Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Environmental fate and pathways:

The substance is not considered readily biodegradable (43% biodegradation after 28 days) and based on the hydrolysis study, is stable with a half-life at 179 days at pH 7. The adsorptioncoefficient (Koc) of the substance was estimated, based on a weight of evidence approach using experimental and QSAR results, at 624 L/kg, corresponding to a log Koc at 2.80.This result indicates that the mobility class in soil is low (according to P.J. McCall et al., 1980).

Ecotoxicological information:

Acute valid data, based on international guidelines, are available for three trophic levels: Algae, Aquatic Invertebrates and Fish; and on Microorganisms.

Among data available, the fish, Brachydanio rerio, is the most sensitive species with a 96h-LC50 at 13.1 mg/L. For aquatic invertebrates, the 48h-EC50 was determined at 15 mg/L. For algae, the 72h-EC50 value was determined at 20 mg/L (based on growth rate). For microorganisms, the 3h-EC50 and 3h-NOEC values were determined at 700 mg/L and 180 mg/L respectively.

Conclusion on classification

No harmonised classification is determined for the substance.

Based on data available, the lowest EC50 is comprised between 10 and 100 mg/L (96h-LC50 = 13.1 mg/L, Brachydanio rerio) and the substance is not considered readily biodegradable with a log Kow at 3.92.

Classification according to the Annex VI of the Directive 67/548/EEC: The substance is classified as R52/53 for the environment.

Classification according to the Annex VI of the Regulation (EC) No 1272/2008 (CLP): According to the 2nd ATP, the substance is classified as Aquatic Chronic 3 for the environment.
