Hexamethyldisiloxane (HMDSO), identified by its CAS No. 107-46-0, stands as a pivotal organosilicon compound in a myriad of industries. This colorless, transparent liquid, also known as Bis(trimethylsilyl) ether, is the quintessential disiloxane and serves as a fundamental building block in the vast family of silicone-based materials. With its unique chemical structure and desirable physical properties, HMDSO offers exceptional versatility and performance across diverse applications.

Chemically, Hexamethyldisiloxane possesses the molecular formula C6H18OSi2 and a molecular weight of 162.38 g/mol. It is characterized by its low density, typically around 0.76 g/cm3, and a boiling point ranging from 100 to 101 °C. Its low flash point and distinct refractive index further define its handling and application profiles. Produced primarily through the hydrolysis of trimethylsilyl chloride, HMDSO is noted for its high purity, often exceeding 99%, making it suitable for demanding industrial and scientific uses.

The applications of HMDSO are remarkably broad, spanning from personal care products to advanced material science. In the personal care sector, it functions as an excellent base fluid due to its fast evaporation rate and high spreadability. It is widely incorporated into skin creams, lotions, bath oils, suntan lotions, nail polishes, antiperspirants, deodorants, and various hair care products. A notable advantage is its ability to adjust the residence time of other silicone fluids, like Dimethicone, on the skin without imparting a cooling sensation upon evaporation, unlike many other volatile fluids.

Beyond cosmetics, HMDSO finds significant utility in the medical field. It is a key component in liquid bandages or spray-on plasters, providing a protective layer for damaged skin against irritation from bodily fluids. Furthermore, its efficacy in softening and removing adhesive residues from medical tapes and bandages, without causing further skin irritation, is highly valued. In analytical chemistry, HMDSO serves as a reliable internal standard for calibrating chemical shifts in 1H NMR spectroscopy, offering ease of handling due to its lower volatility compared to traditional standards.

Industrially, Hexamethyldisiloxane is indispensable in organic synthesis, acting as a crucial source of the trimethylsilyl functional group. It facilitates the conversion of alcohols and carboxylic acids into silyl ethers and silyl esters, respectively, in the presence of acid catalysts. It also serves as a monomer in the synthesis of long-chain polysiloxane structures and is explored for creating low-k dielectric materials in the semiconductor industry via plasma-enhanced chemical vapor deposition (PECVD). Its use as a reporter molecule to measure tissue oxygen tension (pO2) in biomedical research highlights its unique properties and potential for innovative applications.
