Abstract
Description
また、本発明による歯牙付着用パッチは、韓国登録特許第10−0816250号、米国登録特許第6,689,344号、第6,682,721号、第6,780,401号などに記載の方法によって製造できる。
支持層に含まれる高分子のうち、水不溶性高分子とHPMCとを混合して用いる場合、水不溶性高分子のみを用いる場合よりも、ブラッシングによる除去が容易となる。また、他の水溶性高分子を用いる場合に比べ、よい小さい粒度に分解される。本発明の一実施例で、250gの荷重で1分あたり往復90回の速度で3分間ブラッシングして蒸溜水で洗浄しながら洗浄液を集めて確認した結果、網目の大きさが500μmであるメッシュで濾した後、残余物を乾燥して確認した重さが全体重さに対して5重量%未満に過ぎず、望ましくは4.5重量%、より望ましくは4重量%未満に過ぎない。

下記の表1の組成を有する比較例の歯牙美白用パッチ、及び下記の表2の組成を有する実施例の歯牙美白用パッチを製造した。韓国登録特許第10−0816250号における製造例1のbacking層及びreservoir層の製造方法によって製造した。
使用中に溶けて消える比較例2を除き、使用後の除去過程が必要な比較例 1及び実施例1〜6を対象として除去の便宜性についてのアンケートを行った。30名の回答者は、比較例1及び実施例1〜6の各パッチをグループによって 15分ずつ付着させた後、比較例1または実施例1〜6を歯磨きによって除去した。それから、各グループは、製品を替えて使った後、除去の容易性についてのアンケートに回答した。
− アンケート回答基準 −
5:除去が非常に便利であり、歯ブラシに絡みつかない。
4:除去が便利であるが、歯ブラシに残余物が少し残る。
3:除去が便利でなく、歯ブラシに残余物が残って不便だ。
2:除去が不便であり、歯ブラシに残余物が多い。
1:除去が非常に不便であり、歯ブラシに残余物が非常に多い。
比較例1及び実施例1〜6を2セット準備し、一つのセットは各々蒸溜水で30分間振って(shaking)支持層のみを残した後に乾燥して重さを測定し、他の一つのセットは、スライドガラス(slide glass)に付着させた後、37℃、85%の湿度環境で30分間保持した後、ブラッシング機(brushing machine)を用いて250gの荷重で1分あたり往復90回の速度で3分間ブラシングした。その後、スライドガラス、ブラッシングチャンバー(brushing chamber)と歯ブラシを取り外し、蒸溜水で洗浄しながら洗浄液を集めた。このようにして集めた洗浄液を網目1mmのメッシュで濾した後、残余物を乾燥して重さを計り、支持層の全体重さに対する残余物の割合を求めた。
下記の表5の組成を有する比較例の歯牙美白用パッチ、及び下記の表5及び表6の組成を有する実施例の歯牙美白用パッチを製造した。
比較例3及び実施例7〜11を対象として除去の便宜性についてのアンケートを行った。30名の回答者は、比較例3及び実施例7〜11の各パッチをグループによって30分ずつ付着させた後、比較例3または実施例7〜11を歯磨きによって除去した。それから、各グループは、製品を替えて使った後、除去の容易性についてのアンケートに回答した。
