Polyethylene glycol price
Polyethylene glycol (PEG) is a polyether consist of repeating units of ethylene oxide. .It has a molecular weight million, if you compare that to water that has a molecular weight of about 18. The polymer is known as A Liquid That Pours Itself because when you start pouring it, it will just keep pouring even after you tilt the container back.
This may be because of the fact that polyethylene glycol has high molecular weight due to long chains of molecules.
Properties of PEG:
- Isn’t displaceable due to high binding affinity of the thiol group to the particle surface
- Has A neutral charge
- Its Isoelectric Point: ~2.5
- Highly stable in a high concentration of salt
- Nontoxic and high biocompatible
- Compatible in solvents such as water, ethanol, chloroform, many other polar solve
- Its consistency is like a mucus
The uses of PEG:
- It has wide uses in a variety of applications including food additives as it is a non-toxic polymer. The polymer also works as a stealth coating to reduce non-specific binding as well as evade the body’s immune system.
- In the pharmaceutical industry: Polyethylene glycol 3350 works as a laxative to treat occasional constipation or irregular bowel movements since PEG increases the amount of water in the intestinal tract to stimulate bowel movements.
PEG3350can cause side effects such as severe or bloody diarrhea, rectal bleeding, blood in your stools, severe stomach pain, bloating, gas, dizziness and over sweating, in addition, it should contraindicate in pregnancy
- Polyethylene glycol 400 has common use in a range of applications, including the manufacture of cosmetics and personal care products, it works as a solvent, humectant, lubricant, and solubilizer.
The derivatives of PEG:
PEG Carboxyl Acid has a major uses in Lateral Flow and bioconjugation
Polyethylene glycol price
polyethylene glycol 3350 price is $12 for reconstitution of 119 grams, while the price of PEG 300 is$2 for kilogram.price vary according to the type and supplier of PEG.
