Hello
I would like to ask if We will prepare the formula in the form of Powder that can be mixed with water, can it be made into a formula for sale? or the formula must be in powder form only.
can be done but with condition packaging time Must be stored without allowing water to evaporate. because if the water can evaporate from the formula
แผ่นมาส์ก will harden in the package instead of on the user's surface. yes
I want to add more extract to the color, but to make the meat in the form of a powder already mixed with water. Can it?
Can it be done?
