Ed, It seems to me that Barry Thornton, the manufacurer of DiXactol doesn't want to make the exact formula public, for obvious reasons. All I could find on his website (http://website.lineone.net/~barry- thornton/dixactol.htm) about it was that it contains pyrocatchin and glycin. Take alook. Maybe if you contact him directly you might have some luck. Regards, ;^D)(posted 8793 days ago)
