Name:
C.I. Pigment Yellow 111
Type of composition:
legal entity composition of the substance
State / form:
solid: particulate/powder
Related composition:
N-(5-chloro-2-methoxyphenyl)-2-[(2-methoxy-4-nitrophenyl)azo]-3-oxobutyramide
Reference substance:
C.I. Pigment Yellow 111
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 Mono-Azo-Yellow Pigment category

·   are not readily and not inherently 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 Mono-Azo-Yellow 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.
