EC number: 229-722-6
CAS number: 6683-19-8
No experimental data on hydrolysis is
available. However, the substance has ester bonds which could be subject
to slow hydrolysis.
estimations of hydrolysis (HYDROWIN v 2.0) show very slow DT50’s,
greater than 2 years and greater than70 days at pH 7 and 8, respectively.
potential degradation products are “Metilox acid” (CAS 20170-32-5), and
pentaerythritol (CAS 115-77-5) (PBT-Assessment
No. 77 for the test substance by the European Commission Joint Research
Considering the high adsorption potential
and the low water solubility, the extend of hydrolysis is expected to be
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 CAS 6683-19-8 (Q)SAR results were used for hydrolysis.
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.
further experimental studies on hydrolysis are not provided.
