* Note Xylene – commonly xylene (CAS 1330-20-7) has referend to a mixed xylene stream with a significant ethyl benzene content.
Following a request from ECHA, to meet the descriptor a mixed xylene stream needs to contain all three isomers and a maximum concentration of 10% ethylene benzene. If the stream has >10% ethyl benzene then it is likely that the appropriate descriptor for the substance is “Reaction mass of ethylbenzene and xylene”. Please see the LOA substance pages for more information – access is available to Joint Submission Group (JSG) members and registrants.
