Long chain alkyl aryl silicone oil has lipophilicity and lubricity, and can be used as a brightening agent, hydrophobic agent, smoothing agent, lubricant, etc.

Different applications have different requirements for the structure of long-chain alkyl aryl silicone oil. Currently, there are mainly two synthesis methods, one is methyl hydrochlorosilane and the other is methyl hydrochlorosilane α Olefins are produced by hydrosilylation reaction to form methyl long-chain alkyl chlorosilane, which is then hydrolyzed and condensed, and finally subjected to copolymerization reaction.

Another method is to start with methyl silicone oil containing hydrogen, which is directly mixed with α Olefins undergo hydrosilylation reaction.

Characteristics and usage:

1. Lubricant field
Long chain alkyl aryl silicone oil can improve the extreme pressure lubricity of general silicone oil. Adding a small amount of long-chain alkyl aryl silicone oil to mineral oil can obtain high-quality and high-value special oil products, and long-chain alkyl aryl silicone oil has good adsorption and lubrication properties on metal materials. In addition, long-chain alkyl aryl silicone oil can also be used as a base oil for high lubricity silicone grease, for lubrication in small machinery, plastic gears, and rolling systems.

2. Cosmetics field
Long chain alkyl aryl silicone oil is widely used in high-end hair oils, hair conditioners, lipsticks, lipstick, etc. It can be used as brightening additives, hydrophobic agents, lubricants, smoothing agents, etc. It can give cosmetics excellent skin care, hydrophobic breathability, oxidation resistance, UV protection, softness, smoothness, anti stickiness, etc. All properties are greatly superior to ordinary dimethyl silicone oil and phenyl silicone oil.

3. Defoamer field
Long chain alkyl aryl silicone oil defoamers can be applied in fields such as fermentation, food processing, medical, textile, petroleum, synthetic rubber and resin, coatings, and inks. Due to its good affinity for organic materials, long chain alkyl aryl silicone oil defoamers will not affect the post processing performance of the product; However, its surface tension increases with the increase of carbon chains, leading to a decrease in defoaming performance and an increase in printability. Therefore, it is important to choose an appropriate carbon chain length.
