- FunctionsEmollientSolventSkin Conditioning Agent
- Primary FeedstockThe primary feedstocks for cyclopentasiloxane are silicon metal and methyl chloride. Silicon metal is produced by reducing silica (silicon dioxide, SiO2) with carbon in an electric arc furnace. Methyl chloride is typically synthesized from methanol (CH3OH) and hydrogen chloride (HCl), where methanol is often derived from natural gas or coal.
