are shown in Tables 1 and 2.
Evaluation 5: The feeling of slip was very good.
Evaluation 4: The slip feeling was good.
Evaluation 3: The slip feeling was relatively good.
Evaluation 2: The feeling of slipping was slightly bad.
Evaluation 1: The feeling of slip was very bad.

(Feel after finishing (itch, entanglement, wrinkle))
Compare the feel when the finger is passed through the hair bundle after dyeing and the feel when the finger is passed through the hair bundle that is not dyed. From the viewpoint of whether or not it is difficult to pass, the feel of the hair bundle after the dyeing treatment was evaluated. The evaluation criteria are as follows. The evaluation results are shown in Tables 1 and 2.
Evaluation 5: The fingering was very good.
Evaluation 4: Fingering was good.
Evaluation 3: The finger passage was relatively good.
Evaluation 2: The fingering was slightly bad.
Evaluation 1: Fingering was very bad.

Evaluation 5: The brightness was very good.
Evaluation 4: Brightness was good.
Evaluation 3: The brightness was relatively good.
Evaluation 2: The brightness was slightly bad.
Evaluation 1: The brightness was very bad.

  From Table 1 and Table 2, in the hair dyeing composition of Comparative Example 1, since the blending amount of the component (B) is less than 1% by mass, the feeling after finishing (slip feeling) is slightly bad. Moreover, in the composition for hair dyeing of the comparative example 2, since the (B) component is not mix | blended, the touch (slip feeling) after a finish is very bad.

  On the other hand, according to the hair dyeing composition of the example, it was confirmed that the feeling after finishing (slip feeling) was good and the lightness after finishing was also good.

  And when Example is compared, in Example 5, (D) component (specific cationic polymer) is not mix | blended. Therefore, it is slightly inferior to the feeling after finishing (slip feeling) as compared with other examples.

  In Example 6, the final dosage form is creamy. In Examples other than Example 6, the final dosage form was foamy, and it was confirmed that the feeling after finishing was even better than Example 6.

  In Example 7, the mass ratio of the component (A) to the component (B) exceeds 4.5. On the other hand, in Examples other than Example 7, the mass ratio is in the range of 0.02 to 4.5, and the finished feel (slip feeling) is even better than Example 7. It was confirmed that.

  In Reference Examples 1 and 2, sodium metasilicate was used in place of the component (A). Compared to Reference Example 2, Reference Example 1 shows an improvement in feel after finishing due to suppression of the feel of the hair bundle after finishing becoming stiff and itchy, tangling hair, stiffness, etc. The effect of improving the feeling of slip after finishing by suppressing the rough feeling is not seen.

  Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention.
