I make a coffee scented bar with coffee grounds, coffee, and cocoa butter that I dearly love, however, the scent that I use - Crafter's Choice "Fresh Brewed Coffee" - fragrance oil, accelerates... I HATE that, even though I'm prepared for it. any one have a fragrance oil that they recommend that doesn't accelerate? I mean, one that smells like coffee even after a year? Thanks so much, my friends!
