Description of key information

According to Annex IX section, Column 2 of regulation (EC) 1907/2006 the study does not need to be conducted as the substance is highly insoluble in water. Moreover, TiC is an inorganic substance and biodegradability is an endpoint not applicable to inorganic compounds. Therefore, biodegradation testing of TiC in sediments (REACH endpoint requirement is scientifically unjustified. 

Key value for chemical safety assessment
