Plasticizing Agent Polyethylene Glycol 400 Peg 400 Industrial Grade

Properties

polyethylene oxide and water addition polymer.Molecular weight under 700,when 20ºC is colorless,odorless non-volatile viscous liquid,a little water.The molecular weight between 700~900 for semisolid.Molecular weight of more than 1000 and flocculant for shallow waxy white solid or flake or liquid paraffin wax powder.Mixing soluble in water,soluble in many organic solvents, such as alcohol, acetone, chloroform, and aromatic hydrocarbon;Insoluble in most of the fatty hydrocarbon and ether.With the increase of molecular weight and its water solubility,vapor pressure,the solubility of water and organic solvents,such as reduced, while freezing point, relative density, flash point and viscosity increase.On the thermal stability, and many chemicals do not work, not hydrolysis.
 
Basic info

English name: Poly real (ethylene glycol)
Chinese alias: ethylene glycol polyoxyethylene ether
CAS no. : 25322-68-3
Login EINECS no. : 203-473-3
Molecular formula: HO (CH2CH2O) nH
Melting point: 64-66 ° C
Boiling point: > 250 ° C
Density: 1.27 g/mL at 25 ° C
Vapor pressure: < 0.01 mm Hg (20 ° C)
Flash: 270 ° C
Solubility: soluble in water, ethanol, and many other organic solvents
 
Application 

1). Chemical uses
PEG is the basis of a number of laxatives. Whole bowel irrigation with polyethylene glycol and added electrolytes is used for bowel preparation before surgery or colonoscopy.PEG is also used as an excipient in many pharmaceutical products.When attached to various protein medications, polyethylene glycol allows a slowed clearance of the carried protein from  blood.
2). Medical uses
PEG is often used (as an internal calibration compound) in mass spectrometry experiments, with its characteristic fragmentation pattern allowing accurate and reproducible tuning.PEG derivatives, such as narrow range ethoxylates, are used as surfactants.PEG has been used as the hydrophilic block of amphiphilic block copolymers used to create some polymersomes.
3). Biological uses
PEG is commonly used as a precipitant for plasmid DNA isolation and protein crystallization. X-ray diffraction of protein crystals can reveal the atomic structure of the proteins.PEG is used to fuse two different types of cells, most often B-cells and myelomas in order to create hybridomas.
4). Commercial uses
PEG is the basis of many skin creams (as cetomacrogol) and personal lubricants (frequently combined with glycerin).PEG is used in a number of toothpastes as a dispersant. In this application, it binds water and helps keep xanthan gum uniformly distributed throughout the toothpaste.
