Phospholipid-stabilized emulsions polymers

The chapter has dealt with the stability and stabilisation of colloidal systems and covered topics such as their formation and aggregation. If the particle size of a colloidal particle determines its properties (such as viscosity or fate in the body), then maintenance of that particle size throughout the lifetime of the product is important. The emphasis in the section on stability is understandable. Various forms of emulsions, microemulsions and multiple emulsions have also been discussed, while other chapters deal with other important colloidal systems, such as protein and polymer micro- and nanospheres and phospholipid and surfactant vesicles. 

The Pluronic non-ionic block co-polymers (poloxamers) may be alternative emulsifiers to the phospholipids, although their nature can also alter the physical and biological behaviour of the fat emulsions. Fat emulsions stabilized by high molecular weight poloxamers were cleared more slowly by the blood than those prepared with low molecular weight polymers [251].
