Description of key information

Hydrolysis (DTPMP-xK): not hydrolytically unstable 

Key value for chemical safety assessment

Additional information

The requirement to test the substance for hydrolysis was waived as the substance is not susceptible to hydrolytic degradation. This is supported by read-across results for the related acid from dark and sterile controls, in which no degradation (as production of orthophosphate) was observed over time periods of up to 50 days under ambient conditions in water (Schowanek and Verstraete, 1991).
