I always wonder if caffeine can be absorbed from the pores of our skin by washing with coffee soap. Of course that means caffeine has to survive soap making when the fatty acid is reacting with the lye. I can never find out the truth unless I have lab extensively testing the soap out. Until I'm a millionaire and have the extra $ to send my soap to the lab, I'm just going to make the soap and test it out on myself. I'm thinking, even if it's not for the caffeine injection, it is still an yummy soap to shower with. What kind of coffee lover would not like the idea of drenching in (what else of course coffee) in the morning shower for an extra pick me up?!
This batch is made with triple espresso shots, triple grind coffee powder, coconut milk, and scented with yummy Colombian coffee fragrance, then top off with caramel scented cream top!
I knew the fragrance oil I used for the top cream has certain percentage of vanilla and it would discolor to some kind of caramel or tan. But I really want it lighter, like the actual foam in the espresso drinks. I added some titanium dioxide to lighten it up but it didn't work as well as I thought, look at what happened a month later, the top still darkened!
