Justification:

According to ECHA’s guidance[1], the PBT assessment of UVCBs should be conducted on the individual constituents within the UVCB. Therefore, the PBT assessment for this category was conducted by evaluating the individual constituents reported by the registrants. According to the guidance “Constituents, impurities and additives should normally be considered relevant for the PBT/vPvB assessment when they are present in concentration of ≥ 0.1% (w/w).” However, for the sake of proportionality of the efforts required to conduct the PBT assessment and the level of risk being considered, the threshold concentration of ≥ 0.1% (w/w) can be raised for the PBT/vPvB assessment. This will also ensure that there is consistency in the approach used for reporting constituents’ concentrations in the substance identity profile as stipulated in other ECHA guidance.As per the ECHA UVCB guidance, constituents which are CMR and/or PBT above 0.1% and other constituents ≥ 10% areto bereported[2].

The table presented in attached justification documents lists the constituents and their evaluation for each of the PBT criteria. For some constituents, experimental data is available (e.g. benzene, toluene, ethylbenzene, xylenes, naphthalene, styrene, DCPD) for each of the screening criteria. However, for the remaining constituents either the ECHA database was searched for registration dossiers containing the required information to perform the PBT assessment or QSAR (EPIWEB 4.1) were used to arrive at the conclusions presented. The table includes evaluation of all the main criteria of persistence, bioaccumulation and toxicity. However, Annex XIII of the Reach legislation indicates that if there is no indication that the substance is persistent (P) and / or bioaccumulative (B) then no further evaluation of the T property is necessary for the specific purpose of the PBT assessment.

Please refer to the attached justification for the detailed P, B and T analysis table of constituents.
