Surface activity: Polyoxyethylene castor oil has good surface activity and can form a thin film on the surface of the liquid, reducing the surface tension and thereby improving the wettability and permeability of the liquid. This property makes it widely used in cleaning agents, wetting agents, emulsifiers and other fields.

Viscosity: The viscosity of polyoxyethylene castor oil is relatively low, and the fluidity is good, which is convenient to add and use in production. At the same time, its viscosity changes less with temperature, and the use effect is more stable.

Stability: Polyoxyethylene castor oil has good chemical stability and oxidation resistance, is not easy to decompose and deteriorate, and can be used in different environments for a long time. In addition, it also has good high-temperature resistance, corrosion resistance, radiation resistance, and other properties.

Physiological safety: Compared with some chemically synthesized surfactants, polyoxyethylene castor oil has better physiological safety, less irritation to the skin and eyes, and does not easily cause allergic reactions. Therefore, it is widely used in direct contact with the human body, such as cosmetics and cleaning agents.

Environmental protection: polyoxyethylene castor oil does not produce harmful substances in the production process, is easy to biodegrade after use and is friendly to the environment. This makes it of great concern in the context of green chemistry and sustainable development.

Production Method of Castor oil Polyoxyethylene  :

Chemical method

The chemical method is the most common method for preparing polyoxyethylene castor oil. Polyoxyethylene castor oil is produced by the additional reaction of castor oil and ethylene oxide under a catalyst.

Reaction principle: The reaction principle of the chemical method is that the unsaturated advanced fatty acids in castor oil and ethylene oxide are added under the action of the catalyst to produce polyoxyethylene castor oil. In the reaction process, ethylene oxide opens the ring under the action of the catalyst and reacts with unsaturated double bonds in castor oil to produce polyoxyethylene castor oil.

Catalyst: In chemical methods, the choice of catalyst has an important impact on the quality and yield of the product. Commonly used catalysts include sodium hydroxide, potassium hydroxide, sulfuric acid, etc. These catalysts can promote the ring-opening addition reaction of ethylene oxide and improve the yield and quality of the product.

Reaction conditions: The reaction conditions in the chemical process also have an important effect on the quality and yield of the product. Therefore, sufficient experiments and optimization are required to determine the optimal reaction conditions during the production process.

Advantages and disadvantages: The chemical method also has some disadvantages, such as the need to use catalysts by-products, high energy consumption, and the need to control the reaction conditions strictly. In addition, the chemical production process may produce wastewater and waste residue, which need environmentally friendly treatment.

Enzyme catalytic method

Enzymatic catalysis is a bioengineering technique used to prepare polyoxyethylene castor oil. The addition reaction is carried out under mild conditions using enzymes as catalysts.

Reaction principle: The reaction principle of the enzyme catalysis method is to use enzymes as catalysts to catalyze the addition reaction of castor oil and ethylene oxide. The highly specific and active enzyme can perform addition reactions at relatively low temperatures and pressures to produce polyoxyethylene castor oil.

Enzyme selection: In enzyme catalysis, the selection of enzymes has a key influence on the rate of addition reaction and product quality. Different enzymes have different catalytic activity and selectivity, and it is necessary to select suitable enzymes according to specific reaction conditions and product requirements.

Reaction conditions: The reaction conditions of the enzyme-catalyzed method are usually mild and can be carried out at lower temperatures and pressures. However, enzyme catalysis also needs to control certain reaction conditions, such as material ratio, pH value, temperature, etc., to ensure the activity and selectivity of the enzyme.

Advantages and disadvantages: The advantages of enzyme catalysis are environmentally friendly, mild conditions and high selectivity. The enzyme catalysis method can reduce energy consumption and wastewater generation, which meets the requirements of sustainable development. However, enzyme catalysis also has some disadvantages, such as the high cost of enzymes and relatively low production efficiency. In addition, the enzyme-catalyzed method has high requirements for the purity of substrates and products. It requires strict control of the quality of raw materials and impurities in the reaction process.
