nisht: I don’t check but I have seen detergents with a Badatz in Israel. Also, even if soap comes into contact with a tablecloth which comes into contact with food, who cares? There will be no Blios or even a Chiyuv of Hadacha from that contact.
The fallacy of this thread is the assumption that just because something has a Hechsher means that someone thinks it needs a Hechsher.
