発明を実施するための形態
本発明者らは、数多く存在するアニオン界面活性剤の中でも、スルホン酸基が5位以上に存在する炭素数15以上24以下の内部オレフィンスルホン酸塩を含む、炭素数15以上24以下の内部オレフィンスルホン酸塩が、より繊維に吸着しにくいことを見出した。また、前記の内部オレフィンスルホン酸塩に対して、特定のHLBを有するノニオン界面活性剤を併用することで、界面活性剤の繊維への吸着性がより低下することが見出した。界面活性剤の繊維への吸着性がより低下することで、繊維製品を洗浄した後のすすぎがより簡便になることが想定される。
本発明の(A)成分は、スルホン酸基が5位以上に存在する炭素数15以上24以下の内部オレフィンスルホン酸塩を含む、炭素数15以上24以下の内部オレフィンスルホン酸塩であり、繊維に付着した汚れを洗浄する作用を有する。また、洗浄時の繊維製品への吸着性がより低い化合物である。
(A)成分における、内部オレフィンスルホン酸塩の炭素数は、スルホン酸塩が共有結合した内部オレフィンの炭素数を表す。(A)成分における、内部オレフィンスルホン酸塩の炭素数は、繊維製品に付着した汚れの洗浄性がより向上できる観点から、15以上、好ましくは16以上、そして、繊維製品への界面活性剤の吸着量がより低減できる観点から、24以下、好ましくは22以下、より好ましくは20以下、更に好ましくは18以下である。本発明の(A)成分は、炭素数15以上24以下の内部オレフィンスルホン酸塩であり、(A)成分は、スルホン酸基が5位以上に存在する炭素数15以上24以下の内部オレフィンスルホン酸塩を含む。
(a1)成分:スルホン酸基が5位以上に存在する炭素数15以上16以下の内部オレフィンスルホン酸塩を含む、炭素数15以上16以下の内部オレフィンスルホン酸塩
(a2)成分:スルホン酸基が5位以上に存在する炭素数17以上24以下の内部オレフィンスルホン酸塩を含む、炭素数17以上24以下の内部オレフィンスルホン酸塩
(a11)成分:スルホン酸基が5位以上に存在する内部オレフィンスルホン酸塩であって、二重結合が5位以上に存在する炭素数15以上16以下の内部オレフィンを含む内部オレフィンから得られた内部オレフィンスルホン酸塩
(a21)成分:スルホン酸基が5位以上に存在する内部オレフィンスルホン酸塩であって、二重結合が5位以上に存在する炭素数17以上24以下の内部オレフィンを含む内部オレフィンから得られた内部オレフィンスルホン酸塩
この場合、(a11)成分を(a1)成分に、また、(a21)成分を(a2)成分に置き換えて前記の好ましい範囲を適用できる。
かかる内部オレフィンには、二重結合の位置が炭素鎖の1位に存在する、いわゆるアルファオレフィン(以下、α-オレフィンともいう。)を微量に含有するものも含まれる。
また、内部オレフィンをスルホン化すると、定量的にβ-サルトンが生成し、β-サルトンの一部は、γ-サルトン、オレフィンスルホン酸へと変化し、更にこれらは中和・加水分解工程においてヒドロキシアルカンスルホン酸塩と、オレフィンスルホン酸塩へと転換する(例えば、J. Am. Oil Chem. Soc. 69, 39(1992)) 。ここで、得られるヒドロキシアルカンスルホン酸塩のヒドロキシ基は、アルカン鎖の内部にあり、オレフィンスルホン酸塩の二重結合はオレフィン鎖の内部にある。また、得られる生成物は、主にこれらの混合物であり、またその一部には、炭素鎖の末端にヒドロキシ基を有するヒドロキシアルカンスルホン酸塩、又は炭素鎖の末端に二重結合を有するオレフィンスルホン酸塩が微量に含まれる場合もある。
本明細書では、これらの各生成物及びそれらの混合物を総称して内部オレフィンスルホン酸塩((A)成分)という。また、ヒドロキシアルカンスルホン酸塩を内部オレフィンスルホン酸塩のヒドロキシ体(以下、HASともいう。)、オレフィンスルホン酸塩を内部オレフィンスルホン酸塩のオレフィン体(以下、IOSともいう。)という。
なお、(A)成分中の化合物の質量比は、高速液体クロマトグラフィー質量分析計(以下、HPLC-MSと省略)により測定できる。具体的には、(A)成分のHPLC-MSピーク面積から質量比を求めることができる。
本発明者らは、原料となる内部オレフィン中の二重結合の位置が5位以上に存在する内部オレフィン含有量が変わることにより、得られる内部オレフィンスルホン酸塩を含有する洗浄剤組成物の洗浄性が変わることを見出した。
尚、(A)成分中における、スルホン酸基の位置の異なる各化合物の含有量は、HPLC-MSにより測定できる。本明細書におけるスルホン酸基の位置の異なる各化合物の含有量は、(A)成分の全HAS体における、スルホン酸基が各位置にある化合物のHPLC-MSピーク面積に基づく質量比として求めるものとする。ここで、HASは、内部オレフィンスルホン酸のスルホン化により生成する化合物のうち、ヒドロキシアルカンスルホン酸塩、すなわち、内部オレフィンスルホン酸塩のヒドロキシ体である。
これらの化合物のスルホン酸基の位置は、オレフィン鎖又はアルカン鎖における位置である。
中和は、例えばスルホン酸基の理論値に対し1.0~1.5モル倍量の水酸化ナトリウム、アンモニア、2-アミノエタノール等のアルカリ水溶液を反応させることにより行なわれる。加水分解反応は、例えば水の存在下90~200℃で30分~3時間反応を行えばよい。これらの反応は、連続して行うことができる。また反応終了後は、抽出、洗浄等により精製することができる。
なお、内部オレフィンスルホン酸塩(A)を製造するにあたり、炭素数15以上24以下に炭素数の分布を有する原料内部オレフィンを用いてスルホン化、中和、加水分解の処理を行ってもよく、単一の炭素数を有する原料内部オレフィンを用いてスルホン化、中和、加水分解の処理を行ってもよく、また必要に応じて予め製造した異なる炭素数を有する複数種の内部オレフィンスルホン酸塩を混合してもよい。
(B)成分は、HLBが10.5を超え19以下のノニオン界面活性剤である。好ましい(B)成分はポリオキシエチレン基を含みHLBが10.5を超え19以下のノニオン界面活性剤である。本発明に配合される(B)成分のHLBは、洗浄後の界面活性剤の繊維製品への吸着量をより低減できる観点から、好ましくは11以上、より好ましくは12以上、更に好ましくは12.5以上、より更に好ましくは13以上、より更に好ましくは14以上、より更に好ましくは15以上、より更に好ましくは16以上、そして、19以下である。
本発明におけるノニオン界面活性剤のHLBの値は、ノニオン界面活性剤がポリオキシエチレン基を含むノニオン界面活性剤のHLBは、下記式で算出されるHLBを言う。ポリオキシエチレン基の平均分子量とは、オキシエチレン基の付加モル数が分布を有する場合は、平均付加モル数から算出された平均分子量を表す。また(B)成分の平均分子量とは、炭化水素基などの疎水基が分布を有する場合やポリオキシエチレン基の付加モル数が分布を有する場合は、平均値で算出される分子量である。
HLB=〔(ポリオキシエチレン基の平均分子量)/〔(B)成分の平均分子量〕〕×20
尚、以下に具体的なノニオン界面活性剤を例示するが、前記のオキシエチレン基をエチレンオキシ基と称する場合がある。
また、本発明において、ノニオン界面活性剤がポリオキシエチレン基を含まない場合、ノニオン界面活性剤のHLBは、“Journal of Colloid and Interface Science,Vol.107.No.1,September1985”に記載された国枝らの方法に従って測定されたものを言う。この文献には、特定の温度(THLB)とグリフィン(Griffin)によるHLB数とが線形関係にあるという知見に基づくHLBの測定法である。
R1(CO)mO-(A1O)n-R2 (b1)
〔式中、R1は炭素数9以上18以下の脂肪族炭化水素基であり、R2は水素原子又はメチル基であり、COはカルボニル基であり、mは0又は1の数であり、A1O基はエチレンオキシ基及びプロピレンオキシ基から選ばれる1種以上の基であり、nは平均付加モル数であって、6以上50以下の数である。〕

・LCMS装置:(株)島津製作所製 LCMS2020
・溶離液A:10mmol/L 酢酸アンモニウムの蒸留水を用いた水溶液
溶離液B:10mmol/L 酢酸アンモニウムのメタノール溶液

繊維製品への界面活性剤の吸着率を下記の式より求めた。結果を表5に示す。
総界面活性剤の吸着率=100×{(吸着量の測定に使用した2枚の繊維製品に吸着した界面活性剤の総重量)×(洗浄試験1に使用した繊維製品の総重量)/(吸着量の測定に使用した2枚の繊維製品の重量)}/(洗浄液の調製に使用した界面活性剤の総重量量)

洗浄率(%)=100×[(洗浄後の反射率-洗浄前の反射率)/(原布の反射率-洗浄前の反射率)]
表5において、比較例4と実施例を比較すると一般的な洗浄成分であるアルキルベンゼンスルホン酸塩よりも、アニオン界面活性剤として本発明の(A)成分を使用することで、洗浄後の繊維製品に吸着している界面活性剤量が低減していることが分かる。また、(A)成分と(B)成分を併用することで、洗浄後の繊維製品に吸着している界面活性剤量が低減していることが分かる。また、本発明の(A)成分を使用しても、本発明の(B)成分以外の界面活性剤を用いた場合は吸着率が低減していないことが分かる。
表6において、比較配合例1のように(A)成分のみでは、(A)成分の原料オレフィン中の2重結合の位置が5位以上に存在するオレフィンの含有量が変わると洗浄性が変化している。しかしながら、(A)成分と(B)成分を併用した配合例1~6は、(A)成分の原料オレフィン中の2重結合の位置が5位以上に存在するオレフィンの含有量において、洗浄率が変わらない前記含有量の範囲が広くなることが分かる。また、(B)成分の含有比率が高くなることで、(A)成分の原料オレフィン中の2重結合の位置が5位以上に存在するオレフィンの含有量において、洗浄率が変わらない前記含有量の範囲がより広くなることが分かる。
