Due to the development of several microorganisms that are antibiotic-resistant. Therefore, it became vital to look for alternatives, such as oily plant extracts and nanomaterials made from them that safeguard humans and preserve food against harmful microorganisms. In this study, nanomaterials were synthesized from thyme essential oil, cumin essential oil, and a mixture thereof. The chemical composition of the nanoemulsion was determined by gas mass spectrometry (GC-MS) and the size by zeta potential microscopy and TEM. GC-MS analysis of thyme nanoemulsion showed mainly 7 compounds, of which 1,2,3-propantirylster (32.94%) was the highest. The cumin microemulsion contained mainly 11 compounds, of which oleyl oleate (33.19%) was the highest percentage. The mixture mainly contained 7 compounds of which phenyl palmitolite (31.54%) was the most. Using TEM, the particle size measurements of thyme, cumin, and nano-mixture were 31.70 nm, 31 nm, and 21.9 nm, respectively. There was no aggregation, homogeneous size, and spherical nature. The conductivity, viscosity, polydispersity index (PDI), and zeta potentials were measured to thyme oil nanoemulsion 0.160 ms/cm, 0.8874, 0.260, and -4.70 mV3.99, respectively. The cumin oil nanoemulsion is 0.173 ms/cm, 0.8874, 0.232, and -3.79 mV to 5.79 and mixed oil nano-emulsion, the corresponding values were 0.165 ms/cm, 0.8874, 0.197, and -1.17 mV 10.59from results conclude that we can manufacture nanomaterials from natural materials at very low concentrations, thus reducing their aromatic odor, in addition to the synergistic action between two types of nanomaterials, which may produce new materials with a stronger effect.
