Core-corona polymer particle morphology: ShiseidoRecent Research Landscape

Interfacial instability in traditional emulsions leads to phase separation and reduced shelf life. Engineering the steric hindrance of core-corona microparticles ensures long-term droplet stability and precise texture control.

What technical problems is Shiseido addressing in Core-corona polymer particle morphology?

Hydrophobic phase separation instability

(5)evidences

Thermodynamic incompatibility between oil and water phases leads to coalescence and physical breakdown. Preventing this degradation ensures long-term structural integrity of cosmetic formulations.

Emulsion phase separation instability

(1)evidences

Thermodynamic instability leads to phase separation and poor shelf life in traditional emulsions. Stabilizing the interface prevents droplet merging and maintains uniform dispersion.
