Hexamethyldisiloxane
Key words:
As a sealing agent, release agent, cleaning agent, used in silicone rubber, medicine, hydrophobic agent and moisture-proof agent. Hexamethyldisiloxane (HMDSO), with the chemical formula C₆H₁₈OSi₂, is a versatile organosilicon compound widely recognized for its unique properties and extensive industrial applications. This clear, colorless liquid is characterized by its low viscosity, high volatility, and excellent thermal stability, making it an essential component in various high-tech and manufacturing processes. As a member of the siloxane family, HMDSO combines the benefits of organic and inorganic chemistry, offering exceptional performance in surface modification, coating applications, and as a precursor in chemical synthesis.
Key words:
The personal care and cosmetics industries value Hexamethyldisiloxane for its unique sensory properties and compatibility with skin. As a volatile silicone fluid, it provides a lightweight, non-greasy feel in cosmetic formulations, contributing to smooth application and quick drying in products such as antiperspirants, sunscreens, and hair care preparations. Its excellent spreading characteristics enhance product performance while improving skin feel, and its chemical inertness ensures compatibility with a wide range of cosmetic ingredients. Furthermore, HMDSO acts as a carrier fluid in personal care products, helping to evenly distribute active ingredients while evaporating cleanly without residue.
