Description of key information

The substance has a low bioaccumulation potential.

Key value for chemical safety assessment

Additional information

In accordance with column 2 of Annex IX 9.3.2 of EC 1907/2006 bioaccumulation testing in aquatic species is not required as the substance has a low potential for bioaccumulation. The test substance will be hydrolysed fast in the relevant pH range and Log Pow values of the hydrolysis products are far below 3. For this hydrolysis products, there exists a determination of the log Pow over a pH range from 4-10 thus showing that the log Pow is very low (-2.38 to - 0.18). For higher pH, the log Pow can also be assumed to be negative due to salt formation. Bioaccumulation is therefore not expected. Additionally, the substance is quickly eliminated from both water body and sediment, with hydrolysis to the free acid and further biodegradation of this hydrolysis product with DT50 values of 0.19 and 1.5 days based on data obtained from soil and water/soil systems from Europe and the U-S and it is not likely that they can be found in the aquatic environment in high concentrations. It can be concluded that the bioaccumulation potential is low and no further test are necessary.
