(isopropylbiphenyl, MIPB), PBT properties according to Annex XIII of
Regulation (EU) 1907/2006 (REACH) were evaluated examining the substance
itself. Assessment was carried out based on ECHA document "Guidance on
information requirements and chemical safety assessment, Chapter R.11:
of two isomers 3- (meta, m-) and 4- (para, p-)isopropylbiphenyl.
Properties and behaviour in the environment of the two isomers are so
similar, that these constituents of isopropybiphenyl are assessed
together as the substance (1-methylethyl)-1,1'-biphenyl (mixture of
criteria for P, and T properties proved to be not fulfilled. With
respect to its bioaccumulation potential (BCF of 2896), the B- criterion
was fulfilled but not the vB criterion. Overall, the substance
