CAS 541-05-9: Hexamethylcyclotrisiloxane

Description: Hexamethylcyclotrisiloxane, with the CAS number 541-05-9, is a cyclic siloxane compound characterized by its unique structure consisting of three silicon atoms and three oxygen atoms, each bonded to methyl groups. This compound is a colorless, odorless liquid at room temperature and is known for its low viscosity and volatility. Hexamethylcyclotrisiloxane exhibits good thermal stability and is resistant to hydrolysis, making it useful in various applications, including as a precursor in silicone polymer synthesis and as a lubricant or release agent in industrial processes. Its chemical properties allow it to act as a surfactant, enhancing the wetting and spreading of formulations. Additionally, it is often utilized in cosmetics and personal care products due to its ability to impart a smooth feel and improve product texture. However, like many siloxanes, it is important to consider environmental and health impacts, as some studies suggest potential bioaccumulation and toxicity in aquatic organisms.
