What is polyethylene glycol 400 used for?
This medication is used to relieve dry, irritated eyes. Common causes for dry eyes include wind, sun, heating/air conditioning, computer use/reading, and certain medications.
Is Polyoxyethylene the same as polyethylene glycol?
Polyethylene glycol (PEG; ) is a polyether compound derived from petroleum with many applications, from industrial manufacturing to medicine. PEG is also known as polyethylene oxide (PEO) or polyoxyethylene (POE), depending on its molecular weight.
What is the meaning of polyethylene glycol 400?
PEG 400 (polyethylene glycol 400) is a low-molecular-weight grade of polyethylene glycol. 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. Polyethylene glycol. Names.
Is PEG 400 a solvent?
Abstract. Polyethylene glycol 400 (PEG400) is a commonly used co-solvent. Recent studies suggested that it might affect the systemic exposure of oral drugs based on mechanisms besides increasing their solubility.
Is polyethylene glycol 400 Safe?
Purpose: : Polyethylene glycol (PEG)-400 is a clear, colorless, viscous liquid that readily dissolves many hydrophobic drugs. It is a widely used commercial solvent and vehicle for many pharmaceutical and cosmetic products and safe for human oral consumption and topical application.
What is the difference between PEG 200 and PEG 400?
PEG 200 and PEG 400 are both mixtures of molecules of different sizes that differ in the number of oxyethylene units, with an average molecular weight of 200 and 400, respectively.
What is difference between PG and PEG 400?
PG and PEG have dissimilar chemical structures. PG is a small, single molecule with 3 carbons and 2 OH groups ( ie a double alcohol). PEG is a multi-unit polymer with a differing molecular weight and backbone.
What is polyethylene glycol 400 made from?
Polyethylene glycol 400 (PEG400) is a clear, colorless liquid used in many industries and applications. Typically derived from petroleum, Acme-Hardesty offers a sustainable alternative manufactured from the byproducts of sugar cane processing.
Is PEG 400 safe for eyes?
Conclusions: : Our findings indicate that the intravitreal injection of polyethylene glycol-400 is toxic to retina and it should not be used as a vehicle in the eye.
Is PEG 400 safe to consume?
It is toxic in very high doses, but the amounts used in the food industry are minimal and safe for human consumption. PEG 400 can be used as a sweetener, and as a carrier for flavor, including in vaping products as a carrier for flavor, with or without tobacco.
Is polyethylene glycol 400 toxic?
Can you buy polyethylene glycol over-the-counter?
Conclusions: Polyethylene glycol 3350, an osmotic laxative available over the counter, has been shown to be safe and effective in treating chronic constipation in children and adults, including the elderly, across multiple clinical trials, with a safety profile comparable to that of placebo.
Is propylene glycol the same as polyethylene glycol?
The key difference between polyethylene glycol and propylene glycol is that polyethylene glycol is a polymer, whereas propylene glycol is a single molecular compound that can be named a diol. Polyethylene glycol and propylene glycol are important organic compounds.

What does the number in PEG 400 or PEG 4000 indicate?
The numbers that are often included in the names of PEGs indicate their average molecular weights (e.g. a PEG with n = 9 would have an average molecular weight of approximately 400 daltons, and would be labeled PEG 400). Most PEGs include molecules with a distribution of molecular weights (i.e. they are polydisperse).
