General 201 silicone oil has good high and low temperature resistance, high flash point, low freezing point, low vapor pressure, good oxidation resistance and chemical stability, can be used for a long time in the high temperature range of -50 ° C - +200 ° C, isolated air or in inert gases, can be used for a long time at 200 ° C, and has a small viscosity temperature coefficient, small surface tension, and large compression rate. It also has excellent electrical insulation properties, arc resistance, corona resistance, moisture resistance and physiological inertia, so it has been widely used in various departments of industrial and agricultural production, national defense industry, scientific research and medical and health departments. In particular, we recommend dimethyl silicone oil for use as defilm agent, defoamer, lubricant (line oil) and for the production of mold silicone rubber. 201 methyl silicone oil in addition to all the characteristics of 201 methyl silicone oil, due to the unique production process does not contain the remaining catalyst and its decomposition products in silicone oil, does not contain metal ions, so non-toxic, tasteless, odorless characteristics are more prominent, non-irritating to the human body, will not cause allergic reactions, and can be compatible with commonly used cosmetic components, These properties make silicone oil can be used in cosmetics production to improve the performance of cosmetics.
