Cosmetics Formulation Development

I want to ask สีละลายน้ำ Cosmetics (Water-Soluble) that are sold can be mixed with compounds such as ethanol , Can I Distilled Water? Well, I'm going to make a water based product for my scalp and want to color it beautifully because the main ingredient is colorless. So I want to ask (Water-Soluble) that are sold can be used to mix and if applied on the scalp or skin will the color stick or not?

Hello สีละลายน้ำ can dissolve in น้ำกลั่น , but maybe not. can dissolve in แอลกอฮอลล์ , it doesn't stick to me because I use it. in very low quantities, including being washed immediately with water Colors that adhere well to the skin must be a color that dissolves or well dispersed only in oil

If you want a brownish color, which product do you have to order or do you have to mix a lot?

Hello, I don't know. I'm sorry. You have to try to order Mae Si to try and mix them together.
