Biphasic emulsion phase morphology: ShiseidoRecent Research Landscape

Phase separation in complex UV filter blends leads to inconsistent protection and poor shelf life. These innovations engineer the interfacial tension and droplet distribution to maintain formulation integrity.

What technical problems is Shiseido addressing in Biphasic emulsion phase morphology?

Interfacial phase instability

(17)evidences

Insufficient film uniformity and low SPF retention on skin surfaces. Consistent coverage prevents solar-induced dermal damage and photoaging.

Inadequate ultraviolet radiation protection

(10)evidences

Incompatible active ingredients in biphasic systems lead to phase separation or precipitation. Preventing these failures ensures uniform photoprotection and shelf stability.
