Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

Classification according directive 2008/1272/EEC (CLP) is performed independently for acute and chronic hazards.

Acute hazard category:

The highest acute aquatic toxicity of three trophic levels was determined for the aquatic invertebrate Daphnia magna with an EC50 (48 h) of 0.27 mg/L. This results in the following acute classification:

Category Acute 1, H400: Very toxic to aquatic life

M-factor: 1

 

Chronic hazard category:

Using available acute data, decisive for a possible chronic classification is failure or fulfilment of rapid degradability and / or presence or absence of a bioaccumulation potential.

Rapid biodegradability according to CLP is given for substances which were assessed as “readily biodegradable” in screening studies (OECD 301). This is not met by the submission substance.

According to the available acute data, most sensitive trophic level are invertebrates with an EC50 (Daphnia magna; 48 h; immobilisation; nominal) of 0.27 mg/L.

This results in the following chronic classification based on acute data:

Category Chronic 1, H410: Very toxic to aquatic life with long lasting effects

M-factor: 1

 

Using available chronic data (algae, invertebrates): The lowest chronic (no) effect concentration of the two trophic levels with chronic data available was determined for the freshwater invertebrate Daphnia magna: a NOEC (21d; reproduction/parental immobilisation; semi-static, TWA) = 0.0013 mg/L (0.0032 mg/L nominal) had been determined.

This results in the following chronic classification, taking into account non-rapid degradability of the submission substance:

Category Chronic 1, H410: Very toxic to aquatic life with long lasting effects

M-factor: 10

 

Chronic classification is to be performed according to the most stringent outcome. Consequently, results based on chronic toxicity data do apply. Final applicable chronic classification:

Category Chronic 1, H410: Very toxic to aquatic life with long lasting effects

M-factor: 10
