Protein Fibrils Induce Emulsion Stabilization
Langmuir, 2016The behavior of an oil-in-water emulsion was studied in the presence of protein fibrils for a wide range of fibril concentrations by using rheology, diffusing wave spectroscopy, and confocal laser scanning microscopy. Results showed that above a minimum fibril concentration depletion flocculation occurred, leading to oil droplet aggregation and ...

Modeling stability of double emulsions
2017Abstract Double emulsions are of high potential for drug delivery of active ingredients. They consist of small droplets of one fluid suspended in larger droplets of a second immiscible fluid. The product properties in double emulsions are governed by the droplet size distribution (DSD) of both the internal and external emulsions.

Current Opinion in Colloid & Interface Science, 2004
Proteins are widely used as emulsifiers to facilitate the formation, improve the stability and provide specific physicochemical properties to oil-in-water emulsions. There have been a number of recent advances in the understanding of the ability of various types of proteins to provide these functional properties.

Optimizing organoclay stabilized Pickering emulsions
Journal of Colloid and Interface Science, 2011Oil-in-water emulsions were prepared using montmorillonite clay platelets, pre-treated with quaternary amine surfactants. In previous work, cetyl trimethylammonium bromide (CTAB) has been used. In this study, two more hydrophilic quaternary amine surfactants, Berol R648 and Ethoquad C/12, were used and formed Pickering emulsions, which were more stable

Colloid Surfactants for Emulsion Stabilization
Advanced Materials, 2008Similar concepts of packing should, inprinciple,alsobeapplicabletocolloidalparticles.Ifso,itmightbe possible to control the emulsion drop size and shape withthe same strategy as used for molecular surfactants, providingconsiderable flexibility control to the emulsion.

Emulsion Stability and Stabilization
2004On storage (aging), unexposed and undeveloped silver halide materials tend to change their sensitometric characteristics, especially speed (S), gradient (g), and minimum, and minimum density (Dmin). Usually, speed and gradient decrease, whereas fog increases.

Emulsions stabilized with solid nanoparticles: Pickering emulsions
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2013Pickering emulsions are attractive formulations because they are simple and bear strong similarities with the well-known surfactant-based emulsions. Pickering emulsions have been largely ignored since their early disclosure in 1907 and arouse a renewed interest quite recently.

Conditions for Equilibrium Solid-Stabilized Emulsions
The Journal of Physical Chemistry B, 2010Particular types of solid-stabilized emulsions can be thermodynamically stable as evidenced by their spontaneous formation and monodisperse droplet size, which only depends on system parameters. Here, we investigate the generality of these equilibrium solid-stabilized emulsions with respect to the basic constituents: aqueous phase with ions, oil, and ...
