PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB

2-Ethylhexanoic acid, compound with 2-aminoethanol (1:1)  is not deemed to be persistent in the marine environment based on the results from a ready biodegradability test in accordance with the OECD 306 guideline during which ready biodegradability (100%) was achieved at day 28. It is then concluded that the substance is not regarded as fulfilling the criteria for Persistence (P or vP).


The partition coefficient (log Kow) of the registered substance was determined to be below 0 indicating a lack of potential to bioaccumulate. Therefore, the substance does not meet the B or vB criteria.


In accordance with Annexes VII and VIII of REACH, no long-term toxicity study on the registered substance were performed for the purpose of this registration and no data on the long-term toxicity for marine/freshwater organisms was identified. Data on short-term toxicity of the registered substance to fish, aquatic invertebrates, and algae was provided. All L(E)C50 for short-term toxicity were above 1 mg/L and therefore above screening values for T properties described in Table R.11-6 of the Guidance on Information Requirements and Chemical Safety Assessment Chapter R.11: PBT/vPvB assessment (ECHA, 2017).


The toxicity of the substance was investigated in accordance with Annexes VII and VIII of REACH. In accordance with Regulation EC No 1272/2008, it was concluded that 2-Ethylhexanoic acid compound with 2-aminoethanol (1:3) meets the criteria for classification as toxic for reproduction category 1B.

Therefore, the substance meets the T criteria.


2-Ethylhexanoic acid, compound with 2-aminoethanol (1:1) does not meet the PBT and the vPvB criteria. It is not considered relevant to further investigate the PBT or vPvB properties of the substance.
