Abstract
Description
まず、水溶性分子として塩化リゾチームを用い、本実施形態に係る水溶性分子複合体の調製を行った。
本試験では、塩化リゾチームの活性の経時変化を、本実施形態に係る水溶性分子複合体とした場合としていない場合とで比較することにより、経時的な活性低下が少ないほど立体構造が保持されているものとして、立体構造保持状態の確認試験を行った。
本品1g中のリゾチームの量[mg(力価)]
=MS/(MT×10) × ( Ab+Ax−At ) / (Ab−As)
MS:乾燥物に換算したリゾチーム標準品の秤取量(mg)
MT:本品の秤取量(g)
本試験では、多価アルコールが配合された本実施形態に係る水溶性分子複合体と、多価アルコールを配合していない比較用の製剤とについて抗炎症効果を検討することで、多価アルコールの有無による効果の違いについて確認を行った。
まず、水溶性分子としてプラセンタを用い、本実施形態に係る水溶性分子複合体の調製を行った。
肌への保湿効果を有するヒアルロン酸ナトリウム、アセチルヒアルロン酸ナトリウムおよび加水分解ヒアルロン酸を混合した混合液を、〔4.各種水溶性分子を用いた水溶性分子複合体含有油剤の調製〕により調製した場合には、水溶性分子複合体含有油剤としない通常のヒアルロン酸混合液と比較して、肌に塗布した場合の保湿感が向上することが示された。
Claims (5)
- 両親媒性分子により構成される親水部会合構造内に存在させた水溶性分子の水溶液を脱水させるにあたり、予め前記水溶液に多価アルコールを添加しておくことで前記水溶性分子の立体配座を維持した水溶性分子複合体。
- 前記水溶性分子が塩化リゾチームであることを特徴とする請求項1に記載の水溶性分子複合体。
- 前記多価アルコールがポリエチレングリコールであることを特徴とする請求項1又は請求項2に記載の水溶性分子複合体。
- 請求項1〜3いずれか1項に記載の水溶性分子複合体が油中に分散してなる水溶性分子複合体含有油剤。
- 請求項4に記載の水溶性分子複合体含有油剤を両親媒性分子を含んだ水溶液に分散させた分散液。
