また、高級脂肪酸塩類、アルキルベンゼンスルホン酸塩類、リン酸エステル類、アルキル硫酸塩類、アルキル硫酸エステル塩類、ポリオキシエチレンアルキル硫酸エステル塩類等のアニオン性界面活性剤、アミノ酸類、アルキルトリメチルアンモニウム塩、ジアルキルジメチルアンモニウム塩、アルキルジメチルアミンオキサイド等のカチオン性界面活性剤、その他の界面活性剤を配合することもできる。
高分子化合物としては、ポリ(ジメチルアリルアンモニウムハライド)型カチオン性高分子、ポリエチレングリコール、エピクロルヒドリン、プロピレンアミン及び牛脂脂肪酸より得られるタロイルアミンの縮合生成物型であるカチオン性高分子、ポリエチレングリコール、エピクロルヒドリン、ビニルピロリドン、ジメチルアミノメタアクリレート共重合体型カチオン性高分子、第4級窒素含有セルロースエーテル型カチオン性高分子類等が挙げられる。
その他、香料、薬剤、着色剤、紫外線防止剤、水等を配合することもできる。これらは、必要に応じ適宜選択されて配合され、特に限定されるものではない。
そして、評価項目(1)について、下記採点基準にて評価すると共に、第1剤と第2剤との混合時にpHを測定した。結果を表1に示す。
(第1剤)
全成分を攪拌下80℃に加温して溶解、乳化した後、冷却することにより、第1剤を得た。
(第2剤)
過酸化水素以外の成分を攪拌下80℃に加温して溶解、乳化した後40℃まで冷却した時点で過酸化水素を加え、均一になるまで攪拌することにより、第2剤を得た。
第1剤10gと第2剤10gとをよく混合し、1g白髪毛束を混合液中に含浸させた。室温下で30分放置した後、毛束をぬるま湯でよく洗浄し、乾燥させた。
基準試験の毛束の染まりを基準(5)として、試験例の毛束の染まりを目視にて5段階の官能評価により判定した。
5・・・基準試験の毛束と同等。
4・・・基準試験の毛束よりわずかに薄い。
3・・・基準試験の毛束よりやや薄い。
2・・・基準試験の毛束より薄い。
1・・・基準試験の毛束よりかなり薄い。
しかし、基準試験と同じ組成の試験例1-1~1-3によれば、第1剤のpHを下げていき、組成物のpHが低下すると共に、染毛効果が低くなった。
また、従来、染毛効果を高める成分と知られている微生物由来ヒアルロン酸を配合しても、その効果は高いpH領域でのみ有効であり、低いpH領域では染毛効果に劣ってしまうことが明らかとなった。
下記表2に示す配合組成なる酸化染毛剤組成物(第1剤及び第2剤)を、上記製造方法により製造した。なお、第1剤のpHは、示されているpHになるように、pH調整剤を適宜配合することにより調整された。
そして、評価項目(1)について、上記採点基準にて評価すると共に、第1剤と第2剤との混合時にpHを測定した。結果を表2に示す。
したがって、本発明にかかる酸化染毛剤組成物において、アセチル化ヒアルロン酸ナトリウムを含有させることが必要である。
このため、本発明の酸化染毛剤組成物は、毛髪への損傷の軽減を考慮すると、第1剤のpHが8~11でかつ、第1剤と第2剤を等重量で混合したときのpHが8~10に調整されることが好適である。
また、本発明の酸化染毛剤組成物は、pHを1程度低くしても、従来のpHが1高い酸化染毛剤と同等もしくはそれ以上の染毛効果が期待できることも明らかとなった。
下記表3に示す配合組成なる酸化染毛剤組成物(第1剤及び第2剤)を、上記製造方法により製造した。そして、評価項目(2)及び(3)について下記採点基準にて評価した。結果を表3に示す。
第1剤10gと第2剤10gとをよく混合し、1g白髪毛束を混合液中に含浸させた。室温下で30分放置した後、毛束をぬるま湯でよく洗浄し、乾燥させた。
コントロールの毛束を基準(0)として、試験例の毛束の染まりを目視にて5段階の官能評価により判定した。
4・・・コントロールの毛束よりかなりよく染まっている。
3・・・コントロールの毛束よりよく染まっている。
2・・・コントロールの毛束より染まっている。
1・・・コントロールの毛束よりわずかに染まっている。
0・・・コントロールの毛束と同等。
評価項目(2)で染色した毛束を80%RH下で12時間放置した後、重量(W1)を測定した。そして、同じ毛束を2時間減圧乾燥した後、重量(W2)を測定した。これらの測定値により、下記に示す水分保持率を算出した。
水分保持率(%)=(W1-W2)×100/W1
これに対して、コントロールの酸化染毛剤に試験例3-1、3-2と同量のアセチル化ヒアルロン酸ナトリウムを配合した試験例3-3の試料は、上記の結果と同様、染毛効果に優れていた。
アセチル化ヒアルロン酸の配合量が少ない試験例3-4においても、試験例3-1、3-2より染毛効果に優れていた。
また、試験例3-5、3-6によれば、アセチル化ヒアルロン酸の配合量を増加させることにより、染毛効果を向上できることがわかった。
また、試験例3-7~3-9によれば、アセチル化ヒアルロン酸ナトリウムを配合した酸化染毛剤に、さらにイソステアリルアルコール及び/又はオレイン酸デシルを配合した試料は、染毛効果に非常に優れていた。
また、試験例3-2及び試験例3-3における水分保持試験によれば、本発明にかかるアセチル化ヒアルロン酸ナトリウムを配合した酸化染毛剤組成物を用いて染毛した毛髪の染毛後の水分保持率が高いことも明らかとなった。
