Hello, please ask the members for photos, the nature of the stratification, the separation of the layers into 2 separate liquids, or is it a precipitation of substance?

Hello, the problem is caused by using WaterSoft which although soluble in water but will not be able to dissolve in Glycerin or some types of Glycol. If you check the formula, you will find that some substances in the formula of members such as Fucus Film will contain an element Propylene Glycol is included (check by clicking on the "Technical" tab on the Ingredients page), resulting in such stratification issues. Solution 1. Cut WaterSoft out (for water-based formula or skin spray, please recommend Siliwax Aqua would be a more interesting option) or 2. Add the binder. to help coordinate the formula Do not separate the layers, but in this case may result in the formula thickening. It also requires heat to mix, for example using Milk Lotion Maker 2% to help solder it (in case you don't want to use heat If you don't want the formula to thicken, you may choose Light Lotion Maker 3%, but need to test stability again. that if it is left for a long time, will there be a separate floor or not?)
