Essential oils are volatile oils and are very sensitive to heat. I doubt the therapeutic properties survive the lye monster. Yes the fragrance remains, but that's not the part of the EO that is therapeutic, other than on an emotional basis, but the same is true of FO's, the fragrance creates an emotional reaction.
Now having said that - I personally can't guarantee that, it's my opinion only. The only thing I strongly recommend it to understand all the benefits and contraindicators of each essential oil that you want to use. Essential Oils are basically over the counter meds without any controls for quality, strength, purity, etc.
