Effect of process parameters on nanoemulsion droplet size and distribution in SPG membrane emulsification

Effect of drug on the emulsion droplet size and size distributions. A nanoemulsion composed of oil, water, PVA and surfactant mixture at the weight ratio of 10/100/1/5 was prepared using an SPG membrane at an agitator speed of 300 rpm, a feed pressure of 15 kPa and a continuous phase temperature of 25 °C.
