A bactericidal disinfectant, an organic mercury compound. It is in the form of lobules or granules, blue-green or greenish-reddish brown, odorless, and soluble in water; its aqueous solution is red and emits yellow-green fluorescence. A 2% aqueous solution is generally called mercurochrome solution, and is commonly known as "red chrome." It is applied to the skin and mucous membranes as a mild disinfectant without irritation. Mercury ions dissociate and exhibit a bactericidal effect, but the bactericidal effect is not very strong. In addition to disinfecting the skin and mucous membranes, it has also been used for disinfecting wounds, washing, and as an eye drop or eye wash. Its advantages are that it is non-irritating and does not corrode metals, but its disadvantage is that it is strongly colored. Because it is a mercury compound, pollution during production has become a problem, and it is no longer manufactured in Japan. The amount used has also drastically decreased. It should be avoided to use it together with tincture of iodine, as it will cause mercury precipitation.

殺菌消毒剤、有機水銀化合物。青緑色ないし帯緑赤褐色の小葉状または粒状で、においはなく、水によく溶け、水溶液は赤色を呈し、黄緑色の蛍光を発する。一般に2%水溶液をマーキュロクロム液といい、俗に「赤チン」とよぶ。刺激性のない緩和な消毒剤として皮膚、粘膜に塗布する。水銀イオンが解離して殺菌作用を現すが、殺菌作用はあまり強くない。皮膚・粘膜の消毒のほか、創面の消毒はもとより、洗浄、点眼・洗眼にも用いられたことがある。刺激性のないこと、金属を腐食しないことが利点であるが、着色が強いのが欠点である。水銀化合物であるので、製造時における公害が問題となり、日本では製造されていない。使用量も激減している。ヨードチンキとの併用は水銀が析出するので避けなければならない。 [幸保文治] [参照項目] |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
