[0002]

2. Description of the Related Art Conventionally, a hair decolorizing composition of this kind contains an alkaline agent such as ammonia, alkanolamine, or organic amine in order to promote the action of an oxidizing agent. ing. For this reason,
Ammonia odor is generated when the hair decolorizing composition is used.
In order to reduce the pungent odor of this ammonia-based hair bleaching composition, an alkanolamine such as monoethanolamine may be contained in place of ammonia. Then, the ammonia content is reduced by that amount, and the pungent odor of the hair decolorizing composition is reduced.

On the other hand, the hair dye composition is a two-pack type oxidative hair dye consisting of a first agent containing an oxidative dye intermediate as a dye and an alkali agent, and a second agent containing an oxidant. Are known. The alkaline agent is added to swell the hair to facilitate the penetration of the dye and the oxidizing agent into the hair and to promote the action of the oxidizing agent. Specific examples of the alkaline agent include those described in the above hair bleaching agent composition, but as with the hair bleaching agent composition, ammonia is generally used. Therefore, in order to reduce the irritating odor of the hair dye composition based on the odor of ammonia, an alkanolamine such as monoethanolamine may be contained instead of ammonia, as in the case of the hair bleaching composition.

(2) Lightness The hair after the decolorization treatment is visually observed, and as for lightness, excellent lightness (⊚), good lightness (∘), lightness slightly insufficient (Δ) and lightness insufficient ( Sensory evaluation was carried out in four stages of x).

(3) Feeling The feel when touching the hair bundle after the decolorization treatment was sensory-evaluated in four levels of excellent (⊚), good (∘), somewhat poor (Δ), and poor (x). .

[0074]

[Table 3]

As shown in Table 3, Examples 1 to 7 gave good results in terms of pungent odor, brightness and feel.

On the other hand, as shown in Table 3, Comparative Examples 1 and 4
Since it does not contain isoparaffin, its irritating odor was not reduced, and sufficient brightness was not obtained. In addition, Comparative Examples 2 and 5 did not contain a polymer compound, and thus the touch was not good. Comparative Examples 3 and 6 contained oily components other than isoparaffin, but did not contain isoparaffin, and thus were evaluated to have a slight pungent odor and slightly insufficient brightness. Furthermore, Comparative Example 7 was evaluated to have neither an irritating odor, nor an isoparaffin, and therefore had an irritating odor, insufficient lightness, and slightly poor feel.

(Examples 8 to 14 and Comparative Examples 8 to 14) As shown in Tables 4 and 5, Examples 8 to 14 and Comparative Examples 8 to 14 as a two-component type hair dye composition are as follows. The agent and the second agent were prepared. The pH of the second agents of Examples 8 to 14 and Comparative Examples 8 to 14 was adjusted to 3 with phosphoric acid after preparation. Further, the numerical values in Tables 4 and 5 are shown by weight%.

[Table 5]

With respect to the hair dye compositions in each row of Tables 4 and 5, the first agent and the second agent were mixed at a weight ratio of 1: 1 and then applied to the hair bundle. At this time, Examples 8 to 14 and Comparative Examples 8 to
14 is an oil-in-water emulsion, which is in the form of a cream.
Then, regarding the hair dye composition and the hair bundle after the hair dyeing treatment,
The following items (4) to (7) were evaluated. The evaluation results are shown in Table 6.

(4) Stimulating odor By sniffing the odor of the hair dye composition, there is no irritating odor (⊚), there is almost no irritating odor (○), there is a little irritating odor (Δ) and there is irritating odor ( Sensory evaluation was carried out in four stages of x).

(5) Lightness The hair after the hair dyeing treatment is visually observed, and regarding lightness, excellent lightness (⊚), good lightness (∘), lightness slightly insufficient (Δ) and lightness are insufficient. Sensory evaluation was carried out in four levels of (x).

(6) Hair dyeing power The hair after dyeing treatment is visually observed to find out the hair dyeing power.
A sensory evaluation was carried out on four levels: excellent hair dyeing power (⊚), good hair dyeing power (∘), slightly poor hair dyeing power (Δ) and considerably poor hair dyeing power (×).

(7) Tactile sensation When touching the hair bundle after the hair dyeing treatment with a hand, the sensory evaluation was carried out in four grades of excellent (⊚), good (∘), somewhat poor (Δ) and poor (x). did.

[0085]

[Table 6]

As shown in Table 6, Examples 8 to 14 gave good results in terms of pungent odor, brightness and feel.

On the other hand, as shown in Table 6, Comparative Examples 8 and 1
Since No. 1 did not contain isoparaffin, the pungent odor was not reduced, and sufficient brightness was not obtained. In addition, Comparative Examples 9 and 12 did not contain a polymer compound, and thus the touch was not good. Comparative Examples 10 and 13 contained an oily component other than isoparaffin, but did not contain isoparaffin, and thus were evaluated as having a slight pungent odor and slightly insufficient brightness. Furthermore, Comparative Example 14 was evaluated to have neither irritating odor, insufficient lightness, or slightly poor touch because it contained neither isoparaffin nor a polymer compound.
