รบกวนถามข้อมูลการละลายสารกันเสียหน่อยค่ะ

Need help and get help on cosmetics formulation development

Please ask for information on solubility of preservatives.

I took สารกันเสีย Caprylhydroxamic Acid to dissolve with Butylene Glycol as the information says but it precipitates into white flakes, not dissolved. Then put it in a portion of the water. It was the same scale. When it is heated, it melts, but once it cools, it becomes flakes as before. Is it normal for this kind of substance? (Recipe to make a very liquid serum) or สารกันเสีย This one is suitable for cream/gel texture, very confused.

Hello, I recommend using Mild Preserved Eco 1-2% in the formula instead.
