01
Droplet size below 200 nm? Loop back for high-pressure homogenization or sonication.
02
pH between 5.5 and 6.5? Adjust with citric acid or triethanolamine solution.
03
Viscosity suitable for spray application? Dilute with water or ethanol if too high.
Use when scaling up or training on nanoemulsion sunscreen spray production; adapt oil phase, emulsifiers, and spray requirements per formula.
