The characterization of the oil-in-water (O/W) and water-in-oil (W/O) nanoemulsions by droplet size and zeta potential

Code	Type	Size (nm)	Zeta potential (mV)
W1	O/W with soybean oil	256.3 ± 5.5	−19.9 ± 0.8
W2	O/W with squalene	238.7 ± 8.1	−25.2 ± 0.5
W3	O/W with soybean oil and terpineol	216.2 ± 3.7	−19.0 ± 0.6
O1	W/O with soybean oil	33.6 ± 1.6	−2.0 ± 0.4
O2	W/O with squalene	125.0 ± 2.7	−6.0 ± 0.2
O3	W/O with soybean oil and terpineol	18.1 ± 0.3	0.4 ± 0.2
