So as I said, soaps are detergents; not all detergents are soap. I don't
think your original statement is tenable.

And just to add to the confusion, the liquid synthetic detergent in my
bathroom is labelled "Soapless Soap", which is an oxymoron.

Probably the best, and the only unbiased page that came up in a quick
search. I did find a great many tinfoil hat pages first

Soap, in its simplest form, is rendered fat plus lye.


More generally, it's a metallic salt of a fatty acid. The ring around the
bathtub is a soap, mostly sodium stearate, though not very useful for
cleaning purposes. "Rendered fat" is too restrictive, because that implies
that it has to be animal fat, which isn't true. It also doesn't have to be
lye, but can be any alkaline substance -- historically, it has often been
potash, which is certainly not lye. But we digress -- the usual soaps are
detergents.
