I finally got to make a soap bar with frankincense resin powder several day ago. Tried really hard to melt the powder in coconut and shea butter mix. Got oils to around 160F and kept at it for 10-20 min, hoping that it will melt like pine rosin does. No luck. Smaller pieces might have melted somewhat, but it is hard to tell. I still made 600 gr batch of soap with that. Soap looks nice, the smell 4 days later kind of decreased, need to stick the nose into the soap to really smell it. I used 5% PPO like I would with the EOs. The SP was 4% just in case if resin melt and increases the superfat. The batter traces VERY fast. I made soap with pine rosin and pine tar... this traced faster. I was happy that I planned to use single molds. Overall, the soap is nice and leathers well, but not sure it is worse the price.
