Comparing Examples 6 to 8 and Comparative Examples 6 and 7, when the content of (c) the chelating agent is in the range of 0.5 to 2.0% by mass, the effect of improving the brightness and the hair dyeing power are excellent. was taken. On the other hand, when the content of the (c) chelating agent was less than 0.5% by mass, the effect of improving the brightness was significantly reduced, and when it exceeded 2.0% by mass, not only the effect of improving the brightness but also the hair dyeing power was significantly reduced. .
Also, looking at Comparative Examples 8 and 9, although the content of (c) the chelating agent was adjusted to 0.5 to 2.0, (a) branched esters and (b) oily oils that are liquid at 25 ° C. When the sum of the contents of the components was small (Comparative Example 8), the effect of improving the brightness was significantly reduced, and when it was large (Comparative Example 9), the hair dyeing power and application operability were significantly reduced. That is, in order to exhibit the brightness improvement effect, application operability, and hair dyeing power of the present invention in a well-balanced manner, it is necessary not only to adjust the content of (c) the chelating agent, but also (a) the branched ester and (b) 25 ° C. It is necessary to adjust the balance with the sum of the contents of the liquid oily components, and it can be said that excellent effects are achieved when (a+b)/c is in the range of 0.01 to 20.
Furthermore, in Examples 6 to 8, when the ratio [b/c] of the content of (b) the oily component that is liquid at 25°C to the content of the (c) chelating agent is in the range of 0.005 to 10, An excellent effect in improving brightness and hair dyeing power was observed. On the other hand, in Example 9 where b/c was less than 0.005, the effect of improving brightness was slightly reduced, and in Example 10 where b/c exceeded 10, hair dyeing power was slightly reduced.

Looking at Examples 11 to 15 in Table 3, the brightness improvement effect is obtained when the ratio [c/d] of the content of (c) chelating agent to the content of (d) 4APE salt is in the range of 0.2 to 80. , a particularly excellent effect in suppressing fading and in levelness of dyeing. On the other hand, in Example 13 where c/d is less than 0.2, the uniformity of dyeing is slightly lowered, and in Example 14 where c/d exceeds 80, the effect of suppressing fading is slightly lowered.

In Examples 16 to 20 in Table 4, the effect of the present invention was confirmed with respect to (d) a hair dye composition containing a salt of 4APE. improvement, and the effect of improving coating operability was recognized. In addition, excellent effects were also observed with respect to the effect of suppressing fading and the uniformity of dyeing.

Looking at Table 5, even when the components (a), (b) and (c) are contained in the second agent, the effect of improving the brightness and the application operation are the same as when they are contained in the first agent. It can be seen that the characteristics are excellent.
