Oil-in-water emulsion phase stability: ShiseidoRecent Research Landscape

Phase separation in high-pigment lip formulations leads to uneven application and poor wear resistance. This architecture stabilizes the oily phase within a continuous aqueous matrix to ensure uniform film formation.

What technical problems is Shiseido addressing in Oil-in-water emulsion phase stability?

Lip cosmetic phase separation

(8)evidences

Lipid-based cosmetic formulations suffer from coalescence and oil-water layering over time. Preventing this degradation ensures uniform color distribution and prolonged shelf life.

Structural instability in emulsions

(5)evidences

Non-uniform dispersion of colorants in liquid and solid lip formulations leads to poor aesthetic coverage. Achieving homogeneous pigment suspension ensures consistent color payoff and prevents streaking during application.
