PBT status:

the substance is not PBT / vPvB

Justification:

Assessment of PBT and vPvB properties of the substance was difficult because of the substance properties. The substance is a UVCB substance containing constituents with different kinds of physical-chemical properties. Therefore, there were many difficulties related to the assessment:

-application of PBT and vPvB criteria was not straightforward

-testing of BCF was not technically feasible for the substance

-there were uncertainties related to the testing of Kow properties and biodegradation

-acute aquatic toxicity was tested with WAF.

Due to these difficulties, there are uncertainties related to the assessment. All available data on the substance was taken into consideration in the assessment (instead of applying only specific criteria defined in REACH Annex XIII).

Conclusion on P not vP:

Based on the available data, the substance might be determined as persistent (P) or very persistent (vP). According to ready biodegradability screening test, the substance was not readily biodegradable. It should be noted that interpretation of test results is not straightforward due to the substance properties. The half-life estimated for hydrolytically stable substance is less than a few months.

According to the biodegradation potential of the components in the substance, this substance contains both biodegradable and non-biodegradable constituents. These results also show potential for persistence properties. Based on the available data, this substance is proposed to be considered as persistent (P).

Conclusion on not B vB:

Bioconcentration factors and bioaccumulation factors were estimated with the BCFBAF v3.01 model. The estimated log BCF value for the registered substance was 56. In conclusion, as the estimated BCF values are less than B or vB criteria.

Conclusions on T:

This UVCB substance does not meet the criteria for classification for carcinogenic, mutagenic or toxic to reproduction. Furthermore, there is no other evidence of chronic toxicity. The substance does not meet the criteria for classification for target organ toxicity after repeated exposure (STOT-RE). Therefore, the target substance does not meet the toxicity criterion (T).
