In enhanced oil recovery, not only the low-tension performance, but also the robustness at optimum formulation is an important issue. The fourth part of our review series is dedicated to robustness, defined as the width of the zone exhibiting three-p

The effects of surfactant molecules involved in macro-, mini-, nano-, and microemulsions used in cosmetics and pharmaceuticals are related to their amphiphilic interactions with oil and water phases. Basic ideas on their behavior when they are put to

Drilling fluids are generally emulsions, either oil-in-water (O/W) or water-in-oil (W/O), with an aqueous phase containing various electrolytes and an oil phase ranging from hydrocarbons to polar oils. Such multiphasic systems are stabilized by surfa

Anionic extended surfactants of the alkyl polypropylene oxide sulfate type are found to obey the linear correlation lnS = k ACN for optimum formulation (three-phase behavior) of ionic surfactant–oil–water systems, with a k value essentially the s

The sequential injection (SIA) technique was applied for the on-line preparation of an "oil in water" microemulsion and for the determination of aluminum in new and used lubricating oils by electrothermal atomic absorption spectrometry (ET AAS) with

All variables capable of altering the physico-chemical formulation, including temperature, are included in a generalized concept known as the hydrophilic-lipophilic deviation (HLD), which measures the departure from the reference state at which the s

Surfactant-oil-water systems in which the surface active substance is a mixture of carboxylic acid and its sodium salt (soap), exhibit emulsion property maps that are consistent with the phase behavior and the general emulsion phenomenology. However

The phase behavior of cationic surfactant/oil/water/alcohol systems was systematically scanned to correlate the attainment of three-phase microemulsion-oil-water systems with the following formulation variables: water phase salinity as sodium chlorid

The phase behaviour of surfactant-oil-water systems is affected by the so-called formulation variables, i.e. by the nature of the components or their physicochemical characteristics. One of the formulation variables is the nature of the oil, often re
