EC number: 203-312-7
CAS number: 105-59-9
After evaporation or exposure to the air, the product will be rapidly degraded by photochemical processes.
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.
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.
the assessment of the 2,2'-methyliminodiethanol
(CAS 105 -59 -9) (Q)SAR
results were used for phototransformation in air.
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.

The photodegradation was calculated for
2,2'-methyliminodiethanol (CAS 105 -59 -9). Based on an
estimated OH radical rate constant of 96.9546E-12 cm³/molecule-sec the
half-life of the compound was calculated to be 3.97 h (test conditions:
sensitiser for indirect photolysis: OH; 0.5 E06 OH/cm³, 24-h day). The
substance was within the applicability domain of the model; however, as
the substance is a tertiary amine, the estimate may be highly uncertain
(AOPWIN v1.92, EPISuite v4.11, BASF SE, 2017). Therefore, after
evaporation or exposure to the air, the product will be rapidly degraded
by photochemical processes.
