Description of key information

The substance will not evaporate into the atmosphere from the water surface.

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
0.001
at the temperature of:
25 °C

Additional information

The Henrys Law constant was calculated using US EPA EPISuite software. The Henrys Law constant was calculated to be 0.000891 Pa*m3 / mol at 25 °C. The substance is not within the applicability domain of the model. Thus, the result may be less accurate.

 

Based on the criteria of OECD TG 23 as the Henrys Law constant is below 100 Pa*m3/mol the substance was considered not to evaporate into the atmosphere from the water surface.

 

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 Henrys Law Constant (HLC) 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 Henrys Law Constant (HLC)are not provided.
