want to make spray น้ำแร่ SPF30 Meat clear Not cloudy Please advice สารกันแดด Soluble that helps. SPF30 or similar, currently using Bisdisulizole Disodium (UVA/Water-Soluble) 2% Ensulizole ( Phenylbenzimidazole Sulfonic Acid ) 2% Benzophenone-4 2% Is it enough to know that the above formula gives SPF at how much?

Hello สารกันแดด is water soluble, has a relatively low SPF, can't expect 30 even when used. at a high rate (at the level permitted by the FDA).
