Additional information

According to column 2 of Annex IX 9.3.2. of REACH Regulation 1907/2006, studies on the accumulation in aquatic species do not need be conducted if the substance has a log Pow of < 3. The log Pow value of C9AS Na (CAS 1072-15-7) is 0.22 and therefore bioaccumulation studies are not required.
