Description of key information
Additional information
Source: ECBI/17/97 Rev2:
NL and FR recommended that the substance not be classified due to lack of data.
However, QSAR estimates suggested that the substance should be classified with N; R51-
53. The QSAR proposal was based on the acute toxicity values for fish, daphnia and algae
between 1 and 10 mg/l; logP = 3.5; and not readily biodegradable. UK could agree to
classification with N; R51-53 if the QSARs used were reliable. It was confirmed that the
estimates were reliable as was shown by extensive validation of the used QSAR models.
The QSARs were used conform the recommendations made in chapter 4 on QSARs in the
EU Technical Guidance Document for risk assessment. CEFIC could also agree with this
proposal considering the chemical structure of this entry.
Conclusion: The Group agreed that the substance should be classified with N; R51-53
on the basis of the QSAR estimates.”
