Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

The tin bis(2 -ethylhexanoate) substance is known to dissociate into its 2-ethylhexanoate and Sn(II) components upon introduction to water. The 2-ethylhexanoate portion of the substance has been shown to be readily biodegradable, while the Sn(II) will speciate initially as Sn(OH)2, and spontaneously oxidize in oxygenated water to form the insoluble inorganic solid Sn(IV)O2. Since neither of these dissociated species posses functional groups which are susceptible to further hydrolysis, hydrolysis of the substance is regarded as an unimportant environmental fate process.
