According to the criteria
set in Annex XI of REGULATION (EC) No 1907/2006 a ready biodegradation
study is scientifically unnecessary based on the following arguments
applied for the Acetolone Pigments. Since it is generally known that
pigments are not or only marginally (bio)degradable, the
Persistance-criterion is accepted for Acetolone pigments.
Therefore only one
biodegradation study was performed. As Acetolone Pigments are of very
poor water solubility, rather inherent than ready biodegradability was
assessed for Pigment Yellow 154 in the Modified MITI Test (II) according
to OECD 302 C. The substance was not inherently biodegradable.
