本実施形態の洗浄剤組成物の製造方法は、以下の工程を含む。
(1)実質的に水とt-ブタノールとからなる混合溶媒中、アルカリ性化合物の存在下で5.0~60時間、酸性アミノ酸と脂肪酸クロライドとを縮合反応し、反応液を得る第一工程(以下、「アシル化反応工程」ともいう。)
(2)得られた反応液を、酸でpH1~6とし、35~80℃の温度において有機層と水層とに分層し、N-アシル酸性アミノ酸を含む有機層を取得する第二工程(以下、「酸沈工程」ともいう。)
(3)取得した有機層を、水及び/又はt-ブタノールと混合し、35~80℃の温度において水層とN-アシル酸性アミノ酸とを含む有機層とに分層し、不純物を除去したN-アシル酸性アミノ酸を含む有機層を取得する第三工程(以下、「水洗工程」ともいう。)
(4)取得した有機層から、N-アシル酸性アミノ酸のカルボキシル基量の1/20以上を中和し、有機層の温度が90℃以下の条件で、かつ、蒸留時において水を添加し有機層中の固形分濃度を該有機層の総量(100質量%)に対して5.0~50質量%に維持して、有機溶媒を留去する第四工程(以下、「溶媒留去工程」ともいう。)。
本実施形態のアシル化反応工程は、水とt-ブタノールとの混合溶媒中、アルカリ性化合物の存在下で、酸性アミノ酸と脂肪酸クロライドとを縮合反応する工程であり、該縮合反応(アシル化反応)により、粗N-アシル酸性アミノ酸が生成する。また、縮合反応により得られる反応液を、「アシル化反応液」ともいう。
本実施形態の酸沈工程は、アシル化反応液を、例えば塩酸、硫酸のような酸(好ましくは鉱酸)でpHを1~6とし、有機層と水層との二層に分離し、有機層を取得する工程である。アシル化反応液中では、生成したN-アシル酸性アミノ酸がアルカリ塩の形で存在している。これに酸を加えることで、N-アシル酸性アミノ酸中のカルボキシル基の一部もしくは全部をフリーの酸にすることで、有機層と水層とに分層するものである。酸沈時のpHによって、カルボキシル基の解離状態が変わり、分層状態、即ち有機層と水層との質量比や無機塩類の除去性がやや変わるため、pH1~3で実施することが好ましく、より好ましくはpH1~2.5である。
本実施形態の水洗工程は、酸沈工程で得られた有機層中の水溶性不純物を液液抽出法により水層中に移行させ低減する工程である。具体的には、酸沈工程後の有機層に水及び/またはt-ブタノールを添加してN-アシル酸性アミノ酸/t-ブタノール/水の組成を調整し、液液抽出で有機層中の水溶性不純物、主にアシル化反応工程及び酸沈工程で生成する無機塩類を水層中に移行させることを行う。

本実施形態の洗浄剤組成物を用いることにより、起泡力に優れることのみならず、発生した起泡が長時間持続して安定である。本実施形態の洗浄剤組成物は、所定の条件において、起泡発生から5分後において、起泡発生時の泡の高さから60%以上の高さを維持することが好ましく、80%以上の高さを維持していることがより好ましい。このような性能は、成分(A)と成分(B)とを少なくとも含む洗浄剤組成物で発揮され、成分(A)、成分(B)、及び成分(C)からなる洗浄剤組成物、成分(A)成分(B)、成分(C)、及び成分(D)からなる洗浄剤組成物、成分(A)、成分(B)、成分(C)、及び成分(E)からなる洗浄剤組成物、成分(A)、成分(B)、成分(C)、成分(D)、及び成分(E)からなる洗浄剤組成物のいずれの場合でも発揮される。

(アシル化工程)
L-アスパラギン酸モノナトリウム860g(5.55mol)、純水2978g、水酸化ナトリウム222g(5.55mol)の混合溶液に、80質量%t-ブタノール水溶液1049gを加え、この溶液を3℃に維持しつつ、25質量%水酸化ナトリウムでpHを12に調整しながら塩化ラウロイル1210g(約5.2mol)を撹拌下、滴下した。アシル化工程の時間は32時間であった。
80質量%t-ブタノール水溶液を1136g加えた後、75%硫酸を滴下して、液のpHを2に、また液の温度を45℃に調整し、1.0時間静置して有機層と水槽とに分層した後、有機層を分取した。
分取した有機層に対し有機層と同質量の20質量%t-ブタノール水溶液を添加して攪拌し、45℃で1.0時間静置して有機層と水層とに分層した。
分取した有機層中のN-ラウロイル-L-アスパラギン酸のカルボキシル基の83%が塩の形となるように水酸化ナトリウムを有機層に添加し、さらに固形分含量が25質量%となるように純水を添加した。その後、噴霧式蒸発器を用い、固形分を25質量%に維持するように純水を添加しながら、70℃で20時間減圧蒸留を行い、N-ラウロイル-L-アスパラギン酸ナトリウム塩水溶液を得た(収率98%)。水溶液(洗浄剤組成物)の組成を表1に示す。
酸沈工程の時間を15時間とし、且つ、溶媒留去工程の時間を80時間とした以外は実施例10と同様の条件でN-ラウロイル-L-アスパラギン酸ナトリウム塩水溶液を得た(収率95%)。水溶液(洗浄剤組成物)の組成を表1に示す。
アシル化工程の酸沈工程の時間を15時間とし、且つ、溶媒留去工程の時間を80時間とした以外は実施例10と同様の条件でN-ラウロイル-L-アスパラギン酸ナトリウム塩水溶液を得た(収率95%)。水溶液(洗浄剤組成物)の組成を表1に示す。
実施例12で得られた組成物にラウリン酸の遊離脂肪酸が5質量%となるように添加し水溶液を得た。水溶液(洗浄剤組成物)の組成を表1に示す。
アシル化工程の時間を2.5時間とした以外は実施例7と同様の条件で、N-ココイル-L-グルタミン酸を30質量%含有する水溶液を得た(収率96%)。水溶液(洗浄剤組成物)の組成を表1に示す。
アシル化工程の時間を68時間とした以外は実施例7と同様の条件で、N-ココイル-L-グルタミン酸を30質量%含有する水溶液を得た(収率96%)。水溶液(洗浄剤組成物)の組成を表1に示す。
表2の組成の洗浄剤組成物を調製し、起泡持続性と粘度とを評価した。実施例14~21における洗浄組成物は、脂肪酸t-ブチルエステルを含有しているので、起泡持続性に優れ、粘度も高い傾向となった。一方、比較例4~5における洗浄組成物は、脂肪酸t-ブチルエステルを含有していないので、実施例14~21のそれと比べて、起泡持続性が劣り、粘度も低い傾向となった。
