This statistical approach utilized a five-level, two-factor model to construct linear and quadratic relationships between the formulation variables and the desired responses.

The emulgel consisted of an oil phase (oleic acid, Span 80, and Transcutol P) and an aqueous phase (5-FU and Tween 80). High shear homogenization was utilized for emulsification.
