Leather. Chemical determination of the preservative (TCMTB, PCMC, OPP, OIT) content in leather by liquid chromatography - Artificial perspiration extraction method Ingestion-build-183098 BS EN 342 discusses protective1 Scope 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: 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
