Manual or traditional filling methods fail to produce repeatable and smooth transitions between different cosmetic formulations. Precise control over spatial distribution ensures aesthetic uniformity and product quality.

Inconsistent emulsion particle size leads to poor product stability and sensory quality. Achieving precise polydispersity control ensures predictable active ingredient delivery and shelf-life.

Manual or static mixing processes fail to maintain uniform shear forces during small-batch production. Precise control over fluid dynamics prevents polydispersity and phase separation in cosmetic formulations.
