Description of key information

After evaporation or exposure to the air, the product will be rapidly degraded by photochemical processes.

Key value for chemical safety assessment

Half-life in air:
1.018 h

Additional information

Model prediction

Using AOP Program (v1.92) of EPISuite software the aerobic degradation was assessed. The overall OH rate constant was calculated to be 126.0750 E-12 cm3/molecule-sec and the half-life was calculated to be 1.018 h. The substance is presumably not within the applicability domain of the model and the estimated values are highly uncertain. Nevertheless, taking the criteria of the FOCUS air report (2006) into account it was concluded that after evaporation or exposure to the air, the substance will be rapidly degraded by photochemical processes.

 

QSAR-disclaimer

 

In Article 13 of Regulation (EC) No 1907/2006, it is laid down that information on intrinsic properties of substances may be generated by means other than tests, provided that the conditions set out in Annex XI (of the same Regulation) are met. Furthermore according to Article 25 of the same Regulation testing on vertebrate animals shall be undertaken only as a last resort.

 

According to Annex XI of Regulation (EC) No 1907/2006 (Q)SAR results can be used if

(1) the scientific validity of the (Q)SAR model has been established,

(2) the substance falls within the applicability domain of the (Q)SAR model,

(3) the results are adequate for the purpose of classification and labeling and/or risk assessment and

(4) adequate and reliable documentation of the applied method is provided.

 

For the assessment of 2-aminoethyldiethylamine (Q)SAR results were used for aerobic biodegradability in water. The criteria listed in Annex XI of Regulation (EC) No 1907/2006 are considered to be adequately fulfilled and therefore the endpoint(s) sufficiently covered and suitable for risk assessment.

 

Therefore, further experimental studies on aerobic biodegradability in water are not provided.
