Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
The registered substance is not readily biodegradable and hydrolytically stable at any pH (from 2 to 12). However, the degradation observed strongly suggests that it is totally primarily biodegradable within 28 days.
Therefore, the substance is not considered persistent (P) or potentially very persistent (vP). Moreover, with a BCF value well lower than 2000 L/kg (comprised between 43 and 883 using a weight of evidence approach), the registered substance does not meet the criterion for bioaccumulation (B). For the T criterion, no data are available in chronic conditions. However, the most sensitive species in acute conditions is fish with a predicted 96h-LC50 value greater than 0.1 mg/L (at 1.3 mg/L), therefore the registered substance is presumably not T.In addition, the substance is not classified as carcinogenic (category 1A or 1B), germ cell mutagenic (category 1A or 1B), or toxic for reproduction (category 1A, 1B or 2) according to Regulation EC No 1272/2008 and no other evidence of chronic toxicity was observed, as identified by the classification specific target organ toxicity after repeated exposure (STOT RE Category 1 or 2) according to Regulation EC No 1272/2008.
In conclusion, the registered substance cannot be considered PBT or vPvB.
- Likely routes of exposure:
None
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
