Description of key information

Tributylamine is stable in aqueous solution under ambient conditions.

Key value for chemical safety assessment

Additional information

Tributylamine is not expected to hydrolyse in the aqueous environmental compartment at ambient conditions due to its chemical structure (GUBDH, 2008).

Moreover, in accordance with column 2 of REACH Annex VIII, a test on hydrolysis is not required for compounds determined to be readily biodegradable. This applies for the submission substance.
