I want to take a stab at some whipped body butter and in my research came upon a YT video from coastal scents. She went through the whole process and added some dry ingredients that I have not come across in this forum as of yet. I wanted to ask your expert advice on the additives and see if anyone use them in their butters. They are...silica powder, rice powder and boron nitride. She did say what each one brings to the party like nice slip and creaminess, etc. Anyone use these or know of any cons to using these powders? Thanks everyone!
