1,1,5,5,5-hexamethyl-3,3-bis[(trimethylsilyl)oxy]trisiloxane

Description:
1,1,5,5,5-Hexamethyl-3,3-bis[(trimethylsilyl)oxy]trisiloxane, with CAS number 3555-47-3, is a siloxane compound characterized by its unique structure that includes multiple silicon-oxygen bonds. This compound features a trisiloxane backbone, which consists of three silicon atoms interconnected by oxygen atoms, and is further substituted with hexamethyl groups and trimethylsilyl ether functionalities. The presence of these groups imparts significant hydrophobic properties, making it useful in various applications, including as a silicone oil or in formulations requiring water repellency. Its chemical stability and low surface tension contribute to its effectiveness as a surfactant and lubricant. Additionally, the compound exhibits thermal stability and resistance to degradation, which enhances its utility in high-temperature applications. Due to its silicone-based nature, it is often employed in cosmetics, personal care products, and industrial formulations, where it can improve texture and enhance performance. Safety data should be consulted for handling and exposure guidelines, as with any chemical substance.
