How likely is it that the average liquid or dish soap will be toxic if swallowed? I know the vast majority of bar soaps are made not to be, and that heavy-duty or antibacterial liquid soap are likely to be, but I'm not sure about the run-of-the-mill ones, and google search throws up all sort of digressions (an oddly high amount of nature living-relayted stuff, notably).
(For the record, it's for a BDSM scene, so I need to know if it's possible for my character to find one she can use safely)
Oh dammit, I might as well ask while I'm at it.
And are any compound found in such soaps likely to become toxic if mixed with urine?
