Has anyone tried lecithin or stearic acid with the emulsifier to thicken? I know lecithin is supposed to be very good for hair. I have both of those on hand and I don't like to add too much wax.

I use Rosemary Oil Antioxidant for a preservative and really like that.

What oils and essential oils have you tried? I have a whole array on hand and would love to hear what others are liking
