Additional information


not required (glyoxal is readily biodegradable). Moreover, dialdehydes such as glyoxal are stable against hydrolysis at pH 4 -9 (WoE for Hydrolysis, 2018).


In air, glyoxal is expected to be rapidly photodegraded by OH-radicals with a half-life of 1.4 d (Plum, 1983; ECT, 2008).

Photodegradation processes in water are of low relevance (BASF, 2007).


No data are available on phototransformation in soil.
