Description of key information

No tests available for phototransformation/photolysis. Not required under REACH.


An estimation of the Hydroxyl Radicals Reaction is available with AopWin v1.92 for some substances:


OVERALL OH Rate Constant:


STS = 1.2243 E-12 cm3/molecule-sec


SXS = 3.1131 E-12 cm3/molecule-sec


NH4XS = 3.1131 E-12 cm3/molecule-sec


 


Half-Life:


STS = 8.737 Days (12-hr day; 1.5E6 OH/cm3)


SXS = 3.436 Days (12-hr day; 1.5E6 OH/cm3)


NH4XS = 3.436 Days (12-hr day; 1.5E6 OH/cm3)


Values for STS have been taken as representative for the risk assessment


  

Key value for chemical safety assessment

Half-life in air:
