Hexamethyldisiloxane

Description:
Hexamethyldisiloxane, with the CAS number 107-46-0, is a siloxane compound characterized by its unique structure, which consists of two silicon atoms connected by oxygen atoms, with six methyl groups attached to the silicon atoms. This compound is a colorless, odorless liquid that is non-toxic and has low volatility. It exhibits excellent thermal stability and chemical inertness, making it suitable for various applications, including as a silicone oil, lubricant, and in the formulation of personal care products. Hexamethyldisiloxane has a low surface tension, which contributes to its effectiveness as a spreading agent and solvent in cosmetic formulations. Additionally, it is hydrophobic, providing water-repellent properties. Its low viscosity and high flash point enhance its utility in industrial applications, including as a carrier fluid in hydraulic systems and as a component in silicone-based sealants and adhesives. Overall, hexamethyldisiloxane is valued for its versatility and stability in both consumer and industrial products.
