Description of key information

Waived:  The 2-ethylhexanoate component of the tin bis(2 -ethylhexanoate) salt is readily biodegradable.

Key value for chemical safety assessment

Additional information

The tin bis(2 -ethylhexanoate) substance is known to dissociate into the 2-ethylhexanoate and Sn(II) components upon introduction to water. At the circumneutral pH encountered in the environment, these components will occur as the soluble 2-ethylhexanoate anion and insoluble Sn(IV)O2. The former component is readily biodegradable, while the latter is an inorganic species for which testing of biodegradation is neither required nor relevant.
