Abstract:
Silicone antifoam emulsions are widely used in various industries to control foam formation during the manufacturing process. Foam can be a problem in many industrial processes, reducing efficiency, increasing costs, and even product defects. Silicone antifoam emulsions offer an effective solution to this problem, providing excellent foam control properties across a wide range of applications. The stability of silicone antifoam emulsions is influenced by various factors such as emulsifier type and concentration. By carefully considering these factors during formulation, processing, and storage, it is possible to develop highly stable silicone antifoam emulsions that effectively control foam in diverse industrial applications. This study investigated the effects of multiple emulsifiers on the stability of silicone antifoam emulsions. Using the foam system based on an anionic surfactant, functional tests of antifoams were performed. The results showed that the use of an emulsifier improves the stability of silicone antifoam emulsion. However, the improvement of emulsion stability performance is more observed in Span 60 than in the other emulsifiers.
