PBT assessment

PBT assessment: overall result

PBT status:

the substance is not PBT / vPvB

Justification:

Preliminary remark

An assessment of PBT and vPvB properties of several members of the category of Diarylide Pigments 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 of the category members it is concluded here that the members of the Diarylide Yellow Pigment category.

- 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.
