(1)前処理
試料に、炭化水素油(B)及び/又は非反応性シリコーン油(C)を含有している場合、試料10gとヘキサン40gとを混合した後、遠心分離(2880G、10分間)して固体{疎水性シリカ(A)を含む。}と液体{ヘキサンと炭化水素油(B)及び/又は非反応性シリコーン油(C)とを含む}とを分離し、次いで、固体{疎水性シリカ(A)を含む。}とヘキサン40gとを混合し、遠心分離により固体と液体とを分離して、さらに同様の混合及び遠心分離の操作を3回繰り返した後、固体に残存しているヘキサンを120℃、2時間加熱乾燥させることにより、測定試料を得る。
一方、試料に疎水性有機溶剤を含有している場合、試料を加熱乾燥(120℃、2時間)することにより、疎水性有機溶剤を除去して測定試料を得る。
メタノール濃度を2.5容量%の間隔で変化させた水/メタノール混合溶液を調製し、各混合溶液5mlを別々の10ml試験管に入れ、次いで測定試料0.2gを入れ、試験管にふたをして、20回上下転倒してから静置した後、凝集物を観察して、凝集物がなく、測定試料の全部が湿潤して均一混合した混合溶液のうち、メタノール濃度が最も小さい混合溶液のメタノールの濃度(容量%)を疎水化度[M値]とする。
体積比80/20のメタノール/イオン交換水の溶液に、水酸化ナトリウムが飽和濃度で溶解したメタノール/イオン交換水溶液(体積比80/20)を加えて、pH13に調整した後、この溶液50mlに測定試料{炭化水素油(B)及び/又は非反応性シリコーン油(C)を含有している場合、上記の前処理したもの}0.5gを混合し、25℃で1時間静置し、固体を遠心分離(2880G、10分間)し、固体とメタノール40gとを混合し、遠心分離する洗浄操作を3回行い、120℃で2時間加熱乾燥した後、上記の疎水化度の測定と同様にして疎水化度を測定する。
なお、変化率(MY/MX)は、疎水化度[M値(MY)]を疎水化度[M値(MX)]で除して算出される。
疎水化剤の疎水性度が低い程、疎水化度[M値(MX)]は小さくなる傾向があり、疎水化剤の疎水性度が高い程、疎水化度[M値(MX)]は大きくなる傾向がある。そして、上記の疎水化剤を用いることにより、上記の疎水化度[M値(MX)]にできる。
なお、試料に、炭化水素油(B)、非反応性シリコーン油(C)及びポリオキシアルキレン化合物(D)からなる群より選ばれる少なくとも1種の液体や疎水性有機溶剤を含有している場合、<疎水化度[M値(MX)、(MY)]の測定法>の(1)前処理と同様にして、測定試料を前処理する。
