Well, while I agree that Hashgacha is totally unnecessary, there is definitely a makom leHachmir where we know its derived from animal fat, according to the M”B. (see end of siman 326 B”H). You can argue that its totally Nifsal MeAchilas Kelev as the Aruch HaShulchan does, but in any case, where the ingredients does not indicate any fat etc, it is more than enough even leHachmir.
Unless you chew your hair like Reb Yid and 770…
