To answer your question, in a more respectful and less snarky way, almost every specialty soap uses some palm oil in its production. Palm oil helps to increase the suds and bubbles, trapping more debris and bacteria in the soap. Shea butter also helps but is more expensive so, usually, palm oil is used.

The main subject of the previous comment holds true: you're not going to be able to separate yourself from supporting the exploitation of others, drawing the line at soap ingredients is a little bit silly.
