Silicone oil is a polyorganosiloxane with chain structure of different degrees of polymerization. It is obtained by hydrolyzing dimethyl dichlorosilane with water to obtain the initial polycondensation ring body, and the ring body is cracked,

The low ring body is obtained by rectification, and then the ring body, head agent, and catalyst are put together to telomerize to obtain a mixture of various degrees of polymerization, and the low ring body is removed by vacuum distillation.

Silicone oil can be obtained by boiling.

The most commonly used silicone oil, organic groups are all methyl, called Shenji silicone oil. Organic groups can also use other organic groups to replace some methyl groups to improve

Introduce a certain performance of silicone oil and apply to various purposes. Common other groups include hydrogen, ethyl, phenyl, chlorophenyl, trifluoropropyl, and the like. In recent years, organic

Modified silicone oil has developed rapidly, and many organically modified silicone oils with special properties have emerged.

Silicone oil is generally a colorless (or light yellow), odorless, non-toxic, non-volatile liquid. Silicone oils are insoluble in water, methanol, glycols and -ethoxyethanol and can

It is miscible with benzene, dimethyl ether, methyl ethyl ketone, carbon tetrachloride or kerosene, slightly soluble in acetone, dioxane, ethanol and alcohol. It has a small vapor pressure, high

Flash point and fire point, lower freezing point. With the difference of the number of segments n, the molecular weight increases and the viscosity also increases, so the silicone oil can have various viscosities, from

0.65 centistokes up to millions of centistokes. If low-viscosity silicone oil is to be obtained, acid clay can be used as a catalyst, and telomerization is carried out at a temperature of 180°C, or

Sulfuric acid is used as a catalyst to carry out telomerization at low temperature, and a basic catalyst can be used to produce high-viscosity silicone oil or sticky matter.

According to the chemical structure, silicone oil can be divided into methyl silicone oil, ethyl silicone oil, phenyl silicone oil, methyl hydrogen-containing silicone oil, methyl phenyl silicone oil, methyl chlorophenyl silicone oil, methyl

Ethoxylated silicone oil, methyl trifluoropropyl silicone oil, methyl vinyl silicone oil, methyl hydroxy silicone oil, ethyl hydrogen silicone oil, hydroxyl hydrogen silicone oil, cyanide silicone oil, etc.; from

In terms of uses, 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 inertness and small surface tension, in addition to low viscosity-temperature coefficient,

Higher compression resistance) Some varieties also have radiation resistance.



Silicone oil can be well used in the production of cosmetics to improve the performance of cosmetics. Silicone oil has a combination of low surface tension and viscosity, which can make other components of cosmetics easy to spread into a thin film on the skin without stickiness. The detackification performance of silicone oil makes it compatible with vaseline, paraffin wax, beeswax, lanolin, etc. It can be combined to obtain non-sticky products. Volatile silicone oil can give cosmetics fast-drying, smooth, anti-fouling and good gloss. As a cosmetic carrier, it can quickly dissipate and make other cosmetic components into a uniformly distributed film. It is very important in eye beauty products and nail polish. In hair care products, silicone oil can increase the luster of hair, and at the same time it can play a role in shaping and preventing hair from sticking together. In shampoo, silicone oil can make hair Hair is easy to comb. In skin care products, the hydrophobic film formed by silicone oil can prevent other components from being washed away by water, and keep the skin in a normal breathable state. At present, silicone oil has become an important component or auxiliary agent of many cosmetics
