Latex paint has no latex in it. It's a water based emulsion of various stuff, mostly very small particles acrylic. It's supposed to be water proof once it's dry, but they rarely are, because of the failure to remove the other non-water solvent from the paint. Heat and soap help get water back into the paint, which makes it soft, which makes it easier to remove.
