Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Aquatic toxicity
Three QSAR predictions are available to assess the aquatic toxicity of the registered substance.
The most sensitive organism appears to be the fish with a predicted 96h-LC50 of 28 mg/L, followed by daphnids with a predicted 48h-EC50 of 60 mg/L. Algae are slightly less sensitive with a 72h-ErC50 of 69 mg/L.
Environmental fate and pathways
According to the key ready biodegradability test, the registered substance is readily biodegradable (74% biodegradation after 28 days, satisfied the 10-day window validation criterion) and therefore is not persistent in the environment. In addition, the registered substance has a log Kow of 2.39, suggesting that it does not have an important affinity for lipids present in organisms, and has consequently a low potential of bioaccumulation. The registered substance is not considered to be bioaccumulative according to CLP (< 4.0) and PBT criteria (< 4.5).
Conclusion on classification
No existing harmonised classification in CLP Regulation Annex VI.
Environmental classification and labelling of a substance is based on data from short-term aquatic toxicity results (and long-term aquatic toxcity results if available), the ready biodegradability of the substance and an experimentally determined BCF (or if absent the measured octanol/water partition coefficient).
Data available :
- lowest L(E)C50 value comprised between 10 and 100 mg/L.
- no data on long-term aquatic toxicity.
- rapidly biodegradable
- no experimental BCF data
- log Kow = 2.4
Based on the above data, the substance is not classified for the environment according to the CLP Regulation 1272/2008/EC
Based on the above data, the substance is Acute cat 3 for the environment according to the GHS regulation
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.
