While Benzalkoniumchloride (CAS Nr.: 8001-54-5) is also a tenside, the stuff
sold for use in air cleaners (at least by Venta) contains also, I think,
Triton-X. Its made its way into many washing detergents (for use at lower
temperatures) and additives (this is what I purchase since its cheaper).
In a water cleaner there is little dangers posed by it (I use it) but its not
harmless stuff:

I have not till now considered it but would not use it without study in any
of my photographic waterbaths.
