Frequently Asked Questions

!What does the "350" in dimethicone 350 mean?

""350" refers to a kinematic viscosity of about 350 cSt (25°C), a viscosity grade of dimethicone (PDMS). A higher number means higher viscosity. Besides 350, grades such as 50, 100, 500 and 1000 are available, selected by lubrication, defoaming or skin-feel needs.

!What is dimethicone mainly used for?

"It is widely used in cosmetics (smooth, film-forming skin/hair feel), premium lubricants, anti-vibration and insulating oils, defoamers, release agents, polishes, metal moisture/rust-proofing and building waterproof coatings, and as a polyurethane foaming aid.

!What information should I provide to get a dimethicone quotation?

"Please provide the required viscosity grade (e.g. 350 cSt), purchase quantity, application (cosmetic/industrial grade), packaging requirement, destination, and whether COA, MSDS or other documents are required, so Bio-CORNIGS can match the product and quote accurately.

!What is the difference between dimethicone, silicone emulsion and simethicone?

"Dimethicone is the pure silicone fluid (oil); a silicone emulsion is the fluid emulsified into a water-based, milky-white product; simethicone is a blend of silicone fluid and silica, mainly used as a pharmaceutical antifoam/anti-gas agent. Their uses differ, so please specify the required form and grade.
