What is polyethylene glycol used in?

Polyethylene glycol, referred to as PEG, is used as an inactive ingredient in the pharmaceutical industry as a solvent, plasticizer, surfactant, ointments, and suppository base, and tablet and capsule lubricant.

What is the difference between propylene glycol and polyethylene glycol?

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. Historically the types of reactions these agents cause are dissimilar as noted above.

What common products contain polyethylene glycol?

Polyethylene glycol (PEG) is found in many skin creams, lotions, soaps, hair products and shower gels. PEGs are petroleum-based compound that are often used as thickeners, solvents, softeners, and moisture-carriers.

What is the use of PEG 400?

Generic Name: peg 400-propylene glycol 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.

What is PEG hydrogel?

Polyethylene glycol (PEG) hydrogels are widely used in a variety of biomedical applications, including matrices for controlled release of biomolecules and scaffolds for regenerative medicine.

What is propylene glycol used for?

It is used to absorb extra water and maintain moisture in certain medicines, cosmetics, or food products. It is a solvent for food colors and flavors, and in the paint and plastics industries. Propylene glycol is also used to create artificial smoke or fog used in fire-fighting training and in theatrical productions.

What is the difference between PEG 6000 and PEG 8000?

the number associated with the various pegs indicate the average molecular weight of the polymer. peg6000 and 8000 are the same, peg6000 was found to have an average fw of 8000 and was renamed. The clue is in the name – POLYethylene glycol!

What is the viscosity of PEG?

PEG 400 (polyethylene glycol 400) is a low-molecular-weight grade of polyethylene glycol. It is a clear, colorless, viscous liquid….PEG 400.
