CASE ANALYSIS

Scenario

A formulator needs to produce a stable ZnO nanoemulsion sunscreen spray with SPF 50+, sub-200 nm droplets, and sprayable viscosity.

Key decisions

  • High-shear homogenization needed?
  • Droplet size below 200 nm?
  • Target pH 5.5-6.5?
  • Viscosity 100-300 cP?

When to reuse this

Use for pilot-scale development, SOP training, or troubleshooting nanoemulsion sunscreens.
