“…Oncreasing the concentrations of PGPR from 2 and 10% was significantly decreased the average particle sizes of the W/D nanoemulsions from 276 to 168 nm, respectively (data are not shown). Similarly, Matos et al (2014) reported that the mean droplet sizes of W/D/W emulsions containing trans-resveratrol were decreased when the addition of PGPR was elevated. Therefore, it was found in the present study that the optimum concentration of the primary emulsifier (PGPR) for the production of W/D nanoemulsion was 10%, since the smallest particle size (168 nm) was obtained among all the samples.…”

The aim of this study was to optimize conditions for producing water-in-oil-in-water (W/D/W) nanoemulsion and spray-dried nanocapsule of red ginseng extract. Based on emulsion stability and average particle size analysis, optimum conditions to produce W/D/W nanoemulsion were: ratio of core to coating material, 3:7; primary emulsifier, 10% polyglycerol polyricinoleate; ratio of W/D phase to coating material, 1.5:8.5; secondary emulsifier, 10% polyoxyethylene sorbitan monolaurate; solvent, 20% ethyl acetate; secondary coating material, 10% maltodextrin (MD). Under these optimized conditions, particle size of spray-dried nanocapsules coated with MD of red ginseng ranged from 100 nm to 500 nm, based on response surface methodology with the highest yield (up to 99.7%). Results of the present study can be used to further optimize conditions to produce W/D/W nanoemulsion and spray-dried nanocapsule of red ginseng extract.

“…Therefore, in the present study used the water-in-oil-in-water (W/D/W) emulsion because it can be a longer storage life and dried into a powder form. Additionally, W/D/W emulsion can easily be increased with bioavailability of red ginseng extract (Matos et al, 2014).…”

“…Studies have shown that W/O/W emulsion can be successfully formulated using miglyol 812. 6 A previous report on the molecular structure of both oil and emulsifier are important when identifying the stability of the emulsion. Effect of CaCl2 and BSA concentration on droplet size Figure 2 shows that addition of up to 0.3% (wt) CaCl 2 significantly decreased droplet size (p < 0.05) in all formulated emulsions.…”

“…Water-in-oil nanoemulsion is of interest for delivery purposes and for design of stable double emulsions. [1][2][3][4][5][6][7] The multiphase, compartmentalized structure of double emulsions makes them suitable for design of delivery systems and controlled release of sensitive components for production of low calorie, reduced-salt products, masking of off-flavors, prevention of oxidation, and protection of probiotics in food and drug products against gastric juices.…”

The preparation and characterization of activeloaded microparticles for cosmetic textile applications were studied in this work. The double emulsion diffusion/ evaporation technique was served and the Eudragit® RS100 (ethyl acrylate and methyl methacrylate copolymers) was used as biodegradable polymer. Two actives molecules, vitamin E and Lauryl isoquinolinium bromide (LIB) were successfully loaded during the formulation. Obtained particles were spherical in shape with a little variable diameter about 1 μm and zeta potential of 55 mV. The cutaneous penetration of the particles was evaluated by dermal microdialysis, tape stripping, and punch-biopsy techniques from ex vivo human skin. LIB or vitamin E concentrations in the different layers of the skin were analyzed by high-performance liquid chromatography method. Finally, these particles were adsorbed onto a textile in optimized conditions. The scanning electron microscopy is used to confirm the total threads coverage by particles.
