Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

PBT assessment: overall result

2-[[(butylamino)carbonyl]oxy]ethyl acrylate
Type of composition:
legal entity composition of the substance
State / form:
Reference substance:
2-[[(butylamino)carbonyl]oxy]ethyl acrylate
PBT status:
the substance is not PBT / vPvB

The PBT assessment of the substance is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2017).


Persistency assessment

One OECD 301 screening study is available investigating the ready biodegradability of the substance. After 28 d the substance reached a degradation of 15%. Thus, the substance does not fulfill the criteria for ready biodegradability and is therefore considered to be potentially P/vP.



The substance has an estimated log Kow of 1.82 ((Q)SAR, EPISuite v4.11, KOWWIN v1.68). Therefore, the substance does not qualify as vB/B, based on the screening criterion (log Pow > 4.5).



The available effect concentration for long-term toxicity to aquatic organisms is ≥ 0.01 mg/L and the effect concentrations for short-term toxicity to aquatic invertebrates are > 0.1 mg/L. Therefore, the substance does not meet the criteria set out in Annex XIII of Regulation (EC) No. 1907/2006 and it is concluded that the substance is not T.


In conclusion, the substance is not PBT/vPvB.
