The average diameter (in mm) of inhibition zones of orange oil ME-loaded films (n = 5) against the growth of S. aureus and P. acnes.

Sample	Average Diameter of Inhibition Zones (mm) ± SD
	S. aureus	P. acnes
FME 20	ND	13.64 ± 0.25
FME 25	ND	15.18 ± 0.09
FME 30	8.32 ± 0.11	16.10 ± 0.02
Control film	ND	ND
Tween 80	ND	ND
Propylene glycol	ND	ND
Ampicillin (10 mg/mL)	32.87 ± 0.96	19.43 ± 0.60

Note: Control film = film containing orange oil instead of orange oil microemulsion; ND = not detected.
