Applications
Properties :
This product is an alcohol-free oil/water nanoemulsion containing particles with the hydrodynamic diameter of 75-85 nm according to DLS analysis. It also shows remarkable antibacterial activity against Staphylococcus and E. coli bacteria. Nanoemulsions have a much higher surface area and free energy than macroemulsions that make them an effective transport system. Nanoemulsions do not show the problems of flocculation, coalescence and sedimentation, which are commonly associated with macroemulsions. Nanoemulsions could enhance the stability of chemically unstable compounds by protecting them from oxidative degradation and degradation by light. They are transparent or translucent dispersions with ultra-low interfacial tension and long-term physical stability.Emulsions tend to have a cloudy appearance because the many phase interfaces scatter light as it passes through the emulsion. Two special classes of emulsions – microemulsions and nanoemulsions appear translucent. Nanoemulsions are emulsions with droplet size on the order of 100 nm. A typical nanoemulsion contains oil, water and an emulsifier. Since microemulsions are thermodynamically stable systems in equilibrium, they are sensitive to changes in temperature and composition. Therefore, nanoemulsions are attractive for aforementioned applications because they are relatively the least sensitive to physical and chemical changes and they can be kinetically stable over long time scales.
