Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In order to determine the classification for hazardous properties related to the aquatic environment, the criteria of the Regulation (EC) No 1272/2008 (CLP) in Annex I were accurately followed. Because no chronic toxicity data is available, adequate acute toxicity data available for all 3 trophic levels was used.
The criteria in Table 4.1.0 (b) (iii) of Annex I of the CLP Regulation were applied.
The toxicity data elements used in assigning the correct classification category are:
Aquatic toxicity data for 3 trophic levels:
Fish (96h) LC50: 3.21 mg/L
Invertebrates (48h) EC50: 12.1 mg/L
Algae (96h) EC50: 5.45 mg/L. No EC10 value has been derived in the algae study.
Environmental fate data:
The Log Kow is 3.01, indicating a low potential for bioaccumulation.
The substance is readily biodegradable.
Based on the acute toxicity data (Table 4.1.0(b) (iii)) the lowest acute toxicity value is between >1 and ≤ 10 mg/L(fish), however, the substance is rapidly biodegradable (and the log Kow < 4).
Therefore, the substance does not need to be classified according to the criteria of the Regulation (EC) No 1272/2008 (CLP) in Annex I.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
