Yes, there can be a lot of additional ingredients added to dishwasher soap and I had heard of enzymes before.

I have to admit I'm a bit skeptical of their effectiveness. Enzymes can usually be denatured pretty easily and if they are in a solution of hot detergent, I'd be amazed they'd stay intact enough to actually do what enzymes do.

That said, there are enzymes that are pretty robust, so I could be completely off base.

Edit: I am off-base, apparently there are super stable amylases that can survive 106C water.[1]
