Abstract
Description
本実施例では、70%v/vのイソプロピルアルコール中に含まれる約2%w/vのグルコン酸クロルヘキシジン(7.6の初期見かけpHを有する)の分解速度に対する、消毒液のpHの影響について調査した。
本実施例では、4つの消毒液を用意した。各溶液は、70%v/vのイソプロピルアルコール中に約2%w/vのグルコン酸クロルヘキシジンを含有した。各溶液のpHを、pH低下剤で約4.5に調整した。
本実施例では、70%v/vのイソプロピルアルコール中に2%w/vのグルコン酸クロルヘキシジンを含むバルク消毒液を、pH低下剤でおよそ4.5の見かけpHに調整した。その後に、溶液を別個の画分に分けた。
本実施例では、pH依存性抗菌剤、グルコン酸クロルヘキシジンの微生物有効性に対する、消毒液のpHの影響について調査した。
