Polyethylene Glycol – PEG 400

Polyethylene Glycol – PEG 400

PEG 400 (Polyethylene Glycol 400) is a low molecular-weight grade of polyethyleneglycol. It is a clear, colorless, viscous liquid. Due in part to its low toxicity, PEG 400 is widely used in a variety of pharmaceutical formulations.

It is an effective ingredient, which finds application in variety of industries like food, pharmaceuticals, textile, chemical, biological and even the manufacturing process of polymers. Well, PEG or Polyethylene Glycol tends to be solvent in water, ethanol, methanol, acetonitrile, dichloromethane and benzene On the other hand, it is considered insoluble in diethyl ether as well as hexane. On getting joined with hydrophobic molecules on usage, PEG is intended to manufacture non-ionic surfactants. Apart from this, PEG happens to contain potential toxic impurities like dioxane and ethylene oxide.

Industries Where Polyethylene Glycol is mainly required :

  • Medical:
    It is considered as the base of laxatives and has been considered as important in manufacturing numerous medicines. On coupled with varied protein medications, PEGhappens to allow easy clearing of excessive protein in the blood.
  • Chemical:
    As a water soluble polymer, PEG is considered highly essential in creating osmotic pressures. Moreover, this exclusive ingredient is also helpful in conducting bio-membrane experiments. And also, it tends to prove fruitful in being used as preservatives.
  • Biological:
    Considering its effective use in biological turn, PEG is utilized for DNA isolation, fusion of B-cells with myeloma and making foam cushions Along with this, other side of biological use calls for concentrating viruses and creating ‘Gene therapy’ vectors. Not just limited to this, it is also used as a potentiator for boosting the detection process of antibodies and antigens.
  • Commercial:
    On getting combined with glycerine, it is exceptional for usage as skin creams and toothpaste. Apart from this, its low molecular formulations actors ink solvents and lubricants for print head.
  • Textile:
    PEG and its derivatives are extensively used as lubricants, softeners, conditioning agents and antistatic agents for processing as well as finishing aids for textiles. Apart from this, the usage also considered optimum for carding, spinning, knitting and weaving the fibres .
