Nano-emulsions: Formation by low-energy methods

The main developments on nano-emulsion formation by low-energy methods in the last five years are reviewed. A general description on nano-emulsions, including issues such as size-range, terminology and classification of low-energy emulsification methods is given in the introduction. Low-energy methods, which use the internal chemical energy of the system to achieve emulsification, are classified depending on whether or not changes in the...
