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.
