A recently purchased pack of dishwasher cleaner claimed to have X% of
non ionic surfactant which all sounds very innocent and like the
instruction book for a 1960s girl's chemistry set.

Reading in more detail and looking at the MSDS revealed that it was our
old friend, NaOH. No other ingredients were mentioned.

That'll be what does some of the work, but there will be a non ionic
surfactant as well, since NaOH doesn't fit that definition at all.

I see.

What things fall within that definitiion?
