This document specifies a test method by artificial perspiration solution aqueous extraction for the determination of the aqueous extractable content of the following preservative agents in leather by liquid chromatography:<\/p>\n
2-(thiocyanomethylthio)-benzothiazole (TCMTB);<\/p>\n<\/li>\n
4-chloro-3-methylphenol (PCMC);<\/p>\n<\/li>\n
2-phenylphenol (OPP);<\/p>\n<\/li>\n
2-octylisothiazol-3(2H)-one (OIT);<\/p>\n<\/li>\n<\/ol>\n
This method can also be used to determine breakdown products of these preservative agents, which protect leather from microbiological attack.<\/p>\n
