Refractive index mismatches between aqueous and silicone phases cause undesirable cloudiness when cosmetic emulsions are stored at refrigeration temperatures.

Poorly soluble lipids like ceramides often precipitate or aggregate within anhydrous and water-in-silicone systems, compromising formula homogeneity and stability.

Inconsistent dispersion of colorants and active coloring agents leads to poor saturation control and rapid fading on the skin surface.
