Product Description

Product Description

Polyethylene Glycol PEG ,It is non-toxic, non irritating, slightly bitter in taste, has good water solubility, and has good compatibility with many organic
components. They have excellent lubricity, moisture retention, dispersibility, adhesives, antistatic agents and softeners, and are widely used in cosmetics, pharmaceuticals, chemical fibers, rubber, plastics, paper making, paint, electroplating, pesticides,metal processing, food processing and other industries.

• Structure: PEG consists of repeating ethylene glycol units terminated by hydroxyl (-OH) groups, which can be modified for specific applications.
• Solubility: Highly soluble in water and many organic solvents due to the formation of hydrogen bonds between its ether (-O-) groups and water molecules.
• Non-Toxic and Non-Irritating: Low molecular weight PEGs are generally considered safe for human use. They are non-volatile, non-immunogenic, and easily excreted by the human body, making them suitable for medical and consumer applications.

Product Application

1. Pharmaceutical Industry

• Drug Formulation: As a pharmaceutical excipient, PEG serves as a solvent, emulsifier, and stabilizer. For example, PEG 400 enhances the solubility of poorly water-soluble drugs in liquid formulations.
• PEGylation: The process of attaching PEG chains to drugs (e.g., proteins, antibodies) extends their circulation time in the bloodstream, reduces immunogenicity, and minimizes degradation. This technology has been pivotal in developing long-acting medications, such as PEGylated for treating hepatitis C.
• Medical Devices: PEG coatings on catheters and stents improve biocompatibility by reducing protein adsorption and preventing blood clot formation.

2. Cosmetics and Personal Care

• Moisturizer and Emollient: In skincare products, low molecular weight PEGs (e.g., PEG 400) attract and retain moisture, enhancing skin hydration.
• Surfactant: PEG-based surfactants are used in shampoos, body washes, and toothpaste for their gentle cleansing properties and ability to reduce surface tension.

3. Food Industry

• Food Additive: Approved as a food-grade substance by regulatory bodies like the FDA, PEG functions as a lubricant, anti-sticking agent, and dispersant in food processing. For instance, it prevents sugar crystallization in confectionery and improves the texture of chewing gum.

4. Industrial Applications

• Lubricants and Coolants: In machinery, PEGs act as lubricants due to their high viscosity and thermal stability.
• Textile and Dyeing: Used as a dye carrier and leveling agent, PEG ensures uniform dye distribution on fabrics.
• Polymer Synthesis: As a raw material in the production of polyurethanes, PEG contributes to the flexibility and durability of plastics, adhesives, and coatings.

5. Biomedical Research

• Cell Fusion: High molecular weight PEGs facilitate cell membrane fusion, a crucial technique in creating hybridoma cells for monoclonal antibody production.
• Hydrogel Formation: Cross-linked PEG hydrogels are widely used in tissue engineering, drug delivery systems, and wound dressings due to their biocompatibility and tunable mechanical properties.
