I'm still a bit of a rookie but a few days ago made a batch of brine bars with 80% coconut, 15% olive, 5% castor, 20% superfat. Used a 25% salt/water solution in which I dissolved the lye. Put in cavity molds and finished in the oven.
A day later and I was already in love with the bars. Amazingly hard and smooth. They lather great already. I used unrefined coconut oil and the smell still comes through, which I love. No other additives.
I recently started smoking again (yay me!) and using this bar gets the smell off of my fingers like nothing else. Even my weirdo cigarette loving cat doesn't bother trying to lick my fingers after washing with this soap. I'm not sure how they will behave in the shower but they are great at the sink.
I can't recommend this type of bar enough! Soleseife for life! Haha.
