Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Aquatic toxicity

Two valid acute experimental studies based on international guidelines (and GLP) and two QSAR predictions are available to assess the aquatic toxicity of the registered substance. Among all data available, a toxic effect was observed for all aquatic organisms: the 48h-EC50 for Daphnia magna , the 72h-EC50 for algae and the 30-180min EC50 for microorganisms were 35 mg/L(experimental study), 79 mg/L (experimental study) and 45 mg/L (QSAR), respectively. The highest toxicity was observed for fishes with a LC50 (96hrs) of 5.9 mg/L predicted with QSAR.

According to the available data, the lowest LC50 for fishes is in the range 1 - 10 mg/L and therefore does not meet the screening criterion for T.

Environmental fate and pathways

The registered substance is not readily biodegradable and therefore can be considered as a potential persistent susbtance. In addition, with a logKow of 2.4, the substance is not considered as bioaccumulable. Finally,the registered substance is highly mobile in soils with an adsorption coefficient estimated at 140 L/Kg (log Koc = 2.13).

Conclusion on classification

No harmonised classification is available.

Environmental classification and labelling of a substance is generally based on data from short-term aquatic toxicity results, the ready biodegradability of the substance and an experimentally determined BCF (or if absent the measured octanol/water partition coefficient).

Data available:

- lowest L(E)C50 value comprised between 1 and 10 mg/L;

- not rapidly degradable;

- log Kow=2.2

Based on the above data, the substance is classified as Aquatic Chronic 2 according to the CLP Regulation 1272/2008/EC & adaptation 286/2011/EC.
