Abstract
Description
メタノールの割合は、GC−FID(Gas Chromatography Flame Ionization Detector)方式で確認した。測定機器としては、Agilent Technologies社の7890B GC System製品を使用し、試料をACN(Acetonitrile)に希釈してメタノールの割合を確認した。前記メタノールの割合確認時の測定条件は、下記通りである。
測定器:7890B GC System(Agilent Technologies)
カラム:HP−FFAP(19091F−115)(50m*320μm*0.5μm)
Injector templerautre:220℃
Oven temperature:60℃/10min−25℃/min−220℃/13min
流速:1.5mL/min
Injection volume:1.5μL injection
カラム:C18(5μm、4.6*250mm)
移動相:ACN:Water=60:40
Oven temperature:30℃
Injection volume:10μL
Detection:360nm
重量平均分子量(Mw)及び分子量分布(PDI)は、GPCを使用して以下の条件で測定し、検量線の作製には、Agilent systemの標準ポリスチレンを使用して測定結果を換算した。
測定器:Agilent GPC(Agilent1200 series、U.S.)
カラム:PL Mixed B 2つを連結
カラム温度:40℃
溶離液:THF(Tetrahydrofuran)
流速:1.0mL/min
濃度:〜1mg/mL(100μL injection)
ガラス転移温度(Tg)は、単量体組成に基づいて下記数式により算出した。
1/Tg=ΣWn/Tn
にじみの評価は、次のような方式で行った。先ず、ガラス板上に試料(マスカラ剤型)を約100μm程度の厚さで塗布後、25℃で24時間乾燥した。その後、乾燥された試料の約4cm2の面積上に人工皮脂0.1gを落とし、10分間wettingを行った後、その上に紙を載せて、500gのおもりで20回水平往復運動を行い、紙に人工皮脂がにじみ出る程度をイメージ分析を行った。
粉落ちの評価は、次のような方式で行った。先ず、人毛遊離ストランドにマスカラ剤型を10回ずつ塗布し、乾燥した後に乾燥した人毛サンプルを25℃の蒸留水に5秒間浸した後に取り出した。人毛を3分乾燥した後、ナイロンブラシを使用して振幅を2cm以内で20回摩擦を加えて落ちる粉のイメージ分析を介して比較した。粉落ちの数値は、人毛ストランドに剤型を塗布し、乾燥した後に水に浸してから取り出して摩擦を加えて落ちる粉の個数を測定した値である。
専門評価パネル20名(25〜50歳)によるマスカラの使用テストを行った。パネルにマスカラを塗布した後、6時間後ににじみ(皮脂ににじみ出る程度)及び粉落ちの程度を下記基準により5段階と評価し、その平均で判断した。
A:平均4.5点以上
B:平均3.5点以上、4.5点未満
C:平均2.5点以上、3.5点未満
D:平均2.5点未満
<スコア評価基準>
<にじみの評価>
5点:にじみなし
4点:ややにじみ
3点:普通
2点:にじみが激しい
1点:にじみが非常に激しい
<粉落ちの評価>
5点:粉落ちなし
4点:粉落ちが少ない
3点:普通
2点:粉落ちが多い
1点:粉落ちが非常に多い
