Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

Classification relevant information

Biodegradation:

·        Not readily biodegradable (22%, based on CO2 evolution) within 28 d (OECD 301 B)

Bioaccumulation:

·        log Kow: 3.39 (OECD 117, HPLC method)

Acute toxicity:

·        to fish: LC50 (96 h) = 10.1 mg/L (measured, geom. mean) for Danio rerio (OECD 203)

·        to aquatic invertebrates: EC50 (48 h) > 1.2 mg/L (mean measured, corresponding to 100 mg/L nominal) for Daphnia magna (OECD 202)

·        to aquatic algae: EC50 (72 h) > 0.68 mg/L (mean measured, corresponding to 100 mg/L nominal) for Desmodesmus subspicatus based on growth rate (OECD 201)

Chronic toxicity:

·        to algae: NOEC (72 h) = 0.21 mg/L (mean measured) for Desmodesmus subspicatus based on growth rate (OECD 201)

 

Classification justification according to CLP

Based on the data above the substance (CAS 72869-86-4) is not rapidly biodegradable. Acute aquatic toxicity data are available for three trophic levels. The lowest acute effect value was determined for fish and amounts 10.1 mg/L (LC50, 96 h). Chronic toxicity data are available only for algae with a NOEC of 0.21 mg/L. Therefore, the substance needs to be classified and labelled as hazardous to the environment Chronic 2 H411 according to the consolidated version of Regulation (EC) No 1272/2008 and further amendments (ATPs).
