น้ำกลั่น --------------------------------------------- Question is 1 . I use
1,2-Hexanediol as a solvent instead of using Glycol in the formula, can it be done? 2. How I use
Phospholipid 2% is an Emulsifier that combines water and oil. Is it enough? 2.1 There is a recommendation written that
though
Phospholipid (
Hydrogenated Lecithin ) can act as an emulsifier, but should be selective. is co-emulsifier, there should be a main emulsifier in the formula to perform the function of coordinating the formula with
if
Phospholipid 2% in this formulation is not suitable or is there a better way to mix oil and water which emulsifier should be used? instead? and how much to use? 2.2 How to calculate to know how much quantity to use? I am very confused about choosing Emulsifier. I try to search for information and understand HLB principle but I don't understand how to determine the quantity. 3. From this formula, is there anything that needs to be adjusted or not? Please advise, thank you.
