GEA homogenizers are used in pharmaceutical and cosmetic applications and have been achieving excellent results in terms of cell disruption and emulsifying effects for many years. With the NiSoX-Valve, GEA has changed the homogenization process for processing micro- and nanoemulsions for the chemical, pharmaceutical and cosmetics industries significantly, further strengthening this leading position. The new NiSoX-Valve geometry optimizes energy distribution during homogenization, thereby reducing particle size and significantly improving the homogenization effect..
Since 2018, GEA and its customer have been testing the new process intensively using the NiSoX-Valve in production to demonstrate the reduction of particle sizes and uniform particle distribution. In the field study, the emulsion formulation consisted of water (80%), fat phase (15%) and surfactant (5%). The practical tests confirm that the polydispersity index is lower than that of conventional valves, especially for applications in the high pressure range from 700 to 1,500 bar. This improves physical and visual properties such as viscosity, transparency and gloss – all very desirable in the processing of pharmaceutical and cosmetic nanoemulsions. NiSoX leads to near transparent emulsions.
