Phase Behavior in Water-Sucrose Monoalkanoate Systems.

Phase behavior and interfacial curvature in water-oil-surfactant systems

Even during 1995, 60 papers appeared using cosurfacrant in their formulations . If one does not have the choice of optimal surfacrants (there may be various commercial or scientific reasons), it may be helpful to use these add itives (e.g. in emulsion formulations, see below). Quantitative measurements of structures and their interpretation is facilitated, however, if one restricts oneself to t...

Behavior of Water in Certain Heterogeneous Systems

In various models designed to imitate living cells the surface of the protoplasm is represented by guaiacol which acts in some respects like certain protoplasmic surfaces. The behavior of water in these models presents interesting features and if these occur in vivo, as appears possible, they may help to explain some of the puzzling aspects of water relations in the living organism. When suffic...

Experimental Study of Phase Inversion in n-Butylacetate-Water, Kerosene-Water, and n-Heptane-Water Systems in a Rotating Disc Contactor Column

Viscoelastic Behavior of Olive Oil-in-Water Emulsion Stabilized By Sucrose Fatty Acid Esters

Applied Rheology Volume 21 · Issue 5 Abstract: The rheological behavior of the olive oil-in-water emulsions has been studied by varying the oil to water ratio as well as the surfactant concentration. The viscoelastic property of the olive oil emulsions was investigated with a cone-and-plate system, using a Bohlin C-VOR Rheometer. The obtained results indicated that the emulsions with greater oi...

Phase behavior of reverse poloxamers and poloxamines in water.

The phase behavior of two types of poly(ethylene oxide)/poly(propylene oxide) (PEO/PPO) copolymers in aqueous solutions was studied by light scattering, viscometry, and infrared spectroscopy. Both the reverse poloxamer (Pluronic 10R5) and the star type poloxamine (Tetronic 90R4) have practically the same PEO/PPO ratio with their hydrophobic blocks (PPO) located in the outer part. The temperatur...
