WHAT IS DIMETHICONE

Dimethicone is a part of the silicone family that comes in the form of a colorless liquid. Dimethicone is a surfactant as well as an emulsifier, unifying water and oil parts of a mixture. Few products have as many uses as dimethicone. Also known as polydimethylsiloxane (PDMS), this silicon-based substance offers numerous benefits across various industries.

USES AND APPLICATIONS FOR DIMETHICONE

Dimethicone uses include anti-aging creams & lotions, automobile polish, conditioners, cosmetics, defoaming agent, dielectric cooling fluid, electrical insulating fluids, eye shadow, foundations, furniture polish, hair care, hair colorants, hair conditioner, hydraulic fluid, leather finishes, lipsticks, lubricant, moisturizing cream formulations, mold release agent, nail polish, paint & coatings, pharmaceuticals,etc.

  • Coatings & Construction: Dimethicone is also a critical ingredient in rubbery silicone caulks, adhesives, and aquarium sealants, as well as water-repelling coatings, such as Rain-X.
  • Personal Care: Dimethicone works as an anti-foaming agent, skin protectant, skin conditioning agent, and hair conditioning agent. It prevents water loss by forming a barrier on the skin. Like most silicone materials, dimethicone has a unique fluidity that makes it easily spreadable and, when applied to the skin, gives products a smooth and silky feel. It can also help fill in fine lines/wrinkles on the face, giving it a temporary “plump” look.
  • Pharmaceuticals: It can serve as an internally taken antiflatulence or antacid medicine, by reducing the creation of foam and gas. It also plays an essential role in treatments for dry skin, diaper rash, and radiation burns. Dimethicone acts as an emollient, which traps moisture in the skin, allowing the body to heal its dry or damaged surface. Another topical use for dimethicone is in treating head lice.
  • Industrial: It performs well in hydraulic applications due to its ability to withstand extreme heat and cold. Engine oil, hydraulic fluid, and transmission fluids are some products that benefit from the antifoaming properties of silicones.
  • Food & Nutrition: Antifoaming agents added to oil prevent it from bubbling over and splattering when heated. They can also prevent excessive foaming of alcohol and other beverages during and after production.
  • Others: Dimethicone is an important component in several toys, including Silly Putty, to which it imparts its unique viscosity and elastic properties, and Kinetic Sand, which mimics the physical properties of wet sand and can be molded and shaped into any desired form.
