Is propylmethylsilane diol a silicone oil?

Silicone oil ... Silicone emulsified oil. Used in soap-based body wash. DC-344. Cyclic polydimethylsiloxane. 195. It has a high degree of compatibility with many components in cosmetics, reducing the stickiness of the product. It is used as a co-solvent and solid powder dispersant for refreshing Cream, lotion, facial cleanser, lotion, make-up, perfume.
Silicone oil is a kind of polyorganosiloxane with chain structure with different polymerization degrees. It is obtained by hydrolyzing dimethyldichlorosilane with water to obtain a primary polycondensation ring body. The ring body is cracked and rectified to obtain a low ring body, and then the ring body, capping agent, and catalyst are put together to obtain each A mixture of different polymerization degrees can be obtained by vacuum distillation to remove low-boiling substances.
The most commonly used silicone oil, all organic groups are methyl, called methyl silicone oil. The organic group can also use other organic groups instead of part of the methyl groups to improve certain properties of the silicone oil and apply to various applications. Other common groups are hydrogen, ethyl, phenyl, chlorophenyl, trifluoropropyl and so on. In recent years, organically modified silicone oil has been developed rapidly, and many organically modified silicone oils with special properties have appeared.
Silicone oil is generally colorless (or light yellow), odorless, non-toxic, and non-volatile liquid. Silicone oil is insoluble in water, methanol, glycol and -ethoxyethanol. It is miscible with benzene, dimethyl ether, methyl ethyl ketone, carbon tetrachloride or kerosene. It is slightly soluble in acetone, dioxane, ethanol and alcohol. . It has a small vapor pressure, a higher flash point and ignition point, and a lower freezing point. As the number of segments n is different, the molecular weight increases and the viscosity also increases. The solid silicone oil can have a variety of different viscosities, from 0.65 centistokes to millions of centistokes. If you want to make low-viscosity silicone oil, you can use acid clay as a catalyst and telomerize at 180°C, or use sulfuric acid as a catalyst to telomerize at a low temperature to produce high-viscosity silicone oil or viscous. Alkaline catalyst.
According to the chemical structure, silicone oil is divided into methyl silicone oil, ethyl silicone oil, phenyl silicone oil, methyl hydrogen silicone oil, methyl phenyl silicone oil, methyl chlorophenyl silicone oil, methyl ethoxy silicone oil, and methyl trifluoropropane. Base silicone oil, methyl vinyl silicone oil, methyl hydroxy silicone oil, ethyl hydrogen silicone oil, hydroxy hydrogen silicone oil, cyanide silicone oil, etc.; from the point of use, there are damping silicone oil, diffusion pump silicone oil, hydraulic oil, insulating oil, Heat transfer oil, brake oil, etc.
Silicone oil has excellent heat resistance, electrical insulation, weather resistance, hydrophobicity, physiological inertia and small surface tension. In addition, it also has a low viscosity-temperature coefficient and high compression resistance). Some varieties also have radiation resistance. Performance.
Silicone oil products and applications
Silicone oil has many special properties, such as low temperature viscosity coefficient, high and low temperature resistance, oxidation resistance, high flash point, low volatility, good insulation, low surface tension, non-corrosion to metals, non-toxic, etc. Because of these characteristics, silicone oil has excellent effects in many applications. Among various silicone oils, methyl silicone oil is the most widely used and is the most important variety in silicone oil, followed by methyl phenyl silicone oil. Various functional silicone oils and modified silicone oils are mainly used for special purposes.
Properties: colorless, odorless, non-toxic, non-volatile liquid.
Uses: There are a variety of different viscosities. It has higher heat resistance, water resistance, electrical insulation and lower surface tension. It is often used as high-grade lubricating oil, anti-vibration oil, insulating oil, defoaming agent, release agent, polishing agent and vacuum diffusion pump oil. Methyl silicone oil is the most commonly used. In addition, there are ethyl silicone oil, methyl phenyl silicone oil, nitrile-containing silicone oil and so on.
Preparation or source: an oily substance obtained by hydrolysis and polycondensation of difunctional and monofunctional organosilicon monomers.
