Hexamethyldisiloxane is a colorless and transparent liquid. It is easily deliquescent, flammable, and has the risk of causing combustion when exposed to high heat, open flame, and strong oxidizing agents. Boiling point 99.5℃. Flash point -1.1℃. Relative density (d2525) 0.7606. refractive index 1.3750. insoluble in water, soluble in many organic solvents.

Applications:

1. 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.
2. It is often used as a capping agent in the production of silicone oil, or as a cleaning agent for silicone rubber, pharmaceuticals, gas chromatography stationary fluids, analytical reagents, hydrophobic agents, and medical electronic components.
