Abstract:
The micro-polarity anisotropy behaviour across the aqueous phase of a SDS (sodium dodecyl sulphonate)-hexane reverse micelle (RM) relies on the SDS packing in the oil-water interfacial self-assembled surfactant structure of the RM.

Solubility
A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the minor component. The physical state of a solution—solid, liquid, or gas—is typically the same as that of the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
In a solution, the solute particles (molecules,...
