Key value for chemical safety assessment

Additional information

According to column 2 of Annex IX of the REACH Regulation, studies on the accumulation in aquatic species do not need be conducted if the test item has a log Pow of < 3. The log Pow of C16-18AS Na (CAS 68955-20-4) is – 0.44 and therefore bioaccumulation studies are not required.
