All oxygen bleaches work on the same principle, releasing oxygen. Just as hydrogen peroxide will "kill" germs, so does oxygen bleach per se.
Activated oxygen bleaches, especially those made from TAED combine with sodium perborate to form peracids in wash liquor. This results in a rather powerful disinfection action. Indeed the UK, where wash temps for hospital laundry were mandated at temps >71C for three minutes, TAED oxygen bleaches give the same standard of results at lower wash temps 40C to 60C. TAED will also kill germs even when the amounts used are not enough to shift stains.
Persil by Henkel used to contain TAED, and the box boasted about how sanitary it got laundry. My modern boxes of Persil sensitive list sodium percarbonate, but no bleaching activator (not really needed with percarbonate bleach, as it will remove stains even in cold to warm water, whereas perborate bleaches need temps from warm to hot to boiling to really get going).
One reason given by so many washer repairmen in the UK and Europe for the growing whiff in front loaders, and slime formation is that many detergents today now do not contain bleaches. By this they mean oxygen bleaches and it is because so many persons are wearing coloursm and darks, that cannot or should not be exposed to detergents with any sort of bleaching agents. This combined with low temperature laundry habits is a recipie for creating a bacteria and mould breeding ground inside a washing machine.
