PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB
Justification:

Preliminary remark


An assessment of PBT and vPvB properties of several Diarylide Pigments (structural analogues of the registration substance) was performed by the TC NES Subgroup on Identification of PBT and vPvB substances. ECB Summary Fact Sheets (SFS) on these evaluations are available at http://ecb.jrc.ec.europa.eu/esis/.


 


The following substances were evaluated:


 


EC no. 225-822-9; CAS no. 5102-83-0; 2,2'[(3,3'-dichloro[1,1'-biphenyl]-4,4'-diyl)bis(azo)]- bis[N-(2,4-dimethylphenyl)-3-oxobutyramide]; CI Pigment Yellow 006


 


EC no. 226-789-3; CAS no. 5468-75-7; 2,2'[(3,3'-dichloro[1,1'-biphenyl]-4,4'-diyl)bis(azo)]- bis[N-(2-methylphenyl)-3-oxobutyramide]; CI Pigment Yellow 14


 


EC no. 226-939-8; CAS no. 5567-15-7; 2,2'[(3,3'-dichloro[1,1'-biphenyl]-4,4'-diyl)bis(azo)]- bis[N-(4-chloro-2,5-dimethoxyphenyl)-3-oxobutyramide; CI Pigment Yellow 83


 


For all three pigments the TC NES Subgroup concluded that “the substance is not considered to be a PBT or a vPvB substance. It does not meet the B (or vB) criterion, or the T criterion. It is considered likely to meet the P (and vP) criterion in order to fulfil its technical specification (it is a pigment).”


 


Overall Conclusion


In agreement with the conclusion of the TC NES Subgroup on Identification of PBT and vPvB substances on three Diarylide Yellow Pigments it is concluded here that all Diarylide Yellow Pigments, including the registration substance


 


- are not ready biodegradable and are considered to fulfil the P criterion


- are not fulfilling the B (or vB) criterion


- and are not fulfilling the T criterion


 


and therefore are evaluated to be not PBT or vPvB substances.

Likely routes of exposure:

The submission substance is not PBT or vPvB. Therefore no emission characterisation is required.
