The nanostructured lipid carrier (NLC) system used the combination of beeswax-oleum cacao and virgin coconut oil (VCO) in this study, it was the development of nanoemulsion (NE) and solid lipid nanoparticle (SLN) delivery systems, which are used as nano-carriers of p-methoxycinnamic acid (PMCA). PMCA a secunder metabolite of champheria galanga has antiinflamatory effect which is difficult to dissolve in water. Several combinations of solid lipids (beeswax-oleum cacao) and liquid lipids (VCO) were prepared, namely F I (60:40); F II (70:30); and F III (80:20) in the NLC system.

The NLC-PMCA system was prepared by the high shear homogenization method, then characterized and subjected to antiinflammatory activity tests compared with nanoemulsion and solid lipid nanoparticle (SLN).

The increasing concentration of VCO in the NLC-PMCA system resulted in lower viscosity, and greater entrapment efficiency, namely in the NLC-PMCA system with a combination of beeswax-oleum cacao and VCO of 60:40. NLC-PMCA with the combination of beeswax-oleum cacao and VCO of 60:40 (F I) has particle size (236.00 ± 17.15 nm) smaller than SLN-PMCA (665.60 ± 72.59 nm) but biger than NE-PMCA (29.27 ± 1.85 nm). Occlucivity of F I NLC-PMCA (41.50 ± 4.00%) higher than SLN-PMCA (33.52 ± 3.65%) and NE-PMCA (33.52 ± 3.65%). PMCA in F I (60: 40) NLC, SLN and NE has the equivalent antiinflammatory activity based on the observations of the PMN cells number in ear skin mice with edema.

The NLC-PMCA with the combination of beeswax-oleum cacao and VCO of 60:40 was the best formula.
