Introduction to Polyethylene Glycol 4000

Polyethylene glycol 4000 is a mixture formed by the condensation of ethylene oxide and water, with the chemical formula HO (CH2CH2O) nH.

It is usually a white waxy solid or granular powder, belonging to a type of organic matter. Polyethylene glycol 4000 is soluble in water and many polar solvents such as acetone, ethanol, and chlorinated solvents. Its aqueous solution is stable at room temperature and has a wide range of chemical compatibility, making it an excellent solvent and solubilizer, widely used in industrial, medical, cosmetic and other fields.

Polyethylene glycol 4000 is mainly used as a matrix in industrial production to regulate viscosity and melting point. It can also be used as a lubricant, coolant, dispersant, emulsifier, antistatic agent, etc.

Specifically, the application of polyethylene glycol 4000 in various industrial fields includes: rubber industry: as an additive, it increases the lubricity and plasticity of rubber products, reduces power consumption during processing, and extends the service life of rubber products.

Metal processing industry: used as lubricants and coolants to help reduce friction and heat during the processing.

Pesticide and pigment industry: used as dispersants and emulsifiers to help chemicals disperse and mix better.

Textile industry: used as anti-static agents and lubricants to reduce static electricity accumulation and improve the production efficiency and quality of textiles.

Pharmaceutical industry: used as an excipient in the preparation of suppositories, pastes, etc., with good moisturizing properties and stability.

In addition, polyethylene glycol 4000 also has some special physical and chemical properties, such as being a white waxy solid, easily soluble in water or ethanol, and insoluble in ether. These properties make it perform well in various industrial applications.

The application of polyethylene glycol 4000 in cosmetics is mainly as a moisturizing agent and emulsion stabilizer, which can improve the application feeling and stability of cosmetics. Polyethylene glycol 4000 has good water solubility and emulsifying properties, which can enhance the moisturizing effect of cosmetics and maintain the uniformity and stability of the product.

The specific mechanism of action of polyethylene glycol 4000 in cosmetics is through its excellent solubility and emulsifying properties, which can absorb and retain moisture, keeping the skin moist and smooth. As an efficient moisturizer, it can enhance the application and user experience of cosmetics, while helping to maintain the skin's water oil balance, preventing dryness and tightness.

In addition, polyethylene glycol 4000 has good biocompatibility and degradability, is non-toxic and non irritating to the human body, and is suitable for long-term use. This makes it widely used in various skin care and cosmetics products in the cosmetics industry, such as face cream, lotion, essence, etc., to provide consumers with safe and effective skin care solutions.
