Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The PNEC values were determined for the substance itself by application of methods provided in ECHA Guidance Chapter R.10 (May 2008).
Conclusion on classification
The substance is an organic mono constituent substance. It is moderately soluble in water (1205 mg/L at 20°C) according to standard methods.
The following short-term toxicity are available for the substance:
Fish Acute: 96h-LC50 = 52 mg/L
Aquatic invertebrates: 48h-EC50 = 86.5 mg/L
Algae: 72h-ErC50 = 63 mg/L
The lowest acute aquatic toxicity values based on available data ranges between 10 and 100 mg/L. The long-term toxicity of registered substance to aquatic organisms was not investigated. Thus, there are no adequate chronic toxicity data available.
The degradation of the substance was investigated according to OECD Guideline.
A reliable study carried out according to OECD Guideline 301D and GLP compliant is available on the registered substance. Under the conditions of this study, the registered substance was found readily biodegradable. Therefore, the substance is considered as rapidly degradable in aquatic system.
Information on bioaccumulation potential.
No fish BCF is available. Log Kow is 2.91 (HPLC method), which indicates low potential for bioaccumulation.
CLP Classification proposal
It is proposed to compare submission substance dataset to CLP environmental criteria laid down in CLP Regulation (including 2nd Adaptation to Technical Progress, Com Reg No 286/2011).
Acute aquatic hazard: not classified.
Reasoning: lowest E(L) C50 higher than 1 mg/L.
Chronic aquatic hazard: not classified.
Reasoning: adequate chronic toxicity data are not available, lowest acute E(L) C50 value range between 10 and 100 mg/L, rapidly degradable substance with log Kow < 4.
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).
