At first I thought it was because of spinning, but left it for 2 weeks and the bubbles didn't disappear. I don't know why And where should it be corrected?

Hello, please ask the member before adding สารกันเสีย ( Phenoxyethanol SA ) into the formula. Is it foamy yet? Usually Satin Cream Maker will help get rid of bubbles in the formula as well. The team therefore suspected that caused by filling สารกันเสีย in the last step? change from Phenoxyethanol SA as Mild Preserved Eco 1% instead.

It doesn't appear to have a clear bubble during the process. But leave it for several days, it's clearer bubbles. Phenoxyethanol SA reacted with the formula Why is it that I usually use กันเสีย ? กันเสีย This one is regular. Paeonia extract can be used as กันเสีย in this formula?

Hello PaeoniaPreserve™ Can be used in this recipe. Basically, if the formula is still liquid, may add Satin Cream Maker A little 0.2-0.3% of Satin Cream Maker should help get rid of the foam from the formula.
