本発明は、密着性及び伸張性のバランスが向上したゲル組成物及び皮膚外用剤に関する。
[1]アルミニウムイオンを含むゲル組成物であって、
前記ゲル組成物に対して、25℃、線形領域内での歪み条件で動的粘弾性測定(周波数依存性)をおこなったとき、
周波数0.001~100rad/s域に、損失弾性率G'’/貯蔵弾性率G’(tanδ)が1となる周波数が存在し、
25℃、周波数62.8rad/sでの前記ゲル組成物の貯蔵弾性率G’が500Pa以上である、ゲル組成物。
[2]前記[1]に記載のゲル組成物を含む、皮膚外用剤。
本発明のゲル組成物は、アルミニウムイオンを含むゲル組成物であって、前記ゲル組成物に対して、25℃、線形領域内での歪み条件で動的粘弾性測定(周波数依存性)をおこなったとき、周波数0.001~100rad/s域に、損失弾性率G'’/貯蔵弾性率G’(tanδ)が1となる周波数が存在し、25℃、周波数62.8rad/sでの前記ゲル組成物の貯蔵弾性率G’が500Pa以上である。
なお、本発明において、「成分Xを含む」とは、「成分Xが配合されてなる」ことと同義とみなすものとする。
本発明のゲル組成物は、アルミニウムイオンを含有し、周波数0.001~100rad/s域に、損失弾性率G'’/貯蔵弾性率G’(tanδ)が1となる周波数が存在し、25℃、周波数62.8rad/sでの貯蔵弾性率G’が500Pa以上である。
アルミニウムイオンは、イオン相互作用により、架橋ゲルを形成することが可能である。
そして、周波数0.001~100rad/s域に損失弾性率G'’/貯蔵弾性率G’(tanδ)が1となる周波数が存在すると、低周波数側すなわち長時間の動きは粘性的性質がより強く、高周波数側すなわち短時間の動きは弾性的性質がより強いという特異な性質を有するゲル組成物になる。このような性質を有すると、ゲル組成物が適度な柔らかさとなり、伸ばしやすくなり、さらに貯蔵弾性率G’が500Pa以上であると、ゲル組成物が適度な硬さとなり、ゲル組成物が流動し難くなる。
このような特異な性質を有するゲル組成物は、粘性的性質が強いため、本発明のゲル組成物は伸張性が向上すると考えられる。また、対象物に密着しているときはゲル組成物の粘着力に加え適度な弾性率を有するためゲル組成物は流動し難い。これらの性質により、本発明のゲル組成物は密着性が向上すると考えられる。
本発明のゲル組成物は、成分(A)としてポリマーを含有することが好ましい。成分(A)のポリマーはゲル組成物の骨格を形成している。
成分(A)は、例えば、アニオン化ポリマーであり、好ましくはスルホン酸基、硫酸基、カルボキシ基、リン酸基、ホスホン酸基等のアニオン性基を有するアニオン化ポリマーであり、より好ましくはスルホン酸基及びカルボキシ基の少なくとも1つのアニオン性基を有するアニオン化ポリマーであり、更に好ましくはカルボキシ基を有するアニオン化ポリマーである。

成分(A)は、密着性及び伸張性のバランスをより向上させる観点から、好ましくはアニオン化ポリビニルアルコールであり、より好ましくはスルホン酸基及びカルボキシ基の少なくとも1つのアニオン性基を有するポリビニルアルコールであり、更に好ましくはカルボキシ基を有するポリビニルアルコールである。
ここで、本明細書において、アニオン性基とは、アニオン基、又は、イオン化されてアニオン基になり得る基をいう。
