Polyglycol laurate CAS 141-20-8

It is a clear to pale yellow liquid that can be pressed into a solid.

Description of Polyglycol laurate :

First, polyethylene glycol laurate has good water solubility and can form a stable solution in water. This is because the polyethylene glycol chain has good hydrophilicity and can form hydrogen bonds with water molecules, thus obtaining good solubility in water. At the same time, adding laurate also enhanced the solubility of the whole molecule in water.

Secondly, polyethylene glycol laurate has excellent surface activity. Surfactants can accumulate at the interface and significantly reduce the interfacial tension. The laureate group in the polyethylene glycol laurate molecule has good lipophilicity. It can be well adsorbed on the oil-water interface, reducing the oil-water interfacial tension to a very low level to achieve effective removal of oil and dust. Therefore, polyethylene glycol laurate is widely used in detergents and cosmetics as the main surfactant component.

In addition, polyethylene glycol laurate also has good foaming properties. During the washing process, the foam is created to help separate the stain from the surface and suspend it in water, making it easy to rinse. The foaming properties of polyethylene glycol laurate are related to its molecular structure. The hydrophilic groups can combine with water molecules to form stable hydrogen bonds, while the oil hydrophilic groups can form effective foam walls. This structure allows polyethylene glycol laurate to produce a rich and stable foam at a lower concentration.

In addition, polyethylene glycol laurate also has a certain resistance to hard water. In hard water, polyethylene glycol laurate can effectively maintain its surface activity and foaming properties, and it is not easy to form hard water ion precipitates such as calcium and magnesium, so it has a wider range of use in practical applications. This is due to the special design of its molecular structure, which can avoid the interference of hard water ions through a certain arrangement.

 Technical Parameters of Polyglycol Laurate

Applications of Laurate of polyglycol  :

Detergent industry: Polyethylene glycol laurate is used as the main surfactant component in detergents, which can effectively remove various stains and dust. Its excellent surface activity and foaming properties give the detergent a good washing effect at a lower concentration. Through the synergistic action with other surfactants, polyethylene glycol laurate can significantly improve detergents' washing power and deconfouling ability and is widely used in clothing washing, household cleaning, and other fields.

Cosmetics industry: Polyethylene glycol laurate is mainly used in cosmetics to formulate creams, lotions, facial masks and other products. It can effectively reduce the interfacial tension of oil and water, improve the permeability and flexibility of the product, and make cosmetics more easily absorbed by the skin. At the same time, the foaming properties of polyethylene glycol laurate also make it widely used in foam cosmetics such as facial cleansers and shampoos. In addition, polyethylene glycol laurate also has certain antibacterial properties, helping to keep cosmetics hygienic and safe.

Food industry: Polyethylene glycol laurate is mainly used in food packaging and processing. It can improve the wettability and printing performance of the food surface, making food packaging more beautiful and easy to identify. Polyethylene glycol laurate is also widely used in dairy products, beverages, condiments and other fields.

Oil field and mining industry: In the oil field and mining industry, polyethylene glycol laurate can be used for enhanced oil recovery and flotation separation of minerals. Its properties of reducing the interfacial tension between oil and water help to improve oil recovery and reduce oil waste. At the same time, the foaming property of polyethylene glycol laurate also contributes to the flotation separation process of minerals and improves their recovery rate and purity.

Pharmaceutical industry: Polyethylene glycol laurate can be used in drug preparation and production processes in the pharmaceutical industry. It can be used as an auxiliary agent, such as a wetting agent, emulsifier, or solvator, to help dissolve, stabilize, and release drugs. In addition, polyethylene glycol laurate has certain antibacterial properties, which help maintain the hygiene and quality of pharmaceutical preparations.

Agricultural field: Polyethylene glycol laurate can formulate agricultural products such as pesticides and fertilizers. Its properties of reducing the interfacial tension of oil and water help to improve the wettability and adhesion of the pesticide, making it easier for the pesticide to adhere to the plant's surface and exert its efficacy. At the same time, polyethylene glycol laurate also has certain permeability and solubilization properties, which help improve fertilizer's solubility and absorption efficiency.

Production Method of Laurate of polyglycol  :

Raw material preparation

Polyethylene glycol lauric acid includes polyethylene glycol, lauric acid, catalyst, deionized water, etc. Among them, polyethylene glycol is the basic chain structure, lauric acid is the lipophilic group, and the catalyst accelerates the reaction process.

Synthesis steps

Esterification reaction: Lauric acid and polyethylene glycol are esterified under the action of a catalyst to produce polyethylene glycol laurate. This step is the key to the entire production process, and it is necessary to control the conditions of the esterification reaction, such as temperature, pressure, reaction time, etc., to ensure the complete esterification reaction and the stability of the product.

Salinization reaction: Polyethylene glycol laurate reacts with an appropriate amount of inorganic salt (such as sodium chloride, sodium sulfate, etc.) to produce polyethylene glycol laurate. This step aims to improve the product's water solubility and surface activity through the salinization reaction.

Washing and refining: After the above reaction steps, the products obtained may contain impurities such as unreacted raw materials and catalysts. Therefore, it is necessary to carry out washing and refining steps to remove impurities and obtain pure polyethylene glycol laurate.

Drying and packaging: The resulting polyethylene glycol laurate is dried and packaged for subsequent application. When drying, focus on controlling the temperature and humidity to avoid degradation or caking of polyethylene glycol laurate.
