実施例1~15及び比較例1で得られた泡状の剤型の各染毛剤を黒毛のウィッグに刷毛を用いて塗布し、室温(25℃)にて30分間放置した。次に、ウィッグに付着した染毛剤を水で洗い流した後、ウィッグにシャンプーを2回、及びリンスを1回施した。続いて、ウィッグを温風で乾燥した後、一日間放置することにより染色処理ウィッグを得た。こうして得られた各染色処理ウィッグを20名のパネラーが標準光源下で目視にて観察し、発色が良いか否かを判断した。発色が良いと答えたパネラーの人数が20人中17人以上であった場合には5、13~16人であった場合には4、9~12人であった場合には3、5~8人であった場合には2、4人以下であった場合には1と評価した。評価結果を表1の“染毛力の評価”欄に示す。 <Hair dyeing power>
Each of the foamy hair dyes obtained in Examples 1 to 15 and Comparative Example 1 was applied to a black wig using a brush and allowed to stand at room temperature (25 ° C.) for 30 minutes. Next, after the hair dye adhering to the wig was washed away with water, the wig was shampooed twice and rinsed once. Subsequently, the wig was dried with warm air and allowed to stand for one day to obtain a dyed wig. Each dyed wig thus obtained was visually observed by 20 panelists under a standard light source to determine whether or not the color development was good. 5 if the number of panelists who answered that color development was good was 17 or more out of 20, 4 if it was 13-16, 4, 5 if it was 9-12 When it was 8 people, it was evaluated as 1 when it was 2 or 4 people. The evaluation results are shown in the column “Evaluation of hair dyeing power” in Table 1.
実施例15及び比較例1で得られた泡状の剤型の各染毛剤を黒毛のウィッグに刷毛を用いて塗布する際のアンモニア臭について、臭気がない(5点)、臭気がほとんどない(4点)、臭気が少ない(3点)、やや臭気がある(2点)及び臭気がある(1点)の5段階で20名のパネラーが採点した。この採点結果の平均値が4.6点以上を「優れる:5」、3.6点以上4.6点未満を「良好:4」、2.6点以上3.6点未満を「可:3」、1.6点以上2.6点未満を「やや不良:2」及び1点以上1.6点未満を「不良:1」と評価した。評価結果を表1の“臭気の評価”とした。 <Odor>
About the ammonia odor at the time of apply | coating each hair dye of the foam-like dosage form obtained in Example 15 and Comparative Example 1 to the black wig using a brush, there is no odor (5 points) and there is almost no odor. 20 panelists scored in 5 stages (4 points), low odor (3 points), slightly odor (2 points) and odor (1 point). The average value of the scoring results is 4.6 points or higher as “excellent: 5”, 3.6 points or higher and lower than 4.6 points as “good: 4”, 2.6 points or higher and lower than 3.6 points as “good: 3 ”, 1.6 points or more and less than 2.6 points were evaluated as“ slightly poor: 2 ”and 1 point or more and less than 1.6 points were evaluated as“ defective: 1 ”. The evaluation results are shown in Table 1 as “Odor evaluation”.
実施例1~15及び比較例1の各染毛剤の第1剤及び第2剤のそれぞれを150mLの容器中に約100mL入れ、BL型粘度計VISCOMETER(東機産業株式会社製)を使用して25℃及び1分間の条件で粘度の値を測定した。ロータ及びモータの回転数は、本機器の測定可能な粘度範囲に従い選択した。尚、比較例1の染毛剤の第1剤は粉末状の剤型であるため粘度を測定していない。測定結果を表1の“第1剤の粘度”欄及び“第2剤の粘度”欄に示す。 <Viscosity>
About 100 mL of each of the first and second agents of each hair dye of Examples 1 to 15 and Comparative Example 1 was placed in a 150 mL container, and a BL type viscometer VISCOMETER (manufactured by Toki Sangyo Co., Ltd.) was used. The viscosity value was measured at 25 ° C. for 1 minute. The number of rotations of the rotor and motor was selected according to the measurable viscosity range of the instrument. In addition, since the 1st agent of the hair dye of the comparative example 1 is a powdery dosage form, the viscosity is not measured. The measurement results are shown in the “viscosity of the first agent” column and the “viscosity of the second agent” column in Table 1.
