I got a sample of Rustic Lodge FO from Rustic Escentuals. I used it in a small batch of CP soap recently. After it cured for a couple weeks the color darkened so I looked up the info on it and it says it is NOT body safe. ??? I did not realize they would send a sample in a soap supplies order that was not intended for use with soap. I have never ordered anything but soap supplies from them. They have not answered my email and I tried to call but got the voicemail. My question is, do I have to throw this away? I'm embarrassed to even ask but I don't know what to do with it. Thank you for your help!
