Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

DIRECT PHOTOLYSIS (air, water and soil)

TAED and DAED do not absorb light >290 nm (ozone band) and therefore a direct photolysis will not occur.



OH radical induced indirect photolysis of TAED and DAED can be estimated with US EPA AOPWIN Program estimating low degradation half-lives (10 respectively 19h). But as TAED and DAED are high melting solids with low vapour pressure and a low Henry’s Law Constant volatilisation is not an exposure route to be considered. Therefore this fate pathway is not relevant.



TAED is a bleaching activator used under alkaline conditions in washing processes. Under these conditions (pH 10) in presence of persalt a very rapid hydrolysis and perhydrolysis takes place resulting in a DT50 for TAED at pH 10 and 21 degree C of 3 min. (perhydrolyis) and 0.3h (hydrolysis).
