Description of key information

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

The substance has an estimated half-life in air of 17.24 hours. As the cut-off time for reaching the stratosphere is 2 days, the substance is considered to have potential / no potential for reaching the stratosphere and/or long-range atmospheric transport.

Key value for chemical safety assessment

Half-life in air:
17.24 h

Additional information

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. 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 2,2'-oxydiethanol (Q)SAR results were used for phototransformation in air (hydroxyl radical reaction).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.
