Range of specific surface area:
>= 40 - <= 80 m²/g
Skeletal density:
1.627 g/cm³
Surface treatment applied:
no
PBT status:
the substance is not PBT / vPvB
Justification:

Based on evaluation of the data described in the end point study record in IUCLID section 2.3 it is concluded here that the members of the Quinacridone Pigment Category

·   are not readily 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 neither PBT nor vPvB substances.

 

Overall conclusion:

Based on the assessment described in the subsections below the submission substances of the Category of Quinacridone Pigments are not considered to be PBT /vPvB.

Likely routes of exposure:

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