Dimethicone is a multifunctional odorless, tasteless, and clear silicone fluid and synthetic ingredient. It is an active compound that functions as an emollient, creating a protective barrier on the skin that leaves a non-greasy feel.
 
Dimethicone is a sensory and texture enhancer, giving products a silky texture and imparting a luxurious, non-greasy feel on the skin. It gives the perception of moisturizing the skin and acts as a slip agent and film former, making products easy to spread and forming a barrier on the skin. Additionally, it has wetting/spreading and conditioning/lubricating properties. Dimethicone has excellent water and sebum repellency, making it wash-off and rinse resistant, and helps control shine. It is ideal for waterproof makeup and sun care products, providing both transient and long-lasting effects on hair and skin.
 
With its low surface tension, dimethicone spreads easily on hair, making it smooth, shiny, and easy to comb. This property protects hair from damage by reducing surface tension while brushing. Dimethicone also enhances the effectiveness of other ingredients, strengthening the performance of sunscreens and stabilizing vitamin C. Studies have shown that vitamin C degradation is low in formulations containing dimethicone.
