Decamethyltetrasiloxane

Description:
Decamethyltetrasiloxane, with the CAS number 141-62-8, is a siloxane compound characterized by its unique structure comprising a linear chain of silicon and oxygen atoms, specifically featuring four silicon atoms and a total of ten methyl groups attached to the silicon atoms. This compound is part of a larger class of organosilicon compounds known for their versatility and stability. Decamethyltetrasiloxane is typically a colorless, odorless liquid with low viscosity, making it useful in various applications, including as a lubricant, a surfactant, and in personal care products. Its chemical stability and resistance to thermal degradation contribute to its effectiveness in high-temperature applications. Additionally, it exhibits low surface tension and good spreading properties, which enhance its utility in formulations. Due to its siloxane backbone, it is also hydrophobic, which can be advantageous in certain formulations where water resistance is desired. Overall, decamethyltetrasiloxane is valued for its unique properties that facilitate a wide range of industrial and consumer applications.
