Results: The results showed that the IBU-containing SMEDDS consisted of IBU 8.7%, Capryol 8.7%, Acrysol EL-135 66.08%, and propylene glycol 16.52%, with a droplet size of 16.33 ± 0.124 nm and a PDI of 0.185 ± 0.003. It is capable of rapid self-emulsification within 30 seconds of gentle stirring with distilled water (with a volume ratio of 1: 500, v / v) to form a clear microemulsion.
