1. WaterSoft vs. Yerba Santa Protein, which one feels softer on the skin? (don't want to use silicone)
2. Does PhosphoMax ™ need oil in the formula? How many % should I use for a lightweight lotion formula? Please ask for directions. There is no explanation of how to use it. Must the formula be blended at a speed of at least 1000 rpm for at least 15 minutes* like Phospholipid ?
