Additional information

According to column 2 of Annex IX 9.2.1.2/9.2.1.4 of the REACH Regulation EC 1907/2006, studies on the biodegradation in water and sediment do not need to be conducted if the substance is readily biodegradable. Since C9AS Na (CAS 1072-15-7) was proven to be readily biodegradable, no further biodegradation testing was performed.
