No determination was performed according to Method C7 Abiotic
Degradation, Hydrolysis as a Function of pH of Commission Regulation
(EC) No 440/2008 of 30 May 2008, for the following reason:
• During preliminary investigations for the water solubility test
it was concluded that the test item hydrolysed fully within 30 minutes
of contact with water. Substances which hydrolyse rapidly in contact
with water are not suitable for determination using Method C7.
In accordance with 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.
In the water solubility test, the insoluble test item sat at the
sides of the flask and quickly changed from an almost colourless liquid
to a greasy white precipate. The test item therefore hydrolyses
immediately on contact with water to an insoluble solid. all dibutyltin
compounds degrade into dibutyltin and the appropriate ligand, the white
solid observed in the test is probably DBTO, which is known to be
Based on read-across from the structurally similar compound, DBT
maleate, it can be concluded that DBT methyl maleate is not readily
biodegradable. Simulation tests are not available. In the absence of
such information DBT methyl maleate is concluded to be stable to
