| Summary: | Tamanu oil is derived from the seeds of the tamanu tree or Calophyllum inophyllum, known for its
various benefits, including for treating acne-prone skin. The aim of the present study was to
formulate tamanu oil into an optimal and stable Nanostructured Lipid Carriers (NLC) to enhance its
activity against the acne-causing bacteria Cutibacterium acnes. The formulation of NLC-Tamanu Oil
was optimized using a Box-Behnken Design with solid lipid to liquid lipid ratio (X1), surfactant (X2),
and cosurfactant (X3) as independent variables, and particle size (Y1) and polydispersity index (Y2)
as response variables. In vitro antibacterial activity testing was performed using the broth
microdilution method. The NLC-Tamanu Oil formula was successfully prepared with a particle size
of 281.13 ± 7.32 nm, polydispersity index of 0.301 ± 0.055, zeta potential -19.44 mV, entrapment
efficiency of 99.54 ± 0.38%, and pH of 4.99 ± 0.12. In vitro testing results showed that
encapsulating tamanu oil into NLC increased its antibacterial activity by more than 2-fold, from an
IC50 value of 1.74 µg/mL to 0.76 µg/mL, classifying it as a strong antibacterial agent. NLC-Tamanu
Oil was most stable when stored at 4°C after one month of testing. Based on the findings of this
research, it can be concluded that formulating NLC could enhance the antibacterial activity of
tamanu oil against the acne-causing bacteria C. acnes.
