Description of key information
Additional information
The tin bis(2 -ethylhexanoate) substance has a vapor pressure of 0.3 Pa, indicating a low potential to become an atmospheric pollutant. However, if introduced to the atmosphere, its reaction with photochemically generated hydroxyl radical is expected to be a dominant fate process. The half-life for this reaction is estimated to be 1.6 days. Based on this estimated half-life, the substance is not expected to be transported for long distances in the atmosphere.
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 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. Biodegradation will be the dominant process affecting fate/lifetime of this substance in the environment, and the expected rapid rate and full extent of biodegradation will prevent the substance from persisting or accumulating in the environment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
