This document specifies a test method by acetonitrile solvent extraction for the determination of the total content (solvent extractible) of the following preservative agents in leather by liquid chromatography:
2-(thiocyanomethylthio)-benzothiazole (TCMTB);
4-chloro-3-methylphenol (PCMC);
2-phenylphenol (OPP);
2-octylisothiazol-3(2H)-one (OIT);
This method can also be used to determine breakdown products of these preservative agents, which protect leather from microbiological attack.
