Silicone oil is a kind of polyorganosiloxane with a chain-like structure of different polymerization degrees. It is obtained by hydrolyzing dimethyldichlorosilane with water to obtain the primary polycondensation ring body. The ring body is cracked and rectified to obtain the low ring body. The ring body, the capping agent, and the catalyst are put together to telogen to obtain a mixture of various degrees of polymerization. The silicone oil can be obtained by removing low-boiling substances by vacuum distillation.
Next, Cosmetic Silicones Manufacturer will introduce how to distinguish true and false silicone oil:
2. Test with fire: use a glass rod or iron rod with a small amount of silicone oil to ignite. The only thing that can ignite and emit black smoke is white mineral oil. Pure silicone oil will not burn when ignited by fire, and is odorless, clear and transparent, and non-toxic. . The ignition point of silicone oil is 320 degrees.
3. Freezing point test method: The silicone oil will not be frozen at -50 degrees, and the fake silicone oil will appear turbid or frozen.
