Hello. 1. The word dissolve means to dissolve from powder to liquid, but Vitamin E dl-alpha tocopherol and Butylene Glycol is already in liquid form. So no need to melt again 2. Vitamin E is an oil and is incompatible with water. Must be coordinated with various cream maker. 3. What components does the formula contain? Please inform the formula details. 4. The team has already given an answer to this question. Which is a question asked by the same member in another thread. 5. If there is active substance dissolved in water and active substance dissolved in oil. In the same formula, recommend Dimethyl Isosorbide (DMI) , according to the team tested, it is effective in both active substances, water and oil.
