in this study canthaxanthin was produced by dietzia natronolimnaea hs1 and used for incorporation in niosomes after extraction. effect of rotational speed of rotary vacuum evaporator flask (100 and 150 rpm), canthaxanthin concentration (0, 1 and 2 microgram/ milliliter), concentration of poly ethylene glycol 400 (0, 0.1 and 0.2 %), surfactant type (tween 60 and 80, span 60 and 80) and surfactan...

The effects of water/oil volume ratio, type and concentration of demulsifier, water salinity and mixing speed on the average water droplets size in water-oil emulsion are evaluated at different times through NMR measurements.The type and concentration of demulsifier have the greatest effects on the average droplet size with 38% and 31.5%, respectively. The water/oil volume ratio, water salinity...
