Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Study not needing according to Column 2 of REACH annex IX: the chemical safety assessment according to Annex I indicates no need to investigate further the effects on aquatic organisms

Key value for chemical safety assessment

Additional information

According to Annex XI par. 3 and to Column 2 of REACH annex IX the test can be omitted based on the result of the chemical safety assessement.

According to the equilibrium partitioning Fugacity model III, the water % is 11.5% , then the water compartment is not the preferred one for the substance.

The water solubility is really low, under 0.026% and the acute tests indicate toxicity values only for very high concentrations. (100.000 mg/L).

The substance has a water primary biodegradation of less than 2 days and a DT50 in fresh water of 5-7 days. A long term test is not justified because of the biodegradation rate in environmental conditions.

A tier 1 Risk Assessment based on the European main use of the substance elaborated with EUSES 2.0 showed no concern; it is assumed that water exposure will not occur because the exposure scenarios is focused only on industrial application where all waste, when present, is sent to STP, where a 100% of degradation occurs.
