Silicone powders have found applications for different purposes such as lubricants, sensory enhancing ingredients in cosmetic products, water repelling agent in paints, and so on. Hydrophilic nature of their surfaces are useful in stablizing oil or water droplets in immiscible media. One of the most representative examples is water droplets stabilized by hydrophobically modified silica powders in the air that is known as 'dry water'. Silicone powders with hydrophilic surfaces are usually compatible with both water and oils. In mixtures of oil and water, these particles can induce formation of stable water or oil droplets dispersed in oil or water, respectively. In this study, silicone powders with different surface properties are prepared in different methods. The synthesized powders are characterized and their role in mixtures of water and different oils are investigated. |
