Polydimethylsiloxane silicone emulsion
Polydimethylsiloxane (silicone) emulsion is the most widely used silicon-based organic polymer and is particularly known for its unusual rheological (or flow) properties. Further, it is used in contact lenses, medical devices to elastomers and in shampoos (as dimethicone makes hair shiny and slippery). It finds application as an antifoaming agent in food, caulking, lubricants, kinetic sand and heat-resistant tiles. In addition to this, it serves as a critical ingredient in water-repelling coatings such as Rain-X.
