Polydimethylsiloxane (PDMS), also known as dimethylpolysiloxane or dimethicone, is a silicone polymer with a wide variety of uses, from cosmetics to industrial lubrication and passive daytime radiative cooling.
It is particularly known for its unusual rheological (or flow) properties. PDMS is optically clear and, in general, inert, non-toxic, and non-flammable. It is one of several types of silicone oil (polymerized siloxane). Its applications range from contact lenses and medical devices to elastomers; it is also present in shampoos (as it makes hair shiny and slippery), food (antifoaming agent), caulk, lubricants and heat-resistant tiles.
Upgrade your industrial and consumer products with OSi Silicone's Dimethicone/Polydimethylsiloxane, a versatile silicone oil known for its exceptional physical and chemical properties. Available in a wide range of viscosities, this silicone oil is highly soluble in organic solvents, making it easy to incorporate into various formulations. It emulsifies effortlessly in water using standard techniques, though it remains insoluble in water and many organic compounds. This unique solubility profile, combined with its low surface tension and high lubricity, makes Dimethicone/Polydimethylsiloxane an invaluable ingredient in numerous applications.
Excellent Properties
Dimethicone's properties include excellent resistance to extreme temperatures, good dielectric properties, and high compressibility. It demonstrates minimal viscosity change with temperature fluctuations and boasts strong oxidation and aging resistance. These features make it an ideal choice for thermostatic fluids, dielectric fluids, and lubricants. Its water-repellent nature ensures that treated surfaces resist water penetration, causing water to bead up and roll off. This characteristic is particularly beneficial in polishes, where low-viscosity Dimethicone facilitates easy application and rubout, while high-viscosity variants enhance gloss depth.
Industrial Applications
In industrial applications, Dimethicone/Polydimethylsiloxane serves as a lubricant and heat-protecting agent for textile threads, an anti-blotting agent for photocopying machines, and an ingredient in maintenance products like wax and furniture polishes. Its ability to reduce surface tension and improve flow makes it a valuable additive in paints, providing anti-cratering and anti-scratching effects. Additionally, it acts as a mold release agent in plastics and metal castings and offers excellent lubrication for elastomers and plastics when used with suitable metals.
Application in Cosmetics
In the cosmetics industry, Dimethicone/Polydimethylsiloxane is prized for its ability to form a non-greasy, protective film that allows the skin to breathe while resisting water and irritants. It is a key ingredient in hand creams, skin protectants, suntan lotions, and hair grooming aids, providing both protective and aesthetic benefits.
