The formulation was systematically optimized through solubility screening, emulsification efficiency evaluation, and pseudo-ternary phase diagram analysis. Central composite design-response surface methodology (CCD-RSM) was employed to identify the optimal SNEDDS@BA composition, followed by HPMCAS ratio optimization based on supersaturation maintenance in biorelevant media. Comprehensive characterization included emulsification performance, droplet morphology, solid-state properties, in vitro release, and stability. The optimized formulation (mass ratio: HPMCAS-castor oil-RH40-PEG400-BA = 151.5:20:40:40:1) generated homogeneous, transparent nanoemulsions with spherical droplets, achieving an emulsification time of 48.30 ± 0.74 s, a mean particle size of 47.77 ± 2.32 nm, and a polydispersity index (PDI) of 0.259 ± 0.007.
