Description of key information

According to Regulation (EC) No. 1907/2006, Annex VIII, section 9.2.2.1, column 2, the study need not be conducted if the substance is highly insoluble in water or the substance is readily biodegradable.  The water solubility of the test substance is 47 µg/L at 20 °C and is therefore classed as insoluble.  Furthermore a Ready Biodegradability test shows 54.1% degradation after 28 days.  Although this does not fulfill the minimum criteria set out by the OECD method, it does however indicate that the material achieved >50 % within 30 days, highlighting its propensity for biodegradation. An inherent biodegradability test shows 80.5% degradation after 28 days, therefore it is considered that the material is inherently biodegradable and as such not persistent in environmentally significant conditions.  Therefore given the poor solubility and propensity for biodegradation further studies are scientifically unjustified.
