PBT status:

the substance is not PBT / vPvB

Justification:

Based on evaluation of the data described below it is concluded here that Pigment Red 185

·   is not inherently biodegradable and is considered to fulfil the P criterion

·   is not fulfilling the B (or vB) criterion

·   and is not fulfilling the T criterion

and therefore is evaluated to be neither PBT nor vPvB substances.

Overall conclusion:

Based on the assessment described in the subsections below PR 185 is not considered to be PBT /vPvB.

Likely routes of exposure:

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