Moreover, the maximum uptake time was significantly prolonged, suggesting an extra absorption pathway for W/O/W emulsions: a lymphatic circulation pathway. The HLB scale ranges from 0 to 20, with 10 corresponding to an emulsifier that is. In addition, the oral bioavailability of pidotimod in rats, after intragastric administration of W/O/W double emulsions, was significantly higher than that of pidotimod control solution. In oil in water emulsions, the oil droplets are dispersed in the water phase. s at 25 ☌ and 300 s(-1), was stable for 1 month at 4 ☌.The density differences allow water to separate by gravity. The elements in the well stream such as oil and water have different gravities. Gravity separation is the most widely used method for oil emulsion separation. The viscosity of oil-in-water in oil emulsion is much lower than the viscosity of water in oil emulsion (Figure 1). A fine W/O/W emulsion, with the encapsulation efficiency of 82 ± 3.4%, mean oil-droplet diameter of 3.93 ± 0.25 μm, and viscosity of 36.4 ± 0.93 mPa For more on how a Heater Treater works, check out our training level 1 series. The emulsion of oil-in-water in oil is better than water in oil emulsion. A modified two-step emulsification procedure was applied to prepare the double emulsions using medium-chain triglyceride as the oil phase, Tween 80 as the hydrophilic emulsifier, and Span 80 alone or in combination with different amount of phospholipids as the lipophilic emulsifiers. The aims of this study were to prepare fine pidotimod-containing water-in-oil-in-water (W/O/W) double emulsions and to investigate the possibility of those emulsions as a delivery system for promoting the oral bioavailability of pidotimod.
