Hasanyone had experience with adding additives with BB bases. I just tried and added shea butter, cocoa butter,oo, cocount oil, glycerin, and scent. All at 1/2 tsp per 8oz of base, and scent was 3ml. I'm not use if I really lost lather or not. It seems like it still had lather it just took longer to get the lather. So does that mean I lost lather? If you've used their bases how much were u able to add? I know I will have to experiment with what works for me but thought I would ask to keep from wasting supplies. It did make my bar harder which I wanted also. Any help is greatly appreciated.
