Agrochemicals delivery systems

Although nano-emulsions are thermodynamically imstable systems, they may possess high kinetic stability. This property together with their transparent or translucent visual aspect and a viscosity similar to that of water makes them of special interest for practical applications. Nano-emulsions are used in the pharmaceutical field as drug delivery systems [8,17, 18,25,28-33], in cosmetics as personal-care formulations [2,4,6,7,10,19-21,23,24,27], in agrochemical applications for pesticide delivery [3,34,35], in the chemical industry for the preparation of latex particles [9,22,26,36-38], etc. In addition, the formation of kinetically stable liquid/liquid dispersions of such small sizes is of great interest from a fimdamental viewpoint. 

Bifunctional cyclic carbonates with two six-membered rings, as for example bis(5-ethyl-2-oxo-l,3-dioxan-5-yl)methylether (41), are used for the preparation of thermosetting aliphatic polycarbonates. These crosslinked polymers are degradable and have great potential for the preparation of delivery systems in agrochemical and medical applications [81].
