Phase-inverted emulsified surfactant systems: ShiseidoRecent Research Landscape

Agglomeration of mineral UV filters destabilizes phase boundaries and causes uneven application. Modifying particle surfaces ensures uniform dispersion and phase stability in complex emulsion systems.

What technical problems is Shiseido addressing in Phase-inverted emulsified surfactant systems?

Poor emulsion stability

(3)evidences

Fine particle metal oxides in phase-inverted systems frequently suffer from agglomeration and poor dispersion stability. Resolving these failure modes ensures uniform protective coverage and prevents phase separation in complex cosmetic matrices.

Emulsion thermodynamic instability

(2)evidences

Phase-inverted systems are prone to droplet coalescence and separation over time. Stabilizing these complex structures prevents product failure and maintains sensory consistency.

Interfacial phase instability

(2)evidences

Spontaneous phase separation and droplet coalescence limit the shelf life of cosmetic formulations. Preventing these degradation mechanisms ensures product consistency and long-term efficacy.
