Description
【0001】
【発明の属する技術分野】
本発明は、ポリアルキレンイミン誘導体を含有する洗剤組成物に関する。
【0002】
【従来の技術】
これまで、ポリアルキレンイミン鎖に不飽和カルボン酸が付加したポリマーとしては、特公昭48−20203号公報に、洗剤成分として、ポリエチレンイミンのアミノ基の一部がカルボン酸によってアルキル化されたN−アルキルカルボン酸−エチレンイミンポリマーが開示されているのみである。該公報において開示されているポリマーに用いられているカルボン酸は1種のみであり、2種以上の異なるカルボン酸がポリアルキレンイミン鎖に付加したポリマーについては報告された例はない。
【0003】
【発明が解決しようとする課題】
そこで、本発明は、優れた性能を発揮しうるポリアルキレンイミン誘導体を含有する洗剤組成物を提供することを目的とする。
【0004】
【課題を解決するための手段】
本発明にかかる、ポリアルキレンイミン誘導体を含有する洗剤組成物は、前記ポリアルキレンイミン誘導体が、ポリアルキレンイミン鎖に不飽和カルボン酸であるアクリル酸(塩)とマレイン酸(塩)が付加してなり、前記アクリル酸(塩)とマレイン酸(塩)の比率が、アクリル酸(塩):マレイン酸(塩)=11:89〜97:3(モル比)である、ことを特徴とする。
【0005】
【発明の実施の形態】
本発明のポリアルキレンイミン誘導体は、ポリアルキレンイミン鎖に2種以上の不飽和カルボン酸が付加したものである。
本発明における前記ポリアルキレンイミン鎖としては、例えば、ポリエチレンイミン、ポリプロピレンイミン等のポリアルキレンイミンが挙げられる。これらは1種のみであってもよいし2種以上であってもよい。
前記ポリアルキレンイミンの重量平均分子量は、300〜500,000であることが好ましく、工業的には、500〜300,000であることがより好ましく、1,000〜100,000であることがさらに好ましい。ポリアルキレンイミンの重量平均分子量が大きすぎると、不飽和カルボン酸の反応率が低下する傾向があり、一方、小さすぎると、例えば洗剤組成物等の用途において優れた性能を発現し得ない恐れがある。
【0006】
本発明における前記不飽和カルボン酸としては、例えば、アクリル酸、メタクリル酸、α−ヒドロキシアクリル酸、イタコン酸、マレイン酸、フマル酸、クロトン酸、シトラコン酸およびこれらの塩等が挙げられ、2種以上の不飽和カルボン酸はこれらの中から異なる2種以上を選択すればよい。前記塩としては、ナトリウム塩やカリウム塩等のアルカリ金属塩、マグネシウム塩やカルシウム塩等のアルカリ土類金属塩、アンモニウム塩、エタノールアミンやトリエチルアミン等の有機アミン塩等が挙げられる。なお、2種以上の不飽和カルボン酸のうちの各不飽和カルボン酸の割合は、特に制限されるものではなく、例えば、2種以上の不飽和カルボン酸のなかで最も割合の少ない不飽和カルボン酸が、2種以上の不飽和カルボン酸全量に対して1モル%以上、好ましくは5モル%以上、さらに好ましくは10モル%以上であるのがよい。
【0007】
本発明においては、前記2種以上の不飽和カルボン酸(塩)がアクリル酸(塩)とマレイン酸(塩)であることが、合成のし易さ等の点から好ましい。また、このとき、アクリル酸(塩)とマレイン酸(塩)の比率は、アクリル酸(塩):マレイン酸(塩)=1:99〜99:1(モル比)であることが好ましい。より好ましくはアクリル酸(塩):マレイン酸(塩)=5:95〜95:5(モル比)、さらに好ましくはアクリル酸(塩):マレイン酸(塩)=10:90〜90:10(モル比)であるのがよい。
前記ポリアルキレンイミン鎖に対する前記2種以上の不飽和カルボン酸の合計付加量は、ポリアルキレンイミン鎖中の全窒素原子の1〜80%に不飽和カルボン酸が付加していることが好ましい。より好ましくは、ポリアルキレンイミン鎖中の全窒素原子の5〜70%に不飽和カルボン酸が付加しているのがよく、さらに好ましくは、ポリアルキレンイミン鎖中の全窒素原子の10〜60%に不飽和カルボン酸が付加しているのがよい。2種以上の不飽和カルボン酸の合計付加量が多すぎると、残存する不飽和カルボン酸の量が多くなる傾向があり、一方、少なすぎると、例えば洗剤組成物等の用途において優れた性能を発現し得ない恐れがある。
【0008】
本発明のポリアルキレンイミン誘導体においては、付加した前記不飽和カルボン酸の一部もしくは全部が中和されてカルボン酸塩の形になっていてもよい。中和されている場合の塩としては、前述の不飽和カルボン酸塩と同様のものが挙げられる。
本発明のポリアルキレンイミン誘導体の製造方法は、ポリアルキレンイミンと2種以上の不飽和カルボン酸とを反応させるものである。具体的には、前記ポリアルキレンイミンに前記2種以上の不飽和カルボン酸をマイケル付加させればよい。なお、マイケル付加反応において用いる前記ポリアルキレンイミンと前記不飽和カルボン酸との使用割合は、得られるポリアルキレンイミン誘導体のポリアルキレンイミン鎖に対する2種以上の不飽和カルボン酸の合計付加量が前記範囲になるように、適宜設定すればよい。
【0009】
前記ポリアルキレンイミンに前記不飽和カルボン酸をマイケル付加させる際の付加方法としては、特に制限はないが、溶液反応が好ましく、この場合、攪拌下、静置下のいずれでもよい。
前記溶液反応の際の溶媒は、水系溶媒が好ましく、さらに好ましくは水であるのがよい。また、水系溶媒以外の溶媒を10重量%以下の範囲で適宜加えてもよい。水系溶媒としては、具体的には、メタノール、エタノール、イソプロピルアルコールなどの低級アルコール;ジメチルホルムアミド等のアミド類;ジエチルエーテル、ジオキサン等のエーテル類;等から1種または2種以上を適宜選択して用いることができる。
【0010】
前記溶液反応を行う際の原料濃度は、特に限定されないが、反応時間の短縮化という観点からは、前記ポリアルキレンイミンと不飽和カルボン酸との合計量が、10〜90重量%となるようにすることが好ましく、20〜80重量%となるようにすることがより好ましく、30〜70重量%となるようにすることがさらに好ましい。
前記溶液反応を行う際の反応溶液のpHは、特に限定されないが、マイケル付加反応では一般的にpHが高い方が反応性がよいので、原料の溶解性にもよるが、好ましくは7以上、より好ましくは8以上、さらに好ましくは10以上とするのがよい。pHの調整は、例えば、水酸化ナトリウムや水酸化カリウム等のアルカリ金属水酸化物、水酸化マグネシウムや水酸化カルシウム等のアルカリ土類金属水酸化物、アンモニア、エタノールアミンやトリエチルアミン等の有機アミン等で行うのが好ましく、アルカリ金属水酸化物を用いるのが特に好ましい。
【0011】
前記ポリアルキレンイミンに前記不飽和カルボン酸をマイケル付加させる際には、前記ポリアルキレンイミンと前記2種以上の不飽和カルボン酸とを全て一括仕込みしてもよいし、いずれかを初期仕込みして残りを滴下するようにしてもよいし、全てを滴下してもよい。好ましくは、ジカルボン酸等の反応性が比較的低い不飽和カルボン酸を用いる場合には、これらは初期仕込みしておくのがよい。前記ポリアルキレンイミンに前記不飽和カルボン酸をマイケル付加させる際には、触媒は基本的に不要であるが、必要に応じて反応に悪影響を及ぼさないものであれば適宜使用してもよい。
【0012】
前記ポリアルキレンイミンに前記不飽和カルボン酸をマイケル付加させる際には、重合禁止剤を用いてもよい。特に、重合性の高い不飽和カルボン酸を用いる場合には、重合禁止剤を用いることが好ましい。重合禁止剤としては、例えば、ヒドロキノン、メトキノン、フェノチアジン等が挙げられる。

The results are shown in Table 1. For comparison, the same evaluation was performed for the case where no detergent builder (polyethyleneimine derivative) was used.
<Recontamination prevention capability>
A detergent aqueous solution containing 17.5 ppm of detergent builder (polyethyleneimine derivative) in terms of active ingredient was prepared with the following detergent formulation so that the surfactant (SFT-70H, Neoperex F-25) concentration was 350 ppm.
(Contains detergent)
Nonionic surfactant (SFT-70H) Note 1): 10g
Anionic surfactant (Neopelex F-25) Note 2): 40 g (10 g of active ingredient)
Diethanolamine: 2.5g
Ethanol: 2.5g
Propylene glycol: 2.5g
Water: 42.5g
Note 1) SFT-70H: Polyoxyethylene alkyl ether “Softanol 70H” manufactured by Nippon Shokubai Note 2) Neoperex F-25: Sodium dodecylbenzenesulfonate “Neoperex F-25” manufactured by Kao Next, cotton (JIS-L0803) Eight white cloths prepared by cutting cotton cloth (gold width 3) into 5 cm × 5 cm were prepared. Then, 0.5 g of clay (11 kinds of test dust (Kanto loam, ultrafine) Japan Powder Industry Technical Association) and 8 white cloths are added to 1 L of the detergent aqueous solution, and the washing time is 10 minutes using a tartometer ( Washing and rinsing were repeated three times with a tartometer (100 rpm) and a rinsing time of 2 minutes (tartometer 100 rpm), and then the cloth was dried with an iron. The hardness of the water used was 50 ppm (calcium carbonate equivalent), and the water temperature was 25 ° C.

The reflectance (hunter whiteness) of the white cloth (raw cloth) before the test and the white cloth (contaminated cloth) after the test was measured with a color difference meter (“SE2000” manufactured by Nippon Denshoku Industries Co., Ltd.). The average value of 8 pieces of each cloth was calculated, and the recontamination prevention rate was determined by the following formula using the average value, and the recontamination prevention ability was evaluated.
Recontamination prevention rate (%) = (reflectance of contaminated cloth / reflectance of raw cloth) × 100
