Hydrogenated castor is a derivative of castor, with a high melting point and stable performance. It is used widely in cosmetics.

The following is a list of the most recent articles about  PEG-n hydrogenated castor oil：

Chemical structure: Hydrogenated castor oil is mainly obtained by hydrogenation of castor oil. Its chemical structure is similar to castor oil, but the carbon-carbon double bond is reduced, making hydrogenated castor oil chemically more stable.

Physical state: Hydrogenated castor oil is usually a transparent or yellowish liquid with a relatively high viscosity, which allows it to act as a binder or thickener in some applications.

Stability: Due to its hydrogenation process, hydrogenated castor oil has good thermal and chemical stability and is not easy to oxidize or undergo other chemical reactions. This allows it to maintain good properties under high-temperature conditions or long-term storage.

Solubility: Hydrogenated castor oil can be well dissolved in many organic solvents, such as alcohols, esters and hydrocarbons. 

Lubricity: hydrogenated castor oil has good lubricating properties and can be used as a lubricant in mechanical, electronic and metallurgical fields. Its high viscosity characteristics give it a superior lubrication effect in some occasions.

Physiological properties: Although hydrogenated castor oil is similar to castor oil in many ways, the hydrogenation process removes the carbon-carbon double bonds that can cause allergic reactions, making hydrogenated castor oil much safer to use. However, because it is derived from castor oil, some people may still have an allergic reaction to it, and proper skin testing should be done when using it.

Toxicity: Hydrogenated castor oil is less toxic than some compounds. However, any chemical can be toxic, so you should follow safety guidelines and take appropriate protective measures when using hydrogenated castor oil.

Environmental effects: Due to its possible biodegradability, the long-term environmental effects of hydrogenated castor oil are unclear. Their residues can impact the environment in some applications, such as coatings and adhesives. Therefore, its environmental impact should be considered when used, and appropriate environmental protection measures should be taken.

Applications of PEGn hydrogenated castor oils  :

Cosmetics industry: Because hydrogenated castor oil has good moisturizing and moisturizing properties, it is often used in cosmetics, such as moisturizer, lipstick, nail polish and so on. It can help retain the skin's moisture, making the cosmetics' texture more delicate and better to use.

Pharmaceutical industry: Hydrogenated castor oil is mainly used in the pharmaceutical industry to make drug capsules and ointment substrates. Its chemical stability can protect the drug ingredients from adverse factors such as light, oxygen, and humidity and ensure the stability and effectiveness of the drug.

Food industry: Hydrogenated castor oil has high stability and can maintain stability in high temperatures and oxygen, so it is widely used in the food industry. It can be used as a food additive, such as a stabilizer, emulsifier, and thickener, for producing dairy products, sauces, chocolate, candy, and other foods.

Plastics industry: Hydrogenated castor oil can be used as a plasticizer to improve the processability and flexibility of plastics. For example, it can be added to polyvinyl chloride (PVC) to make the PVC material softer and easier to process and form.

Printing and ink industry: Hydrogenated castor oil is used as an additive in the printing and ink industry to improve the rheology and adhesion of inks. It can make the ink transfer better during the printing process and improve the quality and durability of the print.

Textile industry: Hydrogenated castor oil is used as a softener and antistatic agent in the textile industry. It can improve the fabric's feel, softness and antistatic properties, making the textile more comfortable and easy to care for.

Agriculture: Hydrogenated castor oil can be used as an insecticide and plant growth regulator. It can effectively control the propagation of pests and promote the growth and development of plants.

Commodity production: In producing soap, soap, detergent and other daily necessities, hydrogenated castor oil can be used as a foam stabilizer and wetting agent to help improve the quality and performance of the product. It can make the product gentler and easier to clean and enhance its durability.

Production Method of PEGn hydrogenated castor oils  :

Chemical hydrogenation

Chemical hydrogenation is the reaction of castor oil and hydrogen at high temperature and high pressure so that the unsaturated double bonds in the oil and hydrogen gas addition reaction saturate. The catalysts commonly used in this method are sulfuric acid or nickel Catalyst.

Sulfuric acid as a catalyst: Sulfuric acid in the hydrogenation process can promote the double bond in the oil and hydrogen to react. However, sulfuric acid, as a strong acid, is corrosive to the equipment and causes environmental pollution. In the hydrogenation process, the concentration and temperature of sulfuric acid greatly influence the hydrogenation effect. Too high or too low a concentration will affect the hydrogenation effect, and too high a temperature may lead to side reactions.

Nickel catalyst: To solve sulfuric acid's corrosion and pollution problems, people have developed a catalyst with nickel as the main component. Nickel catalysts can promote the reaction between hydrogen and double bonds in grease under certain conditions. Still, the preparation and recovery cost of nickel catalysts is high, and by-products may be produced in the hydrogenation process, which affects the hydrogenation effect.

Advantages: The advantage of chemical hydrogenation is that the reaction conditions are mild, can be carried out at room temperature and pressure, the hydrogenation effect is good, and high saturation hydrogenated oil can be obtained.

Disadvantages: The disadvantage of chemical hydrogenation is that the sulfuric acid or nickel catalyst used has certain pollution and safety problems, and the reaction conditions need to be strictly controlled during the production process to prevent the occurrence of side reactions. In addition, the cost of chemical hydrogenation is high, and the resulting hydrogenated grease may contain small amounts of unreacted catalyst residues.

Catalytic hydrogenation

Catalytic hydrogenation makes the unsaturated double bond in the oil and hydrogen gas addition reaction to saturate. The catalysts commonly used in this method are metal catalysts such as palladium or nickel.

Palladium catalyst: Palladium catalyst can effectively promote the reaction of hydrogen gas with double bonds in grease during catalytic hydrogenation. The mild reaction conditions can be carried out at low temperatures and pressure. The preparation method of palladium catalyst is also relatively simple and can be reused. However, the high price of palladium catalysts increases the production cost.

Nickel catalysts: Besides palladium catalysts, nickel catalysts can also catalyze hydrogenation processes. Nickel catalyst has high activity and can promote hydrogenation at low temperatures and pressures. However, nickel catalysts' preparation and recovery costs are high, and by-products may be produced during hydrogenation.

Advantages: The advantage of catalytic hydrogenation is that the catalyst used is environmentally friendly and does not cause pollution to the environment. At the same time, the reaction conditions of catalytic hydrogenation are mild and can be carried out under lower temperatures and pressure, which reduces energy consumption and side reactions. In addition, the production efficiency of catalytic hydrogenation is high, and the quality of hydrogenated oil obtained is better.

Disadvantages: The disadvantage of catalytic hydrogenation is the high cost of catalysts, especially palladium catalysts. This increases production costs and limits its application in some fields. At the same time, the reaction conditions should be strictly controlled in the catalytic hydrogenation process to prevent side reactions. In addition, the resulting hydrogenated grease may contain a small amount of unreacted catalyst residues.
