Be careful when using essential oils to make soaps. If you overdo it with an oil base, your soap will not lather well. Besides, it will also feel greasy and unpleasant to the touch. I usually take no more than 1 teaspoon of aroma oil. Such soaps are best not just for hygienic procedures but for washing delicate clothes. I wash my kawaii outfits solely by using hand-made soaps. They don’t damage cloth, and the aroma is much better than any artificial perfumes. By the way, if you want to add a large amount of dry medicinal herbs, grind them and sift them through a sieve to not scratch the skin.

Opacity generally comes down to one of two things. Either the substance is absorbing the light as it goes through (which would make it dark, or give it color), or it is scattering the light. In the case of the above compounds, and your massage oil, it is due to light scattering of the surfaces of microcrystals within the solid. When these things get dissolved is no longer any sort of crystal structure, so there are no surfaces to scatter light, and since these compounds don’t absorb light in the visible spectrum the light just goes straight through LSI.Good luck on that massage tho.
