Physical property

Ethanol stearyl ethoxylate is a white or yellowish waxy substance with a slight odor. It is soluble in water and organic solvents and is solid or semi-solid at room temperature. Ethanol stearyl alcohol ethoxylate has a broad melting point range, generally between 40-60 ° C, maintaining good stability at different temperatures.

Chemical properties

Ethanol stearyl ethoxylate is a non-ionic surfactant with good chemical stability. It is not easily chemically reactive with other substances, so it remains stable in most chemical environments. In addition, ethanol stearyl alcohol ethoxy ester has good acid and alkaline resistance and can maintain stability at different pH values.

Application fields

Ethanol stearyl ethoxy ester has been widely used in many fields. First of all, in cosmetics, it is used as an emulsifier, thickener and stabilizer, which can improve the stability and use effect of the product. In addition, it is also used in textile, printing and dyeing, leather and other industries, as a softening agent, antistatic agent and so on.

Security

Ethanol stearyl ethoxylate is safe under normal conditions of use. However, its irritating nature may have a slightly irritating effect on the eyes and skin. Therefore, care should be taken to avoid direct contact with the eyes and skin during use and follow the relevant safe operating procedures.

Applications of Cetostearyl Alcohol Ethoxylate  :

Washing products: ethanol stearyl ethoxy ester plays a vital role in washing products. It has excellent decontamination ability and can effectively remove oil stains on clothing. In addition, it also has low irritant and mild properties and is friendly to the skin, so it is widely used in washing products such as washing powder, washing liquid and soap.

Cosmetics: Ethanol stearyl ethoxylate is also widely used in cosmetics. It cleans the skin and retains moisture while promoting the absorption of nutrients. In cosmetics such as shampoos, body washes, and body creams, ethoxylate can provide a good user experience.

Paints and coatings: Ethanol stearyl ethoxy ester is also used in paints and coatings. It can improve the wettability and adhesion of the coating, thereby improving its construction performance and drying speed. This is significant for improving the performance of coatings and paints and increasing production efficiency.

Other fields:  In pesticides, it can improve the wettability and dispersion of pesticides, thus improving the control effect. In the petroleum industry, it can be used as an oilfield chemical agent to improve oil recovery and production efficiency. Textile printing and dyeing can improve dyes' wettability and dispersion, thereby improving dyeing quality and production efficiency.

Production Method of Cetostearyl Alcohol Ethoxylate  :

Esterification reaction

Esterification is the first step in the production of ethanol stearyl ethoxy ester. In this reaction, stearic acid (C18H36O2) and ethanol (C2H5OH) are esterified under the action of a catalyst to produce ethyl stearate (C20H38O2).

Raw material preparation: First, you must prepare stearic acid and ethanol. Stearic acid is usually provided in solid or liquid form, while ethanol is in liquid form. In addition, preparing a catalyst, such as sulfuric acid or p-toluene sulfonic acid, is necessary.

Reaction conditions: Esterification is usually carried out under heating conditions, and the temperature is generally between 100-150 ° C. The reaction process needs to be stirred continuously to promote the reaction.

Catalyst: The catalyst plays a vital role in the esterification reaction. Common catalysts are sulfuric acid, p-toluene sulfonic acid and so on. These catalysts can promote esterification between stearic acid and ethanol.

Reaction time: The esterification reaction time is usually between a few hours and ten hours, depending on the reaction conditions and the type of catalyst.

Product separation: After the end of the reaction, the generated ethyl stearate is separated from the reaction system. This is usually achieved by methods such as distillation or crystallization.

Ethoxylation reaction

Ethoxylation is the second step in producing ethanol stearyl alcohol ethoxy ester. In this reaction, ethyl stearate and ethylene oxide (C2H4O) are ethoxylated under a catalyst to produce ethanol stearyl alcohol ethoxy ester.

Raw material preparation: Ethyl stearate and ethylene oxide need to be prepared. Ethylene oxide is a flammable and explosive chemical, so special attention to safe handling is required.

Reaction conditions: The ethoxylation reaction is usually carried out under heating conditions, and the temperature is generally between 100-150 ° C. The reaction process needs to be stirred continuously to promote the reaction.

Reaction time: The ethoxylation reaction time is usually between a few hours and ten hours, depending on the reaction conditions and the type of catalyst.

Product separation: After the end of the reaction, the generated ethanol stearyl alcohol ethoxylate is separated from the reaction system. This is usually achieved by methods such as distillation or crystallization.
