The choice between these emulsions depends on the desired properties and applications, as oil in water emulsions provide a lighter and more easily spreadable texture, while water-in-oil emulsions offer better moisturizing and occlusive properties.
This review aims to provide succinct insights into the stabilization of W/O emulsions, focusing on interfacial design using surfactants, biopolymers, particles and/or combinations thereof that have been researched in the last decade.
Depending on operating conditions and fluid components, crude oils can form stable emulsions with water. In fact, some of the oil's compounds can act as natural surfactants, decreasing the interfacial tension between fluids, promoting emulsification.
the basics of water-in-oil emulsification were understood in the surfac tant industry, but not in the oil spill industry. The literature shows that there is now basic understanding of the formation of water-in-oil emulsions. 1 . Information on the kinetics of formation at sea is less abundant.
The development of stable water-in-oil-in-water (W/O/W) emulsions for edible preservation coatings and films, utilizing their properties, deserves scientific attention. In this study, oregano essential oil and D‑sodium erythorbate were simultaneously loaded into W/O/W emulsions, and the homogenization conditions of the W/O/W emulsions were ...
Water-in-oil emulsions consist of water droplets in a continuous oil phase, and oil-in-water emulsions consist of oil droplets in a water-continuous phase. Figs. 1 and 2 show the two basic (water-in-oil and oil-in-water) types of emulsions.
This applies to all four water-in-oil types: stable and meso-stable emulsions, entrained water, and those oils that do not form any type of water-in-oil mixture. The differences among these...
Depending on the starting oil properties, four types of water-in-oil types are created: meso-stable and stable emulsions, entrained water-in-oil and unstable or those-that-do-not-form...
Water-based enhanced oil recovery (EOR) methods are one of the popular methods in this field. In this method, due to the possibility of emulsion formation is high, and by creating a...
In this review, the sources of oil–water emulsions from different areas and their harmfulness to the environment and economy will be discussed. The classification, the stabilization mechanisms of oil–water emulsions, and the processes of emulsification and demulsification will be considered.
