モノメチルアミン41%水溶液244gと、2-クロロエトキシエタノール182g、水80gを耐圧反応容器に入れ、110℃で4時間反応させた後、水酸化ナトリウム水溶液(等量対クロロ体)を加え、生成した塩酸を中和し、過剰のモノメチルアミンを減圧除去した。反応混合物を別の反応容器に移し、2-クロロエトキシエタノールをさらに86g追加して80℃にて1時間反応させた後、追加した2-クロロエトキシエタノールと等量の水酸化ナトリウム水溶液を30分かけて滴下した。30分熟成させた後、溶媒および塩を除去し、蒸留により、ジ体(ビス(2-エトキシエタノール)メチルアミン)を単離した。生成物はNMR(400MHz、1H、Varian社製、Mercury400)により確認した。続いて得られたジ体113gとステアリン酸326gを180~200℃、180~200Torr(24.0~26.7kPa)で23時間反応させ、ビス(2-エトキシエタノール)メチルアミンのジエステル化物を得た。次に、得られたジエステル化物44gをイソプロピルアルコール50gに溶解し、耐圧容器に仕込んだ後、メチルクロライド4.5gを加え、88℃にて5.5時間反応させ、四級化した。反応混合物を冷アセトン中で晶析させ、乾燥させることで、一般式(I)で表わされる第四級アンモニウム塩〔化合物(I-1)〕を得た。生成物の同定は、NMR(400MHz、1H)および油脂分析(酸価(JIS K 0070)、けん化価(JIS K 0070)、水酸基価(JIS K 0070)、アミン価(ASTM D 2074)、塩化物イオン濃度(硝酸銀滴定法)、乾燥減量測定(乾燥法))により行った。この化合物(I-1)の構造を表1に示す。

製造例1~5で製造した化合物(I-1)~(I-4)及び化合物(II-1)と、塩化カルシウムとを、表2の組成でイオン交換水に分散させて、液体柔軟剤組成物を調製し、これら液体柔軟剤組成物の(1)分散性及びハンドリング性、(2)柔軟性及び吸水性を下記評価法に従い評価した。
(1)分散性及びハンドリング性
分散液の調製時の容易さから分散性を評価した。すなわち、所定量の塩化カルシウムを含む約70℃に加熱した水に、所定量の第四級アンモニウム塩(I)又は第四級アンモニウム塩(I)及び(II)を添加し、激しく攪拌した。その際、攪拌開始後3分以内に混合物が均一になるものを分散容易とし、攪拌開始から均一になるまで3分以上を要したものを、分散困難と評価した。更に、調製後の増粘の様子を観察した。調製後、室温まで冷却しても流動性を有するものをハンドリング性良好、液体状態であるものはハンドリング性非常に良好と判断した。結果を表2にまとめて示す。ここで、流動性を有するとは、分散液15mlを、直径25mm、高さ55mmの円筒形ガラス瓶に入れ、25℃ですばやく水平にしたとき、30秒以内に液面の動きが観察されるものを指し、液体状態であるとは、30秒以内に液面が水平になるものを指す。
市販の木綿タオル(武井タオル(株)製 3700番、白色)24枚を、エマルゲン108(花王株式会社製ノニオン型界面活性剤)4.5gを溶解した20℃の水道水45L中で10分間攪拌した後、すすぎ2回、脱水6分を行なった。この界面活性剤溶液中での攪拌から脱水までの工程を2回繰り返し、その後、20℃の水道水45L中で10分攪拌した後、すすぎ2回、脱水6分を行った。この水道水中での攪拌から脱水までの工程を3回繰り返して、布についている糊を除去した。一旦乾燥させた後、20℃水道水中、表2の液体柔軟剤組成物を、組成物中の第四級アンモニウム塩の総量がタオルに対して0.1重量%になる量用い、浴比30L/kg(対タオル重量)で、攪拌下5分間処理した。それらのタオルを25℃、40%RHの恒温恒湿室にて24時間乾燥させた。それぞれのタオルについて、柔軟性及び吸水性の評価を下記の評価基準に基づいて行った。その結果も表2にまとめて示す。
5人の専門パネラーにより上記処理タオルの官能評価を行なった。比較例1の液体柔軟剤組成物で処理したタオルを対照(基準)とし、下記評価基準により、柔軟性を評価した。
+2:対照よりかなり柔らかい
+1:対照よりやや柔らかい
0:対照と同じ
-1:対照の方がやや柔らかい
-2:対照の方がかなり柔らかい
得られた5人のパネラーの評価の平均値を表2に示す。
上記により処理を行い、25℃/40%RHの恒温・恒湿室にて調湿した木綿タオル(武井タオル(株)製 3700番、白色)について、その平織り部分から2.5cm×25cm角の試験布を切り出し、該試験布の下端を25℃の水に浸し、30秒後における水の上昇した高さを測定した。実施例1~9及び比較例2については、15分後にも測定を行なった。実験は3回行い、その平均値を吸水高さ(cm)とした。吸水高さの値が高いほど、処理した布の吸水性が高いことを示している。
