Product description
Polyethylene glycol (PEG) is a polymer made of ethylene oxide. Almost any MW, from 200 to 60000. 400 to 12,000 are the most common, and 400 are the most common liquids and 2,500 solids. (Any room that exceeds 800 to 1,000 is solid at room temperature) at any reasonable level non-toxic. It has a non-polarity and a large number of hydroxyl functional groups. This makes it well enough to keep things soluble in oil. There are a lot of reasons for compatibility reasons. Can also be used as a carless car, not oil.
Disadvantages include high viscosity and thermoplastic tendencies to become more pronounced at higher MWs. But also has the mechanical properties (surface tension) that separates it from the oil. This may become less pronounced at higher MWs, but I do not have the opportunity to test at this time.
Technical Information: CAS # 25322-68-3, MW MW is relatively low moisture. Density: Range: 1.1 to 1.2 (increased with molecular weight) Melting point: As the molecular weight increases, the melting point increases: PEG 400 = 4-8 ° C (39-46 ° F) PEG 600 = 20-25 ° C (68 -77 ° F) PEG1500 = 44 -48 ° C (111-118 ° F)

Product application
Polyethylene glycol 400 is suitable for most soft capsules. Polyethylene glycol 400 is a liquid, with a wide range of compatibility with various solvents, it is a good solvent and solubilizer, widely used in liquid preparations such as oral liquid, eye drops and so on. Polyethylene glycol is the preferred alternative when vegetable oils are not suitable for co-active ingredient carrier materials because polyethylene glycol is stable and non-perishable. In addition, injections containing polyethylene glycol are very safe and stable as long as it is heated to 150 degrees Celsius. In addition, it can be blended with high molecular weight PEG, the mixture has good solubility and drug compatibility.
Polyethylene glycol can be used as raw material ester surfactant.
PEG-200 can be used as organic synthesis medium, with high requirements of the heat carrier, used in the chemical industry in the humectant, inorganic salt solubilizer, viscosity regulator; for the textile industry in the softener, antistatic agent; Wetting agents for paper and pesticide industries.
Product usage
About 2,000 monomers of poly (ethylene glycol) molecules. Poly (ethylene glycol) is used in a variety of applications from industrial chemistry to biochemistry. Recent studies have shown that PEG has the ability to help restore the process of spinal cord injury, contribute to the animal's nerve impulse conduction process. In rats, it has been shown to help repair the chopped sciatic nerve shaft, helping to recover nerve damage. It is industrially produced for various surface lubricating substances to reduce friction. PEG is used to prepare vesicle transport systems and is used in diagnostic procedures or drug delivery methods.
