Silicone surfactants are also amphilic materials but the group other than the silicone-soluble group can be oil- or water-soluble. The silicone surfactant, if composed of silicone- and water-soluble groups, will lower the surface tension of water to around 20 dynes/cm2. Silicone surfactants have the intriguing and commercially viable ability to reduce the surface tension of polar and non-polar liquids to values 15–20 mN/m lower than commonly achieved with organic-based surfactants. Silicone surfactants demonstrate a marked tendency to form aggregate structures featuring surfactant bilayers including vesicles and lamellar liquid crystals. This tendency has been recently applied in the......See More
