Decamethylcyclopentasiloxane (D5) is a cyclic siloxane with the formula (CH3)10Si5O5. It is a colorless, odorless, and viscous liquid that is widely used in cosmetics, personal care products, and other industrial applications. D5 is synthesized by the hydrolysis of dimethyldichlorosilane, followed by ring-opening polymerization and ring-closing depolymerization. The compound is known for its excellent spreading and film-forming properties, making it suitable for use as a silicone oil, emollient, and antifoaming agent. Due to its high volatility, D5 can evaporate from skin and products, contributing to its perceived light feel. However, concerns regarding its potential toxicity and environmental impact have led to increased scrutiny. D5 is often studied to understand its environmental fate, potential bioaccumulation, and possible health effects. It is also explored in research on silicone-based materials with improved biocompatibility and degradability.'
