It has viscoelastic properties. Dimethicone is used as a surfactant, antifoaming agent, carminative in various products such as medical devices, food products, and lubricants. It is used in a number of health and beauty products including hair care products such as shampoo, conditioner, leave-in conditioner, and de-tangling products. On skin, it is also observed to have moisturizing actions.
