We may never know! I got them for Christmas from my husband who bought them from Amazon and there was nothing in the box they came in that said. They did mention good in soap, however, so I took that to mean 'good for Deb's CP'! lol Honestly, I should have whisked them in, instead of sb, but I wanted to get to the pour! lol They *may* have stayed a little more fluid that way. And thanks! I am still so happy that I can get to emulsion and recognize that and then go from there. I WILL be doing this again!
