<Hair dyeing power>
(Method for dyeing hair with hair dye composition)
1 g of the hair dye composition according to each example was applied to 1 g of hair tresses with a brush and allowed to stand at 30° C. for 10 minutes. Thereafter, the hair tress was washed with Bigen Treatment Shampoo (manufactured by Hoyu Co., Ltd.) to wash off the hair dye composition. Next, Bigen Treatment Rinse (manufactured by Hoyu Co., Ltd.) was applied to the hair tress. After rinsing the tresses and washing away the Bigen Treatment Rinse, the tresses were wiped dry with a towel and finally dried with a drier.

Ten panelists visually observed the dyed state of the hair tresses dyed as described above. In the visual evaluation, the hair dyeing power was evaluated according to the following evaluation criteria, and the average value of the evaluation scores of 10 panelists was rounded off to give the evaluation score of each hair dye composition. In evaluating the hair dyeing power, the hair dyeing power of Comparative Example 3 was evaluated as 1: very low. Then, the hair dyeing power was evaluated according to the following evaluation criteria, and the average value of the evaluation scores of the 10 panelists was rounded off to obtain the evaluation score of each hair dyeing power.

<Formulation stability>
After preparing the hair dye composition, 30 g was weighed into a No. 4 standard bottle, stored at 40° C. for 1 month, and the presence or absence of separation and precipitation of ingredients was visually evaluated according to the following evaluation criteria. The viscosity was measured for each dye composition at 25° C. using a Brookfield viscometer, and evaluated by comparing the viscosity before and after storage.

A rubber packaging material (squeezed rubber, material: nitrile rubber) was immersed in the hair dye composition according to each example and stored at 40° C. for 1 month, and then the degree of swelling of the rubber packaging material was visually evaluated. When no swelling of the rubber packaging material was observed, the stability of the packaging material was evaluated as high, and when the swelling was large, the stability of the packaging material was evaluated as low. In the evaluation of the stability of the packaging material, the stability of the packaging material of Example 10 was evaluated as 3: Slightly high stability of the packaging material. Then, the stability of the packaging material was evaluated according to the following evaluation criteria, and the value obtained by rounding off the average value of the evaluation scores of the 10 panelists was used as the evaluation score of the stability of each packaging material.

Polyacrylamide shown in Table 4, (Na acrylate / Na acryloyldimethyltaurate) copolymer, a hair dye composition containing three thickening agents xanthan gum was prepared, and the hair dyeing power and formulation stability were obtained in the same manner as in Experiments 1 and 2. It was tested for durability, packaging material stability, and quick-drying property. Table 4 shows the results of the test.

As a result of the experiment, it was observed that Example 1 containing polyacrylamide, which is a homopolymer of acrylic monomers, exhibited particularly high hair dyeing power, formulation stability, and quick-drying properties at the same time. In addition, as compared with Example 1, Example 15 containing a (Na acrylate/Na acryloyldimethyltaurate) copolymer, which is a copolymer of acrylic monomers, showed a similar effect although the formulation stability was slightly inferior. On the other hand, xanthan gum, which is a natural compound, was shown to be inferior in hair dyeing power and quick-drying property.
