PBT assessment
Administrative data
PBT assessment: overall result
- Name:
- 2-dibutylaminoethanol - LE
- Type of composition:
- legal entity composition of the substance
- State / form:
- liquid
- >= 98 - <= 100 % (w/w)
- Reference substance:
- 2-dibutylaminoethanol - LE
- Reference substance:
- 2-dibutylaminoethanol - LE
- This impurity is considered relevant for the classification and labelling of the substance
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Based on OECD 301 B tests, the substance is readily biodegradable (according to OECD criteria; BASF SE 2012, report no. 29G0286/05G008; BASF SE 2019, report no. 22G0286/05G024, 22G0286/05G025). Therefore, the substance is not persistent (not P and not vP).
The log Kow (1.86, measured, BASF AG 1993, report no. 93P00886.07) as well as a study according to OECD 305 C (BCF: < 39 L/kg at a concentration of 0.02 mg/L, NITE 2001, report no. A010219) indicate no potential for bioaccumulation, supported by the QSAR models BCFBAF v3.01 and OASIS Catalogic v5.13.1 (calculated BCF values range between 3.7 L/kg and 33.6 L/kg, BASF SE 2017). Therefore, the substance is concluded to be not bioaccumulative (not B and not vB).
The substance is not toxic (not T) since the lowest EC10 is > 0.01 mg/L (algae, 72h-NOErC = 3.2 mg/L, NITE 2004) and it holds no relevant classification.
In conclusion, the substance is considered to be not PBT / not vPvB.
