Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information:
ASSEMBLY STRUCTURE: homogeneous and solid spheroidal particles.

RIGIDITY: not required/appropriate.
Fraction of constituent particles in the size range 1-100 nm:
>= 50 - ca. 100 %
Structure:
crystalline
Name:
C.I. Pigment Yellow 3
Pure structure:
yes
Range of specific surface area:
>= 5 - <= 125 m²/g
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 submission substance


·   is not readily and 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 a PBT nor a vPvB substance.


 


Overall conclusion:


Based on the assessment described in the subsections below the submission substance 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.
