Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 478-250-9 | CAS number: -
PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Persistence
The ready biodegradability of the substance was investigated in a study according to OECD Guideline 301 B. The test item proved not to be readily biodegradable. However, at the end of the test the test item showed 54 % degradation indicating that the substance is most probably inherent biodegradable. Therefore, the available data lead to the conclusion that the substance is most probably not regarded as persistant.
Bioaccumulation
Bioaccumulation of the substance can be excluded based on its low logKow of 1.6
Toxicity
The substance is not classified as carcinogenic (Cat.1A or 1B) or toxic for reproduction (Cat.1A, 1B, or 2) according to regulation EC No. 1272/2008 (CLP), nor is there any evidence of chronic toxicity as identified by the classification as Specific Target Organ Toxicity after repeated exposure (STOT RE category 1 or 2) according to the same regulation.
Based on reliable results on short-term toxicity the lowest L(E)C50 for the substance was determined to be 58.9 mg/L (fish).
In accordance with the decision tree depicted in section R11.1.3.3 of ECHA's "Guidance on information requirements and chemical safety assessment", acute toxicity results >0.1 mg/L lead to a screening assignement of "presumably not T".
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.
