AEROSIL® R 816 fumed silica powder offers an alternative technology to stabilize oil/water emulsions. Due to the special surface modification of the silica both hydrophilic and hydrophobic properties are introduced in just one material. This enables AEROSIL® R 816 to enrich at oil/water interfaces and thereby stabilize oil droplets in a continuous water phase by the Pickering effect.Furthermore, AEROSIL® R 816 brings structure to the continuous water phase and increases its viscosity which limits the mobility of the oil droplets, thereby providing for even more emulsion stability.
