Abstract
【課題】ガラスまたはプラスチック等の硬質表面の曇りを持続的に防止する曇り止め剤および洗浄剤を提供する。 【解決手段】本発明は、（Ａ）フッ素系両性界面活性剤またはフッ素系アニオン界面活性剤、および（Ｂ）フッ素系ノニオン界面活性剤を含有する曇り止め剤および洗浄剤に関する。また、本発明は前記曇り止め剤または前記洗浄剤を不織布に含浸させたメガネクリーナーに関する。
Description
本発明は、ガラスまたはプラスチック等の硬質表面の曇り止め剤に関する。
メガネレンズ、サングラスレンズ、携帯電話の画面、時計のガラス面、テレビやパソコンのガラス面、鏡などに付着した汚れを除去する方法としては、極細繊維を用いた織布を用いる方法、超音波洗浄、界面活性剤を含む洗浄剤で洗浄する方法などが知られている。なかでも、界面活性剤を含む洗浄剤で洗浄する方法は簡便であって、汚れの再付着の防止や、硬質表面の曇り止めなどの新たな機能を付与することができる。
界面活性剤を含む洗浄剤で洗浄する方法として、特許文献１には、フッ素系界面活性剤と非フッ素系界面活性剤を含有する洗浄剤が開示されている。しかしながら、比較的多量にフッ素系界面活性剤を配合して汚れの再付着を防止することを目的とするものであって、曇り止めについては開示されておらず、また、実際には曇り止め効果が充分なものではなかった。
また、特許文献２では、フッ素系カチオン界面活性剤とフッ素系ノニオン界面活性剤を含有する薬液を含浸させた曇り止めクロスが開示されている。しかしながら、比較的多量にフッ素系界面活性剤を配合する必要があるとともに、曇り止め効果もほとんど持続することができなかった。
本発明は、ガラスまたはプラスチック等の硬質表面の曇りを持続的に防止する曇り止め剤および洗浄剤を提供することを目的とする。
本発明者は、上記課題を解決するため鋭意検討したところ、特定の２種のフッ素系界面活性剤を併用すると、フッ素系界面活性剤の使用量を大きく低減しても、曇り止め効果が長時間持続することを見出し、本発明を完成した。
すなわち、本発明は、（Ａ）フッ素系両性界面活性剤またはフッ素系アニオン界面活性剤、および（Ｂ）フッ素系ノニオン界面活性剤を含有する曇り止め剤に関する。
フッ素系両性界面活性剤またはフッ素系アニオン界面活性剤（Ａ）の濃度が０．１～２０重量％であることが好ましい。

また、本発明は、（Ａ）フッ素系両性界面活性剤またはフッ素系アニオン界面活性剤、および（Ｂ）フッ素系ノニオン界面活性剤を含有する洗浄剤に関する。
また、本発明は、前記曇り止め剤または前記洗浄剤を不織布に含浸させたメガネクリーナーに関する。
本発明の曇り止め剤および洗浄剤は、（Ａ）フッ素系両性界面活性剤またはフッ素系アニオン界面活性剤、および（Ｂ）フッ素系ノニオン界面活性剤を含有するので、均一塗布性を維持したうえで、曇り止め効果を長時間持続することができる。

Ｒｆで表されるフルオロアルキル基またはフルオロアルケニル基の炭素数は、特に限定されないが、好ましくは３～２０であって、直鎖、分岐または環状構造のいずれでもよいが、容易に入手できることから直鎖構造が好ましい。フルオロアルキル基またはフルオロアルケニル基のフッ素の置換数も、特に限定されないが、全ての水素原子がフッ素に置換されたパーフルオロアルキル基またはパーフルオロアルケニル基が好ましい。

フッ素系両性界面活性剤（Ａ）の組成物中の濃度は特に限定されないが、好ましくは３０重量％以下、より好ましくは０．１～２０重量％、さらに好ましくは０．３～１０重量％である。０．１重量％未満では、曇り止め効果が十分に発揮できない虞があり、３０重量％を超えると、経時安定性が損なわれる虞があると共に、コストの面からも好ましくない。
フッ素系アニオン界面活性剤（Ａ）は、界面活性剤中のアルキル鎖中の水素原子をフッ素原子に置換したアニオン界面活性剤である。たとえば、一般式（２）
Ｒｆ－Ｘ－Ｙｂ （２）

本発明の曇り止め剤または洗浄剤は硬質表面に塗布して使用する。硬質表面は特に限定されないが、例えばメガネレンズ、サングラスレンズ、携帯電話の画面、時計のガラス面、テレビやパソコンのガラス面、鏡等が挙げられる。表面にコーティング処理が施され、界面活性剤を均一に塗布し難い硬質表面に適用した場合でも、均一に塗布することができ、曇り止め効果を長時間持続することができる。
本発明の曇り止め剤および洗浄剤は、例えば本発明の曇り止め剤または洗浄用組成物を不織布に含浸させる方法、曇り止め剤および洗浄剤をノズル付き容器、スプレー容器または吸液芯を有するペンタイプ容器等に充填する方法、刷毛で塗り広げる方法等で使用できる。この場合、硬質表面に塗布された曇り止め剤および洗浄剤は、別途乾いた不織布等を用いて塗り広げるように使用されても良い。これらの中でも、携帯性、拭き易さ、汚れのかきとり性などの点で、不織布に含浸させる方法が好ましい。

実施例１～１２および比較例１～７
表１～２に記載した界面活性剤、イソプロピルアルコール、水を表１～２に示した配合量で混合し、曇り止め剤を作製した。
＜曇り止め試験＞
事前に、１４０ｍｌ容積のマヨネーズ瓶に水１００ｇを入れ、５０～５７℃に維持されるように調節された水浴中に置き、マヨネーズ瓶内の水が５０～５７℃に維持された状態にしておく。ワイパー（１１ｃｍ×１１ｃｍ、日本製紙クレシア株式会社製「ケイドライワイパー」）を４つ折りにし、その中心部に得られた曇り止め剤５０μｌを染み込ませ、レンズ（スーパーパワーシールドコート、屈折率１．７６、東海光学株式会社製「ベルーナＺＸ－ＡＳ」）の凸面に対して一定方向に２回やさしく塗り広げるように塗布した。次いで、該レンズを９０度回転させ、上記と同様に曇り止め剤を一定方向に２回やさしく塗布した。このときの均一塗布性を下記基準により評価した。その結果を表１～２に示す。そして、曇り止め剤を塗布したレンズをよく乾かし、凸面が下になるようにして上記マヨネーズ瓶の開口部に載せ、この時を曇り止め試験の開始時間とした。レンズを目視観察し、レンズにおける上記マヨネーズ瓶の開口部に接する部分より中心側の部分のうち、面積にして約半分が曇るまでの時間を曇り止め持続時間として測定した。また、曇り止め効果を下記基準により評価した。その結果を表１～２に示す。

表１より、４種のフッ素系界面活性剤を単独で使用した比較例１～４においては、比較例１および２は活性剤の合計濃度に対する曇り止め効果が明らかに実施例１および２より低く、また比較例３および４はいずれも曇り止め効果が充分ではなかった。また、４種のフッ素系界面活性剤のうち２種を併用した比較例５～７においても、曇り止め効果は充分ではなかった。一方、フッ素系両性界面活性剤またはフッ素系アニオン界面活性剤（Ａ）とフッ素系ノニオン界面活性剤（Ｂ）を組合せると、実施例１および２に示すように、曇り止め持続時間が明らかに長時間持続し、満足できるものとなった。
