I don't have any rice bran wax, which other wax would you suggest as a substitute? Or could you use 8% cera bellina wax instead?
The only other wax I tried was beeswax and it was too draggy on my skin. So that's all I can say from personal experience. The only reason I combined the two waxes the first time I made this specific recipe was purely accidental. I had planned to use only one of them as a test, but accidentally picked up the wrong one and by the time my reflexes caught up with my brain, I had already poured in part of the 8% I was going to try with just the one. Then instead of just going with that one, I switched & made up the difference with the other to get the 8%. I never did try one vs the other because I was so pleased with my accidental formula that works so perfectly for me, that I just haven't bothered yet. For me, the issue was that with only MgOH & babassu oil, the stick melted in my car when I travel. It worked fine as a deodorant, but it needs to stay solid in my car, hence the added wax.
If you read back through the thread, you will see other additives suggested for creating a deo stick that is less prone to melting in higher temperatures.
