Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The following key information was used for the environmental classication:
Lowest acute E(L)C50 value 0.32 mg/L to algae (Handley et al., 1994)
Chronic NOEC value 63 µg/L to algae (Handley et al., 1994)
No other chronic NOEC values available
Ready biodegradable with failing 10d window in an OECD 301B test (Handley and Mead, 1993)
Log Kow: <-1.4 (Brekelmans, 2013)
GHS:
Acute: As the lowest EC50 value (to algae) was <1 mg/L, the substance is classified as Acute 1, H400
Chronic:
Based on chronic data: As the chronic NOEC to algae was ≤ 0.1 mg/L and the substance is not rapidly biodegradable (because of failing 10 -d window criterium, see CLP Annex I, paragraph 4.1.2.9.5 (a), the substance has to be classified in the Category Chronic 1 with H410.
Based on acute data: As the lowest EC50 value (to algae) was < 1 mg/L and the substance is not rapidly biodegradable (see above), the substance has to be classified in the Category Chronic 1 with H410.
From both evaluations (based on available chronic and acute data) it is concluded that the substance has to be classified in the Category Chronic 1 with H410.
DSD:
As the lowest EC50 value (to algae) was <1 mg/L, and the substance is not ready biodegradable (failing 10d-window, see 67/548/EEC, Annex IV, paragraph 5.2.1.3 (a)) the substance has to be classified as N, R50/53.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
