There is a possibility that the dye described below cannot be sufficiently oxidized. On the other hand, if the amount is more than 15.0% by weight, hair may be damaged or other troubles may occur.

Phenoxyethanol as the component (B) is added as a stabilizer for hydrogen peroxide in order to suppress decomposition of hydrogen peroxide. The content of the component (B) in the second agent is preferably 0.001 to 1.0% by weight, more preferably 0.005 to 0.5% by weight, and most preferably 0.01 to 0.3% by weight. %.

EXAMPLES Next, the above-mentioned embodiment will be described more specifically with reference to Examples and Comparative Examples. (Examples 1 to 8 and Comparative Examples 1 to 3) The first agent and the second agent of the hair dye shown in Table 1 were prepared. Next, the second agent was evaluated for the items (1) and (2) below. Then, the 1st agent and the 2nd agent were mixed and the hair dyeing process was performed by applying to a hair bundle. The hair bundles after this hair dyeing treatment were evaluated in the items (3) and (4) below. The results of these evaluations are shown in Table 1.

The first agent and the second agent are mixed in a weight ratio of 1: 1. The numerical values in Table 1 are% by weight, POE is polyoxyethylene, and the numerical values in parentheses accompanying POE are the average number of moles of ethylene oxide added.

(1) Stability of Hydrogen Peroxide The second agent of each example was stored in a thermostatic chamber at 45 ° C. for 1 month, and the amount of residual hydrogen peroxide was quantified by a redox titration method. Was calculated. The evaluation is excellent (⊚) when the residual rate is 96% or more, good (○) when 94% or more and less than 96%, and somewhat poor (△) when 94% or more and less than 94%.
And less than 92% were evaluated as poor (x) on a four-point scale.

(2) Solubility of Phenoxyethanol By visually observing the transparency of the second agent of each example, the solubility of phenoxyethanol was excellent (⊚), good (∘), slightly poor (Δ) and poor (×). ) The sensory evaluation was performed in four steps.

(3) Feeling The feel of the hair bundle when touched with hands is excellent (⊚), good (∘),

(4) Lightness By visually observing the hair bundle, regarding the lightness of the hair, excellent lightness (⊚), good lightness (∘), and slightly insufficient lightness (△)
And the lightness was insufficient (x), and sensory evaluation was performed on four levels.

[0073]

[Table 1] As is clear from the results in Table 1, in Examples 1 to 8, all the hydrogen peroxide remained at 94% or more, which was a good result regarding the stability of the hydrogen peroxide. Further, in Examples 1 to 8, the solubility of phenoxyethanol was excellent or good. On the other hand, in Comparative Example 1,
Since the component (C) was not blended, the residual ratio of hydrogen peroxide was less than 92%, and the stability of hydrogen peroxide was poor. In Comparative Example 2, since the component (D) was not blended, the solubility of phenoxyethanol was poor, and the stability of hydrogen peroxide was somewhat poor. Further, in Comparative Example 3, since the component (B) was not blended, the stability of hydrogen peroxide was poor.

In Example 3, since the component (F) is blended, it can be seen that the feel is improved. In addition, since the stability of hydrogen peroxide in Example 3 is not lower than that in Example 1, it can be seen that the component (F) does not easily impair the stability of hydrogen peroxide. In Example 4, since the content of the component (B) is as low as 0.007% by weight, the stability of hydrogen peroxide is slightly lowered.

In Example 5, the content of the component (D) was 3.
Since it is as high as 0% by weight, the brightness is slightly lower than that in Example 3. In Examples 6 and 7, the ratio of 1-hydroxyethane-1,1-diphosphonic acid and its salt was 3: 1 and 1: 3, and therefore the solubility of phenoxyethanol was slightly reduced as compared with Example 3. However, the stability of hydrogen peroxide is slightly reduced. In Example 8, since 1-hydroxyethane-1,1-diphosphonate was not blended,
Compared with Example 3, the solubility of phenoxyethanol is slightly reduced, and the stability of hydrogen peroxide is also slightly reduced. (Examples 9 to 16 and Comparative Examples 4 to 6) The first and second agents of the permanent wave agent shown in Table 2 were prepared. Next, the second agent was evaluated for the items (1) and (2). Then, the 1st agent of each example and the 2nd agent were combined and used for the permanent wave treatment of hair.

For the permanent wave treatment, a hair bundle (30 bundles, length: 15 cm) made from hair of a Japanese woman in her twenties that had not been chemically treated was used.
In the permanent wave treatment, first, a rod having a diameter of 1 cm was wound around the hair bundle, the first agent was applied, and the hair was left at 37 ° C. for 15 minutes. Then, the second agent was applied and left at room temperature for 15 minutes, then washed with water and dried.

With respect to the hair bundle after the permanent wave treatment, the above item (3) and the following item (5) were evaluated. The results of these evaluations are shown in Table 2. (5) Elasticity of wave Elasticity when the hair bundle after the permanent wave treatment is touched by hand is classified into four levels of excellent (◎), good (○), slightly poor (△) and poor (×). evaluated.

The first agent and the second agent are used in a weight ratio of 1: 1. The numerical values in Table 2 are% by weight, POE is polyoxyethylene, and the numerical values in parentheses accompanying POE are the average number of moles of ethylene oxide added.

[0079]

[Table 2] As is clear from the results in Table 2, in Examples 9 to 16 as well as in Examples 1 to 8, the stability of hydrogen peroxide and the solubility of phenoxyethanol were good. In Examples 11 to 16, since the component (F) was blended, the feel and the elasticity of the wave were improved.
