Hello 12H Fix soluble in น้ำหอม need to test the solubility first. that can dissolve into น้ำหอม in case of insoluble or difficult to dissolve Try to consider using 8H Fix instead. It will be easier to dissolve. which can be dissolved in both แอลกอฮอลล์ and น้ำหอม any?
Thank you for your advice. Now I'm going to choose the ingredients. น้ำหอม from nature to develop it's own. If you get stuck anywhere, you need to ask for more advice. Thank you.
