Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Biodegradation in water: not readily biodegradable (0% biodegradation after 56 d, enhanced study OECD 301 F)

- Bioaccumulation: no potential to bioaccumulate (see WoE for the assessment of bioaccumulation attached in chapter 13 IUCLID)

- Aquatic acute toxicity:

Fish: LC50 (96 h) = 18 mg/L (Oncorhynchus mykiss, OECD 203, nominal)

Aquatic invertebrates: EL50 (48 h) = 1.13 mg/L (Daphnia magna, OECD 202, nominal)

Algae: ErC50 (72 h) >10.0 mg/L (Pseudokirchneriella subcapitata, OECD 201, nominal, read-across to CAS 80939 -62 -4)

- Aquatic chronic toxicity:

Fish: No data available

Aquatic invertebrates: No data available

Algae: NOEC (72 h) = 3.2 mg/L (Pseudokirchneriella subcapitata, OECD 201, nominal, read-across to CAS 80939 -62 -4)

ErC10 (72 h) = 4.9 mg/L (Pseudokirchneriella subcapitata, OECD 201, nominal, read-across to CAS 80939 -62 -4)

Classification justification according to CLP

Based on the data above, the substance is considered to be not rapidly degradable in the environment. The most sensitive organism in the available short-term toxicity test were aquatic invertebrates (EL50 (48 h) = 1.13 mg/L. Chronic toxicity data are only available for algae (NOEC = 3.2 mg/L). Therefore the classification was assessed based on both, the acute toxicity and the chronic toxicity data. The substance was classified according to the most stingent outcome. Thus, the substance has to be classified and labelled as “Aquatic Chronic 2” (H411) according to the consolidated version Regulation (EC) No 1272/2008 (CLP) and considering all further amendments.
