Description of key information

The following study has been submitted to address the hydrolysis endpoint:
Schilt, R., J. M. de Wolf, and D. van de Lagemaat (2005). Dibutyltin di-laurate (DBTL, CAS # 77-58-7): Solubility and hydrolysis. Testing laboratory: TNO Analytical Sciences, Zeist, The Netherlands. Report no.: TNO Study V6140. Report date: 2005-02-10.
The study has been allocated a Klimisch score of 2 and so is considered to be the key study for this endpoint.

Key value for chemical safety assessment

Half-life for hydrolysis:
1 h
at the temperature of:
20 °C

Additional information

The hydrolysis half-life for dibutyltin dilaurate could not be determined. However, hydrolysis is concluded to initially occur rapidly but then an equilibrium between DBTL and DBT mono-laurate probably exists. DBT mono-laurate was detected in all samples. DBTO was not detected indicating that DBT without ligands was not formed in large quantities.
