Product introduction

Polyethylene glycol(PEG), also known as polyethylene oxide (PEO) or polyoxyethylene (POE), refers to an oligomer or polymer of ethylene oxide. Depending on the molecular weight, polyethylene glycol can be a liquid or a low-melting solid. Due to the influence of chain length, polyethylene glycols of different molecular weights often have different physical properties and applications, but most polyethylene glycols have similar chemical properties. Those with a relative molecular mass between 700 and 900 are semi-solid, and those with a relative molecular mass of 1,000 and above are light white waxy solids or flake-like paraffin or flowing powder.

Product specification

Product application

Polyethylene glycol has excellent lubricity, moisturizing and dispersing properties, and can be used as a softener and antistatic agent. It is widely used in cosmetics, pharmaceuticals, chemical fibers, rubber, plastics, papermaking, paints, electroplating, pesticides, metal processing and food processing. It has a wide range of applications in other industries.

PEG400 is a liquid. Because it is stable and not easy to deteriorate, it is most suitable for soft capsules. It is widely used in liquid preparations (such as oral liquids, etc.) and is a good solvent and thickener. PEG4000, PEG6000, and PEG8000 can be used to make tablets, pills, suppositories, film coatings, etc. During the tableting process, PEG can not only improve the tablet's ability to release drugs, but also has good plasticity. It can make the surface of the tablet shiny and smooth, not easily damaged, and can also prevent sugar-coated tablets from sticking to each other.

Polyethylene glycol can be used to modify drug proteins, protect drug molecules, and extend their half-life. Polyethylene glycol molecules can change the biomembrane structure of various types of cells, causing the lipid molecules of the plasma membrane to evacuate and reorganize at the contact point between the two cells, thereby causing the cells to fuse, forming hybrid cells, and obtaining some special hybrid plants.

Polyethylene glycol is also a food additive and is often used for coating candies and chocolate products. It can be used as a coating agent in food, and can also be used as a dispersant, binder, plasticizer, coating agent, lubricant, carrier solvent and flavor auxiliary.

Packaging & Storage

The chemical properties of polyethylene glycol are stable in the air and in solution, but those with a molecular weight below 2000 are easily hygroscopic. Not suitable for microbial growth and not prone to rancidity.

Polyethylene glycoland its aqueous solution can be sterilized by autoclaving, filtration or gamma rays. If solid state is sterilized by dry heat at 150°C for 1 hour, oxidation may be induced and degradation may occur.

It should be kept in a cool, dry place and stored in an airtight container. Liquid grade polyethylene glycol can be stored in stainless steel, aluminum, or glass containers.
