Since you’re referring to my parallel comment, I figured I’d let you know that your comment seemed to imply that talc was an active ingredient used for weight loss.
I did not name Orlistat, I named the medication alli®. alli® contains talc. You can't obtain alli® without talc, AFAIK. Orlistat does not contain talc, but Orlistat is not alli®.
