This understanding will help create a product that performs exactly the way the formulator designed it to perform. It is also important, when making blends, for a formulator to know if the components of the blend will separate upon cooling. Even when a small amount of syneresis is present in a blend, the product can feel slimy or have a bad appearance in a cosmetic product. With a good understanding of these two pheonena, it is possible for a formulator to tune not only the physical properties of cosmetic product, but also the product's appearance.
