I have used Camellia Oil at 10% and at 30% in CP soap recipes. I have had a lot of trouble with it. At 10% the soap takes a long time to harden. At 30% my recipe has still not hardened after 8 days. It is spongy.Has anyone used green tea seed oil as an additive? If so, can you give me some feedback? Did you lower overall SF to allow for this? Any input would be greatly appreciated.
