| Poly(ethylene glycol) Usage And Synthesis |
| Chemical properties | Polyethylene glycol is a polymer which is hydrolyzed by ethylene oxide. It has no toxicity and irritation. It is widely used in various pharmaceutical preparations. The toxicity of low molecular weight polyethylene glycol is relatively large. In general, the toxicity of diols is very low. Topical application of polyethylene glycol, especially mucosal drug, can cause irritant pain. In topical lotion, this product can increase the flexibility of the skin, and has a similar moisturizing effect with glycerin. Diarrhoea can occur in large doses of oral administration. In injection, the maximum polyethylene glycol 300 concentration is about 30% (V/V). Hemolysis could occur when the concentration is more than 40% (V/V). |
| Application in biomedicine | Polyethylene glycol is also known as polyoxirane (PEO). It is a linear polyether obtained by ring opening polymerization of ethylene oxide. The main uses in the field of biomedicine are as follows:
|
| Chemical Properties | White waxy crystalline flakes |
| Uses | Used in conjunction with carbon black to form a conductive composite.1 Polymer nanospheres of poly(ethylene glycol) were used for drug delivery.2 |
| Uses | Poly(ethylene Glycol) molecules of approximately 2000 monomers. Poly(ethylene Glycol) is used in various applications from industrial chemistry to biological chemistry. Recent research has shown PEG m aintains the ability to aid the spinal cord injury recovery process, helping the nerve impulse conduction process in animals. In rats, it has been shown to aid in the repair of severed sciatic axons, helping with nerve damage recovery. It is industrially produced as a lubricating substance for various surfaces to reduce friction. PEG is also used in the preparation of vesicle transport systems in with application towards diagnostic procedures or drug delivery methods. |
| Uses | H2 histamine receptor antagonist, anti-ulcer agent |
| Uses | nonionic emulsifier |
| Uses | A polymer used to precipitate proteins, viruses, DNA and RNA |
| General Description | Clear colorless viscous liquid. |
| Air & Water Reactions | Water soluble. |
| Reactivity Profile | Poly(ethylene glycol) is heat-stable and inert to many chemical agents; Poly(ethylene glycol) will not hydrolyze or deteriorate under normal conditions. Poly(ethylene glycol) has a solvent action on some plastics. |
| Fire Hazard | Poly(ethylene glycol) is combustible. |
