Abstract
The present invention is an antimicrobially-treated material which has a coloring preventing function and is in contact with water or moisture or contains water, comprising (A) a silver-based antimicrobial agent which dissociates silver ions in the water system and (B) a silver ion trapping agent for trapping silver ions comprising one or more kinds of compounds selected from the group consisting of purine bases, pyrimidine bases, thiabendazole, and potassium iodide, wherein a ratio of(A)/(B) is 1/1 to 100/1 by weight.
Claims22
An antimicrobially-treated material which has a coloring preventing function and is in contact with water or moisture or contains water, comprising (A) a silver-based antimicrobial agent which dissociates silver ions in a water system and (B) a silver ion trapping agent for trapping silver ions comprising one or more kinds of compounds selected from the group consisting of purine bases, pyrimidine bases, thiabendazole, and potassium iodide, wherein a ratio of(A)/(B) is 1/1 to 100/1 by weight.
An antimicrobial plastic composition having a coloring preventing function, which comprises (A) a silver-based antimicrobial agent and (B) one or more kinds of compounds selected from the group consisting of purine bases, pyrimidine bases, thiabendazole, and potassium iodide.
An external skin agent having a coloring preventing function, which comprises (A) a silver-based antimicrobial agent and (B) one or more kinds of compounds selected from the group consisting of purine bases, pyrimidine bases, thiabendazole, and potassium iodide.
A sheet-like cosmetic having a coloring preventing function, wherein (A) a silver-based antimicrobial agent and (B) one or more kinds of compounds selected from the group consisting of purine bases, pyrimidine bases, thiabendazole, and potassium iodide are retained in a sheet base with an aqueous medium.
A method of preventing coloring of an antimicrobially-treated material having contact with water or containing water, wherein (A) a silver-based antimicrobial agent which dissociates silver ions in the water system and (B) a silver ion trapping agent comprising one or more kinds of compounds selected from the group consisting of purine bases, pyrimidine bases, thiabendazole, and potassium iodide are mixed at a ratio of (A)/(B)=1 to 100 by weight.
