HELP! Soap seized - which essent oil did it?
I was making my first ever CP batch of mint/thyme soap. I used same formula as always (aside from essential oils).. The essential oils used were a 1/2 1/2 mix of Spearmint essential oil and White Thyme essential oil. Soap seized immediately upon introduction of essential oil mix. Question is: Was it the spearmint? Was it the Thyme? OR Was it the fact that they were both in there together? Does anyone know? I'd like to make a batch of spearmint, but if that is the one that seized my current batch, I would refrain from doing so. Nor do I want to expend the energy, time, or money to try spearmint w/out knowing.
Appreciate any help anyone can give.
