The method of using the oxidative hair dye composition of the present invention is characterized in that the oxidative hair dye composition is left to stand for 5 minutes or more after being applied to the hair. Here, "after application to hair" means "after completion of the step of applying the oxidative hair dye composition to hair". According to the method of use of the oxidative hair dye composition, after 5 minutes, the difference in the finish of the hair dyeing due to the length of the hair dyeing treatment time becomes small, so the same is true even if the hair dyeing treatment time is prolonged It can be finished in density.

EXAMPLES Hereinafter, the present invention will be specifically described by way of examples, but the technical scope of the present invention is not limited by these examples.

[Evaluation method]
Hair dyeability
(Coloring treatment method)
The first agent and the second agent shown in Tables 1 and 2 were mixed in a ratio of 1: 1 to prepare an oxidative hair dye composition.
Three times the weight of the hair bundle weight was applied to a dry hair bundle (Beaurax white hair bundle (10 cm)) with a brush to apply an oxidative hair dye composition, and left at 30 ° C. for 10 minutes. The treated hair bundles were washed with water and then twice with a shampoo to wash away the oxidized hair dye composition. Next, a conditioner was applied to each hair bundle, and after the conditioner was washed away, the moisture of each hair bundle was wiped off with a towel and finally dried with a dryer.

(Evaluation method of hair dye)
With regard to the hair bundle subjected to the hair dyeing process of each of the above examples, five panelists visually evaluated the degree of color development under a standard light source based on the following criteria to determine whether color development is good or not. Although better dyed than Example 1 (6 points), level equivalent to Example 1 (staining is sufficient and reference value) (5 points), slightly lower than Example 1, no problem as dye (4 points) , Staining is reduced, but within the permissible range (3 points), the staining is significantly reduced, out of the permissible range (the color tone is maintained) (2 points) and the staining is significantly reduced, and the color is produced. It can not be) (1 point) and it scores in six steps, and made it an evaluation result. The results are shown in Tables 1 and 2.

(Background dirt prevention)
Similarly to the above, the first agent and the second agent shown in Tables 1 and 2 are mixed in a 1: 1 ratio, and 0.1 g of the oxidized hair dye composition is applied to the inner side of the arm in a circular shape of 1 cm in diameter. After standing for a minute, it was washed with water. Furthermore, the applied portion was washed twice using the above-mentioned shampoo composition. The inside of the arm at this time was visually observed by five panelists, and evaluated based on the following criteria to determine whether the ground was not easily soiled.
Background stains are suppressed more than Example 1 (5 points), equivalent to Example 1 (Sufficient as background stain degree is a reference value) (4 points), although slightly worse than Example 1, background stain degree As in the allowable range (3 points), the background dirt gets worse, out of the tolerance range 2 (2 points), and the background dirt gets significantly worse, and the pigment remains on the skin for a long time after washing (1 point) 5 It scored at the stage and made it the evaluation result. The results are shown in Tables 1 and 2.

Looking at Table 1, in Examples 1 to 3, (A) potassium iodide, (B-1) p-toluylenediamine or a salt of p-toluylenediamine is contained in a specific amount, (B-1) and (B-2) The oxidation hair dye composition having a total content of p-phenylenediamine of 0.5 to 2% by mass, and a pH of 9.0 or more, so that it is excellent in hair dyeability, and The effect of being able to control background dirt was recognized. On the other hand, (A) Comparative Example 1 which does not contain potassium iodide and Comparative Example 5 in which the pH is less than 9.0 are inferior in hair dyeing properties to Examples 1 to 3. Furthermore, the comparative example 2 which does not contain (B-1) p-toluylene diamine, and the comparative example 3 whose content of the sum total of (B-1) and (B-2) is more than 2 mass% suppresses background dirt. In Comparative Example 4 in which the total content of (B-1) and (B-2) is less than 0.5% by mass, it can be understood that the hair dyeability is inferior.
That is, as in Examples 1 to 3, (A) potassium iodide, (B-1) p-toluylene diamine, or a salt of p-toluylene diamine is contained in a specific amount, and (B-1) and (B) B-2) The oxidative hair dye composition having a total content of p-phenylenediamine and / or a salt thereof of 0.5 to 2% by mass and having a pH of 9.0 or more It can be understood that the effect is exhibited.

  Looking at Table 2, by controlling the total content of (B-1) and (B-2) to 0.5 to 2% by mass, the hair dyeing power is controlled more finely while suppressing soiling on the skin. be able to. Furthermore, it can be understood from Examples 1, 5 and 8 that even if the content of p-phenylenediamine is reduced, excellent hair dyeing effects can be exhibited.

The oxidative hair dye composition of the present invention can be used as a hair dye for dyeing body hair such as human hair, eyebrows, eyebrows and shin hair. In addition, it may be used to dye the hair of animals such as pets.
The oxidative hair dye composition of the present invention can be used as a hair dye for coloring in a beauty salon, a barber shop or the like, and a hair dye for self coloring.

  In addition, the method of using the oxidative hair dye composition of the present invention can be used for the hair dyeing treatment and self-coloring of hair in a beauty salon, a barber's room or the like.
