What does it list as the ingredients? If it just says that it contains cocoa butter, then I wouldn't hesitate to use it.
Also- Sprouts used to sell un-refined cocoa butter in little 2 oz. tubs a few years back. I don't know if they still do or not nowadays, but if you have one nearby, you could pop in and see.
It says 100% cocoa butter but it's almost 1.50 per oz and I need about 160z for a patch.. That's way too much money so I need to find a container of cocoa butter....
