Zinc oxide particulate dispersion: ShiseidoRecent Research Landscape
Agglomeration of mineral UV filters causes uneven skin coverage and reduced SPF efficacy. Precise control of particle surface chemistry and size distribution ensures uniform film formation and transparency.
What technical problems is Shiseido addressing in Zinc oxide particulate dispersion?
Particulate aggregation and sedimentation
(3)evidences
Inconsistent particle distribution leads to poor optical performance and physical instability in liquid formulations. Preventing these failure modes ensures uniform coverage and long-term shelf stability.
Particle agglomeration in liquid media
(2)evidences
Inconsistent particle distribution leads to nozzle clogging in inkjet systems and uneven coverage in cosmetic films. Preventing phase separation ensures long-term storage stability and uniform application performance.
Ultraviolet radiation skin damage
(2)evidences
Inadequate protection from solar radiation leads to cellular degradation and photoaging. Mitigating this risk provides essential biological defense and consumer safety.
