Is polyethylene oxide the same as polyethylene glycol?
Polyethylene Oxide is a different material than Polyethylene Glycol even though the two materials have the same CAS number. The differences are molecular weight and the manufacturing process. Polyethylene Oxide should not be called Polyethylene Glycol.
Is PEO toxic?
Polyethylene glycol has a low toxicity and is used in a variety of products.
How is polyethylene oxide made?
PEOs are synthesized by polymerization of ethylene oxide using a metallic catalyst. They are available in a very wide molecular weight range, from 200 to 7.0 × 106 g/mol, and the low-molecular-weight PEOs are called PEGs. They are completely soluble in cold and warm water.
How long does injected polyethylene glycol stay in your system?
Among hydrophilic polymers, PEG has the advantage to be considered non-toxic and was approved by the Food and Drug Administration (FDA) for internal use in humans [61]. The blood half-life of PEG extended from 18 min to 1 day as the PEG molecular weight increased from 6 K to 190 K [62].
Is polyethylene glycol safe to ingest?
Polyethylene glycol electrolyte solution can cause dangerous or life-threatening side effects in people with these conditions. People with eating disorders (such as anorexia or bulimia) should not use this medicine without the advice of a doctor.
What are the dangers of polyethylene glycol?
COMMON side effects
- irritation of the rectum.
- a sleep disorder.
- excessive thirst.
- nausea.
- vomiting.
- stomach cramps.
- abdominal bloating.
- a feeling of general discomfort called malaise.
Why is PEO hydrophilic?
When dissolved in water, PEO is characterized by hydrophilic interactions (hydrogen bonding of water molecules to the oxygen atoms on the polymer) and hydrophobic interactions (the CH2CH2 groups repel water). PEO can dissolve in water only because water molecules form a sheath around the PEO macromolecule.
What is poly oxide?
noun. An oxide containing more than one oxygen atom in the molecule.
Is polyethylene an oxide a plastic?
Polyethylene is a kind of plastic. Polyethylene is a polymer of ethylene. The repeating units are H — (C2H4)n — H. Polyethylene glycols are polymers of ethylene oxide.
