Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Hazard assessment conclusion:
PNEC soil
PNEC value:
0.015 mg/kg soil dw
Extrapolation method:
equilibrium partitioning method

Hazard for predators

Secondary poisoning

Hazard assessment conclusion:
no potential for bioaccumulation

Additional information

The PNEC for waste-water treatement is 10 mg/L based on the EC10 value obtained in a pseudomonas multiplication test and an assesment factor of 1.

PNECs for aqueous environment were derived by the assessment method based on chronic aquatic toxicity data. PNECs for sediment and soil were derived therefrom by applying the partitioning method.

The substance has a low potential for bioaccumulation and this hazards for predators via the food chain are not anticipated.

Conclusion on classification

A NOEC value of 0.42 mg/L was obtained in a long term toxicity study to aquatic invertebrate for the substance.

The lowest aquatic acute toxicity being between 1 and 10 mg/L for both substances and as they are considered to be rapidly degradable, UN GHS Chronic Category 3 is applicable.
