[First Example Group: Oxidative hair dye]
(Preparation of oxidative hair dye)
Example 1 to Example 17 of the composition shown in the last Table 1 to Table 3, the first hair dye of the composition according to Comparative Example 1 to Comparative Example 14, and the hair dye of the composition shown in Table 4 at the end. A second agent was prepared according to a conventional method. In these tables, the content of each component is expressed as a numerical value in units of mass%. In addition, in the component name column in the table, for example, “(A)” before the component name indicates that the component is (A) component, and “(A ratio)”. Indicates that the component is a component for comparison with the component (A). In addition, the notation “(C)” represents the fragrance compound shown in “Chemical 6” or “Chemical 7”, and the notation “(C ratio)” is “Chemical 6” or “Chemical 7”. The product name “Polysantol” manufactured by Firmenich was specifically used as (C ratio).

  The contents of the first agent for oxidative hair dye according to each example and comparative example are as follows.

  (1) Examples 1 to 5 and Comparative Examples 1 to 2 shown in Table 1 are the types and contents of (A), (B), (D), (E), (F) and other components. Although the amount is the same, only the perfume ingredients are different. That is, Examples 1 to 4 each contain one kind of fragrance compound shown in “Chemical Formula 6” or “Chemical Formula 7”, and Example 5 contains two kinds of those fragrance compounds. Comparative Example 1 Does not contain a fragrance, and Comparative Example 2 contains a fragrance that is “(C ratio)”.

  (2) Examples 6 to 11 and Comparative Examples 3 to 7 shown in Table 2 are the same as those shown in Table 2 without changing the type and content of the fragrance compound. In this example, the types and contents of the component (A) and the component (B) are variously changed, or these components are omitted or replaced with comparative components. Therefore, there are examples in which the in-use mass ratio of (B) / (A) is different from that in Example 1, and examples where (B) / (A) cannot be calculated. In addition, the comparative example 8 shown in Table 2 is a thing of the composition which made the fragrance | flavor compound missing from the comparative example 7.

  (3) Examples 12 to 17 and Comparative Examples 9 to 13 shown in Table 3 are the same as Example 4 shown in Table 2 without changing the type and content of the fragrance compound. In this example, the types and contents of the component (A) and the component (B) are variously changed, or these components are omitted or replaced with comparative components. Therefore, there are examples in which the in-use mass ratio of (B) / (A) is different from that in Example 4 and examples where (B) / (A) cannot be calculated. In addition, Comparative Example 14 shown in Table 3 has a composition in which the fragrance compound is further omitted from Comparative Example 13.

(Evaluation in oxidation hair treatment)
The first hair dye agent according to each of the above Examples and Comparative Examples was mixed with the second hair dye agent at a mass ratio of 1: 1. It was applied to the hair bundle, left for 30 minutes, washed with water and dried. With respect to the dried hair bundle, the effect of reducing the reaction odor (residual odor) of hair was evaluated by 10 panelists.

  The reaction odor (residual odor) reduction effect is evaluated by a score method. “Excellent” is 5 points, “Excellent” is 4 points, “Good” is 3 points, “Slightly bad” is 2 points, “Bad” is One point was set. And the average value of the score of 10 panelists is calculated for each example and each comparative example. If the average value is 4.6 points or more, the highest rank is “5”, and the average value is 3.6 points to 4 points. If the average value is 2.6 points to 3.5 points, the rank is "4". If the average value is 2.6 points to 3.5 points, the rank is "3". If the average value is 1.6 points to 2.5 points, the rank is "2". If the average value is 1.5 points or less, the lowest rank is “1”. These ranks are shown in Tables 1 to 3.

[Second Example Group: bleaching agent]
The bleaching agent 1st agent of the composition which only removes "paraphenylenediamine" from the composition which concerns on Example 1- Example 5 and Comparative Example 1- Comparative Example 2 which are shown in the last Table 1 is prepared, respectively. The mixture was applied to the hair bundle of human hair and mixed with the second agent shown in No. 4 at a mass ratio of 1: 1, and the reaction odor (residual odor) of the hair as in the case of the first example group. The reduction effect was evaluated.

  The results of evaluation were omitted to avoid unnecessary duplication, but were completely equivalent to Examples 1 to 5 and Comparative Examples 1 to 2 in the first example group.
