Cosmetics Formulation Development

want to mix Pure-Melatonin 3% Phytosphingosine 0.5% Ferulic Acid 1% Glycyrrhetinic Acid 2% WhiteCumin™ 0.2% น้ำหอม 0.5% Just as I saw on the page of the raw material can use Ethyl Alcohol in solubility But there is no information about the ratio. So I want more information. (I will mix the ingredients in this section with the ingredients that are part of the water in the recipe again. I don't want the formula to contain oil. and do not want to use Emulsifier Thank you.

Hello, I can't do it. Although dissolved in alcohol until clear, if added to water will become precipitated Because these ingredients Cannot be dissolved in water
