INCI: Yucca glauca Wild harvested Origin: United States. Because of its skin healing benefit, this powder makes a great addition to both body and shampoo bar soaps, and because it contains a slightly "sudsing" action - it will lend that to your finished bars. I add 2 tablespoons before light trace to 1 cup of soap - blend well and work back into the soap pot. Please note, that it will lend a very light brown hue, almost gray brown to your soap base.
