Chitosan as pH-switchable emulsifier
An emulsion which is stabilized by solid particles absorbing onto the interface between the two phases is called a pickering emulsion. The particles prevent coalescence of the droplets. The development of particulate emulsifiers is highly interesting with many advantages over conventional surfactant systems. Beneficial are the higher stability, better size control and lower toxicity. In this research area the application of chitosan for development of pickering emulsions is promising.
