Explore Top-Quality Hexamethyldisiloxane (HMDSO) with Aure Chemical
Aure Chemical is a trusted supplier of Hexamethyldisiloxane (HMDSO), a widely used linear siloxane with diverse applications across various industries. Also known as MM, this versatile compound is a fundamental building block in silicone chemistry and an excellent choice for formulations requiring a high-purity, volatile silicone fluid.
Basic Information of Hexamethyldisiloxane
Hexamethyldisiloxane (HMDSO) is the simplest linear siloxane, with the chemical formula (CH₃)₃Si-O-Si(CH₃)₃. It's a clear, colorless, volatile liquid with a low viscosity and a faint, characteristic odor. Its unique properties, including its low surface tension, excellent spreading ability, and high volatility, make it invaluable in many formulations. Unlike longer-chain silicones, HMDSO is highly volatile, evaporating cleanly without leaving residue.

Applications of HMDSO
Hexamethyldisiloxane (HMDSO) is a versatile ingredient used across numerous sectors:
Personal Care Products: Widely used in deodorants, antiperspirants, hair sprays, skin creams, and cosmetics. It acts as a volatile carrier, delivering active ingredients and providing a smooth, silky, non-greasy feel to the skin and hair. Its quick evaporation helps products dry faster.
Electronics Industry: Employed as a cleaning agent, dielectric fluid, and in chemical vapor deposition (CVD) processes for the fabrication of silicon-based materials and thin films, particularly in the production of low-k dielectrics.
Textile Industry: Used as a processing aid and in the formulation of textile softeners and water-repellent finishes, improving the feel and performance of fabrics.
Chemical Intermediate: A crucial starting material for the synthesis of various other organosilicon compounds, including more complex silicones and silylating agents.
Industrial Lubricants and Fluids: Used in specialized lubricant formulations where volatility and low surface tension are required.
Antifoaming Agent: Effective in breaking down foam in non-aqueous systems due to its low surface tension.
Specialty Solvents: Acts as a volatile, non-polar solvent for various organic compounds and polymers.
