How should I make this magistal preparation, a lip stick must be

We have received a preparation: R/Vitamin D2 1.5 g Cocoa Butter 62g Boric acid 5g Aqua ad100g (looks like he prescribed Aquaphil) When we heat water and cocoa and then pour together, it does not want to mix. That's why Tween 80 has been remade until it wanted to mix. Then boric acid is done. Boric acid did not really need to dissolve and after cooling everything is just walking. After a few moments, it starts to rework. How can we solve this?
