Long chain alkyl aryl silicone oil has lipophilicity and lubricity, and can be used as brightening agent, hydrophobic agent, slippery agent, lubricant and so on.

Different applications have different requirements on the structure of long chain alkyl aryl silicone oil, there are two main synthesis methods, one is methyl hydrochlorosilane and alpha olefin through siloaddition reaction, methyl long chain alkyl chlorosilane, then hydrolyzed condensation, and finally copolymerization.

The other is to start from methyl hydrogen-containing silicone oil, and directly carry out the hydrosilylation reaction with alpha olefin.

Features and Uses:

1. Lubricants
Long chain alkyl aryl silicone oil can improve the extreme pressure lubricity of common silicone oil. Special oils of high quality and high value can be obtained by adding a small amount of long chain alkyl aryl silicone oil to mineral oil, and long chain alkyl aryl silicone oil has good adsorption and excellent lubricity to metal materials. In addition, long chain alkyl aryl silicone oil can also be used as a base oil of high lubricity silicone grease, used in the lubrication of small machinery, plastic gears, rolling systems.

2. Cosmetics
Long chain alkyl aryl silicone oil is widely used in high-grade head oil, hair conditioner, lipstick, lipstick, etc., can be used as bright additives, hydrophobic agents, lubricants, slippery agents, etc., can give cosmetics excellent skin care, hydrophobic permeability, antioxidant, UV protection, softness, smoothness, anti-viscosity, etc., the properties are much better than the usual dimethyl silicone oil and phenyl silicone oil.

3. Field of defoamer
Long chain alkyl aryl silicone oil defoamer can be used in fermentation, food processing, medical, textile, petroleum, synthetic rubber and resin, paint and ink and other fields. Because of its good affinity to organic materials, the long chain alkyl aryl silicone oil defoamer will not affect the post-processing performance of the product; However, the surface tension increases with the increase of the carbon chain, the defoaming performance decreases, and the printability increases, so it is very important to choose the right carbon chain length.
