Description of key information

DCDPS is hydrolytically stable.

Key value for chemical safety assessment

Half-life for hydrolysis:
1 yr
at the temperature of:
25 °C

Additional information

DCDPS has a half-life for hydrolysis in surface water of more than 1 year based on extrapolation of measured data at 50 °C as evidenced in a valid and conclusive study under GLP according to OECD TGD 111. From the half-life DT50 hydr ,water greater than 1 year, the first order rate constant for hydrolysis in surface water is derived
khydr, water = < 7.9 • 10-5d-1.
