In the process of continuous evolution of organic silicon materials towards high-performance and functionalization, introducing specific functional groups through molecular structure design to expand the performance boundaries has become the core path of industry technological innovation. The product we have launched, long-chain alkyl silicone oil, is a new type of modified polyorganosiloxane generated by replacing and grafting some methyl groups of traditional polydimethylsiloxane with long-chain alkyl groups. With its comprehensive advantages of both the basic properties of silicone oil and the unique functions of alkyl groups, as well as being more superior in smoothness, wear resistance, organic compatibility, and printable properties compared to traditional dimethyl silicone oil, it demonstrates significant industrial application value in numerous fields such as cosmetics, release agents, lubricants, coating additives, and plastic modification, providing high-performance functional additives for customers in various industries.


I. Core Structural Characteristics and Physical Properties


The long-chain alkyl silicone oil product is a new type of modified polyorganosiloxane generated by replacing and grafting some methyl groups of traditional polydimethylsiloxane with long-chain alkyl groups. In this structure, the introduction of long-chain alkyl groups breaks the single chemical environment of traditional dimethyl silicone oil, bringing a new performance dimension to the material. The product has a transparent oily liquid appearance, is colorless and odorless, with a viscosity range of 100 to 5,000 centipoises, and can provide various viscosity specifications according to different application requirements. Its specific gravity is between 0.850 and 1.0, and it is completely miscible with mineral oil.


II. Core Performance Advantages


Compared to traditional dimethyl silicone oil, the long-chain alkyl silicone oil product demonstrates significant performance improvements in the following aspects:


Excellent smoothness and wear resistance. The introduction of long-chain alkyl groups gives the product a lower friction coefficient and better anti-wear performance, performing particularly well in lubricant and lubricating grease formulations. It has excellent lubricating effects on metals with poor lubricity such as stainless steel, titanium steel, aluminum, zinc, and copper.


Good compatibility with mineral oil and organic materials. Traditional dimethyl silicone oil has limited compatibility with mineral oil and other organic materials, while the introduction of long-chain alkyl groups significantly improves the product's hydrophilicity, enabling it to be mixed with mineral oil in any proportion. When used in combination with other oil agents, the stability of the resulting product is significantly better than when using dimethyl silicone oil.


Excellent printable properties and compatibility with subsequent processing. When used as a release agent or isolation agent, the product generally does not require cleaning before direct secondary processing such as printing, coloring, and bonding, while traditional dimethyl silicone oil usually requires cleaning before these processes, effectively simplifying the production process and reducing production costs.


Applicability as an internal release agent and internal dispersant. Due to its good compatibility with organic materials, it can be used as an internal release agent for rubber, plastic, synthetic resin, etc., and as an internal dispersant for various oil-phase or solid-phase organic materials such as colorants and other additives.


Good moisturizing, smoothing, and anti-drying crack functions. The introduction of long-chain alkyl groups enables the product to provide better moisturizing effects and smoothness to the skin and hair in cosmetic formulations.


III. Wide Application Areas


The long-chain alkyl silicone oil product, with its multi-functional performance combination, can play a key role in the following application areas:


1. Cosmetics and personal care products. The product is used as a lubricant and conditioner in shampoos, creams, hair conditioners, and skin care lotions, maintaining skin moisture, reducing dryness symptoms, maintaining skin softness, and improving the combing and glossiness of hair.


2. Release agent application. It is suitable for the release and demolding of plastics, rubber, and metal products, especially for the demolding of polyurethane products. It can be used as an external release agent or as an internal release agent in plastics, synthetic resins, etc. The demolded products can undergo secondary processing such as printing, coloring, and bonding without additional cleaning. III. Base oil or main components of lubricating oil and grease. The product has excellent lubrication and wear resistance properties, and is suitable for lubrication between stainless steel and titanium steel, as well as lubrication of aluminum machines and other difficult-to-lubricate metal friction pairs. No additional boundary lubrication additives are required to achieve excellent lubrication effects.


IV. Additives for coatings, inks and paints. A small amount is added to paints, inks or coatings, which can significantly improve the gloss of the product and has an anti-bubbling effect, while improving the dispersion, leveling and wear resistance of pigments.


V. Plastic and rubber modifiers. The product can be used as a plastic additive to improve the boundary lubrication characteristics of plastic products and enhance the processing lubrication and surface quality of the products.


VI. Lubricants for fibers and yarns. When mixed with paraffin, it can be used as a lubricant for fibers and yarns and a processing aid for melt spinning.


VII. Oil dewaxing agents and hydrophobic agents. A small amount of the product added to the crude oil can effectively lower its freezing point, and can also be used as a hydrophobic agent.


IV. Usage suggestions and dosage reference


Depending on the application industry, the addition amount when used as an additive is generally selected between 0.2% and 5%. When used as an external demolding agent, generally, the product is emulsified or diluted to a concentration of 2.5% to 10% and sprayed or brushed onto the mold surface. Since the product is a series of products, the number of grafted long-chain alkyl groups varies, resulting in significant performance differences. Users should pay attention to correctly selecting according to the specific application scenarios.


V. Packaging specifications and storage conditions


The product is packaged in polyethylene plastic drums, with specifications ranging from 5 kilograms to 50 kilograms, which can be selected according to customer requirements. It is transported and stored as non-hazardous goods. If stored for an extended period, there is a tendency for viscosity to increase. It is prohibited from contact with strong acids and strong alkalis. It should be stored in a ventilated and dry place. The storage period is half a year at room temperature. Beyond the expiration date, it can be re-inspected and if qualified, it can still be used.


VI. Quality guarantee and industry application value


The long-chain alkyl silicone oil in the product has established a strict quality control system during the production process. Key indicators such as appearance, viscosity, specific gravity and solubility are tested throughout the process to ensure consistency and reliability between batches. As the demand for multifunctional additives with lubrication, compatibility and printable properties continues to grow in industries such as cosmetics, demolding agents, lubricants, plastic modification and coatings, the long-chain alkyl silicone oil of this product, with its unique performance advantages conferred by the long-chain alkyl group, is becoming an important solution for customers in various fields in the selection of functional additives, providing strong support for promoting the product quality improvement and process optimization in the downstream industry.
