DM 100 (Dimethicone 100) has been over 50 years since at early time when polydimethylsiloxane (referred as silicone oil) was used as an anti-foaming agent.
Only if the silicone oil in the lubricating oil is in its insoluble state can it have anti-foaming.
In contrast, if it is in a dissolved state, it not only has no anti-foaming property but also plays a role of foaming agent.
DM 100 (Dimethicone 100) is very important to choose silicone oil with proper viscosity.
It is general to choose the silicon oil with 100~100000mm2/s (25 ℃) viscosity for being the anti-foaming agent.
The low viscosity silicone oil is easily to be dispersed to exhibit anti-foaming property, however with large solubility and poor anti-foam persistence; high viscosity silicone oil has a poor anti-foaming property but excellent continuity.

Safety Profile Of DM 100 (Dimethicone 100):
DM 100 (Dimethicone 100) is generally regarded as a low-toxicity substance with an excellent safety profile, especially when compared to many other industrial chemicals and solvents.
DM 100 (Dimethicone 100) is non-irritating to skin and eyes under typical conditions of use, and it does not cause sensitization or allergic reactions in most individuals.
Due to its chemical inertness and stability, it is unlikely to react adversely in the body or the environment.
However, like any chemical, prolonged or repeated exposure to high concentrations of dimethicone in industrial settings could cause mild irritation, primarily due to physical effects such as dryness or mechanical abrasion rather than chemical toxicity.
DM 100 (Dimethicone 100) has a high flash point (usually above 200°C or 392°F), making it practically non-flammable under normal storage and handling conditions.
This low flammability risk means it is generally safe to use and store without the stringent fire precautions required for volatile organic solvents.
Nevertheless, in extreme conditions—such as exposure to open flames or temperatures well above its flash point—dimethicone can burn, producing carbon monoxide, carbon dioxide, and silicon oxides, which are hazardous combustion products.
Firefighters must use appropriate respiratory protection when dealing with fires involving silicones.
Because DM 100 (Dimethicone 100) is a non-volatile liquid with low vapor pressure, the risk of inhaling harmful vapors or aerosols under normal handling is minimal.
However, during processes involving spraying, heating, or aerosolization, fine droplets or mist may be generated, which could cause mechanical irritation of the respiratory tract if inhaled in significant amounts.
Adequate ventilation, use of personal protective equipment such as masks or respirators, and controlled working environments are recommended to mitigate any potential inhalation risks.
