Each person responds differently to essential oils. You may require far less essential oil in your foaming body wash than someone else does. I respond very well to lemon eucalyptus but many of my friends find it very drying. Some of my friends prefer the subtle fragrance of a few drops of Lavender and other's can't detect the fragrance unless I double the drops. So please do experiment. "Less is more" is a good approach. Start with a little and find your fragrance point.
