keystudy showed that DOTE at pH 9, 7 and 4 can be considered
hydrolytically stable. After 5 days at 50 °C less than 10% DOTE was
hydrolyzed (t 0.5 25°C > 1 year).
The bioaccumulation data is available. In the Bouwman, 2010 study
Dioctyltin was found to have (as a worst case) a BCF value of 100. The
worst case BCF value does not meet the criteria for classification as a
bioaccumulative or very bioaccumulative substance as set out by Annex
XII of EC Regulation 1907/2008.
According to Annex XI section 2 of the Regulation EC 1907/2006; testing
for a specific endpoint may be omitted, if it is technically not
possible to conduct the study as a consequence of the properties of the
substance. This is also in accordance with the adaptations stated in
Annex VIII, column 2 section 9.3.1.
In the study by Baltussen (2010), the following statement was included
concerning determining an adsorption coefficient of the test material:
“ The test substance can only be analysed after derivatisation, but
using derivatisation, a distinction between intact test substance and
breakdown products can no longer be made. The test substance cannot be
chromatographed through a liquid chromatography column in its intact
In conclusion, the adsorption coefficient of the test substance could
not be performed according to the OECD 121 method. Since it is not
possible to specifically analyse the intact test substance with any
technique at low levels which is required due to the expected low water
solubility of the test substance, the OECD 106 study is not considered
to be an alternative.”
