Description
また、適度な粘着性および凝集性の両立を指向した粘着剤および粘着製剤も知られている(特許文献3)。しかし、かかる粘着剤および粘着製剤においては、皮膚貼付性、すなわち貼付部位における剤の追従性は必ずしも十分ではない。
すなわち、本発明は、(メタ)アクリル酸ヒドロキシエチルを3〜25重量%構成成分とするアクリル系共重合体、可塑剤および擬似架橋性化合物を含む組成物であって、可塑剤の含有量と擬似架橋性化合物の含有量との比が、30:1〜250:1である、前記組成物に関する。
また、本発明は、可塑剤の含有量が、アクリル系共重合体100重量部に対して、30〜200重量部である、前記組成物に関する。
さらに、本発明は、 擬似架橋性化合物の含有量が、アクリル系共重合体100重量部に対して0.3〜10重量部である、前記組成物に関する。
さらに、本発明は、アクリル系共重合体が、(メタ)アクリル酸アルキルエステル、(メタ)アクリル酸ヒドロキシエチルおよびN−ビニル−2−ピロリドンを含む共重合体である、前記粘着剤組成物に関する。
さらに、本発明は、擬似架橋性化合物が、硼酸および/またはその塩、アミン系化合物、アルミン酸塩およびフェノール系化合物からの1種または2種以上である、前記組成物に関する。
また、本発明の組成物のうち、可塑剤の含有量が、アクリル系共重合体100重量部に対して、30〜200重量部であるものにおいては、皮膚刺激性がより少なく、かつより高い凝集力を有するという効果を有する。
また、本発明の組成物のうち、 擬似架橋性化合物の含有量が、アクリル系共重合体100重量部に対して0.3〜10重量部であるものにおいては、擬似架橋性によるより高い凝集力が得られ、かつより好適な架橋による、粘着性の悪化を回避することができるという効果を有する。
また、本発明の組成物のうち、アクリル系共重合体が、(メタ)アクリル酸アルキルエステル、(メタ)アクリル酸ヒドロキシエチルおよびN−ビニル−2−ピロリドンからの1種または2種以上を含むものによれば、粘着力がとくに優れるという効果を有する。
本発明のうち、擬似架橋性化合物が、硼酸および/またはその塩、アミン系化合物、アルミン酸塩およびフェノール系化合物からの1種または2種以上であるものによれば、糊残りの問題がさらに良好に解決された組成物が提供される。
より高い粘着性付与のためには、本発明の組成物におけるアクリル系共重合体は、アルキル基の炭素数が4〜12のアルコールとのエステルからなる(メタ)アクリル酸アルキルエステルを30〜80重量%、好ましくは40〜70重量%含み、例えば(メタ)アクリル酸ブチル、(メタ)アクリル酸イソブチル、アクリル酸ヘキシル、アクリル酸オクチル、(メタ)アクリル酸2−エチルヘキシル、(メタ)アクリル酸イソオクチル、(メタ)アクリル酸ドデシル等が挙げられ、これらは単独で用いてもよいし、併用されてもよい。(メタ)アクリル酸アルキルエステルの含量を30%以上とすることによってより高い粘着性が達成され、また80%以下とすることによって本発明の主旨である擬似架橋による高い凝集力向上が達成される。
前記擬似架橋性化合物の含有量は、多くすると添加による凝集力の増強効果が発現し易くなり、少なくすると粘着力が向上するので、アクリル系共重合体100部に対し0.3〜10部が好ましく、より好ましくは0.5〜5部である。
また、前記可塑剤の含有量と前記擬似架橋性化合物の含有量との比は、30:1〜250:1であり、好ましくは30:1〜200:1であり、より好ましくは30:1〜150:1であり、さらに好ましくは30:1〜120:1である。
硼酸塩の例としては硼酸アンモニウム、硼酸トリエチル、硼酸トリブチル、硼酸イソプロピル、硼酸カリウム、硼酸カルシウム、硼酸バリウム、硼酸マグネシウム、硼酸トリアリル等が挙げられる。硼酸塩は無水物であっても水和物であってもよい。硼酸アンモニウム8水和物がとくに好ましい。硼酸もとくに好ましく用いられる。
アルミン酸塩としては、アルミン酸カリウム、アルミン酸ナトリウム、アルミン酸カルシウムおよびアルミン酸マグネシウムなどが挙げられる。アルミン酸ナトリウムがとくに好ましい。
フェノール系化合物としては、フェノールの他、ピロカテコール、レゾルシノール、ヒドロキノンのようなベンゼンジオールが挙げられる。ベンゼンジオールが好ましく、レゾルシノールがとくに好ましい。

実施例1におけるモノマー組成がアクリル酸2−エチルヘキシル300部、アクリル酸ヒドロキシエチル5部、N−ビニル−2−ピロリドン80部である以外はすべて同様にして固形分30重量%の粘着剤溶液を得た。
実施例1、2、3、比較例1によって得られた粘着剤溶液に、可塑剤、架橋性化合物加えて、液全体をディゾルバーにて均一に攪拌し、混合液を得た。得られた混合液をシリコン処理した厚さ35μmのPETフィルム上に乾燥後の粘着剤層の厚みが100μmになるように塗布し、乾燥させ、次いで厚さ35μmのPETフィルム上に上記粘着剤層をラミネートして皮膚用粘着シートを得た。次いで、作成したシートを幅1cmに切断してテープ状とし、25℃においてベークライト板へ1cm×1cmの接着面積で荷重500gのローラー往復させて密着させた後板を垂直にしてずれ変形距離(3g、2分)とずれ変形距離(80g、5分)とを測定した。
上記により作成した各シートを20cm2に裁断し粘着剤層の重量(W1)を測定した。次にそのシートを酢酸エチル中に浸し3日間放置して溶剤可溶分を抽出した。その後不溶分を取り出し乾燥させた後の粘着層の重量(W2)を測定し、下記の式によってゲル分率を算出した。結果を表4に示す。
(W2×100)/(W1×A/B)
A:(粘着剤+架橋剤)重量、B(粘着剤+可塑剤+架橋剤)重量
(皮膚刺激)
上記により得られた試験シートについて、以下の評価を行い、結果を表5に示した。
成人男子5人の上腕部に各試験シート(20cm2)を貼付し、24時間後に剥離した。剥離して1時間後の皮膚の状態を目視で観察して、下記評価基準により評価し、5人の評点の総和の平均値を指数とした。
(評価基準)
0:紅斑なし、 1:かろうじて識別できる程度のごく軽度の紅斑、 2:明らかな紅斑3:中程度の紅斑、4:深紅色の強い紅斑
貼付性
成人男子5人の上腕部に各経皮吸収製剤を貼付し、24時間後に剥離した。剥離直前の皮膚上のシートの貼付状態を目視で観察して、下記評価基準により評価した。
(評価基準)
○:ほぼ全員完全に貼付、△:1〜3人に部分的剥離あり、×:4〜5人に剥離あり
糊残り性
成人男子5人の上腕部に各経皮吸収製剤を貼付し、24時間後に剥離した。剥離直後の皮膚の状態を目視で観察して、下記評価基準により評価した。
(評価基準)
○:ほぼ全員完全に糊残りなし、△:1〜3人に部分的糊残りあり、×:4〜5人に糊残りあり
実施例4、5、比較例4、5を構成成分とするアクリルアルキルエステル組成物及び皮膚有価物を表6に示す配合とした以外は上記と同様にして医薬品パッチ、化粧品パッチを作成し、評価した。結果を表6に示す。表中、Hはインドメタシンを、Kはケトプロフェンを、EはビタミンEを、それぞれ表わす。
刺激性
日本白色種のウサギの剃毛した背部にテープ剤の試験片(2.5×2.5cm )を貼付し、24時間後、これを剥離し、剥離1時間後の皮膚の紅斑状態を目視で観察した。なお、本試験において浮腫及び痂皮の形成は認められなかった。各製剤は計4匹に貼付した。紅斑の程度は下記の0〜4の5段階の判定基準で評価した。0:紅斑なし、 1:かろうじて識別できるごく軽度の紅斑、 2:明らかな紅斑、3:中程度の紅斑、 4:深紅色の強い紅斑。
各ウサギにおける評点の総和を4で割った平均値を各々のテープ製剤の皮膚刺激指数とした。
上記刺激性の試験と同じ操作で、ウサギの皮膚にテープ製剤を24時間貼付し、剥離直前の貼付性の有無を目視で観察した。評価基準は下記のとおりである。
0:製剤剥離なし1:一部に剥離を認める2:明らかに剥離を認める
平均値(評価点の総和を4で割った値)を各製剤の貼付性指数とした。
