Foam ≠ good soap. Almost all commercial soaps are decent soaps (for the purpose of killing organisms/viruses) that vary only in how nice they treat your hands, and how they smell. Consumer soaps add foaming agents specifically so people think "they're working" - the foam does nothing. Bar soap is still soap, and works' fine - it's just less convenient to use. Go find an industrial or laboratory soap - that stuff is pure SDS/SLS, flows like olive oil, will remove the top few layers of your skin, and doesn't foam at all.
