表1に示すとおり、pH調整剤としてクエン酸・H2O 1gおよびクエン酸・三Na・2H2O 11gをイオン交換水に溶解し、pH6の水溶液(水+pH調整剤)1kgを調製した。得られたpH6の水溶液に、染料としてYellow 29と、浸透剤としてベンジルオキシエトキシエタノールとを、表2に示す組成で配合し、pH6の染毛料組成物を調製した。調製した染毛料組成物10gを量り取り、人毛白髪(100%、株式会社ビューラックス、商品番号BM-W-A)1gを入れて、45℃で20分間染色した。得られた染毛を水洗(15~25℃の流水、約1分間)し、下記ソーピング条件でソーピングを行った後、水洗(15~25℃の流水、約1分間)し、室温(約20℃)で自然乾燥することによって、試験検体を得た。なお、以下の実施例および比較例において、染毛料組成物のpH調整は、表1に基づいて行った。表中、濃度(g/kg)は水溶液中のpH調整剤の濃度を示す。
ソーピング液:5%ラウリル硫酸ナトリウム水溶液
浴比: 1:10(染毛質量1gに対するソーピング液質量)
処理温度:45℃
処理時間:5分
染料として、Yellow 29の代わりに、Yellow 57を用いた以外は実施例1と同様の方法により、試験検体を得た。なお、Yellow 57は、日本ヘアカラー工業会「染毛料に配合できる色素リスト」カテゴリーIIに掲載されている、下記式(III)に示す染料であり、Arianor Straw Yellowとして市販されている化合物である。
染料として、Yellow 29の代わりに、Yellow 87を用いた以外は実施例1と同様の方法により、試験検体を得た。なお、Yellow 87は、日本ヘアカラー工業会「染毛料に配合できる色素リスト」カテゴリーIIIに掲載されている、下記式(IV)に示す市販の染料である。
実施例1で得られたYellow 29の試験検体について、以下に示すシャンプー堅牢性試験を行い、試験前後の染着濃度(K/Sd)および色差(ΔE*)を測定した。結果を表4に示す。なお、表中、残存率(%)とは、試験前の染着濃度に対する試験後の染着濃度の比率を意味する。
試験検体に対し、下記(1)シャンプー処理の後(2)トリートメント処理を行う操作を5回繰り返した後、室温(約20℃)で自然乾燥した。
(1)シャンプー処理条件
シャンプー液:5%ラウリル硫酸ナトリウム水溶液
浴比: 1:10(染毛質量1gに対するシャンプー液質量)

処理温度: 45℃
処理時間: 20分
後処理: 水洗
比較例2で得られたYellow 87の試験検体について、実施例2と同様にシャンプー堅牢性試験を行い、試験前後の染着濃度(K/Sd)および色差(ΔE*)を測定した。結果を表4に示す。
表1に従いpH5、pH7の水溶液を調製し、pH6の水溶液の代わりにそれぞれpH5、pH7の水溶液を用いて染毛料組成物を調製した以外は、実施例1(染料:Yellow 29)と同様の方法により試験検体を得た。得られた試験検体の染着濃度(K/Sd)および色味(L*、a*、b*)を求めた。結果を表5に示す。
実施例3、実施例4において、ベンジルオキシエトキシエタノール(浸透剤)を使用しない以外はそれぞれ実施例3、実施例4と同様の方法により試験検体を得た。得られた試験検体の染着濃度(K/Sd)および色味(L*、a*、b*)を求めた。結果を表5に示す。
