Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Persistence
Not P or vP
Using appropriate methodology (OECD 301 F), the test item has been determined to meet the criteria for ready biodegradation (OECD 301 B) and, in accordance with ECHA Guidance on Information Requirements and Chemical Safety Assessment Chapter R.11: PBT/vPvB assessment (Version 2.0; November 2014) does not fulfil the criteria for ‘persistence’.
Bioaccumulation
Not B
Log Kow of the test substance has been experimentally determined to be 8.66 and the substance is not expected to be bioaccumulative because ECHA Guidance on Information Requirements and Chemical Safety Assessment Chapter R.11: PBT/vPvB assessment (Version 2.0; November 2014) states that, at very high Log Kow (> 6), a decreasing relationship between BCF and Log Kow is observed. This conclusion is underpinned by a calculated BCF of 517.7 L/kg wet weight for the test substance (BCFBAF v.3.01), which is below the level of 2000 L/kg where bioaccumulation becomes a concern. In addition the substance is readily biodegradable and of low water solubility (< 0.0114 mg/L) so no chronic exposure of aquatic organisms is expected.
Toxicity
No conclusion can be reached based on available information
Based on available evidence, and in accordance with Regulation (EC) No. 1272/2008, the substance does not meet the criteria for classification as a carcinogen (category 1A or 1B) or germ cell mutagen (category 1A, 1B or 2). Furthermore there is no evidence of chronic toxicity and the substance does not meet the criteria for classification for specific target organ toxicity (STOT RE 1 or STOT RE 2). With respect to the environment, no toxic effects were reported at saturation in two trophic levels (Daphnia and algae), the substance is not classified as environmentally hazardous when compared to criteria for readily biodegradable substances given in Regulation(EC) No. 1272/2008, and the chemical safety assessment currently raises no concerns.However, present regulatory obligations do not require investigation of long-term exposure to the substance in fish and it is not possible to definitively conclude not T (see ECHA guidance on Information Requirements and Chemical Safety Assessment Chapter R.11: PBT/vPvB assessment (Version 2.0; November 2014).
- Likely routes of exposure:
Human exposure via the dermal route plus release to the environment via waste water.
