Cosmetics Formulation Development

Make a water-based roll-on. The bottle is like a tongue ball. The question is, the roll-on contains almost 80% water. 1. In the formula, there is Ceteareth-20 I think I'll take it. Can it be dissolved with Zinc, right? 2. Enter Zinc Oxide which one is better between nono Zinc Oxide r or micronized Zinc Oxide ? nano Zinc Oxide or micronized Zinc Oxide r good After reading this, I'm confused. When I choose which one to use. 3. Can you tell me how to melt the zinc? Thank you.
