Description of key information

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
