Hexamethyldisiloxane

Hexamethyldisiloxane (HMDSO) is a clear, colorless, volatile liquid with a mild, chloroform-like odor. It is an organosilicon compound—specifically, a symmetrical disiloxane—and exhibits low surface tension, high thermal stability, and low boiling point (100–102 °C) with negligible water solubility. HMDSO serves primarily as a chemical intermediate in the synthesis of silicones, including silanol-terminated polydimethylsiloxanes and functional silanes used in crosslinking systems. Its principal applications are in silicone polymer production, surface modification agents, and as a silylating reagent in analytical chemistry and semiconductor manufacturing.

Hexamethyldisiloxane is used as a base fluid in a wide range of personal care products that require fast evaporation and high spreadability. When blended with Dimethicone fluids, It can adjust the residence time of the silicone on the skin. Unlike other volatile fluids, Hexamethyldisiloxane Fluid does not cool the skin as it evaporates. Hexamethyldisiloxane is used as a carrying agent and diluent in the following: skin cream lotions, bath oils, suntan lotions, nail polishes, antiperspirants, deodorants, hair sprays and other beauty and hair care products.A silicon based compound that can be used to create potentially biocompatible materials.Used as a monomer in the synthesis of long chain polysiloxane structures.Used in the methylation of mercury(II) salts.
